Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
First embodiment
Referring to Fig. 1, the starting mechanism of this motor car engine, comprise the generator 3 that is used to drive motor 1, generator is electrically connected with storage battery 12, see Fig. 3, motor shaft is in transmission connection by power flywheel 6 and motor, be in transmission connection by power clutch 8 between power flywheel and the engine power axle, also be connected with startup flywheel 5 on its engine power axle, start flywheel and be in transmission connection by the motor shaft that starts clutch 7 and driving mechanism 4 and power flywheel and generator respectively by overrunning clutch 9.The line shaft of motor stretches out from the motor body one or both ends, starts on the coaxial arbitrary end that is arranged on line shaft of flywheel and power flywheel.
Referring to Fig. 3 and Fig. 4, generator is an alternator, one group of break contact KM1 and moving together contact KM2 by magnetic switch are electrically connected with rectification circuit 13 and inverter circuit 14 respectively, magnetic switch coil KM, rectification circuit and inverter circuit are connected electrically on the storage battery 12, and the storage battery electrode output is electrically connected with main switch S.
Above-mentioned driving mechanism 4 is gear or pulley transmission mechanism, is in transmission connection with motor shaft and startup flywheel 5 respectively; The first switch S B1 can for the switch of braking device interlock or delay switch or the switch that is connected with the Computerized intelligent system; Second switch SB2 is the switch that links with gear.
Its working principle is: the motor of establishing original state stops, and (second switch SB2 can when neutral, close for being arranged on the switch on the Motor Vehicle gear for the circuit general switch S that closes, enable switch SB, the first switch S B1 and second switch SB2; During non-neutral, open), relay coil KA energising, so, its three normally open contact KA1, KA2, KA3 be closure all, makes magnetic switch coil KM energising (break contact KM1 disconnects with rectification circuit 13 and is connected moving together contact KM2 and inverter circuit 14 conductings), 7 energisings of startup clutch (switch on and engage, outage is left) and power clutch 8 energisings (energising is left, and outage engages).At this moment, storage battery 12 provides high-frequency alternating current (greater than 100Hz) by inverter circuit 14 and moving together contact KM2 for motor 3, make its high speed rotating, motor shaft is successively by driving mechanism 4, start flywheel 5 and start clutch 7 and drive power flywheel 6 acceleration, accelerate to when meeting motor 1 and starting needed rotating speed (generally setting rotating speed changes at per minute 5000 to 5500), speed switch 2 disconnects (when generator reaches the setting rotating speed, speed switch disconnects, do not reach when setting rotating speed, speed switch is a connected state), but because enable switch SB is in closed state, and it is in parallel with speed switch, so power flywheel continues to fly to change on this high speed, wait for engaging with motor 1 line shaft.
During ato unit, open enable switch SB, power clutch 8 is coupling with engine power and closes, (behind the engine start, when the Motor Vehicle gear entered into non-neutral state, Motor Vehicle can move ato unit 1, simultaneously, because the second switch SB2 when gear is in non-neutral state opens, guaranteed that further the normally open contact KA3 that connects power clutch 8 opens, and closes power clutch all the time); Then, open the first switch S B1, relay coil KA outage, its three normally open contact KA1, KA2, KA3 all open simultaneously, make break contact KM1 and rectification circuit 13 conductings respectively, moving together contact KM2 disconnects with inverter circuit 14 and being connected, and starts clutch 7 and leaves, the line shaft of motor drives generators 3 and rotates by overrunning clutch 9, startup flywheel 5, driving mechanism 4 successively, and generator charges for storage battery 12 by break contact KM1 and rectification circuit 13.
When not needing engine power, by brake engine speed is reduced, generator 3 rotating speeds are followed reduction, speed switch is connected, then, enable switch SB simultaneously closes, the first switch S B1 and second switch SB2, make relay coil KA, power clutch 8, start clutch 7 and magnetic switch coil KM and be in "on" position once more, power clutch 8 separates with the engine power axle, and motor quits work because of unpowered flywheel 6 drives, and generator and inverter circuit join, accelerate to rotating speed of target for starting flywheel and power flywheel, speed switch is opened, and the engine start condition is finished, and the wait enable switch opens ato unit.
