Webb Wheel Products Inc introduced the newest addition to its wheel end portfolio--a new brake drum optimized for use in trailer applications. The introduction was made at a press conference held in conjunction with Heavy Duty Aftermarket Week (HDAW) at the Mirage in Las Vegas NV.
The new lighter, cooler Webb trailer drum with patented Webb CRT (Cool Running Technology) vents was engineered specifically for 20K trailer axles. Today, many trailers are running with side skirts that improve aerodynamics. However, OTR road data suggests that they can also reduce crosswind and straight line airflow below the trailer. This reduction in air flow results in a 41% increase in brake temperatures, causing reduced braking performance and accelerated brake drum and lining wear.
The Webb 66764F brake drum with patented CRT vents increases air flow for superior heat transfer efficiency and cooler trailer wheel-end operating temperatures, managing heat 10% better than similar weight brake drums.
Johnathon Capps, Webb vice-president of engineering, said: “The push to increase trailer aerodynamics has created opportunities for trailer component suppliers to design products that recognize how these new technologies can change overall trailer functions. Our experience with designing and producing cooler running brake drums directed us to a solution that mitigates the impact of higher brake temperatures caused by the change in air flow.”
The innovative engineering of the Webb 66764F brake drum provides a high strength to weight ratio offering the lowest weight in its class at only 99 pounds. Webb designs, cast, and machines their brake drum in the United States.
