Problems solved by technology

[0004] The suspension system is one of the important components of the chassis of a formula car. The design of the suspension directly affects the handling stability of the car. If the suspension design is too hard, the car responds quickly but the lateral stability is poor; if the design is too soft, it will make the car corner. There is serious body roll, there will be obvious body pitch when accelerating and braking, and the response is lagging. In addition, the suspension system must transmit the force and moment between the frame and the wheels to ease the impact load transmitted to the frame by the road surface. damping vibration

Embodiment 1

[0021] see Figure 1-4 , in the embodiment of the present invention, a kind of small racing car three-spring damping suspension structure, comprises rear suspension and front suspension, and described rear suspension comprises right rear suspension, left rear suspension and rear stabilizer bar 5, and front Suspension comprises right front suspension, left front suspension and front stabilizer bar 19, and described right rear suspension and left rear suspension have respectively symmetrically arranged on rear stabilizer bar 5 both sides, and described right rear suspension and left rear suspension Both have a rear column 1, the upper and lower ends of the rear column 1 have rear column lugs 10, and the rear upper control arm 2 and the rear lower control arm 4 are respectively arranged on the inner side of the upper and lower ends of the rear column 1. There is a lower wishbone plate 3, on which a push rod 11 that is rotatably connected to the lower wishbone plate 3 is provided,...

Embodiment 2

[0025] On the basis of Embodiment 1, the number of the rear upper control arm 2 and the rear lower control arm 4 is two and distributed in a "V" shape. The front upper control arm 15 and the front lower control arm 16 There are two and they are distributed in a "V" shape. There are yoke lugs at the front end of the rear upper control arm 2, the front end of the rear lower control arm 4, the front end of the front upper control arm 15 and the front end of the front lower control arm 16. 17.

Abstract

The invention discloses a three-spring damping suspension structure of a small racing car. The three-spring damping suspension structure comprises a rear suspension and a front suspension, wherein therear suspension comprises a right rear suspension body, a left rear suspension body and a rear stabilizer bar, the front suspension comprises a right front suspension body, a left front suspension body and a front stabilizer bar, and the right rear suspension body and the left rear suspension body are symmetrically arranged on the two sides of the rear stabilizer bar correspondingly. According tothe structure, proper wheel positioning parameters can be ensured; ideal front and rear suspension rigidity and reasonable rigidity distribution of the suspensions are ensured; the rigidity of an anti-roll bar is reasonably matched with the rigidity of the suspensions; and the adjustability of the suspension system is ensured, and parts are easy to disassemble and assemble and convenient to maintain.

Description

technical field [0001] The invention relates to a racing car suspension technology, in particular to a three-spring shock-absorbing suspension structure for a small racing car. Background technique [0002] The difference in the structure and performance of the suspension of the racing car will directly affect the handling performance of the car. For FSCC racing cars, the success of the suspension design directly affects the overall performance level of the car. The design of the suspension includes the selection of the suspension type, the design and selection of each component, and the dynamic and static optimization of the suspension system. Analysis, so that the car meets the competition requirements, and the parameters of the car are as optimal as possible. [0003] As one of the important components of the racing car chassis, the structural characteristics of the suspension system are crucial to the handling stability and smoothness. The unequal-length double-wishbone...
