20080223156 | Startup Torque Transmitting Mechanism of an Internal Combustion Engine - An outer race support plate to which torque of a pinion gear is transmitted from a ring gear via a one-way clutch and thus rotates a crankshaft is provided separately from a flywheel and is mounted to the crankshaft not via the flywheel. As a result, impact noise produced when the one-way clutch engages is not directly transmitted to the flywheel. Accordingly, noise radiation from the flywheel can be suppressed, thereby enabling noise to be reduced. | 09-18-2008 |
20080276735 | STARTER DEVICE FOR A MOTOR DRIVEN MACHINE - The invention pertains to a device for starting an internal combustion engine for handheld equipment such as chain saws, lawn mowers, lawn trimmers and the like, or for vehicles such as mopeds, boats or miniature aircraft. The starting device features an output element into which a starter torque can be introduced when the starting device is actuated. The output element is functionally connected to a crankshaft of the internal combustion engine in order to introduce a crankshaft torque therein. The functional connection between the output element and the crankshaft introduces variable crankshaft torque into the crankshaft depending on the rotational angle of the crankshaft at a constant starter torque. This advantageously improves force or torque characteristics for largely operating the starter device independently of the compression phase and the expansion phase of the internal combustion engine. | 11-13-2008 |
