Abstract
A variable speed ratio transmission wherein conventional pneumatic tires caused to orbit around an annular track to transmit motive forces from the input mechanism to the output mechanism. The tire planes are adjustable relative to the track plane to provide varying roll-skid engagement relationships, and different speed ratios.
Claims5
A variable speed ratio transmission comprising a rotary input mechanism and a rotary output mechanism coaxially aligned for rotation on a single transmission axis;
- said output mechanism including an endless annular track centered on the transmission axis;
- said input mechanism including a rotary shaft on the transmission axis, a cross head extending transverse to the shaft, and a pneumatic tire rotatably mounted at each end of the cross head for planetary orbiting movement around the track surface;
- the tires and track constituting the drive connected between the input and output mechanisms;
- said input mechanism futher comprising means carried by the input shaft for rotatably adjusting the cross head around its axis, whereby the tire rotational planes are enabled to take varying angles relative to the track plane.
