A drive axle for a work machine for driving wheels that are coupled to the drive axle. The drive axle includes a spur gear stage with an input shaft. A differential gear unit couples to the spur gear stage and to the wheels via wheel drive shafts. The drive axle further includes a reduction gear unit with an output element couples to the input shaft of the spur gear stage—and an input element which couples to an output shaft of an electric drive machine.

Bearings (72, 74) are arranged for a drive unit (10) having an electric motor for providing drive to an electric axle and a wheel assembly of a vehicle. The drive unit includes a pair of bearings and a reduction gear assembly (12) with a first drive gear mounted to and coaxial with the main shaft of the motor, and a first driven gear rotatably coupled to the first drive gear and mounted to and coaxial with an intermediate shaft to form an intermediate shaft assembly. The reduction gear assembly includes a second drive gear mounted to and coaxial with the intermediate shaft, and a second driven gear rotatably coupled with the second drive gear. A first bearing of said pair of bearings is mounted to a bulkhead and to said intermediate shaft assembly between the first driven gear and second drive gear to reduce the distance between the first and second bearings.

A transmission lubrication system for a vehicle providing a continuous return flow of a lubricant. The transmission lubrication system includes a differential housing, a transmission housing, a lubricant tank, a suction line, a lubricant pump, and an air suction pump. The transmission housing is connected to the differential housing in an air-tight manner and a lubricant through-passage is provided between the transmission housing and the differential housing. The lubricant tank is provided in the differential housing and has a lubricant suction opening in a lower region. The lubricant pump conveys lubricant from the lubricant tank through the suction line and conducts the lubricant to the lubrication points in the differential housing and transmission housing. The air suction pump pumps air from the lubricant tank into the transmission housing so that an excess air pressure is maintained in the transmission housing.

A sensor assembly configured for use with a locking differential received in a differential case includes a sensor housing, a switch element and a sense element. The sensor assembly is configured to determine a position of an armature in relation to a stator. The armature moves relative to the stator between engaged and disengaged positions corresponding to the locking differential being in a locked and unlocked state. The sensor housing is coupled relative to the differential case of the locking differential. The switch element is disposed in the sensor housing. The sense element moves with the armature. The sensor assembly is configured to change state based on a position of the sense element.

A final drive differentially for distributing torque input into a shaft via a differential device to a pair of axles is provided with a ring gear coupled via gearing to the shaft to transmit the torque to the differential device. A housing unitarily includes a main portion supporting the shaft and enclosing the differential device, and a wall portion including a first opening through which one of the axles passes and supporting a first end of the differential device. A cover included a second opening through which the other of the axles passes, and is combined with the housing to support a second end of the differential device, wherein the wall portion, the ring gear, and the shaft are arranged, from the wall portion toward the cover, in an order of the wall portion, the ring gear, and the shaft.

A vehicular differential device includes a differential rotation mechanism, and a torque input member that receives drive torque, the drive torque is distributed and transmitted to a first drive shaft and a second drive shaft. The differential rotation mechanism includes an input gear that rotates as a unit with the torque input member, an output gear that rotates as a unit with the first drive shaft, a first gear and a second gear that rotate as a unit, and a carrier that supports the first gear and the second gear, the carrier being configured to rotate as a unit with the second drive shaft. The gear ratio between the input gear and the first gear is different from that between the output gear and the second gear. During differential rotation, the first drive shaft and the second drive shaft are rotated in opposite directions.
