The present invention relates to a vehicle wheel sensor apparatus and a method that determine if a vehicle wheel sensor is active or passive, while efficiently providing the necessary connectivity, power, and communication between the sensor and a controller, without requiring a change in controller hardware. For an active sensor, the apparatus provides power and receives speed signals, high frequency vibration or acceleration signals, or other analog signals. For a passive sensor, the apparatus receives speed signals.

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.

The present invention relates to an air spring lift kit that has a trailing arm with a first end portion that is pivotally connected to a hanger bracket. A horizontally oriented air bag is connected at one end to the hanger bracket and connected at another end to a pivoting lever arm. A link has one end pivotally connected to the lever arm and another end pivotally connected to a flange member that is secured to the trailing arm. A vertically oriented air bag is located between a second end portion of the trailing arm and a frame member of a vehicle, for example, a dump truck or a trailer in a tractor-trailer combination.

A combined tire inflation system and a wheel speed sensor for a vehicle steer axle has a steerable spindle with a substantially hollow interior portion. A shaft, located in the hollow interior portion, connects a rotatable hub cap adjacent the spindle and a sensor at least partially within the spindle. A magnet is secured to the shaft and rotates with the shaft. A sensor is mounted adjacent the magnet for sensing the rotation of the magnet. The shaft has a hollow interior that connects an air source with a tire associated with the hub cap.

The inventive fabricated steer axle assembly includes an axle beam, a kingpin housing, and, a fabrication connecting the axle beam and kingpin housing. The kingpin housing comprises an open-ended cylindrical tube having a groove disposed proximate each end of the tube. The fabrication includes a first end and a second end and is bent around the kingpin housing so that the first and second ends may be attached to the axle beam. A continuous weld may be used to couple the ends of the fabrication to the axle beam and secure the ends of the fabrication together along a seam extending between the kingpin housing and the beam formed after bending the fabrication around the kingpin housing.

An axle assembly is provided having a varying wall thickness resulting in an axle assembly that is lightweight yet has sufficient strength and stiffness. The axle assembly includes a tube disposed about a longitudinal axis and having first and second end portions and a center portion. The first and second end portions have a uniform wall thickness and the center portion has a wall thickness that is uniform at first and second axially spaced segments and a non-uniform wall thickness both between the axially spaced segments and between each of the axially spaced segments and the end portions.
摘要:
A vent system for a wheel hub comprising a first filtered vent at the wheel end cavity and a second vent formed by a one-way, pressure relief valve venting the axle tube to atmosphere. The vent system defines a vent path from the wheel end cavity through a first, preferably filtered, vent into the axle tube then through a second check valve connecting the axle tube to atmosphere. A porous material is positioned to cover the vent passage at the wheel end cavity for allowing a flow of gases to enter and exit the vent passage while preventing liquids and other contaminants from traveling therethrough. The porous material is held in place over the vent by a snap ring or other suitable retention system disposed within the vented plug member. The second axle tube vent is disposed along the axle tube to vent the tube itself to atmosphere with pressure relief

A trailing arm has a first side portion with an axle recess and a second side portion with an axle recess. An upper portion of the trailing arm is defined at least partially by overlapping portions of the first side portion and the second side portion. The overlapping portions define a weld aperture in the upper portion and a suspension aperture.
