Abstract

The utility model relates to a hybrid single driving system of electric automobile, comprising a power supply, a controller and a motor; the motor comprises the first and second motors with same work voltage and different output powers; and the first and second motors are electrically connected with the controller via a switching control mechanism. The utility model leads the electric automobile to have good cruising ability and good power performance on the basis of not increasing vehicle-mounted accumulator, so that the practical value of the electric automobile is improved, the sales market of the electric automobile is enlarged; and the utility model provides powerful technical support for popularization and development of the electric automobile.

Description

The double dynamical single-drive system of electronlmobil

Technical field

The utility model relates to a kind of drive system of electronlmobil, the double dynamical single-drive system of specifically a kind of electronlmobil.

Background technology

Traditional electric automobile have once charging continuation of the journey mileage short with tractive performance is poor, starting is climbed shortcoming such as unable.In order to improve the flying power of electronlmobil, solution is increase or increases vehicular power-bottle, strengthens but the result who does like this is cost up, deadweight.In order to increase the tractive performance of drive system of electric automobile, solution is the horsepower output that increases motor, the result who does like this, though tractive performance strengthens, the corresponding increasing of consumption of current causes flying power to shorten.These problems perplex always and the development that restricting electronlmobil with popularize.

The utility model content

The purpose of the utility model just provides the double dynamical single-drive system of a kind of electronlmobil, to overcome the deficiency that existing drive system of electric automobile exists, improves the practical value of electronlmobil, promotes the development of electronlmobil.

The utility model is achieved in that the double dynamical single-drive system of a kind of electronlmobil; Comprise power supply, controller and motor; Said motor comprises that operating voltage is identical and first motor and second motor that horsepower output is different, and said first motor and said second motor are electrically connected with said controller through conversion and control mechanism.

The horsepower output of said second motor is than the horsepower output big 30-80% of said first motor.

The design philosophy of the utility model; In drive system, install double-motor exactly additional; And the conversion and control mechanism that passes through handled easily; Realize single motor-driven of each period---promptly under the cruising state, use the first less motor-driven vehicle of horsepower output to move ahead, come the flying power of support vehicles with less power consumption; In vehicle start or climbing; Through controlling conversion and control mechanism, drive motor is changed, use the second bigger motor of horsepower output to drive; Thereby come the tractive performance of support vehicles with bigger horsepower output, thereby make vehicle be able to successfully start to walk or climb.So just can on the basis that does not increase vehicular power-bottle, make electronlmobil both have good flying power, have good tractive performance again concurrently.

The utility model has improved the practical value of electronlmobil, has widened the selling market of electronlmobil, for electronlmobil popularize and development provides strong technical guarantee.

Description of drawings

Fig. 1 is the electric functional block diagram of the utility model.

The specific embodiment

As shown in Figure 1, the utility model comprises these four parts of power supply 1, controller 2, conversion and control mechanism 3 and double-motor.Power supply 1 connects controller 2, and the output of controller 2 is through conversion and control mechanism 3 taps, first motor 4 and second motor 5.

Wherein, power supply 1 is conventional vehicular power-bottle; Controller 2 also is to adopt conventional structure, and is electrically connected with maintenances such as speed-regulating handle bar, brake power cutoff mechanism, car light, loudspeaker and steering hardware on the electronlmobil.

The essence of conversion and control mechanism 3 is electrical switch; Can adopt the handle push-and-pull to control the mechanical mechanism of formula and the fit form of electric switch (also can directly adopt the version of an electrical switch); So just can be under the controlling of handle; Carry out the conversion of switch contact, thereby realize single conversion and control that drives of double-motor.

Double-motor comprises that the operating voltage of first motor 4 and 5, two motors of second motor is identical and horsepower output is different, and the horsepower output that generally is controlled at second motor 5 gets final product than the scope of the horsepower output big 30-80% of first motor 4.As for the common electric automobile, first motor can adopt 48V, 350W, and second motor can adopt 48V, 500W; For the heavy type electronlmobil, first motor can adopt 48V, 500W, and second motor can adopt 48V, 800W.

Claims

1. double dynamical single-drive system of electronlmobil; Comprise power supply (1), controller (2) and motor; It is characterized in that; Said motor comprises that operating voltage is identical and first motor (4) and second motor (5) that horsepower output is different, and said first motor (4) and said second motor (5) are electrically connected with said controller (2) through conversion and control mechanism (3).

2. the double dynamical single-drive system of electronlmobil according to claim 1 is characterized in that the horsepower output of said second motor (5) is than the horsepower output big 30-80% of said first motor (4).
