| 摘要 |
The invention relates to a wheel brake (5) of a hydraulic vehicle brake system having a friction brake pad (13) that is moveable in a pivoting direction of a brake body (14), said brake pad being supported on an auxiliary piston (16), which communicates with a reinforcing piston (10) of a main brake cylinder (2). Upon actuation of the vehicle brake system (1) the support of the friction brake pad (13) provides a hydraulic pressure on the auxiliary piston (16), which acts upon the reinforcing piston (10) of the main brake cylinder (2) in the sense of a brake actuation, e.g. which increases the braking force. It is sufficient to configure one wheel brake (5) with an auxiliary piston (16); the remaining wheel brakes (4) may be of conventional construction. The invention further provides an electromechanical power brake (19). |
