    Transmission assembly; method for assembling a transmission assembly
    The invention relates to a transmission assembly for a motor vehicle for transmitting power from a driving source to wheels of the vehicle.
    Transmission assemblies are known as part of a vehicle drive. Transmission assemblies typically include a transmission and a start-up device, as well as a stator plate for providing the hydraulic connection between the transmission and the start-up device.
    The transmission typically comprises a transmission housing and power transmission elements are provided within the transmission housing. The force transmitting elements, such as friction elements or transmissions or couplings, are usually hydraulically actuated by a hydraulic control unit. The hydraulic control unit comprises valves and control elements such as solenoids and is provided inside the transmission housing. The hydraulic control unit is often referred to as HCU or hydraulic circuit.
    The boot device is usually provided between the drive source and the transmission and is adapted for connection and / or separation of the transmission from the drive source. For example, during starting of the drive source, only the transmission is connected to the drive source if a certain rpm has been reached. For example, at a standstill, e.g. at a traffic light, the drive source is rotating, but the vehicle is not, so the transmission is separate from the drive source. The boot device then connects or separates the drive source with or from the transmission. The start-up device can be in the form of a coupling device or as a torque converter or as a gearbox module or as any other known start-up device.
    BE2017 / 5493
    The start-up device is hydraulically actuated and is hydraulically connected to the hydraulic circuit of the transmission. A stator plate is provided to provide this hydraulic connection between the start-up device on one side and the transmission on the other side. The stator plate includes channels for the hydraulic fluid and is coupled to the start-up device on one side and to the transmission on the other side. The hydraulic fluid for controlling the start-up device is controlled by the hydraulic control unit. The main hydraulic control unit controls all hydraulic actuation in the transmission assembly.
    For some drives it is advantageous to use a different start-up device than for other drives, depending on the available space in the vehicle, on the desired driver start-up experience, on costs etc. This requires a redrawing of the transmission, in particular of the hydraulic control unit of the transmission since a different type of start-up device requires a different hydraulic control. Such a redraw is often difficult since it takes time, can be difficult and can also influence development, installation, assembly and / or maintenance.
    There is a need to provide a transmission assembly that overcomes at least one of the aforementioned disadvantages.
    To this end, the invention provides a motor vehicle transmission assembly for transmitting power from a drive source to vehicle wheels, the transmission assembly comprising a transmission with a transmission housing and within the transmission housing power transferring elements actuated by a hydraulic control unit; a boot module arranged on an input side of the transmission, the boot module being configured to connect and / or separate the transmission with and / or from the drive source; wherein the start-up module is hydraulically actuated in fluid communication with the
    BE2017 / 5493 hydraulic control unit of the transmission; wherein the start-up module comprises a start-up device for providing the connection and / or separation between the transmission and the drive source, and a stator plate for providing the fluid connection between the start-up device and the hydraulic transmission control unit; wherein the stator plate comprises a hydraulic manifold with at least one valve for operating the hydraulic actuation of the start-up device.
    By providing the stator plate with a hydraulic manifold with at least one valve to hydraulically actuate the start-up device, the transmission, in particular the hydraulic control unit of the transmission, can remain unchanged when a different start-up device is coupled to the transmission assembly. A transmission assembly with a relatively large flexibility can thus be obtained at a relatively low cost. When a different type of startup device is selected, the transmission, typically within a transmission housing, can remain the same, and only the corresponding stator plate, with startup device-specific manifold, must be selected to obtain a modified transmission assembly. As such, a modular transmission assembly can be obtained that is versatile, relatively cost-effective, and relatively easy to adapt to different types of starting devices.
    Advantageously, the hydraulic manifold of the stator plate further comprises a valve control element for controlling the at least one valve of the manifold. By providing the hydraulic manifold of the stator plate with a valve control element, the modularity of the transmission assembly can be further increased, because the hydraulic manifold of the stator plate can be more easily adapted to different types of start-up devices. The transmission can also be further simplified and the cost of the transmission can be reduced. As such, the actuation and / or control of the
    BE2017 / 5493 at least one valve of the hydraulic manifold are more independent of the hydraulic control unit.
