Automobile front suspension structure

Abstract

The invention provides an automobile front suspension structure, belonging to the technical field of automobile front suspensions. The automobile front suspension structure comprises two steering knuckle assemblies, wherein each steering knuckle assembly is connected with an automobile body through a shock absorber assembly, the two steering knuckle assemblies are connected with the two ends of a fixing frame through swing arms respectively, the two ends of the fixing frame are connected with the automobile body, the fixing frame is connected with an inverted transversely-arranged plate spring capable of adjusting a movement stroke, and the two ends of the inverted transversely-arranged plate spring are slidably connected with the two swing arms respectively. The automobile front suspension structure has the advantages that the structure is simple and compact, development cost is low, vibration absorption and noise reduction are achieved, buffering and damping effects are improved, driving comfort is improved, and the structure is suitable for different vehicle types and driving road surfaces.

Description

technical field [0001] The invention relates to the technical field of automobile front suspension, in particular to an automobile front suspension structure. Background technique [0002] At present, traditional automobile suspension mainly includes torsion bar suspension, McPherson independent suspension and multi-link independent suspension. Due to the economy, practicality and low cost of the MacPherson independent suspension, it is a more commonly used suspension structure in current models, while the cost of the multi-link independent suspension is much higher than that of the MacPherson independent suspension due to structural and manufacturing technology problems. independent suspension. [0003] The existing McPherson independent suspension includes two sets of shock absorber assemblies, a steering knuckle assembly, a swing arm, a subframe and a stabilizer bar, and one end of the steering knuckle assembly is connected to the shock absorber assembly Tightly connect...

AI Technical Summary

Problems solved by technology

The existing MacPherson independent suspension has the following disadvantages: 1. Since the existing MacPherson independent suspension mainly relies on the shock absorber assembly to achieve the shock absorption effect, and the degree of shock absorption is certain and cannot be adjusted, in many 2. Since the swing arm is tightly connected with the sub-frame to form a steel connector, when the vehicle turns or brakes, the cushioning effect is poor, causing the steering roll and braking The phenomenon of nodding is more obvious; and when the car passes through rough roads, the swing arm and the sub-frame shake while the body shakes, and the friction with the surrounding components produces a large noise, and even the distortion of the relevant components occurs, which reduces the suspension. The service life of the structure; 3. For low-speed electric vehicles driven by one person, due to the narrow body width, this kind of suspension structure has a large span and takes up a lot of space, which cannot meet the installation and man-machine requirements. The structure is modified, which increases the processing cost
