Abstract
Continuously variable transmissions are provided. Various systems provide for co-rotating power transmission or drive members for conveying angular velocity and torque from an input, such as an engine or motor, to an output, such as a drive shaft. Angular velocity and torque input-output ratios are varied by user manipulation of at least one of the power transmission members and resulting change in orientation of curvilinear power transmission members.
Claims20
A continuously variable transmission mechanism comprising:
- a first rotary power transfer member for receiving an input power from an input, the first power transfer member being rotated about a first axis by the input power;
- a second rotary power transfer member for receiving power from the first rotary power transfer member and transmitting the power to an output;
- the first rotary power transfer member and second rotary power transfer member being in frictional torque-transmitting contact with one another;
- wherein an angular velocity of the output varies from an angular velocity of the input as a function of the orientation of the first power transfer member with respect to the second power transfer member, and wherein the first power transfer member is rotatable about a second axis, the second axis being substantially perpendicular to the first axis.
A continuously variable transmission mechanism comprising:
- a first rotary power transfer member for receiving an input power from an input, the first power transfer member being rotated about a first axis by the input power;
- a second rotary power transfer member for receiving power from the first rotary power transfer member and transmitting the power to an output;
- the first rotary power transfer member and second rotary power transfer member being in torque-transmitting contact with one another;
- wherein an angular velocity of the output varies from an angular velocity of the input as a function of the orientation of the first power transfer member with respect to the second power transfer member, and wherein the first power transfer member is rotatable about a second axis, the second axis being substantially perpendicular to the first axis, the first and second axis comprising a point of intersection located approximately at a geometric center of the first rotary power transfer member.
A continuously variable transmission mechanism comprising:
- a first rotary power transfer member comprising a curvilinear outer surface;
- a second rotary power transfer member comprising a curvilinear outer surface;
- the first rotary power transfer member and second rotary power transfer member being in articulating and force transmitting contact with one another;
- wherein an angular velocity of the second rotary power transfer member varies from an angular velocity of the first rotary power transfer member as a function of the orientation of the first power transfer member;
- and
- wherein the first power transfer member is rotatable about a first axis, the first axis comprising a power transmission axis, and the orientation of the first power transfer member is altered by rotation about a second axis, the second axis being substantially perpendicular to the first axis.
