ABSTRACT:
A suspension device in a crawler vehicle has a vehicle body, a pair of parallel spaced swing beams mounted on a rear portion of the vehicle body by a suspension for angular movement about a first axis located substantially longitudinally centrally thereof, a rear idle wheel rotatably supported on a front portion of each of the swing beams for rotation about a second axis, a rear drive wheel rotatably supported on a rear portion of each of the swing beams for rotation about a third axis, a crawler belt trained around the rear idle wheel and the rear drive wheel, and a front wheel rotatably mounted on a front portion of the vehicle body. The distance from the second axis to the first axis is greater than the distance from the first axis to the third axis. The second axis is positioned on a front end of each of the swing beams, and the third axis is positioned between the first axis and a rear end of each of the swing beams. Preferably, the distance from the second axis to the first axis and the distance from the first axis to the third axis have a ratio of about 2:1.