    The fluid connection between the manifold and the hydraulic control unit is preferably a direct fluid connection, i.e. without control of the hydraulic control unit. By providing a direct fluid connection, the control of the at least one valve of the hydraulic manifold can become independent of the hydraulic control unit. More preferably, a direct fluid communication is provided while there is a valve control element in the hydraulic manifold of the stator plate. This configuration can further increase the modularity of the transmission assembly, and the complexity and costs of the transmission can be further reduced.
    Advantageously, the stator plate is arranged for mechanical connection to the transmission housing, such that the fluid connection between the hydraulic control unit and the stator plate can be established manifold. By providing such mechanical connections, assembly of the stator plate with the transmission housing can be simpler and / or more reliable, which reduces the risk of errors, reduces assembly time, etc. Also, the fluid communication between the stator plate and the hydraulic control unit of the transmission housing can be be established in a more reliable and / or simpler manner. Advantageously, the stator plate is provided with matching elements arranged for cooperation with corresponding matching elements on the transmission housing. By providing the stator plate with matching elements arranged for cooperation with corresponding matching elements on the transmission housing, increased reliable assembly of the stator plate with the transmission housing can be obtained.
    The start-up module preferably comprises a start-up module housing in which the start-up device and the stator plate are accommodated. The
    BE2017 / 5493 boot module housing is placed over the boot device and the stator plate to connect to the transmission housing, preferably via connecting elements. The boot module housing thus serves as a cover for the boot device and the stator plate and, together with the transmission housing, can form a closed housing for the transmission assembly. Advantageously, the stator plate is connected to the transmission housing, then the start-up device can be coupled to the stator plate. The boot module housing can then be placed over the boot device and stator plate to be connected to the transmission housing via the connecting elements.
    Preferably, the stator plate manifold is in fluid communication with the start-up device via hydraulic channels. By providing this fluid connection through hydraulic channels, use can be made of the hydraulic channels available in the stator plate, as well as the fluid connection between the stator plate and the transmission. As such, an integrated hydraulic system can be obtained that can extend through hydraulic channels to the start-up device, while hydraulic manifold of the stator plate can hydraulically control the start-up device.
    By configuring the startup module for a specific type of startup device such that, upon selection of a type of startup device, the corresponding startup module is provided, the modularity of the transmission assembly is further improved. The interchangeability of a start-up device with respect to a transmission housing is also increased.
    Advantageously, the transmission housing is the same for different types of start-up devices, to provide for further reduction of the complexity and / or costs of the transmission assembly.
    In a preferred embodiment of the transmission assembly, an output axis of the drive source engages the startup module that is
    BE2017 / 5493 configured to engage an input axis of the transmission. As such, the transmission assembly can be connected to the drive source in a compact and / or simple manner to receive torque from the drive source.
    In another aspect of the invention, a stator plate is provided which comprises at least one hydraulic channel and at least one manifold which is adapted for connection to a hydraulic control unit of a transmission on one side and for connection to a start-up device on another side. By providing a stator plate with at least one hydraulic channel and at least one manifold, the stator plate can be adjusted according to the requirements of the start-up device while, in particular, the transmission inside the transmission housing can remain unchanged. Thus, the stator plate can be relatively easily adapted to different start-up devices without the need to change the transmission when a different start-up device is used, which is cost-effective.
    Advantageously, the stator plate is provided for use in the transmission assembly. By providing a stator plate in or use in a transmission assembly, the transmission, and in particular the hydraulic control unit of the transmission, can remain unchanged when a different start-up device is coupled to the transmission. Thus, a transmission assembly with a relatively large flexibility can be obtained at a relatively low cost. When a different type of start-up device is selected, the transmission can remain the same, and only the corresponding stator plate, with a start-up device-specific manifold, must be selected to obtain a modified transmission assembly. As such, a modular transmission assembly can be obtained that is versatile, relatively cost-effective, and relatively easy to adapt to different types of starting devices.
