Problems solved by technology
The series type has the advantages of simple structure and easy control, but at the same time has the disadvantages of low efficiency and high cost, which restricts its application and promotion; for passenger cars, the parallel type is generally used for mildly mixed A-class or below A-class passenger cars ; For B-class and above models, the hybrid type is often used. It has a complex structure and is difficult to control, but it has the best fuel-saving effect

Embodiment Construction
[0011] The present invention will be described in further detail below in conjunction with accompanying drawing, as figure 1 As shown, the new dual-motor hybrid powertrain is composed of engine 1, ISG motor 2, clutch 3, transmission 5, drive motor 6, and drive axle main reducer 4; its feature is that engine 1 and ISG motor 2 are integrated Together, the ISG motor 2 is fixed on the engine crankshaft 11; the drive motor 6 and the transmission 5 are integrated together, the drive motor 6 is coupled with the gear of the transmission output shaft to output the torque to the transmission output shaft 51, and the power finally passes through the drive axle final drive 4. Pass to the wheel.
[0012] Such as Figure 1-4 As shown, the drive motor 6 and the output shaft 51 of the gearbox 5 can achieve torque synthesis in different ways. figure 1 Shown is that the drive motor 6 is directly connected to the output shaft 51 rear end of the speed changer 5, and the drive motor 6 is made in...

The invention relates to a novel double motor parallel-serial hybrid assembly and a system. The novel double motor parallel-serial hybrid assembly consists of an engine, an ISG motor, a clutch, a speed changer, a main driving motor and a drive axle main reducing gear, and is characterized in that the engine and the ISG motor are integrated into a whole and the ISG motor is fixed on a crankshaft of the engine; and the motor and the speed changer are integrally coupled, the driving motor is integrated with the speed changer into a whole and outputs torque to an output shaft of the speed changer through a coupling mode, and power is transmitted to wheels through the drive axle main reducing gear finally. The novel double motor parallel-serial hybrid assembly and the system have the advantages of a novel and compact structure, serialization, and easy realization of mixing degree in various degree, and can be arranged on front-engine front-drive and front-engine rear-drive automobiles so as to improve service performance and fuel economy and realize low emission of hybrid automobiles.
Description
Technical field: [0001] The invention relates to a novel dual-motor hybrid power assembly and system, which is a power assembly for a hybrid electric vehicle using fuel and electricity as energy sources. Background technique: [0002] At present, there are three types of hybrid electric vehicle powertrain configurations: series, parallel and hybrid. The series type has the advantages of simple structure and easy control, but at the same time has the disadvantages of low efficiency and high cost, which restricts its application and promotion; for passenger cars, the parallel type is generally used for mildly mixed A-class or below A-class passenger cars ; For B-class and above models, the hybrid type is often used. It has a complex structure and is difficult to control, but it has the best fuel-saving effect. Invention content: [0003] The purpose of the present invention is to provide a new dual-motor hybrid powertrain and system, which integrates the driving motor and t...
