Abstract
A magneto for a motor vehicle includes a flywheel having an exciting source and adapted to rotate in timed relation to the engine, and an armature to be excited by the exciting source. It also comprises an elastic steel cover on at least the inner surfaces of its magnet elements, so that the elements are pressed against, and positioned with respect to, the inner surface of the rim of tray-shaped flywheel.
Claims15
In a magneto for a motor vehicle including a flywheel adapted to be driven in timed relation to the engine and a set of magnet elements secured as an excitation source to the inner peripheral surface of the rim of said flywheel, the improvement comprising a ring-shaped magnet element holder of spring steel capable of expanding outwardly and fitted to the inner peripheral surfaces of said magnet elements and secured altogether to said inner peripheral surface of said flywheel rim with adhesive.
In a magneto for a motor vehicle including a flywheel adapted to be driven in timed relation to the engine and a set of magnet elements secured as an excitation source to the inner peripheral surface of the rim of said flywheel so that the magneto generates energy output with the running of the engine, the improvement comprising a first and a second side rings of nonmagnetic material covering the both sides of said magnet elements, and a magnet element holder of spring steel capable of expanding outwardly and fitted to the inner peripheral surfaces of said magnet elements and secured altogether to said inner peripheral surface of said flywheel rim with adhesive.
In a magneto for a motor vehicle including a flywheel adapted to be driven in timed relation to the engine and a set of magnet elements secured as an excitation source to the inner peripheral surface of the rim of said flywheel, the improvement comprising elastic means of spring steel contacting at least the inner peripheral surfaces of said magnet elements for biasing said magnet elements outwardly towards the inner peripheral surface of said flywheel rim.
