Claims

[Scope of utility model registration request]

Ring gear, sun gear that rotates coaxially with the ring gear,
A planetary gear mechanism includes a carrier that rotatably supports a ring gear and a planetary gear that meshes with one gear and rotates coaxially with the ring gear, an engine crankshaft that drives and rotates either the ring gear or the sun gear, and an output from the carrier. A coupling means capable of coupling any two elements of the ring gear, sun gear, and carrier to an engine auxiliary machine that is driven and rotated by the engine; a one-way crankshaft that only allows rotation in the same direction as the shaft and prevents rotation in the opposite direction, and when the number of revolutions of the crankshaft is below a predetermined value, the two elements are coupled by a coupling means, and the one The number of rotations of the crankshaft is transmitted to the carrier without changing the rotation speed of the crankshaft, and when the number of rotations of the crankshaft exceeds a predetermined value, the connection of the two elements is released by the coupling means, and the one-way clutch is used to reverse the rotation speed of the crankshaft. By blocking rotation in the direction, the rotational speed of the one is reduced and transmitted to the carrier;
In such a variable speed accessory drive device, the two elements are interposed between the two elements, and only when one end is always fixed to one of the two elements and the other end remains and is engaged with the other. and a coil that is provided on the other side of the two elements and causes the other end of the spring cooler latch to engage the other end of the spring cooler by its electromagnetic force, When the rotational speed of the crankshaft is below a predetermined value, the coil is energized and the other end of the spring clutch is engaged with the other end of the spring clutch, and when the rotational speed of the crankshaft exceeds a predetermined value, the coil is excited. A variable speed auxiliary drive device, characterized in that the engagement is released by putting the auxiliary gear into a de-energized state.
