Axle sleeve shock absorber and vehicle

Abstract

The invention discloses an axle sleeve shock absorber and a vehicle. The axle sleeve shock absorber comprises a rubber axle sleeve body (10), a sealing rubber ring (20) and a metal shell (30), wherein the rubber axle sleeve body comprises an axle hole (11); a ring-shaped groove (12) which extends along the circumferential direction of the rubber axle sleeve body is formed in the peripheral surface of the rubber axle sleeve body; the sealing rubber ring is embedded in the ring-shaped groove so as to limit a ring-shaped channel with the ring-shaped groove; and damping fluid (70) is filled in the ring-shaped channel. The vehicle comprises the axle sleeve shock absorber. Through the technical scheme, when an external connection shaft which is arranged in the axle hole vibrates at low frequency, the axle sleeve shock absorber deforms due to the extrusion from the external connection shaft and load, the damping fluid flows back and forth in the ring-shaped groove, and the damping fluid generates friction with the wall surface of the ring-shaped groove and the inner circumferential surface of the sealing rubber ring to convert the kinetic energy into heat, so that the vibration energy is dissipated and the function of absorbing the shock in a low and medium frequency range is realized.

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...
