Abstract

The invention discloses a driving device of a hybrid electric vehicle with a gear box and a driving method thereof. The driving device comprises an engine, a driving motor and a main clutch. The output end of a generator is connected with the input end of the main clutch, and the output end of the main clutch is connected with the input end of the driving motor. The driving device further comprises the gear box, the output end of the driving motor is connected with the input end of the gear box, the output end of the gear box is connected with a transmission shaft, a first gear and a third gear in the gear box are meshed, a second gear is meshed with a fourth gear, the first gear is in transmission connected with the second gear through a first auxiliary clutch, and the third gear is in transmission connection with the fourth gear through a second auxiliary clutch. The driving device and the driving method have the advantages that (1) output torque of the driving motor can be increased; (2) the gear box can increase rated speed of the driving motor; (3) the gear box adopts the air control mode or the liquid control mode to control the clutches; (4) the working condition saving oil most can be achieved by using the gear box; (5) vehicle braking recycle quantity is increased; and (6) the gear box is quick in gear shifting and strong in adaptability.

Description

technical field [0001] The invention relates to a driving device of a hybrid electric vehicle, in particular to a driving device of a hybrid electric vehicle with a gearbox and a driving method thereof. Background technique [0002] Existing hybrid vehicles are independently driven by a drive motor or an engine, and some are jointly driven by a drive motor and an engine. When the drive motor is used to drive alone, the drive motor can output the corresponding maximum torque and exert the maximum effect only at the rated speed, but the running speed of the vehicle is variable, so it is difficult to exert the maximum effect when driven by the drive motor. [0003] When the current hybrid vehicle brakes, the inertial kinetic energy of the vehicle is generated by the drive motor for energy-consuming braking. However, as the vehicle decelerates, the power generated by the drive motor decreases as the speed decreases. At the same time, the current gasoline-electric hybrid vehicle...
