The invention relates to an electromechanical parking brake device, which relates to the technical field of rail transit vehicles, and comprises a shell, a push rod, a lead screw assembly, a spring set, an end cover and a locking assembly, one end of the push rod is located in the shell and slides in the shell, the other end of the push rod penetrates out of the shell, and the end cover is arranged on the side, away from the push rod, of the shell and connected with the shell. The lead screw assembly is arranged in the shell, one end of the lead screw assembly abuts against the push rod, and the other end of the lead screw assembly penetrates out of the end cover and is connected with the locking assembly. The spring set is arranged in the shell, one end of the spring set abuts against the push rod and the lead screw assembly, and the other end of the spring set abuts against the end cover. Electric energy is effectively converted into mechanical energy through rotation of the lead screw assembly, efficient energy storage and release are achieved through energy storage of the compression spring set, brake application of the push rod is efficiently achieved, brake application work does not need to depend on a power source, and safety is high.
本申请涉及一种电机械停放制动装置,其涉及轨道交通车辆技术的领域,其包括壳体、推杆、丝杠组件、弹簧组、端盖与锁止组件;所述推杆的一端位于所述壳体内并在所述壳体内滑移,另一端穿出所述壳体,所述端盖设于所述壳体远离所述推杆的一侧并与所述壳体连接;所述丝杠组件设于所述壳体内,所述丝杠组件的一端与所述推杆抵接,另一端穿出所述端盖并与所述锁止组件连接;所述弹簧组设于所述壳体内,所述弹簧组的一端与所述推杆和所述丝杠组件抵接,另一端与所述端盖抵接。本申请利用丝杠组件的旋转有效地将电能转换为机械能,通过压缩弹簧组蓄能实现高效的能量存储与释放,从而高效实现推杆的制动施加,并且制动施加工作无需依赖电源,安全性高。
