Full-face gear axle

Abstract

The invention relates to an automobile axle assembly, in particular to a full-face gear drive axle assembly. According to the technical scheme, the full-face gear drive axle assembly comprises a driving gear shaft, an output shaft, a differential housing, a planetary shaft, a planetary shaft sleeve, a planetary gear, a half-axle face gear and a half-axle. The half-axle face gear is installed in two transverse through holes in the inner cavity of the differential housing, and the planetary gear is installed in two longitudinal through holes in the inner cavity of the differential housing. A shoulder is arranged on the outer wall of the differential housing, a plane boss is arranged at the inner end of a planetary shaft hole, a driven face gear is installed on the shoulder through bolts anda washer, the planetary gear is limited by the planetary shaft sleeve and the plane boss in the differential housing separately, and the driving gear shaft meshes with the driven face gear to drive the differential housing to rotate. By adopting the technical scheme, the full-face gear drive axle assembly is a novel face gear drive axle main reducer assembly which is high in strength, large in drive ratio, compact in structure, low in machining cost, high in interchangeability and easy to install and maintain.

Description

technical field [0001] The invention relates to an axle assembly installed in a vehicle drive system, in particular to a comprehensive gear axle assembly in which the gear pairs of the final reducer and the inter-axle differential are both face gear pairs. Background technique: [0002] The main reducer and differential are important transmission parts of the automobile drive train. The function of the reducer is to increase the torque output by the engine and reduce the speed to match the actual vehicle transmission requirements. The function of the differential is to transmit torque to the left and right wheels while the car is running, and at the same time make the left and right wheels do pure rolling at different angular velocities, reduce the wear of the wheels, and reduce the energy consumption of the vehicle. [0003] The traditional axle main reducer realizes deceleration, torque increase, and change of torque direction through spiral bevel gear transmission. The s...

Problems solved by technology

The differentials are all driven by bevel gears, which are not interchangeable, and the manufacturing cost is higher than that of face gears

Secondly, because the bevel gear installation process must ensure that the planetary gears are aligned to the center, it is necessary to process the back of the planetary gears and the inner surface of the differential case into a spherical surface to ensure the correct meshing of the planetary gears and the side gears, which increases the process cost and installation difficulty.
