Patent
CA 2195721
A snowmobile having a lightweight fabricated frame assembly. The frame assembly includes a number of reinforcing elements, some of which comprise heat exchangers for the liquid cooling system of the engine, so as to provide high rigidity and light weight. The engine of the snowmobile is provided with an exhaust system that permits a relatively short effective length, but minimizes pulse-back effects by forming internal expansion chambers around the exhaust branch pipes. The drive for the snowmobile includes a reversing transmission and a brake assembly associated therewith in addition to a main brake assembly for the snowmobile. Furthermore, there is provided a parking brake assembly that is easy to operate and which will provide the operator with a visual and physical warning of its condition so that the operator will not attempt to operate the snowmobile with the parking brake engaged.
