Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model being elaborated, the present embodiment, premised on technical solutions of the utility model, gives detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment
Embodiment of the present utility model is as it is shown in figure 5, this utility model includes tooth rest 1, first sun gear 2, second sun gear 3, first planet gear 4, second planetary gear 5, coupling power set 6, engine flywheel 7, fly wheel brake 8, motor stator 9, rotor 10, the first sun gear 2, second sun gear 3 is arranged in tooth rest 1, first planet gear 4, second planetary gear 5 is arranged in the inside of tooth rest 1, coupling power set 6 are arranged on the sidewall of tooth rest 1, first planet gear 4 is meshed by external gear with the first sun gear 2, and the second planetary gear 5 is meshed by external gear with the second sun gear 3, first planet gear 4, second planetary gear 5 is coaxially connected, first planet gear 4, second planetary gear 5 is array and arranges, engine flywheel 7 is connected by connecting axle and the first sun gear 2, the outer ledge of engine flywheel 7 is embedded in fly wheel brake 8, and rotor 10 is connected with the second sun gear 3, and coupling power set 6 are PTO.
In implementation process of the present utility model, generally there are two kinds of conventional operating modes:
Operating mode one, when running whole vehicle starting, owing to low speed starts to be in inefficient district, so electromotor is in stopped status.By fly wheel brake 8, flywheel 7 being braked locking, the first sun gear 2 of co-axial connection is locked out simultaneously.Rotor 10 coaxially drives the second sun gear 3 to rotate together, and the second sun gear 3 drives the second meshing with it planetary gear 5 to rotate, with the coaxially connected first planet gear 4 of the second planetary gear 5 also together with rotate.Owing to the first sun gear 2 is by fly wheel brake 8 locking, so first planet gear the 4, second planetary gear 5 drives coupling power set 6 to do circumference planetary motion around the first sun gear 2.Therefore driving-chain is by rotor 10, to the second sun gear 3, tooth rest 1 is promoted side by side to the second planetary gear 5, first planet gear 4, by the few tooth reducing gear of the two-stage being made up of second sun gear the 3, second planetary gear 5, first planet gear the 4, first sun gear 2, realize the reasonable speed reducing ratio of target demand, promote the output demand power of coupling power set 6.
Operating mode two, when running car load and entering electromotor optimum oil consumption optimum discharge region, fly wheel brake 8 discharges, and rotor 10 does retarded motion.Due to differential principle, the rotating speed of coupling power set 6 is equal to: the second sun gear 3 rotating speed is multiplied by and removes two relative to the first sun gear 2 speed ratio plus the first sun gear 2 rotating speed.So the deceleration of rotor 10, bring engine flywheel 7 speedup, it is achieved engine start participates in hybrid power coupling output.When driving vehicle load changes, motor can serve as power governor thus realizing starting to always work at optimum working zone to realize the purpose of energy-saving and emission-reduction.
