HIGH-TORQUE VARIATOR Russian patent published in 2004 - IPC

FIELD: mechanical engineering.

SUBSTANCE: variator has housing (1), input shaft (2), output shaft (3), mechanism for changing gear ratio provided with a handle, two spatial cams (7₁), (7₂), differential, and driving mechanisms. The spatial cams are mounted on input shaft (2) for permitting axial movement. The mechanism for changing gear ratio provides the movement of the spatial cams along the axis of input shaft (2) in opposite directions. Each driving mechanism includes two overrunning clutches (12₁) and (12₂), oscillating shaft (9) provided with the pair of rockers (10₁) and (10₂) mounted on it oppositely to provided fixed arms. The rockers are coupled with the shafts of the differential through the overrunning clutches. The planes of oscillation of the rockers mounted on different driving mechanisms are perpendicular and pass through the axis of the input shaft.

EFFECT: enhanced serviceability, simplified design, and reduced cost.
