Spring element for the wheel suspension of a motor vehicle

摘要

A spring element (2) for the wheel suspension of a motor vehicle has a floating piston (6) in a housing (4), which piston separates a hydraulic chamber (5) from a first gas chamber (7). The hydraulic chamber (5) is connected by way of a line (15) to a hydraulic pump (1) and by way of a line (14) to the hydraulic cylinder (12'') of the damper (12) of a spring strut (3). In order to be able to adjust the dynamic spring constant, a second gas chamber (8) is provided, which can be connected to the first gas chamber (7) by a shut-off element (10). <IMAGE>
