Patent ID: 8676440

Claim:
A snowmobile suspension system comprising: a chassis of a snowmobile; a skid frame positioned below said chassis; at least one limiter strap connected between said chassis and said skid frame; at least one coupling arm connected between said chassis and said skid frame; at least one front arm connected between said chassis and said skid frame; at least one rear arm connected between said chassis and said skid frame and a linear force device connected to said at least one rear arm; a limiter strap adjustment mechanism connected between said chassis and said at least one limiter strap, wherein said limiter strap adjustment mechanism selectively adjusts the length of said at least one limiter strap; a coupling arm adjustment mechanism connected between said chassis and said at least one coupling arm, wherein said coupling arm adjustment mechanism selectively adjusts the length of said at least one coupling arm; a linear force device adjustment mechanism connected between said chassis and said linear force device, wherein said linear force device adjustment mechanism selectively adjusts the length and angle of said linear force device relative to said at least one rear arm for controlling force displacement characteristics of said at least one rear arm; an electronic control module connected to said chassis, said electronic control module configured to electronically control said selective adjustment of one or more of said limiter strap adjustment mechanism, said coupling arm adjustment mechanism and said linear force adjustment mechanism; and a display connected to said chassis for displaying information concerning said selective adjustment to a driver of said snowmobile and receiving driver commands concerning driver selections for further adjustment settings.
