The brake master cylinder comprises an elastic part, a cylinder body and a first master cylinder piston, the first master cylinder piston is arranged in the cylinder body, a first hydraulic cavity is formed by the first master cylinder piston and the cylinder body, the first hydraulic cavity is provided with a first hydraulic cavity flow channel opening through which brake fluid flows out of the hydraulic cavity, and the cylinder body is provided with a first end and a second end which are oppositely arranged; the elastic piece and the first hydraulic cavity runner opening are located on the side, close to the second end, of the first main cylinder piston. The brake pedal is actuated through external force, the brake pedal can drive the first main cylinder piston to move from the first end to the second end so as to compress the elastic piece, so that the elastic piece generates feedback force on the brake pedal, brake fluid in the first hydraulic cavity flows out of the first hydraulic cavity through the first hydraulic cavity flow channel opening, and the brake main cylinder integrates the foot feeling simulation function. The number of parts of a braking system can be effectively reduced, and cost is reduced.

    本公开涉及一种制动主缸,包括弹性件、缸体、第一主缸活塞,第一主缸活塞设置在缸体内并与缸体形成第一液压腔,第一液压腔设置有供制动液流出液压腔的第一液压腔流道口,缸体具有相对设置的第一端和第二端,弹性件及第一液压腔流道口位于第一主缸活塞的靠近第二端的一侧;通过外力促动制动踏板,制动踏板能够驱动第一主缸活塞由第一端向第二端运动以压缩弹性件,从而以使弹性件对制动踏板产生回馈力,第一液压腔内的制动液通过第一液压腔流道口流出第一液压腔,制动主缸集成脚感模拟功能,能够有效的较少制动系统零部件,降低成本。
