Background technology
At present, energy scarcity and environmental problem have turned into the topic of whole world growing interest, as close with the energy, environment
Related automobile industry is, it is necessary to paces immediately following world development, and development is more efficient, and more environmentally-friendly automobile has been current
One trend.Various types of new, the automobile such as hybrid vehicle of energy-conservation, electric car, fuel cell car develops one after another
Out.But restricted by technical conditions, electric automobile, fuel cell car is also difficult to volume production popularization in the recent period, and mixes dynamic
Power automobile current technology has developed slightly ripe, such as pure electronic and fuel cell car a transition side
Case, oil electricity, gas-electricity power combined automobile is instantly ideal selection.
Hybrid vehicle (HEV) is a kind of energy-efficient, environment-friendly automobiles, as the earliest skill developed and promoted on automobile
Art, relative to orthodox car, pure electric automobile, the characteristics of its is main, includes containing engine system in dynamical system again
Electric system.The difference of both combining form, has derived series connection, in parallel, a variety of drive forms such as series-parallel connection.Go back handle simultaneously
Gearbox gear transmission is included in dynamical system together so that power resources and distribution more diversification, capacity usage ratio is more
Height, adaptability are wider.The small volume that wherein planetary gear train has, quality is small, compact-sized, and bearing capacity is strong, power transmission and
Transmission range is big, causes planetary gear train extensive use in automotive power transmission system, and hybrid power the features such as efficiency high
Development trend.This for example general sharp power dividing form of current existing technology, point speed remittance square, single planetary row, no-clutch, double electricity
Mechanism type.Audi A3e-tron parallel-connection structure, DCT speed changers, single motor, P2 configurations.And the parallel connection that BYD-Qin uses
Configuration, 6 Quick-drying type DCT, structure, etc. is coupled after single motor transmission, be all the configuration of in the market comparative maturity.As shown in figure 1,
