L2 Chassis - Suspension Lesson

Multiple Choice

What is the benefit of independent suspension

• Beam axle

• Live axle

• Dead axle

Multiple Choice

What is the advantage of lower un sprung weight?

• enhances ride quality and roadholding

• enhances load carrying capacity

• enhances ride quality

• enhances the fuel consumption of a vehicle

Multiple Choice

Which of the following is not a common suspension spring

• Coil Spring

• Leaf Spring

• Clock Spring

• Air Spring

Multiple Choice

What does the suspension spring not do?

• The suspension spring sets the vehicles ride height

• The suspension spring allows the vehicle to remain level

• The suspension spring supports the weight of a vehicles load

• The suspension spring stops the suspension bouncing on a rough surface

Multiple Choice

Another common name for a damper is:

• Road Spring

• Shock Absorber

• Compliance Bush

• Track Rod

Multiple Choice

What is an advantage of adjustable dampers?

• They can be adjusted to account for wear

• They can be adjusted for different surfaces and uses

• They can be adjusted rather than replaced

• They can be adjusted to save fuel and emissions

Multiple Choice

What does an accumulator do in a hydraulic suspension system?

• An accumulator stores hydraulic fluid to absorb shocks and maintain ride height in a hydraulic suspension system.
• An accumulator filters contaminants from the hydraulic fluid.
• An accumulator increases the pressure in the hydraulic system.
• An accumulator cools the hydraulic fluid to prevent overheating.

Multiple Choice

How does a torsion bar provide suspension movement

• A torsion bar uses hydraulic fluid to provide suspension movement.
• A torsion bar relies on springs to absorb impacts.
• A torsion bar provides suspension movement by twisting to absorb impacts and maintain vehicle stability.
• A torsion bar functions by compressing air to maintain vehicle stability.

Multiple Choice

What are the advantages of torsion bar type suspension

• Torsion bars are strong and robust

• Torsion bars give a comfier ride

• Torsion bars are easier to repair

• Torsion bars take up less room than coil springs

Multiple Choice

What does a drop link do on an anti roll bar system

• A drop link connects the anti-roll bar to the suspension, aiding in body roll reduction.
• A drop link connects the anti-roll bar to the engine.
• A drop link is used to adjust tire pressure.
• A drop link increases body roll during turns.

Multiple Choice

How should you test a rubber suspension bush for excessive play?

• Use a pry bar to apply force and check for movement in the bush.
• Check the bush for visible cracks or wear.
• Measure the bush diameter with a caliper.
• Inspect the bush for color fading or discoloration.

Multiple Choice

What material is most suspension bushes made from?

• Rubber

• Nylon

• Polyurethane

• Polyvinyl

Multiple Choice

Ball joints and king and link pins both allow the suspension to travel up and down, and also rotate?

• True

• False

Multiple Choice

What is the purpose of either a pan-hard rod, or watts linkage?

• Prevent side to side movement of the axle

• Prevent up and down movement of the suspension

• Prevent forward and backward axle movement

• Prevent the vehicle from suffering passive rear steering

Multiple Choice

What should the bounce test prove?

• The dampers are working correctly

• The springs are unbroken

• The suspension bushes haven't dried out

• The wishbones are correctly aligned

Multiple Choice

How oscillations would you expect to see when performing a bounce test on a vehicles suspension?

• three

• Five

• four

• six

Multiple Choice

what is the most common spring type used on the front axle of light vehicles?

• torsion bar springs

• coil springs

• leaf springs

Multiple Choice

In relation to suspension what is meant by the term roll?

• leaning movement of the body when turning

• lifting of the front during acceleration

Multiple Choice

unsprung weight can be reduced by fitting:

• steel road wheels

• alloy road wheels

• larger diameter wheels

Multiple Choice

Which type of suspension does not allow each wheel to move independently from the others?

• non independent rear suspension

• torsion bar suspension

• isolastic suspension

• adaptive suspension

Multiple Choice

What is active suspension?

• hydraulic damping controlled by sensors, actuators and an ecu

• manually adjustable friction dampers

Multiple Choice

a damper works by:

• forcing oil through valves to restrict flow

• forcing air through valves to slow its movement

Multiple Choice

Which of the following faults could be caused by worn shock absorbers?

• Increase in braking distance

• Poor vehicle acceleration

• Reduced road spring oscillation

• Decrease in braking distance

Multiple Choice

In vehicle suspension what does the term ‘dive’ refer to?

• The dipping and rising of the vehicle on uneven road surfaces

• The lifting of the front of the vehicle during acceleration

• The leaning movement of the body when turning

• The dipping of the front of the vehicle during braking

Multiple Choice

What is the difference between rake and trail in vehicle steering systems?

• Rake is the angle of the steering axis, while trail is the distance between the steering axis intersection and tyre contact patch.

• Rake is the distance between the wheels, while trail is the angle of the steering axis.

• Rake is the height of the vehicle, while trail is the width of the vehicle.
