Patent number: 9873316Abstract: An ATV is disclosed having a frame and a plurality of wheels. A power train is defined by an engine, transmission and front and rear final drives. The engine is mounted to the frame skid plate by way of die cast legs. The transmission may include a CVT, which includes a cooling system to cool the interior of the CVT. The cooling system include a fan positioned on the driven clutch causing a reverse suction air flow, back through the drive clutch, with the air exhausting at the front of the engine.Type: GrantFiled: March 13, 2014Date of Patent: January 23, 2018Assignee: Polaris Industries Inc.Inventors: Jeff S.

Patent number: 8950290Abstract: A vehicle is described having a transmission driven through a propulsion unit such as an engine, and through a CVT. The transmission is comprised of an input shaft and an output shaft which are coaxially disposed. An idler shaft is driven by the input shaft, and the idler shaft drives the output shaft, through selected gear sets, to provide different gear ratios or drive directions. The CVT also has a fan on the driven side which feeds air through the CVT for cooling. The CVT comprises a drive side clutch and a driven side clutch with the output shaft of the extending through the CVT driven clutch.Type: GrantFiled: November 1, 2011Date of Patent: February 10, 2015Assignee: Polaris Industries Inc.Inventors: Benjamin J. Dieter, Alan S. Olson, Daniel Scott Weber, William Burt Rodriguez, John D. Schreier, Stephen L. Nelson, Ron R. Danielson, Roy A. Sunsdahl

Patent number: 6270106Abstract: An all terrain vehicle with a foot-shifted manual transmission and a full platform-style footrest. The all terrain vehicle has a chassis carrying a straddle-type seat which is sufficiently narrow to be straddled by a rider. A laterally extending footrest is provided on each side of the chassis. The manual transmission includes a foot-operable shift lever located on one side of the chassis adjacent the footrest for shifting the transmission among a plurality of forward gears. The footrest is generally rectangular, having generally horizontal heel and toe portions, and the shift lever is positioned at approximately the same height as the heel portion. The toe portion is positioned lower than the heel portion, permitting a rider to depress the shift lever to a position lower than the heel portion of the footrest to downshift the transmission, and permitting the rider to insert his toe in between the toe portion of the footrest and the shifting lever to move the lever upwards to upshift the transmission.Type: GrantFiled: August 4, 1998Date of Patent: August 7, 2001Assignee: Polaris Industries, Inc.Inventors: Richard R. Maki, Alan S. Olson, Mihai Rasidescu, Timothy S. Wysocki

Patent number: 5344168Abstract: A snowmobile ski comprising a longitudinally extending runner having a bottom surface, a generally flat elongate bar having a top and bottom surface, and a steering skag extending longitudinally of the runner on the bottom side of the bar. The flat bar is generally contoured to abut the bottom surface of the runner, and furthermore extends forwardly beyond the skag and laterally and longitudinally beyond the skag so that a skag track in the snow encountered by the ski and the skag track left by the skag in the snow will be at least partially filled in by the bar.Type: GrantFiled: November 8, 1991Date of Patent: September 6, 1994Assignee: Polaris Industries, L.P.Inventors: Alan S. Olson, Robert W. Przekwas
