Detailed Description of the Preferred Embodiment

[0021] Please refer to Figures 1-4 , a transmission structure of a formula racing car, including a mounting plate 1. On both sides of the upper surface of the mounting plate 1, first support plates 2 are fixedly installed. Fixed tubes 3 are inserted and slidably installed on the first support plates 2. Transmission shafts 6 are rotatably installed inside the fixed tubes 3 through bearings. Universal joints 7 are fixedly installed at the opposite ends of the two transmission shafts 6 for installing wheels. Push tubes 5 are fixedly installed on the outer surfaces of both ends of the fixed tubes 3. Two hydraulic rods 8 are fixedly installed on the first support plates 2. One ends of the hydraulic rods 8 are fixedly connected to the surfaces of the inner push tubes 5.

[0022] By starting the hydraulic rods 8, the push tubes 5 are driven to move. The push tubes 5 drive the fixed tubes 3 to move, driving the transmission shafts 6 to move horizontally, facilitating the adjustment of the wheelbase between the two wheels according to requirements;

[0023] On the upper surface of the mounting plate 1, two second support plates 11 are fixedly installed. The two second support plates 11 are arranged between the two first support plates 2. Rotating sleeves 12 are rotatably installed on the second support plates 11 through bearings. On the outer surfaces of the opposite ends of the two rotating sleeves 12, driven sprockets 13 are fixedly installed. On the upper surface of the mounting plate 1, two engines 14 are installed. On the outer surface of the output shaft of the engine 14, a driving sprocket 15 is fixedly installed. A transmission chain 16 is drivingly connected between the driving sprocket 15 and the driven sprocket 13. On the outer surfaces of the opposite ends of the two transmission shafts 6, a plurality of second limiting edges 9 are fixedly installed. The transmission shafts 6 together with the second limiting edges 9 are inserted and slidably arranged inside the rotating sleeves 12.

[0024] By starting the corresponding engine 14, the driving sprocket 15 is driven to rotate. The driving sprocket 15 drives the driven sprocket 13 to rotate through the transmission chain 16, driving the rotating sleeve 12 to rotate. The transmission sleeve 12 drives the transmission shaft 6 to rotate through the second limiting edge 9, which is convenient for driving the corresponding wheels to rotate and facilitating the driving of the formula racing car. The transmission shafts 6 together with the second limiting edges 9 are inserted and slidably arranged inside the rotating sleeves 12, which can ensure that the transmission shafts 6 slide normally left and right in the rotating sleeves 12, and the rotating sleeves 12 can drive the transmission shafts 6 to rotate normally. After adjusting the wheelbase between the two wheels, it will not affect the normal driving and working of the engine 14 driving the transmission shafts 6.

[0025] Among them, a plurality of first limiting edges 4 are uniformly installed on the outer surface of the fixed pipe 3. A limiting chute is opened inside the first support plate 2. The first limiting edges 4 are slidably arranged inside the limiting chute, which is used to limit the fixed pipe 3 and prevent the fixed pipe 3 from rotating on the first support plate 2 and affecting the stability of the transmission shaft 6.

[0026] Furthermore, a motor mounting plate is welded on the upper surface of the mounting plate 1. A plurality of bolts are arranged on the motor mounting plate. The engine 14 is fixedly installed on the motor mounting plate through bolts, which is convenient for the disassembly and installation of the engine 14. At the same time, it can reduce the contact area between the engine 14 and the mounting plate 1 and facilitate the heat dissipation of the engine 14.

[0027] Among them, a plurality of bolt holes are opened at the edge of the upper surface of the mounting plate 1, which is convenient for the mounting plate 1 to be installed inside the racing car. A plurality of weight-reducing grooves are opened on the upper surface of the mounting plate 1, which are used to reduce the self-weight of the racing car.

[0028] Refer to Figure 4, a support plate three 17 is also fixedly installed on the upper surface of the mounting plate 1. A connecting cylinder 18 is rotatably installed on the support plate three 17. A connecting cavity 19 is arranged inside the connecting cylinder 18. The opposite ends of the two transmission shafts 6 both extend into the connecting cavity 19. Connecting blocks 10 are fixedly installed at the opposite ends of the transmission shafts 6. A group of electric push rods 20 are fixedly installed on both the upper and lower inner walls of the connecting cavity 19. One end of each group of electric push rods 20 is fixedly connected to a pressing plate 21. The pressing plate 21 matches the shape of the connecting block 10. When one engine 14 is damaged, the electric push rods 20 inside the connecting cylinder 18 can be started to drive the pressing plate 21 to move towards the center of the connecting cavity 19 to fix the two connecting blocks 10, facilitating the connection of the two transmission shafts 6 into a whole, enabling one engine 14 to drive the two transmission shafts 6 to rotate and drive the two wheels to rotate simultaneously, ensuring that the formula racing car can still drive normally and facilitating the driver to drive the racing car to the repair location for repair.

[0029] Further, the outer surface of the connecting block 10 and the inner surface of the pressing plate 21 are both rough friction surfaces, which are used to increase the friction force between the pressing plate 21 and the connecting block 10, preventing the connecting block 10 from sliding relative to the pressing plate 21 when the pressing plate 21 fixes the connecting block 10 and affecting the normal driving of the racing car.

[0030] Working principle: For the transmission structure of this formula racing car, during operation, by starting the corresponding engine 14, the driving sprocket 15 can be driven to rotate. The driving sprocket 15 drives the driven sprocket 13 to rotate through the drive chain 16, driving the rotating sleeve 12 to rotate. The transmission sleeve 12 drives the transmission shaft 6 to rotate through the sleeve limiting edge two 9, facilitating the driving of the corresponding wheels to rotate and facilitating the driving of the formula racing car. By starting the hydraulic rod 8, the push tube 5 can be driven to move. The push tube 5 drives the fixed tube 3 to move, driving the transmission shaft 6 to move horizontally, facilitating the adjustment of the wheelbase between the two wheels according to requirements without affecting the normal driving of the engine 14 to drive the transmission shaft 6. When one engine 14 is damaged, the electric push rods 20 inside the connecting cylinder 18 can be started to drive the pressing plate 21 to move towards the center of the connecting cavity 19 to fix the two connecting blocks 10, facilitating the connection of the two transmission shafts 6 into a whole, enabling one engine 14 to drive the two transmission shafts 6 to rotate and drive the two wheels to rotate simultaneously, ensuring that the formula racing car can still drive normally and facilitating the driver to drive the racing car to the repair location for repair.
