The driving wheel unit 160 is rotatably set in the driving wheel seat 140 to test the wear resistance of the supporting wheel body 20 by rotation. There are two driving wheel units 160 corresponding to the number of the supporting wheel bodies 20, and each of the supporting wheel bodies 20 is correspondingly abutted with one driving wheel unit 160; the driving assembly 150 is used to drive the driving wheel unit 160 to rotate, and the driving wheel unit 160 rotates to cooperate in testing the wear resistance and rotatability of the supporting wheel body 20.

[0040] It should be noted that the H-shape can support the supporting roller body 20 installed on the mounting base 122 to a certain height to ensure that there is a gap between the supporting roller body 20 and the bottom of the water tank 120 so that it can rotate. At the same time, the H-shape has two top ends, which can allow the two supporting roller bodies 20 to be installed on the top ends of the mounting base 122 respectively, and the two ends are also arranged at a distance, and the two supporting roller bodies 20 can be arranged at a better distance to avoid affecting each other's rotation; it can be understood that the through holes at the top ends of the mounting base 122 are used for the rotating shaft 220 of the supporting roller body 20 to pass through and install, so that it can be rotatably connected to the mounting base 122.

[0041] As a preferred embodiment of the present invention, each of the supporting wheel bodies 20 includes a rotating shaft 220 and two supporting wheels 210 arranged opposite to each other in the longitudinal direction. The rotating shaft 220 passes through the through hole and is rotatably arranged. Both ends of the rotating shaft 220 extend out of the through hole, and the two supporting wheels 210 are respectively connected to the two ends of the rotating shaft 220.

[0042] It should be noted that each of the supporting wheel bodies 20 adopts the form of one shaft and two wheels, so that when serving as the supporting wheel 210 part of the track wheel, it has a larger contact area with the ground, reduces pressure and resistance, and improves stability; during testing, the rotating shaft 220 is passed through the through hole and the two ends are extended out, and then the two supporting wheels 210 are respectively installed at the two ends of the rotating shaft 220.

[0043] As a preferred embodiment of the present invention, each of the supporting wheels 210 includes a wheel body 211 and an oil seal 212, a first deep groove ball bearing 213, a spacer sleeve 214, a second deep groove ball bearing 215, a gasket 216 and an end cover 217 arranged in sequence from the inside to the outside along the axial direction of the rotating shaft 220.

[0044] It is worth mentioning that the wheel body 211 is the supporting wheel 210 itself, and various components are installed between the wheel body 211 and the rotating shaft 220 to ensure the performance of the supporting wheel 210, wherein the oil seal 212 is used to protect the internal lubricating oil from leaking out, and at the same time to prevent external mud, water, dust, etc. from entering the interior to cause damage to the components. The first deep groove ball bearing 213 and the second deep groove ball bearing 215 are both used to bear the load and can also reduce the deviation of the rotating shaft 220.

[0045] As a preferred embodiment of the present invention, each of the driving wheel units 160 includes a driving shaft 161, a driving wheel 162, a transmission wheel 163 and two bearings 164 arranged opposite to each other in the transverse direction.

[0047] Furthermore, each of the driving wheel units 160 further includes a wheel sleeve 165 , and the wheel sleeve 165 is sleeved on the driving wheel 162 and is disposed against the supporting wheel body 20 .

[0048] It should be noted that the wheel sleeve 165 facilitates the abutting connection between the driving wheel 162 and the supporting wheel body 20 to increase contact friction, and it can take the form of a track to further simulate the environment in which the supporting wheel body 20 is installed in the track.

[0049] Furthermore, the frame 110 includes a base plate 111 and four guide rods 112 distributed in a matrix around the base plate 111, the guide rods 112 extend vertically, the bottom ends of the guide rods 112 are connected to the base plate 111, the driving wheel seat 140 is connected to the top ends of the guide rods 112, and the water tank 120 is connected to the middle of the guide rods 112 and is movably arranged vertically.
