Problems solved by technology

Often these systems are so complex that the vehicle must have a hydraulic power source available or an additional power source installed
It is particularly difficult to lift the axle with a mechanical suspension system, the leaf spring must deform as much as possible to lift the axle (bridge), but the leaf spring stiffness is difficult to control, it cannot be offset by reducing some energy, in addition, the lifted The shaft is fixed at a certain position directly above, and needs to be connected to the chassis of the car through chains or anchor cables, and the structure is relatively complicated
In addition, although the suspension method is beneficial to reduce fuel consumption, it will make the load distribution of two or more axes uneven during heavy loads, resulting in cargo transportation safety accidents.

Abstract

A leaf spring suspension system with an air bag lifting axle structure, and a vehicle having same. The leaf spring suspension system with an air bag lifting axle structure comprises: an air bag (4), an equalizing beam (12), a first leaf spring (8), a second leaf spring (15), a first thrust rod (17), a second thrust rod (21), and a front leaf spring support (16), a middle leaf spring support (13), an air bag mounting support (3) and a rear leaf spring support (6) that are respectively and orderly mounted on a frame (5).

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an airbag lifting bridge structure leaf spring suspension system and an automobile. Background technique [0002] At present, the trucks with leaf spring structure, especially those with two or more axles on the rear axle, although the carrying capacity is particularly large, which improves the loading rate, but when these vehicles are empty, they no longer need so many axles to carry, and the two The drag energy consumption generated by the shaft or multiple shafts and the ground increases the fuel consumption rate, and the wheelbase is large, which is not good for handling stability. However, a truck with only one leaf spring structure on the rear axle cannot meet the requirements of large load. In the prior art, the suspension method is usually adopted to meet the requirements of large load, low fuel consumption rate and good handling stability. [0003] Freight vehicles...
