摘要： A tire inflation system for a heavy-duty vehicle having a source of fluid pressure, a tire and wheel assembly, and a fluid path. The fluid path includes at least one conduit, a first valve, and a flow detection structure. The conduit provides fluid communication from the source of fluid pressure to the tire and wheel assembly. The first valve is disposed along the fluid path. The flow detection structure is disposed along the fluid path and is arranged in parallel to the first valve.

摘要： A damping air spring for heavy-duty vehicle axle/suspension systems. The damping air spring includes a piston chamber and a bellows chamber and at least one opening between the chambers to provide restricted fluid communication between the chambers. A relationship between a cross-sectional area of the at least one opening in square inches to a volume of the piston chamber in cubic inches to a volume of the bellows chamber in cubic inches to a mean effective area of the air spring in square inches or of the at least one opening in square inches to a volume of the piston chamber in cubic inches to a volume of the bellows chamber in cubic inches to a unitless ratio of the volume of the bellows chamber to the volume of the piston chamber provides damping characteristics to the air spring over a first and second critical range of frequencies.

摘要： A damping air spring for heavy-duty vehicle axle/suspension systems. The damping air spring includes a first chamber and a second chamber and at least one opening between the first chamber and second chamber to provide restricted fluid communication between the first chamber and the second chamber. An adsorptive material is disposed within the first chamber or the second chamber and works in conjunction with the at least one opening to provide damping characteristics to the air spring over a first and second critical range of frequencies.

摘要： A bushing is disclosed for pivotally mounting an end portion of an axle-supporting beam of a vehicle suspension system to a hanger bracket of the vehicle with a pair of wear pads positioned between sides of the end portion of the beam and the hanger bracket, where the pair of wear pads each has a central opening defined by an inner edge. The bushing includes a tubular body having a longitudinal axis, a first end portion, a second end portion and a beam support portion positioned between the first and second end portions. A first resilient wear pad retainer extends radially from the first end portion of the body and a second resilient wear pad retainer extends radially from the second end portion of the body. Each of the first and second wear pad retainers are configured to move into a deflected position when contacted by an inner edge of a wear pad central opening and to rebound back to an original position afterwards as the wear pad is positioned on the first or second end portions of the body so that the wear pad is secured to the bushing.

摘要： A radial mounting torque plate for mounting a disk brake component for heavy-duty vehicles, the torque plate comprising an annular portion and a pair of mounting arms. The annular portion is formed with an opening for receiving an axle of the heavy-duty vehicle. The mounting arms are integrally formed with and extend longitudinally outward in opposite directions from the annular portion and have a T-shaped cross-section.

摘要： An axle assembly includes a central tube and an axle spindle. The axle spindle is fixed to the central tube. The axle spindle has a tubular first section and a tubular second section extending from the first section. The second section has an outer diameter. The second section has a bearing support surface. A tubular transition section is located between the first section and the second section. An annular shoulder portion is formed in an axial end segment of the tubular transition section adjacent the second section. The shoulder portion has at least one annular profile located in the shoulder portion between the annular shoulder surface and the bearing support surface. The annular profile is defined by a surface with a diameter not less than the outer diameter of the second section. An antilock braking system sensor bracket locator nub is integrally formed in the tubular transition section. An antilock braking system sensor bracket engages the antilock braking system sensor bracket locator nub for proper positioning of an antilock braking system sensor.
