6B.1.2 STEERING GEARBOX
The steering gearbox is constructed as shown in Figure 6B.2. Rotation of the steering wheel
is transmitted to the sector shaft by way of the ball nut screw. At the lower part of the steering
gearbox unit is located the potentiometer which converts slight up-and-down movement of the
steering shaft into a voltage and sends the voltage to the controller.
