Embodiment Construction

[0018] Examples, see figure 1 Shown: the automobile shock absorber piston rod, including the rod body 10. The upper end of the rod body 10 is fixedly connected with a piston, and the lower end is provided with a bracket thread 131 .

[0019] Further speaking:

[0020] The rod body 10 includes an intermediate tube 11 located in the middle, an upper connector 12 whose lower end is connected to the upper end of the intermediate tube 11 , and a lower connector 13 whose upper end is connected to the lower end of the intermediate tube 11 . The piston is fixed on the upper end of the upper connecting member 12 , and the bracket thread 131 is located on the lower outer surface of the lower connecting member 13 . That is to say, the middle part of the rod body 10 is a hollow structure.

[0021] The intermediate pipe 11 is prepared by a finish-rolled hollow steel pipe, and the upper connector 12 and the lower connector 13 are connected to the intermediate pipe 11 by friction welding....

Abstract

The invention discloses a piston rod of an automobile shock absorber, which includes a rod body, the upper end of which is fixedly connected with a piston, and the lower end is provided with a bracket thread, and the rod body includes an intermediate pipe in the middle and an upper connecting piece whose lower end is connected to the upper end of the intermediate pipe The upper end is connected to the lower connecting piece at the lower end of the middle pipe, the piston is fixed on the upper end of the upper connecting piece, and the bracket thread is located on the lower outer surface of the lower connecting piece; the middle pipe is made of a precision-rolled hollow steel pipe, and The upper connecting piece and the lower connecting piece are connected to the middle pipe by friction welding; and, the surface treatment of the outside of the middle pipe includes the following steps in turn: nickel plating of 30-40 μm, and then cutting off 10-15 μm; chrome plating 40-50μm; salt spray treatment for at least 48h, fog grade 10 or above. The invention has the advantages of low cost and safe and reliable use.

Description

technical field [0001] The invention relates to the technical field of motor vehicle accessories, in particular to a piston rod of an automobile shock absorber. Background technique [0002] The shock absorber is one of the most important parts of the car, and the piston rod is one of the most important accessories in the shock absorber. Specifically, the piston rod should have a sufficiently smooth surface or a sufficiently hard surface hardness, and preferably the cost thereof can be reasonably controlled. However, there are not many piston rods on the market that can meet the above conditions at the same time, mainly because the surface hardness and smoothness are often inversely proportional to the cost of the piston rod. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the object of the present invention is to provide a piston rod of an automobile shock absorber, which has the characteristics of low cost and safe and rel...
