The transmission engaging mechanism is made up of shift fork 15, front cover 16, overrunning clutch 17, retainer axle 18, ring gear 19, four planetary pinions 30.
Please refer to Fig. 3, Fig. 4, Fig. 5, overrunning clutch 17 is made up of the tooth axle of sleeve 21, hub splines 22, band actuation gear 23, sleeve 21 is arranged in the front cover 16, sleeve 21 inboards are evenly equipped with cavity, roller 24 and inclined to one side spring 25 are installed in the cavity, spring 25 replaces roller 24 at the narrower place of cavity partially, hub splines 22 is inlaid in the sleeve 21, the middle part axostylus axostyle of retainer axle 18 is provided with external splines 26, this external splines 26 is inserted in the hub splines 22, and links to each other with internal spline in the hub splines 22.
The front portion of retainer axle 18 is by bearing 10 supportings that are arranged in the front cover 16; The rear portion of retainer axle 18 has the ladder boss, the previous boss 27 of ladder boss is supported by the bearing 28 that is installed in the ring gear 19, be equipped with four uniform planet pins 30 in interval on the ear end face of the boss 29 in back, the circular groove 31 that the center has power supply pivot front end to insert, the front end spindle nose of armature shaft is inserted in this circular groove 31, and by the sliding supported condition in this circular groove 31, be separately installed with planetary pinion 32 on four planet pins 30, the armature shaft front portion is connected with shaftgear 33, this shaftgear 33 is meshed with four planetary pinions 32 respectively, four planetary pinions 32 are meshed with ring gear 19, thereby the moment of torsion of armature shaft is delivered to retainer axle 18, one end of shift fork 15 is connected with movable core 11 tail ends, and the other end of shift fork 15 and sleeve 21 are hinged.
The equal turn numbers of pull in winding 12, hold-in winding 13, the head end of these two coils links together, common termial 20 is externally drawn, the tail end of pull in winding 12 is connected with wiring terminal 20, wiring terminal 20 is power ends of direct current motor 2, also be the main contact of magnetic switch 1, the tail end bonding of hold-in winding 13.
Please refer to Fig. 1, Fig. 6, working principle of the present utility model is as follows: after key operation was connected, the pull in winding 12 of magnetic switch, the current loop of hold-in winding 13 were connected simultaneously.
Current loop by pull in winding is: battery positive voltage → magnetic switch wiring terminal → pull in winding → armature → battery terminal negative.
Current loop by hold-in winding is: battery positive voltage → magnetic switch wiring terminal → hold-in winding → battery terminal negative.
So under the acting in conjunction of pull in winding 12 and hold-in winding 13, movable core 11 is inhaled into, by shift fork 15 overrunning clutch 17 is released, make the engagement of actuation gear and engine flywheel ring gear, movable touching plate 14 is connected with the stationary contact of wiring terminal 20, so the big electric current of storage battery is through armature winding, make armature produce powerful torque, the armature high speed rotating, behind planetary gear speed-reduction, pass to retainer axle 18, external splines 26 on the middle part axostylus axostyle of retainer axle 18 is made of unidirectional helical teeth, and when 18 rotations of retainer axle, this external splines 26 is rotation thereupon also, drive hub splines 22 rotations, pass to actuation gear 23 by overrunning clutch 17 again,, make engine start after actuation gear 23 drives the running of engine flywheel ring gear.
And this moment, pull in winding 12 is by short circuit, and the engaging position of actuation gear 23 is kept by the electromagnetic attraction of hold-in winding 13.After motor is started, disconnect the moment of key operation, the electric current of supplying with pull in winding 12 and hold-in winding 13 is cut off, and this moment, movable touching plate 14 still was in closed state with the stationary contact of wiring terminal 20, and the electric current in the hold-in winding 13 can only form loops through pull in winding 12.This moment, pull in winding 12 was identical with size of current in the hold-in winding 13, but direction is opposite, and the current direction in the hold-in winding 13 is constant.Because pull in winding 12 is identical with the number of turn of hold-in winding 13, current opposite in direction, thereby magnetic flux is offset fully.Under the effect of Returnning spring 9, movable core 11 repositions, the actuation gear 23 on the overrunning clutch 17 tooth axles withdraws from engagement, and movable touching plate 14 disengages with the stationary contact of wiring terminal 20, cuts off starter circuit capable, and starter motor shuts down.
