    A transmission provided with a hydraulically controlled variableV-belt drive (2) in combination with a fluidcoupling or torque convertor (1) (hydrodynamic unit) can be provided with a lock-up (15,16,17) to close (lock) the hydrodynamic unit i.e. to have a direct mechanical connection between the input shaft (4) and the output shaft (10) of said unit. Said lock-up is operable depending on the fluid pressure in the hydraulical operating cilinder (8) of the primary pulley of the V-belt drive.

    01 The invention relates to transmissions for vehicles equipped with an infinitely variable belt drive with a V-belt. A known transmission for an automobile contains a hydrodynamic transmission unit installed in the housing, one of the elements of which is connected to the drive engine, and a V-belt variator, including the driving and driven pulleys, mounted respectively on the driving shaft connected to the other component of the hydrodynamic assembly, and the driven shaft each of which is made of a first conic C (th disk, rigidly connected with the corresponding shaft, and a second conical disk mounted on the corresponding shaft with the possibility of an axis, This movement with respect to the first disk by means of a hydraulic working cylinder, as well as a device for locking the hydrodynamic transmission unit, implemented as a C 1 3 disk clutch. The disadvantage of the transmission is that there is a constant speed difference between the primary and secondary hydrodynamic transmission units. shafts, i.e., slip, which is loss of power. In order to eliminate this disadvantage, there is a known method of imparting to a hydrodynamic transmission node Fittings for locking the said transmission assembly. Such a locking clutch, or stopper, provides a direct mechanical connection between the primary and secondary shafts of the hydrodynamic transmission unit, for example, by means of a disk clutch. The disadvantage of using a stopper is the difficulty of controlling it, for example, adjusting the clutch lockout during periods when the hydrodynamic transfer unit is not used for tripping or for increasing torque, since this adjustment requires less special operating valve. The aim of the invention is to simplify management. This goal is achieved by the fact that the transmission for the car, which contains a hydrodynamic transmission unit installed in the housing, one of the elements of which is connected to the drive engine, and a wedge-variable gearbox, including the common drive and driven shafts, mounted respectively on the drive shaft. associated with other ephemeig. a hydrodynamic unit, and a driven shaft, each of which contains a first conical disk rigidly connected with a corresponding shaft, and a second conical disk mounted on the corresponding shaft with the possibility of axial movement relative to the first disk by means of a hydraulic working cylinder, and a blocking device hydrodynamic transfer unit, in the form of a shche clutch, the latter is placed in an oil bath, while the control cavity of the clutch engagement is connected by hydraulic rolling to the cavity; Started second, denote shshindrom. The drawing shows a variant of transmission (constructive execution). Hydraulic clutch 1, associated with the primary pulley 2 of the V-belt: the variator, contains the impeller 3 of the turbine 5, directly connected to the primary pin 2 of the variable transmission. Primary pin 2 contains a conical disk 6 rigidly connected to the primary shaft 7, and a conical disk 8 axially movable on the primary shaft 7. The working diameter of the V-belt 9 in the primary pulley 2 is determined by the gap between the disks 6 and 8. With the maximum The V-belt 9 lies at the minimum working diameter in the pulley 2. By tensioning the V-belt 9 with the side side, the disk 8 is pressed against the stopper 10 connected to the shaft 7. The disk 8 functions as a piston in the working cylinder 11 rigidly connected to the a partial shaft 7 and closing the cavity 12 of the cylinder. By supplying the working fluid or discharging it from the cavity 12 of the cylinder through the coaxial channel 13 for the working fluid, made inside the input shaft 7, the gap can be changed and changed, thereby changing the working diameter of the V-belt 9 on the primary pulley 2. Thereby It is possible to adjust the equilibrium position between the pressure of the working fluid in the cavity 12 of the cylinder and the tension force in the V-belt 9. The transmission ratio of the variable V-belt transmission is thus adjusted by supplying or releasing the working fluid from the cylinder chamber 12, the fluid pressure should always be sufficiently high to ensure equilibrium with the force of tension in the V-belt.
    The transmission is also equipped with a disk clutch with discs 14 rigidly connected to the input shaft 4, and squeaks 15 mounted on the primary shaft 7. Depending on the pressure of the working fluid in the channel 13, the piston 16 pushes the discs 14 and 15 to each other, and a direct mechanical connection is established between shafts 4 and 7. Thus, o6paaoMt hydrodynamic transmission wyeel can be blocked, for example, depending on the pressure of the working fluid that prevails in cavity 12 ai and vdr.
    Due to the construction shown in the drawing, depending on the pressure of the working fluid in the channel 13 (and in the cylinder 12 cavity), a locking device with discs can be put into action
    14 and 15 and match 16 and adjust the gear ratio of the V-belt tie of the villa. Thus, the blocking of the blocking of its device occurs at a pressure of the working fluid that is not enough; Along the displacement of the cisca 8 with preoolation, the tension exerted by the V-belt 9 in the shaft from the stopper 10, whereas during the displacement of the disc 8 there is always 1 high pressure of the working fluid
    and the locking device remains locked.
    In addition, the drawing shows a portion of the wall of the crankcase 17 separating the transmission clutch assembly from the V-belt transmission. A channel 18 is made in the wall to supply the working fluid to the clutch 1. There is also an opening 19 for the release of fluid flowing through the bearing 20. The pressure of the working fluid prevailing in the hydraulic clutch 1 ensures the release of the disks 14 and
    15 clutches.
    As shown in the drawing, the transmission is equipped with seals 21-23 to prevent fluid from leaking at these locations.
    The invention provides the ability to control, by using the same valve for working fluid, both the transmission ratio of the variable wedge belt transmission and the blocking and unlocking of the stopper. As long as the transmission ratio of the V-belt variable remains maximum, i.e. in low gear conditions, the drive belt runs along the primary pulley of maximum working diameter, due to which the gap between the conical disks is maximum and they are pushed to the stoppers by means of tension of the wedge belt. Due to this, before the valve on which the V-belt transmission begins to shift, the pressure of the working fluid in the primary cylinder can change without causing consequences, and this pressure of the working fluid MOSH1O can be used to actuate the locking device. While the V-belt transmission is variable under high gear conditions, there is always pressure of the working fluid in the primary cylinder to maintain the locking device in the locked position.
    Due to this use of the fluid pressure in the primary cylinder to actuate the blocking of the hydrodynamic transmission unit, simplicity of construction is achieved, and therefore either the torque converter, or the hydraulic clutch, functions as such, and the pregnant transmission is in lower gear, or the torque converter, respectively, the hydraulic differential, not function | 1shoniruet (blocked), and variable, the transmission affects the transmission of the transmission. The same sources of operating fluid and the unloading valve can, therefore, adjust the gear ratio of the simultaneous transmission, as well as activate the locking device.
