Title:
VEHICULAR HYDRAULIC BRAKE DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/080929
Kind Code:
A1
Abstract:
A hydraulic circuit (40) in this vehicular hydraulic brake device (100) is provided with the following: an electrical hydraulic-pressure source (41); a reservoir (R); a first supply channel (414) that connects a discharge channel (413) to a resistance-generating hydraulic chamber (C1); a first elimination channel (415) that connects the first supply channel (414) to a return channel (412); a second supply channel (416) that connects the discharge channel (413) to a brake-driving hydraulic chamber (C2); a second elimination channel (417) that connects the second supply channel (416) to the return channel (412); a first on-off valve (V1); a second on-off valve (V2); a third on-off valve (V3); a first check valve (V4); a second check valve (V5); a first control valve (V6); a second control valve (V7); and a pair of pressure sensors (S2 and S3). This makes it possible to reduce the amount of vibration and noise produced by the electrical hydraulic-pressure source and the power consumption thereof.
