Description

Liquid storage cylinder of automobile shock absorber

Technical Field

The utility model belongs to the technical field of the car, concretely relates to automobile shock absorber ware liquid receiver.

Background

In order to accelerate the attenuation of the vibration of a frame and a vehicle body and improve the running smoothness of an automobile, a shock absorber is arranged in a suspension system of most automobiles and used for inhibiting the shock generated when a spring rebounds after absorbing shock and the impact from the road surface, and a liquid storage cylinder is an important component in the shock absorber and provides oil storage and supporting functions for the shock absorber.

The transition area of the outer diameter step of the prior liquid storage cylinder is in a 90-degree shape and has the requirement that the radial runout is less than 0.3, and although shaping is carried out after necking (as shown in figures 1 and 2), the radial runout is 0.5MM and seriously out of tolerance because the deformation area of the necking is too short and stress distribution is concentrated.

SUMMERY OF THE UTILITY MODEL

In order to overcome the above-mentioned defects of the prior art, the present invention provides a liquid storage cylinder for a shock absorber of an automobile.

In order to realize the utility model discloses an aim, the technical scheme who adopts is:

a liquid reservoir for a shock absorber of an automobile, comprising:

the diameter of the first cylinder body is smaller than that of the second cylinder body, the first cylinder body is connected with the second cylinder body through a conical transition cylinder, a first connecting end of the conical transition cylinder is connected with the first cylinder body, and the diameter of the cross section of the first connecting end is the same as that of the first cylinder body; and the second connecting end of the conical transition cylinder is connected with the second cylinder body, and the diameter of the cross section of the second connecting end is the same as that of the second cylinder body.

In a preferred embodiment of the present invention, the liquid storage cylinder of the automobile shock absorber has a runout of 0.2.

The beneficial effects of the utility model reside in that:

the utility model discloses a structure makes throat deformation zone extension, makes stress distribution even, and the runout obtains very big improvement to, reduce the plastic process, reduced the processing cost.

Detailed Description

As shown in FIGS. 1 and 2, a liquid reservoir 1 for a shock absorber of an automobile shown in FIG. 1 has a 90 DEG shape at a stepped transition 2 of an outer diameter. However, in actual processing, the requirement that the radial runout is less than 0.3 exists, so the prior art processing mode is to use the liquid storage cylinder 1 of the automobile shock absorber shown in the figure 1 after necking.

As shown in figure 2, after necking, although the convex groove 3 is formed by shaping the transition region 2 of the outer diameter step of the liquid storage cylinder 1 of the automobile shock absorber, the radial runout is 0.5MM and is seriously out of tolerance because the deformation region of the necking is too short and the stress distribution is concentrated.

In order to overcome the problems of the prior art without additional increase of the manufacturing cost, the inventor has conceived of designing a liquid reservoir for a shock absorber of an automobile in the following structure.

As shown in fig. 3, the liquid storage cylinder 100 for the shock absorber of the automobile comprises a cylinder body 110 and a cylinder body 120, wherein the diameter 110a of the cylinder body 110 is smaller than the diameter 120a of the cylinder body 120, in order to avoid serious radial run-out tolerance caused by stress concentration, the cylinder body 110 and the cylinder body 120 are connected through a cone transition cylinder 130, a connecting end 131 of the cone transition cylinder 130 is connected with the tail end 111 of the cylinder body 110, and the cross-sectional diameter 131a of the connecting end 131 is the same as the diameter 110a of the cylinder body 110; the connecting end 132 of the tapered transition cylinder 130 is connected to the head end 121 of the cylinder body 120, and the cross-sectional diameter 132a of the connecting end 132 is the same as the diameter 120a of the cylinder body 120. Due to the structure, the radial run-out of the automobile shock absorber liquid storage cylinder 100 is 0.2, and an additional shaping step is not needed after necking, so that an automobile shock absorber liquid storage cylinder product meeting the specification can be obtained.
