Telescopic damper element for motor vehicle - makes use of linear ball bearings to reduce sliding friction

摘要

Spring or damper element is for a motor vehicle having a telescopic shock absorber. The piston rod (2) carrying the damper piston is supported in a piston rod guide (7) which seals the cylinder cavity. The piston rod guide has at least three linear ball bearings (8) uniformly distributed along the rod circumference, with balls (9) circulating in a closed path. USE/ADVANTAGE - Damping system for vehicle suspension which gives a more comfortable ride and reduces the effects of sliding friction.
