ABSTRACT:
The present invention provides a power transmission belt for transferring power between two power transfer members. The belt includes a resilient binder and a plurality of traction blocks spaced apart from one another and formed integrally with the binder. The traction blocks are formed from a dense, abrasion-resistant material for bitingly and frictionally engaging a wall of the power transfer members. The binder is preferably formed from an elastomeric material. Preferably, the belt has a substantially V-shaped cross section and the traction blocks extend laterally outwardly from at least one of the side walls of the belt.
