FRICTION DYNAMIC VARIATOR Russian patent published in 2015 - IPC F16H15/42 F16H9/00 

FIELD: machine building.

SUBSTANCE: variator comprises a guide link in the form of a friction wheel (1) with internal engagement, an inertial element in the form of an endless chain (2), an endless flat spring (3), driven link (4) with a supporting wheel (5), a reaction wheel (8). The endless chain (2) is set inside the friction wheel (1) and interacts with it along the inner side of its circumference. The supporting wheel (5) is installed on the movable lever (6) and can shift in radial direction. At the guide link rotation the chain is involved in the rotation and is pressed to the inner surface of the friction wheel due to the centrifugal force. The support wheel (5) shifting in radial direction can be ensure smooth engagement of the guide and driven links of the variator, and stepless change of torque on the output shaft.

EFFECT: improved operability of the dynamic variator.
