Abstract: A shock absorber for a wheel suspension of a vehicle may include an outer cylinder, an outer piston that is axially displaceably guided in the outer cylinder, an inner piston that is axially displaceably guided in the outer piston, and a piston rod that is connected to the inner piston and that is guided out of the outer piston. A surface, which is located remote from the piston rod, of a piston portion of the outer piston, which is axially displaceably guided on an inner lateral surface of the outer cylinder, is connected so as to communicate partially with surroundings of the shock absorber.

Abstract: An elastomer bearing has an inner part, an outer sleeve that surrounds the inner part, and an elastomer body that is arranged between the inner part and the outer sleeve. The elastomer body extends from the inner part as far as the outer sleeve. The elastomer body comprises two liquid chambers, which are filled with a liquid and arranged one on top of the other in an axial direction, and a duct carrier arranged radially between the elastomer body and the outer sleeve. The duct carrier surrounds the elastomer body in a region of the liquid chambers and bounds the chambers. The elastomer body is vulcanized to the inner part. To reinforce the elastomer body, two, annular reinforcement inlays are embedded in the elastomer body, and form parts, separate from one another, of a cage that is embedded in the elastomer body.

Abstract: A folding bellows for protecting an interior of the folding bellows effectively from environmental influences and managing pressure changes in the interior. The folding bellows having a gas-tight casing including a plurality of folds in an axial direction. Opposed front faces adjoining the casing. The front faces closed in a gas-tight manner. The casing having a wide region and a narrow region each formed of a plurality of folds with the outer cross-sectional surface of the folds in the wide region being larger than those in the narrow region. The folding bellows in one embodiment used with a motor vehicle subassembly.
