[0002] Tires are one of the important components of vehicles. The ring-shaped tires are the only parts of the vehicle that come into contact with the ground. Tires are often used in complex and harsh environments. When the vehicle is driving, the tires are subjected to various deformations, loads, forces, and high and low temperature effects. Wear during the use of tires is inevitable. The research and design of tire wear resistance have been continuously reported, and equipment for testing tire wear resistance has also been continuously emerging.

[0003] For example, a vehicle tire wear resistance testing device with announcement number CN219265719U is provided with a detachable friction plate on a tire wear resistance testing conveyor. The friction plate is adapted to the T-strip and the T-slot, which can prevent the friction plate from falling off and can be easily replaced by plugging and unplugging. By using different types of friction plates, tire testing of different friction media can be realized.

[0004] However, the tire mounting frame of the device can only move parallel to the tire wear resistance test conveyor. The simulated tire use condition is relatively single, and the wear condition of the tire when subjected to lateral force cannot be simulated, and further testing requirements cannot be met. In addition, the distance between the tire mounting frame and the tire wear resistance test conveyor is not easy to adjust.

[0005] Therefore, the present application provides a tire wear resistance testing device to meet the demand. Utility Model Content

[0006] In view of this, the purpose of this application is to provide a tire wear resistance testing device, which can enrich the test dimensions of tire wear resistance by applying lateral force to the tire, simulate actual usage conditions, and comprehensively test the tire wear resistance performance data.

[0009] Preferably, a groove is provided on the top surface of the frame, the roller shaft passes through the vertical part of the frame, and the roller shaft is rotatably connected to the frame through a bearing;

[0010] A belt groove is provided at the end of the roller shaft, and a belt is sleeved in the belt groove of the roller shaft.

[0011] Preferably, the slide rail is fixedly connected to one side of the frame, a screw rod is passed through the interior of the slide rail, a servo motor 2 is fixedly connected to the end of the slide rail, and an output end of the servo motor 2 is fixedly connected to the screw rod;

[0012] The screw rod is arranged through the column.

[0013] Preferably, a strip-shaped hole is opened on the side wall of the column, and the sleeve is arranged through the strip-shaped hole;

[0014] The other end of the spring abuts against the top wall of the strip hole inside the column.

[0015] Preferably, the electric push rod 1 and the electric push rod 2 are parallel to each other, and the friction belt is arranged parallel to the electric push rod 1 and the electric push rod 2.

[0018] Compared with the prior art, this application has at least the following beneficial effects:

[0019] In the above scheme, by arranging the sleeve, the electric push rod 1, the electric push rod 2, the connecting piece and the mounting plate, the electric push rod 1 and the electric push rod 2 are synchronously adjusted to make them extend or contract synchronously, so that the tire is pulled by the lateral force, thereby simulating the test condition of the tire in the actual use scenario, and by adjusting the position of the mounting plate relative to the friction belt, the friction coefficient is avoided to change due to the friction belt being contaminated by particles shed from the tire during the tire test, so that the uniformity of the test environment can be maintained during the test.

[0020] In the above scheme, by setting up a column, a spring and a sleeve, under the compression of the spring, the sleeve approaches the friction belt, so that the tire can fully maintain contact with the friction belt.

[0028] like Figure 1 , Figure 2 , Figure 3A tire wear resistance detection device shown in the embodiment of the present application includes a frame 1, a roller shaft 2 and a servo motor 3, roller shafts 2 are provided on both sides of the frame 1, the output end of the servo motor 3 is fixedly connected to the roller shaft 2, and also includes a friction belt 201 sleeved on the outer side of the roller shaft 2, a slide rail 4 arranged parallel to one side of the friction belt 201, a column 5 is arranged inside the slide rail 4, a sleeve 6 that can slide in the vertical direction is arranged on the column 5, a spring 601 is connected to the top of the sleeve 6, an electric push rod 602 is connected to the front end of the inner side wall of the sleeve 6, the other end of the electric push rod 602 is hinged to a connecting piece 603, the side wall of the connecting piece 603 is rotatably connected to a mounting plate 7, an electric push rod 2 604 is connected to the rear end of the inner side wall of the sleeve 6, and the other end of the electric push rod 2 604 is slidably connected to the connecting piece 603;

[0029] The friction coefficient of the friction belt 201 is set according to the friction coefficient of the road surface in the actual use environment. The roller 2 is driven by the servo motor 3 to rotate, so that the friction belt 201 rotates continuously, and the tire is installed on the mounting plate 7 through the wheel hub. The mounting plate 7 is located in the middle position of the friction belt 201 through the sliding of the column 5 relative to the slide rail 4.

