Variable ratio transmission system comprises first differential transmitting torque and speed from drive motor through second differential to drive driven shaft

摘要

The variable ratio transmission system is composed of a differential (D1) receiving the torque and speed from a motor shaft (A1) which it transmits to another differential (D2) a gear train in order to drive a driven shaft (A2). Brakes controlled by a regulation system act on the gear train to modulate the torque and speed variation according to necessity.
