    Preferred embodiments of the present invention are described in this document, as required; it should be understood, however, that the preferred embodiments described herein are intended merely to serve as examples for the present invention that can be carried out in several and different alternative ways. Figures are not necessarily to scale; some features can be exacerbated or minimized to reveal the details of certain components. In this way, the specific details of the structural and functional part described in this document should not be interpreted in the sense of limiting it, serving merely as a representative basis for teaching the specialist in the technique for use in different forms of the present invention.
    Referring to Figures 1-3, an example of a driving axle assembly 10 is shown. The driving axle assembly 10 can be arranged with a motorized vehicle, such as a truck, bus, agricultural equipment, military transport or armed vehicle, or with equipment for transporting cargo by land, air or sea.
    The drive axle assembly 10 may be part of a vehicle drive assembly that can transmit torque to one or more sets of drive wheels, which may include a wheel-mounted tire. One or more driving axle assemblies 10 can be arranged with the vehicle. For example, the driving axle assembly 10 shown in Figure 1 can be part of a tandem driving axle configuration or a multiple tandem driving axle configuration that includes several sets of drive axles that can be connected in series.
    In at least one preferred embodiment, the driving shaft assembly 10 can include a housing 20, a differential 22, at least one driving shaft 24, at least one hose of lubricant 26, in addition to at least one reservoir module 28.
    The housing 20 can receive several components of the driving axle assembly 10. Furthermore, the housing 20 can promote the assembly of the driving shaft assembly 10 in the vehicle. The housing 20 may include several components that can be assembled together in a suitable manner, such as by means of welding and / or with one or more fasteners. In at least one preferred embodiment, the housing 20 may include a central portion 30, a differential carrier portion 32, in addition to at least one arm portion 34.
    The central portion 30 can be arranged close to the center of the housing 20. The central portion 30 can define a cavity 40 which can receive at least a portion of the differential 22. The region of the cavity 40 located below the differential 22 can define at least in part of a crankcase portion 42 which may contain a lubricant 44.
    Lubricant 44 can slide down the sides of the central portion 30 and accumulate in the crankcase portion 42. Lubricant 44, which may be oil, can lubricate the components of the driving axle assembly 10, as is the case with differential 22.
    The differential holder portion 32 may be arranged close to the central portion 30. The differential holder portion 32 may support the components of the differential 22 and may further define a cavity that receives at least a portion of the differential 22. At least In a preferred embodiment, the differential holder portion 32 can be coupled to the central portion 30 in a suitable manner, for example with one or more fasteners such as a pin.
    One or more arm portions 34 can extend from the central portion 30. In the preferred embodiment illustrated in Figure 1, two arm portions 34 are arranged that extend in opposite directions from the central portion 30 and the differential 22. One arm portion 34 or a portion thereof may be integrally formed with the central portion 30 in one or more preferred embodiments. Each arm portion 34 can define an arm cavity 46 which can receive a driving shaft 24 and a reservoir module 28, as will be discussed in more detail below. The arm portion 34 and the arm cavity 46 may be arranged above the crankcase portion 42 in one or more preferred embodiments. In this way, the lubricant 44 that is released from a reservoir module 28 can slide down to the crankcase portion 42. Each arm portion 34 may also have a terminal flange 48 that is disposed near one end of the arm portion 34 .
    Differential 22 can be arranged in housing 20. Differential 22 can be configured to transmit torque to the drive wheel assemblies for the vehicle and allow the drive wheel assemblies to rotate at different speeds. In Figures 1 and 2, the input fork 50, the annular gear 52 are highlighted, in addition to an optional output fork 54, to facilitate a summary analysis of the operation of the differential 22.
