Brake assembly for hydraulic motor car, has changing element provided in master brake cylinder for changing displacable pressure medium volume along shift path of piston, where cylinder is displaceable in housing along actuation direction

摘要

The assembly has a master brake cylinder (1) for housing (2), where the master brake cylinder is linearly displaceable in the housing along actuation direction (B). A piston (4) is actuated in the housing through a brake pedal (3), and comprises hydraulic effective area for displacing pressure medium into a pressure chamber (5) such that a braking pressure structure is operated. A changing element is provided in the master brake cylinder for changing displacable pressure medium volume along a shift path of the piston.
