HIGH STIFFNESS LOW MASS ROCKER ARM |
摘要 |
A cam-follower rocker arm is provided comprising a flat single plate body containing an axle that extends perpendicular from the vertical wall area for making contact with a valve and a second pivot point axle. The pivot point for the cam-follower rocker arm may be located centrally or at the end of the cam-follower rocker arm that is opposite the cam-follower rocker arm valve arm. An external cam-follower bearing is mounted on the axle and extends on each side of the flat plate wall. The cam-follower rocker arm of the invention is characterized by a relatively reduced mass and has a stiffness that exceeds limits achieved by known prior art designs for an overhead cam and cam-follower valve train; the gain in stiffness being attributed to the body's flat plate cross-section relative to conventional prior art cam-follower rocker arms that have a U-shape or a dual wall cross-section.
