摘要

Rocker arms are more important than today's high performance valvetrains. The rocker arms play a more important role than ever these days in high performance valvetrains. The rockers are the teeter-totters that translate the upward motion of the lifters and pushrods to the downward motion that opens the valves. It seems like a relatively simple task, but it demands the utmost from the design of the rockers and the materials from which they are made. Aluminum roller rockers with roller needle bearing fulcrums and roller tips have been around for decades. The main advantage with the roller rockers is that they reduce friction compared to a standard stamped steel or cast iron rocker arm. The basic technology has not changed that much over the years. What has changed are the lift ratios that some of today's rockers are capable of delivering, the high valve spring loads rocker arms in some high revving engines have to handle, and the strength and durability requirements that end users have come to expect from a set of high end performance rocker arms.
