Abstract: A suspension system for the front running skis of a snowmobile. Each ski is yieldingly mounted by leaf springs to a steering rod on a snowmobile, and is capable of guiding the vehicle as well as compensating for terrain irregularities. A piston-cylinder shock absorber is pivotally connected at its lower end to the ski, and the upper end is connected to the snowmobile body by means of a ball and socket coupling to dampen oscillatory movement of the ski.

Abstract: The disclosure is directed to an improved centrifugal clutch the structure of which permits its use with engines having different performance characteristics, and enables simple modification resulting in a desired performance relationship with the selected engine. One feature centers on a plurality of flyweights, each having an engageable cam surface that relates engine revolutionsper-minute to the input/output revolution ratio to effect a simulated gear shifting transmission characteristic. Other features are directed to laminated flyweights made of different materials to obtain the proper centrifugal action, and the mounting of flyweights having predetermined centers of mass to obtain the greatest mechanical advantage at the optimum time.
