Novel speed reducing structure and drive axle wheel edge assembly applying same

The utility model discloses a novel speed reduction structure and a drive axle wheel edge assembly using the same, the novel speed reduction structure is arranged in the drive axle wheel edge assembly, and comprises a sun wheel, a planet wheel, a planet wheel shaft and an inner gear ring which are arranged in sequence; wherein the inner gear ring is fixed on the drive axle wheel edge assembly shell, the sun wheel is a straight bevel gear, the sun wheel is in transmission connection with the planet wheel and is connected with the input shaft through a bearing, and the planet wheel shaft is sleeved in a shaft hole of the planet wheel. The planetary reduction system has the advantages that the teeth of the bevel gear have taper angles and incline by a certain angle, so that when the sun gear,the planet gears and the inner gear ring are sequentially arranged in the radial direction, the radial size of the planetary reduction system is reduced, the structure is compact, and light weight and small tire arrangement
