A transmission (G) for a motor vehicle includes a housing (GG), a shaft (W, GW, DS, DS) mounted in the housing (GG) and protruding from the housing (GG), a radial shaft seal (DR) having a sealing lip for sealing an oil space (NR) within the housing (GG) with respect to an exterior, a shaft grounding device (E) arranged on an exterior side of the radial shaft seal (DR) for establishing an electrically conductive sliding contact (SK) between the shaft (W, GW, DS, DS) and the housing (GG), and a sleeve-shaped covering element (C) fixedly connected to the shaft (W, GW, DS, DS) for protecting the sliding contact (SK) against environmental influences. The shaft grounding device (E) is fixedly connected to the housing (GG). The covering element (C), together with the grounding device (E), forms a labyrinth sealing. An electric axle drive (EA) may include the transmission (G).

Transmission for a motor vehicle, and electric axle drive

A transmission for a motor vehicle includes a housing and a gear set. An oil drainage channel is formed by the housing and/or by an element connected to the housing and is arranged spatially underneath the gear set. The oil drainage channel includes at least one gear set-side inlet port, a closed underside, and an oil sump-side outlet port at one end of the oil drainage channel, which are designed and arranged in such that oil from the gear set enters the oil drainage channel through the at least one inlet port and is guided along the closed underside to the outlet port. A suction port of a hydraulic unit of the transmission is arranged in the oil sump spatially underneath the closed underside of the oil drainage channel and axially offset with respect to the outlet port.

A hybrid drive unit (HY, G) for a motor vehicle includes a housing (GG), in which a torque converter (TC) and an electric machine (EM) are accommodated. The electric machine (EM) and the torque converter (TC) are arranged directly next to each other such that the electric machine (EM) is arranged at a first face end (TC) of the torque converter housing (TCG). An oil guide shell (LS) at least partially encompasses a section of the torque converter (TC). The oil guide shell (LS) has an L-shaped cross-section including a first section (LS) and a second section (LS) and is arranged in such that the first section (LS) partially encompasses a second face end (TC) of the torque converter housing (TCG) and the second section (LS) partially encompasses a circumferential surface of the torque converter housing (TCG).

A planetary transmission includes a planetary gear set (), another planetary gear set (), a fluid line () through which fluid is flowable to the planetary gear set () and to the other planetary gear set (), and a fluid collecting device () which is in fluid communication with the fluid line (). The fluid collecting device () is connected in a rotationally fixed manner to the planetary gear set (). The fluid collecting device () is configured for dividing the fluid from the fluid line () which has flowed into the fluid collecting device () into a fluid part which is flowable to the planetary gear set () and another fluid part which is flowable to the other planetary gear set ().

A drivetrain is proposed for a hybrid motor vehicle, which comprises an electric machine arranged between the vehicle's transmission () and a differential () of a driven axle in order to drive the axle via a Cardan shaft () or another shaft capable of torque transfer in which a transmission () made as a reducing gear system is arranged in the force flow direction behind the electric machine in order to produce the necessary speeds and torques and transfer them to the Cardan shaft or to the other shaft.

Drivetrain of a hybrid motor vehicle

A clutch disk arrangement for a multi-disk clutch has a hub rotatable about an axis of rotation and a plurality of friction lining assemblies connected to the hub by a torsional vibration damper arrangement. The torsional vibration damper arrangement includes a central disk element on the hub and a cover disk element on each side of the central element, where the cover disk elements are permanently connected to each other and are connected by a damper element arrangement to the central disk element for transmitting torque. A driver formation is provided on at least one of the cover disk elements and an opposing driver formation is arranged on at least one of the friction lining assemblies. The driver formation engages the opposing driver formation so that the at least one of the friction lining assemblies is fixed with respect to rotation and is axially displaceable.

Clutch disk arrangement for a multi-disk clutch

A pressure plate arrangement for a friction clutch includes a housing rotatably fixed to an abutment arrangement for joint rotation about an axis of rotation and a plate arrangement with at least one intermediate plate and a pressure plate. At least one of the intermediate and pressure plates is mounted in the housing and axially movable relative thereto and rotateable about the axis of rotation. An energy storage device coupled to the housing generates an elastic restoring force on the plate arrangement. A releasing spring arrangement located between the housing and plate arrangement is tensioned to generate an elastic restoring force on the pressure plate in a second direction opposite to the first direction. A clutch disk arrangement is clamped between the abutment arrangement and the at least one intermediate plate, or between any two plates of the plate arrangement.
