Welding type guide arm commercial vehicle air suspension and welding method thereof

Abstract

The invention discloses a Welding type guide arm commercial vehicle air suspension and a welding method thereof. A guide arm support and an air bag are arranged under a frame girder, the bottom of theair bag is connected with a guide arm through a bolt, the side face of the guide arm is connected with a guide arm support through a pin shaft, a shock absorber support is arranged in the middle of the guide arm, the pin shaft penetrates through the shock absorber support, a shock absorber protection belt fixing support and a flat washer and is connected with the lower end of the shock absorber through a nut, the upper end of the shock absorber is connected with the guide arm support through the pin shaft and the nut, an air supply pipeline connector is fixed to the top of the air bag throughthe nut, the air supply pipeline connector is connected with a height control valve through the air pipe, a lining plate is welded to one end of an axle, and the axle welded with the lining plate connects a left frame and a right frame into a closed-loop structure by connecting a left guide arm and a right guide arm. The number of parts is reduced, the structure is simpler and more compact, axlebolts are free of maintenance, and later vehicle maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of air suspension manufacturing of auto parts, in particular to a welded guide arm commercial vehicle air suspension and a welding method thereof. Background technique [0002] With the continuous maturity of air suspension technology and the promotion of national policies, the application of air suspension technology in automobiles is becoming more and more popular. The air suspension can not only effectively buffer the impact of the uneven road surface on the vehicle, improve the driver's ride comfort, but also reduce the damage rate of the cargo on the vehicle and reduce the fuel consumption per kilometer of the vehicle. However, unlike the simple, reliable and durable structure of the leaf spring suspension, the maintenance cost of the air suspension remains high in the later stage. Core parts such as airbags, shock absorbers, and height valves need regular maintenance. The parts need to be maintained m...

AI Technical Summary

Problems solved by technology

However, unlike the simple, reliable and durable structure of the leaf spring suspension, the maintenance cost of the air suspension remains high in the later stage. Core parts such as airbags, shock absorbers, and height valves need regular maintenance. The parts need to be maintained more frequently, especially when the vehicle is driving on a road with a slight overload, gravel road and other poor road conditions for a long time, the frequency of axle bolt loosening is 200% higher than that on high-speed roads

If it is not maintained in time, the chassis parts will be damaged, and even the vehicle will have an accident.
