<p>The present invention provides a track-type carriage system for heavy vehicles, and, in the preferred embodiment, a track-type carriage system for an articulated steering seismic vibrator vehicle. The carriage system consists of four track modules (30), two fore and two aft, each independently mounted at one end of a heavy axle (48) and bearing a proportionate share of the vehicle weight as applied to the track module (30) via a ground pressure cylinder (76). Each track module (30) includes an S-shaped frame (36) interrelating a large drive wheel (54) mounted to the axle (48), a pair of forwardly mounted idler wheels (56) and a plurality of mid-wheels (70). A stabilizing mechanism (82) manages torsional and lateral forces and also accommodates for fore and aft movement of the track module frame (36).</p> |
