go kart transmission

Post by Speed Infinite on Thu Mar 26, 2009 9:08 am

Karts do not have a differential.[7][9] The lack of a differential means that one rear tire must slide while cornering; this is achieved by designing the chassis so that the inside rear tire lifts up slightly when the kart turns the corner. This allows the tire to lose some of its grip and slide or lift off the ground completely.

Power is transmitted from the engine to the rear axle by way of a chain. Both engine and axle sprockets are removable; their ratio has to be adapted according to track configuration in order to get the most of the engine.

In the early days, karts were direct drive only, but the inconvenience of that setup soon led to the centrifugal clutch for the club level classes. Dry centrifugal clutches are now used in many categories (Rotax Max is one example) and have become the norm as the top international classes have switched to 125 cc clutched engines as of January 2007.
