Air suspension system applied to heavy truck

Abstract

The invention discloses an air suspension system applied to a heavy truck. The air suspension system comprises a balance beam, an axle, a frame and air spring assemblies, wherein the entire balance beam has a C-shaped structure of which the opening is upward; the middle part of the balance beam is connected with the axle; and the upper sides of the two end parts of the balance beam are provided with one air spring assembly respectively. The air suspension system can be used for solving the technical problems of non-smooth running of the truck, reduction in the riding comfort and easy damage to truck-mounted goods in the running process caused by lagging phenomenon of a steel plate spring, no contribution to the overall arrangement and the running stability of the entire truck, larger dead-weight, increase in oil consumption, no contribution to energy saving and emission reduction, and the like. Meanwhile, the invention further provides a highly reliable air suspension applied to the heavy truck, so that the dead-weight of the entire truck is lowered, the comfort and the smoothness of the truck in the running state are improved at the same time, the working state is reliable, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of manufacturing a chassis system applied to heavy trucks, and in particular relates to an air suspension system applied to heavy trucks. Background technique [0002] At present, in the field of heavy-duty truck upper chassis system manufacturing technology, most of the rear suspensions of trucks use leaf springs as elastic elements, thereby playing the role of mitigating impact and damping vibration. With the continuous development of vehicle technology, the driver of the vehicle and the valuables on the vehicle have put forward higher requirements for the comfort of the truck. The rear suspension of the truck in the prior art adopts the structural form of the leaf spring, which is increasingly unable to meet the requirements. Market demand, and there are still many technical problems: [0003] 1. When the rear suspension of trucks in the prior art uses leaf springs, since the stiffness of the leaf spring...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is that the rear suspension of the truck in the prior art adopts a leaf spring structure, and the hysteresis of the leaf spring causes the roughness of the automobile running, reduces the comfort of the ride, and makes it easy for the vehicle to carry goods while driving. damage during the process; it is not conducive to the layout of the vehicle and the stability of the vehicle, resulting in a large weight of the vehicle, increased fuel consumption, and is not conducive to technical problems such as energy saving and emission reduction. An air suspension applied to heavy trucks is provided. system
