In Fig. 1, when vehicle need travel, depress brake petal 23, ato unit, at this moment with the synchronous machine 13 of brake petal interlock and the control switch closure of magnetic clutch 11, make synchronous machine 13 and magnetic clutch 11 get electric work, synchronous machine 13 drives synchromesh gear 12 and drives gear ring 8 by magnetic clutch 11,5 runnings of eccentric type planet wheel, central gear 4 and synchronous coupling driven disc 16 are turned round to equidirectional with synchronous coupling driving disc 15, because the rotating speed of motor is more high, the voltage of generator output is more high, the rotating speed that drives synchronous machine 13 runnings is also more high, the speed ratio that planetary gear set reaches and central gear 4 coaxial mounted driven discs 16 turn round that drives in the clutch because of synchronous machine 13 is certain again, the synchronization of it and motor, thereby make the master of coupling, the rotating speed of driven disc is consistent or is fast slightly, because the height difference at the boss two ends of synchronous coupling driven disc 16, its this structural characteristics, determined to have only driven disc 16, drive synchromesh gear 12 and planetary gear set running at synchronous machine 13, make the rotating speed of the rotating speed of driven disc and driving disc reach one to or when the driving disc of surmounting rotating speed trend was arranged, principal and subordinate's Moving plate could mesh under the effect of shift fork.When Transmission gear handle 24 pushes the gear that travels, switch on the shift fork drive unit of its interlock, at this moment shift fork drive unit driving synchronous coupling driving disc 16 is moved to the left with synchronous coupling driving disc 15 and engages, drive the planetary gears running for input shaft 2 transmission of power, when lifting brake petal, synchronous machine 13 dead electricity will be braked, while magnetic clutch 11 also dead electricity separates gear ring 8 with synchromesh gear 12, because the power of motor and planetary gear set running action of inertia, synchronous machine 13 is locking suddenly not, (can adopt the mode of braking that synchronous machine is applied backward voltage in actual applications but brake gradually until stopping operating, here be that illustrative ease adopts this mode of braking temporarily), this process also makes power impel vehicle to finish starting-up process by the running of output shaft 3 drive speed transmission, when synchronous machine 13 is braked gradually, be subjected to the effect of clamping down on of free wheel device 10, gear ring 8 also will stop operating gradually, power is by central gear 4, eccentric type planet wheel 5, output shaft 3 runnings are to the speed changer transferring power, also revolve round the sun around central gear 4 in the time of the driving generation rotation of eccentric type planet wheel 5 acceptor center gears 4 at this moment, because the structural characteristics of eccentric type planet wheel 5 produces centrifugal force in its rotation with in the process of central gear 4 revolution, this centrifugal action is on planetary wheel carrier 7 and central gear 4, they are controlled, raising along with the rotating speed of input shaft 2 and output shaft 3, the rotation of eccentric type planet wheel 5 and revolution rotating speed also further strengthen, the also corresponding increase of centrifugal force that it produces, simultaneously to planetary wheel carrier 7, central gear 4 produces bigger control force, when the rotating speed of input shaft 2 and output shaft 3 reaches certain rotating speed, the centrifugal force of eccentric type planet wheel 5 generations of revolution pins central gear 4 and planetary wheel carrier 7 gradually at a high speed, at this moment powerful centrifugal force makes the eccentric type planet wheel 5 can not rotation, can only be around central gear 4 revolution, central gear 4 and planetary wheel carrier 7 turn round in the same way with speed, also drive simultaneously gear ring 8 in the same way with the speed running, at this moment, free wheel device 10 also loses the effect of clamping down on to gear ring 8, thereby realize planetary gear set integral body in the same way, with the speed running, clutch has just been finished the engaging process driving normal vehicle operation of motor to the speed changer transferring power like this.
When vehicle need stop to travel, depress brake petal 23, the speed of a motor vehicle reduces, engine speed also reduces, when the speed of a motor vehicle drops to a certain degree, central gear 4 in the clutch unit, planetary wheel carrier 7 and gear ring 8 will withdraw from automatically in the same way with fast operating condition, service performance according to common planetary gear set turns round, gear ring 8 also will reduce rotating speed gradually until carrying out the direction running opposite with central gear 4 rotation directions, be subjected to the control with the control switch of the synchronous machine 13 of brake petal interlock simultaneously, make synchronous machine 13 drive synchromesh gear 12, to the direction running opposite with output shaft 3 rotation directions, so that it is synchronous with rotating speed and the direction of gear ring 8, when vehicle is subjected to the effect of braking force to stop to travel, clutch will be in the separated in synchronization state automatically, when the gear handle 24 of vehicle is allocated to parking retaining (P) position, at this moment shift fork is subjected to and retaining (P) the shift fork drive unit closure that links of stopping, the action of shift fork drive unit, shift fork moves to right and resets, synchronous coupling driven disc 16 separates with synchronous coupling driving disc 15, realizes the separating fully of power of motor and speed changer.
The above only is the schematic embodiment of the utility model; be not in order to limit scope of the present utility model; any those skilled in the art is not breaking away from scope of the present utility model; equivalent variations and modification that any those skilled in the art makes under the prerequisite that does not break away from the utility model design and principle all should belong to the scope that the utility model is protected.
