Membrane for vehicle brake cylinders - has elastomer supports in area of mechanical strain to avoid excessive wear

摘要

The membrane for a brake cylinder has an elastomer support (15, 19) vulcanised onto the basic material of the membrane in the area of increased strain. In the event of a continuous membrane in the operating brake part of a combined operating brake and spring accumulator brake cylinder, the elastomer support is vulcanised on the membrane on the centre area which is impinged by the pressure member 813) of the spring accumulator brake cylinder. The elastomer support can be disc shaped or ring shaped. ADVANTAGE - The membrane has sufficient deformability but good rolling properties.
