Patent number: 7311166Abstract: This invention relates to an improved snowmobile ski having a vertical fin on the topside of the ski with a surface area large enough to minimize or prevent sideways slippage of the ski during a turn. The fin, if a single fin is used, is located adjacent the outboard edge of the ski. A snowmobile ski with dual topside fins having outwardly projecting lips along the upper edges of said fins has improved performance in deep snow.Type: GrantFiled: January 30, 2006Date of Patent: December 25, 2007Assignee: Starting Line Products, Inc.Inventors: Allen Roberts, Joseph Brigham Hokanson

Patent number: 7311168Abstract: In a rear wheel support structure for a motorcycle or a three-wheeled vehicle in which a proximal end portion of a swing arm is vertically tiltably supported on a vehicle body frame by way of a tilting support shaft, a rear wheel is rotatably supported on the swing arm by way of a rear axle, and a rear shock absorber is interposed between the swing arm and the vehicle body frame. The comfort of the ride is enhanced by ensuring a sufficiently long effective stroke of the rear shock absorber with respect to a stroke of the rear wheel. A tilting support shaft of a swing arm is arranged behind a rear axle in the longitudinal direction of the vehicle.Type: GrantFiled: September 26, 2005Date of Patent: December 25, 2007Assignee: Honda Motor Co., Ltd.Inventor: Kenji Kofuji

Patent number: 7311170Abstract: An all terrain vehicle is capable of preventing the temperature of air supplied to an engine and the temperature of a battery from being excessively increased and has a large minimum ground clearance. An object-mountable supporting box is bridged between left and right frame members of a body frame. A battery is located above a bottom plate of the supporting box. An air cleaner is located between the left and right frame members and rearward relative to the supporting box. An intake passage is located in an area which is between the left and right frame members, above the bottom plate of the supporting box, and beside the battery. An exhaust passage passes through an area above a bottom of the frame body and below the bottom plate of the supporting box.Type: GrantFiled: June 1, 2005Date of Patent: December 25, 2007Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Takashi Isoda, Masayuki Uchiyama

Patent number: 7311172Abstract: A steering system for a straddle carrier includes two side supports with steerable wheels, braces, a hoisting gear, an an upper frame. An operator's cab having a steering wheel is disposed at the upper frame. A servo motor with an inverter is mounted in operative connection with the steering wheel and that operates in four quadrants. The servo motor steers the wheels of the straddle carrier using a steering computer, hydraulic proportional valves, control cylinders, and potentiometers on the side supports.Type: GrantFiled: February 28, 2005Date of Patent: December 25, 2007Assignee: Noell Mobile Systems & Cranes GmbHInventors: Rolf Kuhn, Reinhard Bauer
