Inner double-phase, shock-wave and rolling-block type differential of automobile

Abstract

The invention provides an inner double-phase, shock-wave and rolling-block type differential of an automobile, and belongs to the technical field of mechanical transmission. The differential is a novel differnetail of the automobile and is characterized in that a bevel gear is arranged at the outer part of an outer tooth inner retainer, and a sleeve structure is arranged in the outer tooth inner retainer. The power is input through the bevel gear at the outer part of the outer tooth inner retainer and then transmitted to a rolling block through the sleeve structure in the outer tooth inner retainer; the rolling block can transmit the power to a left semi-axis center wheel which is fixedly connected to each left wheel, and a right semi-axis double-phase inner cam which is fixedly connected to each right wheel, so as to achieve differential speed of the left wheels and the right wheels. The differential is free of a planetary gear system of a traditional automobile differential, and the rolling block is in pure rolling frictional connection and multi-tooth meshing with the outer tooth inner retainer, the left semi-axis center wheel and the right semi-axis double-phase inner cam, so that the differential is compact in structure, small in size, light in weight, high in overlapping degree, high in bearing capacity, and high in transmission efficiency, performs multi-tooth meshing, and can be widely applied to various wheeled vehicles requiring the differentials, such as an automobile and an engineering vehicle.
