ABSTRACT:
This invention relates to a method for transmitting power to and from wheels via a train of links. The wheels have cam actuated members that effectively control the radial position of individual links as they enter, travel around, and exit the wheels; thus, allowing for high operating speeds. The wheels also have cam manipulated members that transmit power to and from the train of links such that the required engagement and disengagement of the wheel and train of links occurs without relative slip greatly reducing wear and allowing for high operating speeds. An arrangement of links is disclosed that is especially suitable and complimentary to the wheels. Other devices are introduced that aid the wheels and train of links as they work. These devices include: a method for guiding the train of links with respect to the centerline of the wheels, devices to control motions of the train of links, a guidance system to allow the train of links to go out of plane and return without adversely affecting operation, and a wheel arrangement that is very useful for the transfer of power to the train of links.
