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

Abstract

The invention discloses a new-typed double-motor series-parallel composite dynamic set, which comprises the following parts: generator, ISG motor, clutch, variator, main driving motor and main decelerator of driving bridge, wherein the generator integrates ISG motor with ISG motor fixed on the generator crank, the motor variator couples, which integrates with driving motor, the driving motor outputs torque on the variator output shaft through coupling pattern, the power is transmitted to wheel through main-decelerator of driving bridge.

Description

Technical field: [0001] The invention relates to a power assembly of a hybrid electric vehicle, in particular to a novel dual-motor hybrid power assembly, 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...
