Problems solved by technology

The slender planetary gear is easy to bend during the heat treatment process, and the slender and partially intersecting holes on the planet carrier are neither convenient for machining nor surface strengthening treatment, so the manufacturing cost is high

Embodiment Construction

[0035] like Figure 1-7 As shown, the present invention is applicable to the asymmetric structure limited-slip differential between the drive wheel and the drive axle, which includes a differential case 1 and is fixed in the differential case 1 to the planetary gear 4 and 5 planetary carrier 6 which transmits the input torque and maintains its position;

[0036] A first side internal gear 2 and a second side internal gear 3, which are arranged at the first end and the second end in the differential case 1, as two power output ends of the differential;

[0037] A first-side planetary gear 4 and a second-side planetary gear 5 are provided on the planetary carrier 6 inside the differential case 1 and meshed with each other, wherein the first-side internal gear 2 is only connected to the first-side The planetary gear 4 is meshed, and the second-side internal gear 3 is only meshed with the second-side planetary gear 5;

[0038] A first inner hole 61 is formed on the planet carrie...

Abstract

A kind of limited-slip differential with an asymmetric structure comprises of a differential case (1); a planet carrier (6) fixed in it; first-side and second-side annular gears (2, 3); first-side and second-side planet gears (4, 5) situated in the planet carrier (6) and engaging with each other, the first-side annular gear (2) engaging and only engaging with first-side planet gear (4), the second-side annular gear (3) engaging and only engaging with second-side planet gear (5); a first bore (61) machined in planet carrier (6), the first-side planet gear (4) situated in the first bore (61) with sliding fit; and a second bore (62) machined in planet carrier (6), the second-side planet gear (5) situated in the second bore (62) with sliding fit. The ability in slip limitation of limited-slip differential according to present invention is proportional to input torque applied to the differential.

Description

technical field [0001] The invention relates to a limited-slip differential suitable for inter-wheel and multi-axle drive wheel vehicle drive axles, in particular to a limited-slip differential with double-sided internal meshing and asymmetric layout. Background technique [0002] In order to improve the off-road performance and passing ability of vehicles, many off-road vehicles, off-road load-bearing vehicles and engineering vehicles adopt different types of inter-wheel and / or multi-axle drive layouts. In order to distribute the power to each driving axle and adapt to the actual situation that the average rolling distance of the driving wheels on each driving axle is unequal due to unequal turning radius and uneven ground, a differential is usually used between each driving axle. Distribute torque and power. Due to the different loads on each driving axle, in order to make full use of the adhesion on each driving wheel to obtain the maximum driving force, it is required t...
