Differential mechanism and differential mechanism shell thereof

Abstract

The invention relates to a differential mechanism and a differential mechanism shell thereof. The side wall of the differential mechanism shell is provided with half shaft installing through holes used for installing half shafts and a planet gear installing through hole used for installing a planet gear shaft; the differential mechanism shell is further provided with a lubricating pathway; the lubricating pathway comprises half shaft lubricating units and a planet gear lubricating unit; each half shaft lubricating unit comprises an oil guiding groove and a lubricating ring communicating with the oil guiding groove; the oil guiding grooves are formed in the hole walls of the half shaft installing through holes and spirally extend in the axial direction of the half shaft installing through holes; the lubricating rings are arranged on the portions, used for installing half shaft gear gaskets, of the inner wall of the shell in the circumferential direction of half shaft installing throughholes; the planet gear lubricating unit comprises an oil storing groove communicating with the lubricating rings and lubricating flow channels of which the two ends communicate with the oil storing groove and the planet gear installing through hole separately; the oil storing groove extends in the circumferential direction of the planet gear installing through hole; and the lubricating flow channels are arranged on the portions, used for installing planet gear gaskets, of the inner wall of the shell. Therefore, through arrangement of the lubricating pathway, the reliability of the differentialmechanism is greatly improved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a differential gear and a differential gear housing thereof. Background technique [0002] With the rapid development of the automobile industry, people have higher requirements for various performances of automobiles, such as the driving performance of automobiles at high speeds. In the gearbox differential, in order to prevent the axial movement of the planetary gears and the side gears when they rotate and to facilitate the dissipation of heat generated by the planetary gears and the side gears, the differential housing and the planetary gears and the differential A gasket is arranged between the side gear and the side gear. [0003] However, under high speed and high torque working conditions, the planetary gears and side gears will generate a large axial pressure. Under the action of this pressure, the balance between the planetary gears, side gears and the diff...
