  • Patent number: 7481441
    Abstract: Provided is a slotted axle assembly for a vehicle suspension system. The slotted axle assembly includes an axle beam extending laterally between two axle connectors. Each axle connector is slotted for mating with an end of the axle beam. When assembled, each end of the axle beam surrounds or encapsulates an axle connector. A kingpin housing is inserted into each axle connector for receiving and retaining a king pin. Also, a bottom plate is attached to the axle beam and the two axle connectors. The slotted axle assembly may include a plurality of brackets, braces and channels, to include one or more damper brackets, air spring mating channels, and control arm brackets. Components of the slotted axle assembly may be welded together, or an alternate method of mechanical fastening may be employed.
