Brake actuating unit has individual hydraulic connection, where hydraulic pressure source is connected with amplifying area of amplifying stage and pressurizing medium is provided with master brake cylinder

摘要

The brake actuating unit has a master brake cylinder (1) actuated by a brake pedal (4) and is attached at the brakes (7-10) of a motor vehicle. An amplifying stage (2) is connected upstream of the master brake cylinder. An additive auxiliary force is superimposed to break pedal actuating force. A master brake cylinder piston (22) is operated with the sum of both forces. A controlled hydraulic pressure source (3) is provided for supplying an auxiliary pressure producing the auxiliary force. An individual hydraulic connection (19) is provided.
