Actuating unit for electrohydraulic brake-by-wire braking system has simulator spring at least partly arranged in chamber formed in piston and separate from pressure chamber

摘要

The device has a pressure sensor operated by an actuating pedal with a pressure chamber (4) and a displacement simulator. The pressure chamber is bounded by a hydraulic piston that interacts with the pedal. The simulator has a simulator spring and a simulator actuating element with a force transfer connection to the pedal. The simulator spring is at least partly arranged in a chamber (48) formed in the piston separate from the pressure chamber
