Patent number: 11679840Abstract: A snow vehicle is disclosed comprising a vehicle frame, a propulsion unit coupled to the frame, and at least one front ski steered by a steering mechanism. The front of the vehicle includes a first front suspension and a second front suspension coupled to the ski. The rear suspension includes a bumper assembly preventing bottoming out of the rear suspension. The rear suspension is coupled to the vehicle frame such that the longitudinal spacing between the vehicle frame and rear suspension is adjustably controllable.Type: GrantFiled: September 11, 2020Date of Patent: June 20, 2023Assignee: Polaris Industries Inc.Inventors: Allen M. Mangum, Justin R. York

Patent number: 10960914Abstract: A front fork assembly of a snow bike is disclosed having left and right legs, each having an upper leg portion and a lower leg portion. The left leg upper and lower leg portions are linearly movable relative to each other. A right leg has an upper leg portion and a lower leg portion, the right leg upper and lower leg portions are linearly movable relative to each other. A ski mount has a lower end for coupling to a ski and an upper end for coupling to the left and right leg. A linear force element is coupled to the left and right legs with a first end adjacent the first ends of the forks and seconds ends coupled to the ski, the linear force element has a different linear force characteristic than the left and right legs.Type: GrantFiled: January 3, 2020Date of Patent: March 30, 2021Assignee: Polaris Industries Inc.Inventors: Allen M.
