Description

Core is glued to durable torsion

Technical Field

The invention belongs to the technical field of automobile chassis, and particularly relates to a durable torsion rubber core.

Background

The torsion rubber core acts on two ends of a torsion bar of the automobile chassis bridge, and plays a role in damping and buffering, guiding and transmitting.

However, the middle part of the middle shaft of the existing torsion rubber core is a spherical part, and along with the extension of the action time of the elastic rubber body under the action of external torsion, the spherical part of the middle shaft is easy to degum, and once the spherical part is degummed, the torsion rubber core also loses the damping effect. Moreover, the existing torsion rubber core can cause the shell to be damaged when being subjected to larger pressure, so that the normal use of the torsion rubber core is influenced, the shell of the rubber core is not tightly connected, the torsion rubber core is easy to wear and has influenced service life, and therefore a durable torsion rubber core is provided for solving the problems.