    BE2017 / 5493
    In yet another aspect of the invention, there is provided a method for assembling a transmission assembly, comprising: providing a transmission with a transmission housing and within the transmission housing power-transmitting elements actuated by a hydraulic control unit; providing a first type of start-up module configured to connect and / or separate the transmission to and or from the drive source; wherein the first type of start-up module is configured for hydraulic operation in fluid communication with the hydraulic control unit of the transmission; comprising a first type of start-up device and a corresponding first type of stator plate; providing at least a second type of start-up module configured to connect and / or separate the transmission with and or from the drive source; wherein the second type of start-up module is configured for hydraulic operation in fluid communication with the hydraulic control unit of the transmission; comprising a second type of start-up device and a corresponding second type of stator plate; selecting one of the multiple types of boot modules; assembly the selected type of start-up device with the transmission provided. Preferably, by providing a single type of transmission, and multiple types of start-up devices together with corresponding start-up device-specific stator plates, an easy-to-assemble and cost-effective transmission assembly can be achieved. Depending on a selected type of start-up device, the corresponding stator plate is selected and assembled to the single available transmission. Thus, the transmission assembly can be easily adjusted with another start-up device and corresponding stator plate while the transmission can remain unchanged.
    Further advantageous elaborations are proposed in the subclaims.
    BE2017 / 5493
    The invention will be further explained with reference to a drawing. The figures in the drawing are given by way of exemplary elaboration forms. In the drawing:
    Figure 1: a schematic representation of an embodiment of a transmission assembly according to the invention;
    Figure 2: a schematic hydraulic diagram of a transmission assembly according to the invention.
    In the drawing, the figures are only given as a schematic representation of the invention. Corresponding elements are indicated with corresponding reference characters.
    Figure 1 shows a motor vehicle transmission assembly 1 for transmitting power from a drive source 2 to the wheels of the vehicle. The drive source 2 can be a combustion engine, or can be an electric machine. This transmission assembly 1 comprises a transmission 3 with a transmission housing 4. Within the transmission housing 4, power transmission elements 5 are provided which are actuated by a hydraulic control unit 6. The power transmission elements 5 can be designed as a known type of power transmission elements, such as transmissions, friction elements, etc. for providing a manual or automatic transmission of the power from the drive source to the wheels. Such force-transmitting elements are known from the prior art and are not further explained here. Figure 1 shows a schematic representation of a transmission 3 of the continuously variable transmission CVT type 7 with pulleys 7a, 7b and a flexible member 7c between them to transfer torque from a primary pulley 7a to a secondary pulley 7b. As stated, this transmission can also be designed as a different type of transmission. A transmission is typically provided to provide an appropriate speed ratio and torque to the wheels in different driving conditions.
    BE2017 / 5493
    Between the drive source 2 and the transmission 3, a start-up module 8 is usually provided which is adapted for connection and / or separation of the transmission from the drive source, for example during starting of the drive source, or while the vehicle is stationary. The start-up module 8 is arranged on an input side 9 of the transmission 3, this start-up module 8 being configured to connect and / or separate the transmission 3 with the drive source 2 and / or the drive source 2. This connection and / or separation can often be done by a hydraulic actuation of the start-up module 8, which is in fluid communication with the hydraulic control unit 6 of the transmission 3. The start-up module 8 preferably comprises a start-up module housing 10 for enclosing a start-up device 11 and a stator plate 12. The start-up module housing 10 is adapted for mechanical connection to the transmission housing 4 by means of connecting elements 13, for example designed as a bolt-nut or pin-hole or a flange connection. For example, the start-up module housing 10 and transmission housing 4 can both be provided with a flange on the outer circumference that allows the connection of the start-up module housing 10 and transmission housing 4 to the connecting elements 13. The boot module housing 10 and transmission housing 4 can then, when connected together, form a transmission assembly housing 14. Thus, the startup module housing 10 is open to be placed over the startup device 11 and the stator plate 12 to provide coverage of the startup module 8. As such, a direct mechanical and / or hydraulic connection between the transmission housing 4 and stator plate 12 is possible.
