Abstract

The invention belongs to the technical field of differential mechanisms, particularly relates to a low noise differential mechanism. The low noise differential mechanism comprises a left lubrication cavity, a right lubrication cavity and a lower lubrication cavity. The left and right lubrication cavities are relatively arranged and are correspondingly arranged on the lateral sides of a second though hole. The lower lubrication cavity is located between the left and right lubrication cavities. One end of the lower lubrication cavity communicates with the left and right lubrication cavities at the same time. A pushing plate is transversely arranged at the other end of the lower lubrication cavity. The pushing plate is connected with a linear motor. The pushing plate vertically reciprocates in the lower lubrication cavity. Lubrication packs communicating with the corresponding cavities are correspondingly arranged at the ends of the left and right lubrication cavities. Flexible pipes arearranged at the tops of the lubrication packs. The flexible pipes extend to the positions above planetary gears. Oil outlets are formed in the free ends of the flexible pipes. The lubrication structure in an existing differential mechanism is completely changed by the low noise differential mechanism, the problem of incomplete lubrication of the connecting positions of the planetary gears can be solves, and loud noise can be avoided.

Description

technical field [0001] The invention belongs to the field of differentials, in particular to a low-noise differential. Background technique [0002] A differential is a differential mechanism that transmits rotational motion from one shaft to two shafts and enables the latter to rotate at different speeds relative to each other. The automobile differential is the main part of the drive axle. Its function is to allow the two axle shafts to rotate at different speeds while transmitting power to the axle shafts on both sides, so that the wheels on both sides can run at unequal distances in the form of pure rolling as much as possible. Reduce the friction between the tire and the ground. [0003] The various gears inside the existing differential are meshed with each other, including the meshing of the main drive gear and the meshing of planetary gears. The structure is too complicated, and each gear meshing requires a certain amount of lubricating oil. Due to the excessive nu...
