ABSTRACT:
A driving arrangement for driving a snowmobile having an improved power transmission system that is comprised of a split engine having two cylinder blocks each containing at least a pair of cylinders with their output shafts connected to each other. A belt drive shaft is journaled by the engine assembly and is driven off the output shafts at the point where they are joined together. The belt drive shaft drives the drive belt of the snowmobile through a variable pulley transmission. Several embodiments of driving connections between the output shafts and the belt drive shaft that accommodate angular motion while transmitting large driving forces are disclosed. These include both splined connections and/or connections including flexible couplings.
