Two main types of Air Bag
What is rolling lip and convoluted.
On what style of truck is a walking beam suspension used
What is tandem axle
The difference an OTR truck and a heavy duty truck.
What is OTR = industry and payloads, HD is just big truck
Jounce/rebound is
What is the upward motion of the wheel or compression action and the downward motion of the wheel or return action
Principle of operation of dampers
What is dissipating spring energy, slowing spring travel rate, delaying spring action, ect
The spring that has linear rate
What is rolling lip air bag
Heaviest duty walking beam style
What is solid/R/RS
The weight savings and strength of composite leaf springs
What is up to 85% lighter and material tensile of 10x
Spring rate is
What is he amount of force needed to move the spring a certain distance. (Lbs/in or N/mm)
What classifies as a shock absorber
What is a damper, and NOT a spring
The air spring that has variable rate
What is convoluted air bag
Smoothest walking beam style
What is AR2/air bag
The difference between a spring and damper
What is load support / energy storing>releasing vs shock dissipation / responsiveness control.
Component that tandem axle trucks/trailers use to balance bump load between axles.
What is equalizers
Styles of damper
Integral vs external bypass, or pneumatic vs hydraulic.
Operating pressure of air bags
What is 5-100 psi
Main design feature of walking beam
What is travel distance reduction/articulation
Suspension type that offers high articulation
What is walking beam suspension
The reason coil springs are not used on OTR trucks
What is shock dissipation deficiency, load capacity, durability
Suspension systems that have shock absorbers
Trick question, all OTR systems require shock absorbers
Component that controls ride height
What is tractor/trailer leveling valve
How much lighter is Haulmaax design
What is 690lbs
Secondary suspension components
What is Bolster Springs, Shock Absorbers, torsion rods/bars.
The factors that can affect Jounce and Rebound.
What are spring type, spring rate, damping, and axle weight.
Fluids that are used in pneumatic shock absorbers.
What is hydraulic oil and compressed nitrogen
