Automobile differential with any tooth difference between outer cam and shock-wave rolling block

Abstract

An automobile differential with any tooth difference between an outer cam and a shock-wave rolling block belongs to the technical field of mechanical transmission. The invention provides a novel automobile differential; a bevel gear is arranged outside an outer-tooth internal retainer of the novel automobile differential, while a sleeve structure is formed inside the outer-tooth internal retainer; a rolling block is in multi-teeth engagement with all of the outer-tooth internal retainer, a left half axle multi-phase outer cam and a right half axle internal gear. Power is input by the bevel gear outside the outer-tooth internal retainer and transmitted to the rolling block through the sleeve structure of the outer-tooth internal retainer, and then the rolling block transmits the power to the left half axle multi-phase outer cam fixedly connected with left wheels and the right half axle internal gear fixedly connected with right wheels, and therefore, differential speeds between the left and right wheels are realized. The differential has no planetary gear system in a traditional automobile differential, and as the rolling block of the differential is in rolling contact connection with the outer-tooth internal retainer, the differential has the advantages of compact structure, small volume, multi-tooth engagement, large contact ratio, high carrying capacity and high transmission efficiency and thus can be widely applied to various wheeled vehicles needing the differential, such as automobiles, engineering vehicles and so on.

Description

technical field [0001] The invention relates to an automobile differential with arbitrary tooth difference external cam shock wave rolling block, which is used for the differential speed of wheeled vehicles and belongs to the technical field of mechanical transmission. Background technique [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 coincides The degree is low, so the carrying capacity is low and the transmission effici...
