Background

The torsion rubber core acts on two ends of a torsion bar of a chassis bridge of the heavy-duty automobile to play a role in damping and buffering and guiding and transmitting, the received push-pull force and torsional pendulum force are very large, the torsion rubber core is a vulnerable part, most of the torsion rubber cores are synthesized by a metal ball pin and rubber in a vulcanization mode, and the torsion rubber core used in the current automobile industry has the following defects:

1. when the existing torsion rubber core is assembled, the rubber core needs to be forcibly pressed into the thrust rod shell. Make its rubber warp greatly, easily take off the jump ring, also have at present through the torsion rubber core of equipment production, nevertheless because be the separation type structure, can't guarantee the steadiness of structure.

2. The core is glued to present torsion, mostly is multilayer structure, and the edge is naked, gets into the dust very easily, can increase the frictional force of axle center department after the dust gets into, seriously influences the life that the core was glued to torsion.

We propose a dustproof torsion rubber core to solve the above problems.
