Abstract
A rubber vibration isolator is used as a muffler hanger or muffler mount between a car body and a muffler to hang the latter from the former. The isolator includes a body made of rubber-like elastic material whose damping factor is high, two holes, upper and lower, formed in the center of the body of rubber-like elastic material, and a weight provided between the two holes and supported at opposite sides thereof by rubber-like elastic members. The rubber vibration isolator is advantageous in that coefficients of transfer of vibrations of both high and low frequencies, respectively, are lowered.
Claims3
A rubber vibration isolator adapted for use between a body of a car and a muffler, comprising:
- a unitary body made of rubber-like elastic material having a central area and a high damping factor for suspending the muffler from the car body and dampening low frequency vibrations;
- an upper hole and a lower hole formed in the center of the body of rubber-like elastic material;
- a dynamic damper comprising a metal weight having opposite sides and supported between said upper and lower holes for dampening high frequency vibrations;
- and
- rubber-like elastic members connecting said body of rubber-like elastic material and said opposite sides of said weight for supporting said weight between said upper and lower holes.
