[0028] Embodiment 1:

[0029] like Figure 1-4 As shown in the figure, in order to complete the off-line test of multiple models on one device. When testing multi-axis vehicles, multi-axis synchronization is required. In the past, the equipment installed a motor on each axis. If four-axis linkage is required, it is difficult to control the synchronization of multiple motors. For this reason, a multi-axis synchronous belt drive structure is designed, which allows multiple axes to rotate synchronously.

[0030] Four main rotating shafts 7 are rotatably connected between the two mounting plates 5 , and the four main rotating shafts 7 are at the same horizontal height.

[0031] Auxiliary boxes 10 are arranged on the left and right sides of the side away from each other of the two mounting plates 5. The auxiliary box 10 is connected to two connecting plates 9 by two limiting sliding grooves 16 provided thereon, and the two connecting plates 9 are connected to the rotating column 8 by rotation together. The outer wall of the rotating column 8 is fixedly connected to the second belt gear 4. The two connecting plates 9 are connected to the threaded rod 11 by bearing limiting rotation on the side away from the rotating column 8. The threaded rod 11 is threadedly connected in the thread groove 18 on the auxiliary box 10. The outer wall of the threaded rod 11 is threadedly connected with a nut 17, which is used to stably fix the threaded rod 11 on the auxiliary box 10. The above arrangement can tighten or loosen the toothed belt 2 placed on the second belt gear 4.

[0032] Motors 1 are respectively arranged on the sides of the two mounting plates 5 that are away from each other. The power output shafts of the two motors 1 are connected to the first belt gear 3. The third belt gear 6 is rotatably connected to the two mounting plates 5, and the third belt gear 6 is placed above the first belt gear 3. The two ends of the main rotating shaft 7 are fixedly connected to the fifth belt gear 13.

[0033] A sixth belt gear 14 and a seventh belt gear 15 are respectively arranged on both sides of the bottom of each fifth belt gear 13. The sixth belt gear 14 and the seventh belt gear 15 are both rotatably connected to the mounting plate 5. That is, four sixth belt gears 14 and four seventh belt gears 15 are rotatably connected to both mounting plates 5.

[0034] The first belt gear 3, the third belt gear 6, the two second belt gears 4, the four sixth belt gears 14, the four seventh belt gears 15, and the four fifth belt gears 13 on one of the mounting plates 5 are collectively wrapped with a toothed belt 2. The specific method of wrapping the toothed belt 2 is to first take the first belt gear 3 as the base point, wrap it from the outer wall of the first belt gear 3 on the leftmost second belt gear 4, then wrap it on the first sixth belt gear 14, then wrap it on the fifth belt gear 13, and then wrap it on the outer wall of the seventh belt gear 15. Repeat the wrapping method of the sixth belt gear 14, the fifth belt gear 13, and the seventh belt gear 15 to wrap the four sixth belt gears 14, the fifth belt gear 13, and the seventh belt gear 15, and then continue to wrap the toothed belt 2 at the last seventh belt gear 15 to the outer wall of the second belt gear 4 on the rightmost side, and then wrap it on the third belt gear 6, and then wrap it from the third belt gear 6 back to the first belt gear 3.

[0035] During the winding, the surface area covered by the toothed belt 2 on each belt gear is larger than one fifth of its outer wall, so that the toothed belt 2 is stably wound on each belt gear, that is, each belt gear can rotate stably.

[0036] The two motors 1 on both sides synchronously drive the respective belt gears so that the four main rotating shafts 7 rotate synchronously and stably.

[0037] Embodiment 2: Based on Embodiment 1, a technical means is added to facilitate synchronous testing of multiple axes of a vehicle.

[0038] The two mounting plates 5 are also connected to four auxiliary rotating shafts 12 for common rotation. The four auxiliary rotating shafts 12 are auxiliary mechanisms of the four main rotating shafts 7 and are respectively placed on the sides of each main rotating shaft 7. The horizontal height of the four auxiliary rotating shafts 12 is the same as that of the main rotating shaft 7, and the diameter is the same. One main rotating shaft 7 cooperates with the auxiliary rotating shafts 12 to drive the coaxial wheel hub of one vehicle to rotate.

[0039] The baffle plate 19 is also provided with slots 20 , and each slot 20 is located at the top of a group of the main rotating shaft 7 and the auxiliary rotating shaft 12 .

[0040] The other structures are the same as those in the first embodiment.

[0041] In the specific implementation, in order to make the four main rotating shafts 7 rotate synchronously. The four main rotating shafts 7 have the same diameter and the same horizontal height. The toothed belts of each two adjacent belt gears are connected by winding sleeves, so that the toothed belt covers the sleeve of each belt gear for not less than one-fifth, so that the toothed belt can stably drive each belt gear to rotate. Through the synchronous drive cooperation on both sides of the two motors 1, the four main rotating shafts 7 can rotate synchronously, which is convenient for testing the multi-axle vehicle.

[0042] The provision of a matching auxiliary rotating shaft 12 allows for better testing of multi-axle vehicles.

[0043] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
