Abstract
A continuously variable transmission system comprising an input and output rotational member each with a first circular end and a second circular end is disclosed. The output rotational member is located such that the second circular input member end faces the first output member end and the input and output rotational members share a tangential plane. A first and second idler wheel, attached to an idler shaft, contact the input and output rotational members. The first and second idler wheels and idler shaft are configured to translate rotation from the input rotational member to the output rotational member.

A continuously variable transmission system comprising:
- an input rotational member comprising a first circular input member end and a second circular input member end;
- an output rotational member comprising a first circular output member end and a second circular output member end, wherein the output rotational member is located such that the second input member end faces the first output member end, the first circular input member end, second circular input member end, first circular output member end and second circular output member end sharing a tangential plane;
- an idler shaft comprising a first shaft end and a second shaft end;
- a first idler wheel located on the idler shaft at the first shaft end, and in contact with the input rotational member;
- and
- a second idler wheel located on the idler shaft at the second shaft end, and in contact with the output rotational member and wherein the idler shaft and first and second idler wheels are configured to translate rotation of the input rotational member to the output rotational member.
A continuously variable transmission system comprising:
- an input rotational member comprising a first circular input member end and a second circular input member end;
- an output rotational member comprising a first circular output member end and a second circular output member end, wherein the output rotational member is located such that the second input member end faces the first output member end and the input and output rotational members share a tangential plane;
- an idler shaft comprising a first shaft end and a second shaft end:
- a first idler wheel located on the idler shaft at the first shaft end, and in contact with the input rotational member:
- a second idler wheel located on the idler shaft at the second shaft end, and in contact with the output rotational member and wherein the idler shaft and first and second idler wheels are configured to translate rotation of the input rotational member to the output rotational member;
- and
- an idler positioning facility configured to create frictional contact between the idler wheels and the input and output rotational members and translate the idler shaft and first and second idler wheels across the input and output rotational members along the shared tangential, wherein the idler shaft is rotatably connected to the idler positioning facility, wherein the idler positioning facility further comprises:
- a spring loaded positioning mechanism configured to maintain contact between the idler wheels and the input and output rotational members.
An idler system for a cone-and-idler continuously variable transmission, the system comprising:
- an idler shaft having a first end and a second end;
- a first idler wheel on the first end of the idler shaft;
- a second idler wheel on the second end of the idler shaft;
- and
- an idler positioning facility configured to maintain frictional contact between the first and second idler wheels and a driving rotational member having a first circular input end and a first circular output end and a driven rotational member having a second circular input end and a second circular output end, wherein the driving rotational member is connected to an engine output and the driven rotational member is attached to a drive shaft and the first circular input end, second circular input end, first circular output end and second circular output end share a tangential plane.
