A transaxle includes a planetary gear reducer (40) and a differential device (80). The planetary gear reducer (40) includes a stepped pinion, a first needle bearing, a second needle bearing, and a carrier. The stepped pinion includes a pinion shaft with which a large diameter pinion and a small diameter pinion are integrated. The first needle bearing is fitted to a part of the pinion shaft outside the large diameter pinion. The second needle bearing is fitted to a part of the pinion shaft outside the small diameter pinion. The carrier is configured to support the stepped pinion via the first needle bearing and the second needle bearing such that the stepped pinion is rotatable with respect to the carrier, and to couple the stepped pinion and the differential device (80).

Electric portal axle (1) for the electric drive of a motor vehicle, with two spur gear stages (13, 14) for driving two wheels of the axle, wherein the portal axle (1) has a single electric machine (2) to which a transmission (5) and a differential (7) are arranged, and wherein the portal axle (1) further comprises a housing (28), characterized by the fact that the transmission (5) is a switchable transmission (5) with freewheel (6), the switchable transmission (5) is designed as a planetary gear set, and for switching two gear stages of the portal axle (1) the latter has a switching means (23), wherein in a first gear stage a ring gear (9) of the transmission (5) and a housing-fixed clutch body (27) are connected and a clutch (29) which is arranged between the ring gear (9) and a planet carrier (11) of the transmission (5) is open, and wherein in a second gear stage the ring gear (9) and the housing-fixed clutch body (27) are separated and the clutch (29) is closed, the clutch (29) is designed as a friction-fit clutch, wherein the clutch (29) is arranged between the switching means (23) which is connected to the ring gear (9) in a torque-transmitting manner and the planet carrier (11).

A tandem wheel assembly for a work vehicle includes a tandem wheel housing having a central opening extending along a pivot axis and a wheel end opening extending along an associated wheel end axis. The tandem wheel housing is pivotally mounted to a chassis of the work vehicle about the pivot axis. A central sprocket is rotatably disposed within the tandem wheel housing. Wheel end assemblies are disposed at the wheel end openings and each include a wheel end sprocket, a wheel end gear train, and a wheel end hub. A pair of reaction rods are pivotally coupled at first ends to the chassis and at second ends to components of respective wheel end assemblies. A pivot damping system is positioned at least partially axially between the tandem wheel housing and the components of at least one of the chassis or the wheel end assemblies. The pivot damping system is configured to dampen pivoting of the tandem wheel housing relative to the chassis.
