To ensure safe driving, the anti-skid property of the tire is an important indicator. Car tires are one of the important parts of a car. Most car tires are made of rubber and are usually used for 5 to 6 years. After long-term use, the tires will age and wear, and it is very easy to have a blowout and pattern wear.

[0015] A method for testing the skid resistance of all-season tires for new energy vehicles, comprising the following steps: S1. Move the tire to be tested to a position close to the loading and unloading mechanism, dump it on the inner side of the clamping frame, and then drive the bidirectional screw rod to rotate through the second motor so that the clamping frames can be merged in opposite directions. During the merging process, the support frame clamps the tire in place.

[0016] S2. Then, the first motor drives the lifting screw to rotate, driving the transverse slide rail and the tire to rise. While rising, the steering gear rotates, driving the tire to rotate to the top of the rotating mechanism. Then, the first motor drives the lifting screw to rotate in the reverse direction, controlling the clamping frame and the tire to descend, thereby facilitating the placement of the tire on the rotating mechanism, and then the clamping frame is unfolded and reset.

[0017] S3. After being placed on the rotating mechanism, the pneumatic controller pneumatically controls the extension of the pneumatic telescopic rod, so that the inner support plate is squeezed on the tire, thereby facilitating the limiting fixation of the tire. Subsequently, the rotating motor drives the support ring to rotate, and synchronously drives the tire to rotate. During the rotation, the support rod cooperates with the support wheel to provide stable lateral support to ensure stability.

[0018] S4. Use the electric telescopic rod to push the mounting base and the anti-skid test pad close to the surface of the tire. By adjusting the squeezing force of the close fit, it is convenient to effectively test the tire. At the same time, the anti-skid test pad can be installed and disassembled through the sliding rail, which is conducive to changing the anti-skid test pad according to different test road requirements.

[0019] S5. During the test, the test liquid is pumped out through a delivery pump and a delivery pipe, and then delivered to the sprinkler head through a water pipe, effectively spraying the test liquid on the surface of the tire, thereby facilitating simulated testing of rainy roads and expanding the scope of the test.

[0020] S6. During the spray test, the dripping water will be filtered through the coarse filter plate and the fine filter plate respectively. After filtering, the water will be collected and processed in the collection box for easy recycling and energy saving. The drain pipe is convenient for discharging water when it is not needed.

[0021] S7. After the test is completed, the clamping frame is moved to the outside of the tire for clamping, and then it is driven to move to a position close to the ground and placed to complete the test.

[0022] Compared with the prior art, the present invention has the following beneficial effects: 1. Move the tire to be tested to a position close to the loading and unloading mechanism, dump it on the inner side of the clamping frame, and then drive the bidirectional screw to rotate through the second motor, so that the clamping frame can be merged in opposite directions. During the merging process, the support frame clamps the tire and positions it. Then, the lifting screw is driven by the first motor to rotate, driving the lateral slide rail and the tire to rise. While rising, the steering machine rotates, driving the tire to rotate above the rotating mechanism. Then, the lifting screw is driven by the first motor in the reverse direction to rotate, and the clamping frame and the tire are controlled to descend, so that the tire can be placed on the rotating mechanism. Then, the clamping frame is unfolded and reset. Rapid loading and unloading reduces the degree of dependence on manual operation. Traditional loading and unloading methods may require multiple workers to spend a long time to complete, while efficient loading and unloading mechanisms can complete the same task in a shorter time, thereby reducing the required manpower input. This not only reduces direct labor costs, but also reduces errors and unstable factors that may be caused by manual operation. Rapid loading and unloading ensures the continuity of tire testing. When a tire is tested, it can be quickly removed and replaced with a new tire to be tested, which also helps to establish a more stable testing environment and process. 2. The test liquid is pumped out through a delivery pump and a delivery pipe, and then delivered to the spray head through a water pipe for spraying, effectively spraying the test liquid on the surface of the tire, thereby facilitating simulated testing of rainy roads and increasing the scope of the test. During the spray test, the dripping water source will be filtered through the coarse filter plate and the fine filter plate respectively. After filtration, the water source will be collected and processed in a collection box for easy recycling and energy saving. The drain pipe is convenient for discharging the water source when it is not needed.

[0023] 3. By using the electric telescopic rod to push the mounting base and the anti-skid test pad close to the surface of the tire and adjusting the squeezing force for close fitting, it is convenient to effectively test the tire. At the same time, the anti-skid test pad can be installed and disassembled through the sliding rail, which is conducive to changing the anti-skid test pad according to different test road requirements and improving the test range.

A steering machine is arranged at the bottom of the lifting frame 201, and the tire to be tested is moved to a position close to the loading and unloading mechanism 2, and it is dumped and placed on the inner side of the clamping frame 209, and then through The second motor 208 drives the bidirectional screw rod 207 to rotate, so that the clamping frame 209 can be merged in opposite directions. During the merging process, the support frame 210 clamps the tire in place, and then the first motor 204 drives the lifting screw rod 205 to rotate, driving the transverse slide rail 206 and the tire to rise. While rising, the steering machine rotates to drive the tire to rotate above the rotating mechanism 3, and then the first motor 204 drives the lifting screw rod 205 to rotate in the reverse direction to control the clamping frame 209 and the tire to descend, thereby facilitating the placement of the tire on the rotating mechanism 3. Then, the clamping frame 209 Unfold and reset, and reduce the reliance on manual operation through fast loading and unloading. Traditional loading and unloading methods may require multiple workers to spend a long time to complete, while efficient loading and unloading mechanisms can complete the same task in a shorter time, thereby reducing the required manpower input. This not only reduces direct labor costs, but also reduces the errors and unstable factors that may be caused by manual operation. Fast loading and unloading ensures the continuity of tire testing. When a tire is tested, it can be quickly removed and replaced with a new tire to be tested. It also helps to establish a more stable test environment and process.

When the vehicle is driving, the tire is subjected to various forces from the road surface, and the rotating mechanism 3 can simulate, to a certain extent, the internal support force that the tire is subjected to when it is installed on the wheel. By conducting anti-skid tests in this way, it is possible to better predict the anti-skid performance of the tire in actual use.

[0030] like Figure 4 As shown, the rotating mechanism 3 also includes a bracket 301, and a plurality of support rods 302 are evenly distributed along the circumferential direction on the top of the bracket 301. A support wheel 303 is arranged on the top of the support rod 302. The support wheel 303 is movably connected to the bottom of the support ring 304.

During the test, the test liquid is extracted through the delivery pump 405 and the delivery pipe 404, and then delivered to the spray head 407 through the water delivery pipe 406 for spraying, so that the test liquid is effectively sprayed On the surface of the tire 310, it is convenient to simulate the test of the rainy road surface and improve the scope of the test. During the spray test, the dripping water source will be filtered through the coarse filter plate 402 and the fine filter plate 403 respectively. The filtered water source will be collected and processed through the collection box 401, which is convenient for recycling and energy saving.
