The utility model content
Technical problem to be solved in the utility model is that a kind of motor vehicle driven by mixed power power drive will be provided, and is provided with motor in the gear box casing rear end, is provided with motor shaft and switchover apparatus in the change speed gear box, can effectively overcome the defective of prior art scheme.
In order to solve above technical matters, the utility model provides a kind of motor vehicle driven by mixed power power drive, comprise power-transfer clutch, change speed gear box, motor and ECU (Electrical Control Unit), the power-transfer clutch A end is connected with engine flywheel, the power-transfer clutch secondary part is connected with the change speed gear box input shaft, be provided with input shaft, tween drive shaft, output shaft, transmission gear and motor shaft in the change speed gear box, it is characterized in that: motor places the gear box casing rear end, and motor shaft is provided with switchover apparatus in the change speed gear box.
Switchover apparatus on the described motor shaft comprises synchro, declutch shift shaft and shift fork and automatically controlled selector device, and is installed in the middle part of motor shaft.
Described motor places the gear box casing rear end, adopts keysets to connect.
The utility model is by being provided with motor shaft in change speed gear box, and by switchover apparatus with motor power by gear transmission to input shaft or be directly delivered on the output shaft, when change speed gear box places neutral gear by the direct start the engine of motor.By the setting of motor shaft and switchover apparatus, during gear shift directly with transmission of power to the output shaft solving the power interruption problem, and when feedback braking, raise the efficiency.Motor power is directly delivered on the input shaft, utilizes the transmitting ratio of change speed gear box that the motor reduction of speed is increased and turns round, and improves climbing, low speed large throttle operating mode.Switchover apparatus can adopt mechanisms such as synchro or power-transfer clutch on the motor shaft, motor itself can active speed governing make these several mechanisms all possible in the use, the steering unit of switchover apparatus then can integrate with the gearshift of change speed gear box itself, interlocking between each gear of the gearshift of change speed gear box own, gear self-locking, the motor power switching mechanism is independent of gearbox selector and carries out powershift.The utility model can place drive motor outside the change speed gear box by establishing motor to the back-end at gear-box axle, thereby makes the increase of capacity motor become possibility.
The power-transfer clutch outputting power by input shaft, tween drive shaft and associated transfer gear system to the output shaft transmission, the motor outputting power by switchover apparatus and associated teeth train on motor shaft, the motor shaft respectively to input shaft and tween drive shaft transmission.Described Hybrid Vehicle driving device also comprises motor power shifter electric control operating mechanism, the automatically controlled selector device of change-speed box, the automatically controlled separation device of power-transfer clutch, electronic control unit.
The utility model is simple in structure, efficiently solves hybrid powder motor power input power-assisted problem, conveniently carries out spatial destribution when car load uses, and adapts to the desired various operating modes of hybrid electric vehicle complete vehicle better.
