The invention provides an electronic mechanical brake device for a railway vehicle, and solves the problem that an existing brake is large in size and low in output efficiency. The device comprises a driving motor, a fixing sleeve, a planetary roller mechanism, a front shell, an output shaft and a clutch lock locking mechanism, wherein the front shell is connected with the fixing sleeve to form a cavity; the planetary roller mechanism comprises an input shaft, two positioning rings, a roller frame and a plurality of planetary rollers; the input shaft is arranged in the cavity, the rear end extends out of the cavity, and the front end is provided with an external thread or an annular groove; the roller frame is arranged between the fixing sleeve and the input shaft; the two positioning rings are axially limited at the two ends of the roller frame; the plurality of planetary rollers are arranged on the two positioning rings; the output shaft is arranged in the cavity, and the front end extends out of the cavity; the output shaft can realize non-rotating forward and backward movement in the axial direction; the driving motor is used for driving the input shaft to rotate and driving the N planetary rollers to rotate and revolve, and the planetary rollers drive the output shaft to move front and back in the axial direction of the input shaft; and the clutch lock locking mechanism is used for separating and locking the input shaft.
本发明提供一种轨道车辆用电子机械制动装置,解决现有制动器尺寸较大、输出效率较低的问题。该装置包括驱动电机、固定套筒、行星滚柱机构、前壳体、输出轴和离合锁锁止机构;前壳体与固定套筒连接形成腔体;行星滚柱机构包括输入轴、两个定位环、辊架及多个行星辊;输入轴设在腔体内,其后端伸出腔体,前端设有外螺纹或环形槽;辊架设在固定套筒和输入轴之间;两个定位环被轴向限位于辊架两端;多个行星辊设在两个定位环上;输出轴设在腔体内,前端伸出腔体;输出轴可实现非旋转轴向前后移动;驱动电机用于驱动输入轴转动,带动N个行星辊自转并公转,行星辊驱动输出轴沿输入轴轴向前后移动;离合锁锁止机构用于输入轴分离和锁止。
