Abstract
The invention relates to a spring strut for wheel suspension systems of vehicles, having a vibration damper (1) and a helical spring (2) partially surrounding the vibration damper (1), wherein the helical spring (2) is supported via a spring plate (3) on an outer pipe (4) of the vibration damper (1) and the spring plate (3) can be adjusted relative to the outer pipe (4). In order to develop such a spring strut in such a way that the standing height of vehicles with different unladen weights can be adjusted to always be the same by adjusting the spring plate, without the friction between the piston rod and the sealing and guiding assembly being disadvantageously increased, it is proposed in accordance with the invention that the line of application of force (5) of the helical spring (2) forms an acute angle (.alpha.) with the longitudinal axis (6) of the vibration damper (1) and the position of the spring plate (3) can be adjusted in the direction of the line of application of force (5).
