Document Type and Number:
Japanese Patent JP3637058
Kind Code:

Abstract:
A spring brake actuator, formed by a housing having an elastomeric diaphragm dividing the interior into two chambers, comprises a pressure plate adjacent the diaphragm in one of the chambers with a large force compression spring between the pressure plate and the housing. A hollow actuator rod is mounted within the chamber for reciprocal movement with the diaphragm and the pressure plate and receives a permanently installed caging tool extending through a housing aperture, a pressure plate aperture and into the hollow actuator rod. The pressure plate includes a bearing in the pressure plate aperture to facilitate reciprocal movement of the pressure plate over the caging tool.
