[0024] like Figure 1 and Figure 3As shown, a support plate 7 is fixedly connected between the two groups of fixed rods 101 mentioned above, and the bottom of the support plate 7 is in contact with the bottom of the upper belt surface of the transmission belt 6, so as to support the tire on the transmission belt 6 and improve the stability of the tire rotation. At the same time, an electric heating rod 701 is fixedly connected to the inner wall of the support plate 7, and the support plate 7 is heated by starting the electric heating rod 701, and the heat is transferred to the transmission belt 6 through the support plate 7, thereby simulating the road surface in hot weather and improving the authenticity of the simulation data.

[0025] like Figure 1 As shown, a water tank 8 is fixedly connected to the bottom of the fixing frame 1, a water supply pump 801 is fixedly connected to the top of the water tank 8, a water inlet end of the water supply pump 801 is connected to the water tank 8, and water is drawn from the inside of the water tank 8, a nozzle 802 is fixedly connected to one side of a group of fixing rods 101, an output end of the water supply pump 801 is connected to the nozzle 802, and the water drawn by the water supply pump 801 is sprayed from the nozzle 802 to the transmission belt 6, thereby simulating a slippery road surface and improving the authenticity of the simulation data, and at the same time, a collecting box 9 is fixedly connected to the bottom of the fixing frame 1, and the collecting box 9 is connected to the water tank 8, so that water is collected and recycled.

[0026] like Figure 1 and Figure 4 As shown, a fixing plate 403 is fixedly connected to one side of the connecting frame 4, a driving motor 402 is fixedly connected to the fixing plate 403, an output end of the driving motor 402 is fixedly connected to a driving shaft 421 through a transmission shaft 404, an auxiliary motor 405 is fixedly connected to the top of the fixing plate 403, an output end of the auxiliary motor 405 is transmission-connected to the transmission shaft 404 through a gear set 406, the driving motor 402 drives the tire to rotate through the transmission shaft 404 and the driving shaft 421, after a period of testing, the driving motor 402 can be stopped, and then the auxiliary motor 405 can be started.

At this time, the tire cannot move downward, and the spring 302 on the outer wall of the sliding rod 301 is squeezed and contracts, thereby applying pressure to the tire through the tension of the contracted spring 302. When the pressure applied by the spring 302 reaches the approximate pressure that the tire is subjected to when installed on the vehicle, the adjusting rod 2 is stopped, so that the tire simulates the stress state when installed on the vehicle, and then the driving motor 402 is started. The driving motor 402 drives the tire to rotate on the transmission belt 6 through the driving shaft 421 for testing, thereby improving the accuracy of the test simulation effect.

All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
