Example Embodiment

[0016] figure 1 It is a schematic diagram of the structure of the present invention, figure 2 for figure 1 A-A direction view, as shown in the figure: the small automobile shock absorber of this embodiment includes a positioning mandrel 1 and a shock absorbing sleeve assembly that is sleeved on the positioning mandrel 1, and the shock absorbing sleeve assembly at least includes an outer sleeve The tube 4 and the rubber sleeve 2 vulcanized and molded in the outer sleeve 4; the rubber has a wide range of adaptable stiffness, is not sensitive to stress concentration or surface defects, and has small damping and less energy absorption, thereby ensuring that the shock absorbing sleeve assembly It has a large torsion angle, a strong ability to bear radial loads, improves the radial shock absorption effect, and improves better cushioning performance for small cars. At the same time, the rubber also has excellent fatigue resistance, which can strengthen the shock absorber sleeve Th...

Abstract

The invention discloses a small vehicle shock absorber. The small vehicle shock absorber comprises a positioning mandrel, and a shock absorption sleeve assembly coating the positioning mandrel, wherein the shock absorption sleeve assembly at least comprises an outer sleeve and a rubber sleeve vulcanized in the outer sleeve, and further comprises a wear resistant sleeve having a self-lubricating effect; the wear resistant sleeve and the rubber sleeve are vulcanized as a whole; the positioning mandrel is formed to an annular step; the end part, corresponding to the annular step, of the rubber sleeve is outwards bent in the radial direction to form an annular shock absorption boss; the annular shock absorption boss is vulcanized at one end of the outer sleeve; the vulcanized shock absorption sleeve has good integrity, guarantees the structure stability, and can satisfy the working demands under various bad environments of high temperature and bitter cold; the rubber sleeve can guarantee greater torsional angle of the shock absorption sleeve assembly and stronger capacity of bearing the radial load; and meanwhile, the rubber has excellent fatigue resistance, can improve the fatigue resistance of the shock absorption sleeve assembly, and prolongs the service life thereof.

Description

technical field [0001] The invention relates to small automobile components, in particular to a small automobile shock absorber. Background technique [0002] Shock absorber is the general term for all force transmission and damping devices between the frame of the car and the axle or wheels. impact force, and attenuate the vibration caused by it, so as to ensure the smooth running of the car. Small cars include shock absorbers, cross-arm assemblies, and shock absorbers connected to the cross-arm assemblies. The cushioning performance of the suspension system is mainly achieved through the shock absorbers. The design of the cushioning performance of the shock absorber is ignored. [0003] The shock absorber includes a positioning mandrel and a shock absorbing sleeve that is overlaid on the positioning mandrel. In the prior art, the shock absorbing sleeve is generally made of rigid material stamping, which not only has low strength to bear stress concentration and radial lo...
