Embodiment Construction

[0026] pass below Figure 1 ~ Figure 4 As well as listing some optional embodiments of the present invention, the technical solutions (including preferred technical solutions) of the present invention are further described in detail. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] Such as Figure 1 to Figure 4 As shown, the helical angle gear type limited-slip differential designed in the present invention includes a housing 1 and two side gears 2 respectively located at both ends of the housing, and each side gear 2 is provided with a plurality of planetary gears meshing with it 3. The two side gears 2 placed in the side shaft mounting hole 1.1 of the casing 1 are coaxial and rotate in opposite dir...

Abstract

The invention discloses a large-helix-angle gear type limited slip differential. The large-helix-angle gear type limited slip differential comprises a shell and two half axle gears located at the two ends of the shell correspondingly, and each half axle gear is provided with a plurality of planetary gears meshed with the half axle gear; the two half axle gears arranged in half axle mounting holes of the shell are coaxial and are opposite in rotation direction; the planetary gears on the same side are evenly distributed in planetary mounting holes in the shell, and the axes of the planetary gears in different rotation directions are adjacent; and the two half axle gears and the plurality of planetary gears are mounted in the shell through end covers. The locking coefficient of the differential is 0.6, the torque ratio is 3.5, the problem that an existing helix tooth limited slip differential cannot adapt to medium-heavy cross-country vehicles is solved, meanwhile, the differential is light in weight, parts are easy to machine, and the low-cost and light-weight design of the differential is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile transmission parts assembly, in particular to a differential, in particular to a large helix angle gear type limited-slip differential. Background technique [0002] At present, the existing helical gear limited-slip differential has a small locking coefficient, low limited-slip capability, and poor off-road performance. It is only suitable for assembly on light-duty vehicles, while the mechanical lock type helical limited-slip differential has many parts. , complex process, high production and maintenance costs. Contents of the invention [0003] In view of the problems existing in the background technology, the object of the present invention is to provide a helical angle gear type limited-slip differential with strong limited-slip capability and improved off-road performance of the vehicle. [0004] In order to achieve the above object, the helical angle gear type limited-slip differentia...