    The start-up module 8 comprises the start-up device 11 for providing the connection and / or separation between the transmission 3 and the drive source 2. Such a start-up device 8 is known from the prior art, and may, for example, but not limited to, torque converters,
    BE2017 / 5493 are wet couplings or dry couplings. These types of start-up devices are not further explained as such.
    The start-up module 8 is provided with the stator plate 12 for providing the fluid connection between the start-up device 11 and the hydraulic transmission control unit 6. As such, the hydraulic fluid can be supplied from the hydraulic transmission control unit 6 to the start-up device 11 for actuating the start-up device 11, via the stator plate 12. The stator plate 12 comprises a hydraulic manifold 15 with at least one valve 16 for operating the hydraulic actuation of the start-up device 11. Thus, the actuation of the start-up device 11 can be operated by the hydraulic manifold 15 of the stator plate 12, and not, as in prior art systems, by the hydraulic transmission control unit. Other valves 17 and / or channels (not shown) may be provided in the hydraulic manifold 15 to actuate other hydraulic components of the transmission assembly, such as actuation of a DNR (Drive-Neutral-Reverse) coupling (not shown) around the transmission 3 provide a forward, neutral and reverse mode. Another valve 17 can be provided for, for example, the actuation, lubrication and / or cooling of other couplings or any other component in the assembly 1, as shown in Figure 2.
    The hydraulic manifold 15 of the stator plate 12 in the transmission assembly 1 can further comprise a valve control element 18, such as a solenoid, for controlling the at least one valve 16 of the hydraulic manifold 15. Thus, the actuation of the start-up device 11 can also be controlled by the hydraulic manifold 15 of the stator plate 12, and not, as in prior art systems, by the hydraulic transmission control unit. It may also be possible that the hydraulic manifold 15 comprises a plurality of valve control elements 15 for controlling the plurality of valves 16, 17 in the hydraulic manifold 15.
    BE2017 / 5493
    A pump system (not shown) supplies hydraulic fluid to the hydraulic control unit 6 and via the hydraulic control unit 6 the hydraulic fluid is distributed to the hydraulic manifold 15 in the stator plate 12, as well as to hydraulic components in the transmission 3. The hydraulic manifold 15 is in direct fluid communication with the hydraulic control unit 6, ie without control of the hydraulic control unit 6. Without control of the hydraulic control unit 6, the pressure and / or flow of the hydraulic fluid is controlled by a valve 16, 17 and / or valve control element 18 of the stator plate manifold 15.
    In Figure 1, the pump system (not shown) supplies hydraulic fluid via a hydraulic line 19a to the hydraulic control unit 6. From the hydraulic control unit 6, hydraulic fluid is distributed, preferably without any control, to the hydraulic manifold 15 via a direct fluid connection through hydraulic line 19b. However, it may also be a possibility that the hydraulic control unit 6 partially controls the hydraulic fluid to the stator plate manifold 15. In the case of partial control by the hydraulic control unit, one or more valve control elements 18 are provided in the hydraulic control unit 6 which controls the valve 17 in the hydraulic manifold 15. Figure 1 shows an embodiment in which the hydraulic fluid for actuating the start-up device 11 is at least partially controlled by the hydraulic manifold 15. Hydraulic fluid is supplied from the hydraulic manifold 15 to the start-up device 11 via a hydraulic line 19c. The supply of the hydraulic fluid through the fluid connection via the hydraulic line 19c is controlled by the hydraulic manifold 15 and more specifically by at least one valve 16 and preferably also by a control valve element 18.
