Semi-axle sleeve for automobile

Abstract

The invention discloses a half-axle sleeve for an automobile. The sleeve comprises a sleeve frame. A bearing ring is mounted at the lower end of the sleeve frame. The periphery of the sleeve frame issleeved in a pressure dividing device. The pressure dividing device comprises a pressure reducing pipe, connecting rods, clamping blocks, springs, fixing rods, limiting rods, rotating shafts and rotating blocks. The connecting rods are arranged at the lower ends of the periphery of the pressure reducing pipe. The clamping blocks are arranged at the lower ends of the connecting rods. The springs are arranged on the two sides of the lower ends of each clamping block. The fixing rods and the rotating blocks are rotationally connected through the rotating shafts. The limiting rods are arranged atthe upper end of one side of the bearing ring. The rotating shafts are arranged at the joints of the fixing rods and the rotating blocks. Through the design of the pressure dividing device, pressure is shared for the semi-axis sleeve, the pressure of the sleeve is effectively reduced, the problem that the semi-axle sleeve deforms or breaks when subjected to strong pressure is solved, unnecessary accidents caused by a driver are reduced, and the personal safety of the driver is improved.

Description

technical field [0001] The invention belongs to the technical field of spare parts, and in particular relates to a semi-shaft bushing for automobiles. Background technique [0002] Automobile half shaft casing is a high-quality carbon structural steel and alloy structural steel hot-rolled seamless steel pipe for manufacturing automobile half shaft casing and drive axle casing shaft tube. Common grades: 45Mn2, 45, 25MnCr. [0003] However, when the existing automobile half-axle sleeves are in use, the weight of the vehicle body and the reaction force generated by the friction of the wheels are all concentrated on the sleeves. If they are not replaced for a long time, the sleeves will be easily deformed and damaged, which will bring accidents to the driver. Injuries, and the connecting thread may loosen during long-term vibration, causing car failure and increasing maintenance costs.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a semi-axle bushing for automobiles to solve the problem that the weight of the vehicle body itself and the reaction force generated by the friction of the wheels are often concentrated on the bushing when used in the above-mentioned background technology, and it will not be replaced for a long time. It is easy to deform and damage the casing, causing accidental injury to the driver, and the connecting thread may loosen during long-term vibration, resulting in car failure and increasing maintenance costs.
