Novel hybrid power system and driving mode of novel hybrid power system

Abstract

The invention discloses a novel hybrid power system and a driving mode of the novel hybrid power system. An output shaft of an engine is connected with a first electric motor through a one-way clutch, an output shaft of the first electric motor is connected with a first input shaft of a gearbox, an output shaft of a second electric motor is connected with a second input shaft of the gearbox, an electric control clutch is arranged between the first input shaft of the gearbox and the second input shaft of the gearbox, at least three gears of structures are arranged in the gearbox, the even number gear and the odd number gear are respectively arranged on the first input shaft and the second input shaft, and each gear of structures on the same input shaft realize the gear switching through a synchronizer. Through adopting the mode, the novel hybrid power system can realize various driving modes, and the goals of energy saving and emission reduction are reached. The double advantages of extended-range pure electric driving and the plugging-in hybrid motive power driving are realized, the pure electric driving can be realized by aiming at the crowded situation of urban work conditions, and the high-power driving output under the high-speed work condition can also be realized.

Description

technical field

[0001] The invention relates to the field of automobile power drive, in particular to a novel hybrid power system and its drive mode. Background technique

[0002] The hybrid drive system is the research focus of the automobile industry because of its good fuel-saving effect.

[0003] Since the hybrid power system is based on the traditional engine drive system, the drive and working conditions are adjusted by adding a motor, so as to optimize the economic performance of the system. Difficulty driving. Therefore, how to design the hybrid drive system structure becomes particularly important. A good drive system coupling structure can simplify the system complexity and operation difficulty, and increase the system's realizability.

[0004] The current mainstream deep hybrid structure is Prius of Toyota Motor and Volt of General Motors, both of them adopt planetary gear structure, the design is ingenious, but the structure is relatively complicated; Among the...
