AUTOMATIC INFINTELY VARIABLE MEACHANICVAL TRANSMISSION Russian patent published in 2001 - IPC

FIELD: mechanical engineering; transport engineering; machine tool man7ufacture. SUBSTANCE: proposed transmission includes input shaft 1 and output shaft 2, hollow drive shaft 9 mounted coaxially relative to input shaft and connected with input shaft by means of drive wheels 10, 11 and 12; wheel 12 is intermediate; it is mounted on bearing axle 13 located in housing 14 of transmission. Hollow intermediate shaft 4 is mounted relative to input shaft; main carrier 3 with radial axles 5 is secured on one end of shaft 4; bevel main satellites 6 and additional satellite 15 are fitted on axles 5 for independent rotation. Main satellites are thrown into engagement with immovable bearing wheel 7 secured in housing; additional satellites are thrown into engagement with movable bearing wheel 5 secured on drive shaft 9. Mounted on other end of intermediate shaft is first central wheel 8 of differential gear. Secured on end of input shaft is second central wheel 17 of differential gear; first central wheel and second central wheel are thrown into engagement with satellites 18 of differential gear mounted on carrier 19 which is secured on output shaft. Main and additional satellites are combined with inertial weights made in form of flywheels. Transmission ensures conversion of torque being transmitted due to change of magnitude and directions of vectors of moment of momentum of main and additional satellites at their simultaneous rotation around radial axes 0₁-0₁ of main carrier and axis 0-0 of transmission which is equivalent to their rotation about central point 0¹of intersection of these axes. Transmission of torque is ensured at any relationships of rotation of input and output shafts. EFFECT: enhanced efficiency and reliability. 9 cl, 2 dwg
