Hybrid driving system with single prepositioned transmission shaft and rear drive axle

Abstract

The invention discloses a hybrid driving system with a single prepositioned transmission shaft and a rear drive axle. The technical scheme adopted by the invention lies in that the hybrid driving system with a single prepositioned transmission shaft and a rear drive axle comprises an engine, a first clutch, a second clutch, a motor, a gearbox and the rear drive axle, wherein the engine, the first clutch, the second clutch, the motor and the gearbox are arranged at the front part of an automobile body, and the rear drive axle is arranged at the rear part of the automobile body; rotating shafts are respectively arranged at two end parts of the motor, the rotating shaft at the front end part of the motor is connected with the engine through the first clutch, and the rotating shaft at the rear end part of the motor is connected with the gearbox through the second clutch; the other end of the gearbox is connected with the rear drive axle through the transmission shaft. A longitudinal space in front of and behind the complete automobile is fully used, so that the arrangement difficulty of the complete automobile is reduced, and the space of the complete automobile is saved. Besides, the power coupling and the work pattern switching of the complete automobile are realized, the requirements for travelling power performance of the automobile under different working conditions are met, and the purposes of being oil-saving and emission-reducing are achieved.

Description

technical field [0001] The invention relates to the field of hybrid power, in particular to a single-axis front and rear drive hybrid power drive system. technical background [0002] At present, hybrid vehicles are mainly gasoline-electric hybrid structures, and the drive system mainly includes engines, starter motors, drive motors, clutches, transmissions, control systems, etc. Due to the large number of components, the operation and layout of the system are very complicated. The power drive structures of hybrid electric vehicles mainly include series, parallel and hybrid structures. The serial hybrid vehicle requires two motors, which are respectively used as a driving motor and a generator; meanwhile, the serial structure is mainly driven by the driving motor, so that it cannot meet the requirements for higher driving. Both the parallel structure engine and the motor can drive the car, which can meet the driving requirements under different working conditions. The layo...
