The pull in winding of magnetic switch and the head end of Bao Weixianquan all are electrically connected with the starter motor wiring terminal; The end of pull in winding is electrically connected with B starter switch wiring terminal, protects shell electrical connection the carry out bonding of bit line circle end with magnetic switch.The B starter switch wiring terminal of magnetic switch is electrically connected through the power-line terminal of connecting sheet with direct current motor.The A starter switch wiring terminal of magnetic switch connects with the storage battery positive electrical through the starting lead, and the starter motor wiring terminal of magnetic switch is electrically connected through the start gear of lead with ignition switch.Revolve along engagement type retarding starter working procedure following: ignition switch is connected start gear; The starter motor wiring terminal energising of magnetic switch; Pull in winding and Bao Weixianquan have electric current through producing electromagnetic attraction; Movable core overcomes the elastic force of return spring and is inhaled under two coil electromagnetism suction actings in conjunction; So the chute that the precession drive main spindle of drive precession live axle and the conrotatory of precession driving countershaft are advanced on the locking body frame slides backward; The precession master gear rotation of sliding and drive the band internal thread spline in the helical spline part back of precession drive main spindle front end; The rotation of precession master gear drives with the precession clump gear of its engagement with the coaxial precession spreadet spreadet wheel of fixing of precession clump gear also and then rotation, and the rotation of precession spreadet spreadet wheel drives also rotates through the eccentric unidirectional drive central siphon of the precession locking tooth on the eccentric central siphon with its engagement, and eccentric unidirectional drive central siphon rotation drives actuation gear and carries out circular arc turn campaign with the clump driving gear along eccentric circle track; Actuation gear circular arc turn campaign can be carried out feeding and engagement with engine flywheel ring tooth, and the direction of actuation gear rotation was identical when actuation gear circular arc turn travel direction was piloted engine together.Clump driving gear circular arc turn campaign is to carry out in main transmission internal gear inboard; Because the main transmission internal gear also rotates when circular arc turn campaign with the effect clump driving gear of clump driving gear engagement; The direction of its rotation is opposite with circular arc turn moving direction; Clump driving gear rotation drives the driving auxiliary axle and also rotates with dynamic zigzag fashion ratchet, and this moment, dynamically the direction of zigzag fashion ratchet rotation was its direction of skidding with static zigzag fashion ratchet, but when not having external force to act on to be fixed in the actuation gear with the drive main spindle front end of static zigzag fashion ratchet; Under the effect of return spring elastic force; Dynamically the zigzag fashion ratchet is non-slip, drives the drive main spindle rotation with static zigzag fashion ratchet, and actuation gear is towards the direction rotation of circular arc turn reverse movement.Actuation gear is that one of them teeth of the several teeth of actuation gear engages between a plurality of teeth of engine flywheel ring tooth two teeth wherein with the engagement of engine flywheel ring tooth; One of them tooth of this of actuation gear and title engaging tooth; One in two teeth of that of engine flywheel ring tooth are to drive engine flywheel ring tooth spiral veer and claim that by the driving direction tooth another is to drive engine flywheel ring tooth spiral at the actuation gear engaging tooth to change opposite direction and claim to be driven tooth in the other direction at the actuation gear engaging tooth.In engagement process, if being pushed up mutually of the engaging tooth of actuation gear and engine flywheel ring tooth by the driving direction tooth since this moment actuation gear towards driving the opposite spin that engine flywheel ring tooth spiral changes, so meshing of can taking advantage of a situation.If the engaging tooth of actuation gear pushes up with the opposite direction tooth that driven of engine flywheel ring tooth mutually; This external force can make dynamic zigzag fashion ratchet overcome the return spring elastic smooth and drive helical spline spiral slide on the countershaft and move back and skid; The actuation gear that is fixed in the drive main spindle front end of static zigzag fashion ratchet also skids, so meshing of also can taking advantage of a situation.Actuation gear is parallel with engine flywheel ring tooth, this engagement system moving motion feeding counter-rotating of the parallel circle hook just engagement of taking advantage of a situation, and this engagement system meshes quite smooth and easy and should not produce the apical tooth fault.The rotation of eccentric unidirectional drive central siphon drive the piece of only advancing and retreat that also drives when actuation gear meshes with engine flywheel ring tooth on its eccentric central siphon by the stopping point in the groove of only advancing and retreat of precession locking body frame to ending an into motion; Also accomplished engagement when moving to when ending into some actuation gear and engine flywheel ring tooth; Eccentric unidirectional drive central siphon stops the rotation; Precession spreadet spreadet wheel, precession clump gear, precession master gear all stop the rotation; The precession drive main spindle of precession live axle is sliding no longer backward; The precession driving countershaft of the precession of the movable core of electro-magnet switch drive at this moment live axle overcomes return spring elastic force and slides backward; Cunning is stirred clutch and is dialled the gland that briquetting pushes the precession lock-up clutch forward behind the precession driving countershaft; Gland overcomes return spring elastic force and travels forward that to press against the frictional force