[0032] Reference Figure 1 and Figure 3 The rotating mechanism 3 includes a rotating rod 301 and a motor 302. The rotating rod 301 is rotatably set on the side plate 2 located on the right side. The end of the rotating rod 301 away from the side plate 2 is connected to the wheel hub 4. The motor 302 is set on the side plate 2 located on the right side. The output shaft of the motor 302 is connected to one end of the rotating rod 301, which is used to drive the rotating rod 301 to rotate. The motor 302 is a variable speed motor; the testing mechanism 5 includes an electric push rod 501 and a brake body 502. The electric push rod 501 is set on the side plate 2 located on the left side. The brake body 502 is set at one end of the electric push rod 501 away from the side plate 2, and cooperates with the wheel hub 4 to perform a braking test.

[0033] By adopting the above technical solution, the electric push rod 501 drives the brake body 502 to move to the inner side of the wheel hub 4, and then the motor 302 drives the rotating rod 301 to rotate, and the rotating rod 301 rotates to drive the wheel hub 4 to rotate, so that the braking test can be performed.

[0034] Reference Figure 2 The protection mechanism 6 includes a protection cover 601, a sealing cover 602 and a transparent glass plate 603. The protection cover 601 is arranged at the upper end of the workbench 1. The sealing cover 602 is rotatably arranged at the upper end of the protection cover 601, and cooperates with the protection cover 601 to provide safety protection during the brake test. A wire entry hole is opened on the rear side of the sealing cover 602 to facilitate the connection of the brake body 502 to the external hydraulic control system. The transparent glass plate 603 is arranged on the sealing cover 602 to facilitate the staff to check the test situation.

[0035] By adopting the above technical solution, during the test process, safety protection can be provided by the protective cover 601 and the sealing cover 602 , and the transparent glass plate 603 can facilitate the staff to check the test situation.

[0036] Reference Figure 1 , Figure 2 and Figure 3 A plurality of magnets 7 are disposed on one side of the protective cover 601 and the sealing cover 602, and the corresponding two magnets 7 are magnetically attracted.

[0037] By adopting the above technical solution, during the test, the two corresponding magnets 7 are used for magnetic adsorption, so that the sealing cover 602 can fit tightly with the protective cover 601 when it is closed.

[0038] Reference Figure 2 and Figure 3 The inner sides of the protective cover 601 and the sealing cover 602 are both provided with sound insulation cotton 8.

[0039] By adopting the above technical solution, the propagation of noise during testing can be greatly reduced through the sound insulation cotton 8, making it less likely to affect the test environment.

[0040] Working principle: When the utility model is in use, the electrical components appearing in the present application are all externally connected to the power supply and the control switch. When testing, the brake body 502 is connected to the external hydraulic control system, and then the electric push rod 501 works to drive the brake body 502 to move it to the inner side of the wheel hub 4 for testing, which is simple and convenient. Then the motor 302 works to drive the rotating rod 301 to rotate, and the rotation of the rotating rod 301 drives the wheel hub 4 to rotate. The external hydraulic control system is controlled to make the brake body 502 perform friction braking on the rotating wheel hub 4. At this time, the braking situation can be observed through the transparent glass plate 603, so as to analyze the condition of the wheel hub 4. In addition, during the test, safety protection can be provided by the protective cover 601 and the sealing cover 602. At the same time, the use of sound insulation cotton 8 can greatly reduce the propagation of noise during the test, making it difficult to affect the test environment, thereby greatly improving the practicality of the device.

[0041] When the utility model is in use, the brake body 502 can be quickly moved to a position for testing the wheel hub 4, which saves time, improves the safety during the test, reduces the spread of noise, and greatly improves the practicality of the device.
