SYSTEM OF TRANSMISSION WITH CONSTANTLY CHANGING GEAR RATIO Russian patent published in 2007 - IPC F16H37/08 

FIELD: mechanical engineering.

SUBSTANCE: proposed system of transmission with constantly changing gear ratio has input and output shafts, 16 and 24, respectively, transfer unit V with constantly changing gear ratio connected to input shaft 16, mixed epicyclical transfer mechanism E1 and second epicyclical transfer mechanism E2. Mechanism E1 has input sun gear S1 connected to output shaft of variable speed drive 18, carrier C1 connected to input shaft 16 and planetary gear P1 installed on carrier C1. Planetary gear P1 drives first intermediate output shaft 32 selectively connected to output shaft 24 of system through first clutch H at high speed of system. Planetary gear P1 provides also input power for second epicyclical transfer mechanism E2. Mechanism E2 has output C2 which is selectively connected to output shaft 24 of system through brake member L at low speeds of system.

EFFECT: minimization of engagement of gears, thus minimizing transmission losses, no backlash in mechanism E1, increased range of selection of sizes of gears, thus reducing speed of gears.
