Caliper body, brake caliper assembly and vehicle brake system

The utility model relates to a caliper body, a brake caliper assembly and a vehicle braking system, the caliper body comprises a caliper body (1) and a piston (2), a working chamber (3) is formed in the caliper body (1), the piston (2) is slidably arranged in the working chamber (3), the caliper body (10) further comprises a piston return mechanism, and the piston return mechanism is arranged in the working chamber (3). And the output end of the piston return mechanism is connected to the piston (2). Through the technical scheme, the caliper body provided by the utility model can effectively solve the problem that the return amount of the piston is reduced due to aging of the rubber sealing ring, and is beneficial to solving the problem of braking dragging of a vehicle. 本公开涉及一种卡钳体、制动钳总成和车辆制动系统，该卡钳体包括卡钳本体(1)和活塞(2)，所述卡钳本体(1)内形成有工作腔室(3)，所述活塞(2)可滑动地设置在所述工作腔室(3)中，所述卡钳体(10)还包括活塞回位机构，所述活塞回位机构的输出端连接于所述活塞(2)。通过上述技术方案，本公开提供的卡钳体能够有效解决因橡胶密封圈老化而引起的活塞回位量减少的问题，有利于解决车辆制动拖滞问题。
