Embodiment 1

[0039]The differential gear includes a casing 1 , and the casing 1 includes a casing one 2 and a casing two 3 fixed by fasteners 10 . Both the first shell 2 and the second shell 3 are cylindrical with one side open, and the inner cavity of the first shell 2 and the inner cavity of the second shell 3 constitute the installation cavity 1 a of the outer shell 1 . An input gear 4 is fixedly connected to the outer side of the housing one 2, and the two are integrally constructed. Two planetary gears 5 and two side gears 6 are arranged in the installation cavity 1a, and the two planetary gears 5 are meshed with the two side gears 6 respectively. The installation cavity 1a is provided with a positioning shaft 7, and the two planetary gears 5 are respectively sleeved on two ends of the positioning shaft 7, and the side of the housing 1 is provided with a through hole 1b for the two ends of the positioning shaft 7 to pass through. Housing one 2 is provided with connection hole one 2a,...

Embodiment 2

[0047] The structure and principle of this embodiment are basically the same as those of Embodiment 1, the difference is that the shell includes shell one 2 and shell two 3 fixed by fasteners, and shell one 2 and shell two 3 are all in the same shape. The side opening is cylindrical, and the through hole 1b is set on the shell one 2 .

Embodiment 3

[0049] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that the other side of the gasket 8 is a plane, and the mating surface 9b1 is a plane.

Abstract

The invention provides a differential mechanism, and belongs to the technical field of vehicle components. The problem that an existing differential mechanism is poor in working stability is solved. The differential mechanism comprises a shell, a positioning shaft is arranged in the shell, gaskets and planetary gears are arranged at the positions, close to the two ends, of the positioning shaft ina sleeving mode, the two planetary gears are located between the two gaskets, one side faces of the gaskets are in spherical fit with the corresponding planetary gears, through holes allowing the twoends of the positioning shaft to penetrate are formed in the side portion of the shell, the two ends of the positioning shaft are sleeved with bushings correspondingly, the two bushings are arrangedat the through holes correspondingly, the two gaskets are located between the corresponding bushings and the corresponding planetary gears correspondingly, and the inner end faces of the bushings arematched faces making surface contact with the other side faces of the gaskets in an attached mode. The differential mechanism has the advantages of being high in abrasion resistance, low in productioncost, high in working stability and the like.

Description

technical field [0001] The invention belongs to the technical field of vehicle components, and relates to a differential, in particular to a differential for an electric tricycle. Background technique [0002] The differential is a very important system in an electric tricycle. When the vehicle is turning or driving on an uneven road, the two rear wheels of the electric tricycle are turned at different speeds, that is, the two wheels are guaranteed to perform pure rolling motion. It mainly includes a casing and two side gears and two planetary gears arranged inside. The two planetary gears are arranged on a shaft passing through the casing, and the two planetary gears are respectively formed with the two side gears. meshing, and an input gear is fixed outside the housing. When in use, the two rear wheels of the electric tricycle are connected to the two half-shaft gears respectively through the wheel shaft, and the input gear receives power to drive the casing to rotate, an...
