[0038] In a preferred solution, the pressure sensor 10 is connected to the data collection module 5 .

[0039] In a preferred solution, a guide groove 7 is provided at the bottom of the groove 101 , and a transverse positioning protrusion 601 located in the guide groove 7 is provided at the bottom of the wheel clamp 6 .

[0040] In a preferred embodiment, the pressure sensor carrier plate 9 is located in the guide groove 7. A first rotating rod 8 is provided in the guide groove 7 and passes through the pressure sensor carrier plate 9 and the transverse positioning protrusion 601. The first rotating rod 8 is provided with two threaded sections 801 with opposite rotation directions. The two pressure sensor carrier plates 9 are located on the two threaded sections 801.

[0041] One end of the first rotating rod 8 passes through the outside of the base 1 and is provided with a first rotating handle 802 .

[0042] In a preferred embodiment, the wheel radial positioning mechanism 4 includes a fixed seat 12 with a slide groove, a slider 14 is provided in the slide groove of the fixed seat 12, and a horizontal and threaded second rotating rod 13 passes through the slider 14. A substrate 15 is provided on the top surface of the slider 14 and extends toward the base 1. A resistance wire sensitive grid and a cover sheet 16 covering the resistance wire sensitive grid are provided on the bottom surface of one end of the substrate 15.

[0043] The resistance wire sensitive grid is connected to the data collection module 5 via a lead wire.

[0044] In a preferred solution, one end of the second rotating rod 13 passes through the outside of the fixing seat 12 and a second rotating handle 131 is provided on the end.

[0045] In a preferred embodiment, two wheel support rods 17 are provided between the two wheel clamps 6 at the same level, one end of the two wheel support rods 17 passes through one of the wheel clamps 6, and a slot 171 is provided on the passing portion;

[0046] A U-shaped rod 18 is provided above one of the wheel splints 6, and the vertical portions on both sides of the U-shaped rod 18 are aligned with the two slots 171;

[0047] The wheel clamp 6 is further provided with two rod seats 19 for the vertical portions on both sides of the U-shaped rod 18 to pass through.

[0048] Example 2:

[0049] Based on Example 1, considering that a certain blocking area will be formed when the vehicle is located at the workstation, the following optimizations can be considered in the component design position:

[0050] The U-shaped rod 18 is arranged on a wheel clamping plate on one side close to the side vertical plate 2 to prevent obstruction when the vehicle is located at the work station, thereby affecting the manual adjustment operation of the U-shaped rod 18.

[0051] At the same time, the first turning handle 802 can also be arranged on a side close to the side vertical plate 2 to also prevent the vehicle from being blocked.

[0052] The wheel alignment detection device disclosed in this invention performs the following operations during the wheel alignment detection operation:

[0053] Drive the vehicle into the inspection station and ensure the wheel is positioned between the two wheel cleats 6. Pull the U-shaped rod 18 to release the axial lock on the wheel support rod 17. Then, rotate the first turning handle 802 to change the position of the pressure sensor carrier plate 9. This, in conjunction with the spring 11, clamps the two wheel cleats 6 on both sides of the wheel. The pressure value sensed by the pressure sensor 10 is simultaneously monitored through the data collection module 5. When the critical value is reached (i.e., the pressure value fluctuates around "0"), stop rotating the first turning handle 802, and clear the data in the data collection module 5.

[0054] Then, the second turning handle 131 is rotated to move the slider 14 laterally, and the substrate 15 drives the resistance wire type sensitive grid to move until it contacts the outer surface of the wheel.

[0055] The vehicle is then started and the wheels are allowed to idle. When the wheel deviates radially, the substrate 15 deforms and transmits data to the data collection module 5. When the wheel deviates axially, the data is transmitted to the data collection module 5 via the pressure sensor 10. Personnel only need to observe the data collection module 5 to determine whether the wheel is deviated during rotation, which serves as the basis for wheel position detection.
