Suspension and Steering Linkage Systems Flashcards
On a rear wheel drive vehicle equipped with a solid axle and coil springs, the differential assembly is:
a) spring weight
b) unsprung weight
c) neither a) nor b)
d) both a) and b)
b) unsprung weight
The basic working principle of a hydraulic shock absorber is based on:
a) hydraulic fluid compressed in a cylinder
b) hydraulic fluid forced through an orifice
c) sliding friction on a piston
d) air forced through a piston
b) hydraulic fluid forced through an orifice
Active suspensions make instantaneous adjustments to the suspension in response to changes in:
a) acceleration and deceleration
b) steering inputs
c) body roll and G forges
d) any of the above
d) any of the above
A ball joint that receives the force from the coil spring or torsion bar is called a:
a) follower type
b) self-loading type
c) load carrier type
d) preload type
c) load carrier type
The force or weight required to deflect a spring one inch is called:
a) spring rate
b) spring weight
c) unsprung weight
d) spring rebound
a) spring rate
The MacPherson strut suspension:
a) is an all new design
b) eliminates the use of upper control arms
c) is not repairable
d) is only used on foreign cars
b) eliminates the use of upper control arms
The upper ball joint on a SLA suspension with the spring on the lower control arm is:
a) a guiding ball joint
b) a load carrying ball joint
c) always compression loaded
d) always tension loaded
a) a guiding ball joint
Tie rods are positioned to closely match the travel of the lower control arms to:
a) prevent damage while driving over rocky roads
b) prevent excessive changes in toe during suspension travel
c) allow the vehicle to be driven a short distance, if the tie rod should break
d) prevent binding between the control arms and the tie rods
d) prevent binding between the control arms and the tie rods
A stabilizer (anti-sway) bar is attached to a car to lower control arms in order to:
a) control body roll
b) increase the car load carrying capacity
c) provide a softer ride over uneven road surfaces
d) allow for easier ride height adjustment
a) control body roll
One advantage of an air suspension is that:
a) ride height is controlled automatically
b) it is cheaper to build and maintain
c) tire imbalance ceases to be a problem
d) all of the above
a) ride height is controlled automatically
Two support members of the parallelogram steering linkage are the:
a) idler and pitman arms
b) idler arm and centre link
c) idler arm and steering arms
d) idler arm and spindle
a) idler and pitman arms
The main purpose of the steering linkage is to:
a) accurately relay steering commands
b) support the steering arms
c) restrict the horizontal motion of the control arm
d) guide the vertical motion of the control arm
a) accurately relay steering commands
Automatic ride control systems use computers to:
a) maintain vehicle ride height
b) firm up the springs under certain driving conditions
c) tighten steering feel at high speed
d) adjust shock absorbers to driving conditions
d) adjust shock absorbers to driving conditions
