Abstract
A spring-loaded brake cylinder for commercial vehicles includes at least one spring-loaded brake piston that can be actuated by a pre-loaded spring and is supported in a housing. A mechanical emergency release device is provided for the emergency release of the spring-loaded brake cylinder. The emergency release device includes an indicator that has an indicator rod indicating the position of the spring-loaded brake piston. The rod extends through a threaded spindle of the emergency release device and is movable in the axial direction. A stop body is disposed in the region of one end of the indicator rod. The stop body is positively connected to the indicator rod by a detent connection produced by an axial relative movement between the indicator rod and the stop body.
