A vibration damper for a shock absorber strut is described which is arranged on a piston rod above the elastic body-side bearing facing away from the vehicle wheel. The damper comprises a mass element which is connected with a carrier plate, in which case the element is fastened on a centric pot element by way of radially extending elastic arms, the pot element being held on the free end of the piston rod above the elastic bearing.

Vibration damper for a vehicle wheel shock absorber strut

In a device for damping torsional vibrations of the body of a convertible vehicle, an elastically mounted weight is used. The damper is mounted elastically on a frame of a windshield by slide bearings and at a distance from the frame, relatively free to vibrate in the transverse directions of the vehicle. The damper has a frequency equal to the torsional natural frequency of the vehicle in the area of the frame, with the bearings having a sliding resistance determined by their geometry. The damper is elastically mounted by at least one central slide bearing on the frame element, with the damping weight having a leaf spring element at each end and mounted to abut the frame element and to permit transverse movement of the damping weight.

Device for damping torsional vibrations

For the absorbing of natural frequencies of the vehicle body, a vibration damping supporting strut for a motor vehicle has an axially movable absorber mass in a hollow space of the piston rod extending in the direction of the longitudinal axis. The absorber mass is in each case supported on its ends by way of a spring element arranged in a clearance of the hollow space. These clearances are filled with a medium and are connected with one another by at least one passage in the absorber mass. This construction results in an absorber effect on the natural torsional frequency of the vehicle body in that an absorbing takes place of the high-energy shock portions which have the same frequency and are introduced from the power section by way of the piston rod, whereby the shocks exciting the vehicle body are then largely absorbed.

Vibration damping supporting strut for a motor vehicle

A damper is provided on a convertible for the dampling of bodyside torsional vibrations in the area of the windshield frame. This damper is arranged particularly on the frame of the windshield and is held by way of elastic slide bearings. The damper is arranged in the open at a distance from the frame and can swing relatively freely in the transverse directions of the vehicle so that natural torsional frequencies of the vehicle on the frame are damped.
