The invention relates to the technical field of vehicles, and particularly discloses an electronic mechanical braking device and an electronic mechanical braking device control method.The electronic mechanical braking device comprises a shell, a driving unit, an elastic piece and a transmission unit, and the transmission unit comprises a thrust bearing assembly and a transmission assembly; the thrust bearing assembly comprises a driving disc, a driven disc and a plurality of rolling bodies, a plurality of first rolling grooves are formed in one of the driving disc and the driven disc in a concave mode, the first rolling grooves are formed in the circumferential direction of the driving disc at intervals, and the inclination degrees of the first rolling grooves in the circumferential direction of the driving disc are the same. The multiple rolling bodies are arranged in the multiple first rolling grooves in a one-to-one correspondence mode and abut against the driving disc and the driven disc at the same time, the elastic piece enables the driven disc to be close to the driving disc, the driving unit drives the driving disc to rotate, and the driven disc is coaxially and fixedly connected with the threaded rod; the device solves the problems that the friction force between the threaded rod and the nut is increased and the transmission efficiency is reduced through the thrust bearing assembly when the braking force is provided by only depending on the transmission assembly.

    本发明涉及车辆技术领域,具体公开了电子机械式制动装置及电子机械式制动装置控制方法,该电子机械式制动装置包括壳体、驱动单元、弹性件和传动单元,传动单元包括推力轴承组件和传动组件,推力轴承组件包括主动盘、从动盘和多个滚动体,主动盘和从动盘中的一个凹设有多个第一滚槽,多个第一滚槽绕主动盘的周向间隔设置且绕主动盘的周向的倾斜度相同,多个滚动体一一对应设置于多个第一滚槽内且同时与主动盘和从动盘抵接,弹性件使从动盘向主动盘靠近,驱动单元驱动主动盘转动,从动盘与螺纹杆同轴线固接;该装置通过推力轴承组件解决了单纯依靠传动组件提供制动力时,螺纹杆和螺母之间存在摩擦力增大,传递效率降低的问题。
