Embodiment 1

[0038] A two-wheeled electric vehicle gear system composed of graphene-lubricated plastics includes a center wheel, a plurality of planetary wheels with the same specifications and respectively meshing with the center wheel, and a ring gear meshing with the planetary wheels. When in use, the center wheel is connected to the drive structure, and after the speed of the drive structure is transmitted to the ring gear through the planetary gear, the speed of the ring gear is reduced relative to the center wheel, and the center wheel, planetary gear and ring gear form a planetary gear reduction structure, which can effectively realize deceleration function.

[0039] Since the center wheel, the planetary gear and the ring gear are meshed by gears, on the one hand, in the long-term use process, it is easy to wear and cause the failure of the reduction gear; In this application, the center wheel, the planetary wheel and the ring gear are respectively an integrated body made of graphen...

Embodiment 2

[0055] This embodiment is basically the same as the above-mentioned embodiment 1, except that the components and preparation methods of the graphene nanosheet self-lubricating plastic are different, and the similarities will not be described in detail.

[0056] The graphene nanosheet self-lubricating plastic, in parts by mass, includes 13 parts of edge graphene oxide nanosheets, 85 parts of engineering plastics, 1 part of dispersant and 0.5 part of modification aid. Among them, polyamide (PA) is selected as the engineering plastic, 1 part of calcium stearate is selected as the dispersant, and quadruple bisphosphonate is selected as the modification additive.

[0057] Wherein, edge graphene oxide nanoplatelets are prepared by the following steps:

[0058] a. Using natural graphite flakes as raw materials, steel needles as grinding bodies, needle-to-material mass ratio 40:1, hydrogen peroxide as grinding media, and grinding for 8 hours at a magnetic field switching frequency of ...

Embodiment 3

[0071] This embodiment is basically the same as the above-mentioned embodiment 1, except that the components and preparation methods of the graphene nanosheet self-lubricating plastic are different, and the similarities will not be described in detail.

[0072] The graphene nanosheet self-lubricating plastic, in parts by mass, includes 16 parts of edge graphene oxide nanosheets, 95 parts of engineering plastics, 4 parts of dispersant and 2 parts of modification aid. Among them, polycarbonate (PC) is selected as the engineering plastic, bis stearic acid amide is selected as the dispersant, 1 part of polyethylene wax and 1 part of tetraerythritol ester are selected as modification additives.

[0073] Wherein, edge graphene oxide nanoplatelets are prepared by the following steps:

[0074] a. Using natural flake graphite as raw material, steel needles as grinding body, needle-to-material mass ratio 60:1, hydrogen peroxide as grinding medium, and grinding for 10 hours at a magnetic...

Abstract

The invention relates to the technical field of reduction gears for electric vehicles, in particular to a two-wheel electric vehicle gear system made of graphene-lubricated plastics. It includes a center wheel, a number of planetary gears with the same specifications and respectively meshed with the center wheel, and a ring gear meshed with the planetary wheel; the center wheel, the planetary wheel and the ring gear are graphene nanosheets One-piece molded body made of lubricated plastic. Among them, the graphene nanosheet self-lubricating plastic uses edge graphene oxide nanosheets and engineering plastics as the main raw materials, making the gear system have the characteristics of self-lubricating, high strength, strong wear resistance, silent, high temperature resistance, no deformation, and light weight , and low cost, wide application range, strong practicability.

Description

technical field [0001] The invention relates to the technical field of reduction gears for electric vehicles, in particular to a two-wheel electric vehicle gear system made of graphene-lubricated plastics. Background technique [0002] With the increasingly serious environmental pollution, people's awareness of environmental protection is constantly improving, low-carbon and green have gradually become the mainstream of life, and two-wheeled electric vehicles have become an important travel tool for people because of their lightness and labor-saving. A car driven by electricity and powered by electricity. One of the most important systems in two-wheeled electric vehicles is the speed control system. With the popularity of two-wheeled electric vehicles, the speed control system has also been greatly developed. [0003] Among them, the reducer is an important transmission device in the speed control system, which is mainly used to reduce the speed and increase the torque to m...
