INFINITELY VARIABLE TRANSMISSION DRIVE COUPLING Russian patent published in 2017 - IPC F16H55/56 F16H9/18 F16D43/10 

FIELD: transportation.

SUBSTANCE: infinitely variable transmission drive system, containing the movable and fixed pulleys and the belt between them, the support plate, the inertial element, the first spring and the sleeve-like element. The stationary pulley is attached to the first shaft, made capable to be connected with the engine output. The support plate is fixed to the first shaft, and engages with the movable pulley to rotate in the engagement. The inertial element is made with ability to move radially, at that with ability of temporarily disconnection from the radial surface of the movable pulley and the radially extending surface of the support plate. The first spring counteracts to the axial movement along the movable pulley first shaft to the fixed pulley. The sleeve-type element, disposed between the movable pulley and the fixed pulley, is capable to rotate together with the belt.

EFFECT: speeding increase.
