Detailed description of the invention
The launcher 1 for internal combustion engine shown in Fig. 1 has starter pinion 2, and this starter pinion 2 is meshed with the ring gear 3 of internal combustion engine, to start internal combustion engine 4. As shown in double-head arrow, starter pinion 2 is axially moveably supported on axle 5, and wherein starter pinion 2 couples in not relatively turnable mode with axle 5. Starter pinion 2 the off-position return and advance and internal combustion engine 4 ring gear 3 the position of engagement between adjusted by starter relay 6, this starter relay 6 is with electromagnetic mode structure and includes relay coil 7 and the displacement armature 8 that can be energized, and this displacement armature 8 is axially drawn in relay coil when being energized to relay coil 7. Displacement armature 8, by being connected with engaging bar 9 and starter pinion 2 kinetics, therefore adds displacement armature 8 in the starter pinion 2 corresponding axially adjustable motion between off-position and the position of engagement in resting position and the axially adjustable motion adjusted between position.
Rotation actuation movement on axle 5 or starter pinion 2 produces by electric activation motor 11, and this starter motor 11 is connected by planetary gear mechanism 12 and axle 5. When handling electric activation motor 11, make axle 5 be in rotation, and therefore also make starter pinion 2 be in rotation.
Launcher 1 has adjustment or control equipment 10, is controlled starter relay 6 and the function of starter motor 11 by this adjustment or control equipment 10.
When carrying out axially adjustable motion at the situation bottom offset armature 8 handling starter relay 6, when arriving adjustment position, coupling, with the kinetics adjusting motion of displacement armature 8, the electric current connected for starter motor 11 by switch element, therefore starter motor 11 is kept in motion and drives axle 5 and starter pinion 2 rotationally.
Launcher 1 is provided with one-way clutch mechanism, and this one-way clutch mechanism is formed as roller one-way clutch 14.Engage bar 9 and act on spring part 13, drivening piece 15 power of roller one-way clutch 14 is axially loaded by this spring part 13, the wherein support collar of roller one-way clutch 14 or the roller axle collar 16 and this drivening piece 15 combined effect, and this support collar 16 constituted with single-piece with starter pinion 2. Roller one-way clutch 14 allows the driving direction along electric activation motor 11 to transmit rotational motion. But, once the velocity of rotation of ring gear 3 is high to making driving direction reverse after internal combustion engine 4 starts, just coupled by the kinetics between roller one-way clutch 14 band of discontinuance moving part 15 and support collar 16.
Illustrating planetary gear mechanism 12 in figs. 2 and 3, the actuation movement of electric activation motor is delivered on starter pinion by this planetary gear mechanism 12.
