Description

Technical Field

[0001] This utility model relates to the technical field of tire testing equipment, specifically a tire wear resistance testing device. Background Technology

[0002] Tires are one of the most important components of a car. They come into direct contact with the road surface and, together with the car's suspension, mitigate the impact of driving, ensuring good ride comfort and smoothness. They also ensure good adhesion between the wheels and the road surface, improving the car's traction, braking, and handling. Bearing the weight of the car, the crucial role of tires is increasingly recognized. The tire mixing process involves mixing raw materials such as carbon black, natural or synthetic rubber, oil, additives, and accelerators in a mixer to produce the rubber compound. This process is sometimes compared to kneading dough in cooking. Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and extreme temperatures during driving. Therefore, they must possess high load-bearing capacity, traction, and cushioning performance. Simultaneously, they must have high wear resistance and flexural strength, as well as low rolling resistance and heat generation. To test tire durability, finished tires are subject to random sampling to monitor quality and ensure safe use, hence their widespread use.

[0003] Existing tire abrasion testing equipment requires assembling and fixing the tire to the vehicle using bolts and nuts, and then testing the tire's quality by driving the vehicle. This installation and operation is cumbersome, time-consuming, and labor-intensive, which is not conducive to the abrasion resistance testing work. In addition, tires need to be tested on different road conditions, but only one type of road condition can be tested at a time, resulting in generally poor test results.

[0004] Patent CN218584562U discloses a tire abrasion resistance testing device, including a main body. A rotating shaft is rotatably connected to the inner front surface of the main body. A disc is mounted on the outer front surface of the rotating shaft, and a mounting bolt is threaded onto the inner rear surface of the disc. A threaded rod is rotatably connected to the inner right side surface of the main body, and an adjusting seat is threaded onto the outer wall of the rotating rod. A rotating platform is mounted on the inner upper surface of the adjusting seat. This tire abrasion resistance testing device uses mounting bolts on both sides to move a rubber pad against the tire surface for positioning and fixation. Then, a first servo motor drives the rotating shaft to rotate, allowing the tire to rotate. This eliminates the need to mount the tire on a car for testing, saving time and effort. The rotating platform adjusts the position of four sets of friction wheels used to simulate different road conditions, allowing for timely adjustment of tire testing to different road conditions and improving the efficiency of tire testing.

[0005] However, the device requires rotating four sets of mounting bolts separately when fixing the tire, which is a rather cumbersome operation. In addition, fixing the rotating table in the device also requires tightening multiple positioning bolts, making the operation process quite complicated. Utility Model Content

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a tire wear resistance testing device, comprising a device base plate, a horizontal sliding groove on the device base plate, a sliding frame slidably installed in the horizontal sliding groove, a rotating frame rotatably installed on the sliding frame, a plurality of friction wheels spaced apart along the circumferential direction on the rotating frame, a rotating shaft protruding from the rotating frame, an adjusting handwheel installed at one end of the rotating shaft passing through the sliding frame, a mounting frame provided on the top of the device base plate, a rotating motor installed on the mounting frame, a mounting plate connected to the actuation output shaft of the rotating motor, a threaded rod threadedly connected to the mounting frame, a clamping plate rotatably installed at one end of the threaded rod, and an adjusting wheel provided at the other end of the threaded rod.

[0010] Preferably, both the abutting plate and the mounting plate are provided with a plurality of abutting blocks, which are made of rubber.

[0011] Preferably, a lead screw is rotatably installed in the horizontal slide groove, a sliding frame is threadedly connected to the lead screw, a servo motor is provided on the base plate of the device, and one end of the lead screw is installed on the action output shaft of the servo motor.

[0012] Preferably, a fixing block is installed on the sliding frame, and a reset slider is slidably installed inside the fixing block. One end of the reset slider is provided with a handle, and the other end of the reset slider is provided with a locking block.

[0013] Preferably, the fixing block has two mutually symmetrical guide grooves, and a guide block is slidably installed in the guide groove, and the guide block is installed on the reset slider.

[0014] Preferably, a return spring is arranged in the guide groove, with one end of the return spring abutting against the inner wall of the guide groove and the other end of the return spring abutting against the guide block.

[0015] Preferably, the surface roughness of the multiple friction wheels on the rotating frame is different.

