  • Speed change transmission arrangement including a continuously variable toroidal transmission
    Patent number: 6726590
    Abstract: In a variable-speed transmission arrangement, a continuously variable toroidal transmission and a planetary aggregating transmission are arranged in the power path between an input shaft and a coaxial output shaft. A central intermediate shaft is mounted to the input shaft for rotation therewith and to an input disc of the toroidal transmission. A planet carrier is connected firmly to the central intermediate shaft which passes through a concentric intermediate shaft, to which an output disc of the toroidal transmission and a second transmission member of the output transmission are connected. A third transmission member of the aggregating transmission is connectable to the output shaft, by means of a first clutch in a low mode, and a fourth transmission member of the aggregating transmission is connectable to the output shaft by means of a second clutch in an upper driving mode.

  • Infinitely variable speed transmission having two V-belt pulleys
    Patent number: 6050911
    Abstract: An infinitely variable speed transmission in which the transmission ratio results from the equilibrium of the total contact pressure force on the one V-belt pulley and the contact pressure force on the other V-belt pulley determined by a V-belt. The total contact pressure force having a torque-dependent proportion and a proportion which is a function of at least one outside operating parameter.
