The invention discloses a brake master cylinder for a vehicle, and relates to the technical field of hydraulic braking. Comprising connecting longitudinal rods, a rotating shaft is fixedly connected to the top between the two connecting longitudinal rods, a limiting ring is fixedly connected to the outer wall of the rotating shaft, a rotating structure is rotatably connected to the outer wall of the rotating shaft, a rotating plate is fixedly connected to the bottom of the rotating structure through bolts, and a pedal structure is fixedly connected to the bottom of the rotating plate; and a brake pump is fixedly connected to the left side of the pushing structure, and a liquid guide pipe is arranged on the left side of the brake pump. Through the arrangement of the pedal structure and the rotation assisting structure, when braking is carried out, a driver steps on a pressure pedal in the pedal structure, a pressure sensor detects pressure changes, then an electric push rod in the rotation assisting structure is started to be shortened, a downward rotation force is applied to a rotating plate, and the rotating plate is driven to rotate; therefore, a driver can step on the brake pedal in a more labor-saving manner, and the effects of short brake distance and labor saving are achieved.

    本发明公开了一种车用刹车总泵,涉及液压刹车技术领域。包括连接纵杆,两所述连接纵杆之间顶部固定连接有转动轴,转动轴外壁固定连接有限位环,转动轴外壁转动连接有转动结构,转动结构底部通过螺栓固定连接有转动板,转动板底部固定连接有踏板结构,转动板左侧分别安装有转动助力结构和推动结构,推动结构左侧固定连接有刹车泵,刹车泵左侧设置有导液管。本发明通过踏板结构和转动助力结构的设置,在进行刹车制动时,驾驶员踩在踏板结构中的压力踏板上,压力传感器检测到压力变化,随后启动转动助力结构中的电动推杆缩短,使得转动板受到一个向下转动的力,使得驾驶员踩下制动踏板更为省力,实现了短制动距离与省力兼顾的效果。
