Motor vehicle electrohydraulic braking system with a brake pressure signaler, is configured so that if the signaler fails, the simulator spring is directly coupled to a piston that acts directly on the main brake cylinder

摘要

Electrohydraulic braking system for a motor vehicle, with a brake pressure signaler, comprises a main brake cylinder and a simulator. A pump has its intake side coupled to a pressure accumulator and its output side connected to a high pressure store. If the brake system fails, the simulator (9) spring (16) is directly coupled to an activating piston (14) that applies a pressure to the main brake cylinder.
