Dismounting tool for half-axle hub side universal joint

Abstract

The invention discloses a dismounting tool for a half-axle hub side universal joint. The dismounting tool comprises a hydraulic device I, a hydraulic device II, hydraulic columns, a connecting device I, an L-shaped connecting rod I, a rotary bearing, a handle, a tension spring, a hydraulic device switch, a telescopic hose, a connecting device II, a fixing clip I, a threaded groove, a threaded column, a rotary handle, an anti-skidding clamping board, a fixing clip II, anti-sliding threads and an L-shaped connecting rod II, wherein the hydraulic device I and the hydraulic device II are symmetrically arranged; the hydraulic device I and the hydraulic device II are separately provided with the hydraulic columns; and the hydraulic device I and the hydraulic device II are connected with the handle through the connecting device I. Compared with the prior art, the novel dismounting tool for the half-axle hub side universal joint completely improves manual dismounting into mechanical dismounting, so that the dismounting difficulty of the universal joint is reduced, the occurrence of safety accidents is avoided, the working efficiency of an automobile repairer is improved, and the speciality of the automobile repairer is also reflected.

Description

technical field [0001] The invention relates to an auxiliary device of a transmission element, in particular to a tool for removing universal joints on the hub side of a half shaft. Background technique [0002] The ball cage is also called "constant velocity universal joint" and is an important part of the transmission system of a car. Its function is to transmit the power of the engine from the transmission to the drive wheels to drive the car to drive at high speed. There are many types of constant velocity universal joints used in cars, among which the most widely used are ball cage type constant velocity universal joints and tripod type constant velocity universal joints, which mainly include sliding sleeves, three-way shafts, transmission shafts, star It is composed of the main parts of sleeve, cage and bell shell. Because the constant velocity universal joint transmits heavy driving torque, the load is heavy, the transmission precision is high, the demand is large, a...

AI Technical Summary

Problems solved by technology

[0003] In car repair, it is common to disassemble the hub universal joint, but the mechanical hydraulic fixing between the universal joint and the half shaft is generally very difficult to disassemble. Nowadays, there are no professional tools for disassembling the universal joint. The masters basically use manual disassembly, using hammers and iron rods to disassemble. During the disassembly process, due to the relatively large impact, it is easy to cause damage to the universal joint, and manual use of the hammer is easy to injure yourself or others, causing safety accidents.
