Benefits of technology

[0007] More specifically, the method of the invention provides for the rapid formation of a rocker arm by making discrete parts such as by stamping and then integrating the parts such as by welding or brazing techniques, as distinguished from casting the unit with its parts as a whole. The method of the invention provides for adapting the rocker arm for use with many different cylinder valve assemblies utilizing the same basic tooling configurations.

Problems solved by technology

This prior art process requires separate tooling to produce each intake and exhaust component and is often time consuming and / or expensive.

Embodiment Construction

[0015] A rocker arm is described herein for use as part of an engine cylinder assembly. The rocker arm is coupled to push rods and valves for opening and closing the intake and exhaust valves of an engine cylinder. The rocker arm includes a push-rod plate and a valve plate each secured to opposite ends of a tubular member. The push rod socket end and the valve pad end are separated by the linear distance of the tubular member. The push-rod plate and valve pad plate may be formed using a rapid formation process, such as stamping. Thereafter, these respective plates are secured to the appropriate end of the tubular member using well known techniques, such as brazing or welding to form an integrated unit. As used herein, the term integrated unit is intended to connote the assembly of the separate or distinct members, i.e., the two end plates to the central member, to form a unitary structure by suitable means such that the assembly is essentially equivalent to a member that is created ...

Abstract

A method of making a rocker arm is provided that includes the integration, into a single piece, of three separate parts namely, a central longitudinal member, a push-rod plate; and a valve end plate in which the push-rod plate and the valve end plate are secured to opposing ends of the central member to create the integrated rocker arm.

Description

TECHNICAL FIELD [0001] This application is a continuation-in-part of application Ser. No. 10 / 953,952, filed Sep. 29, 2004.[0002] The present invention relates to rocker arm assemblies for internal combustion engines and, in particular, to rocker arms constructed by combining three discrete parts to form an integrated rocker arm composite and to the method for making the rocker arm. The rocker arm assemblies of the present invention have efficient unique lubrication systems and also permit both a bearingless and a roller bearing type rocker arm shaft assembly to be interchangeably mounted in a same engine. BACKGROUND OF THE INVENTION [0003] Rocker arm assemblies are utilized in internal combustion engines for actuating intake and exhaust valves. As an engine cam shaft rotates, a push rod is selectively actuated by cam lobes located on the cam shaft and the push rod, in turn, directs an upward force on one end of a rocker arm to cause the rocker arm to pivot about a mounting shaft. As...
