Problems solved by technology

[0002] At present, the existing electric vehicles use one or more motors and are equipped with mechanical transmissions. It is difficult for electric vehicles to start, go uphill, and accelerate; if the starting power is large enough, the mileage will be shortened and the power consumption will be high. A lot of inconvenience, so the popularization and application of electric vehicles is greatly restricted

Embodiment

[0020] like figure 1 , is an embodiment of the driving structure of the environment-friendly electric vehicle, the front axle 3 of the electric vehicle is provided with a hub motor 1; the series motor 5 is connected to the rear axle 6 through mechanical reduction devices 10, 11, 9, 8; A clutch 11 is provided between the excitation motor 5 and the in-wheel motor 1 . The speed governors 12, 14, 15 have a speed regulating mechanism controlled synchronously by one foot or one hand or both hands and feet. Clutch 11 is an overrunning clutch. The storage battery 4 is a lithium battery, a lead-acid battery, a zinc-air battery or a combination of an ordinary battery and a capacitive battery. The in-wheel motor 1 is installed at the wheel position of the front axle 3, and the series-excited motor 5 is connected with the rear axle 7 through a mechanical deceleration device and a clutch 11. The electric vehicle has two wheels in the front and one wheel in the back. The front axle has t...

Abstract

The invention belongs to the technical field of electric vehicles and especially relates to an environmentally friendly electric vehicle drive structure. Wheel-hub motors are installed on a front vehicle shaft or a plurality of vehicle shafts of the electric vehicle; a series machine is connected with another vehicle shaft through a mechanical reduction gear; a control circuit structure is configured as follow: the series machine and the wheel-hub motors are respectively connected with speed controllers in a series mode, then the series machine and the wheel-hub motors are connected in a parallel mode and finally connected with a battery in a series mode to form a circuit with switches; a clutch is installed between the series machine and the wheel-hub motors. The invention solves the contradiction between the limited energy of the electric vehicle in the prior art and the large demand for power when starting, going uphill and accelerating; at the same time, the efficiency is increased, the self-weight of the vehicle is reduced, the cost is reduced and fault rate is reduced; the structure has the advantages of saving power, starting fast and increasing mileage, which can be widely used in six-wheeler, four-wheeler, three-wheeler and two-wheeler electric vehicles.

Description

technical field [0001] The patent of the invention belongs to the technical field of electric vehicles, and in particular relates to an environment-friendly electric vehicle driving structure. Background technique [0002] At present, the existing electric vehicles use one or more motors and are equipped with mechanical transmissions. It is difficult for electric vehicles to start, go uphill, and accelerate; if the starting power is large enough, the mileage will be shortened and the power consumption will be high. A lot of inconvenience, so the popularization and application of electric vehicles is greatly restricted. Contents of the invention [0003] The purpose of the patent of the present invention is to provide an environment-friendly electric vehicle drive structure, thereby solving the contradiction between the limited energy of the electric vehicle in the prior art and the large power demand for starting, accelerating, and uphill, and has the advantages of power s...
