ABSTRACT:
A fast reaction steering mechanism including a variable ratio gear mechanism connected in series with a speed increasing gear mechanism which is disposed in a steering transmission for transmitting rotation of a steering wheel to a steering gear box, the variable ratio gear mechanism comprising a first gear connected to the steering wheel having an effective radius gradually increasing with an increasing steering angle and a second gear connected to the steering box having an effective radius gradually decreasing with an increasing steering angle, and, with the steering angle at its central position, a smallest-radius portion of the first gear engaging with a largest-radius portion of the second gear, thereby providing a maximum steering angle by a reduced rotation of the steering wheel.
