Description

Technical Field

[0001] The utility model relates to the technical field of tire detection, in particular to a tire wear identification device. Background Art

[0002] Automobile tires are one of the important components of an automobile. They are in direct contact with the road surface and, together with the automobile suspension, buffer the impact received during automobile driving, ensuring good riding comfort and driving smoothness of the automobile; ensuring good adhesion between the wheels and the road surface; improving the traction, braking performance and passability of the automobile; bearing the weight of the automobile; identifying the wear condition of the tire is an important basis for judging the tire state, usage condition and safety.

[0003] In the prior art, in the Chinese utility model patent document with the publication number CN217766123U, a tire wear detection device is provided. 1. By arranging components such as an installation box, a sleeve, a sliding rod, a spring, and a clamping block, the spring can drive the clamping block to quickly clamp the tire, and it can be applicable to tires of different sizes, solving the problem of inconvenient clamping of the tire during tire detection; 2. By arranging components such as a water pump and a water outlet pipe, the tire can be cleaned after the water pump accesses the water source, and at the same time, by arranging components such as a rotating shaft and a rotating wheel, the tire can be conveniently rotated to comprehensively clean the surface of the tire, making the observation more accurate, solving the problem that it is easy to affect the observation of the tire wear degree due to the tire being too dirty during tire detection.

[0004] Another example is the Chinese utility model patent document with the publication number CN219573819U, which provides a detection device for tire wear. 1. By designing a detector and a motor to drive the tire to rotate, the tire wear degree can be detected. At the same time, by rotating the rotating ring, the convex block on the connecting sleeve can be separated from the groove on the connecting block, which is convenient for disassembling and overhauling the detector and is more convenient; 2. Through the function of the designed air pump, the air pump can suck air through the air inlet, suck the dust and impurities attached to the outer surface of the tire, and remove the impurities. After the removal, the accuracy of the tire wear detection is higher. At the same time, through the function of the filter screen, the dust and impurities can be filtered to prevent environmental pollution.

[0005] However, such detection devices are mainly used for tire cleaning operations, and their detection functions still rely on traditional detection methods. When identifying tire wear, a lot of detection and identification data of the tire need to be obtained.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0030] Referring to Figure 1-7 , a tire wear identification device of the present utility model includes a base 1. A vertical wall 29 is provided at the top of the base 1. A top seat 2 is provided at the top of the vertical wall 29. A turntable 5 is provided on the front end face of the vertical wall 29. A chuck 4 for clamping the tire hub is provided on the front end face of the turntable 5. A slide seat 9 is provided above the chuck 4. The slide seat 9 is slidably mounted on the top seat 2 along the axial direction of the chuck 4. A tread wear measurement unit 8, a tire roundness measurement unit 10, and a tire sidewall measurement unit 11 are respectively provided on the chuck 4.

[0031] The tread depth of a tire directly affects the magnitude of the frictional force between the tire and the ground. The roundness of the tire affects the rolling effect when the tire rotates. Whether the tire sidewall bulges is used to judge whether the tire sidewall is deformed. The above three data all affect the safety of the tire during use and are the main identification items. When using this device to identify the wear degree of the tire, the tread wear measurement unit, the tire roundness measurement unit, and the tire sidewall measurement unit are respectively used to detect the above three data to identify the wear degree and safety of the tire.

[0032] The tire sidewall measurement unit 11 includes a sidewall measurement seat 15 slidably mounted on the slide seat 9 along the axis of the chuck 4. A bottom of the sidewall measurement seat 15 is provided with an L-shaped crank arm 17. A top of the L-shaped crank arm 17 is rotatably connected to the sidewall measurement seat 15. A first roller 14 is provided on a bottom of the L-shaped crank arm 17 near one side of the chuck 4. The first roller 14 is rotatably provided in a horizontal direction.

[0033] During use, according to the different tire widths, the position of the slide seat 9 is adjusted. The slide seat 9 drives the first roller 14 to stick to the tire sidewall. When there is a bulging phenomenon, the height of the bulging position is higher than the height of the normal tire sidewall, pushing up the first roller 14 and the L-shaped crank arm 17. By observing whether the first roller 14 is pushed up, it is judged whether there is a bulging phenomenon on the tire sidewall.

[0034] A first chute 7 is formed in the slide seat 9. A third screw 18 is arranged inside the first chute 7. The third screw 18 is rotatably mounted in the first chute 7. The third screw 18 is threadedly connected to the sidewall measurement seat 15. A front end of the third screw 18 extends outside the slide seat 9. Both ends of the sidewall measurement seat 15 are provided with first sliders 12 slidably connected to an inner wall of the first chute 7.

[0035] The slide seat 9 is slidably mounted in the first chute 7 through the first slider 12. By turning the third screw 18, the third screw 18 drives the slide seat 9 to move forward or backward along the axial direction of the chuck 4, thereby adjusting the position of the first roller 14 to fit the tire sidewall.

[0036] A swing groove 16 with a downward opening is formed at a bottom of the sidewall measurement seat 15. A ratchet 19 rotatable in a front-back direction is arranged inside the swing groove 16. A pawl 20 is arranged on one side of the ratchet 19. One end of the pawl 20 away from the ratchet 19 is connected to a pin shaft 13. The pin shaft 13 is rotatably mounted on the sidewall measurement seat 15. A coil spring is mounted on the pin shaft 13. One end of the pin shaft 13 extends outside the sidewall measurement seat 15. A bottom of the ratchet 19 is connected to a top of the L-shaped crank arm 17. When the pawl 20 meshes with the ratchet 19, the L-shaped crank arm 17 can only rotate forward.

