Front air suspension with low chassis and automobile

Abstract

The invention belongs to the technical field of automobile chassis, and relates to a front air suspension with a low chassis and an automobile. The front air suspension comprises an air spring, a longitudinal rod integrated stabilizer bar, a lateral propelling rod, and an oscillating damper; the air spring is arranged at the lower side of a vehicle frame, and arranged on a front shaft through an air spring lower integrated support; the two ends of the longitudinal rod integrated stabilizer bar are connected with the air spring lower integrated support, and the middle of the longitudinal rod integrated stabilizer bar is assembled with a connecting bracket; the lower end of the oscillating damper is connected with the air spring lower integrated support, and the upper end of the oscillatingdamper is connected with the vehicle frame; and the left end of the lateral propelling rod is connected with the air spring lower integrated support, and the right end the lateral propelling rod is connected with a vehicle frame connecting bracket. The automobile comprises the front air suspension with the low chassis. The front air suspension with the low chassis involved in the invention solvesa problem that a conventional four-rod structure is difficult to be arranged in a low-chassis vehicle model, reduces weight, lowers cost, effectively improves the local anti-roll capacity of the vehicle frame, can realize driving in the state that a height of the vehicle frame above ground is 800 mm, simultaneously reduces air resistance and center of gravity, and synchronously improves oil consumption and dynamic properties.

Description

technical field [0001] The invention belongs to the technical field of automobile chassis, and relates to a low-chassis front air suspension and an automobile matching the low-chassis front air suspension. Background technique [0002] As laws and regulations become stricter and penalties for violations such as exceeding the limit and speeding increase, the legal Dora Express has become the most important problem at present, especially in the subdivided fields such as express delivery, which are light and bulky. The cargo box of the low-chassis model is lower than the ground, and it is easier and less labor-saving when loading and unloading goods. The lower floor means that the center of gravity of the vehicle is lower, and the driving stability of the vehicle will be better. The most important thing is to be able to load more goods in larger volume cargo boxes. Of course, the lower chassis affects the passability of the vehicle, and many places with deviated road condition...

AI Technical Summary

Problems solved by technology

This kind of air suspension application is very mature, and the cost is relatively expensive

When market segments require low chassis with a frame height of 800-900mm from the ground, due to the limitation of the distance from the wheel center to the frame, it is difficult to arrange the four longitudinal thrust rods, which leads to the loss of business opportunities for OEMs
