Abstract

The invention relates to the technical field of axles, and discloses a hub reduction gear mounting structure and a hub reduction axle assembly. The hub reduction gear mounting structure is used for connecting a planetary reduction gear and an axle housing, the planetary reduction gear is connected to one end of a half shaft, the axle housing is rotatably arranged on the half shaft in a sleeving mode, a limiting boss is arranged on the end face, close to the planetary reduction gear, of the axle housing, and external threads are arranged on the outer circumferential face of the limiting boss. The hub reduction gear installation structure further comprises a gear ring support and a locking nut, the gear ring support is used for being connected with the planetary reduction gear, a mounting hole is formed in the gear ring support, the limiting boss is sleeved with the mounting hole, the side face, away from the planetary reduction gear, of the gear ring support abuts against the end face, and the locking nut is in threaded fit with the external thread. The locking nut abuts against the side face, close to the planetary reducer, of the gear ring support. The hub reduction gear mounting structure is compact in structure in the axial direction and low in manufacturing cost. The hub reduction axle assembly is compact in axial structure and small in occupied space by arranging the hub reduction gear mounting structure.

Description

technical field [0001] The invention relates to the technical field of vehicle axles, in particular to a mounting structure for a wheel-side reducer and a wheel-side reduction bridge assembly. Background technique [0002] The wheel reducer is the last stage reduction device in the automobile transmission system. Its function is to reduce the speed and torque transmitted by the main reducer and increase the torque, and then transmit it to the wheel hub, so that the wheel will produce a higher torque under the reaction of the ground adhesion. Large driving force, wheel reducers are widely used in trucks, large buses, off-road vehicles and some other large industrial and mining vehicles. [0003] Such as figure 1 As shown, the wheel reduction axle assembly includes a half shaft 1', an axle housing 2' sleeved on the half shaft 1', a hub connected to the axle housing 2' and a planetary reducer 3', and the planetary reducer 3' is connected to Between the half shaft 1' and the a...
