Abstract:
A drive assembly includes a drive housing, a bearing-mounted wheel mount configured to rotate about a rotation axis with respect to the drive housing, and a shift assembly coupled between an input shaft and the wheel mount to selectably cause rotation of the wheel mount various rotational speeds. The shift assembly includes a gear set and a brake arrangement. The gear set has a first gear and a second gear, each being rotatable by the input shaft independent of the other. The brake arrangement has a first brake component and a second brake component. During rotation of the wheel mount at a first rotational speed, the first brake component brakes the first gear with respect to the drive housing. During rotation of the wheel mount at a second rotational speed, the second brake component brakes the second gear with respect to the drive housing.
