The invention provides a parking braking device for an electronic mechanical braking system, which comprises a shell, a motor, an electromagnet assembly, a ratchet wheel and a pawl, the motor is fixed on one side surface of the shell, a shaft of the motor penetrates through the shell to the other side surface of the shell, the ratchet wheel is pressed on the shaft of the motor, and the electromagnet assembly is fixed on the other side surface of the shell; one end of the pawl is connected with the electromagnet assembly, the other end of the pawl is rotationally connected with a pawl fixing shaft, and the pawl fixing shaft is pressed on the other side face of the shell. When the vehicle is parked, the electromagnet assembly receives a parking signal instruction and drives the pawl to rotate, so that the pawl and the ratchet wheel are locked, and parking braking is achieved. The product structure of the EMB is further improved, the safety performance of automobile braking is improved, and the competitiveness of the EMB product is greatly improved. The parking braking device is simple in structure and simple in process, and compared with a traditional electromagnetic brake, the parking braking device has the advantage that the production cost is better saved.

    本发明提供了一种用于电子机械制动系统的驻车制动装置,其包括壳体、电机、电磁铁组件、棘轮和棘爪,电机固定在壳体的一侧面,且电机的轴穿过壳体至壳体的另一侧面,棘轮压装在电机的轴上,电磁铁组件固定在壳体的另一侧面上;棘爪的一端部与电磁铁组件连接,另一端部与一棘爪固定轴转动连接,棘爪固定轴压装在壳体的另一侧面;当车辆驻车时,电磁铁组件接收驻车信号指令,驱动棘爪转动,使得棘爪与棘轮锁紧,实现驻车制动。本发明进一步完善了EMB的产品结构,提升了汽车制动的安全性能,对EMB产品的竞争力有较大的提升。所述驻车制动装置结构简单,工艺简洁,与传统的电磁制动器相比,更好的节约了生产成本。
