AUTOMATIC INFINITELY VARIABLE MECHANICAL TRANSMISSION Russian patent published in 2001 - IPC

FIELD: mechanical engineering; transport engineering; machine tool manufacture. SUBSTANCE: proposed transmission input shaft 1 and output shaft 2, inertial braking unit and differential gear. Inertial braking unit includes central bearing wheel 3 mounted for independent rotation on input shaft, carrier with radial axles 7 on which locked external satellites 4 and internal satellites 5 which flywheels 6 are mounted. External satellite is thrown into engagement with central bearing wheel 3 and internal satellite is thrown into engagement with drive wheel 9 of inertial braking unit which is rigidly linked with first central wheel 14 of differential gear by means shaft 10 of inertial braking unit mounted coaxially relative to input shaft 1; its second central wheel 15 is mounted on input shaft 1 and carrier 13 is secured on output shaft 2. Bearing wheel is mechanically linked with input shaft by means of intermediate shaft 22 mounted coaxially relative to input shaft and two pairs of gear wheels (20, 18 and 19, 21) for constant rotation in one direction at higher frequency as compared with input shaft. Two wheels (18 and 19) are secured of bearing shaft 17 mounted in transmission housing 16 and are used as support for conversion of torque and rotational speed. Axes 0-0 of transmission and axes O₁-O₁ of carrier of inertial braking unit intersect at central point O¹,, thus ensuring rotation of satellites (4,5) and flywheels 6 of inertial braking unit relative to this central point O¹ at positive change of directions of vectors of their moment of momentum. Braking torque arising at this is transmitted from drive wheel of internal braking unit to first central wheel of differential gear. EFFECT: possibility of transmission of torque to output shaft at automatic change of its magnitude at inverse relationship versus rotational speed of output shaft. 7 cl, 1 dwg
