A drive assembly for a work vehicle includes a drive housing, a drive shaft rotatable about a drive axis, an inner hub rotationally fixed to the drive shaft, and a planetary gear set coupled to the drive shaft and configured to selectively rotate an output element. The drive assembly also includes a clutch arrangement having a clutch ring configured to selectively engage the planetary gear set. The clutch arrangement further includes a guide assembly mounted on the clutch ring and configured to selectively interact with the planetary gear set to effect disengagement of the clutch ring from the planetary gear set. A clutch actuation assembly is configured to effect movement of the clutch arrangement along the drive axis to engage the planetary gear set, and a guide actuation assembly is configured to operate the guide assembly to interact with the planetary gear set.

A first driving device includes a motor including a rotating shaft, a speed reducer, and a supporting member. The speed reducer includes a rigid gear, a flexible gear configured to partially mesh with the rigid gear, and a wave motion generator coupled to the rotating shaft and configured to come into contact with the inner circumferential surface of the flexible gear, bend the flexible gear, and move a meshing position of the rigid gear and the flexible gear in the circumferential direction. The wave motion generator includes a projecting section projecting along the rotating shaft. The rotating shaft is supported by the supporting member via a bearing including an inner ring and an outer ring. The outer ring of the bearing is supported by the supporting member. The rotating shaft and the projecting section are coupled to the inner ring of the bearing by tight fitting.

An actuation system includes a power drive unit that drives a plurality of drive shafts that each has a first end individually connected to the power drive unit. The power drive unit includes a geartrain including a plurality of individual gears that are offset relative to each other along the gearbox, and a motor-driven rotation of one of the plurality of individual gears drives rotation of the other individual gears, and each of the plurality of individual gears rotates to drive rotation of a respective one of the plurality of drive shafts. A plurality of torque brakes is mounted to the gearbox, the torque brakes being mechanically coupled to respective individual gears and drive shafts. When the torque being passed through is above a predetermined threshold value, a locking of one of the torque brakes stops rotation of all gears simultaneously to maintain positional symmetry in the actuation system.

A power steering assembly includes an electric motor having an output shaft extending therefrom. The assembly also includes a housing containing a worm gear operatively coupled to a steering shaft, the worm gear rotatable about a worm gear axis. The assembly further includes an electric motor and a worm arranged to engage the worm gear, the worm extending from the output shaft of the electric motor as a single, integrally formed shaft, the single, integrally formed shaft extending axially from a first end to a second end and being cantilevered to allow the second end to deflect. The assembly yet further includes a bushing surrounding a portion of the shaft proximate the second end of the shaft, the bushing and the portion of the shaft defining a clearance therebetween.

The invention relates to drive apparatus for adjustment devices of motor vehicles comprising an at least two-part housing (1), in which an electric drive unit (2) and a gear unit (3) which is operatively connected to said electric drive unit are arranged, characterized in that the housing (1) is designed as part of the gear unit (3).

A hybrid-electric powertrain includes an internal combustion engine, a transmission, and an electric machine, where the electric machine is connected to the transmission for transmitting torque. The transmission has a transmission housing, within which there is disposed an output-side gear set assembly, and also a transmission housing cover disposed on an output side of the transmission as seen in an axial direction. The electric machine has a stator, a rotor, a rotor shaft connected to the rotor for conjoint rotation, and an electric machine housing. In addition, the electric machine has a connection housing for connecting the electric machine to the transmission housing. The rotor shaft of the electric machine is disposed parallel to a transmission input shaft of the transmission.

A servo and a robot with the same are provided. The servo comprises a servo body, an upper cover, a lower cover, and a gear set having a plurality of gears meshing with each other. The gear set is located in the servo body, and comprises an output gear located in the center of the servo body as seen from the cross section of the servo body.

A geared motor includes a gear unit, a first, a second, or a third electric motor, and an adapter part situated between the gear unit and the electric motor. On its side facing the electric motor, the adapter part has a first, a second, and a third centering device, and on the side facing away from the electric motor, it is connected to the gear unit. The centering devices are radially set apart from one another, and the second centering device is situated radially between the first and third centering devices. The electric motor has an axially protruding centering ring, which is centered by only a single one of the centering devices of the adapter part, and the other centering devices are radially set apart from the centering ring and/or have no centering function, e.g., for the centering ring.

A servo and a robot are provided. The servo includes: a servo body, an upper cover fixedly connected to the top of the servo body, a lower cover fixedly connected to the bottom of the servo body, and a direct-current motor, a motor gear and a gear set which are arranged between the servo body and the upper cover and in driving connection with one another in sequence, wherein the servo comprises a first part and a second part protruding from the first part, and the gear set comprises an output gear located at the second part.

A driving force transmitting device includes an axle housing and a transaxle main body. The axle housing includes a supporting body and two shafts extending in opposite directions from the supporting body. The supporting body has an internal space. The transaxle main body is supported by the supporting body. The axle housing further includes a first breather plug. The first breather plug is fixed to the supporting body and is configured to discharge a gas in the internal space to an outside. The transaxle main body includes a gear mechanism, a case that accommodates the gear mechanism, and a second breather plug. The gear mechanism is configured to transmit a driving force.