    Inlet fork 50 can provide coupling of driving shaft assembly 10 to a source of torque. For example, the input yoke 50 can be coupled to a drive shaft that can be coupled to the outside of a vehicle's transmission. Alternatively, the input fork 50 can be coupled to a connecting shaft or drive shaft which can be coupled to an output fork 54 of another driving shaft assembly 10. The input fork 50 can be arranged on an input shaft which can be rotatably supported by one or more bearings which can be arranged in turn in the differential carrier portion 32 of the housing 20. The torque that is transmitted to the input yoke and input shaft can be transmitted to the ring gear 52 through the various intermediate gears and the output fork 54, if present. The torque can be transmitted from the ring gear 52 to each driving axle 24 and from each driving axle 24 to at least one set of driving wheels corresponding to it.
    The ring gear 52 can rotate about an axis and can splash the lubricant 44 that accumulates in the crankcase portion 42 as it rotates. As will be discussed later in greater detail, this lubricant 44 can be retained and stored in the reservoir module 28 to reduce the volume of lubricant 44 in the crankcase portion 42 under various conditions. Reducing the volume of lubricant 44 in the crankcase portion 42 can reduce the frictional drag that can be exerted on the annular gear 52 by the lubricant 44, which can improve the fuel economy of the vehicle.
    One or more driving axles 24 can transmit torque from differential 22 to a set of drive wheels. In Figures 1 and 2, two driving axes 24 are shown so that each driving axis 24 extends through a different cavity of the arm 46. The driving axes 24 can extend along and can rotate around an axis 60 through differential 22. Each driving axle 24 may have a first end and a second end. The first end can be coupled to the differential 22. The second end can be arranged opposite the first end and can be located outside the housing 20. A drive shaft flange 62 can be arranged on the second end which can promote the hub assembly wheel and drive wheel assembly. A shaft bearing can be arranged between the first and second ends of the driving shaft 24 to rotatively support the driving shaft 24. The shaft bearing can be located between the reservoir module 28 and the driving shaft flange 62 in one or more preferred achievements.
    At least one lubricant hose 26 can be arranged to route lubricant 44 to a reservoir module 28. Lubricant hose 26 can be configured to receive or retain lubricant 44 which is splashed or sprayed into housing 20 by differential 22. In at least one preferred embodiment, the lubricant hose 26 or a portion thereof may be configured in the form of an open groove or groove that can receive lubricant 44 which is sprayed or splashed by ring gear 52 or drips into a inner surface below in the central portion 30. Said groove or flute can face upwards or be generally removed from the crankcase portion 42 but can also include an opening through which lubricant 44 can be received. The lubricant hose 26 can also be configured to direct the lubricant to the differential 22, although it may be spaced away from the ring gear 52 so as not to interfere with the rotation of the ring gear 52 or to remove the lubricant 44 from the surfaces of the ring gear .
    The lubricant hose 26 can extend along an internal surface of the central portion 30 and the arm portion 34 of the housing 20 in one or more preferred embodiments. For example, the lubricant hose 26 can be integrally formed with the housing 20. Alternatively, the lubricant hose 26 can be arranged as a separate component that can be coupled to the housing 20 in a suitable way, such as by means of welding or with a fastener. In addition, the lubricant hose 26 or a portion thereof can also tilt downwardly from the central portion 30 of the housing 20 to a reservoir module 28 to promote the flow of lubricant 44 to a reservoir module 28.
    Lubricant hose 26 can route lubricant 44 to one or more reservoir modules 28. For example, a single lubricant hose 26 may be provided which has opposite ends that end in different reservoir modules 28. Alternatively, the lubricant hose lubricant 26 can supply lubricant 44 to a single reservoir module 28, as described in the preferred embodiment illustrated in Figure 2. More specifically, two lubricant hoses 26 are illustrated in Figure 2 which supply lubricant 44 to different reservoir modules 28. In said preferred embodiment, the lubricant hose 26 may include a first end 70 and a second end 72.
