The invention relates to the field of railway vehicles, and particularly discloses an electric tread brake of a railway vehicle, which comprises a guide cylinder, a push rod, a linear driver and a brake block, one end of the push rod is connected to an output shaft of the linear driver, and the other end of the push rod coaxially penetrates through the guide cylinder and then is connected with thebrake block; and the push rod is driven by the output shaft and does linear reciprocating motion along the axial direction of the output shaft. The push rod is directly driven by the linear driver, the overall structural complexity and production cost of the device are reduced, meanwhile, the moving range of the push rod is large, and the actual use requirement can be met.
本发明涉及轨道车辆领域,具体公开了一种轨道车辆电动踏面制动器,包括导向筒、推杆、直线驱动器和制动块,所述推杆的一端连接于直线驱动器的输出轴、另一端同轴穿过导向筒后与制动块连接,所述推杆由输出轴带动并沿输出轴的轴向做直线往复运动。本发明的推杆由直线驱动器直接驱动,降低了装置整体的结构复杂度和生产成本,同时推杆的移动范围较大,可满足实际使用需求。
