Pneumatic spring for passenger car, has external guide whose inner diameter is smaller than maximum outside diameter of rolling bellow, and shortened, in longitudinal direction of spring, to significant dimension

摘要

The spring has two cross fabric plies with a cord angle of thirty five degrees in a circumferential direction of an elastomer rolling bellow (1). An inner diameter of an external guide (6) is smaller than maximum outside diameter of the rolling bellow by 5 to 15 percentage. The external guide is shortened, in a longitudinal direction of the spring, to a significant dimension.
