Abstract
A track tensioning system for a tracked vehicle having both a frame with left and right side members as well as left and right tracks that are both configured to translate along the ground to move the vehicle includes left and right wheel plates located substantially adjacent to a respective side member. Left and right wheels are coupled to the respective left and right wheel plates. The left and right wheels are coupled to the left and right tracks and rotate on a rotational axis so that, as the tracks translate along the ground, both wheels rotate with the tracks. For providing track tensioning to the tracks, each wheel plate pivots against the respective side member of the frame on a pivot axis that is displaced form the rotational axis. The left and right wheel plates may pivot in substantially parallel pivot planes. The substantially parallel pivot planes may be vertical. The left wheel plate may pivot around a left pivot axis and the right pivot plate may pivot around a right pivot axis. The left pivot axis and right pivot axis may be collinear. The left wheel plate and right wheel plate may be coupled together with a bolt extending along the pivot axis. The wheel plates may each be pivotably coupled to the frame with a bushing.