    In the transmission assembly 1, the stator plate 12 is adapted to be mechanically connected to the transmission housing 4, such that the fluid communication between the hydraulic control unit 6 in the
    BE2017 / 5493 transmission casing 4 and the stator plate manifold 15 in the stator plate 12 can be located quite easily.
    The mechanical connection of the stator plate 12 with the transmission housing 4 can comprise matching elements 20 which are provided on the stator plate 12 which are adapted to cooperate with corresponding matching elements 21 which are provided on the transmission housing 4. These corresponding matching elements 21 on the transmission housing 4 are arranged in such a way that matching elements 20 of several types of stator plates 11 can cooperate with the corresponding matching elements 21. The mechanical connection of the matching elements 21 of the stator plate 12 with the transmission housing 4 can be made possible in at least two different configurations . In a first configuration, the matching elements 20 provided on a plurality of stator plates 12 may be substantially the same for the plurality of types of stator plates and are adapted to interact with the corresponding matching elements 21 of the transmission housing 14. As a result, the corresponding matching elements may 21 on the transmission housing 4 are limited to a minimum number of corresponding matching elements 21, because the multiple types of stator plates 12 are all provided with substantially the same interface of matching elements 20.
    In a second type of mechanical connection, each type of stator plate 12 can comprise different matching elements 20 and / or a different device matching elements 20 relative to the matching elements 20 or the device matching elements 20 of another type of stator plate 12. Thus, at least two different types of stator plates comprise different matching elements 20 and / or different devices of matching elements 20. The transmission housing 4 can then be provided with
    BE2017 / 5493 a plurality of sets of matching elements 21, each set of matching elements 21 cooperating with a set of matching elements 20 of a specific type of stator plate 12. The matching elements 20 of the multiple types of stator plates 12 can thus cooperate with a corresponding set of matching elements 21 of the single type of transmission housing 4. Thus, the transmission housing 4 comprises at least the corresponding matching elements 21 that are required to cooperate with the matching elements 20 of a plurality of types of stator plates 12. In this way, the modularity of the stator plate 12, and hence of the startup module 8, retained in providing stator plates 12 that include different mating elements 20 and / or different arrangement of mating elements 20. For example, a modular start-up device 8 can be provided that can interact with a single type of transmission housing 4.
    Thus, the matching elements 20, 21 are provided for establishing a mechanical connection between the stator plate 12 and the transmission housing 4. The fluid connection can be established via fluid connection points, in combination with the matching elements or elsewhere. By providing the mating elements 20, 21, the mechanical connection and alignment of the stator plate 12 with respect to the transmission housing 4 can be achieved. In particular, when the alignment of the stator plate 12 with respect to the transmission housing 4 is obtained, it can also provide the alignment of the fluid connection points such that the fluid connection can be established more easily. In this way the connection increases the modularity of the transmission assembly 1.
    The stator plate manifold 15 is in fluid communication with the start-up device 11 via hydraulic channels in the stator plate 12 which are in fluid communication with hydraulic channels or hydraulic paths in
    BE2017 / 5493 the start-up device 11. The fluid connection between the hydraulic channels in the stator plate 12 and the start-up device 11 can be established via well-known hydraulic connection points. Furthermore, the stator plate 12 can be provided with more hydraulic channels to guide hydraulic fluid to other components in the transmission assembly 1, such as couplings. In some embodiments of the stator plate, hydraulic fluid can be added to hydraulic components in the transmission housing, e.g., a coupling, or the force-transmitting elements 5, via the stator plate 12. Then, the stator plate 12 is used only for guiding the hydraulic fluid to the designated part, while the hydraulic control of the designated part was done by the hydraulic control unit 6.
