ABSTRACT:
A load-carrying, shock absorbing strut is provided comprising an outer tube for carrying a wheel axle journal. There is slidably accommodated in the tube a shock absorber cylinder which is connected with the chassis frame. A downwardly emerging piston rod of the cylinder is fastened to the bottom of the outer tube. Between the shock absorber cylinder and the outer tube there is provided a lubricant annular chamber of constant volume which is closed off above and below by upper and lower guide and sealing rings arranged on the outer tube. A sealing ring is arranged above each guide ring with axially limited play and comprise lubricant-sealing felt rings. To effect good dirt-deflecting action there is present above the upper sealing ring a dirt-deflecting ring which has the dual function of limiting the sealing ring axial play as well as removing dirt from the shock absorber cylinder.
