Abstract: Upon gear disengagement, a pinion gear drive means actuates a pinion gear to disengage from a ring gear while the starter motor of a starting device is rotated or while injectors of an engine are caused to inject fuel into cylinders of the engine to ignite an air-fuel mixture therein, thereby releasing the gear disengagement. Applied to an idling stop-capable vehicle that engages the starter pinion gear with the engine ring gear beforehand to shorten the time to restart, the inventive control apparatus with the above feature releases unfailingly the engagement against metal-to-metal frictional force that causes the gears to be stuck with each other upon engine stop.

Abstract: There is provided an idle stop system that can more quickly restart with small noise in conducting idle stop. In preparation for a restart request during an engine inertial rotation, after a motor is rotated in a state where a starter motor is not coupled to the engine, a pinion is engaged with a ring gear during the motor is subjected to inertial rotation like the engine. In this situation, the rotational speed including future pulsation of the engine is estimated with the use of information on the crank angle, and a pinion pushing timing is controlled so that the pinion and the ring gear contact each other with a given rotational speed difference taking a delay time of a pinion pushing unit into consideration.

Patent number: 8567364
Abstract: A starter for an engine is equipped with a planetary gear speed reducer, a restraining mechanism, and a shock absorber which is made up of a rotary disc, a stationary disc, a case, and a load applying mechanism. The load applying mechanism applies a load to the stationary and rotary discs to develop a given degree of friction therebetween. When an excessive torque acts on the rotary disc through the internal gear, the shock absorber induces the rotary disc to rotate against the given degree of friction to absorb the torque to eliminate a physical impact to be exerted on the planetary gear speed reducer. The restraining mechanism restrains the load applying mechanism from moving in a radius direction of the internal thread to avoid undesirable engagement of the load applying mechanism with the internal thread, thereby ensuring the stability in applying the load to the stationary and rotary discs.

Patent number: 8413628
Abstract: A ring gear is formed by joining a race side-region formed body, a gear side-region formed body and an intermediate region formed body. Accordingly, it is possible to perform processing of an inner race portion of the race side-region formed body with none of the gear side-region formed body and the intermediate region formed body present. By causing the gear side-region formed body and the intermediate region formed body to absorb changes in design depending on the type of internal combustion engine, it is possible to standardize the size and the shape of the race side-region formed body for various engine types. Because the inner race portion, as well as a disposition surface and a contact surface for the seal rings are formed on the same race side-region formed body, it is possible to finish the surfaces with precise positional relationship.

Patent number: 8408175
Abstract: A starter system is provided for an engine having a stop-start capability. The starter system includes a first gear coupled to the engine, wherein the first gear rotates at a speed of the engine. The starter system also includes a starter arranged relative to the engine. The starter includes a second gear arranged to selectively mesh with and apply torque to the first gear in order to start the engine, such that the second gear is capable of rotating at the speed of the engine. The starter additionally includes a synchronizer arranged to substantially match the speed of the first gear with the speed of the engine prior to engagement of the first and second gears, such that the second gear is enabled to mesh with and apply torque to the first gear to thereby start the engine. The starter system and the engine may be employed in a vehicle.

Patent number: 8371259
Abstract: A starter for starting an internal combustion engine has an electric starter motor, which has a drive shaft provided with an external toothing, a pinion shaft bearing a pinion, and a clutch element of a roller-type overrunning clutch situated between the drive shaft and the pinion shaft. The clutch element has an internal toothing mating with the external toothing of the drive shaft and is shiftable together with the pinion shaft away from the starter motor in the axial direction of the drive shaft into a meshing position in which the pinion mates with a gear wheel or ring gear of the internal combustion engine. The starter also has a device provided for directly supporting the pinion shaft on a section of the external toothing of the drive shaft facing away from the starter motor.

Patent number: 8356584
Abstract: An engine is disclosed having a flywheel arrangement comprising a starter motor (1) having a pinion gear (2) at an output shaft. The pinion gear (2) constantly engages a corresponding crank gear of a crank wheel (3) located between an engine block and a flywheel assembly (9) of the engine. The crank wheel (3) is operatively connected to a crankshaft (4) of the engine via a one-way clutch unit (5). The flywheel assembly (9) comprises a first flywheel body (6) connected to the crankshaft (4) of the engine. A second flywheel body (7) is rotatable relative to the first flywheel body (6) and coupled thereto such that is able to move elastically through a limited angular distance relative to the first flywheel body (6). An interlocking device includes at least one locking arrangement (8) and is adapted to produce an interlocking connection between the second flywheel body (7) and the first flywheel body (6) during cranking of the internal combustion engine.

Abstract: A Belt Driven Electric Starter System (BES) may have an idle pulley is composed of pivot point idle pulley forming pivot points at both sides of driving belt, which is wound on starter generator pulley and crank pulley, and driven idle pulley forming the fixing point, and a side of tension controller is fixed to engine and the opposite side is fixed to starter generator combined with starter generator pulley, such that it is possible to more effectively use the empty space without interference with the other portions in the entire layout of the BES. Further, excessive tension of driving belt due to starter generator when the engine is started can be attenuated by retraction of tension controller that moves with starter generator, while the excessive tension of driving belt due to crank pulley when electricity is generated can also be attenuated by extension of tension controller that moves with starter generator.

Patent number: 8290693
Abstract: An internal-combustion-engine automatic stop and restart system performs restarting control by making the pinion pushing unit push out the pinion gear so as to engage with the ring gear, when the restarting condition is satisfied in a time period from a time when the automatic stopping condition is satisfied to a time when the rotation of the internal combustion engine stops. A throttle valve control unit opens the throttle valve even when the restarting condition has not been satisfied and stops control of the throttle valve in a time period from when the rotation of the internal combustion engine stops to when the restarting condition is satisfied, when the rotation speed of the internal combustion engine becomes lower than a predetermined value in a time period from when the automatic stopping condition is satisfied to when the rotation of the internal combustion engine stops.
