The invention relates to a brake master cylinder, a brake assembly and a vehicle, the brake master cylinder comprises a cylinder body, a piston and a displacement sensor, the piston extends into the cylinder body and is slidably connected with the cylinder body, the displacement sensor comprises a displacement generator and a displacement receiver, the displacement generator is fixed in the piston and is used for transmitting signals, the displacement receiver is fixed relative to the cylinder body, and the displacement receiver is used for receiving the signals. And the sensor is used for receiving signals of the displacement generator to detect the sliding displacement of the piston relative to the cylinder body. The displacement generator in the displacement sensor is directly fixed in the piston, so that the design of an additional connection structure between the displacement generator and the cylinder body can be omitted, the matching error can be reduced, the displacement between the piston and the displacement generator is favorably limited, the displacement generator is prevented from shaking, and the reliability of the displacement sensor is improved. Therefore, the uniformity of multiple emission signals of the displacement generator in the reciprocating motion process of the piston is ensured, and the detection precision of the displacement sensor is improved. In addition, the displacement generator is contained in the piston, so that the space layout of the brake master cylinder is facilitated.

    本申请涉及一种制动主缸、制动总成和车辆,该制动主缸包括:缸体、活塞和位移传感器,活塞伸入缸体内并与缸体滑动连接,位移传感器包括位移发生器和位移接收器,位移发生器固定于活塞内,并用于发射信号,位移接收器相对缸体固定,并用于接收位移发生器的信号,以检测活塞相对缸体滑动的位移。本申请通过将位移传感器中的位移发生器直接固定于活塞内部,可以省去位移发生器与缸体之间的附加连接结构的设计,可以降低配合误差,并有利于限定活塞与位移发生器之间的位移,避免位移发生器晃动,从而保证活塞往复运动过程中,位移发生器多次发射信号的均一性,提高位移传感器的检测精度。此外,将位移发生器收容于活塞内还有利于制动主缸的空间布局。
