The CSC DirectDrive was formed to solve the problem of an inefficient and heavy drive system found on a stock Polaris snowmobile. The silver chain drive system (as seen in Fig. 1) is located in the chassis opposite the engine output shaft. This requires the use of a jackshaft (seen in figure 2) to transfer the power to the chain drive, then transfer the power to the track.
The issue involved with this system are as follows:
The chain drive mechanism has been the industry standard for almost 40 years and due to advancements in gear technology and availability, they present an opportunity for a more efficient and cost effective powertrain system.
