Geared motor

The geared motor unit comprises an aluminium casting secured to the car chassis.
Located at the side of the geared motor casting, the servo motor supplies the interlocking gear with a
torque ratio of 22:1 via a worm screw.
The geared motor gear, coaxial and in one piece with the steering column, is made of steel, whilst the
outer ring gear is made of co-moulded plastic. The worm screw and the gear have been designed so
that the angles ensure the reversibility of the coupling.
The metal part of the gear is fitted on the output shaft, which transmits the total steering forces (in
other words the torques from the servo motor and the driver).
The input and output shafts are connected to one another by a "calibrated torsion bar" which allows an
angular movement of between +8° degrees and -8° (mechanical ends of travel prevent the torsion
from being increased further).
If there is resistance at the wheels, the input shaft twists the torsion bar; therefore the input shaft and
the output shaft are offset by an angle proportional to the torque applied to the steering wheel.
