Description

Technical Field

[0001] This utility model relates to the field of tire durability testing, specifically a tire durability testing machine. Background Technology

[0002] With the increasing global emphasis on health and environmental protection in recent years, electric bicycles have become increasingly popular due to their convenience, energy efficiency, and environmental friendliness. China's electric bicycle industry has maintained rapid growth for over a decade, with annual production and sales reaching 35.05 million units in 2012. As of October 2013, the number of electric bicycles in China was projected to exceed 200 million. Electric bicycle tires are a crucial component, and their quality directly affects the performance of the bicycle. Durability testing of electric bicycle tires can verify the rationality of the tire structure and compound, provide experimental data for tire design, and shorten the tire development cycle.

[0003] After a tire is manufactured, samples need to be taken for durability testing, which requires the use of a testing machine. However, the testing machines currently in use can only test the tire under one type of road condition. But tires need to adapt to many different road conditions, which means that the current testing machines cannot meet the requirements. Therefore, if you want to test the tire under other road conditions, you need to change the testing machine or the test tire, resulting in low testing efficiency. Utility Model Content

[0014] 1. This utility model, by pulling the lever, drives the second sliding rod to move, thereby compressing the second spring, which in turn drives the limiting tooth to move, thus separating the limiting tooth from the limiting gear, allowing the limiting gear to rotate. Subsequently, the transmission plate is rotated, thereby driving the rotating roller to rotate, and simultaneously driving the auxiliary components and mounting components to rotate, so that the outer side of the test wheel abuts against the outer side of the tire, facilitating subsequent tire testing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-4 As shown, a tire durability testing machine includes a base 1. Two first upright plates 2 are fixedly connected to the top of the base 1. A PLC control device 3 is fixedly connected to the outer side of one of the first upright plates 2. A rotating assembly is arranged between the two first upright plates 2. The rotating assembly includes a rotating roller 4 fixedly connected between the two first upright plates 2. Two transmission plates 5 are rotatably connected to the outer side of the rotating roller 4. A limiting gear 14 is fixedly connected to the outer side of one of the transmission plates 5. A limiting tooth 15 is slidably connected inside the limiting gear 14. A pull rod 16 is fixedly connected to the top of the limiting tooth 15. A mounting frame 17 is slidably connected to the outer side of the pull rod 16. The pull rod 16 passes through the mounting frame 17. The bottom of the mounting frame 17 is fixedly connected to the top of the first upright plate 2. A second sliding rod 18 is fixedly connected to the top of the pull rod 16. The second sliding rod 18 passes through the mounting frame 17 and is slidably connected. A second spring 19 is fixedly connected between the top of the pull rod 16 and the bottom of the inner cavity of the mounting frame 17.

[0026] During operation, pulling the lever 16 moves the second slide bar 18, which in turn compresses the second spring 19, causing the limiting tooth 15 to move. This separates the limiting tooth 15 from the limiting gear 14, allowing the limiting gear 14 to rotate. Subsequently, rotating the transmission plate 5 causes the rotating roller 4 to rotate, simultaneously rotating the auxiliary components and the mounting components. This causes the outer side of the test wheel 13 to come into contact with the outer side of the tire 25, facilitating subsequent testing of the tire 25. This allows the tire 25 to be tested under various road conditions and improves experimental efficiency.

[0027] Furthermore, because the transmission plate 5 is rotatable, the position of the experimental wheel 13 can be changed at will, which allows the device to conduct experiments on tires 25 of different sizes, thereby improving the adaptability of the device.

[0028] The transmission plate 5 is provided with an auxiliary component on its outer side. The auxiliary component includes two mounting frames 6 fixedly connected to the outer side of the transmission plate 5. A square block 11 is slidably connected inside the mounting frame 6. A rotating shaft 12 is rotatably connected to the outer side of the square block 11. An experimental wheel 13 is fixedly connected to the end of the rotating shaft 12.

