Abstract
The coil spring of a vehicle shock absorber can be seated on an elastomeric sound isolator pad whose spring engagement surface has plural slot-like depressions evenly spaced around the pad circumference. These slot-like depressions form raised ribs that provide the contact surfaces for the lowermost convolution of the coil spring. Each rib can readily deform under the spring force. Side surfaces of the ribs can act as heat-dissipating surfaces. The slot construction allows the pad to be formed out of a reasonably high durometer and highly wear-resistant elastomer without adversely affecting the desired rib deflection.
