The invention belongs to an electromechanical braking system in the technical field of vehicles, and discloses a driving and parking braking torque mutual coupling redundancy electromechanical braking system which comprises a brake assembly, an MGU and shell, a driving braking motor and gear reducing mechanism assembly, a gear system bearing support and an ECU controller assembly. The service braking gear reduction mechanism assembly comprises a service braking first-stage reduction gear train mounting mechanism, a second-stage reduction gear train mounting mechanism and a bearing, and the parking braking gear reduction mechanism assembly comprises a parking first-stage reduction worm and gear mechanism, a second-stage reduction worm and gear mechanism and a mounting bearing. The braking torque of the driving braking and the braking torque of the parking braking are mutually coupled, the two systems can share the braking output gear shaft assembly, the driving braking and the parking braking can be independently operated, and meanwhile the parking braking can assist the driving braking when needed. By means of the design, the safety and reliability of the braking system are improved.

    本发明属于车辆技术领域电子机械制动系统,公开了行车和驻车制动力矩相互耦合冗余的电子机械制动系统,包括制动器总成,MGU及壳体,行车制动电机及齿轮减速机构总成,齿轮系统轴承支架,ECU控制器总成,密封盖板以及驻车电机及齿轮减速机构总成,行车制动齿轮减速机构总成包括行车制动一、二级减速齿轮系安装机构及轴承,驻车制动齿轮减速机构总成包括驻车一、二级减速蜗轮蜗杆机构及安装轴承。本发明的行车制动和驻车制动的制动力矩是互相耦合的,两个系统可以共用制动输出齿轮轴组件,行车制动和驻车制动可以独立操作,同时在需要时驻车制动也可以辅助行车制动。这种设计提高了制动系统的安全性和可靠性。
