US Patent 11181177 Torque vectoring device

A downsized torque vectoring device that is easily to be mounted on an automobile. The torque vectoring device comprises: a differential mechanism that allows a first driveshaft and second driveshaft to rotate at different speeds; an actuator that applies a control torque to the differential mechanism to rotate the first driveshaft and the second driveshaft at different speeds; and a reversing mechanism that allows the first driveshaft and the second driveshaft to rotate in opposite directions. A gear ratio of a first gear train and a gear ratio of the second gear train are different from each other.
