Damping element having a container tube, a piston mounted with freedom of movement in the damping medium-filled tube, a piston rod connected to the piston, and a fastening part for connecting the damping element to the first of the masses which are to be isolated from each other as effectively as possible with respect to vibration, where the piston rod is connected to the other of the masses. The fastening part includes a shaft and a fork, which serves to connect the fastening part to the first mass, where the fork is permanently connected to the shaft outside the area of the fork which is subject to dynamically alternating loads.

Vibration damper

A vibration damper includes a damping element and a pneumatic spring, where the damping element has a container tube, a fastening part, and a piston rod, and where the pneumatic spring consists of a spring bellows acting as a roll bellows, an outer tube connected to the mass whose vibrations are to be minimized, and a roll-over tube carrying a roll-over profile. The spring bellows forms one boundary of an elastic space filled with a pressurized gas, whereas the roll-over tube seals off the gas space from the container tube and is attached thereto. A stamped and formed support ring, which supports the roll-over tube on the container tube and serves to suppress tilting movements, is installed between the container tube and the roll-over tube.

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.
