Lubricating performance of a parking brake is ensured and fuel efficiency during traveling is improved. A parking brake for braking rotation of an output shaft is disposed around the output shaft rotated by driving force. The output shaft is provided with an axial oil passage, a first discharge hole, and a second discharge hole. The axial oil passage extends in an axial direction of the output shaft. The first discharge hole and the second discharge hole communicate with the axial oil passage and open in an outer circumferential surface of the output shaft at an installation position of the parking brake in the axial direction.

A compact transmission, in particular for use within a single-wheel drive unit, includes a gear carrier fixed to the frame, which has a continuous central recess, and a main transmission having an internally toothed ring gear rotatably mounted on the outside of the gear carrier, externally toothed gears arranged in front of the one of the end faces of the gear carrier and meshing with the ring gear, and an input sun shaft. The compact transmission further includes a transmission pre-stage arranged within the central recess, and a pre-stage input shaft having an externally toothed pre-stage sun wheel, a pre-stage ring gear, and at least one pre-stage intermediate gear meshing with both the pre-stage sun wheel and with the pre-stage ring gear. An additional carrier is fastened to the transmission carrier, via which the pre-stage intermediate gears are held captively in the central recess.

In some examples, a brake assembly includes an actuator assembly configured to cause the translation of a piston to compress a disc stack. The actuator assembly is configured to generate a first torque around a motor axis using a motor and generate a second torque from the first torque using a harmonic drive. The actuator assembly may include a gear set configured to cause a linear actuator to translate the piston using the second torque. In some examples, the actuator is configured to translate the piston along a compression axis different from the motor axis.

A multi-disc brake includes an annular brake coil holder with a wound brake coil, an armature plate with a disc support to which a multiplicity of armature plate discs is fastened. A compression spring brings about a linear spacing of the brake coil holder from the armature plate made of a ferromagnetic material in a braking position of the multi-disc brake and, when current is applied to the brake coil, a released position of the multi-disc brake can be created by attracting the armature plate in the direction of the brake coil holder. The braking effect results from the interaction of the armature plate discs with drive shaft discs on a drive shaft. The brake coil holder area of the brake coil holder and the cross-sectional area of the brake coil are substantially of rectangular single-legged design, and when installing the multi-disc brake, part of the wall of the drive support surrounds the brake coil on two sides and the brake coil holder on one side.
