20130192419 | ENGINE STARTING DEVICE - An engine starting device includes: a starter motor; a pinion unit coupled to an output-shaft side of the starter motor by a spline, for sliding in an axial direction; and a ring gear which meshes with a pinion gear of the pinion unit pushed out by a push-out mechanism, and receives a transmission of a rotation force of the starter motor, thereby starting an engine. The pinion unit includes, on all teeth on distal end portions in a meshing axial direction of the pinion gear meshing with the ring gear, synchronization surfaces which are a pair of surfaces parallel with the meshing axial direction, and have a thickness thinner than a tooth thickness of the pinion gear. | 08-01-2013 |
20130276578 | ENGINE STARTING DEVICE - The engine starting device includes a starter motor, a pinion portion, a pushing mechanism for pushing a pinion gear of the pinion portion to a position at which the pinion gear comes into meshing engagement with a ring gear, and an integrated switch for operating a motor-energization switch to pull a plunger after the pinion gear is pushed, by configuring a switch for actuating the pushing mechanism and turning ON/OFF an energization current to the starter motor by a single plunger coil. When a restart request is issued after an engine stop is requested and therefore the integrated switch is placed in an ON state, operation timing of the pushing mechanism and coil-operation timing of the plunger coil are set so that the starter motor avoids operating until the pinion gear comes into contact or meshing engagement with the ring gear. | 10-24-2013 |
20140060247 | ENGINE STARTING DEVICE - The engine starting device includes a pinion unit which is spline-coupled to an output shaft side of a starter motor to slide in an axial direction, the pinion unit including a one-way clutch which spins for rotation in the same direction as that of rotation of the engine, and a pushing mechanism for moving the pinion unit to a position in which the pinion unit comes into meshing engagement with a ring gear. A pinion gear of the pinion unit is movable in the axial direction as a single body, and includes a chamfered portion having a curved surface along a tooth surface on a non-torque transmitting surface side and a large length in the axial direction, the chamfered portion being provided to a ring-gear side distal end portion of the tooth surface on the non-torque transmitting surface side. | 03-06-2014 |
