Abstract
A friction brake for a vehicle power shift transmission is disclosed. The friction brake includes a load gear that is rotatably driveable about a centre longitudinal. A friction braking device is provided for decelerating and/or fixing the load gear. An actuating device for actuating the friction braking device, the actuating device includes an moveable spreading piston. The moveable spreading piston while performing a spread along the centre longitudinal axis automatically materialising as a function of a load torque provided on the load gear, provides a braking force for actuating the friction braking device.

A friction brake for a vehicle power shift transmission, comprising:
- a load gear that is rotatably driveable about a centre longitudinal axis;
- a friction braking device for decelerating and/or fixing the load gear;
- an actuating device for actuating the friction braking device, the actuating device includes an moveable spreading piston;
- wherein the moveable spreading piston while performing a spread along the centre longitudinal axis automatically materialising as a function of a load torque provided on the load gear, provides a braking force for actuating the friction braking device.
A vehicle power shift transmission of a vehicle that is driveable by motor power and/or pedal power, comprising:
- at least one friction brake, the at least one friction brake including:
- a load gear that is rotatably driveable about a centre longitudinal axis;
- a friction braking device for decelerating and/or fixing the load gear;
- an actuating device for actuating the friction braking device, the actuating device includes an moveable spreading piston that is adjustable axially with respect to the centre longitudinal axis;
- wherein the moveable spreading piston, while performing a spread along the centre longitudinal axis that materializes automatically as a function of a load torque provided on the load gear, provides a braking force for actuating the friction braking device;
- wherein the at least one friction brake is directly or indirectly coupled to at least one of a ring gear, a planet gear, and a sun gear of the vehicle power shift transmission.
