A drive train for a steerable drive wheel of a vehicle includes a spur gear stage and a bevel gear stage in a drive train housing which is supported for pivotal movement about a vertical axis. The drive wheel is driven through a horizontal axis from a vertically arranged motor. The housing is divided so that the axle-base change of the spur gear stage which is necessary when changing the drive wheel width requires different parts only for the part of the drive train housing which surrounds the spur gears. The remaining part of the drive train housing, which contains the bevel gear stage, is always the same. A slewing ring can be integral with the housing part which surrounds the spur gears. Furthermore, an opening for supplying or discharging air to or from the motor chamber can be provided.
A drive train for a steerable drive wheel of a vehicle, comprising a drive train housing which can be supported on the vehicle frame for pivotal movement about a vertical axis by a slewing arrangement, which drive train housing is divided into an upper housing which houses a spur gear stage and a lower housing which houses a bevel gear stage, the upper and lower housings being connected at a junction, a pinion of the spur gear stage being mounted on the drive shaft of a motor mounted on the upper housing coaxial with the drive train housing pivot axis and engaging a further gear mounted on a vertical bevel-pinion shaft of the bevel gear stage, which shaft extends across the junction, a bevel gear being mounted on a horizontal driven shaft, one end of which driven shaft projects from the drive train housing and supports a drive wheel, the bevel-pinion shaft and the driven shaft being rotatably supported in the lower housing and the slewing arrangement being mounted on the upper housing.
