Question

The gear in the steering gear box assembly not only steers the front wheels, but at the same time they can act as reduction gears, reducing steering wheel turning efforts by increasing the ............... .

• A. output torque
• B. gear ratio
• C. turning angle
• D. scrub radius

Hint:

Tip: Bigger gear ratio = easier turns but more wheel revolutions!

Answer 1

The Correct Option is B

In a steering gear box, the gears transmit the motion from the steering wheel to the steering linkage.
They also work as reduction gears, which means they reduce the input force required to turn the wheels.
This is done by increasing the gear ratio.
A higher gear ratio means the driver turns the steering wheel more turns, but with less effort, to achieve the same wheel movement.
The gear ratio directly multiplies the driver’s input torque, making steering easier, especially at low speeds.
Output torque is an effect of the gear ratio, not the gear’s design objective itself.
Turning angle and scrub radius are unrelated to the reduction function of the gear box.
Therefore, the correct answer is gear ratio.
