Problems solved by technology

[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. Those who have strict requirements on manufacturing precision and high cost are 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 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

Embodiment Construction

[0022] combine Figure 1-Figure 6 , the present invention provides a horizontal leaf spring type independent suspension structure, including steering knuckle assembly 1 / 7, upper wishbone assembly 3 / 5, steering gear assembly 4, tie rod assembly 2 / 6, front shock absorber Device assembly 8 / 10, horizontal leaf spring assembly 9.

[0023] The horizontal leaf spring assembly is made of spring steel plates into a bow-shaped beam structure, and a single or multiple leaf springs are overlapped and connected together. The two ends of the leaf spring assembly are connected to the steering knuckle assembly through the swing arm ball head The lower end is connected, and the leaf spring and the ball head are riveted or screwed. Preferably, in order to further reduce weight, the leaf spring can also be made of glass fiber reinforced plastic (GFRP) of required specifications. The two ends of the leaf spring are connected to the lower end of the steering knuckle assembly through the swing arm...

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...
