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.

A commercial vehicle wheel including a rim configured to hold a tire and a wheel disc attached to the rim with an attachment region for removable attachment to a wheel carrier. The wheel disc is formed from at least two parts, which are joined together. At least one of the parts consists of a multiphase steel alloy or a heat-treatable steel alloy.

A wheel disc adapted for use in a fabricated vehicle wheel includes a steel wheel disc defining an axis and includes a center mounting portion, an outer rim connecting flange, a plurality of radially outwardly extending spokes connecting the center mounting portion to the outer rim connecting flange and a ventilation opening provided between each pair of adjacent spokes. A width defined by a center wall of the spoke is tapered inwardly along a substantial portion of a radial length thereof as the center wall of the spoke extends generally from the center mounting portion to the outer rim connecting flange or wherein a width defined by outer walls of the spoke is tapered inwardly along a substantial portion of a radial length thereof as the outer walls of the spoke extends generally from the center mounting portion to the outer rim connecting flange.

A fabricated vehicle wheel comprises a wheel disc and a wheel rim. The wheel disc has an annular hub portion, a center hub hole in the hub portion, opposite inboard and outboard faces of the hub portion, a plurality of circumferentially spaced lug bolt holes in the hub portion, a plurality of lightener pockets in the hub portion, and an extension portion. The lug bolt holes and the lightener pockets alternate around a circumference of the hub portion. An axis extends through the hub hole. The inboard face is planar and configured to mount to a vehicle. The inboard face is perpendicular to the axis and the extension portion extends from the hub portion along the axis. The wheel rim is secured to the extension portion.

A method of assembling a vehicle road wheel includes providing a tool fixture configured to support a press-fit load and arranging on the tool fixture an isolation plate defining a plate fastener aperture and having a locating projection. The method additionally includes arranging on the isolation plate a wheel subassembly having a hub surface and an opposing fastener surface and defining a hub aperture and a wheel fastener aperture, such that the hub surface rests against the isolation plate. The method also includes aligning the hub aperture with the locating projection and the wheel fastener aperture with the plate fastener aperture. The method additionally includes installing an insert into the wheel fastener aperture and engaging the insert with the plate fastener aperture. Furthermore, the method includes applying a load to the insert to press-fit the insert into the isolation plate at the plate fastener aperture and thereby assemble the wheel.

A drive shaft is configured by joining solid stub shafts formed of a medium carbon steel to both ends of a hollow tubular body formed of a medium carbon steel. When expressed as grain size number, the grain size of the hollow tubular body at joint parts where the hollow tubular body and the solid stub shafts are joined together ranges from #5 to #9, and the grain size of the solid stub shafts at the joint parts ranges from #10 to #12.

Systems and apparatuses include a tag axle system including an axle assembly, a linkage coupling the axle assembly to a vehicle chassis, and a hydraulic cylinder coupled between the vehicle chassis and the axle assembly. The hydraulic cylinder actuates the axle assembly between a raised position and a lowered position, and acts as a spring damper suspension component.
