Abstract
The suspension element comprises an arm (1) through which extends a wheel stub-axle (2) of the vehicle which is rotatively mounted on a fixed part (3) integral with the chassis of the vehicle with interposition of bearing means between the fixed part (3) and the arm (1), a hydraulic chamber (5) being provided in the arm (1) and containing a slidable piston (7) on which is pivotally mounted a link (8) whose end opposed to the piston (7) is pivotally mounted on the fixed part (3). The bearing means comprise a bearing bush (23) surrounding the fixed part (3) and internally coated with a material for a high resistance dry sliding, the bush (23) being apertured for allowing the arm (1) to oscillate on each side of a lug (13) of the fixed part (3) which radially projects from the bush (23) and is pivotally mounted on the link (8).
