Abstract
A snow travel vehicle for movement through deep snow which is characterized by a two-part articulated chassis, independent beam suspension for tracks on opposite sides of each of the chassis parts and a hydraulic drive system for the vehicle. The two parts of the articulated chassis are pivotally connected about a vertical axis for limited relative movement for steering and about a horizontal axis for limited relative movement to accommodate ground irregularities. Each track includes a longitudinal "walking" beam pivotally connected at the end of a transverse crossbeam. A cleated tread is tautly supported by a plurality of in-line wheels, one of those wheels being a drive sprocket supported by the "walking" beam. A direct drive hydraulic motor is connected to the drive sprocket. A hydraulic power system is provided connected to each of the hydraulic motors and an internal combustion power system is provided to energize the hydraulic power system.
