Abstract:
A cone assembly for a continuous variable transmission, comprising:a) a cone rotatably attached to a shaft along an axis of rotation, b) a torque transmitting member or group of torque transmitting members, which at an axial section of said cone partially wrap around the surface of said cone so as to form a torque transmitting arc, said torque transmitting member(s) are used for torque transmission between one or several means for conveying rotational energy and said cone assembly, said torque transmitting member(s) are rotatably fixed relative to said cone, but are allowed to slide relative to said cone in the axial direction of said cone, sliding of said torque transmitting member(s) in said axial direction changes the pitch diameter of said torque transmitting member(s), which is the diameter of the surface of said cone that coincides with the diameter of said torque transmitting arc at each specific location along the surface of said cone, the arc length of said torque transmitting arc, formed by said torque transmitting member(s), remains constant as said pitch diameter changes.
