A universal joint shaft with universal joint shaft protection comprises at least one shaft element for transmitting torque, at least one protective tube element arranged around the shaft element, and an intermediate bearing, by means of which the shaft element is rotatably mounted about an axis of rotation (L) in the protective tube element, wherein the intermediate bearing comprises an outer ring fixed to the protective tube element and an inner ring fixed to the shaft element, which are rotatable relative to each other, and a clamping mechanism by means of which the inner ring is fixed on the shaft element.

In some examples, an assembly includes a wheel configured to rotate around an axis and a brake system configured to reduce a rotation of the wheel. The brake system includes a disc stack having a rotor disc rotationally coupled to the wheel and a stator disc, wherein the wheel is configured to rotate relative to the stator disc. The brake system includes an actuator configured to compress the disc stack. The brake system is configured to exert a reaction force on the disc stack when the actuator compresses the disc stack. The assembly includes a mechanical stop configured to encounter the brake system, wherein the mechanical stop is configured to limit a linear displacement between the actuator and the disc stack.

A friction clutch includes: a clutch shaft; a clutch housing; a clutch boss; a clutch sleeve; a plurality of first plates supported by a first sleeve portion of the clutch housing; a plurality of second plates supported by a second sleeve portion of the clutch sleeve; a pressure plate; a spring urging the pressure plate toward the first and second plates; and an absorber interposed between the clutch sleeve and the clutch boss. The absorber is disposed in a first direction relative to a second disk portion of the clutch boss and in a second direction, opposite to the first direction, relative to a third disk portion of the clutch sleeve.
