If this organization plan as the platform of plug-in hybrid car, then also is connected with a charging unit on electrokinetic cell.
The startup generating integral type motor (BSG) of belt drive is by its output shaft and motor pulley and belt train bonded assembly, we can say that also this motor pulley has become the part in the belt train.
Change speed gear box can use various types: Automatic Transmission (AT), stepless change Automatic Transmission (CVT), automation change speed gear box (AMT), double-clutch automatic speed-change case (DCT) etc.The speed ratio of change speed gear box changes and gearshift automatic guidance on opportunity, can realize the optimal control of speed ratio.
Electrokinetic cell can use Ni-MH battery, lithium ion battery etc., and parameters such as its capacity, specific power if this platform is used to develop the plug-in hybrid car, need to increase charging unit by the design plan and the decision of realization target of hybrid power.
The attainable function of this hybrid architecture scheme mainly comprises: the startup generating integral type motor quick operated start driving engine of belt drive, this integral type motor drive former car appendix, driving engine independent drive, main motor independent drive, driving engine and main motor and drive, reclaim braking energy, engine drive electric power generation etc. jointly when tail-off.
The technical solution of the utility model has following advantage:
It also is not very ripe mechanism's product that the utility model does not use electric air-conditioning compressor, electric powered steering etc., and the reliability service of each appendix when using the appendix of former car to realize tail-off helps quick industrialization.
This utlity model has very strong commonality, can be used for developing full hybrid vehicle or plug-in hybrid fully.The electromechanical coupling scheme adopts and has coupling in wheel chain formula or the gear-driven torque synthesizer, can realize the repertoire of full hybrid vehicle or plug-in hybrid car.
The utility model also has simple in structure, convenient operating maintenance, the flexible arrangement of motor, characteristics such as cost is low, and field of application is wide.
