Abstract

The invention belongs to the technical field of automobiles. The invention discloses a wheel reductor structure. The structure comprises a sun gear, a plurality of planet gears, a half shaft, an end cover, a wheel reductor shell, a hub, a planet carrier and a gear ring, and also comprises a shaft sleeve and a bracket fixed to the planet carrier, wherein the half shaft penetrates through the shaftsleeve from the middle part and can freely rotate in the shaft sleeve; the bracket is fixed on the shaft sleeve; the sun gear is fixed on the half shaft to be used as power input; and the gear ring isfixed on the wheel reductor shell to be used as power output. The wheel reductor structure has the beneficial effects that the planet carrier is fixed, the sun gear is adopted as power input, and thegear ring is adopted as power output, so that the reduction ratio is reduced, the transmission efficiency is improved, and market requirements are better met; meanwhile, the gear ring is integrated on the wheel reductor shell so that the weight of the wheel reductor is reduced than that in an existing structure that the gear ring and the wheel reductor shell are arranged separately.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a wheel-side reducer structure. Background technique [0002] The wheel reducer is one of the components of the automobile axle, which can reduce the speed transmitted from the main reducer and increase the torque of the gear end. In the domestic wheel reducer, the sun gear is generally used as the power input, and the planetary gear is used as the power output. The common structures are as follows: [0003] Patent Document 1 (CN202992122U) discloses a heavy-duty vehicle axle wheel reducer structure, including sun gear, sun wheel outer washer, half shaft, end cover, wheel reducer housing, multiple planetary wheels, collar and A plurality of planetary wheel washers, the inner diameter of the outer washer of the sun wheel is larger than the outer diameter of the sun wheel, a retaining ring is arranged between the sun wheel and the collar, and an axial limit device of the half ...
