Vehicle shock absorber bushing

Abstract

The invention discloses a vehicle shock absorber bushing. The vehicle shock absorber bushing comprises an inner tube, an outer tube and a rubber sleeve layer, wherein the inner wall of the rubber sleeve layer wraps and is attached to the outer surface of the inner tube; a bump part is arranged on the middle part of the rubber sleeve layer; the outer tube is positioned outside the bump part; a concave part is arranged on the bump part; and a convex part which is in contact with the concave part is arranged on the inner wall of the outer tube. According to the vehicle shock absorber bushing disclosed by the invention, the thickness of the middle part of the outer tube made of a magnesium alloy material is increased, so that the clearance between the thickness of the middle part of the outer tube made of the magnesium alloy material and the inner tube is reduced, and therefore, shaking during travelling of a vehicle is reduced; clearance between the thickness of the end part of the outer tube made of the magnesium alloy material and the inner tube is a bit greater than the middle part, so that collision of the outer tube and the inner tube when the vehicle travels in a twisting mode is reduced; and meanwhile, bonding of the inner tube and the outer tube is facilitated, so that bonding strength is improved by 30% or more. The vehicle shock absorber bushing has the advantages of good vibration damping performance, good radiation and a long service life cycle.

Description

technical field [0001] The invention belongs to the field of automobile vibration reduction and noise reduction, in particular to an automobile shock absorber bushing. Background technique [0002] Automobile shock absorber bushings, also known as automobile suspension shock absorber bushings, and engine suspension shock absorbers, steering gear shock absorbers, shock absorbers, shock absorbers, shock absorbers and other components, They are all part of the car's shock absorption system. After the car is started, whether it is initially idling or driving at high speed, vibration will be generated due to the friction between the tire and the road surface, road bumps, etc., especially when the car engine itself is running. Vibration will form a vibration source , thus causing noise, these vibrations will reduce the service life of auto parts, and have a great impact on driving controllability, riding comfort and vehicle safety, so automotive vibration reduction technology has ...

AI Technical Summary

Problems solved by technology

[0003] The traditional automobile vibration reduction technology uses elastic deformation of rubber to absorb part of the vibration energy of the vibration source and transmit it to the vehicle body after vibration isolation, so as to achieve partial vibration reduction and noise reduction. In the process, the elastic deformation of rubber will quickly produce a large number of However, the heat dissipation performance of the rubber itself is poor, especially when the working environment temperature exceeds 80°C, and then subjected to a certain load force, the shock absorber bushing made of old-fashioned rubber materials has poor thermal aging resistance. It will quickly age, and it will be damaged and scrapped after 3 to 4 months of use. It must be replaced. Therefore, the rubber shock absorber bushing becomes a vulnerable and consumable part, and frequent replacement will bring more troubles. , such as increasing the cost of using the car for the car owner, frequent disassembly and assembly of auto parts will also cause hidden dangers in safety. Long life cycle, while ensuring low cost, shock absorber bushing products that can be widely used in all series of models
