TWO STAGE STARTER DRIVE SYSTEM

A two stage positive shift starter drive system for an internal combustion engine is disclosed. A pair of electrical switches are sequentially actuated by an actuator solenoid engaging the starter drive's pinion gear with the engine's ring gear. The first switch actuated after a predetermined displacement of the solenoid's armature applies electrical power to the cranking motor's through a resistance connected in series with the cranking motor and connected in parallel with the solenoid's pull in coil. The resistance reduces the electrical power applied to the cranking motor and the potential across the solenoids pull-in coil thereby reducing the rotational speed and the engagement force applied to the pinion gear. The end of the armature travel closes the second switch applying full power to the cranking motor permitting normal cranking of the engine with the pinion gear fully engaged with the ring gear.

Starter for engines and its starting circuit

STARTER WITH INTERMEDIATE GEAR

PROBLEM TO BE SOLVED: To provide a starter with an intermediate gear capable of thinning a mooring member by reducing bending moment acting on the mooring member 9. SOLUTION: In the starter with the intermediate gear, the outermost diameter of a ring gear side wall part 28 opposing to a ring gear side end surface of the mooring member 9 and the outermost diameter of a clutch opposing to an anti-ring gear side end surface of the mooring member 9 overlap in a radial direction. Consequently, impact acting on the mooring member 9 from the ring gear side wall part 28 can be born by the clutch 5 concentrically in an opposite direction to a direction in which the impact acts when the impact generated at a time of meshing of the intermediate gear 8 and the ring gear acts on the mooring member 9, and inclination of the mooring member 9 is inhibited. As a result, bending moment acting in the mooring member 9 can be reduced as compared to a case that the outermost diameter of the ring gear side wall ...

... 29,814. Bendix, V. Dec. 30,1912, [Convention date]. Turning-gear.-An electric motor 3 turns the engine fly-wheel 2 through a spur pinion or worm 6 mounted on a screwed extension 5 of the armature shaft. The worm 6 is normally held in the disengaged position by a spring catch 19 engaging .with a plate 15, which is gripped between collars on the worm. When the motor starts to turn, the inertia of the worm and the friction between the plate and collars prevent rotation of the worm, which then moves endways on the screw into gear with the fly-wheel. When the engine speeds up, the worm is thrown out of engagement by screwing back on the armature-shaft extension. The circuit from the battery to the electric motor is first closed by a push-button 11 and is held closed by a switch 18 carried by the plate 15. The switch 18 is opened when the wheel is disengaged.

PINION GEAR AND STARTER WITH PINION GEAR

To suppress generation of noise during cranking, a pinion gear is fixed to a drive shaft of a starter starting an internal combustion engine. The pinion gear rotates a ring gear provided to the internal combustion engine by meshing therewith. The pinion gear includes gear teeth and an annular hollow portion located radially inside of the gear teeth. The annular hollow portion accommodates a vibration absorber to absorb vibration generated in the gear tooth.

Engine starting system

A silent start that does not require complicated electrical control and does not hinder downsizing of an engine, and a quick start that does not increase energy consumption can be realized. To accomplish this, in an engine starting system for rotating a crankshaft by meshing an idle gear (17) driven by a pinion (16) of a starter motor with a ring gear (5) of the crankshaft, the idle gear (17) is provided to be movable with respect to the ring gear (5) in a radial direction (V, W) of the ring gear (5). The idle gear (17) is moved by an actuator from outside the ring gear (5) in the radial direction (V), so that the idle gear (17) meshes with the ring gear (5). Tooth collision occurs at a lower probability than in a conventional case wherein the pinion is moved in the axial direction and is meshed with the ring gear. The impact of collision decreases, so that collision noise decreases. Complicated electrical control of the starter motor (11) is not needed.

The starter (1) has a system of pushing the pinion gear (7) in the direction of the anti-motor side by using the attracting power of the electromagnetic switch (10) via the shift lever (9). The switch coil (16) of the electromagnetic switch (10) is constituted of one coil that is electrically separated from the motor circuit. The mass of pinion gear 7 is set to 100g or less, the switch extrusion power stored in the drive spring (21) is set to 70N (Newton) or less, and the operation current of the electromagnetic switch (10) is set to 12 amperes or less. With this starter (1), since the switch coil (16) and the motor circuit can be electrically separated, the terminal for connection for connecting the conventional attracting coil and conventional "M terminal bolt" can be abolished. Further, by setting the operation current of the electromagnetic switch 10 to 12 amperes or less, it is possible to control the operation current directly by the ECU.

For the starter of engine

本发明涉及一种用于引擎的启动器。启动器具有通过使用电磁开关的吸引力经由变速杆沿反电机侧的方向推动主动齿轮的系统。电磁开关的开关线圈由与电机电路电分离的一个线圈构成。主动齿轮的质量设置为100g或更小，驱动弹簧中存储的开关推压力被设置为70N(牛顿)或更小，并且电磁开关的工作电流被设置为12安培或更小。在该启动器中，因为开关线圈和电机电路可以电气分离，所以可以去除用于连接传统的吸引线圈和传统的“M端螺栓”的用于连接的端子。此外，通过将电磁开关的工作电流设置为12安培或更小，可以直接由ECU控制工作电流。
