Description

Iron set disassembly tool

The present invention particularly relates to a tool for disassembling and assembling iron sleeves.

A torsion bar is usually installed between the vehicle chassis and the wheel axle. The torsion bar can offset the impact generated by the vibration when the vehicle is running on a bumpy road, and reduce the roll of the vehicle when the vehicle is turning, so as to maintain the balance of the vehicle. One of the iron sleeves of the torsion bar are respectively assembled with the automobile chassis and the wheel shaft after long-term stress, which is easy to wear and needs to be replaced.

Conventionally, when replacing the iron sleeve, the constructor knocks the iron sleeve out of the torsion bar by hitting the iron sleeve. However, the direction of force is unstable when the iron sleeve is hit, which easily causes deformation of the iron sleeve and is difficult to remove smoothly. The process of dismantling is laborious and time-consuming.

Therefore, it is necessary to provide a novel and progressive iron sleeve disassembly tool to solve the above-mentioned problems.
