Total questions: 28
Worksheet time: 14mins
The main job of suspension is to maximise:
Engine power
Brake force
Tyre grip and handling stability
Fuel economy
MacPherson strut suspensions use:
Upper and lower arms
A single lower arm and a strut
Leaf springs
Torsion bars only
A double-wishbone system uses:
One arm
Upper and lower “A” arms
No arms
Control blades
In double-wishbone, the lower arm:
Is decorative
Carries most load
Controls engine torque
Performs no function
Trailing arm suspension allows the arm to:
Move sideways
Swing up and down
Rotate fully
Remain fixed
A drawback of trailing arm systems is:
Too expensive
Poor lateral axle location
Too stiff
No shock absorbers
A dead-beam axle is used mostly on:
Rear-wheel-drive
Front-wheel-drive cars (rear axle)
Sports cars only
Trucks only
Control blade suspension improves which of the following?
Brake cooling
Engine power
Interior space
Steering ratio
What does hydropneumatic suspension use?
Air only
Electric motors
Fluid and pressurised gas
Leaf springs
The hydraulic pump in hydropneumatic systems is:
Battery powered
Belt-driven from the engine
Solar powered
Electric only
How do coil springs store energy?
Rotating
Compressing and expanding
Cooling
Collecting fluid
What material is a leaf spring made from?
Rubber
Stacked metal strips
Plastic
Aluminium foil
How do torsion bar springs operate?
Compressing gas
Using hydraulic pressure
Twisting along their axis
Bending sideways
Rubber springs are mainly used for:
Heavy trucks
Vibration isolation
High-speed racing
Engine mounting only
Race suspension focuses on:
Comfort
Maximum handling performance
Ride softness
Durability only
The MacPherson strut upper mount typically contains:
A brake pad
A bearing
A worm gear
A torsion bar
A multi-link suspension is an evolution of:
Dead axle
Leaf spring
Double wishbone
Swing axle
Too-soft suspension causes:
Harsh ride
Excessive body roll
No bounce
Wheel lock
Too-stiff suspension causes:
Body roll
Harsh ride and reduced grip on rough roads
Increased comfort
No vibration
Shock absorbers control:
Ride height
Steering angle
Suspension oscillations
Brake pressure
What is a common result of worn shock absorbers in a vehicle?
Low oil pressure
Excessive bouncing
Better grip
Faster braking
Where does a trailing arm typically attach in a suspension system?
Rear only
The front of the arm, pivoting upward/downward
Top mount
Engine mounts
What feature do hydropneumatic systems offer in vehicle suspension?
No adjustments
Automatic ride-height control
Fixed damping
No dampers
A dead-beam axle is also known as which of the following?
Active axle
Torsion beam
Live axle
Swing axle
What do multi-link suspension systems improve in a vehicle?
Simplicity
Ride and handling precision
Noise
Brake fade
What is the main purpose of a suspension spring in a vehicle?
Steer the vehicle
Support vehicle weight
Slow the vehicle
Align tyres
What does a bump stop prevent in a vehicle's suspension system?
Steering lock
Suspension from bottoming out
Brakes from overheating
Tyres from spinning
A hydropneumatic accumulator stores:
Brake fluid
Engine coolant
Pressurised hydraulic fluid
Air only
