Detailed description of the invention
Elaborate to embodiments of the invention below in conjunction with accompanying drawing, the present embodiment, premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
embodiment
Embodiments of the invention as shown in Figure 5, the present invention includes tooth rest 1, first sun wheel 2, second sun wheel 3, first planet gear 4, second planetary wheel 5, coupling power device 6, engine flywheel 7, fly wheel brake 8, motor stator 9, rotor 10, the first sun wheel 2, second sun wheel 3 is arranged in tooth rest 1, first planet gear 4, second planetary wheel 5 is arranged in the inside of tooth rest 1, coupling power device 6 is arranged on the sidewall of tooth rest 1, first planet gear 4 is meshed by external gear with the first sun wheel 2, and the second planetary wheel 5 is meshed by external gear with the second sun wheel 3, first planet gear 4, second planetary wheel 5 is coaxially connected, first planet gear 4, second planetary wheel 5 is array and arranges, engine flywheel 7 is connected with the first sun wheel 2 by adapter shaft, the outer ledge of engine flywheel 7 is embedded in fly wheel brake 8, and rotor 10 is connected with the second sun wheel 3, and coupling power device 6 is power take-off implement.
In implementation process of the present invention, usually there are two kinds of conventional operating modes:
Operating mode one, when operational vehicle car load is started to walk, because low speed starts to be in low efficiency district, so driving engine is in stopped status.Carry out brake lock by fly wheel brake 8 pairs of flywheels 7, coaxial the first sun wheel 2 connected is simultaneously by locking with it.Rotor 10 coaxially drives the second sun wheel 3 to rotate together, and the second sun wheel 3 drives the second meshing with it planetary wheel 5 to rotate, with the coaxial first planet gear 4 connected of the second planetary wheel 5 also together with rotate.Because the first sun wheel 2 is by fly wheel brake 8 locking, so first planet gear 4, second planetary wheel 5 drives coupling power device 6 to do circumference planet motion around the first sun wheel 2.Therefore messenger chain is by rotor 10, to the second sun wheel 3, tooth rest 1 is promoted side by side to the second planetary wheel 5, first planet gear 4, by the few tooth speed reduction gearing of the two-stage be made up of the second sun wheel 3, second planetary wheel 5, first planet gear 4, first sun wheel 2, the reasonable reduction ratio of realize target demand, promotes the output demand power of coupling power device 6.
Operating mode two, when operational vehicle load enters driving engine optimum oil consumption optimum discharge region, fly wheel brake 8 discharges, and rotor 10 does decelerated movement.Due to differential principle, the rotating speed of coupling power device 6 equals: the second sun wheel 3 rotating speed is multiplied by and adds that the first sun wheel 2 rotating speed is except two relative to the first sun wheel 2 speed ratio.So the deceleration of rotor 10, bring engine flywheel 7 speedup, realize engine starting and participate in hybrid power coupling output.When driving vehicle load changes, motor can serve as power governor thus realize starting to be operated in the object that optimum working zone realizes energy-saving and emission-reduction always.
