TRACK DRIVE SPROCKETS AND HUB.
Hub transmits torque from final drive output
shafts on each side of vehicle hull to sprockets bolted to hub.
Sprockets mesh with end
connectors on inner and outer edges of track to move track forward over track support
rollers and roadwheels.
VOLUTE BUMP SPRINGS. Bump springs mounted at roadwheels 1 thru 6 on both sides of
hull cushion roadwheel arms into bump stops welded to hull when arm displaced to full
upward travel.
SHOCK ABSORBERS. Shock absorbers, connected to roadwheel arms 1, 2, and 6, dampen
bounce and return cycles of roadwheel arms when driving over uneven surfaces. ‘
