Transverse plate spring type independent suspension structure

Abstract

The invention provides a t transverse plate spring type independent suspension structure. The transverse plate spring type independent suspension structure comprises a knuckle pivot assembly, an upper fork arm assembly, a steering gear assembly, a tie rod assembly, a front vibration damper assembly and a transverse plate spring assembly. Since a transverse plate spring scheme is employed, a transverse plate spring replaces left and right lower swing arms and also has the effect of a transverse stabilization rod, an inclined pull bar structure is omitted, a guide effect is exhibited, one component has multiple functions, the structure is simpler, the weight of a front suspension structure is greatly reduced, the rigidity of the plate spring assembly is enhanced through a corresponding clamping structure, a reed is not offset back and forth when the structure handles impact from the front side of an automobile, the structure especially reduces the dimension of the front suspension structure in a height direction, and the structure is suitable for a miniaturized motor vehicle and a miniaturized electric vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile design and manufacture, in particular to a transverse leaf spring type independent suspension structure. Background technique [0002] At present, there are many front axles of vehicles at home and abroad, and widely used include McPherson independent options and double-wishbone independent suspensions. The latter has strict requirements on manufacturing precision and high cost, making it difficult to be widely used. [0003] The two ends of the existing leaf springs are usually connected by rolling ears. There is a gap in this connection, and there is noise during driving; the layout is mostly longitudinal, symmetrical on both sides, and the structure is complicated, so it is difficult to really reduce weight; the material is mostly springs. Steel plates have high density, low energy storage per unit mass, and low fatigue strength. Once broken, serious consequences will occur. Most of the ex...

[0003] The two ends of the existing leaf springs are usually connected by rolling ears. There is a gap in this connection, and there is noise during driving; the layout is mostly longitudinal, symmetrical on both sides, and the structure is complicated, so it is difficult to really reduce weight; the material is mostly springs. Steel plate has high density, low energy storage per unit mass, and low fatigue strength. Once it breaks, it will have serious consequences

Most of the existing independent suspensions of small electric vehicles are MacPherson structures, which often include stabilizer bars, diagonal stays, and swing arms. type design, while the structure of the double wishbone suspension is complex, the precision of the components is extremely high, and the cost is high, so it is difficult to be widely used in small electric vehicles
