The invention discloses an automobile motor braking device with a multi-stage speed reducer. The automobile motor braking device comprises a driving module, a transmission module and a braking execution module. The motor output of the driving module firstly realizes secondary speed reduction through meshing transmission of all gears, and then realizes planetary gear speed reduction through a planetary gear train arranged at the lower part of a middle body; according to the braking execution module, a ball screw transmission mechanism is arranged on the upper portion in the middle, a planet wheel support is fixedly connected with a ball screw, a piston block is fixedly connected to a screw nut, and the ball screw and the screw nut convert transmitted torque into thrust to push a brake pad to complete braking action. The system is high in response speed and large in output torque, and the risk of hydraulic oil leakage is thoroughly eliminated.
本发明公开了一种携带多级减速器的汽车电机制动装置,包括驱动模块、传动模块和制动执行模块;驱动模块的电机输出首先经由各齿轮啮合传动实现二级减速,再经设置在中间体下部的行星轮系实现行星轮减速;制动执行模块是在中间体内上部设置滚珠丝杠传动机构,行星轮支架与滚珠丝杠固定连接,在丝杠螺母上固定连接活塞块,由滚珠丝杠和丝杠螺母将所传递的扭矩转变为推力,推动刹车片完成刹车动作。本发明响应速度快,输出扭矩大,并彻底消除液压油泄露的风险。
