An all-terrain vehicle including centrally pivoted bogies on opposite sides of the vehicle body, a primary yoke mounted on the vehicle body and extending crosswise to the vehicle body for coupling the bogies to each other, a secondary yoke mounted on the vehicle body and connected to the vehicle body by hydraulic cylinders at opposite ends thereof, and a selectively actuatable clutch for coupling the secondary yoke to the primary yoke so as to cause the hydraulic cylinders to drive both yokes a desired amount to positively move the bogies to a desired position, and hydraulic circuitry coupled to the hydraulic cylinders for applying a pulsating action to the bogies which is transmitted to the vehicle wheels mounted on opposite ends of the bogies for increasing traction of the wheels on surfaces such as snow, ice, mud and sand. The pulsating action can be applied either when the bogies have been moved to and maintained in a predetermined position or when the bogies are freely pivoting as the vehicle is passing over terrain. A conventional vehicle which includes structure for vertically pulsating individual wheels and changing their elevation relative to the vehicle body.
A vehicle comprising a body, bogies each having a first central portion and first outer end portions with said first central portions of said bogies pivotally mounted on opposite sides of said body for free pivotal movement, wheels mounted on said first outer end portions of said bogies, said free pivotal movement of said bogies occurring as said wheels mounted thereon follow the terrain, a standard on said body, a yoke having a second central portion and second outer end portions with said second central portion pivotally mounted on said standard and said yoke extending crosswise of said body, elongated links having first and second ends, first connecting means movably connecting said second outer end portions of said yoke to said first ends of said elongated links, second connecting means movably connecting said first outer ends of said bogies to said second ends of said elongated links, and selectively actuatable motor means for positively pivoting said yoke to thereby positively pivot said bogies coupled to said yoke to thereby move all of said wheels simultaneously.
A vehicle comprising a body, bogies each having a first central portion and first outer end portions with said first central portions of said bogies pivotally mounted on opposite sides of said body for free pivotal movement, wheels mounted on said first outer end portions of said bogies, said free pivotal movement of said bogies occurring as said wheels mounted thereon follow the terrain, a standard on said body, a yoke having a second central portion and second outer end portions with said second central portion pivotally mounted on said standard and said yoke extending crosswise of said body, elongated links having first and second ends, laterally extending arms having first and second ends, first connecting means movably connecting said second outer end portions of said yoke to said first ends of said elongated links, said first outer ends of said bogies being connected to said first ends of said laterally extending arms, said second ends of said elongated links being connected to said second ends of said laterally extending arms, and said second ends of said laterally extending arms being located substantially over certain of said wheels.
A vehicle comprising a body, bogies each having a first central portion and first outer end portions with said first central portions of said bogies pivotally mounted on opposite sides of said body for free pivotal movement, wheels mounted on said first outer end portions of said bogies, said free pivotal movement of said bogies occurring as said wheels mounted thereon follow the terrain, a standard on said body, a yoke having a second central portion and second outer end portions with said second central portion pivotally mounted on said standard and said yoke extending crosswise of said body, elongated links having first and second ends, first connecting means movably connecting said second outer end portions of said yoke to said first ends of said elongated links, second connecting means movably connecting said first outer ends of said bogies to said second ends of said elongated links, and wherein said vehicle includes first and second ends, and wherein said standard is mounted proximate said first end of said body, and wherein said bogies are connected to said first elongated links proximate said first end of said body, a second standard mounted proximate said second end of said body, a second yoke pivotally mounted on said second standard and extending crosswise of said body, outer end portions on said second yoke, second elongated links having first and second ends, third connecting means movably connecting said outer end portions of said second yoke to said first ends of said second elongated links, and fourth connecting means movably connecting said bogies to said second ends of said second elongated links proximate said second end of said body.
