  • Co-axial drive for a toroidal drive type transmission
    Patent number: 5607372
    Abstract: A transmission having a power input and output that run along the same axis without having to use parallel shafting. The transmission is of the type which includes a toroidal drive and a co-axial drive, with the co-axial drive having a rotating planetary carrier that bisects the reaction path between one disk pair of the toroidal drive.

  • Continuously variable transmission with a hydraulic control system
    Patent number: 5540631
    Abstract: A compact structure is provided for a continuously variable transmission, which provides a more direct application of both load and control forces at the pivot trunnion. Load forces are produced from within the pivot trunnion, providing more direct control over load forces and their effect on contact forces between traction rollers and toric discs. Control forces which establish the desired transmission ratio are applied to the pivot trunnion in a manner which substantially eliminates twisting and squirming of the support rollers. High efficiency in operation, and improved assembly is provided with the compact structure disclosed.
