摘要： The invention is directed to a rotor of a disc brake system for heavy-duty vehicles. The rotor includes an inboard disc and an outboard disc. The outboard disc is spaced apart from the inboard disc, and a plurality of pins extends between and rigidly connects the inboard disc and the outboard disc. A sleeve includes an inboard end and an outboard end, and is disposed inside an inner perimeter of the outboard disc. A connecting member extends between and rigidly connects an inner perimeter of the inboard disc to the inboard end of the sleeve. The inboard disc attachment to the sleeve and the interconnecting pins cooperate to improve the resistance of the rotor to thermal stress created during braking, thereby increasing the performance and the life of the rotor.

摘要： A wheel end assembly for a heavy-duty vehicle includes an axle spindle and a hub rotatably mounted on the axle spindle. A main seal extends radially between the axle spindle and the hub. The seal includes a dynamic portion that seats in a bore formed in the wheel hub, and a static portion that seats on the axle spindle. The static portion includes a rigid carrier that in turn includes a first member, and a second member that is rigidly attached to the first member. An elastomer is bonded to the carrier member and forms a first external lip. The first external lip extends generally parallel to a chamfer formed in an inboard end of the hub. The first external lip, other external features, and internal features prevent contaminants from entering the wheel end assembly, retain lubricant in the assembly, and provide a dynamic expulsion surface to expel contaminants.

摘要： An outboard sealing system cooperates with components of a heavy-duty vehicle wheel end assembly to retain lubricant in the assembly. The sealing system includes a seal that is disposed axially between an outboard bearing and a hubcap of a wheel end assembly. The seal also extends radially between an axle spindle nut and a surface of a bore formed in the hub of the wheel end assembly. The seal forms a barrier between the outboard bearing and the hubcap to reduce a flow of lubricant from a hub cavity into the hubcap. The sealing system retains lubricant in the wheel end assembly, prevents contaminants from entering the wheel end assembly, and retains the relative position of the outboard bearing in the hub during servicing. The sealing system preferably includes an additional barrier that reduces corrosion at the interface of the hubcap and an outboard face of the hub.

摘要： Self-steering axle assembly (22a, 22b) has an axle (48) with central tube having a longitudinal central axis. A king pin (62a) is connected with an end portion of the axle (48). A knuckle (24a) is connected with the king pin (62a). The knuckle (24a) includes a torque plate section (66a). A first arm (100) of the knuckle (24a) extends from a side of the torque plate section (66a) and receives a first end portion of the king pin (62a). A second arm (102) extends from the torque plate section (66a) in the same direction as the first arm (100). The second arm (102) receives a second end portion of the king pin (62a). A spindle (64a) is friction-welded to the torque plate section (66a) and has a longitudinal central axis. The torque plate section (66a) has at least one surface (80a) on the torque plate section (66a) extending substantially perpendicular to the longitudinal central axis of the spindle (64a). A tool engages the surface during friction welding of the spindle (64a) to the torque plate section (66a). The relative locations of the axle (48), spindle (64a) and king pin (62a) enable an air disc brake actuator (180) to avoid contact with components of the heavy-duty vehicle during steering and with the ground and debris.
