ABSTRACT:
A spring support is disposed about and fixed to a shock-absorbing unit and engages the lower end of a coil spring. A spring base engages the upper end of the coil spring and engages a mounting plate which is secured to the vehicle body and is also fixedly connected to the upper end of the shock absorber rod. The spring base has a cup-shaped cavity in which is disposed an energy-absorbing block of compressible elastomeric urethane-type material for absorbing energy when the shock absorber system bottoms out by the upper end of the shock-absorbing unit engaging the bottom of the elastomeric block. The energy-absorbing block has a peripheral disc portion extending thereabout and clamped between a dust cover and the spring base for securing the block in position. The energy-absorbing block includes a first plate of non-compressible material disposed between its upper face and the bottom of the cup-shaped cavity in the spring base. A second plate is disposed on the bottom face of the energy-absorbing block with a sound-deadening material disposed thereon for compressing the energy-absorbing block upon bottoming out of the system when the cylindrical energy-absorbing unit engages the bottom plate of the energy-absorbing block to compress the block.
