Problems solved by technology

In the traditional helical helical gear limited-slip differential, the two planetary gears in each set of planetary gear sets mesh with each other through their respective meshing areas in the middle. This structure makes the axis of the planetary gears easily Deviations occur, causing the axis of the planetary gear to be non-paral

Abstract

The invention discloses a cylinder helical tooth stress balanced limited-slip differential. Each planetary gear comprises a long meshing gear part, a short meshing gear part and an optical axis, wherein the part, far away from the optical axis, of the long meshing gear part of one planetary gear in the same planetary gear set is located outside a first sun gear meshing region, and the short meshing gear part is located outside a second sun gear meshing region; the part, far away from the optical axis, of the long meshing gear part of the other planetary gear in the same planetary gear set is located outside the second sun gear meshing region, and the short meshing gear part is located outside the first sun gear meshing region; and the short meshing gear part of one planetary gear in the same planetary gear set is meshed together with the part, far away from the optical axis, of the long meshing gear part of the other planetary gear. Due to the adoption of such a meshing way in the cylinder helical tooth stress balanced limited-slip differential, the axis of each planetary gear is parallel to the axis of an axle hole of a differential case as much as possible, so that the aims of increasing the gear meshing contact area, reducing stress unbalance of a small gear surface and prolonging the life of the differential are achieved.

Description

technical field [0001] The invention relates to a limited-slip differential, in particular to a cylindrical helical tooth stress-balanced limited-slip differential. Background technique [0002] When the car is turning, the limited-slip differential is the same as the ordinary differential, so that the left and right driving wheels output different speeds. , The planetary gears in the limited-slip differential apply force outward during the meshing process, forming friction with the differential case, and the friction generates a differential limiting force, thereby playing the role of limited slip. In the traditional helical helical gear limited-slip differential, the two planetary gears in each set of planetary gear sets mesh with each other through their respective meshing areas in the middle. This structure makes the axis of the planetary gears easily Deviations occur, causing the axis of the planetary gear to be non-parallel to the axis of the shaft hole of the differe...
