DEFINITION

Classification: 305/197

Having nonmetallic part or component (e.g., at area of engagement):

(under subclass 196) Apparatus including an impact pad or block made of rubber or other elastomeric material to reduce noise, vibration, or wear caused by the engagement of the sprocket and the inflexible components.

(1) Note. The resilient impact lug reduces track noise and wear due to metal-to-metal impact of the track against the sprocket wheel. The initial contact is made by the lug so that the impact energy is absorbed prior to engagement of the track bushings.
