Embodiment

[0015] like figure 1 Shown is an automotive shock absorber dust cover.

[0016] like figure 2 As shown, the dustproof cover body 1 includes an upper end surface 2, the bottom circumference of the upper end surface is provided with a visor 3, the section of the upper end surface 2 is a circular frustum structure, and the center of the upper end surface top of the upper end surface 2 is opened. A circular hole 4 is arranged for the piston rod to pass through.

[0017] After the pressure bearing test, when the angle a between the slope of the upper end surface 2 and the horizontal plane is 25°, the stress bearing effect is the best.

[0018] like image 3 As shown, there are two symmetrical positioning protrusions 5 extending outward from the upper diameter of the dustproof cover body 1 .

[0019] To sum up, the structure of the dustproof cover of the present invention is simple, and the upper end surface 2 is set as a slope structure, which can effectively buffer the stress...

Abstract

The invention discloses a dustproof cover of a vehicle shock absorber. A main body of the dustproof cover comprises an upper end surface, wherein a cap peak is arranged at the bottom periphery of the upper end surface; and the section of the upper end surface is a cone frustum structure. Compared with the prior art, the dustproof cover has the advantages of simple structure, stable use and large-area promotion and application; the section of the upper end surface in the prior art is a step structure, and the step structure can enable the dustproof cover to be twisted and deformed when being suffered from greater stress, but the slope type upper end surface can release the stress to the high cap peak of the dustproof cover.

Description

technical field [0001] The invention relates to the technical field of shock absorbers for automobile accessories, in particular to a dustproof cover for automobile shock absorbers. Background technique [0002] The dust cover is a part of the automobile shock absorber. Its outer end surface is in direct contact with the buffer connector, and its end surface is provided with a circular opening for the piston rod to pass through. [0003] The utility model patent with the patent application number 201220267018.4 discloses a shock absorber dust cover. The upper diameter of the dust cover body extends outwards and is provided with two symmetrical positioning protrusions. The purpose of the positioning protrusions is to weld The piston rod assembly plays an auxiliary positioning role for the dust cover. The end of the dustproof cover of this structure is a stepped structure, which is easily deformed when subjected to a large stress during use. Contents of the invention [00...
