[0031] Please see Figure 1-8 This utility model provides a technical solution:

[0032] A vehicle tire reliability testing device includes a test wheel position control component 1.

The movable plate 43 is installed inside the fixing cylinder 36.

[0033] As a further implementation of this solution, the test wheel position control component 1 includes a base plate 11. A rail groove 12 is formed at the upper end of the base plate 11. A first hydraulic telescopic rod 13 is fixedly connected to the right side of the rail groove 12, and a rail plate 14 is fixedly connected to the left side of the first hydraulic telescopic rod 13. The rail plate 14 is slidably connected to the inner side of the rail groove 12. An electric telescopic rod 15 is fixedly connected to the top of the rail plate 14, and a vertical plate 16 is fixedly connected to the top of the electric telescopic rod 15. There are two vertical plates 16. A shaft hole is formed on the inner side of the vertical plate 16, and a bearing is fixedly connected to the inner side of the shaft hole of the vertical plate 16. The vertical plate 16 is rotatably connected to the test wheel body 17 through the bearing. The vertical plates 16 are distributed at the left and right ends of the test wheel body 17. With the above settings, it can quickly adapt to different tire sizes or testing requirements, improve the versatility and ease of operation of the testing device, and the stability of this structure also provides a reliable support foundation for the subsequent testing process.

[0034] As a further implementation of this solution, the drive support assembly 2 includes a frame 21 with a shaft hole on its inner side.

With the above configuration, the fixed assembly 3, the pre-installed assembly 4, the tire body 5, and the wheel hub 6 rotate as a whole when driven by the drive support assembly 2, thereby achieving the effect of tire endurance testing. This configuration makes the entire power transmission system more compact and efficient, reduces power loss, and improves the operating efficiency of the testing device.

[0035] As a further implementation of this solution, the protective ring 33 is in the shape of a ring and is fitted on the left end of the fixed cylinder 36. The inner side of the protective ring 33 fits against the outer side of the fixed cylinder 36. A gap is provided between the ear seat 35 and the fixed plate 31. The first assembly groove 37 is embedded in the interior of the protective ring 33. The fixed protrusion 44 is fixed on the inner side of the fixed cylinder 36. Through the above settings, not only can the components be fixed and limited, but also the coordination and stability of the movement between the components can be guaranteed. This prevents the detection failure or device damage caused by the loosening or detachment of the components during the detection process, thereby improving the overall performance and service life of the detection device.

[0036] As a further implementation of this solution, both the first assembly groove 37 and the second assembly groove 38 penetrate the upper end of the fixed cylinder 36. A groove is formed on the inner side of the fixed cylinder 36, and the groove of the fixed cylinder 36 is flush with the front and rear ends of the first assembly groove 37. The left end of the fixed cylinder 36 has a through-hole structure. The outer side of the auxiliary clamping plate 34 fits against the inner side of the groove of the fixed cylinder 36. A protrusion 44 is fixed to the right end of the auxiliary clamping plate 34. The right end of the auxiliary clamping plate 34 is tightly fitted to the left end of the movable disk 43 through two sets of protrusions 44. The movable disk 43 is cylindrical in shape. The left and right ends of the movable disk 43... All are fixed with protrusions 44 and fixed support pillars 41 embedded in the inner side of the second assembly groove 38. The fixed support pillars 41 extend out of the right end of the fixed cylinder 36. The tire body 5 is installed on the outer side of the wheel hub 6. Through the above configuration, the cylindrical shape of the movable disc 43 gives it good structural stability and strength, preventing it from loosening or falling off during movement. This provides a solid foundation for the installation and inspection of the tire body 5. At the same time, the design of installing the tire body 5 on the outer side of the wheel hub 6 makes it easy to install and remove the tire, improving inspection efficiency and operational convenience.

[0037] Workflow: When performing durability testing on the tire body 5, first install the tire body 5 and the wheel hub 6, align the existing screw holes of the wheel hub 6 with the reserved screw holes 42, and fix the wheel hub 6 to the fixed support 41 with bolts. After fixing, fix the pre-installed component 4 to the fixed component 3, align the movable plate 43 with the first mounting groove 37, and slide the movable plate 43 through the first mounting groove 37 into the interior of the fixed cylinder 36. At this time, the fixed support 41 is embedded in the interior of the second mounting groove 38. When the bottom end of the fixed support 41 and the bottom end of the movable plate 43 are both at the lower end of the fixed cylinder 36... After the inner sides are fitted together, the fixed support 41 and the movable plate 43 are pulled forward. After the movable plate 43 is in close contact with the protrusion 44 on the inner right side of the fixed cylinder 36, the movable plate 43 moves away from the first assembly groove 37. The second hydraulic telescopic rod 32 is activated to drive the fixed cylinder 36 to move backward. The fixed cylinder 36 drives the pre-installed assembly 4, the tire body 5, and the wheel hub 6 to move to the right. When the protrusion 44 on the left side of the movable plate 43 is in close contact with the protrusion 44 on the right side of the auxiliary clamping plate 34, the left end of the fixed cylinder 36 slides into the inside of the protective ring 33. The first assembly groove 37 moves into the inside of the protective ring 33, and the first assembly groove 37 moves into the inside of the protective ring 33. The protective ring 33 prevents the pre-installed component 4 from accidentally detaching from the fixing component 3. Simultaneously, the auxiliary clamp 34 and the fixing cylinder 36 press against each other to secure the pre-installed component 4. Then, the test wheel body 17 is brought into contact with the tire body 5. The first hydraulic telescopic rod 13 is activated to push the rail plate 14 to the left. The electric telescopic rod 15 then drives the upright plate 16 and the test wheel body 17 upwards until the test wheel body 17 is in contact with the outer side of the tire body 5. This method is applicable to tire testing of various sizes. Then, the drive motor 22 is activated to rotate the built-in shaft 24. The mounting column 24 rotates inside the stand 21 via ball bearing 23. The built-in mounting column 24 drives the fixed plate 31 on the left to rotate, thereby driving the tire body 5 and wheel hub 6 to rotate through the fixing component 3 and the pre-installation component 4. Through the friction between the tire body 5 and the test wheel body 17, the process of driving a car is simulated, thus realizing the work of testing the durability of the tire body 5. Based on the above principles, the device avoids the traditional method of raising the entire vehicle and then contacting the tire with the test wheel body 17. This method avoids the use of large lifting equipment, which not only reduces the cost of use, but also improves the safety of testing.

[0038] 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.
