Abstract
A continuously variable transmission including a drive element rotatable about a drive axis, an output element rotatable about an output axis parallel to the drive axis, and an adjusting mechanism with which the drive axis and the output axis can be laterally offset from each other. Coupling elements operate between the drive element and the output element and are spaced from each other in the peripheral direction of the drive element and output element for transmitting torque between the elements. The coupling elements change the movement of a peripheral region of the drive element faster than that of the output element so that forces acting on the coupling elements from the drive element and the output element lie substantially in a common plane that extends perpendicularly to the axes of rotation. The continuously variable transmission can be incorporated into a transfer case for an all-wheel drive system.
