SYSTEMS OPERATION - Continued
(E) 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.
(F) VOLUTE BUMP SPRINGS AND SHOCK ABSORBERS. Bump springs mounted at roadwheels
1 and 6 on both sides of hull cushion roadwheel arms into bump stops welded to hull when
arm displaced to full upward travel.
Shock absorbers, connected to roadwheel arms 1, 2,
and 6, dampen bounce and return cycles of roadwheel arms when driving over uneven
surfaces.
