Description

Technical Field

[0001] The utility model relates to the technical field of shock-absorbing pads, in particular to a wear-resistant rubber shock-absorbing pad. Background Art

[0002] The characteristics of rubber shock-absorbing pads are that they have both high elasticity and high viscosity. The elasticity of rubber is generated by the change of its curled molecular conformation. The interaction between rubber molecules will hinder the movement of molecular chains, thus exhibiting the characteristics of viscous damping, so that stress and strain are often in an unbalanced state. Many shaft parts in automobiles are equipped with rubber shock-absorbing pads on the sides.

[0003] In order to improve the service life of rubber shock-absorbing pads, the prior art has made many improvements to shock-absorbing pads, such as the patent with the publication number CN210003723U, which discloses a shock-absorbing pad for automobile shock reduction, including a shock-absorbing pad body, a circular groove is provided on the side of the shock-absorbing pad body, the circular groove runs from one side of the shock-absorbing pad body to the other side, the side of the inner wall of the circular groove is fixedly connected to the side surface of the circular ring, and the two sides of the circular ring are respectively fixedly connected with a first fixing ring and a second fixing ring, the side surface of the first fixing ring is fixedly connected to the side of the inner wall of the circular groove, and the side surface of the second fixing ring is fixedly connected to the side of the inner wall of the circular groove. The utility model is provided with a shock-absorbing pad body, a circular ring, a first fixing ring and a second fixing ring, and the shock-absorbing pad is installed on each support column of the automobile to play a shock-absorbing role, thereby reducing the probability of the shock-absorbing pad being squeezed and cracked.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] The above-mentioned comparative documents need to be pre-installed on the side of the shaft parts of the car when used. When the car is driving, the accessories installed on the shaft parts will cause extrusion and friction on the shock-absorbing pads. Although the rubber shock-absorbing pads in the prior art have wear-resistant effects, they are subjected to friction and extrusion forces for a long time, and the thickness of the shock-absorbing pads will become thinner and thinner. After the shock-absorbing pads are rubbed to a certain thickness, they will lose or reduce their original shock-absorbing effect, and then the shock-absorbing pads need to be replaced. When replacing the shock-absorbing pads, the accessories installed on the shaft parts need to be taken out, which makes it more cumbersome to replace the shock-absorbing pads installed on the sides of the shaft parts. Therefore, there is an urgent need in this field to improve the wear-resistant rubber shock-absorbing pads to solve the defects of the prior art. Utility Model Content
