Problems solved by technology

Its disadvantage is that only when the engine speed is close to the motor speed, the motor output shaft and the engine crankshaft can effectively transmit power, which will make it difficult to realize the main hybrid function of using the motor to quickly start the engine to reduce fuel consumption and emissions. Fuel saving and emission reduction is difficult to optimize

Abstract

The invention belongs to the technical field of automobiles and particularly provides a suspended parallel hybrid power-driven system with double clutches and double motors. The system comprises an engine, two clutches, two electric-control actuating mechanisms for the clutches, motors, a gearbox, a deceleration differential, two driving half-axles, two wheels, an energy storage unit, a motor control unit and a starting motor, wherein the engine is connected with the rotors of the motors via a first clutch and a transmission shaft; the rotors of the motors are connected with the gearbox, the deceleration differential, the driving half-axles and the wheels via a second clutch and are supported on a shell; and the two clutches are respectively under the automatic control of the two electric-control actuating mechanisms for the clutches. The invention can reduce the gaps between the stators and rotors of the motors and eliminate the adverse effects of vibration of the transmission system on engines and motors, has the operation modes of pure-electricity drive, smart charging and parallel full-hybrid power and has the advantages of high efficiency, easy drive, low cost and high reliability.

Description

technical field [0001] The invention relates to a system in the technical field of automobiles, in particular to a dual-clutch motor suspension parallel hybrid drive system. Background technique [0002] The structural types of automotive hybrid systems include series, parallel and hybrid. Due to the low cost of the parallel hybrid power system and the obvious advantages in performance and price ratio, most of the hybrid electric vehicles in the industrial development currently adopt the parallel system scheme. However, the existing parallel hybrid power system, such as the most representative IMA hybrid power system of Japan's Honda Motor Company, directly connects the motor rotor to the engine crankshaft flange, which not only needs to improve the engine crankshaft support and structure, but also Due to crankshaft vibration and other reasons, the gap between the stator and rotor of the motor should not be too small, which will limit the improvement of the motor efficiency...
