HIGH-TORQUE VARIATOR OF NONRYCING TYPE Russian patent published in 2017 - IPC F16H29/02 

FIELD: machine engineering.

SUBSTANCE: variator contains a housing (1) installed in the input (2) and output (3) shafts, a gear change mechanism with a control handle (17), mounted on the input shaft with the possibility of joint rotation, a spatial cam (4), a three-shaft gear differential, the drive shaft of which is the output shaft. The shafts of the differential wheels (24a, 24b) are equipped with two drive mechanisms. Each of the mechanisms includes a pair of shafts mounted on the bearings in the housing parallel to the input shaft and a pair of overrunning couplings, with the drive wheels of the differential kinematically connected to the shaft by driven coupling halves. Each leading half-coupling is kinematically connected with the oscillating shaft. On the oscillating shafts, the levers (6) that are in contact with the spatial cam are installed carousel in one plane, with the possibility of changing the handle of the relative position of the spatial cam and the levers. The axes of the oscillating shafts are set at the same distance from the axis of the input shaft. The axes of each pair of oscillation shafts are mounted in a plane passing through the axis of the input shaft. The planes are perpendicular to different pairs of vibrational shafts, and the vibrational shafts in each pair are kinematically connected to the possibility of rotation with a uniformly differently directed angular velocity, for example, a chain transmission (19).

EFFECT: simplification and cheapening of construction.
