Description

Technical Field

[0001] This utility model relates to the field of tire performance testing technology, and in particular to a device for testing the wear resistance of automobile tires. Background Technology

[0002] Car 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, work to mitigate the impacts the car experiences while driving, ensuring good ride comfort and smooth driving, maintaining good adhesion between the wheels and the road surface, improving the car's traction, braking, and passability, and bearing the weight of the car. When conducting wear resistance testing on car tires, a wear resistance testing machine is required.

[0003] A search of Chinese Patent Publication No. CN220932682U reveals a tire abrasion resistance testing machine for automobiles, comprising a tire fixing rotator and a metal base. The tire fixing rotator is fixedly mounted on the upper middle position of the metal base. A car tire workpiece is mounted on the upper end of the tire fixing rotator. A locking end cap is mounted on the tire fixing rotator above the car tire workpiece. A right-side abrasion resistor is mounted on the metal base to the right of the car tire workpiece, and a control panel is mounted at the front end of the right-side abrasion resistor. A left-side detector is mounted on the metal base to the left of the car tire workpiece. The right-side abrasion resistor, the tire fixing rotator, and the left-side detector are electrically connected to the control panel via connecting wires. The right-side abrasion resistor includes a telescopic adjustment cylinder, a concave outer shell, an intermediate shaft, an abrasion resistance testing wheel, and a telescopic cylinder body. The tire is driven to rotate by the tire fixing rotator, and during the rotation, the tire abuts against the abrasion resistance testing wheel to test the tire's abrasion resistance.

[0004] Tires are made of rubber. During the wear resistance test, the tires are subjected to a lot of friction, which generates heat and easily releases a pungent odor, causing discomfort to the testers. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-4As shown, a tire wear resistance testing device includes a base plate 1. A mounting base 201 is fixedly connected to the top of the base plate 1. A mounting groove is provided inside the mounting base 201. A rotary motor 202 is bolted to the mounting groove. A placement plate 203 is fixedly connected to the output end of the rotary motor 202. A groove is provided on the top of the mounting base 201. The placement plate 203 is rotatably connected to the groove. The top of the placement plate 203 extends out of the mounting base 201. A tire 3 is placed on the top of the placement plate 203. The diameter of the placement plate 203 is smaller than the diameter of the tire 3, so that the edge of the tire 3 is exposed to avoid affecting the test.

[0025] A fixing component is provided above the tire 3. The fixing component includes a screw 401 fixedly connected to the top of the placement tray 203. A locking pressure plate 402 is threadedly connected to the screw 401. Several circumferentially arranged levers 403 are fixedly connected to the outer wall of the locking pressure plate 402. The screw 401 passes through the middle of the tire 3. The locking pressure plate 402 is screwed downward by the levers 403, so that the locking pressure plate 402 presses against the tire 3, thereby fixing the tire 3 on the placement tray 203.

[0026] A detection mechanism is provided on one side of the tire 3. The detection mechanism includes a mounting bracket 501 bolted to the top of the base plate 1. The mounting bracket 501 is L-shaped. A hydraulic cylinder 502 is fixedly connected to the side of the mounting bracket 501 closest to the tire 3. A mounting shell 503 is fixedly connected to the other end of the hydraulic cylinder 502. The mounting shell 503 is U-shaped with its opening facing the tire 3. A wear-resistant detection wheel 504 is rotatably connected between the upper and lower inner walls of the mounting shell 503. A detector (not shown in the figure) is provided on the side of the tire 3 away from the detection mechanism. The detector includes a fixing plate bolted to the top of the base plate 1. A hollow sleeve plate is bolted to the top of the fixing plate. A digital micrometer is connected to the hollow sleeve plate by a locking bolt. Loosening the locking bolt makes it easy to adjust the position of the digital micrometer so that it can easily contact the tire 3. When the tire 3 wears, the change in wear thickness can be easily detected by the digital micrometer. The specific structure and usage of the detector are prior art disclosed in the patent with publication number CN220932682U, and will not be described in detail.

[0027] A purification mechanism is installed above the testing mechanism. The purification mechanism includes a purification box 601, which is bolted to the top of the mounting frame 501. An air inlet pipe 602 is fixedly connected to one side of the purification box 601, and an air collection hood 603 facing the tire 3 is fixedly connected to the other end of the air inlet pipe 602. An activated carbon adsorption layer 604 is provided between the inner walls of the purification box 601, and an air outlet is opened on the side of the purification box 601 away from the air inlet pipe 602.

[0028] The purification box 601 is also equipped with a negative pressure mechanism, which is used to draw air into the purification box 601. The negative pressure mechanism includes a rotating shaft 701 rotatably connected to the side wall of the purification box 601 away from the air inlet pipe 602. Several circumferentially arranged fan blades 702 are fixedly connected to the rotating shaft 701. The fan blades 702 are located inside the purification box 601.

[0029] The negative pressure mechanism also includes a power assembly, which uses the kinetic energy of the rotary motor 202 to drive the rotating shaft 701 to rotate. The power assembly includes a first drive shaft 703 rotatably connected to the top of the base plate 1, a gear ring 704 fixedly connected to the outer wall of the placement tray 203, a drive gear 705 fixedly connected to the first drive shaft 703, the drive gear 705 meshing with the gear ring 704, a second drive shaft 706 rotatably connected to the top of the purification box 601, a belt 707 connecting the second drive shaft 706 and the first drive shaft 703 via a pulley, a driving bevel gear 708 fixedly connected to the second drive shaft 706, and a driven bevel gear 709 fixedly connected to the end of the rotating shaft 701 extending out of the purification box 601, the driven bevel gear 709 meshing with the driving bevel gear 708.

[0030] Working principle: In use, the tire 3 is placed on top of the placement plate 203 after passing through the screw 401. The locking plate 402 is screwed down until the tire 3 is pressed against the placement plate 203. The hydraulic cylinder 502 is controlled to make the wear-resistant detection wheel 504 contact the tire 3. The rotary motor 202 is started, which drives the placement plate 203 to rotate the tire 3. The wear-resistant detection wheel 504 rubs against the tire 3. At the same time, the rotation of the placement plate 203 drives the gear ring 704 to rotate. The gear ring 704 meshes with the drive gear 705, thereby driving the drive gear 705 to drive the first drive shaft 703 to rotate. The transmission between the wheel and the belt 707 drives the second drive shaft 706 to rotate. The second drive shaft 706 drives the active bevel gear 708 to rotate. The active bevel gear 708 meshes with the driven bevel gear 709, thereby driving the driven bevel gear 709 to drive the rotating shaft 701 to rotate. The rotating shaft 701 drives the fan blade 702 to rotate, creating a negative pressure inside the purification box 601. This draws air near the wear-resistant testing wheel 504 into the purification box 601. The activated carbon adsorption layer 604 adsorbs the irritating odor in the air to avoid causing discomfort to the testing personnel. The wear of the tire 3 is detected by a digital dial indicator, thus reflecting the wear resistance of the tire 3.
