Novel thrust rod assembly

Abstract

The invention relates to a novel thrust rod assembly. The novel thrust rod assembly comprises a first ball seat and a second ball seat. The first ball seat and the second ball seat are of cylinder structures. The first ball seat and the second ball seat are connected through a connecting pipe. The two ends of the connecting pipe gradually become larger in diameter and gradually become larger in wall thickness through upsetting, so that the two ends of the connecting pipe form concave-arc surfaces matched with the outer surfaces of the cylinder structures of the first ball seat and the second ball seat, and finally, form an integrated structure through welding. In the novel thrust rod assembly, the first ball seat and the second ball seat are of the cylinder structures, finish machining ofpipe fittings is directly adopted, forging is not needed, and the cost of materials is decreased by 30% while the quality is ensured; and meanwhile, the welding area of the first ball seat and the second ball seat is also increased by 30%, and the corresponding strength is also increased by 30%. The new structure of the novel thrust rod assembly solves the problems of the excessively large productmass and the excessively high machining cost, the probability of fracture and detachment is decreased, and the lightweight weight reduction need of a thrust rod is also ensured while the strength ofthe thrust rod is ensured.

Description

technical field [0001] The invention relates to auto parts, in particular to a novel thrust rod assembly. Background technique [0002] The thrust rod assembly of auto parts not only needs strong thrust, but also needs to reduce weight while reducing weight. [0003] The invention of 200720140051X relates to a heat-shrinkable and welded thrust rod automobile air suspension device, which includes a steel circular tube-shaped rod body, a ring-shaped cast steel end of unequal thickness, and a rubber hinge assembly. The solid round handle forms a mating section, and is connected to the end by a circular weld at the bevel of the rod body. Its advantages are: not only good manufacturability and economy, but also enhanced safety and reliability in the running process of the automobile. [0004] The patent document is that the rod body forms a matching section with the solid round handle of the end after heat shrinkage, and is connected with the end by an annular weld at the groov...
