Multi-piston disengagement system for a brake device of a vehicle, brake device for a vehicle having a multi-piston disengagement system, and transmission arrangement for a vehicle having the brake device

Abstract

A multi-piston disengagement system for a vehicle brake device includes an annular housing with a plurality of housing portions, each of the housing portions having a respective pressure chamber and a respective hydraulic actuation assembly. Each hydraulic actuation assembly has a piston assembly with a hydraulically movable piston arranged to execute an actuation stroke in the axial direction to generate an actuating force for actuating a brake apparatus of the vehicle brake device, and the annular housing is arranged to dissipate the actuating force. The multi-piston disengagement system may have a pressure transmission device with a connecting device and a traction device operatively connected to the connecting device. The actuating force can be introduced into the connecting device and the traction device can be transferred into a pressure position for exerting an axially directed pressure force against a disc pack arrangement of the brake apparatus during the actuating stroke.
