Abstract

The invention provides a differential planetary gear structure which comprises a driven gear, a planetary gear carrier, planetary gears, a left half axle gear, a right half axle gear, a left half axle and a right half axle, wherein the left half axle gear is arranged on the left half axle, the right half axle gear is arranged on the right half axle, the left half axle gear and the right half axle gear are meshed with the planetary gears respectively, each planetary gear comprises an axle and a gear fixed at one end of the axle, the axle is rotationally arranged on the planetary gear carrier, the planetary gear carrier is arranged on the driven gear and rotates with the driven gear synchronously, and the driven gear is rotationally arranged on the left half axle or the right half axle in a sleeving manner. The invention further relates to a vehicle. The differential planetary gear structure and the vehicle are simple and compact in structure, omit a straight axle or a cross axle between the two planetary gears compared with a traditional differential, reduce the processing difficulty and the processing and manufacturing costs, are simpler to assemble and have good extendability and universality.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a differential planetary gear structure and a vehicle. Background technique [0002] The differential is an important part of the vehicle. It allows the vehicle to rotate at different speeds when the vehicle is turning or driving on an uneven road, so that the wheels on both sides can be driven at unequal distances in the form of pure rolling as much as possible, reducing tire contact with the vehicle. Ground friction. At present, the planetary gear structure of the differential is generally in the form of a cross shaft or a solid shaft structure, so that the two planetary gears are connected together. As a result, the assembly manufacturability is not very ideal, the assembly is difficult, and it is very inconvenient for future maintenance, and the precision required by the cross shaft or the straight shaft and the manufacturing and processing costs are relativel...
