A tooth jump protection device is used to control chain slack and delay the torque at which chain jump occurs, thus increasing jump torque performance. The tooth jump protection device is preferably mounted to the transfer case.

Tooth jump protection device

A bicycle chain which includes internal links which are formed to act as both a rotating joint for the pin and a supporting surface for the roller. Two internal links together form an internal link assembly, along with rollers and bushings.

Bicycle chain with bushing link

A pattern for application to the face of the tensioner arm, guide or snubber in contact with a chain to intentionally break up the chain contact force between the back of the chain links and the tensioner arm, guide or snubber face. This is done to prevent alignment with the chain related orders which are causing NVH within the chain system or to increase overall NVH to obscure chain related orders.

Face of tensioner guide or arm with pattern to influence chain system NVH performance

A chain tensioning device which combats natural build-up of chain slack. In controlling the chain slack, the torque at which a chain jumps occurs is delayed resulting in a higher jump torque performance.
