Abstract
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.