[0037] Under normal circumstances, for a tire vertically clamped on the chuck 4, its sidewall is also vertical. Therefore, during use, the pin shaft 13 is rotated to separate the pawl 20 from the ratchet wheel 19, and the L-shaped crank arm 17 is in a vertical state. Moreover, the first roller 14 is in contact with the sidewall of the tire. Then, the pawl 20 and the ratchet wheel 19 are meshed normally. When there is a bulge on the sidewall of the tire, the bulge position will lift the first roller 14 and the L-shaped crank arm 17 to rotate forward. The cooperation between the ratchet wheel 19 and the pawl 20 enables the first roller 14 and the L-shaped crank arm 17 after forward rotation to maintain the rotated position and remain in a lifted state, facilitating the observation of whether the first roller 14 is lifted to determine whether there is a bulge on the sidewall of the tire.

[0038] The tire roundness measurement unit 10 includes a tire roundness measurement seat 21 slidably mounted on the slide base 9 in the vertical direction. Limiting mechanisms are arranged on both sides of the tire roundness measurement seat 21. A roller frame 25 is arranged at the bottom of the tire roundness measurement seat 21, and a second roller 24 is rotatably arranged at the bottom of the roller frame 25.

[0039] During use, the height of the tire roundness measurement seat 21 is adjusted so that the second roller 24 abuts against the circumferential surface of the tire. When the tire rotates, observe whether the tire roundness measurement seat 21 slides up and down or bounces to judge the roundness of the tire.

[0040] The limiting mechanism includes a guide groove 23 opened on the sidewall of the tire roundness measurement seat 21 in the vertical direction. The guide groove 23 is an oblong groove, and a guide block 22 is slidably arranged in the guide groove 23. One end of the guide block 22 away from the tire roundness measurement seat 21 is fixedly connected to the slide base 9.

[0041] When the tire roundness measurement seat 21 slides on the slide base 9 in the vertical direction, the guide block 22 and the guide groove 23 cooperate to prevent the tire roundness measurement seat 21 from sliding out of the slide base 9 upward or downward.

[0042] A marking mechanism is arranged on one side of the tire roundness measurement seat 21. The marking mechanism includes a vertical plate 26 arranged in front of the tire roundness measurement seat 21. A fourth screw 27 is threadedly connected to the vertical plate 26. The fourth screw 27 penetrates through the vertical plate 26. A marking pen 28 is arranged at one end of the fourth screw 27 close to the tire roundness measurement seat 21, and the tip of the marking pen 28 abuts against the sidewall of the tire roundness measurement seat 21.

[0043] When the difference between the maximum and minimum radii of the tire is within a specified range, it is reasonable. When the difference between the maximum radius and the minimum radius is too large, when the maximum radius rotates to the top of the tire, it will push the second roller 24 and the tire circle measuring seat 21 upward. When the minimum radius rotates to the top of the tire, the second roller 24 and the tire circle measuring seat 21 will move downward under their own weight. When the tire circle measuring seat 21 moves up and down, the marker pen 28 will draw scale lines on the surface of the tire circle measuring seat 21. According to the length of the scale lines, it is judged whether the difference between the maximum radius and the minimum radius of the tire is within the specified range, and the influence of the roundness of the tire on the tire performance, state, and safety is identified.

[0044] The tread wear measurement unit 8 includes a tread measurement seat slidably mounted on the slide base 9 in the vertical direction, and a tire tread depth gauge is installed at the bottom of the tread measurement seat.

[0045] A second screw 6 is installed in front of the tread measurement seat. The second screw 6 is threadedly connected to the slide base 9. The rear end of the second screw 6 abuts against the front wall of the tread measurement seat. By turning the second screw 6, the movement or fixation of the tread measurement seat can be adjusted. The tire tread depth gauge can be a digital display type tire tread depth gauge. When in use, first adjust the height of the tread measurement seat so that the main scale probe of the tire tread gauge abuts against the bottom of the tire tread groove, and the measurement surface is flush with the tire tread surface. Slowly rotate the tire to detect the tread wear degree of the tire and identify the usage condition of the tire tread.

[0046] A first screw 3 is arranged inside the slide base 9. The rear end of the first screw 3 is rotatably connected to the top seat 2. The first screw 3 penetrates through the slide base 9 and is threadedly connected to the slide base 9. The front end of the first screw 3 extends outside the slide base 9.

[0047] Second sliders and second chutes are arranged on both sides of the slide base 9. The second sliders and the slide base 9 are of an integrally formed structure. The second chutes are opened on the top seat 2. The rear end of the first screw 3 is rotatably connected to the top seat 2. When the first screw 3 is rotated, the first screw 3 drives the slide base 9 to move forward or backward, so as to drive the tread wear measurement unit 8, the tire roundness measurement unit 10, and the tire sidewall measurement unit 11 to move forward or backward synchronously for the wear of tires with different widths.

[0048] Working principle: When in use, the hub of the tire is clamped on the chuck 4, and then the positions of the tread wear measurement unit 8, the tire roundness measurement unit 10, and the tire sidewall measurement unit 11 are adjusted so that the main scale probe of the tire tread depth gauge abuts against the tread groove of the tire, the second roller 24 abuts against the circumferential surface of the tire, and the first roller 14 is placed on the sidewall of the tire. Start the turntable to drive the tire to rotate, and measure the tread wear degree of the tire, the roundness of the tire, and the flatness of the tire sidewall, and whether there is a bulge phenomenon, so as to identify the wear condition of the tire.
