The invention relates to a component in the form of a wheel comprising: a hub portion, a rim portion with an outer rim flange and an inner rim flange, a plurality of circumferentially distributed spokes extending between the hub portion and the rim portion, wherein the spokes and the hub portion are arranged offset with respect to a wheel center plane towards the outer rim flange and have an inner side facing the wheel center plane and an outer side directed away from the wheel center plane, wherein the outer rim flange has greater tensile residual stresses at least in a partial region than at least a partial region of the inner rim flange.

A device for quenching a wheel includes at least one hub outer cooling unit for quenching the outer side of a hub portion of the wheel; at least one hub inner cooling unit for quenching the inner side of the hub portion; at least one spoke outer cooling unit for quenching outer sides of the spokes, and at least one rim cooling unit for quenching the rim portion. The cooling units are each configured to spray a cooling medium onto the wheel and are independently controllable by a control unit.

A portal axle as well as a method for manufacturing a portal axle for a rail vehicle, which has an axle centre part extending along a longitudinal axis and two kingpins, one of which sits on a first end section of the axle centre part and a second on a second end section of the axle centre part formed opposite to the first end section. The kingpins are oriented away from the axle centre part and form an axis of rotation in use for a rail wheel rotatably mounted on the respective kingpin. The portal axle has optimised usage properties with minimised weight. This is achieved by a longitudinal opening extending in the longitudinal direction of the portal axle being formed in at least one of the mould components. The invention further provides a method for manufacturing an axle of this type.
