The working procedure of starter motor of the present invention is: with first embodiment is example, when motor in when operation, ignition switch (25) is in ON position (as shown in Figure 7), main circuit this moment (27) is connected, starter motor engagement circuit (28) disconnects with firing circuit (21), defective starter motor, actuation gear (3) breaks away from engine start gear ring (19), brake spring (6) and friction spring (5) all are compressed, brake disc (14) rubbing surface and keep plate (16) rubbing surface are fitted under brake spring (6) pressure effect, control pull rod (7) is connected two normally-closed contacts of limit switch (9), and normally opened contact disconnects.When parking of automobile is flame-out, ignition switch (25) forwards the OFF position to from ON, know from circuit diagram and ignition switch (25) structural drawing, connect at this position power line contact A (34) and copper sheet 1 (36), two normally-closed contacts of limit switch (9) also are in on-state simultaneously, so whole starter motor engagement circuit (28) is connected, because current-limiting resistance (22) or voltage stabilizer effect in the engagement circuit, starter motor is by very little electric current, the frictional force that the moment of torsion that starter motor produces can overcome between brake disc (14) and keep plate (16) makes slowly rotation of armature shaft (1), brake disc (14) is rotation thereupon also, owing between brake spring (6) and the brake disc (14) thrust-bearing (17) is housed, brake disc (14) almost can not transmit frictional force and give actuation gear (3), the frictional force action that actuation gear (3) is subjected to armature shaft screwed grooves has the trend of rotating with armature shaft (1), but, friction spring (5) one ends drive on the end cap base plate (8) because being fixed on, friction plate (18) is housed between the other end and the actuation gear (3), friction spring (5) produces bigger surface friction drag to actuation gear (3), actuation gear (3) can not be rotated with armature shaft (1), so under the effect of armature shaft screwed grooves, actuation gear (3) will move axially and starting gear ring (19) engagement along armature shaft (1).In actuation gear (3) moving process owing to be subjected to the effect of brake spring (6) and friction spring (5) pressure, make the actuation gear spiral chute be attached to a side of armature shaft screwed grooves, when apical tooth takes place with engine start gear ring (19) in actuation gear (3), actuation gear (3) is no longer mobile, continuation rotation along with armature shaft (1), behind the gap of eliminating between actuation gear spiral chute and the armature shaft screwed grooves, the armature shaft screwed grooves opposite side will contact with actuation gear spiral chute opposite side, as shown in figure 11, and to actuation gear (3) generation moment of torsion, rotation along with armature shaft (1), armature shaft (1) constantly increases the moment of torsion that actuation gear (3) produces, and finally overcome friction spring (5) and starting gear ring (19) end face and actuation gear (3) is rotated with armature shaft (1) the frictional force of actuation gear (3), after eliminating apical tooth, under the effect of brake spring (6) and friction spring (5) power, actuation gear (3) will continue to move the gap of eliminating between two spiral chutes to starting gear ring (19), make the actuation gear spiral chute be affixed to a side of armature shaft screwed grooves once more, as shown in figure 12, so actuation gear (3) just enters engagement with starting gear ring (19).Continuation rotation along with armature shaft (1), actuation gear (3) constantly increases with the mate of starting gear ring (19), friction spring (5) and brake spring (6) disengage with actuation gear (3), frictional force disappears between brake disc (14) and the keep plate (16), actuation gear (3) no longer is subjected to the frictional force of friction spring (5), but actuation gear this moment (3) is subjected to the resistance of starting gear ring (19), continuation rotation along with armature shaft (1), actuation gear (3) will continue to move axially until positioning retainer ring (20) position along armature shaft (1), and actuation gear (3) meshes fully with starting gear ring (19).Actuation gear (3) along armature shaft (1) in the process that moves, the shift fork (4) that is contained in actuation gear (3) annular groove will move with actuation gear (3), shift fork (4) drive control pull rod (7) moves simultaneously, control pull rod (7) the other end drives the push rod (30) of limit switch, mesh fully or the approaching disconnection of bit switch push rod gear-meshing time limit (30) fully normally-closed contact at actuation gear (3) and starting gear ring (19), connect normally opened contact simultaneously, so, because the normally-closed contact of limit switch (9) disconnects, the engagement circuit disconnects, starter motor stops operating, and actuation gear (3) is finished engagement with starting gear ring (19), sends out for the motivation starting and gets ready.When piloting engine, ignition switch (25) forwards the STA position to from OFF, know from circuit diagram and ignition switch (25) structural drawing, connect at this position power line contact A (34) and copper sheet 2 (40), also on of normally opened contact by above-mentioned known limit switch (9), so whole firing circuit (21) is connected, effect closing relay two movable contacts by starter relay (23), starter circuit capable (24) and power connection, starter motor produces than high pulling torque by bigger electric current, can not move vertically again owing to be subjected to the actuation gear (3) that stops of positioning retainer ring (20), make engine start so will rotate with armature shaft (1).Rotating speed raises rapidly after the engine start, when starting gear ring (19) rotating speed during greater than actuation gear (3) rotating speed, starting gear ring (19) will drive actuation gear (3) rotation, the rotating speed of actuation gear (3) will be greater than the rotating speed of armature shaft (1), so will moving along armature shaft (1), actuation gear under the effect of armature shaft screwed grooves (3) make actuation gear (3) and starting gear ring (19) withdraw from engagement in the other direction, while control pull rod (7) also moves and drives limit switch push rod (30) and moves with actuation gear (3), push rod (30) will disconnect the normally opened contact of limit switch (9) and connect normally-closed contact, so firing circuit (21) disconnects, starter relay (23) two movable contacts disconnect, starter motor no longer includes electric current to be passed through, actuation gear (3) also compresses friction spring (5) and brake spring (6) again simultaneously, brake disc (14) is subjected to brake spring (6) pressure effect makes brake disc (14) rubbing surface and the applying of keep plate (16) rubbing surface produce frictional force, starter motor is stopped operating rapidly, avoid actuation gear (3) and the engagement once more of starting gear ring (19) and the wearing and tearing of part.
When vehicle is in operation the motor accident extinguishing, when lighting a fire once more, directly forward ignition switch (25) to the accident extinguishing starting position from the ON position, know from circuit diagram and ignition switch (25) structural drawing, owing to connect at this position power line contact A (34) and copper sheet 1 (36), the normally-closed contact of limit switch (9) is in on-state simultaneously, so at first meshing circuit (28) connects, after actuation gear (3) and starting gear ring (19) are finished engagement, the normally opened contact of limit switch (9) is connected, so firing circuit (21) conducting can be piloted engine smoothly by starter relay (23), and needn't be disconnected vehicle power supply.
