Detailed Description

The invention is described in detail below with reference to the accompanying drawings:

referring to fig. 1 to 5, the present invention provides a novel suspension structure of a horizontally-arranged special-shaped plate spring, comprising: the steering device comprises a special-shaped plate spring (1), a special-shaped plate spring (2), a left steering knuckle (3), a right steering knuckle (4), a left steering piece (5), a right steering piece (6), a left damper (7) and a right damper (8); the following details are provided for each component:

the suspension structure mainly comprises two leaf springs with the same shape and size, namely a special-shaped leaf spring (1) and a special-shaped leaf spring (2). As can be seen from fig. 1 to 3, the special-shaped plate spring is different from the long shape of the ordinary plate spring, and two ends of the special-shaped plate spring are bent in the plane, which is similar to a U shape. The special-shaped plate spring (2) is turned 180 degrees relative to the special-shaped plate spring (1), is arranged in a front-back opposite way, and mounting holes at two ends are overlapped. Because the two leaf springs have the same shape and size and can be mutually exchanged, and the left and right suspension swing arms are in a left-right symmetrical structure which is not mutually exchanged, the invention can reduce the number of parts of the whole system and reduce the production and operation cost.

The special-shaped plate spring (1), the special-shaped plate spring (2), the left steering piece (5) and the right steering piece (6) are fixed together through bolts. The through hole (1-1) of the special-shaped plate spring (1) is superposed with the through hole (2-1) of the special-shaped plate spring (2), and the left steering piece (5) penetrates through the through holes (1-1) and (2-1) and then is connected with the left steering knuckle (3). Meanwhile, holes (1-1-1) and (1-1-2) are formed in the two sides of the through hole (1-1), holes (2-1-1) and (2-1-2) are formed in the two sides of the through hole (2-1), and holes (5-1) and (5-2) are formed in the two sides of the left steering piece (5). Two bolts are respectively screwed after passing through the hole (5-1), the hole (1-1-1), the hole (5-1), the hole (1-1-1) and the hole (1-1-1), and the right side of the suspension is the same. To this end, the two profiled leaf springs form a complete frame structure. Because the two ends of the special-shaped plate spring are bent, a stable triangular structure is formed at the wheel edge, so that the wheel has good longitudinal and lateral support performance and high rigidity, and can replace a swing arm. The traditional transverse plate spring is of a lath structure and a cantilever beam structure, has poor rigidity and can only be used as an elastic element to be matched with a swing arm. Meanwhile, the special-shaped plate spring also keeps the elastic characteristic of the plate spring in the vertical direction, so that a spiral spring can be replaced, and the riding comfort is ensured. Therefore, the special-shaped plate spring structure can have the functions of a suspension elastic element and a suspension guide element, the number of parts is reduced, the space is saved, and the light weight is realized.

Although the special-shaped plate spring is connected with the left wheel and the right wheel, the movement of the wheel on one side only can deform the plate spring due to the elastic characteristic of the plate spring, and the movement of the wheel on the other side cannot be influenced. Therefore, the novel transverse special-shaped plate spring suspension structure provided by the invention has the advantages of good comfort and stability of the independent suspension and avoids the defects of complex structure, space occupation and difficult design of the independent suspension.

The left steering knuckle (3) and the right steering knuckle (4) are arranged in a left-right symmetrical mode. The lower end of the left steering knuckle (3) is provided with a mounting point (3-3) which is connected with a left steering piece (5). The left steering knuckle (3) realizes steering capacity through a left steering piece (5). The lower end of the right steering knuckle (4) is provided with a mounting point (4-3) which is connected with a right steering piece (6). The right knuckle (4) achieves steering capability through a right steering member (6).

The left damper (7) and the right damper (8) are arranged in bilateral symmetry. The lower end of the left damper (7) is provided with mounting points (7-1) and (7-2) which are connected with the mounting points (3-1) and (3-2) at the upper end of the left steering knuckle (3). The lower end of the right damper (8) is provided with mounting points (8-1) and (8-2) which are connected with the mounting points (4-1) and (4-2) at the upper end of the right steering knuckle (4). The upper ends of the left damper (7) and the right damper (8) are connected with a vehicle body or an auxiliary frame. During suspension motion, the damper absorbs suspension vibration energy, thereby further improving comfort.

In summary, the novel suspension structure of the transverse special-shaped plate spring provided by the invention has the following advantages:

(1) the special-shaped plate spring structure can have the functions of a suspension elastic element and a suspension guide element, the number of parts is reduced, the space is saved, and the light weight is realized.

(2) The special-shaped plate spring structure is simultaneously connected with the left wheel and the right wheel, but the left wheel and the right wheel are not influenced mutually due to the elasticity of the special-shaped plate spring structure, so that the suspension has the characteristics of an independent suspension, and the comfort and the operation stability are good.

(3) The two profile leaf springs can form a stable triangular structure at the wheel rim, and can provide more excellent supporting rigidity.

(4) The special-shaped plate spring (1) and the special-shaped plate spring (2) are the same in shape, so that the production efficiency can be improved, and the production cost can be reduced.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and improvements can be made without departing from the principle of the present invention, and such modifications and improvements should also be considered within the scope of the present invention.