that generations is very big together motionless with precession locking shaft locking with the friction steel disc with friction plate, and also just also locking is motionless with eccentric unidirectional drive central siphon through being fixed on precession spreadet spreadet wheel on the precession locking shaft, when precession lock-up clutch locking off-centre unidirectional drive central siphon is motionless; The movable core of magnetic switch pushes contact disc with A and the conducting of two starter switch wiring terminals of B; The energising of power supply of dc motor wiring terminal, the direct current motor fast rotational drives the driving countershaft rotation of eccentric unidirectional drive central siphon again through driving mechanism after reducing gear slows down; Drive countershaft and drive drive main spindle and actuation gear rotation with static zigzag fashion ratchet through the dynamic zigzag fashion ratchet that is installed in front end again, the actuation gear rotation drives the engine flywheel rotation and pilots engine.Meanwhile pull in winding is then by short circuit, and movable core leans on the magnetic force of Bao Weixianquan to remain on the attracted position.After the engine start, ignition switch is broken off start gear, the starter motor wiring terminal outage of magnetic switch; The electric current of protecting in the bit line circle constitutes the loop through pull in winding; The flow direction that two coils are produced is cancelled each other on the contrary, and movable core is returning position under the effect of return spring, and contact disc is return also; A, two starter switch wiring terminals of B break off, and the direct current drive tester in power-down state stops operating.Movable core under the effect of return spring in the returning position precession drive countershaft under the effect of its return spring to front slide; Clutch is dialled the gland that briquetting no longer pushes the precession lock-up clutch; Gland is returning position under its return spring effect; Friction plate disappears with friction steel disc frictional force, and the precession lock-up clutch is removed locking, and movable core returning position under the effect of return spring promotes precession driving axial front slide.After the engine start; Flywheel ring cingulum actuation gear and is rotated; Dynamically the zigzag fashion ratchet skids; Outside engine flywheel ring tooth centrifugal force, get rid of under the effect with two kinds of power of the advancing slip promotion of precession drive main spindle; The opposite spin during all towards precession of precession master gear, precession clump gear, precession spreadet spreadet wheel and eccentric unidirectional drive central siphon, actuation gear is done the moving motion of reciprocal parallel circle hook with the clump driving gear, and the actuation gear moving motion of parallel circle hook in the other direction makes actuation gear very separate smoothly with engine flywheel ring tooth.During clump driving gear circular arc turn in the other direction campaign since the effect of meshing with the main transmission internal gear also rotate; Its sense of rotation is identical with the direction of the strong drive actuation gear rotation of engine flywheel ring tooth; And to skid also be that actuation gear skids to dynamic zigzag fashion ratchet when the strong drive actuation gear of engine flywheel ring tooth rotated; Therefore guaranteed that more no matter actuation gear can separate with flywheel ring tooth smoothly, the tooth fault can not occur stinging under which kind of situation.The eccentric unidirectional drive central siphon opposite spin piece of only advancing and retreat is got back to the stopping point, eccentric unidirectional drive central siphon, precession spreadet spreadet wheel, precession clump gear, and the precession master gear stops opposite spin, and the precession live axle also stops advancing slip, and engine start finishes.
The invention has the beneficial effects as follows:
Revolve along the actuation gear of engagement type retarding starter and the engagement of engine flywheel ring tooth with separates extremely smooth and easyly, it has not only alleviated the wearing and tearing of actuation gear and engine flywheel ring tooth, makes it need not frequent replacing, also difficult generation apical tooth and sting the tooth fault.Revolve engagement along the actuation gear of engagement type retarding starter and engine flywheel ring tooth and be actuation gear parallel circle hook and move the motion feeding counter-rotating engagement of taking advantage of a situation; Separation is that movable core returning place force and the engine flywheel ring tooth centrifugal force of magnetic switch gets rid of two kinds of power outward and drives the actuation gears moving motion of parallel circle hooks in the other direction and separate; And actuation gear also rotates identical direction rotation towards the strong drive actuation gear of engine flywheel ring tooth during the actuation gear moving motion of parallel circle hook in the other direction, so and actuation gear when the strong drive of engine flywheel ring tooth is rotated, can skid and guaranteed which kind of situation no matter actuation gear and engine flywheel ring tooth are in and can carry out smooth and easy the separation.The engagement of the actuation gear of the engagement type retarding starter of existing electromagnetism and engine flywheel ring tooth is that engagement force is inserted in actuation gear sliding movement feeding before live axle helical spline vertical spin, and separation is that movable core returning place force and the engine flywheel ring tooth centrifugal force of magnetic switch gets rid of the actuation gear two kinds of power of skidding outward and makes actuation gear return to slide along live axle helical spline vertical spin to separate.The actuation gear of the engagement type retarding starter of electromagnetism has some setbacks with separating all with the engagement of engine flywheel ring tooth, so actuation gear and engine flywheel ring odontotripsis quite seriously need often replacing, and extremely is easy to generate apical tooth and stings the tooth fault.