[0030] Under the pressure of the spring 601, the sleeve 6 approaches the friction belt 201, so that the tire can fully keep in contact with the friction belt 201. The friction belt 201 moves relative to the tire to simulate the rolling state of the tire in actual use. The spring 601 can provide good downforce to simulate the wear of the tire under the condition of carrying weight.

[0031] By synchronously adjusting the electric push rod 1 601 and the electric push rod 2 604 to make them extend or contract synchronously, the tire is pulled by lateral force, simulating the test conditions of the tire in the actual usage scenario, and by adjusting the position of the mounting plate 7 relative to the friction belt 201, the friction coefficient change caused by the friction belt 201 being contaminated by particles shed from the tire during the tire test is avoided, so that the uniformity of the test environment can be maintained during the test.

[0032] In this embodiment, Figure 2-Figure 4 As shown: a groove is opened on the top surface of the frame 1, and the roller shaft 2 passes through the vertical part of the frame 1, and the roller shaft 2 is rotatably connected to the frame 1 through a bearing;

[0033] A belt groove is provided at the end of the roller shaft 2, and a belt 202 is sleeved in the belt groove of the roller shaft 2;

[0034] The groove at the top of the frame 1 can limit the position of the friction belt 201 to prevent the friction belt 201 from deviating from the roller shaft 2 , thereby ensuring the accuracy of the position of the friction belt 201 relative to the mounting plate 7 .

[0035] The slide rail 4 is fixedly connected to one side of the frame 1, a screw rod 401 is passed through the interior of the slide rail 4, a servo motor 2 402 is fixedly connected to the end of the slide rail 4, and the output end of the servo motor 2 402 is fixedly connected to the screw rod 401;

[0037] The column 5 is clamped inside the slide rail 4 , and the servo motor 402 drives the screw rod 401 to rotate. When the screw rod 401 rotates, it generates relative motion with the column 5 , thereby controlling the position of the column 5 relative to the friction belt 201 .

[0038] The side wall of the column 5 is provided with a strip hole, and the sleeve 6 is arranged through the strip hole;

[0039] The other end of the spring 601 abuts against the top wall of the strip-shaped hole inside the column 5;

[0040] The position of the sleeve 6 is limited by the strip-shaped holes so that the sleeve 6 can only move in the vertical direction relative to the column 5 , thereby ensuring the downward pressure of the tire on the friction belt 201 .

[0041] The electric push rod 1 602 and the electric push rod 2 604 are parallel to each other, and the electric push rod 1 602 and the electric push rod 2 604 are both parallel to the friction belt 201;

[0042] When the electric push rod 1 602 contracts and the electric push rod 2 604 extends, a certain angle is generated between the mounting plate 7 and the end surface of the sleeve 6, simulating the vehicle turning during the actual use of the tire, further enriching the simulation effect of the use condition, thereby meeting further comprehensive detection requirements.

[0043] A cylindrical boss is provided at the end of the connecting member 603, and the cylindrical boss of the connecting member 603 is rotatably connected to the mounting plate 7 via a bearing;

[0044] The side wall of the connecting member 603 is provided with a strip hole, and the ends of the electric push rod 1 602 and the electric push rod 2 604 are both arranged to pass through the strip hole;

[0045] The connecting member 603 can slide relative to the second electric push rod 604 on a horizontal plane, and the second electric push rod 604 cannot move in a vertical direction relative to the connecting member 603, thereby ensuring that the mounting plate 7 can be in stable contact with the friction belt 201.
