An axle housing assembly includes an axle housing that includes a center portion and a first arm portion that extends from the center portion. The axle housing assembly further includes a wheel end housing that includes a wheel end body that extends from the first arm portion and a spindle that extends from the wheel end body.

A wheel hub for a heavy-duty vehicle includes a first and second tubular hub segment. The first tubular hub segment has a first annular end surface. The second tubular hub segment has a second annular end surface and a radially extending flange. A continuous, circumferential joint is formed at the interface of the first annular end surface and second annular end surface.

With an arrangement of a bearing component on a chassis component, in particular on a wheel carrier, it is possible for a wheel of a vehicle to be mounted on the chassis component so as to be rotatable about an axis of rotation by the bearing component. The bearing component has at least one first form-fitting element disposed on the bearing component side and the chassis component has at least one first form-fitting element on the chassis component side. In order to prevent relative rotation along an orbital direction between the bearing component and the chassis component, the at least one first form-fitting element disposed on the bearing component side interacts positively with the at least one first form-fitting element disposed on the chassis component side in the assembled state along the orbital direction.

A road wheel for a tracked vehicle includes a first rim half and a second rim half operatively connected to the first rim half. The first rim half includes at least a first portion that is angled away from the second rim half. The second rim half includes at least a first portion that is angled away from the first rim half. A hollow cavity is formed between the first portion of the first rim half and the first portion of the second rim half.

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.

A thermal treatment and shot peening method for a wheel, including: heating a wheel blank to T1, and preserving the heat for t1; fast heating the wheel blank to T2, and preserving the heat for t2; performing quenching treatment, wherein a quenching medium is at temperature of T3, and the quenching transfer time is t3; performing aging treatment at aging temperature of T4, and preserving the heat for t4; performing first-stage shot peening; and performing second-stage shot peening.

Aluminum alloys described herein include silicon, iron, copper, manganese, magnesium, and chromium. In various implementations, the aluminum alloys also include one or more of zinc and titanium. Typically, a total amount of iron and manganese in the aluminum alloys is no less than 0.28% by weight and no greater than 0.45% by weight, and the grains in the aluminum alloys have an average grain length of no greater than 6 mm. Aluminum alloy billets can be forged for wheel production at selected temperatures.

A one-piece axle and a method of manufacture. The method may include providing a one-piece axle blank that has a shaft and a flange. The shaft may have a hole that may extend along an axis. The flange may extend radially outward from an end of the shaft. The shaft may be radially forged against a first mandrel to axially elongate the shaft.

A method and a device are provided for manufacturing spokes from a wire material, in particular for at least partially muscle-powered two-wheeled vehicles. The spokes include a spoke shaft having at least two shaft sections. The shaft sections differ in at least one cross-section. For shaping the cross-sections, the wire material is reshaped at least in sections by means of a shaping tool. The relative position of the wire material relative to the shaping tool is varied in the axial direction during reshaping. For shaping the cross-sections in the two shaft sections the relative position of the wire material relative to the shaping tool is varied by way of different positioning movements.

A wheel rim including a flange profile on a tire side of an open end flange of the wheel rim, the flange profile defined by the equation:

[00001]$y_1=\left(\mathrm{aTheta}.Math..Math.1+\frac{1}{{\left(1+\mathrm{Exp}\left(\mathrm{aTheta}.Math..Math.3+\mathrm{aTheta}.Math..Math.4.Math.X_1\right)\right)}^{\mathrm{aTheta}.Math..Math.5}}\right).Math.\mathrm{aTheta}.Math..Math.2$

wherein, for 0X.sub.11, aTheta1 is between 1.004 to 0.974, aTheta2 is between1.049 to 1.0182, aTheta3 is between 3.601 to 2.760, aTheta4 is between 18.791 to 25.965, and aTheta5 is between 0.185 to 0.277.
