Brake assembly for e.g. pure electric vehicle, has brake pedal decoupled from transmission device in operating mode and coupled with device in another operating mode, and valve closed for former mode and opened for latter mode

摘要

The assembly has a pedal simulator including a compression chamber (16) and a reduction device (17) for reducing space volume of the chamber due to brake pedal actuation. The chamber is coupled with external environment and locked against the environment by a controllable valve (28). A brake pedal cooperates with the simulator, and is decoupled from a power transmission device in operating mode. The pedal is coupled with the transmission device, and deactivates the simulator in another operating mode. The valve is closed for the former mode and opened for the latter mode.
