Problems solved by technology
[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, and has poor heat resistance and wear resistance. 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 suspension system adopts a rubber bearing structure, which has the same disadvantages as the front rubber bearing of the swing arm

Abstract
The invention discloses a front overhang swing arm stabilizer rod device for the cab of heavy duty vehicles. The front overhang swing arm stabilizer rod and a bearing structure are designed once againto further improve the stability of the front overhang swing arm stabilizer rod device for the cab, and the front overhang swing arm stabilizer rod device is provided. In the device, a T-shaped bearing is in interference fit to an overhang support hole in front of the swing arm of a stabilizer rod, and the structure is convenient to detach; the T-shaped bearing is made from MC nylon having a thickness of 5mm, which can ensure high strength load and the characteristics of high abrasion resistance, self lubrication and no abnormal sound; conical structure interference fit is adopted at the joint of the swing arm and the bearing, behind the swing arm of the stabilizer, and the structure is convenient to assemble and disassemble; and the bearing is made from polyurethane, and has abrasion resistance and heat resistance superior to those of rubber. According to the technical scheme, the device has the beneficial effects of simple structure and reasonable design, the service life of an overhang system is prolonged, and the stability, reliability and safety of vehicles 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...
