Abstract

During a shock absorbing movement a rolling crease of a roll bellows is supported at the outer mantle surface of a wall of a pot-shaped rolling piston in an arrangement for a roll bellows-type pneumatic shock absorber. In order to provide a rolling piston with a high stiffness and a low total weight the wall is provided with stiffening corrugations which are essentially extending in a longitudinal direction of the rolling piston. Due to the stiffening corrugations high loads exerted by the rolling crease and any maximum load peaks occurring during the dynamic operation of the pneumatic shock absorber may be securely received and compensated by the rolling piston.
