The invention relates to a hydraulic brake unit, a brake assembly and a vehicle, the hydraulic brake unit comprises a shell, a brake cylinder piston and a detection assembly, and a signal generator is arranged on the side wall of the brake cylinder piston; according to the hydraulic brake unit, the signal generator is located on the side wall of the brake cylinder piston, the design of an additional connecting structure between the signal generator and the shell can be omitted, the matching error can be reduced, displacement between the brake cylinder piston and the signal generator can be limited, shaking of the signal generator is avoided, and the service life of the hydraulic brake unit is prolonged. Therefore, the uniformity of signals transmitted by the signal generator for multiple times in the reciprocating motion process of the brake cylinder piston is ensured, and the detection precision of the detection assembly is improved. In addition, the signal generator is contained in the brake cylinder piston, so that the spatial layout of the hydraulic brake unit is facilitated.
本申请涉及一种液压制动单元、制动总成及车辆,液压制动单元包括壳体、制动缸活塞及检测组件,通过将信号发生器设置制动缸活塞的侧壁上,相较于相关技术中采用连杆、支架等结构固定活塞及感应元件,本申请实施例所提出的液压制动单元中的信号发生器位于制动缸活塞的侧壁上,可以省去信号发生器与壳体之间的附加连接结构的设计,可以降低配合误差,并有利于限定制动缸活塞与信号发生器之间的位移,避免信号发生器晃动,从而保证制动缸活塞往复运动过程中,信号发生器多次发射信号的均一性,提高检测组件的检测精度。此外,将信号发生器收容于制动缸活塞还有利于本申请中液压制动单元的空间布局。
