Description
Technical field
The invention belongs to new forms of energy hybrid power automobile power assembly technical field, particularly to one based on whole
The hybrid power assembly device of car P2 configuration.
Background technology
For power assembly design arrangement in car load, industry is divided into P1 car load hybrid power configuration,
The various structures forms such as P2, P3, P4, Power split.P2 configuration is to be arranged in driving motor to start
Between machine and change speed gear box, separate a kind of configuration after clutch.
Hybrid power assembly device based on P2 configuration, substantially by electromotor, separation clutch, driving electricity
Machine and change speed gear box are constituted.In conjunction with power transfer path, currently mainly there are two kinds of designs.One is to send out
Motivation, separation clutch, driving motor and change speed gear box are sequentially connected in series；Another kind is by electromotor, divides
Luxuriant clutch and change speed gear box are sequentially connected in series, and drive motor to be arranged in change speed gear box side, by belt or
Chain connects.
For the mixed power plant of the first design, as it is shown in figure 1, electromotor 1, former separation clutch
Device 2, former driving motor 3 and change speed gear box 4 are connected in series, and the axial space so needed is bigger.For car load
Power assembly is horizontal, is difficulty with arranging；Longitudinal for car load power assembly, need to increase in lengthening vehicle body
Passage is protruding, the comfortableness that impact is driven and taken.
For the mixed power plant of the second design, as in figure 2 it is shown, electromotor 1, separation clutch
2 and change speed gear box 4 be sequentially connected in series, drive motor 3 be arranged in change speed gear box side, by belt or chain
Connect.Although solving the problem that hybrid power assembly is the most long, but owing to driving motor to be arranged in change
Speed case side, by belt or chain drive, the radial space of needs is the biggest.For car load power assembly
Longitudinal, affect the layout of body platform, the manipulation space affecting driver and the comfortableness taken.
Simultaneously drive motor with change speed gear box by belt or chain drive, due to belt and the draftability of chain,
When car load transmission load changes, easily there is shake in drive system, affects the control stability of car load
And comfortableness, particularly after belt and chain wear extend, shake then becomes apparent from.
Additionally, the hybrid power assembly device of both the above design is the layout adapting to car load, structure is all
That does is the most complicated, and the degree of modularity is low, assembling inconvenience.And nearly all use brand-new design, and tradition
The common platform of car is poor, and cost is high.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide a kind of used in new energy vehicles based on car load P2 configuration and mix
