Detailed description of the invention
As shown in Figure 1, a kind of Double-power coupling driving system for pure electric automobile described in the embodiment of the present invention, comprise auxiliary drive motor 1 and main drive motor 2, described auxiliary drive motor 1 is connected with transmission gear 1 by transmission shaft 1, transmission gear 1 is connected with a joggle with reverse gear 1, reverse gear 1 is connected with output shaft gear 1, output shaft gear 1 is arranged on output shaft 7, main drive motor 2 is connected with transmission gear 29 and transmission gear 3 10 respectively by transmission shaft 28, the inside of transmission gear 29 is provided with single clutch 1, the inside of transmission gear 3 10 is provided with and turns to the free-wheel clutch contrary with free-wheel clutch 12 17, being connected with a joggle with output shaft gear 2 12 of transmission gear 29, output shaft gear 2 12 is arranged on described output shaft 7, transmission gear 3 10 is connected with a joggle with reverse gear 2 13, reverse gear 2 13 is connected with a joggle with output shaft gear 3 14, output shaft gear 3 14 is arranged on described output shaft 7, output shaft 7 is connected with vehicle bridge 15, vehicle bridge 15 is connected with wheel 16.
When concrete use, the inside of transmission gear 29 and transmission gear 3 10 is respectively equipped with free-wheel clutch 1 and free-wheel clutch 2 17, or the inside of transmission gear 29 and transmission gear 3 10 is connected with free-wheel clutch one 11 free-wheel clutchs 2 17 respectively, the opposite direction but the inner or coupled free-wheel clutch 1 of transmission gear 29 and transmission gear 3 10 and free-wheel clutch 2 17 work.And auxiliary drive motor 1 by transmission shaft 1, transmission gear 1, reverse gear 1 and output shaft gear 1 by power transmission to output shaft 7 and then pass to vehicle bridge 15, the power of main drive motor 2 under two different speed ratios respectively by transmission gear 29, output shaft gear 2 12 and transmission gear 3 10, reverse gear 2 13, output shaft gear 3 14 by transmission of power to output shaft 7 and then import vehicle bridge 15 into.
Operating mode one:
When auxiliary drive motor 1 rotates according to clockwise direction, main drive motor 2 rotates according to anticlockwise direction, now auxiliary drive motor 1 and main drive motor 2 are all in mode of operation, the power of auxiliary drive motor 1 is through transmission shaft 1, transmission gear 1, reverse gear 1 is delivered on output shaft 7, and the power of main drive motor 2 is through transmission gear 29, output shaft gear 2 12 is delivered on output shaft 7, now the moment of output is auxiliary drive motor 1 and main drive motor 2 stack of output torque separately, due to transmission gear 29, the speed ratio of output shaft gear 2 12 is larger, this kind of operating mode is applicable to the situation of low-speed big, therefore can meet the requirement of maximum climbing.Transmission gear 3 10 is passive freely rotating under this operating mode.
When drag, motor controller controls motor is in power generation mode, energy, through output shaft 7, reverse gear 1, transmission gear 1, transmission shaft 1 and output shaft gear 2 12, transmission gear 29 inputting assistant drive motor 1 and main drive motor 2 respectively, is then passed to closed-center system.
Operating mode two:
