Question 1

There are four primary types of electric power assist steering systems, including all of the following EXCEPT:

Accepted Answer

Hydraulic-assist type is not an electric power assist steering system; it uses hydraulic fluid to assist steering, unlike the other options which are electric-based systems.

Question 2

The ______ use(s) principles of gear reduction to give the driver mechanical advantage over the wheels, making it easier to steer them.

Accepted Answer

The steering box uses principles of gear reduction to provide the driver with a mechanical advantage, making it easier to steer the wheels.

Question 3

The _________ connects the center link to the steering arms.

Accepted Answer

The tie-rod connects the center link to the steering arms, allowing for the transfer of motion from the steering gear to the wheels.

Question 4

Reduction ratio is measured in:

Accepted Answer

Reduction ratio is typically measured in degrees, as it refers to the angular displacement or reduction in speed in mechanical systems like gear trains.

Question 5

There are two main types of steering systems used on vehicles today. They include:

Accepted Answer

Rack and pinion is a type of steering system that uses a gear rack and a pinion gear to convert the rotational motion of the steering wheel into the linear motion of the steering linkage. Parallelogram is a type of steering system that uses a parallelogram linkage to convert the rotational motion of the steering wheel into the linear motion of the steering linkage.

Question 6

The ________ is a rotating gear that meshes with the rack.

Accepted Answer

The pinion gear is the rotating gear that meshes with the rack in a rack and pinion mechanism, commonly used in steering systems and other applications requiring linear motion.

Question 7

Technician A says that the worm gear transmits more road shock. Technician B says that the rack-and-pinion gives greater road feel. Who is correct?

Accepted Answer

Technician B is correct because rack-and-pinion steering systems are known for providing better road feel compared to worm gear systems, which tend to isolate the driver more from road feedback.

Question 8

Choose the correct statement:

Accepted Answer

The answer of Choose the correct statement:
...

Question 9

Which type of gear box uses a recalculating ball steering box in it?

Accepted Answer

The worm-and-nut type of gearbox uses a recirculating ball mechanism, which reduces friction and wear by using ball bearings to transfer motion.

Question 10

Which of the following electric power assist steering systems has the power assist unit, controller, and torque sensor connected to the steering column?

Accepted Answer

The column-assist type electric power steering system has the power assist unit, controller, and torque sensor all integrated into the steering column, providing assistance directly at the column.

Question 11

Tech A says that the device that tells the power steering controller how fast the steering wheel is turning and how much assist to provide is called the torque sensor. Tech B says that the steering sensor converts the motion of the steering wheel into a voltage signal for the controller. Who is right?

Accepted Answer

Both Tech A and Tech B are correct. The torque sensor measures the force applied to the steering wheel and helps determine the amount of assist needed. The steering sensor converts the motion of the steering wheel into a voltage signal for the controller.

Question 12

In modern computer-controlled four-wheel steering, an actuator similar to a front rack-and-pinion assembly attaches to the rear steering knuckles with:

Accepted Answer

In modern four-wheel steering systems, the actuator connects to the rear steering knuckles using tie rod ends, similar to the front steering mechanism.

Question 13

The steering box converts the rotary motion of the steering wheel into:

Accepted Answer

The answer of The steering box converts the rotary motion...

Question 14

The _________ converts the rotary motion of the steering wheel into the linear motion needed to pivot the wheels.

Accepted Answer

The steering gear is responsible for converting the rotary motion of the steering wheel into the linear motion required to pivot the wheels.

Question 15

Tech A says that worn rack-and-pinion mount bushings can cause excessive play in the steering system. Tech B says that a worn idler arm can cause excessive play in the steering system. Who is correct?

Accepted Answer

Both Tech A and Tech B are correct. Worn rack-and-pinion mount bushings can lead to excessive play in the steering system, as they are responsible for securing the rack-and-pinion assembly. Similarly, a worn idler arm can also cause excessive play, as it is a critical component in maintaining the alignment and stability of the steering linkage.

Question 16

Tech A says that rack-and-pinion steering systems generally do not use power steering due to their lighter duty construction. Tech B says that rack-and-pinion steering systems use a worm gear arrangement to move the rack. Who is correct?

Accepted Answer

Rack-and-pinion steering systems often do use power steering, and they do not use a worm gear arrangement; instead, they use a pinion gear to move the rack.

Question 17

Tech A says that when the vehicle is being driven straight ahead, a belt-driven power steering pump will pump fluid continuously, placing a minimal load on the engine. Tech B says that a belt-driven power steering pump is activated by an electromagnetic clutch, so it only pumps fluid when the wheels are being steered. Who is correct?

Accepted Answer

Tech A is correct because a belt-driven power steering pump continuously pumps fluid, even when driving straight, placing a minimal load on the engine. Tech B is incorrect as belt-driven pumps do not use an electromagnetic clutch.

Question 18

Technician A says that power steering fluid is universal and can be used in virtually any vehicle's power steering system. Technician B says that in a power steering system, the force needed to turn the wheels is created by the hydraulic pump or electric motor. Who is correct?

Accepted Answer

Technician B is correct because the force needed to turn the wheels in a power steering system is indeed created by the hydraulic pump or electric motor. Technician A is incorrect as power steering fluid is not universal; different vehicles may require specific types of fluid.

Question 19

Technician A says that using the wrong power steering fluid can cause damage to the power steering system. Technician B says that using the incorrect fluid can result in the creation of excessive pressure that can cause leaks, loss of assist, or even a fire hazard. Who is correct?

Accepted Answer

Using the wrong power steering fluid can indeed cause damage to the system, as Technician A states, and it can also lead to excessive pressure, leaks, loss of assist, or even a fire hazard, as Technician B mentions. Both technicians are correct.

Question 20

Technician A says that the steering torque sensor and the steering angle sensor are compared to determine the amount of electrical assist that is needed. Technician B says that a steering angle sensor may need to be calibrated after performing certain repairs. Who is correct?

Accepted Answer

Technician A is correct because the steering torque sensor and steering angle sensor are used to determine the necessary electrical assist in power steering systems. Technician B is also correct because the steering angle sensor often requires calibration after certain repairs to ensure proper functionality.
