Braking system for motor vehicle has arrangement for coupling movements of second and third pistons activated depending on manner of operation of third piston in housing

摘要

The system has a main cylinder (1), a first piston (2) coupled to a brake pedal (3), a second piston (4) that operates the main cylinder, a third piston (5), an elastic element (6) that transfers actuating forces from the pedal to the third piston and forms a pedal displacement simulator for providing feel in "brake0by-wire" mode, a pedal coupling arrangement and an intermediate chamber between the second and third positions. It has an arrangement for coupling the movements of the second and third positions activated depending on the manner of operation of the third piston in the housing.
