A wheel head transmission (1) comprising a first and second shafts (W1, W2) which are connected to one another via a planetary transmission (PG). The wheel head transmission (1) comprises first and second planetary stages (P1, P2), which include a first element (E11, E12), a second element (E21, E22) and a third element (E31, E32). The first element (E11) of the first planetary stage (P1) is connected to the first shaft (W1) for conjoint rotation, the second element (E21) of the first planetary stage (P1) and the third element (E32) of the second planetary stage (P2) are connected to one another and the second shaft (W2) for conjoint rotation. The third element (E31) of the first planetary stage (P1) and the first element (E12) of the second planetary stage (P2) are connected together for conjoint rotation, and the second element (E22) of the second planet stage (P2) is immobilized.

A transmission (G) for a motor vehicle includes a housing (GG), a shaft (W, GW2, DS1, DS2) 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, GW2, DS1, DS2) and the housing (GG), and a sleeve-shaped covering element (C) fixedly connected to the shaft (W, GW2, DS1, DS2) 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).

A torque converter disposed between a prime mover and an output shaft is disclosed. The torque converter includes a cover, an impeller, a turbine, and a first clutch. The impeller is unitarily rotated with the cover. The turbine is disposed opposite to the impeller. The first clutch is configured to allow and block transmitting power outputted from the prime mover to the cover.

A drive apparatus includes a motor having a rotor with a hollow motor shaft and a stator, a gear connected to the rotor, a housing including a motor housing accommodating the motor, and a gear housing at one side in an axial direction of the motor housing and accommodating the gear, and a passage. The gear includes a hollow gear shaft connected to one side in the axial direction of the motor shaft. The passage includes a first portion connecting the inside of the gear housing and the inside of the gear shaft, a second portion at least partially configured by the inside of the gear shaft and the inside of the motor shaft and connected to the first portion, a third portion connected to the second portion on the other side in the axial direction, and a first supply portion connected to the third portion and above the stator.

Methods and systems for an electric drive assembly are provided herein. In one example, a method for operation of an electric drive system is provided that includes coordinating operation of a first electric drive unit and a second electric drive unit based on a first power request. In the system, each of the first and second electric drive units include a planetary gear reduction that delivers power from a pair of motors to a set of axle shafts, and the planetary gear reductions have asymmetric gear ratios.

A multipurpose vehicle includes a stepless speed changer which is provided at one of lateral sides of a vehicle body with respect to an engine and a traveling transmission, an engine output shaft projected from the engine toward the stepless speed changer along a lateral direction of the vehicle body, a speed changer input shaft projected from the stepless speed changer toward the engine along the lateral direction of the vehicle body, and a first gear transmission mechanism provided between and across the engine output shaft and the speed changer input shaft and transmitting power of the engine output shaft to the speed changer input shaft. The multipurpose vehicle further has a PTO section provided at the side of the stepless speed changer with respect to the engine and forwardly of the stepless speed changer, the PTO section being operably connected to the engine output shaft via a second gear transmission mechanism.

A controller drives a shifting actuator to move a first engagement member from an original position of a first engagement portion in one direction along a relative motion path and acquires first position information representing a first position, the first position being a position where the first engagement portion moved in the one direction contacts a second engagement portion. The controller drives the shifting actuator to move the first engagement member from the original position in the other direction along the relative motion path and acquires second position information representing a second position where the first engagement portion moved in the other direction contacts the second engagement portion. The controller calculates a center position of the first engagement portion on the relative motion path from the acquired first position information and the acquired second position information, compares the calculated center position to the original position.
