Outer cam shock wave-type pure rolling automobile differential mechanism with arbitrary tooth difference

Abstract

The invention discloses an outer cam shock wave-type pure rolling automobile differential mechanism with an arbitrary tooth difference and belongs to the technical field of mechanical transmission. The invention provides a novel automobile differential. A bevel gear is arranged at the outer part of an outer tooth inner retainer; the inner part of the outer tooth inner retainer has a sleeve structure; a movable sleeve roller is in multi-tooth meshing with the outer tooth inner retainer, and a left half shaft multiphase outer cam and a right half shaft inner gear are in multi-tooth meshing; and all meshing parts are in pure rolling contact. According to the outer cam shock wave-type pure rolling automobile differential mechanism provided by the invention, the power is input by the bevel gear arranged at the outer part of the outer tooth inner retainer, transferred to the movable sleeve roller through the outer tooth inner retainer and then transferred to the left half shaft multiphase outer cam which is fixedly connected with a left automobile wheel and the right half shaft inner gear which is fixedly connected with a right automobile wheel through the movable sleeve roller, so that a differential velocity between the left automobile wheel and the right automobile wheel is realized. The outer cam shock wave-type pure rolling automobile differential mechanism eliminates a planetary gear system in the traditional automobile differential mechanism, has compact structure, small size, light weight, large coincidence degree, high carrying capacity and high transmission efficiency, is in multi-tooth meshing and can be widely used in various wheeled vehicles needing differential mechanisms, such as automobiles, construction vehicles and the like.

[0002] At present, the commonly used automotive differentials use a planetary gear system composed of multiple straight-toothed bevel gears to achieve the purpose of differential speed. Although this system can realize the differential speed of the left and right axle shafts of the car, there are many components in the system. , the axial and radial dimensions are large, the volume is large, and the weight is heavy, especially for heavy-duty vehicles, in order to achieve differential speed and transmit sufficient power, the volume and weight will be further increased; straight bevel gear transmission is also It has the disadvantages of low coincidence, low load capacity, low transmission efficiency, difficult processing of straight bevel gears, and poor manufacturability.
