The invention relates to a suspension strut for wheel suspensions of motor vehicles, having a telescoping shock absorber (12) supported on the chassis of the motor vehicle on one side, and on the wheel guide element (20) on the other side, having a suspension spring (14) disposed about the shock absorber (12), and a stored-energy spring (16) connected in series and configured as compression coil springs and both acting on an adjusting spring plate (34) in opposite force directions, and further having an electric motor-driven actuator (22) disposed within the suspension spring (14) and the stored-energy spring (16), by means of which the adjusting spring plate (34) can be axially displaced, and having at least one ring-shaped bellows enclosing the suspension spring (14) and/or stored-energy spring (16) and connected to the spring plates thereof. According to the invention, the bellows (52) is configured as an overload spring element supporting the suspension spring (14) and/or the stored-energy spring (16). |
