The specific embodiment
As shown in Figure 1, the described a kind of pure electric automobile of the utility model embodiment is used double dynamical coupling drive system, comprises auxilliary drive motor 1 and main drive motor 2; Said auxilliary drive motor 1 is connected with transmission gear 1 through transmission shaft 1; Transmission gear 1 is connected with a joggle with reverse gear 1, and reverse gear 1 is connected with output shaft gear 1, and output shaft gear 1 is arranged on the output shaft 7; Main drive motor 2 is connected with transmission gear 29 and transmission gear 3 10 respectively through transmission shaft 28; The inside of transmission gear 29 is provided with single clutch 1, and the inside of transmission gear 3 10 is provided with and turns to the free-wheel clutch two 17 opposite with free-wheel clutch 1, being connected with a joggle with output shaft gear 2 12 of transmission gear 29; Output shaft gear 2 12 is arranged on the described output shaft 7; Transmission gear 3 10 is connected with a joggle with reverse gear 2 13, and reverse gear 2 13 is connected with a joggle with output shaft gear 3 14, and output shaft gear 3 14 is arranged on the described output shaft 7; Output shaft 7 is connected with vehicle bridge 15, and vehicle bridge 15 is connected with wheel 16.
During concrete the 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; Perhaps 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, but transmission gear 29 works in the opposite direction with the transmission gear 3 10 inner or coupled free-wheel clutchs that connect 1 with free-wheel clutch 2 17.And auxilliary drive motor 1 is given power transmission output shaft 7 and then is passed to vehicle bridge 15 through transmission shaft 1, transmission gear 1, reverse gear 1 and output shaft gear 1, the power of main drive motor 2 under two different speed ratios respectively through transmission gear 29, output shaft gear 2 12 and transmission gear 3 10, reverse gear 2 13, output shaft gear 3 14 with transmission of power to output shaft 7 and then import vehicle bridge 15 into.
Operating mode one:
When auxilliary drive motor 1 rotates according to clockwise direction; Main drive motor 2 is according to anticlockwise motion; This moment, auxilliary drive motor 1 all was in mode of operation with main drive motor 2; The power of auxilliary drive motor 1 is delivered on the output shaft 7 through transmission shaft 1, transmission gear 1, reverse gear 1; And the power of main drive motor 2 is delivered on the output shaft 7 through transmission gear 29, output shaft gear 2 12, and the moment of output this moment is auxilliary drive motor 1 and main drive motor 2 stack of output torque separately, because the speed ratio of transmission gear 29, output shaft gear 2 12 is bigger; This kind operating mode is fit to the situation of low-speed big, therefore can satisfy the requirement of maximum climbing.Transmission gear 3 10 is passive freely rotating under this operating mode.
During drag; The motor controller controls motor is in power generation mode; Energy is imported auxilliary drive motor 1 and main drive motor 2 respectively through output shaft 7, reverse gear 1, transmission gear 1, transmission shaft 1 and output shaft gear 2 12, transmission gear 29, passes to closed-center system then.
Operating mode two:
When main drive motor 2 clockwise rotates; Transmission gear 29 is free to slide; The power of auxilliary drive motor 1 and main drive motor 2 is passed to output shaft 7 through transmission shaft 1, transmission gear 1, reverse gear 1 and transmission gear 3 10, reverse gear 2 13, output shaft gear 3 14 respectively; Import vehicle bridge 15 then into, the speed ratio of transmission gear 3 10 is less, and can obtain higher output speed this moment; Output torque still is the stack of auxilliary drive motor 1 and main drive motor 2 output torques, meets the working condition requirement of the higher speed of a motor vehicle.
Glancing impact, auxilliary drive motor 1 is in power generation mode with main drive motor 2, and energy returns to closed-center system (battery).
Operating mode three:
In auxilliary drive motor 1 and main drive motor 2 any one works independently and all can satisfy the vehicle ' requirement; This moment, the another one motor was in charge mode; The torque part of work drive motor output is used for powered vehicle and goes; Another part is delivered to another motor through transmission system and makes its generating, charges to closed-center system.
Because an independent machine operation can powered vehicle be gone, therefore if wherein any one motor break down do not influence vehicle continue go.The more single motor-driven of reliability further improves.Energy then carries out feedback through two motors during brake.
Operating mode four:
The realization of reversing gear realizes through auxilliary drive motor 1 counter-rotating.
The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technical scheme, all drops within the protection domain of the utility model.
