Abstract:
1. A toroidal continuously variable transmission, comprising: input and output disks rotatable about a common rotation axis; power rollers interposed between the input and output disks; trunnions supporting the power rollers to allow the power rollers to rotate about a rotation axis, respectively, the trunnions being displaceable along a longitudinal axis which extends perpendicular to the common rotation axis of the input and output disks and the rotation axis of the power rollers, the trunnions being pivotally moveable about the longitudinal axis together with the power rollers by cooperation with rotation of the input and output disks; a link connecting the trunnions; a link support supporting the link to allow the displacement of the trunnions along the longitudinal axis and the pivotal movement of the trunnions about the longitudinal axis; and a pin extending in a direction parallel to the common rotation axis of the input and output disks, the pin being disposed on one of the link and the link support; the other of the link and the link support being formed with a groove extending in a direction parallel to the longitudinal axis of the trunnions, the groove having an open end open to a surface of the other of the link and the link support, the open end of the groove being open to the surface of the other of the link and the link support in a direction parallel to the longitudinal axis of the trunnions, the pin being permitted to be radially inserted into the groove through the open end of the groove in the direction parallel to the longitudinal axis of the trunnions, the pin and the groove cooperating to hold the link in place in a direction perpendicular to the common rotation axis of the input and output disks and support the link to allow the link to swing about the pin and offset in the direction parallel to the longitudinal axis of the trunnions.
