摘要：A parking brake for a railway vehicle includes a pneumatic cylinder having a cylinder wall, a first wall opposite a second wall, and a piston movable within the pneumatic cylinder. At least one spring extends between the piston and the second wall for biasing the piston against the first wall. A gear box is fixed relative to the second wall and includes a hand wheel. A spindle is operatively connected to the gear box to affect movement of a manual reset mechanism having a threaded shaft and a ball screw nut rotatably engaged with the threaded shaft. A pushrod is connected to the manual reset mechanism and extends through the cylinder and the first wall. When the hand wheel is rotated, the manual reset mechanism is rotated to cause the pushrod to move relative to the piston corresponding to the direction of the rotation of the hand wheel.
