Front overhang swing arm stabilizer rod device for cab of heavy duty vehicles

Abstract

The invention discloses a front suspension arm stabilizer bar device of a heavy-duty truck cab. In order to further improve the reliability of the cab front suspension arm stabilizer bar device, the front suspension arm stabilizer bar and the bearing structure are redesigned, providing A front suspension arm stabilizer bar device: at the front side of the stabilizer bar swing arm, the T-shaped bearing adopts an interference fit to the front suspension support hole, and this structure is easy to disassemble; the T-shaped bearing uses MC nylon with a thickness of 5mm, and the material Withstand high-strength loads, with high wear resistance, self-lubrication, and no abnormal noise; at the rear of the stabilizer bar swing arm, the joint between the swing arm and the bearing adopts a tapered structure interference fit, which is easy to assemble and disassemble. The material of the bearing is Using polyurethane, its wear resistance and heat resistance are better than rubber. The beneficial effects of this solution can be known from the description of the above solution, the structure is simple, the design is reasonable, the service life of the front suspension system is improved, and the stability, reliability and safety of the vehicle are improved.

Description

technical field [0001] The invention relates to an air intake system of a heavy-duty truck, in particular to a front suspension arm stabilizer bar device of a cab of a heavy-duty truck. Background technique [0002] The front side bearing of the swing arm stabilizer bar of the traditional front suspension system has two structural forms, one is a rigid bearing, and its disadvantage is that it is prone to abnormal noise during driving; the other is a rubber bearing structure, which adopts rubber and metal vulcanization bonding The structure adopts a cylindrical structure, which is interference fit with the round hole of the front suspension arm. The disadvantage is that the rubber is easy to age, has poor heat resistance and wear resistance, and because the cylindrical bearing and the front suspension arm adopt an interference fit, it is inconvenient to disassemble after the bearing is damaged. The rear side bearing of the swing arm stabilizer bar of the traditional front su...
