Abstract
A shock absorber includes a damping element and an air spring, the damping element having a container tube, a fixing part and a piston rod. The air spring has a spring bellows acting as a rolling bellows, an outer tube connected to a mass to be held with little oscillation, and a rolling tube bearing a rolling profile. The spring bellows bounds a gas chamber provided with a gas filling under pressure, while the rolling tube seals off the gas chamber with respect to the container tube and is fixed to the latter in the axial direction. Between the container tube and the rolling tube there is arranged a compression stop cap having three webs and thickened ends, which serve as a stop on the container tube for the rolling tube and to dissipate the radial force component acting on the latter.
