Abstract

Technical Field
[0001] The invention relates to the technical field of rubber pads, in particular to a vehicle rubber pad with expansion and shock absorption function. Background Art
[0002] Cars will experience bumps while driving, especially when the road conditions are bad, and the moving parts of the engine will also vibrate. If the engine is directly connected to the frame, the frame will also vibrate, affecting the car's handling and comfort. Therefore, a shock-absorbing pad should be installed between the car engine and the frame to minimize the transmission of the engine's vibration to the frame. The shock-absorbing pad is usually an integral rubber block. When this type of shock-absorbing pad is impacted by a heavy load, its pressure-bearing capacity is limited. The existing rubber pad cannot achieve a better shock-absorbing effect by expansion, and the shock absorption cannot be adjusted according to the amplitude of the vibration. It is easy to be torn under the alternating action of the vibration and has a low vibration absorption capacity. In view of this, we propose a vehicle rubber pad with expansion shock absorption.
