The invention discloses a brake release device and a railway vehicle. The brake release device comprises a shell, a driving mechanism and a pull rope assembly. The pull rope assembly comprises a pull rope and a stroke acceleration unit, the driving mechanism drives the pull rope to move through the stroke acceleration unit, and the stroke acceleration unit can release driving force to enable the pull rope to move in an accelerated mode. The travel acceleration unit is arranged to be matched with the pull rope, driving force can be released in the pull rope pulling process, the driving force can accelerate movement of the pull rope, and therefore the ratchet wheel locking claw can be separated from the ratchet wheel more quickly, and the problem that teeth are hit by the ratchet wheel locking claw and the ratchet wheel is avoided.

    本发明公开了制动缓解装置及轨道车辆,制动缓解装置包括:壳体、驱动机构和拉绳组件;所述拉绳组件包括拉绳和行程加速单元,所述驱动机构通过所述行程加速单元带动所述拉绳移动,所述行程加速单元可释放驱动力以使所述拉绳加速移动。本发明通过行程加速单元的设置与拉绳配合,在拉绳拉动过程中能够释放驱动力,该驱动力能够加速拉绳移动,从而使棘轮止动爪更快速的脱离棘轮,从而避免棘轮止动爪与棘轮产生打齿的问题出现。
