Its working principle is as follows:
Engine-driving pattern I: after motor 19 startings, engine clutch 18 engages, motor 19 power are input to preceding planet carrier 4 through driving gear 16 and driven gear 3, because motor brake 2 is locked, preceding sun gear 14 lockings, and front ring gear break 6 and front ring gear clutch 8 are in separated state, front ring gear 5 is in idling conditions, transferring power not, motor 19 power import back gear ring 13 into by preceding planet carrier 4, are delivered to back planet carrier 10 through back planet wheel 7 again, because afterwards planet carrier clutch 9 is in jointing state, and rear sun gear 12 lockings, motor 19 power are by output shaft 11 outputs.
Engine-driving pattern II: after motor 19 startings, engine clutch 18 engages, motor 19 power are input to preceding planet carrier 4 through driving gear 16 and driven gear 3, because motor brake 2 is locked, preceding sun gear 14 lockings, and front ring gear clutch 8 is in jointing state, and front ring gear break 6 is in separated state, and motor 19 power are through preceding planet wheel 15, front ring gear 5 and output shaft 11 outputs.Because back planet carrier clutch 9 is in separated state, back planet carrier 10 is in idling conditions.
Motor drive mode I: after motor 1 starting, motor 1 power is directly delivered to preceding sun gear 14, since engine output shaft break 17 lockings, preceding planet carrier 4 lockings, and front ring gear break 6 and front ring gear clutch 8 are in separated state, front ring gear 5 is in idling conditions, transferring power not, motor 1 transmission of power are delivered to planet carrier 10 afterwards through back planet wheel 7 again to rear sun gear 12, because back planet carrier clutch 9 is in jointing state, motor 1 power is by output shaft 11 outputs.
Motor drive mode II: after motor 1 starting, motor 1 power is directly delivered to preceding sun gear 14, and front ring gear clutch 8 is in jointing state, and motor 1 power is through preceding planet wheel 15, front ring gear 5 and output shaft 11 outputs.Because back planet carrier clutch 9 is in separated state, back planet carrier 10 is in idling conditions.
Motor and motor drive mode I: three clutches all are in jointing state, three breaks all are in separated state, two-row planetary gear has only one degree of freedom, be equivalent to an entity, engine power and motor power are directly delivered on the output shaft 11 after being coupled by driving gear 16 and driven gear 3.
Motor and motor drive mode II: back planet carrier clutch 9 and three breaks all are in separated state, front ring gear clutch 8 and engine clutch 18 are in jointing state, back planet carrier 10 is in idling conditions, motor 19 power and motor 1 outputting power are delivered to front ring gear 5 through preceding sun gear 14, preceding planet carrier 4 after being coupled, again through front ring gear clutch 8 and output shaft 11 outputs.
Energy recovery pattern I: under this pattern, the executive component working state is finished consistent with the state under the motor drive mode I, the route of transmission of power also is the same, the direction of transfer of different is power is opposite, power is transmitted and is outputed to motor 1 by rear sun gear 12, preceding sun gear 14 by output shaft 11 input, and motor 1 is operated under the generating state, charge a battery, finish the recovery of braking energy.
Energy recovery pattern II: under this pattern, the executive component working state is finished consistent with the state under the motor drive mode II, the route of transmission of power also is the same, the direction of transfer of different is power is opposite, power is transmitted and is outputed to motor 1 by front ring gear 5, preceding planet wheel 15, preceding sun gear 14 by output shaft 11 input, and motor 1 is operated under the generating state, charge a battery, finish the recovery of braking energy.
Stopping for charging pattern: under vehicle stop state, output shaft 11 is lockings, because front ring gear clutch 8 is in jointing state, no matter which kind of state front ring gear break 6 is in, front ring gear 5 all is lockings, and motor 19 power pass through driving gear 16 and driven gear 3, preceding planet carrier 4, preceding planet wheel 15, preceding sun gear 14 successively, are input to motor 1, motor 1 is operated under the generating state, charges a battery.At this moment, because back planet carrier clutch 9 is separated, back planet carrier 10 is in idling conditions.
Engine-driving charge in batteries pattern: the state of executive component working state and motor drive mode II is on all four, motor 19 outputting power parts are used for powered vehicle and advance, remainder is exported to motor 1, and motor 1 is operated in generating state, to charge in batteries.
Motor starting engine mode: because front ring gear break 6 lockings, back planet carrier clutch 9 is separated, motor 1 outputting power drags motor 19 runnings through preceding sun gear 14, preceding planet wheel 14, preceding planet carrier 4, driven gear 3 and driving gear 16, engine clutch 18 successively, finishes motor 19 startings.
From above working principle as can be seen, adopt the hybrid vehicle of this electromechanical power coupling device can be operated in engine-driving, motoring, motor and motoring, energy recovery, stopping for charging, the engine-driving charge in batteries, the motor starting motor is totally 7 kinds of patterns, and engine-driving pattern, motor drive mode, motor and motor drive mode, the energy recovery pattern all has two kinds of alternative states, the all corresponding different speed ratios of each state, play the function of multi-speed gear box, and realized the compactness layout of vehicle drive system.
