Compliant chain guide with blade spring 

Patent No. 7,063,635

Issued: June 20, 2006

Inventor: Garcia; Mariano (Ithaca, NY)
Assignee: BorgWarner Inc. (Auburn Hills, MI) 

A chain guide has an elastic member and a wear face. The wear face has the elastic member captured therein. The wear face has an inside surface and an outside surface. The first surface is disposed to contact a chain. The other surface is in contact with the elastic member. Through the compliance of the wear face and the elastic member, the chain guide absorbs some degree of impacts and transverse vibrations, both of which can affect chain control, guide wear, and bracket fatigue.
