Tracks Flashcards
Where are track rollers located
At the bottom of the track to support weight
What do track carriers do
Support the weight of the track
What are the two types of track shoes
Standard grouser
Extreme service track shoe
What are standard grousers used on
Standard vehicle tracks
What are extreme service grousers used on
When operating on rocks and coral
Why are track shoes bolted to track
To increase surface area
What are the two main components of a track system
Track assembly
Track frame
What determines the pump reciprocating distance on a hydrostatic drive
swash plate angle
What powers a hydrostatic drive
Axial piston pump
Motor
What displacement type is a axial piston pump in a hydrostatic drive
Variable displacement
What displacement type is the hydrostatic drive motor
Fixed displacement
With a fixed displacement pump and a fixed displacement motor what is the output
Constant HP and constant torque
With a fixed displacement pump and a variable displacement motor what is the output
Constant HP and variable torque
With a variable displacement pump and a variable displacement motor what is the output
Constant HP and constant torque
What type displacement do you get from a moveable swashplate
Variable displacement
What type displacement do you get from a fixed swashplate
Fixed displacement
How is a hydrostatic drive powered
Engine power is used to make pressurized fluid to drive tracks
What does a hydrostatic drive function as
Clutch and transmission
What system uses steering clutches
Clutch brake system
How does a steering clutch system work
A single power source turns both tracks simultaneously, as the clutch is applied the slowed clutch allows the turn
How are steering brakes applied in planetary steering system
By springs
What are the two types of track master links
Master pin
2 piece master link
What is the advantage of a elevated drive sprocket
Removes shock from the final drive
What do track rollers do
Support vehicle weight