    The startup module 8 of the transmission assembly 1 can be configured for a specific type of startup device 11, such that, upon selection of a specific type of startup device 11, the corresponding startup module 8 is provided. For a specific type of start-up device 11, a specific type of stator plate 12 is required. For example, if the start-up device 11 is a torque converter, the stator plate 12 is designed to couple with the torque converter. Alternatively, if the start-up device 11 is a coupling device, the stator plate 12 is designed to couple with the coupling device. As such, a startup module 8 can be obtained that is specific to a specific type of startup device 11, thereby obtaining a modular transmission assembly 1, while the transmission 3, with the transmission housing 4, can remain the same regardless of the selected type of startup module 8.
    The drive source 2 supplies torque and rotational speed via a drive source output shaft 23 to a transmission module input shaft 24. The transmission module 1 then transmits the force and torque torque of the drive source to an output shaft 22 of the transmission module 1
    BE2017 / 5493 for driving a load, such as wheels of a vehicle. The output shaft 23 of the drive source 2 engages the start-up module 8, the start-up device 11 being configured to engage an input shaft 24 of the transmission module 1. The start-up device 11 can separate or connect the torque coupling path from the output shaft 23 of the drive source 2 to the input shaft 24 of the transmission module 1. This connection and / or separation can be achieved hydraulically or mechanically. A mechanical connection can be achieved by a start-up device which is designed as, for example, a wet coupling, which is known from the prior art. A hydraulic connection or separation can be achieved by a hydraulic start-up device 8 such as a torque converter, which is also known from the prior art. Both the wet clutch and the torque converter are hydraulically actuated. However, other types of start-up devices can also be used.
    The stator plate 12 comprises at least one hydraulic channel and at least one hydraulic manifold 15 adapted for connection to the hydraulic control unit 6 of the transmission 3 on one side and for connection to the start-up device 8 on another side, e.g. via hydraulic connection points. However, the stator plate 12 can also comprise more hydraulic channels for the distribution of hydraulic fluid to other components.
    The stator plate 12 can also comprise more than one hydraulic manifold 15. Providing more than one manifold 15 in the stator plate can be advantageous for controlling the hydraulic actuation, hydraulic lubrication or hydraulic cooling of a plurality of devices, for example for controlling hydraulic fluid to the start-up device 11 and / or the power transferring elements 5, wherein each manifold 15 can at least partially control a hydraulic function of a device. Thus, by providing multiple manifolds 15 in the stator plate 12, the functionality of the stator plate 12 can be achieved
    BE2017 / 5493. Moreover, by providing more than one manifold 15 in the stator plate 12, the ease of replacement or maintenance of the valves 16, 17, 18 in the stator plate 12 can also be increased. Thus, the maintenance or replacement of valves, 16, 17, 18 of the stator plate manifold 15 may be less complex than the maintenance or replacement of valves 16, 17, 18 in the hydraulic control unit. Thus, by providing the stator plate 12 with more than one manifold 15, the hydraulic control unit 6 can become more robust, while maintenance or replacement of the error-prone valves 16, 17, 18 can be made less labor-intensive.
    One or more stator plate manifolds 15 can be integrated as an integral part of the stator plate 12, but these manifolds 15 can also be provided as interchangeable modules. By providing the manifold as an exchangeable module, the assembly and / or maintenance and / or repair of the manifold can become simpler. These manifold modules can then preferably be interchangeable with the stator plate 12, which increases the modularity and flexibility in use of the stator plate 12. The modular manifold modules can increase the ease of replacement or maintenance of valves 16, 17, 18 in the manifolds 12 and / or increase the ease of adjusting the stator plate 12 when, for example, another start-up device 11 is provided in the transmission assembly 1 For example, the manifold module can be replaced with a different manifold module if a different type of start-up device is to be connected to the stator plate. Alternatively, if a manifold has failed or otherwise requires maintenance, it can be removed and replaced with another manifold module.
    A method is also provided for assembling a transmission assembly 1 as shown in Figure 1. The method comprises the following steps.
