TREAD BELT AND ASSEMBLY

摘要

An endless tread belt adapted to pass about two or more surface locomotion wheels is formed of an elastomeric material and has a plurality of spaced cleat portions extending generally transversely of the tread belt body; a generally medially situated constraining belt is contained generally within the belt body and positioned so as to have the medial portion thereof coextensive with the pitch diameter of the belt body, the constraining belt or strap is effective for assuring tracking means formed on the tread belt to be closely received within cooperating guide means formed in the surface locomotion wheels; the sides of the tread belt are provided with integrally formed passage-type locking means for receiving therein fingerlike locking members of side closure walls connectable to the tread belt at opposite sides thereof in order to form an enclosed chamber containing the locomotion wheels.
