Non-repeating sequence of profiles

摘要

This invention relates to an endless traction band that is used to propel snowmobiles and more particularly, to an improved ground-engaging side of the traction band, which helps reduce the noise and vibration levels during the operation of the snowmobile. The various protruding lug configurations defines a predetermined number of different lug profiles, from which the sequence of profiles on the endless band are generated in such a way so that every sequence of profiles is different from one another.