    BE2017 / 5493
    The first step is to provide a transmission 1 with a transmission housing 4 and within the transmission housing 4, the power transmitting elements 5 are provided that are actuated by the hydraulic control unit 6 of the transmission 3. The second step is to provide multiple types of start-up modules 8 , preferably at least a first type of startup module 8 and at least a second type of startup module 8. The first type of startup module 8 is configured for connection and / or separation of the transmission 3 with and / or from the drive source 2. The first type of startup module 8 is here configured for hydraulic operation in fluid communication with the hydraulic control unit 6 of the transmission 3, comprising a first type of start-up device 11 and a corresponding first type of stator plate 12. The at least second type of start-up module 8 is configured for connection and / or separation of the transmission 3 with and / or from the drive source 2. The second type of stand up rt module 8 is configured for hydraulic operation in fluid communication with the hydraulic control unit 6 of the transmission 3 and comprises a second type of start-up device 11 and a corresponding second type of stator plate 12. In a further step, a single of the multiple types of start-up modules 8 is selected. In a final step, the selected type of start-up module 8 is assembled with the transmission 3 provided to provide a transmission module 1. The transmission 3 provided may preferably be a single type of transmission 3 independent of the plurality of startup modules 8.
    Figure 2 shows a schematic hydraulic diagram of the hydraulic circuit comprising the control unit 6 and the stator plate manifold 15. The hydraulic manifold 15 may be in direct fluid communication with the hydraulic control unit 6. In this configuration, the hydraulic fluid supplied by hydraulic line 19a is from a pump system (not shown) then directly supplied to the stator plate manifold 15 via the hydraulic control unit 6 and hydraulic line 19b. In
    In this configuration, the hydraulic manifold 15 drives the start-up device 11 through the valve control 18 and the valve 17. The valve control 18 is preferably a solenoid that electrically controls the valve 17 with electrical pulses 25, the valve 17 controlling the pressure and / or determines flow from the hydraulic line 19c. The hydraulic manifold 15 can also include other valves 17 and other valve control elements 18 that can also be used for actuation, cooling and / or lubrication of other components in the transmission assembly 1. Also, channels (not shown) can be provided in the hydraulic manifold 15 which be able to function purely as a distribution of hydraulic fluid, such as hydraulic line 19d. In this latter example, the hydraulic fluid is controlled by control valve elements 18b and valves 17a of the hydraulic control unit 6.
    In an alternative embodiment, the start-up device 11 may be partially controlled by the hydraulic manifold 15, because a valve control element 18a is formed in the hydraulic control unit 6 which controls the valve 16 of the hydraulic manifold 15. Thus actuation of the start-up device 11 is done from the manifold 15 with the valve 16, since this start-up device is specific, while the control of the valve 16 is done by the hydraulic control unit 6, in particular by a valve control element such as a solenoid, which is more independent may be of a specific type of start-up device 11. As such, a relatively simple and robust yet start-up device-specific manifold and stator plate can be obtained, while the relatively expensive part of the solenoid can remain in the hydraulic control unit.
    Advantageously, the manifold of the stator plate, which may be designed as an interchangeable manifold module, includes all manifold parts that are adjusted when peripheral parts of the transmission assembly are adjusted. The transmission assembly includes a transmission with a transmission housing and peripheral parts that
    BE2017 / 5493 can be connected for this purpose. Such a peripheral component is the boot device, other peripheral components can be a coupling, or a DNR module, etc. When such a peripheral component is adjusted, the manifold in the stator plate is advantageously adapted to the selected peripheral component. As such, an optimum modular transmission assembly is obtained. The transmission itself can be the same for all types of peripheral parts, while, by providing the stator plate with a manifold and then adjusting the manifold of the stator plate, a modified modular transmission assembly can be obtained with limited effort and with limited cost. By providing the stator plate with a manifold through which peripheral parts, such as a start-up device, can be provided with hydraulic fluid, preferably also can be actuated via a valve in the manifold, more preferably also can be controlled via a control element, e.g. a solenoid, in the manifold, a modular system can be obtained in which the relatively expensive and complex transmission can remain unchanged when different types of peripheral components are connected to the transmission.