    The first end 70 can be arranged in the cavity 40 of the central portion 30 to assist in retaining the lubricant 44, as previously described. At least a portion of the lubricant hose 26 in the central portion 30 or adjacent to the first end 70 may include an upward opening 74. In Figure 2, opening 74 extends from the first end 70 to the second end 72. A said opening 74 can be arranged by removing the upper section of a pipe or tube in one or more preferred embodiments or by integrally forming a groove or groove with the housing 20, as previously analyzed. Alternatively, the first end 70 or other portion of the lubricant hose 26 may be fluidly connected with a pump or else receive lubricant 44 which is supplied by a pump. In this way, the pump can be used to pump lubricant 44 out of the crankcase portion 42 and to the reservoir module 28 through one or more lubricant hoses 26.
    The second end 72 can be arranged opposite to the first end 70. The second end 72 can be located in the arm portion 34 of the housing 20 and can end at the entrance or adjacent to an entrance of the reservoir module 28. The region adjacent to the second end 72 may be closed or include a closed portion 76 to assist in retaining lubricant 44 within lubricant hose 26 as it is routed to reservoir module 28. For example, closed portion 76 of lubricant hose 26 it can define a through hole through which lubricant 44 can flow. In at least one preferred embodiment, the closed portion 76 may start at the central portion 30 and may end at the reservoir module 28. Alternatively, the closed portion 76 may be omitted in one or more preferred embodiments.
    At least one reservoir module 28 can be arranged to receive lubricant 44 and / or store a volume of lubricant 44 that could somehow accumulate in the crankcase portion 42. The reservoir module 28 can be arranged in at least a portion arm 34 of housing 20.
    Referring to Figures 2 and 3, a first preferred embodiment of a reservoir module 28 is shown. In this preferred embodiment, the reservoir module 28 can include a first end plate 80, a second end plate 82, a portion of tube 84 , in addition to a set of side plates 86 that can collaborate to define at least in part a reservoir cavity 88 that is configured to store a volume of lubricant 44. In Figure 3, reservoir cavity 88 is partially filled, although may contain a greater or lesser volume of lubricant 44.
    The first end plate 80 can face differential 22 and can engage one or more surfaces of the arm portion 34 to help position the reservoir module 28. The first end plate 80 can include a tube opening 90, a first outlet 92 and, as an option, a first outlet valve 94.
    The first outlet 92 can be configured as a through hole that can extend through the first end plate 80 into the reservoir cavity 88. The first outlet 92 can be arranged generally below the tube opening 90. At least In a preferred embodiment, the first outlet 92 can be sized to control the flow of lubricant 44 out of the reservoir cavity 88. For example, the first outlet 92 can be sized so that the volume of lubricant 44 flowing out of the reservoir module 28 exceeds the volume of lubricant 44 flowing into the reservoir module 28 at low vehicle speeds (i.e., low differential rotation speeds) although it is less than the volume of lubricant 44 flowing out of the module reservoir 28 at high vehicle speeds (ie at high differential speeds).
    The first outlet valve 94, if present, can control the flow of lubricant 44 out of the reservoir cavity 88 through the first outlet 92. The first outlet valve 94 can have any suitable configuration. For example, the first outlet valve 94 can be a passive valve, as is the case with a bimetallic valve that can include different metals or metal alloys that expand at different rates in response to temperature. As such, a bimetallic valve can be configured to open at higher service temperatures across the drive shaft assembly, to allow lubricant 44 to flow from reservoir module 28 to crankcase portion 42 and close at lower temperatures . The first outlet valve 94 can also be an active valve that can include an actuator. For example, an active valve may have a pneumatic, hydraulic, electric or electromechanical actuator, which can be controlled by means of a controller 98, as will be analyzed in more detail below.
    The second end plate 82 can be arranged at an opposite end of the reservoir module 28 with respect to the first end plate 80. Similar to the first end plate 80, the second end plate 82 can fit on one or more surfaces of the arm portion 34 to help position the reservoir module 28. The second end plate 82 may also include a tube opening 90, and optionally, a second outlet 100 and a second outlet valve 102.
