Abstract

The invention provides a three-fork-shaft-type noncircular bevel gear limited slip differential which is simple in structure, low in cost and high in strength. The three-fork-shaft-type noncircular bevel gear limited slip differential is provided with a differential shell, a left noncircular bevel half shaft gear, a right noncircular bevel half shaft gear and three noncircular bevel planetary gears. The left noncircular bevel half shaft gear is installed in a left half shell of the differential shell. The right noncircular bevel half shaft gear is installed in a right half shell of the differential shell. The three noncircular bevel planetary gears are installed in the differential shell through a three-fork shaft. The three-fork shaft is in a Y shape with three branch shafts. The three branch shafts are evenly distributed at equal angles. The three noncircular bevel planetary gears are meshed with the left noncircular bevel half shaft gear and the right noncircular bevel half shaft gear. The number of teeth of the noncircular bevel planetary gears, the number of teeth of the left noncircular bevel half shaft gear and the number of teeth of the right noncircular bevel half shaft gear are the same.

Description

technical field [0001] The invention relates to a limited-slip differential, in particular to a trident shaft-type non-conical gear limited-slip differential. Background technique [0002] At present, cars are gradually becoming a common means of transportation, and self-driving tours are increasingly becoming the way of travel that people pursue, but ordinary cars are difficult to drive in mountainous areas and other areas, so off-road vehicles have become the first choice for some people. [0003] Since off-road vehicles often drive on muddy, soft roads or even roadless areas, passability is one of its most important performance indicators. As an important part of the car, the differential is to distribute the torque between the two output shafts and ensure that the two output shafts may rotate at different angular velocities. Its form and performance are directly related to the passability of the vehicle. [0004] At present, my country's off-road vehicle drive axles gen...
