Document Type and Number:
Japanese Patent JP7010531
Kind Code:
B2
Abstract:
A disc hydraulic anti-lock brake and a brake system. The disc hydraulic anti-lock brake comprises a support (400) provided with a first opening (415), a core tube (502), a first passage (406), a second passage (412), a third passage (409) and a brake pad base; a first piston (501) provided in the first opening (415), with a first cavity being communicated with the first passage (406) and a service brake valve, and the first piston (501) being provided with a second opening (504); a second piston (506) provided in the second opening (504), with a second cavity (508) being communicated with the core tube (502), the second passage (412) and a parking brake valve; an elastic member (505) provided between the second piston (506) and the bottom of the second opening (504); a brake release system provided with a pump (315) and an unloading valve (322); a brake disc (900) provided with a counting gear ring and a mounting portion; and an anti-lock system provided with a counting sensor, a motor (309), and a liquid drainage valve (310). A liquid inlet of the liquid drainage valve (310) is communicated with the first cavity by means of the third passage (409). ccoridng to the brake, the support (400) is provided with the first opening(416) and the second opening (417), and the first piston (601) and the second piston (701) are provided in the first opening (416) and the second opening (417), respectively. The brake system can achieve service braking, parking braking and anti-lock braking, and is easy to achieve.
