Shaft shock absorber and vehicle

Abstract

The invention discloses a shaft sleeve shock absorber and a vehicle. The shaft sleeve shock absorber comprises a rubber shaft sleeve body (10), a sealing rubber block (20) and a metal shell (30). The rubber shaft sleeve body is provided with a shaft hole (11), a first groove (12) is formed in the peripheral face of the rubber shaft sleeve body, the sealing rubber block is embedded in the first groove and is separated from the bottom of the first groove to form a closed oil cavity, the oil cavity is filled with damping liquid (60), and an air cavity made of a flexible material is further arranged in the oil cavity; and through the technical scheme, when external loads borne by the shaft sleeve shock absorber are too large, the sealing rubber block moves towards the bottom of the first groove under the effect of the external loads, the volume of the oil cavity becomes small, the air cavity is compressed to deform, air is compressed to generate heat energy, and therefore vibration energy is converted into heat energy to be dissipated.

Description

technical field [0001] The invention relates to the field of axle sleeves, in particular to an axle sleeve shock absorber and a vehicle. Background technique [0002] The vehicle bushings in the prior art are usually made of pure rubber, which leads to a linear stiffness curve without the effect of damping and vibration reduction, and is too rigid during the load transmission process, which is not conducive to the handling stability and comfort of the vehicle design requirements. If the road is too undulating, the vibration will become more serious, resulting in insufficient handling and comfort of the vehicle, and easily causing passenger irritation and traffic injuries. Contents of the invention [0003] The purpose of the present invention is to provide a shaft sleeve shock absorber, which can realize the damping and vibration reduction function while supporting the external connecting shaft. [0004] In order to achieve the above object, the present invention provide...
