Conical friction ring type continuously variable transmission device

A conical friction ring type continuously variable transmission device comprising:

• first and second conical friction wheels that are disposed on mutually parallel axes inside an oil-tight space and disposed such that a large diameter side and a small diameter side are opposite each other in an axial direction;
• and
• a ring that is provided interposed between opposing inclined surfaces of the first and second friction wheels so as to surround the first conical friction wheel, wherein
• a portion of the ring is submerged in an oil reservoir in a lower portion of the space, power is transmitted by contact between the ring and the first and second conical friction wheels with oil interposed therebetween, and moving the ring in the axial direction steplessly changes a speed,
• the conical friction ring type continuously variable transmission device is mounted in a vehicle, and a rotational direction is set such that, during forward travel of the vehicle, opposing portions of the first and second conical friction wheels move upward from below,
• the axis of the second conical friction wheel is in a horizontal direction and positioned above the axis of the first conical friction wheel, and a lower end of a maximum diameter side of the second conical friction wheel is disposed so as to be positioned above an oil level of the oil reservoir,
• an oil strainer, which filters by allowing oil raked up from the oil reservoir to pass through, is disposed on a side of the second conical friction wheel opposite the axis of the first conical friction wheel with respect to the axis of the second conical friction wheel, and
• a guide member that guides oil raked up by the ring toward the oil strainer is disposed on at least an upper portion of the second conical friction wheel.
