The second adaptive component 12 includes a second rotating arm 9 The second shock-absorbing member 10, the second rotating arm 9 is provided with two, and is arranged in an upper and lower manner, one end of the second rotating arm 9 is connected to the rear wheel 13, and the other end is rotatably connected to the rear frame 11, and the two ends of the second shock-absorbing member 10 are respectively connected to the rear frame 11 and the second rotating arm 9 located below. The first shock-absorbing member 5 and the second shock-absorbing member 10 have the same structure. The first shock-absorbing member 5 includes a first rotating seat 26, a spring 25 and a second rotating seat 23. The first rotating seat 26 is rotatably mounted on the first rotating arm 4 or the second rotating arm 9, and the second rotating seat 23 is rotatably mounted. Installed on the front frame 3 or the rear frame 11, the two ends of the spring 25 are respectively in conflict with the first rotating seat 26 and the second rotating seat 23, the first rotating arm 4 and the front wheel 1, the second rotating arm 9 and the rear wheel 13, the drive shaft 17 and the front wheel 1 and the rear wheel 13 are connected at the joints using a universal ball joint structure. When the front wheel 1 and the rear wheel 13 pass through a roadblock or an uneven road section, the first shock absorbing member 5 and the second shock absorbing member 10 reduce the height change of the wheel during the ups and downs, so that the car can remain stable while driving, and the front wheel A hydraulic support member 6 is also added to the side of 1, which can exert a reaction during the ups and downs of the front wheel 1, thereby reducing the vibration transmitted to the cab, so as to maintain driving comfort and make the front of the vehicle more stable when driving. An adjustment ring 24 is provided on the second rotating seat 23, and the adjustment ring 24 is threadedly connected to the second rotating seat 23, and the outer side of the adjustment ring 24 is provided with anti-slip convex grooves.

By adopting a structure in which the front wheel 1 and the rear wheel 13 are driven simultaneously, greater power can be obtained, thereby shortening the starting time and providing greater acceleration.

[0022] An exhaust pipe 8 is provided on the side of the base plate 30. The air intake end of the exhaust pipe 8 is connected to the exhaust port of the engine 18, and the exhaust port of the exhaust pipe 8 is arranged toward the rear wheel 13. The exhaust pipe 8 is arranged close to the side of the base plate 30, which can reduce the space occupied, thereby reducing the size of the overall layout. In this way, the center of gravity of the frame can be close to the center position of the base plate 30, which can further improve stability.

[0023] In this example, when the racing car is running, its power comes from the engine 18, which drives the gear box 19 to rotate, and then drives the power system 15 to work, and makes the front wheels 1 and the rear wheels 13 rotate to allow the racing car to start and run normally. The front wheels 1 and the rear wheels 13 are driven at the same time, which can provide greater horsepower, thereby shortening the starting time, and the front frame 3, the rear frame 11 and the power system 15 are all installed on the bottom plate 30. By reasonably designing the layout between the three, the overall frame structure can be made more compact, and the drive shaft 17 connected to the power system 15 is located between the first adaptive component 2 and the second adaptive component 12, which can save installation space. The above design can lower the center of gravity of the entire frame, making the racing car more stable when driving. At the same time, the overall volume of the frame is reduced, which can reduce wind resistance, so that the racing car has more advantages in starting and accelerating.
