Truck Suspension Issues
Truck suspension systems must be designed and built
with the drivers, passengers and safety of other vehicles and pedestrians
in mind from the start. A well designed and fitted truck suspension system
gives the driver more confidence, satisfaction, a better turning radius,
better ride, and safer steering. This makes everyone literally FEEL better
with a more stable and steady ride and provides better cargo transport.
It has been proven that air ride suspension systems improve performance
and handling, increase the longevity of the axles, and safeguard the brakes
and body of the truck from excessive stress.
Electrical systems, air conditioning, and other sensitive
areas of the chassis and body last longer due to less chassis vibrations
when the truck is running with a great suspension system.
Three major types of suspension found on transit trucks
include: mechanical truck suspension systems that use metal leaf springs
to stabilize handling, air suspension systems which feature air bladders
for a smoother ride, and independent systems which allow each wheel to
react separately and individually to road conditions.
These independent systems are the most complicated, and the most expensive,
but offer the best overall performance according to some experts. Independent
suspensions are found on most new motorcoaches and seated tour trucks.
With these sophisticated systems each independent suspension has to be
built to match the individual chassis and body of each make and model
truck to ensure maximum handling, turning and comfort standards.
Mechanical and air-assisted systems are found on the majority of trucks
because they are less costly and easier to repair. Many believe that these
simpler systems are all that is needed for a hauling big truck and think
independent systems are overkill.
All suspension systems are engineered uniquely for every chassis. Engineers
review the axles used when in the initial design phase, they study ride
heights and frame and width variables so each suspension, either mechanical,
air or independent, ends up being a one of a kind custom solution. There
is no way around it.
The fact is, when buying a truck, your suspension system should be inspected
and be in proper working condition, should be built by a quality company,
and you should make sure you can find replacement parts easily - truck
suspension systems can be expensive to repair.
