[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-4 The utility model provides a technical solution: a rear axle assembly gauge, comprising a gauge housing 1, the gauge housing 1 is an annular structure, the interior of the gauge housing 1 is evenly distributed with a plurality of connecting plates 51 in a circumferential manner, the shape of the adjacent side of the connecting plate 51 to the gauge housing 1 is adapted to the shape of the inner wall of the gauge housing 1, when in use, the rear axle assembly is extended into the interior of the gauge housing 1, and the detection components are evenly installed inside through the connecting plate 51, so as to facilitate detection within a circumferential surface;
[0020] One side of the connecting plate 51 is connected with a sliding column 5 by welding. The sliding column 5 is made of non-conductive material. The outer walls of both sides of the sliding column 5 are fixedly connected with conductive copper sheets 3 by welding. When the rear axle assembly is rotated during use, the conductive copper sheets 3 are connected electrically by a medium, forming an effect similar to a sliding rheostat.
[0021] A square block 7 is slidably mounted on the outer wall of the sliding column 5. One end of the sliding column 5 passes through the outer wall of the square block 7. A conductive ring 6 is fixedly connected to one side of the square block 7 by welding. The inner wall of the conductive ring 6 is in sliding contact with the conductive copper sheet 3 and is mutually conductive. A magnetic block 2 is connected to one side of the square block 7, and the activity of the magnetic block 2 is observed. The magnetic block 2 moves when attracted by magnetic forces of different strengths. The movement drives the square block 7 to move, and causes the conductive ring 6 to move, forming different conduction resistances. When the resistance is large, it means that the magnetism of the rear axle assembly is strong, and when the resistance is small, it means that the magnetism of the rear axle assembly is weak. Observe whether each magnetic block 2 deviates beyond the normal value when the rear axle assembly rotates;
[0022] A spring 4 is connected to one side of the connecting plate 51, and one end of the spring 4 contacts one side of the square block 7. The spring 4 is used to reset each square block 7 for the next detection.
[0023] The two conductive copper sheets 3 on the same sliding column 5 are electrically connected to each other through a wire, and one end of the conductive copper sheet 3 is electrically connected to a power supply 8 and a current sensor 81. The power supply 8 provides power for the connection between the two conductive copper sheets 3, and the current sensor 81 facilitates intuitive display of the current.
[0024] The model of the current sensor 81 is LSC-1X-10A, and this type of current sensor is convenient for detecting slight changes in small currents.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