    The second outlet 100, if present, can be configured as a through hole that can extend through the second end plate 82 to the reservoir cavity 88. The second outlet 100 can be generally arranged below the tube opening 90 and can be configured to supply lubricant 44 to an axle bearing. In at least one preferred embodiment, the second outlet 100 can be sized to control the flow of lubricant 44 out of the reservoir cavity 88. The flow of lubricant 44 may be due to the inlet pressure exerted by the lubricant 44 in the cavity reservoir 88. Alternatively, a second outlet valve 102 can be provided to control the flow of lubricant 44 out of reservoir cavity 88 through second outlet 100. The second outlet valve 102 can be a passive valve or an active valve , as previously analyzed, with reference to the first outlet valve 94.
    The tube portion 84 may extend from the first end plate 80 to the second end plate 82 and may be spaced from the driving axis 24. In at least one preferred embodiment, the tube portion 84 may extend in a manner along axis 60, with a generally cylindrical shape. In at least one preferred embodiment, the tube portion 84 can be configured to curve with respect to the driving axis 24 to promote the installation. For example, tube portion 84 may be made of a flexible material, such as a polymeric material such as plastic, rubber or synthetic rubber, such as neoprene. In addition, lubricant 44 can also pass through tube portion 84 to feed lubricant 44 to a shaft bearing. For example, lubricant 44 can splash and flow along tube portion 84 as it can also be carried along the driving shaft 24 through the tube portion 84 towards the second end plate 82 and can flow through the driving shaft 24 or the reservoir module 28 to lubricate an axle bearing or other components that may be located on the outside, in relation to the second end plate 82.
    The set of side plates 86 can include one or more elements that can define at least part of one side of the reservoir module 28. Each side plate 86 can extend from the first end plate 80 to the second end plate 82. At least At least one preferred embodiment, each side plate 86 can be arranged adjacent and can fit at least one other side plate 86. In the preferred embodiment illustrated, four side plates 86 are shown that fit at least two other side plates 86 to provide a box-like configuration in which opposite pairs of side plates 86 are arranged and which are substantially parallel to each other. In this way, the reservoir cavity 88 can be disposed between the side plates 86 and the tube portion 84, therefore presenting a closed cavity which allows the reservoir cavity 88 to extend around the driving axis 24 in a shape of the type ring. This configuration can promote the storage of lubricant without widening the housing 20 or the arm portions 34 to increase the volume or space available in the housing 20. In addition, the side plate 86 disposed near the bottom of the arm portion 34 may be arranged above the crankcase portion 42 in one or more preferred embodiments, so that the lubricant 44 released from the reservoir module 28 can flow downward or be subjected to the force of gravity for the crankcase portion 42.
    The reservoir module 28 can be manufactured in any suitable form. For example, the reservoir module 28 can be made of a polymeric material that can be blow molded or include various metallic components that can be welded or somehow joined together.
    Reservoir module 28 may also include an inlet 104 that receives lubricant 44 from lubricant hose 26. Lubricant hose 26 may be arranged adjacent to inlet 104 or extend through inlet 104 in one or more preferred embodiments. Inlet 104 can be configured as a through hole and can be provided on the first end plate 80 or on a side plate 86 in several preferred embodiments. In the preferred embodiment illustrated in Figure 2, the inlet 104 is arranged on the side plate 86 which is located at the top of the reservoir module 28 and adjacent to the first end plate 80.
    Referring to Figures 4 and 5, another preferred embodiment of a reservoir module 28 'is shown. In this preferred embodiment, side plates 86 are omitted, resulting in a reservoir module 28 'that can include a first end plate 80', a second end plate 82 ', in addition to a portion of tube 84' that can collaborate with the portion arm 34 of the housing 20 to define at least in part a reservoir cavity 88 'that is configured to store a volume of lubricant 44. As such, the arm portion 34 can define at least in part the reservoir cavity 88'. In said preferred embodiments, heat can be transferred from the lubricant 44 to the arm portion 34 to help reduce the temperature of the lubricant 44 in the reservoir cavity 88 '.
