| 摘要 |
The invention relates to a hydraulic brake (3) for a motor vehicle (1), in which one inlet valve (10) and one outlet valve (11), configured in the switchable fashion, is respectively made available for at least one wheel (2), wherein the inlet valve (10) is fluidly coupled to the outlet valve (11) downstream of the inlet valve (10) via a brake pressure line (12), and wherein a hydraulic accumulator (23) for storing hydraulic fluid (27) is made available downstream of the outlet valve (11). The hydraulic accumulator (23) is to be reaction-free in a recuperative braking mode. The invention provides that the brake pressure line (12) is coupled to a piston (14) of a brake lining (15) of a friction brake (8) of the wheel (2) via a valve arrangement (13), wherein the valve arrangement (13) has a first valve (30) which can open only towards the piston (14), and a second valve (31) which can open only towards the brake pressure line (12), and wherein an opening pressure (34) of the first valve (30) is higher than a residual pressure (29) brought about by the hydraulic accumulator (23). |
