AG TRACK DEFINITIONS
Alignment: Referring to relative parallelism of drive wheels, idlers, and bogies.
Bogie: Free rolling wheels with purpose of of distributing machine load over the track footprint. Also called mid-roller or roller wheel.
Drive Lug: Rubber lugs located on underside of track, with purpose of not only driving the track via drive wheel, but also guiding track within set limits.
Drive Wheel: Direct driving component of rubber track system- either friction or positive drive.
Elongation: After rubber track is strained, deformation causing an increase in length, in many caused by load under normal service.
Guide Lug: Rubber lugs located on underside of track, with purpose of guiding track to prevent de-tracking.
Idlers: Free rolling wheels defining the shape of the track system comprising combination of bends.
Mid-Roller: Free rolling wheels with purpose of of distributing machine load over the track footprint. Also called bogie or roller wheels.
Misalignment: Drive wheels, idlers, and bogies are not running in parallel, resulting in poor track performance and possible failure.
Misengagement: Direct drive track condition in which drive lugs do not engage properly with drive wheel.
Outside Guide Lugs: Guide lugs on edges of track designed to keep drive and idler wheels from de-tracking.
Roller: Synonymous with bogie wheel or mid-roller, designed to distribute load to track in free rolling position.
Ridging: Ground pushed up into berms created by sideward movement of the track.
Skid Steer: No articulation steering methodology, whereby tracks are rotated at different speed to achieve desired steer effect.
Spreading Force: Force applied to track from tensioning system of undercarriage, typically front and rear idler wheels spread apart.
Track Tension: Total tensile load supported by a given span of track ?
Tracking: Refers to tracks propensity to run as designed, not moving laterally or scrubbing guide lugs.
Tractive Effort: Tractor maximum drawbar pull vs total weight.
Tread Lug: Rubber lug located on the ground engaging surface of the track providing traction.
Undercarriage: Components supporting track structure including drive wheels, idlers, mid-rollers, and frame.
Wheelbase: Distance from center of front wheel to center of rear wheel in track system.
