An axle assembly including a housing in which is mounted a transmission, axle shafts and a differential assembly including drive gears engaged to the axle shaft and at least one planet gear mounted on a shaft and engaged to the drive gears. The differential assembly includes a friction member on the shaft for engaging the planet gear.

Transaxle with controlled traction differential

An integrated hydrostatic transaxle including a housing in which is mounted a hydrostatic transmission having a hydraulic pump unit and a hydraulic motor unit with a motor shaft drivingly connected thereto. A differential assembly is drivingly linked to the motor shaft and is used to drive output axle shafts of the transaxle. The differential assembly includes a rotatable gear which is maintained in frictional engagement with at least one bearing surface for frictionally inhibiting the rotational movement thereof.

Controlled traction cartridge and differential for a hydrostatic transmission

An integrated hydrostatic transaxle including a housing in which a center section is supported. The center section supports a hydraulic pump unit and a hydraulic motor unit having a motor shaft drivingly connected thereto. A differential assembly is drivingly linked to the motor shaft and is used to drive a pair of axle shafts which are supported by the housing. The differential assembly includes a rotatable gear which is maintained in frictional engagement with at least one bearing surface for frictionally inhibiting the rotational movement thereof.
