Description

Technical Field

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

[0002] A car is a common means of transportation in modern times, mainly used for commuting and transport. According to the "Terms and Definitions of Motor Vehicles and Trailers", a motor vehicle is defined as: a non-rail-borne vehicle driven by a power source with four or more wheels, mainly used for: carrying passengers and / or goods; towing vehicles carrying passengers and / or goods; and for special purposes. As a car is constantly in motion, its tires are constantly wearing down. Excessively worn tires have insufficient grip and are prone to blowouts, which can lead to traffic accidents. Therefore, tire wear resistance needs to be tested after production.

[0003] A tire wear resistance testing device for new energy vehicles, authorized by announcement number CN209961495U, includes a base. The upper end of the base is provided with a clamping component for holding and fixing the tire. The clamping component includes a mounting column rotatably mounted on the upper surface of the base and a first fixing plate mounted on its upper end. The mounting column is connected to a driving component that drives its rotation. The clamping component also includes a mounting plate connected to the left support wall of the base and a second fixing plate positioned below it, corresponding to the first fixing plate. The second fixing plate and the first fixing plate together form a clamping end for holding the component. This invention improves upon the shortcomings of existing devices, facilitating the adjustment of the pressure exerted by the friction wheel on the tire, and also adjusting the viscous resistance during the rotation of the friction wheel, thus meeting the tire testing requirements. It also increases friction loss during tire testing, shortens the testing cycle, and is highly practical.

[0004] As shown in the above equipment, the existing automobile tire wear resistance testing device has a tire fixing component, which makes it easy to adjust the extrusion pressure and rotational viscous resistance of the friction wheel on the tire to meet the testing requirements. It also has high friction loss, short testing cycle and strong practicality. However, it is difficult to adapt to different tire specifications, cannot flexibly adjust the clamping state, has poor versatility and narrow application range. Utility Model Content

[0016] 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.

[0017] See Figures 1-4 This utility model provides the following two technical solutions: First embodiment: A vehicle tire abrasion resistance testing device, including an L-shaped base 1, and further comprising: Fixed adjustment structure 7 is set above the L-shaped base frame 1 to accommodate clamping different car tires; The conveying and adjusting structure 5 is set above the L-shaped base frame 1 and is used to transport the car tire clamped by the fixing and adjusting structure 7 to the inspection area for inspection.

[0018] The fixed adjustment structure 7 includes a slide 71, which is located above the L-shaped base frame 1.

A fixing groove plate 77 is connected to the mounting plate 73 through the auxiliary fixing component 75. The fixing groove plate 77 and the fixing protrusion 76 are slidably connected.

[0019] The auxiliary fixing component 75 includes a circular groove box 751, a slide rail 752 rotatably connected to the circular groove box 751, a turntable 753 slidably connected to the outer wall of the slide rail 752, a limiting straight groove 754 formed on the outer wall of the turntable 753, a slide rod 755 slidably connected to the outer wall of the turntable 753, a connecting arc plate 756 fixedly connected to one end of the slide rod 755, the outer wall of the connecting arc plate 756 fixedly connected to the fixed protrusion plate 76, the outer wall of the connecting arc plate 756 fixedly connected to the fixed groove plate 77, an arc groove plate 757 rotatably connected to the outer wall of the turntable 753 for limiting the movement of the slide rod 755, a sealing plate 758 fixedly connected to the outer wall of the circular groove box 751, a servo motor B759 fixedly connected to the outer wall of the sealing plate 758, and the output end of the servo motor B759 fixedly connected to the arc groove plate 757 through a coupling.

[0020] The automotive tire abrasion resistance testing device is equipped with a fixed adjustment structure 7. The servo motor B759 drives the arc groove plate 757 to rotate, which, together with the turntable 753, limits the straight groove 754 and slide rod 755, thereby driving the connecting arc plate 756, the fixed protrusion plate 76, and the fixed groove plate 77 to move flexibly. It can adapt to tires of different specifications, and the clamping process is stable and smooth. The clamping force and position can be precisely adjusted to ensure that the tire is firmly fixed, providing a reliable clamping basis for abrasion resistance testing and improving the adaptability and stability of the test.

[0021] The second embodiment differs from the first embodiment in that: the conveying adjustment structure 5 includes a grooved plate A51, which is fixedly installed on the outer wall of the L-shaped base frame 1. A threaded rod 52 is rotatably connected to the outer wall of the grooved plate A51, and a hydraulic platform A54 is threadedly connected to the outer wall of the threaded rod 52. A limit rod A53 is fixedly connected to the outer wall of the grooved plate A51 for limiting the movement of the hydraulic platform A54.

[0022] One end of the grooved plate A51 is fixedly connected to a drive motor B6, and the output end of the drive motor B6 is fixedly connected to the threaded rod 52 through a coupling.

[0023] This automotive tire abrasion resistance testing device is equipped with a conveying and adjusting structure 5. Drive motor B6 rotates the threaded rod 52 on the grooved plate A51, which, in conjunction with the limiting rod A53, allows the hydraulic table A54 to move stably. Drive motor A58 rotates the bidirectional lead screw 56 on the grooved plate B55, which, in conjunction with the limiting rod B57, drives the slide 71 to move precisely. This device efficiently transports clamped tires to the testing area. Through multi-component coordination and limiting, it achieves stable and precise conveying and adjusting, ensuring a continuous tire testing process and improving the automation and accuracy of the testing work.

[0025] In use, the tires are moved using the casters 8 as an auxiliary device. In the conveying and adjusting structure 5, the drive motor B6 starts, causing the threaded rod 52 on the grooved plate A51 to rotate. Because the hydraulic table A54 is threadedly connected to the threaded rod 52 and is limited by the limiting rod A53, the hydraulic table A54 moves along the grooved plate A51. At the same time, the drive motor A58 starts, causing the bidirectional lead screw 56 on the grooved plate B55 to rotate. The slide 71 is threadedly connected to the bidirectional lead screw 56 and limited by the limiting rod B57, and the slide 71 moves accordingly to transport the tires. In the fixed adjusting structure 7, the servo motor A74 operates, driving the auxiliary fixing component 75 to work via the coupling. In the auxiliary fixing component 75, the servo motor B759 starts, causing the arc groove plate 757 to rotate. The slide rod 755 slides along the limiting straight groove 754 on the arc groove plate 757 and the turntable 753, causing the connecting arc plate 756 to move, thereby allowing the fixing convex plate 76 to cooperate with the fixing groove plate 77 to clamp different tires. Finally, the tire is transported to test stand 3 and comes into contact with friction wheel 4 to conduct wear resistance testing.