[0016] Compared with the prior art, this utility model provides a tire wear resistance testing device with the following advantages: This utility model, through the cooperation of a rotating frame, a sliding frame, a mounting plate, and a clamping plate, allows for the following operation: The tire is placed between the clamping plate and the mounting plate, and the adjusting wheel is rotated to drive the threaded rod. This allows the clamping plate to move horizontally towards the mounting plate via the threaded connection, thus securing the tire between the mounting plate and the clamping plate. The rotating frame then rotates along the sliding frame, moving the friction wheel corresponding to the simulated road surface to the tire side. The position of the rotating frame is restricted by the locking blocks and slots. A servo motor drives the lead screw to rotate, and the threaded connection causes the sliding frame to bring the friction wheel on the rotating frame into contact with the tire. The rotating motor then drives the tire to rotate and perform wear resistance testing on the friction wheel. This allows for wear resistance testing of tires under different road conditions. The overall operation is simple and quick, simplifying the steps and improving work efficiency. Attached Figure Description

[0026] Please see Figure 1-5 A tire abrasion resistance testing device includes a device base plate 1, a horizontal slide groove 2 on the device base plate 1, a sliding frame 3 slidably installed in the horizontal slide groove 2, a rotating frame 6 rotatably installed on the sliding frame 3, a plurality of friction wheels 7 arranged at intervals along the circumferential direction on the rotating frame 6, a rotating shaft 20 protruding from the rotating frame 6, an adjusting handwheel 13 installed at one end of the rotating shaft 20 passing through the sliding frame 3, a mounting frame 8 provided on the top of the device base plate 1, a rotating motor 9 installed on the mounting frame 8, a mounting plate 14 connected to the actuation output shaft of the rotating motor 9, a threaded rod 17 threadedly connected to the mounting frame 8, a clamping plate 11 rotatably installed at one end of the threaded rod 17, and an adjusting wheel 10 provided at the other end of the threaded rod 17.

[0027] By cooperating with the rotating frame 6, sliding frame 3, mounting plate 14, and clamping plate 11, the tire can be placed between the clamping plate 11 and the mounting plate 14 during use. Rotating the adjusting wheel 10 drives the threaded rod 17 to rotate, allowing the clamping plate 11 to move horizontally towards the mounting plate 14 via the threaded connection. This achieves the purpose of clamping the tire between the mounting plate 14 and the clamping plate 11. Then, by rotating the rotating frame 6 along the sliding frame 3, the friction wheel 7 corresponding to the simulated road surface moves to the side of the tire. The position of the rotating frame 6 is restricted by the locking block 19 and the locking groove 16. The servo motor 5 drives the lead screw 4 to rotate, and the threaded connection causes the sliding frame 3 to bring the friction wheel 7 on the rotating frame 6 into contact with the tire. At this point, the rotating motor 9 drives the tire to rotate and perform a wear resistance test with the friction wheel 7. This allows the tire to undergo wear resistance testing under different road conditions. The overall operation is simple and quick, simplifying the operation steps and improving work efficiency.

[0028] Specifically, in this embodiment, both the abutting plate 11 and the mounting plate 14 are provided with a plurality of abutting blocks 12, which are made of rubber.

[0029] The rubber clamping block 12 can effectively clamp and fix the tire.

[0030] Specifically, in this embodiment, a lead screw 4 is rotatably installed in the horizontal slide groove 2, a sliding frame 3 is threadedly connected to the lead screw 4, a servo motor 5 is provided on the device base plate 1, and one end of the lead screw 4 is installed on the action output shaft of the servo motor 5.

[0031] Through the cooperation of the lead screw 4 and the servo motor 5, the lead screw 4 can be rotated by the servo motor 5, and the sliding frame 3 can slide in the horizontal slide groove 2 through the threaded advance relationship.

[0032] Specifically, in this embodiment, a fixing block 15 is installed on the sliding frame 3, and a reset slider 18 is slidably installed in the fixing block 15. One end of the reset slider 18 is provided with a handle, and the other end of the reset slider 18 is provided with a locking block 19. Multiple locking slots 16 that are adapted to the locking blocks 19 are spaced apart along the circumferential direction on the rotating shaft 20. Two mutually symmetrical guide slots 21 are opened in the fixing block 15, and guide blocks 22 are slidably installed in the guide slots 21. The guide blocks 22 are installed on the reset slider 18.

[0033] By cooperating with the reset slider 18, guide block 22 and guide groove 21, the reset slider 18 can be moved within the fixed block 15 by the handle during use, so that the locking block 19 can be inserted into and removed from the slot 16. When the reset slider 18 moves, the guide block 22 can be moved along the guide groove 21 to limit the range of movement of the reset slider 18 and prevent the reset slider 18 from sliding out of the fixed block 15.

[0034] Specifically, in this embodiment, a reset spring 23 is arranged in the guide groove 21. One end of the reset spring 23 abuts against the inner wall of the guide groove 21, and the other end of the reset spring 23 abuts against the guide block 22.

[0035] By setting the reset spring 23, the reset spring 23 can be squeezed while the guide block 22 slides along the guide groove 21. Through the elastic potential energy of the reset spring 23, the reset slider 18 can be automatically reset when the force on the reset slider 18 is stopped. In the normal state, the reset spring 23 can keep the guide block 22 pressed against the inner wall of one side of the guide groove 21, so that the locking block 19 on the reset slider 18 can always be pressed against the locking groove 16 on the rotating shaft 20, thereby restricting the position of the rotating frame 6.

[0036] Specifically, in this embodiment, the surface roughness of the multiple friction wheels 7 on the rotating frame 6 is different.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
