tooth.In engagement process, if the driven steering gear of the engaging tooth of actuation gear and engine flywheel ring tooth pushes up mutually since this moment actuation gear towards the opposite spin that drives engine flywheel ring tooth spiral and turn, so meshing of can taking advantage of a situation.If the engaging tooth of actuation gear pushes up mutually with the driven opposite direction tooth of engine flywheel ring tooth, 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, the namely moving motion feeding counter-rotating of parallel circle hook of this engagement system engagement of taking advantage of a situation, and this engagement system meshes quite smooth and easy and should not produce the apical tooth fault.Eccentric unidirectional drive central siphon rotarily drive the piece of only

drive tester in power-down state stops operating.Movable core under the effect of return spring in the returning position spiral 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 and friction steel disc frictional force disappear, the precession lock-up clutch is removed locking, and movable core returning position under the effect of return spring promotes the axial front slide of spiral drive.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 spiral drive main shaft, 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 and clump driving gear are done the moving motion of reciprocal parallel circle hook, and the actuation gear moving motion of parallel circle hook in the other direction makes actuation gear separate very 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 smoothly with flywheel ring tooth, the tooth fault can not occur stinging in which kind of situation.The eccentric unidirectional drive central siphon opposite spin piece of only advancing and retreat is got back to the retaining point, eccentric unidirectional drive central siphon, precession spreadet spreadet wheel, precession clump gear, and the precession master gear stops opposite spin, and the spiral drive axle also stops advancing slip, and engine start is complete.
The beneficial effects of the utility model are:
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 is difficult for producing apical tooth and stings the tooth fault.Revolve engagement along the actuation gear of engagement type retarding starter and engine flywheel ring tooth and be the moving motion feeding counter-rotating of the actuation gear parallel circle hook 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 sliding the separation along live axle helical spline vertical spin.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 produces extremely easily apical tooth and stings the tooth fault.
