ABS (Antilock Braking
System)
ABS Brakingis a system using Computer processors, sensors and rapid
solenoid valves which monitor wheel speed and modulate braking pressure if wheel
lockup is sensed during braking. This safety feature helps drivers retain
control of their vehicle in the event heavy braking is required on slippery
driving surfaces.
AFV (Alternative Fueled
Vehicle)
AFV Covers many vehicles powered by natural gas, propane, hydrogen and
other new fuel sources beyond deisel and gasoline.
Air brake
A braking system which is operated by
compressed air. The air brake system is controlled by the use of an air
compressor, tanks and valves keeping the braking system dis-engaged until
needed.
Air Ride Suspension
Air ride suspension uses heavy duty air-filled rubber bags instead of steel
springs to support a load with much less shock and vibration transferred to load
or rider. Compressed air is supplied by the air brake compressor and reservoir
tanks on most trucks.
Airspring System
A system where a cylinder and plunger
contain air under pressure When the cylinder and plunger are compressed, air is
compressed further and produces a spring effect.
Air Tank
A reservoir for storing air for use in
the air brake system Without this storage tank there would not be enough
air for braking when needed.
Ammeter
A gauge which registers the output of the alternator or generator.
ATC (Automatic Traction Control)
A feature similar to ABS, preventing the drive wheels from
spinning on slippery surfaces by braking individual wheels and/or reducing
engine speed. | ||