[0029] During operation, the square block 11 can be supported by the mounting frame 6, which in turn can support the rotating shaft 12 and the experimental wheel 13.

[0030] The mounting frame 6 is equipped with an installation component, which includes four first slide rods 7 that are slidably connected inside the mounting frame 6. The four first slide rods 7 are divided into two groups, and each group of first slide rods 7 has an E-type locking block 8 fixedly connected to its end. The E-type locking block 8 passes through the square block 11 and is slidably connected. The first slide rods 7 pass through the mounting frame 6 and are slidably connected.

[0031] The mounting assembly also includes a connecting plate 10 fixedly connected to the end of the first slide bar 7. The outer side of the connecting plate 10 is slidably connected to the inside of the mounting frame 6, and a first spring 9 is fixedly connected between the outer side of the E-type clip 8 and the inside of the mounting frame 6.

[0032] During operation, the square block 11 is placed on top of the E-type locking block 8, and then the E-type locking block 8 is pushed by the outer arc of the E-type locking block 8, thereby driving the first sliding rod 7 to move, which in turn compresses the first spring 9. When the bottom of the square block 11 abuts against the bottom of the inner cavity of the mounting frame 6, the E-type locking block 8 will enter the interior of the square block 11 under the rebound of the first spring 9, thereby restricting the position of the square block 11, which facilitates subsequent experiments on the tire 25.

[0033] Example 2

[0034] Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, the base 1 is provided with a transmission assembly at the top. The transmission assembly includes two second upright plates 20 fixedly connected to the top of the base 1. A motor 21 is fixedly connected to the outside of one of the second upright plates 20. A transmission rod 22 is fixedly connected to the transmission end of the motor 21. A mounting block 23 is fixedly connected to the end of the transmission rod 22. There are two mounting blocks 23.

[0035] During operation, the motor 21 drives the transmission rod 22 to rotate, which in turn drives the mounting block 23 to rotate, and in turn drives the tire 25 to rotate.

[0036] The second upright plate 20 is provided with a support assembly on its outer side. The support assembly includes a slide cylinder 26 fixedly connected to the outer side of the second upright plate 20. A third slide rod 27 is slidably connected inside the slide cylinder 26. One end of the third slide rod 27 is rotatably connected to the end of the second mounting block 23. A third spring 29 is fixedly connected between the other end of the third slide rod 27 and the inside of the slide cylinder 26. A limit rod 28 is fixedly connected inside the slide cylinder 26. The third slide rod 27 is slidably connected to the outside of the limit rod 28.

[0037] The mounting assembly also includes two transmission cylinders 24 that are slidably connected to the outside of the mounting block 23, and a tire 25 is fixedly connected between the two transmission cylinders 24.

[0038] During operation, by placing the transmission cylinder 24 outside one of the mounting blocks 23 and then pushing it, the third slide bar 27 is moved, thereby compressing the third spring 29. Then, the second transmission cylinder 24 is placed outside the second mounting block 23, thereby restricting the position of the tire 25 and facilitating the subsequent rotation of the tire 25.

[0039] The PLC control device 3 is electrically connected to the motor 21.

[0040] During operation, the motor 21 is controlled by the PLC control device 3, which ensures the normal operation of the device.

[0041] The working principle is as follows: by pulling the lever 16, the second sliding rod 18 is moved, which in turn compresses the second spring 19, thereby moving the limiting tooth 15. This causes the limiting tooth 15 to separate from the limiting gear 14, allowing the limiting gear 14 to rotate. Subsequently, the transmission plate 5 is rotated, which drives the rotating roller 4 to rotate, and at the same time drives the auxiliary components and mounting components to rotate. This causes the outer side of the test wheel 13 to abut against the outer side of the tire 25. Then, the limiting tooth 15 restricts the position of the limiting gear 14, which facilitates subsequent experiments on the tire 25. This allows the tire 25 to be tested under various road conditions and improves experimental efficiency.
