Hydraulic shock absorber or spring leg for motor vehicles

A hydraulic shock absorber for motor vehicles, comprising a cylinder and a piston with a piston rod;

• said cylinder containing fluid, said piston traveling back and forth inside said cylinder on an end of said piston rod;
• said piston rod extending through a package of gaskets maintaining said piston rod aligned and sealing said cylinder;
• a projecting-bolt joint, said piston rod being attached to a vehicle wheel assembly by said projecting-bolt joint;
• said joint including an automatic snap-together attachment to said vehicle wheel assembly and resiliently yielding components suppressing impact and vibration by said automatic snap-together attachment;
• said joint having at least one spring snapping into a matching rigid part of said vehicle wheel assembly;
• spacer means associated with said resiliently yielding components and restricting deformation of said resiliently yielding components after installing said components in place, said spacer means maintaining a distance from abutting surfaces of said spacer means for absorbing shocks and vibrations during operation and preventing premature fatigue of predamaged materials due to loads applied during installation.

• said spring being a resilient disk with recesses, said spring having an edge bent into a rim;
• said rim having a first angle around said spring, said first angle being less than an angle of said matching rigid part;
• said spring and said rigid component having contacting surfaces with an anti-noise coating;
• said resiliently yielding components suppressing impact and vibration comprising two compressed rubber elements one above the other axially, said spring being interposed between said two rubber elements;
• said spring being included in said vehicle body and snapping into a matching rigid part of said projecting-bolt joint.
