Abstract
An integrated axle spindle and brake spider assembly for axles of heavy duty vehicles such as trucks, and trailer axles. The assembly is a one-piece member comprising a cylindrical hollow axle spindle and a brake spider extending radially outwardly from the axle spindle. The brake spider includes an actuator support plate provided with a support opening for a brake actuator cam shaft, and a pivoting end support plate provided with a pair of pivot pin bores receiving brake shoe supporting pivot pins. The integrated axle spindle and brake spider assembly is manufactured from a single steel alloy billet as a one-piece forging. The one-piece assembly reduces the overall weight of the component, cost of manufacturing, and improves positioning accuracy of brake components and structural integrity.
