Problems solved by technology

[0006] One of the purposes of the present invention is to provide a bottom valve seat that can automatically position the bottom valve body of the shock absorber in the bottom valve seat. The seat solves the long-standing problem of unstable positioning of the bottom valve body of the shock absorber on the bottom valve seat, making the production of the shock absorber more stable and consistent, and also solves the problem of abnormal noise, large friction and Potential failure modes for severe flank wear

Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] Such as Figure 5 As shown, the shock absorber includes a bottom valve seat 1 , a bottom valve body 2 and an oil storage cylinder 5 .

[0024] Such as Figure 4 As shown, the bottom valve seat 1 includes a first conical surface 31, a second conical surface 32, a first step 41 and a second step 42, and the first step 41 and the second step 42 are respectively arranged on the first conical surface. 31 and 32 on the second conical surface.

[0025] The bottom valve seat 1 is a sheet metal part, and the first tapered surface 31, the second tapered surface 32, the first layer of steps 41 and the second layer of steps 42 are on the same axis.

[0026] In order to ensure the coaxiality of the first conical surface 31, the second conical surface 32, the first step 41 and the second step 42, when the bottom valve seat 1 is manufactured, it is necessary to draw out the exce...

Abstract

The invention discloses a bottom valve base allowing automatic positioning of a shock absorber bottom valve body inside the bottom valve base and relates to an automotive shock absorber part. The bottom valve base allowing automatic positioning of the shock absorber bottom valve body inside the bottom valve comprises a first conical surface, a second conical surface and double layer steps, wherein the double layer steps are arranged on the first conical surface and the second conical surface. Compared with the prior art, the bottom valve base allowing automatic positioning of the shock absorber bottom valve body inside the bottom valve base has the advantages of solving the problem that positioning of the shock absorber bottom valve body on the bottom valve base is not stable for a long time, enabling shock absorber production to be stable and good in uniformity and meanwhile solving the potential failure mode that the shock absorber has abnormal sound and is large in frictional force and serious in lateral side abrasion.

Description

technical field [0001] The invention relates to an automobile shock absorber part, in particular to a bottom valve seat capable of automatically positioning the bottom valve body of the shock absorber in the bottom valve seat. Background technique [0002] How to position the bottom valve body in the bottom valve seat of the shock absorber has always been a difficult point in the design and production process of the shock absorber. It has potential failure modes for the shock absorber such as abnormal noise, high friction and serious side wear , There has been no effective way to solve it; its traditional bottom valve body and bottom valve seat positioning have three structures. [0003] The first kind is attached figure 1 As shown, the sheet metal part of the bottom valve seat 1 is drawn into a bowl shape, and then the bottom valve body 2 is put into the bottom valve seat 1, and the bottom valve body 2 and the tapered surface of the bottom valve seat 1 are used for positio...
