摘要： A slack adjuster assembly for heavy-duty vehicles, the slack adjuster assembly comprising a slack adjuster and an inboard sealing assembly. The slack adjuster is disposed about and has an internal spline for receiving an external spline of an inboard end of a camshaft of a camshaft assembly of the heavy-duty vehicle. The internal spline has a radial clearance from the external spline. The inboard sealing assembly includes mechanical components that cooperate with the radial clearance to increase grease flow and distribution. The inboard sealing assembly is disposed over the inboard end of the camshaft and engages an inboard side of the slack adjuster to form a 360-degree seal about the inboard side.

摘要： Tone ring mounting structure for an antilock braking system comprising a wheel end assembly rotatable component having at least a first end surface and a first engagement mechanism extending radially and non-cantilevered from the rotatable component, and a tone ring having a second end surface and a second engagement mechanism extending radially from the tone ring. Connecting engagement of the first engagement mechanism of the wheel end assembly rotatable component and the second engagement mechanism of the tone ring affects movement of the second end surface in a direction toward the first end surface. The first engagement mechanism and the second engagement mechanism can be engageable threads. The first engagement mechanism can include lugs formed on the wheel end assembly rotatable component and the second engagement mechanism threads or wedge ramps engageable with the lugs. A corrosion resistant coating can be applied to components of the tone ring mounting structure.

摘要： An axle-to-beam connection for a suspension assembly of an axle/suspension system of a heavy-duty vehicle including an axle, a beam, and a top pad. The beam includes an alignment assembly for aligning the axle with the beam. The top pad includes an integrally-formed bump stop boss and is fixedly attached to the axle and removably attached to the alignment assembly of the beam.

摘要： A hub for a heavy-duty vehicle and for mounting a wheel for relative rotation comprises a substantially cylindrical body having axially opposite end portions and a longitudinal central axis. Each of a pair of bearing receiving bores is formed in the cylindrical body at a respective axially opposite end portion of the cylindrical body. A circumferential envelope has an outer diameter and is formed on the cylindrical body about one of the pair of bearing receiving bores. A flange extends radially outward from the cylindrical body at a location between the pair of bearing receiving bores. A barrel portion of the cylindrical body extends between the flange and the circumferential envelope and has an outer diameter. The hub provides sufficient strength and minimizes weight by incorporating specific longitudinal profiles and ratios and/or relationships of various dimensions of the barrel portion 104.

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

摘要： A bushing for use in an axle/suspension system of a heavy-duty vehicle. A beam supports an axle for pivotal movement with a hanger of the heavy-duty vehicle at a pivot connection. A bumper is fixed to the beam and contacts an engagement member of the heavy-duty vehicle to limit the relative pivotal movement of the beam and axle in one direction. A force is applied to the pivot connection in a force application direction that is angularly spaced from horizontal and vertical planes. The pivot connection includes a bushing to connect the beam and the hanger. The bushing includes an elastomeric bushing body with at least one void for decreasing rigidity of the bushing body in a substantially vertical direction. The one void is located in the bushing body angularly spaced from the force application direction. The bushing body is substantially solid along the force application direction.