    The first end plate 80 'may face differential 22 and may be arranged in close proximity or may engage one or more surfaces of the arm portion 34 to help position the reservoir module 28'. The first end plate 80 'can include a tube opening 90, a first outlet 92 and, optionally, a first outlet valve 94 such as the first end plate 80 of the reservoir module 28. In addition, the first end plate 80 'can have an inlet 104' and a seal 106 '.
    Inlet 104 'can receive lubricant 44 from lubricant hose 26 and can be arranged above first outlet 92. In at least one preferred embodiment, inlet 104' can also be arranged above tube portion 84 '. The inlet 104 'can be a through hole or it can be arranged adjacent to an edge or an edge surface for the first end plate 80', such as an upper edge surface, in several preferred embodiments.
    Seal 106 'can be provided to assist in retaining lubricant 44 in reservoir cavity 88'. The seal 106 'can be arranged along the perimeter or along one or more edge surfaces 108' of the first end plate 80 '. As such, seal 106 'can be arranged between and can engage the first end plate 80' and arm portion 34 of housing 20 to prevent lubricant 44 in reservoir cavity 88 'from leaking or passing around the first 80 'end plate.
    The second end plate 82 'can be arranged at an opposite end of the reservoir module 28' with respect to the first end plate 80 '. Similar to the first end plate 80 ', the second end plate 82' can be arranged in close proximity or can fit on one or more surfaces of the arm portion 34 to help position the reservoir module 28 '. The second end plate 82 'can also include a tube opening 90, and optionally a second outlet 100 and a second outlet valve 102 similarly to the second end plate 82 of reservoir module 28. In addition, the second end plate 82 'may also include a seal 106' similar to that which could be provided with the first end plate 80 '.
    Referring again to Figure 2, controller 98 can be configured to activate the first outlet valve 94 and / or the second outlet valve 102 between an open position and a closed position. In the open position, lubricant 44 may be able to flow through the respective outlet, such as the first outlet 92 or the second outlet 100. In the closed position, lubricant 44 may be prevented from flowing through the respective outlet, as is the case. from the first output 92 or the second output 100. Controller 98 can also receive data or a signal from one or more sensors, such as a volume sensor 110 and / or a differential temperature sensor 112, which can be used to control the performance of the first and / or second outlet valves 94, 102.
    Volume sensor 110 can be arranged on reservoir module 28, 28 'and can be configured to detect or provide a signal indicating a volume of lubricant 44 in reservoir cavity 88, 88'. Controller 98 can open the first and / or second outlet valves 94, 102 whenever the volume of lubricant 44 exceeds the volume limit value and can close the first and / or second outlet valves 94, 102 whenever the lubricant volume 44 does not exceed the volume limit value. The volume limit value can be established, based on the vehicle's performance tests.
    The differential temperature sensor 112 can be arranged in housing 20 and can be configured to detect or provide a signal indicating a temperature close to differential 22. For example, the differential temperature sensor 112 can detect lubricant temperature 44 in the crankcase portion 42. Controller 98 can open the first and / or second outlet valves 94, 102 when the differential temperature exceeds the differential temperature limit value and can close the first and / or second outlet valves 94, 102 when the differential temperature does not exceed the differential temperature limit value. The temperature limit value can be established, based on the vehicle's performance tests.
    Although examples of preferred embodiments have been described above, said preferred embodiments are not to be understood as covering all possible forms for the present invention. The terms used in the specifications are more descriptive than restrictive terms, so it should be understood that several changes can be made without, however, deviating from the idea and scope of the present invention. In addition, the characteristics of the various ways of implementing the preferred embodiments can be combined to form other preferred embodiments of the present invention.
