A rail vehicle brake unit (200) includes a brake actuator (120), at least one pressing member (211), a gear assembly (220), an electric motor (230), and a backup power unit (123). The brake actuator (120) receives a brake command (cmdB) and generates an electric braking force signal (BF) to the electric motor (230) which in turn acts on the gear assembly (220) to bring the at least one pressing member (211) to a specified position relative to a rotatable member (110) mechanically coupled to at least one wheel (105) of the rail vehicle in order to apply a braking force thereto. During operation of the rail vehicle, the backup power unit (123) receives power (W) from a power line (140) in the rail vehicle and accumulates the received power (W). The backup power unit (123) supplies accumulated power to a control circuit in the brake actuator (120) and the electric motor (230) in the event of a power failure (PF) of the power (W) received in the brake actuator (120).
一种轨道车辆制动单元(200),其包括制动致动器(120)、至少一个按压构件(211)、齿轮组件(220)、电动机(230)和备用电力单元(123)。所述制动致动器(120)接收制动命令(cmdB)并对所述电动机(230)产生电制动力信号(BF),所述电动机继而作用在所述齿轮组件(220)上,以使得所述至少一个按压构件(211)相对于机械地连结到轨道车辆的至少一个车轮(105)的可旋转构件(110)达到指定位置,以便对其施加制动力。在所述轨道车辆的操作期间,所述备用电力单元(123)从所述轨道车辆中的电力线(140)接收电力(W)并蓄积所接收的电力(W)。在所述制动致动器(120)中接收的所述电力(W)发生电力故障(PF)的情况下,所述备用电力单元(123)向所述制动致动器(120)中的控制电路和所述电动机(230)提供所蓄积的电力。
