The hub reduction gear is the last stage of speed reduction and torque increase device in an automobile transmission system, is generally arranged in the middle or near a wheel hub, can reduce the load of components such as a transmission, a transmission shaft, a main speed reducer, a differential mechanism, a half shaft and the like, has the advantages of small size, larger ground clearance of a drive axle and the like under the condition of the same total transmission ratio by adopting the hub reduction gear, and is widely applied to trucks, large buses, off-road vehicles and other large industrial and mining vehicles.

The structure of the wheel-side reducer generally comprises a shell, a reduction gear and the like, and when the wheel-side reducer works, the power output by the reduction gear box of the engine drives the reduction gear to rotate through a related mechanism, and then the reduction gear drives wheels to rotate. In order to ensure the effective transmission of power and reduce the abrasion of gears, engine oil is arranged in the shell of the wheel-side speed reducer. In the actual work of the wheel reduction gear, the oil amount is reduced under the influence of various factors (including leakage and the like), so that the oil amount in the shell needs to be detected at intervals by a driver in order to reduce the influence of the too small oil amount on the work of the wheel reduction gear. At present, the structure of a wheel reduction gear is limited, a driver generally takes off a plug at the front upper end of a shell for detecting the oil amount in the shell, then an oil dipstick and the like are vertically inserted into the shell through a detection hole, and then the oil dipstick is taken out to observe an oil flooding mark of the oil dipstick, so that the actual oil amount in the shell is obtained. Because in the operation, need screw off and screw in plug, consequently can bring certain inconvenience for the driver, and owing to judge the machine oil volume through the mark of the dipstick that floods, the effect is not directly perceived, can bring the influence to the judgement of machine oil volume (for example the dipstick from top to bottom inserts and detects the trompil in-process, is stained with the machine oil easily, consequently can bring certain interference to the machine oil volume of follow-up range estimation reality). Based on the above, the wheel reduction gear which is convenient and practical and can judge the oil amount in the shell more visually is especially necessary.

Before the driver needs to detect the amount of engine oil in the casing of the hub reduction gear body 1, the wheel is required to rotate to the position where the detection hole 101 is located at the upper end in accordance with the existing detection mode. After the wheels are in place, a driver inserts two insertion tubes CZ at the lower end of the upper barrel outside two insertion rods CT in the upper end of the lower barrel, and then a power switch S can be turned on, so that the positive pole of a 6V power supply can enter one end of a reed switch GH through one insertion tube CZ and one insertion rod CT; in practical situations, when the amount of engine oil in the shell is enough, under the buoyancy action of the engine oil, the floater and the magnet CT move upwards along the guide rod through the guide hole in the middle part to approach the reed pipe GH, and the internal contact of the reed pipe GH is closed under the magnetic action force of the magnet CT; when the oil amount in the shell is insufficient, the buoyancy of the oil is reduced, the floater and the magnet CT move downwards along the guide rod through the guide hole in the middle, and the distance between the magnet CT and the reed pipe GH is enlarged, so that the reed pipe GH is not opened by the magnetic force of the magnet CT.
