Technical Field

[0001] The present disclosure relates to the technical field of student formula racing cars, and in particular to a suspension wishbone of a formula racing car. Background Art

[0002] One of the most important components of a Formula Student car is the suspension, and optimizing the suspension can help optimize the entire car. A suspension that is relatively excellent in performance and meets the requirements of the FSAE competition can not only improve the car's ride smoothness and make the wheels' ground contact better, but also greatly help improve the car's handling stability. At the same time, the interference between the suspension and the steering system can be further reduced by optimizing the layout of the various parts of the car body, so that the vehicle will not easily jump, which is beneficial to improving the lateral angular stiffness of the car body and reducing the vehicle's roll.

[0003] However, since the Formula One car has an open wheel structure, the suspension fork arm is exposed outside the car body, and the wiring is also exposed, which makes it easy to be damaged when the Formula One car is running.

[0021] Embodiment 1

[0022] Please refer to Figure 1 The formula car suspension fork arm comprises a first connecting member 1, one end of which is provided with a first connecting hole 12 for connecting with a wheel system, and the first connecting member 1 is provided with a first connecting portion 6 and a second connecting portion 7 at one end away from the wheel system;

[0023] The first connecting pipe 2 and the second connecting pipe 3 are connected to the first connecting portion 6 and the second connecting portion 7 respectively;

[0024] Specifically, the two ends of the first connecting tube 2 are respectively a first end and a second end, and the first connecting tube 2 is hollow inside and connected to the first end and the second end, wherein the first end is fixedly sleeved on the first connecting portion 6; the two ends of the second connecting tube 3 are respectively a third end and a fourth end, and the second connecting tube 3 is hollow inside and connected to the third end and the fourth end, wherein the third end is fixedly sleeved on the second connecting portion 7.

[0025] The second connecting member 4 and the third connecting member 5 are respectively connected to the second end and the fourth end, and the second connecting member 4 and the third connecting member 5 are respectively provided with a second connecting hole 13 and a third connecting hole 14 for connecting to the frame system;

[0026] A third connecting part 8 is provided at one end of the second connecting member 4 away from the frame system, and the second end is fixedly sleeved on the third connecting part 8 . A fourth connecting part 9 is provided at one end of the third connecting member 5 away from the frame system, and the fourth end is fixedly sleeved on the fourth connecting part 9 .

[0027] A first groove is formed in the first connection part 6, the first groove is connected to the first end, and a first channel is formed in the first connection part 6, the two ends of the first channel are respectively connected to the first groove and the outside of the first connection part 6;

[0028] A second groove is provided in the second connection part 7, the second groove is communicated with the third end, and a second channel is provided in the second connection part 7, the two ends of the second channel are communicated with the second groove and the outside of the second connection part 7 respectively;

[0029] A third groove is provided in the third connection part 8, the third groove is connected to the second end, and a third channel is provided in the third connection part 8, the two ends of the third channel are respectively connected to the third groove and the outside of the third connection part 8;

The first connecting tube 2 and the second connecting tube 3 are hollow inside and connected with both ends. The line can extend from the frame system to the inside of the first connecting tube 2 and the second connecting tube 3, and pass through the first connecting tube 2 and the second connecting tube 3 to be connected to the wheel system, thereby preventing the line from being exposed to the outside, avoiding damage to the line during the driving of the formula car, effectively protecting the line, and improving the degree of structural integration. At the same time, the hollow structure of the first connecting tube 2 and the second connecting tube 3 can reduce the weight.
