Abstract:
A pneumatic spring brake chamber for a vehicle having a caging bolt assembly according to the present invention has: a head housing; a bottom housing; an adaptor housing provided between the head housing and the bottom housing; a piston disposed between the head housing and the adaptor housing; a hollow actuator rod coupled to the piston and passing through a through hole of the adaptor housing; and a caging nut driven via the actuator rod by the rotation of a caging bolt, disposed along the through hole of the adaptor housing, and coupled to the end of the caging bolt. The caging bolt assembly comprises: a caging bolt body having the head of the caging bolt formed on the upper end; an indicator coupled by passing through the inside of the caging bolt body in the axial direction; a nut stopper coupled to the end of the indicator; the caging nut screw-coupled to the outer peripheral surface of the caging bolt body; and a resilient body disposed between the indicator and the caging bolt body. In order to prevent separation of the caging nut which vertically moves in accordance with the rotation of the caging bolt inside the actuator rod, the nut stopper is coupled to the end of the indicator disposed so as to pass through the caging bolt, to prevent the caging nut from falling off.
