Section 03 CHASSIS PREPARATION
1. Sway bar
2. End lever
3. Cornering force
4. Connector linkage
5. Pivot bushings
By having a sway bar in the suspension, softer springs can be used to achieve a good ride because
the bar will help control roll in a corner. The bar has no affect on ride when traveling straight ahead
over bumps that are even from side to side. However, if only one ski encounters a bump, then the
bar will transfer energy between the springs. This leads to another design decision. The diameter
of the sway bar determines how much spring pressure will be "borrowed" from the opposite
spring. A smaller bar will twist more and not transfer as much energy. A larger diameter bar will
transfer more energy which will reduce chassis roll, but will produce a harsher ride on uneven,
bumpy terrain. A smaller diameter bar will give a more compliant ride on the nasty bumps but it
will allow the chassis to roll more in corners. A cross country sled will use small to medium
diameter bars while oval and Iemans racers will use large diameter bars.
