Abstract
A one piece drum brake spider construction eliminates welds and distortion, at least relative to a typically fabricated spider, and should improve brake performance. The spider includes a main body plate having opposed flat sides, an outer perimeter, and an inner perimeter configured to receive an axle tube. Vibration control structure is preferably formed on at least one of the opposed flat sides of the main body plate, and the brake drum spider additionally includes weight minimizing features. At least the main body plate may be produced by any of a casting technique, a stamping technique, a machining technique, and an additive manufacturing technique. The invention also concerns a process of producing such a brake drum spider.
