Embodiment Construction

[0013] exist figure 1 , 2 In the illustrated embodiment, the parallel hybrid system mainly includes an engine drive and an electric drive. The engine driving devices are all connected together by the engine through the clutch 12, the transmission 13, the differential 14a, the axle shaft 14 and the wheels 16 in sequence. The electric drive device is mainly electrically connected together by a compound excitation DC motor 8 , a storage battery 4 and a power conversion controller 6 . The compound excitation DC motor 8 is sequentially connected together through the differential gear 5a, the axle shaft 5 and the wheels 17. A speed sensor 3 is installed at the output end of the engine, and a vehicle speed sensor 7 is installed at the shaft end of the compound excitation DC motor 8 . The ECU control unit 2 is electrically connected with the engine, the rotational speed sensor 3 , the vehicle speed sensor 7 , the electric energy conversion controller 6 and the clutches 10 and 12 . ...

Abstract

The invention discloses a parallel connective mixing power system and belongs to the power equipment of the communication transportation field. The system mainly comprises the driving device of the engine and the electric driving device. Because the driving device of the engine adopts at least two generators, so it can joint and separate the engine and adapt the output load of the engine to the outside load. The electric driving device adopts the multiple field DC electric machines, and if the ECU control unit changing the excitation patterns the multiple fields DC electrical machines can be used as the electric generator or the electromotor. The system according to the steering situation use ECU control unit to optimize the control to further improve the efficiency of the system.

Description

technical field [0001] The invention relates to a parallel hybrid power system widely applicable to variable working conditions and variable load power devices, which belongs to the field of power devices for transportation. Background technique [0002] As we all know, in a hybrid power system, there are three modes of power transmission, namely series mode, parallel mode and hybrid mode. The series mode is to use the engine to drive the generator, and the generator drives the motor through the generated electricity, and the motor drives the wheels. In this way, the engine with a small output power can run more stably within the effective range, and the vehicle is still stable. It is possible to drive while efficiently charging the battery. The parallel mode is to drive the wheels with the engine and the electric motor, which can use the two powers separately or simultaneously according to the driving conditions. Toyota's hybrid power system combines the parallel mode and...
