Abstract
Disclosed herein is a vehicle steering device, comprising, a pancake harmonic drive with an external wave generator surrounding a flex spline that is in mesh with both a tooth matched spline and a dynamic spline, a rotatable input shaft in operable communication with the harmonic drive, a rotatable output shaft in operable communication with the harmonic drive, and a motor in operable communication with the wave generator, and the gear ratio of the input shaft to the output shaft is altered by rotation of the motor.
