An electronic brake actuator for service braking and parking braking comprises a caliper main cylinder, a planetary gear mechanism, a parking braking assembly and a service braking assembly, and a first cambered surface is arranged on the front surface of the caliper main cylinder; the parking braking assembly comprises a lead screw and a nut, the lead screw penetrates through the caliper main cylinder and is connected with the planetary gear mechanism, and the planetary gear mechanism drives the lead screw to be rotatably arranged in a cavity of the caliper main cylinder; the nut is arranged on the lead screw in a sleeving mode and moves in the axial direction of the lead screw, and the nut and the caliper main cylinder are locked through a guide mechanism. The service braking assembly comprises a rotating piece and a ball, and the front side of the rotating piece is connected with the planetary gear mechanism; according to the parking braking device, the lead screw driven by the planetary gear mechanism is used for adjusting the gap between the discs and plays a role in braking, the balls and the ramp which are matched with each other are used for braking in the traveling braking process, and therefore the traveling braking and the parking braking are achieved through the simple structure.

    一种用于行车制动和驻车制动的电子制动执行器,包括卡钳主缸、行星齿轮机构、驻车制动组件和行车制动组件,卡钳主缸的前表面设置有第一弧面;驻车制动组件包括丝杆和螺母,丝杆贯穿卡钳主缸与行星齿轮机构连接,行星齿轮机构驱动丝杆可转动地设置在卡钳主缸的空腔内;螺母套设在丝杆上并沿着丝杆轴向运动,螺母与卡钳主缸通过导向机构锁定;行车制动组件包括旋转件和滚珠,旋转件的前侧与行星齿轮机构连接;本发明驻车制动使用与行星齿轮机构驱动的丝杆调整盘片间隙并起到制动作用,行车制动由相互配合的滚珠和坡道进行制动,从而通过简单的结构兼具了行车制动和驻车制动。
