铁路车辆用减振装置
Abstract:
铁路车辆用减振装置(1)具备：致动器(A)，其具有根据工作流体的供给而进行伸缩的缸主体(Cy)、向缸主体(Cy)供给工作流体的泵(12)以及对泵(12)进行驱动的电机(15)，并且，致动器(A)被设置在铁路车辆中；控制部(C)，其对电机(15)进行控制，当应该向电机(15)给予的电流值(I)成为使限制转矩输出的电流阈值(Iα)以上时，控制部(C)使电机(15)停止，所述限制转矩被设定为，超过电机(15)的额定转矩的值。
Abstract(English):

This railcar damping device (1) comprises: an actuator (A) installed to a railcar and including a cylinder body (Cy) that extends and contracts by being supplied with a working fluid, a pump (12) thatsupplies the working fluid to the cylinder body (Cy), and a motor (15) that drives the pump (12); and a control unit (C) that controls the motor (15). The control unit (C) stops the motor (15) when acurrent value (I) to be provided to the motor (15) becomes higher than or equal to a current threshold (I[alpha]) for outputting a limit torque which is set to a value above the rated torque of the motor (15).
