POWER TRANSMISSION DEVICE (VARIANTS) AND CONTINUOUSLY VARIABLE TRANSMISSION Russian patent published in 2005 - IPC

FIELD: mechanical engineering, particularly continuous transmissions used as wide-range transmission mechanism.

SUBSTANCE: device for power transmission with variable velocity ratio comprises input 21 and output 27 members, leading draft member 7 and disc member 1 rotationally installed in case. Input member 21 transmits rotational moment of at least one leading draft member 7. Disc member 1 is coaxial to rotary shaft 2 brought into drive connection with at least one leading draft member 7 and is formed as driven member. Disc member 1 may be selectively moved in axial direction along rotary shaft 2 to change position of disc member 1 relative at least one leading draft member 7 to selectively change draft velocity ratio between leading draft member 7 and disc member 1. Output member 27 is displaced by rotary shaft 2 and is selectively brought into engagement with it to transmit rotational moment under determined velocity ratio relative input member 21.

EFFECT: extended velocity range.
