WEDGE-AND-CHAIN VARIABLE-SPEED DRIVE Russian patent published in 2008 - IPC F16H7/06 F16H9/24 F16G13/02 F16H59/06 B60K17/06 

Abstract RU 2321786 C2

FIELD: mechanical engineering; transport engineering.

SUBSTANCE: invention relates to transmissions with stepless change of gear ratio. Proposed variable-speed drive contains input shaft, output shaft, two driving pulleys, one of which is fixed and the other is movable, installed for axial displacement of fixed driving pulley, drive chain two driven pulleys, one of which is fixed and the other is movable, installed for axial displacement of fixed driven pulley. Movable and fixed pulley are arranged in crosswise manner. Variable-speed drive is provided with input and output pressure devices consisting of pressure bushing with paths of pressure device with variable angle of pressing, rollers and paths of pressure device with variable angle of pressing made on input and output shafts.

EFFECT: reduced overall dimensions of variable-speed drive, increased load-carrying capacity of drive chain.
