Abstract: A starter for cranking an internal combustion engine is composed of an electric motor, an output shaft driven by the motor, a pinion gear coupled to the output shaft, and a magnetic switch. Electric power is supplied to the motor from an on-board battery through a switch, a movable contact of which is driven by the magnetic switch. The movable contact is connected to a brush lead wire via a connection formed by soft-soldering. The connection formed by the soft-soldering is positioned close to the commutator and covered with an end cover, so that the temperature of the connection becomes higher than other places in the starter. The connection easily melts away to thereby shut off power supply to the motor when its temperature becomes unusually high, and thereby the starter is protected from overheating.

The absorber includes a friction plate which is disposed between a clutch outer and a carrier plate of the overrunning clutch and urged elastically into frictional abutment with the carrier plate. This structure eliminates the need for installing the friction plate on an internal gear of the planetary gear train, thus permitting the internal gear to be reduced in size.

Abstract: A starting apparatus for starting an engine has a drive motor and a reduction gear. The reduction gear includes a shock absorbing member and restricting members. The shock absorbing member is provided to elastically receive a reaction force exerted to an internal gear. The restricting members are provided to restrict a compressed amount of the shock absorbing member by making contact with each other. When bringing into contact with each other, the restricting members make contact at the outside diameter portions thereof. Accordingly, unpleasant noise generated during the operation of the starting apparatus is reduced by the shock absorbing member. Further, the damage to respective parts is reduced.

Abstract: A pinion gear of a starter is engaged with a ring gear of an internal combustion engine by restricting rotation of the pinion gear while driving a motor at a low speed. After the engagement is established, the motor is driven at a full speed by supplying a full current, thereby cranking up the engine. A crank bar for transferring movement of a plunger in a magnetic switch to a pinion-rotation-restricting member is divided into two or three portions. After the divided portions are assembled to the starter, they are connected together to form a solid piece. In this manner, a process of assembling the crank bar into the starter is simplified.

Abstract: An engine starter includes a starter switch having a plunger assembly movable between non-operating operating positions. When the plunger assembly is at the non-operating position, a gap between main stationary and movable contacts is smaller than the sum of a gap between a pinion and an engine ring gear and the most-widely opened variable gap, which is defined between a drive mechanism and a moving shaft. The arrangement is such that, as the plunger assembly moves from the non-operating position to the operating position, the auxiliary contact is first closed to cause the starter motor to be driven at the first speed, and then the main contact is closed to cause the starter motor to be driven at the second speed.

Abstract: A method and apparatus for achieving reliability in starting V-Twin chain or belt-driven motorcycle engines using a conventional motorcycle battery and specially modified automotive cranking motor. The apparatus in its preferred embodiment utilizes a direct drive cranking motor configuration employing a cammed bearing clutch which is placed onto the engine's crankshaft along with a ring gear. The ring gear engages the geared shaft of the cranking motor directly, thereby bypassing the chain or belt-drive and thus effectively removing the main drive chain or belt from the cranking system. The gear ratio between the cranking motor and the ring gear may thus be selected to be optimum for the cranking motor so that the battery and cranking motor may be operated at near optimum power capabilities simultaneously.

Abstract: Systems, methods, and apparatus, consistent with principles of the present invention, allow an unmodified device, for example, a dc starter motor, that normally operates at a first voltage to function in an electrical system providing a second voltage, which is different from the first voltage, and received from the power source. A device actuator, such as a solenoid, is controlled using the second voltage. The first voltage is produced and supplied to the device in response to a first action of the actuator, for example, upon solenoid depression. This voltage is then inhibited from being provided to the device in response to a second action of the actuator, for example, upon solenoid retraction after engine cranking.

A rotor of a generator is connected to the other end of the crankshaft.

Abstract: Engine starting performance is enhanced by a brushless motor having no rotor position detecting sensor. In the first place an engine is rotated forward and then is reversely rotated to overcome a high load region of the engine. Then, the engine is accelerated and rotated forward and started. In a light load region of the engine, the engine is immediately accelerated and normally rotated. It is judged whether the region of the engine is the high load region or light load region based on the rotation speed when the starting operation is started. After the starting operation is started, if the forward rotation speed reaches a first speed, and a second speed which is higher than the first speed is obtained even after predetermined time is elapsed, an immediate starting-judging section 36 outputs a detection signal to a starting/normal rotation control section 37.

Abstract: A remote starting device intended chiefly for use in cars that utilizes a pulse signal that is generated by either an RF transmitter, a keypad, or a telephone. The pulse signal is transmitted to a rotating drive attached to the subject ignition. When the device receives the pulse signal, the rotating drive rotates to activate the ignition of the car, thereby starting the engine. The remote starting device operates independently of the car's circuitry using only the car's battery, via the cigarette lighter, as a power source. There is no need to modify the car's electrical system to install the device. This greatly simplifies installation of the device and does not jeopardize any applicable warranty on the car.
