Abstract

The invention relates to the technical field of vehicle axles, and discloses an installation structure of a wheel-side reducer and a wheel-side reduction axle assembly. The wheel side reducer installation structure is used to connect the planetary reducer and the axle housing, the planetary reducer is connected to one end of the half shaft, the axle housing is rotatably sleeved on the half shaft, and the axle housing is arranged on the end face of the planetary reducer. The limit boss is provided with an external thread on the outer peripheral surface of the limit boss. The installation structure of the wheel side reducer also includes a ring gear bracket and a locking nut. The ring gear bracket is used to connect with the planetary reducer, and the ring gear bracket is provided with There are installation holes, the installation holes are sleeved on the limit boss, the side of the ring gear bracket away from the planetary reducer is in contact with the end face, the lock nut is matched with the external thread, and the lock nut and the ring gear bracket are close to the side of the planetary reducer Abut. The mounting structure of the wheel-side reducer has a compact structure along the axial direction and low manufacturing cost. The wheel-side reduction axle assembly is provided with the above-mentioned wheel-side reducer installation structure, and the axial structure is compact and the space occupied is small.

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] like 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 axle...
