#1
What is the purpose of camber in vehicle alignment?
To ensure even tire wear
ExplanationCamber ensures even tire contact with the road surface, preventing uneven wear.
#2
What is the term used to describe the angle between the centerline of the tire and a vertical line when viewed from the front?
Camber
ExplanationCamber refers to the tilt of the tire relative to the vertical axis, influencing handling and tire wear.
#3
What does the term 'bump steer' refer to in vehicle steering?
An undesirable change in toe angle during suspension compression or rebound
ExplanationBump steer results in unintended steering inputs due to suspension movement, affecting stability and control.
#4
What is the term used to describe the angle between the steering axis and vertical when viewed from the side of the vehicle?
Caster
ExplanationCaster angle influences steering stability by determining the vehicle's self-centering tendency.
#5
Which alignment adjustment affects the stability of the vehicle at high speeds?
Caster
ExplanationCaster angle influences high-speed stability by affecting the vehicle's self-aligning behavior.
#6
Which component is responsible for converting steering wheel input into motion?
Steering rack
ExplanationThe steering rack translates the rotational motion of the steering wheel into linear motion to steer the wheels.
#7
What is the purpose of toe-in and toe-out in vehicle alignment?
To prevent tire wear
ExplanationToe-in/toe-out adjustment ensures the wheels are properly aligned, reducing tire scrub and wear.
#8
Which steering system provides variable assistance based on vehicle speed and steering wheel input?
Power steering
ExplanationPower steering adjusts assistance to match driving conditions, reducing effort and improving control.
#9
What is the term for the tendency of a vehicle to steer towards the direction of a wheel that has lost traction?
Pull
ExplanationPull is the phenomenon where a vehicle veers in the direction of a wheel with reduced traction.
#10
Which alignment adjustment affects how parallel the wheels are to each other when viewed from the top?
Toe
ExplanationToe adjustment ensures the wheels are parallel when viewed from above, optimizing handling and tire wear.
#11
What is the purpose of the tie rod ends in the steering system?
To transmit steering motion from the steering rack to the steering knuckles
ExplanationTie rod ends relay motion from the steering rack to the steering knuckles, directing wheel movement.
#12
What effect does positive caster have on steering?
Improves straight-line stability
ExplanationPositive caster enhances stability by returning the wheels to the straight-ahead position.
#13
What is the purpose of the steering stabilizer or dampener?
To reduce vibration in the steering wheel
ExplanationThe steering stabilizer minimizes vibrations and feedback, enhancing steering control and comfort.
#14
Which type of steering system uses a hydraulic cylinder and piston arrangement to multiply steering force?
Power steering
ExplanationPower steering employs hydraulic pressure to assist steering, reducing the effort required.
#15
What effect does excessive positive camber have on tire wear?
Uneven wear on the outer edges
ExplanationExcessive positive camber causes the outer edges of the tire to wear prematurely due to reduced contact area.
#16
What does the term 'steering ratio' refer to in vehicle steering?
The ratio of steering wheel movement to wheel movement
ExplanationSteering ratio indicates how much the steering wheel must turn to achieve a certain degree of wheel movement.
#17
Which type of suspension system provides the best compromise between ride comfort and handling?
Multi-link suspension
ExplanationMulti-link suspension offers a balance of comfort and handling by allowing independent wheel movement.
