Preparation technology for high-abrasion-resistance automobile spindle

The invention discloses a preparation technology for a high-abrasion-resistance automobile spindle, and relates to the technical field of automobile parts. According to structure assembling, two roundpins are symmetrically inserted into corresponding holes in a square shaft, then, an anti-abrasion sleeve is arranged outside an installing section of an automobile shaft main body in a sleeving mode, meanwhile, the left end of the square shaft is inserted into a square hole of the automobile shaft main body, then, the end, provided with a spring, of a positioning pin is inserted into the squareshaft and pushed inwards to extrude the two round pins to be separated towards the two sides, and the two round pins are inserted into pin holes on the two sides. According to the preparation technology for the high-abrasion-resistance automobile spindle, by arranging the anti-abrasion sleeve outside the automobile shaft main body in a sleeving mode, the anti-abrasion sleeve replaces the automobile shaft main body to be ab
