Detailed Description

As shown in fig. 1 to 5, a suspension adjusting member structure capable of adjusting the angle of a main spring mainly comprises three parts, namely a pair of main rubber springs 1, an inner tube 2 and an outer tube 3, wherein the main rubber springs 1 are assembled into the suspension main spring in an inserting manner, the inner tube 2 is in interference fit with an inner ring of the suspension main spring, and the outer tube 3 is in interference fit with an outer ring of the suspension main spring; the outer tube 3 is pressed into the suspended exoskeleton.

A pair of rubber main spring 1, inner tube 2 and outer tube 3 are assembled together through grafting interference fit, guarantee the stability of structure in suspension timing process, and need not long-time keeping stable in structure.

The inner pipe 2 and the outer pipe 3 are made of cast metal materials.

A pair of rubber mainsprings 1 are each vulcanized, without being vulcanized into one piece.

The main spring 1 is composed of an outer insertion piece 11, an inner insertion piece 12 and a rubber main spring 13, wherein the inner insertion piece 12 is located on the inner side of the rubber main spring 13, the outer insertion piece 12 is located on the outer side of the rubber main spring 13, and the outer insertion piece 11, the inner insertion piece 12 and the rubber main spring 13 are vulcanized into a whole.

When the angle of the suspension main spring needs to be adjusted, only a pair of main springs 1 needs to be disassembled and assembled according to the required angle, and the rigidity proportion can be quickly adjusted.

The outer plug-in part 11 and the inner plug-in part 12 are of nylon plastic structure.
