The rear wheels are connected to the chassis by a wheel support assembly configured for allowing movement of each rear wheel relative to the chassis, a hydraulic cylinder connected to the chassis and the rear wheel supports, and a piston connected the rear wheel supports and the chassis. The piston dividing the hydraulic cylinder into fluidly connected first and second chambers such that movement of hydraulic fluid from the first or second chamber of a hydraulic cylinder to the respective first or second chamber of another hydraulic cylinder displaces the pistons of the hydraulic cylinders in opposing directions relative to the respective housings and causes the chassis to articulate with respect to the surface.Type: ApplicationFiled: January 7, 2011Publication date: March 21, 2013Inventor: David Andrew Gale

Publication number: 20130056969Abstract: A front fork assembly for use with a three-wheel agricultural floater has a yoke having a first yoke portion and a second yoke portion extending downwardly from generally opposite ends of an upper yoke portion. A first plurality of wheel mounting points is formed on the first yoke portion and a second plurality of wheel mounting points is formed on the second yoke portion. The front fork assembly further includes a first wheel mounting arrangement formed from selected mounting points of the first plurality and the second plurality of mounting points. A second wheel mounting arrangement, different from the first wheel mounting arrangement, is formed from selected mounting points of the first plurality and the second plurality of mounting points. In this regard, the front fork assembly provides more than one mounting position for a front floatation tire.Type: ApplicationFiled: September 7, 2011Publication date: March 7, 2013Inventors: Rex L. Ruppert, Greg Fischer

Patent number: 8376372Abstract: A multiple wheel vehicle according to the present invention enables to incline freely the two wheels together with the vehicle body while keeping the ground contacting pressures of the two wheels equal. The multiple wheel vehicle comprises a pair of swinging arms 4 each comprising one-side end portion supported pivotably with right and left support shaft portions 3A and an interlocking device 6 for interlocking them alternately up-and-down. The interlocking device 6 comprises a pair of tilted members 17, a divertible member 19, and a cord-like body 20 connecting them. Each of the tilted members 17 comprises a first circular surface part 21 that has a center of a circular arc as a shaft center 3i of the support shaft portion 3A, and tiltably supported integrally with the swinging arm 4.Type: GrantFiled: January 12, 2010Date of Patent: February 19, 2013Inventor: Kinya Kanou

Patent number: 8317207Abstract: A leaning vehicle has a frame pivotally connected to the lower end of a shock tower, the pivotal connection defining a frame leaning axis wherein the frame is adapted to lean to a right side and to a left side relative to the shock tower about the frame leaning axis. An actuated lock locks the frame to the shock tower and prevents relative movement between the frame and the shock tower about the frame leaning axis.Type: GrantFiled: January 26, 2012Date of Patent: November 27, 2012Assignee: Bombardier Recreational Products Inc.Inventor: Daniel Mercier

Patent number: 8262114Abstract: A tool-less coupling of a child vehicle having a front frame and a rear frame includes a post coupled to one of the front or rear frames; a locking insert having at least one flexible table coupled to the post, and a head tube coupled to the other of the front or rear frame, wherein an opening in a first end of the head tube is sized to cause inward flexing of the flexible tab as the post is inserted through the head tube, and the flexible tab flexes back outwardly after passing through the opening in the head tube so that a portion of the flexible tab is adjacent an end surface of the head tube such that the flexible tab cannot move back through the opening. Accordingly, the removal of the post from the head tube is prohibited and the front and rear frames are coupled together. A method for a tool-less assembly of a child vehicle is also disclosed.Type: GrantFiled: February 16, 2010Date of Patent: September 11, 2012Assignee: Huffy CorporationInventor: Donald K. Jessie, Jr.

Patent number: RE44854Abstract: A three wheeled vehicle that has an improved dual front wheel integrated steering and suspension system that allows the vehicle to be maneuvered by a combination of arm and leg steering movements coupled with front end leaning that shifts the center of mass of the vehicle down and toward the inside wheel. This transfer of mass counteracts a conventional cornering vehicle's tendency to fling its mass to the outside wheel and lift the inner wheel off the ground as well as changing the angle of the line of force exerted through the tires, and enhancing the vehicles's grip on the ground. The vehicle has a reduced amount of sliding and potential of flipping when turning sharply. The steering system is compatible with traditional ACKERMAN steering geometry wherein the inner wheel turns in a smaller diameter circle than the outer wheel.Type: GrantFiled: June 26, 2012Date of Patent: April 22, 2014Inventor: Laddie Gene Henderson
