A blank for an axle beam intended to support a wheel axle is formed from a continuous piece and, at its respective ends, has, on the one hand, a bushing constituting a bearing for a kingpin for supporting a wheel spindle and, on the other hand, lug-shaped protrusions on each side of the bushing, and
A blank for an axle beam intended to support a wheel axle is formed from a continuous piece and, at its respective ends, has, on the one hand, a bushing constituting a bearing for a kingpin for supporting a wheel spindle and, on the other hand, lug-shaped protrusions on each side of the bushing, and a wheel axle made from such a blank. The invention can provide a blank which is suitable both for steerable and non-steerable wheel axles for vehicles.

The invention claimed is: 1. A blank for an axle beam for supporting a wheel axle, the blank being formed in one continuous piece and having a bushing for a kingpin for supporting a wheel spindle at each end of the blank, wherein the blank has protrusions at the ends, the protrusions being situated
The invention claimed is: 1. A blank for an axle beam for supporting a wheel axle, the blank being formed in one continuous piece and having a bushing for a kingpin for supporting a wheel spindle at each end of the blank, wherein the blank has protrusions at the ends, the protrusions being situated on each side of a plane through longitudinal axes of the bushings, the protrusions each having a first part adapted to define a locking surface for the wheel spindle when the axle beam is used to support a fixed, non-steerable wheel axle, and the protrusions each having a second part adapted to define an end stop for limiting deflection of rotary motion of the wheel spindle when the axle beam is used to support a steerable wheel axle. 2. The blank as claimed in claim 1, wherein the first part of the protrusions lies farther from a midpoint of the axle beam in a longitudinal direction of the axle beam than does the second part. 3. The blank as claimed in claim 2, wherein the first part is adapted to be substantially fully machined away in order to liberate the second part when the axle beam is used to support a steerable axle. 4. The blank as claimed in claim 2, wherein the second part is adapted to be at least partially machined away in order to liberate a bearing surface for a fixing bolt in the first part, when the axle beam is used to support a fixed, non-steerable wheel axle. 5. The blank as claimed in claim 1, wherein the locking surface of the first part is placed beyond the center point, in a longitudinal direction of the axle beam, of a longitudinal axis of each bushing. 6. The blank as claimed in claim 1, wherein the second part is placed within the center point, in a longitudinal direction of the axle beam, of a longitudinal axis of each bushing. 7. The blank as claimed in claim 1, wherein the first part has a greater extent along a longitudinal axis of each bushing than does the second part. 8. The blank as claimed in claim 1, wherein the protrusions are machined to provide a locking surface, when the axle beam is used to support a fixed, non-steerable wheel axle. 9. The blank as claimed in claim 1, wherein each protrusion is a continuous piece comprising the first and second part and an intermediate piece in which the first part merges into the second part. 10. The blank as claimed in claim 1, wherein the protrusions are machined to provide deflection-limiting surfaces, when the axle beam is used to support a steerable wheel axle. 11. A wheel suspension comprising an axle beam and a wheel spindle disposed at each end of the axle beam, the wheel spindle having a kingpin mounted in a bushing of the axle beam, the wheel spindles having respective wheel axles, the axle beam being formed from a blank made in one continuous piece and having the bushings for the kingpin for supporting the wheel spindles at respective ends of the blank, wherein the blank has protrusions on each end of the blank, the protrusions being situated on each side of a plane through longitudinal axes of the bushings, the protrusions being adapted to define locking surfaces for a respective wheel spindle when the axle beam is used to support a fixed, non-steerable wheel axle, and the protrusions are being adapted to define an end stop for limiting deflection of rotary motion of the wheel spindle when the axle beam is used to support a steerable wheel axle. 12. A wheel suspension comprising an axle beam and a wheel spindle disposed at each end of the axle beam, the wheel spindle having a kingpin mounted in a bushing of the axle beam, the wheel spindles having respective wheel axles, the axle beam being formed from a blank made in one continuous piece and the bushings for the kingpin for supporting the wheel spindles at respective ends of the blank, wherein, at each end, the blank has first parts situated on each side of a plane through longitudinal axes of the bushings, the first parts being produced from protrusions and each having a locking surface for the wheel spindles of a fixed, non-steerable wheel axle. 13. The wheel suspension as claimed in claim 12, wherein locking between the wheel spindle and the axle beam is achieved by a locking surface being pressed together against a bearing surface of the wheel spindle, with an intermediate washer placed between the surfaces, by application of a clamping force via a bolt which runs through the first part and the washer, and is arranged in engagement with the wheel spindle. 14. The wheel suspension as claimed in claim 13, wherein the washer is wedge-shaped. 15. The wheel suspension as claimed in claim 14, wherein the washer has an elongated bushing running in a longitudinal direction of the wedge. 16. The wheel suspension as claimed in claim 12, wherein the wheel spindle is fixed to both of the protrusions. 17. A wheel suspension comprising an axle beam and a wheel spindle disposed at each end of the axle beam, the wheel spindle having a kingpin which is mounted in a bushing of the axle beam, the wheel spindles having respective wheel axles, the axle beam being formed from a blank made in one continuous piece and having the bushings for the kingpin for supporting the wheel spindles at respective ends of the blank, wherein the blank has, at each end, parts situated on each side of a plane through longitudinal axes of the bushings, the parts being produced from protrusions to prevent rotation of the wheel spindle about the kingpin when the axle beam is used to support a fixed, non-steerable wheel axle. 18. The wheel suspension as claimed in claim 17, wherein the wheel spindle has stop faces situated on each side of a plane through the longitudinal axes of the bushings, the stop faces being arranged so as to bear against the pails to limit rotation of the wheel spindle when the axle beam is used to support a steerable wheel axle. 19. The wheel suspension as claimed in claim 18, wherein the stop faces are formed from bolts screwed into the wheel spindle. 20. The wheel suspension as claimed in claim 17, wherein the parts are produced from the protrusions by machining away first parts. 21. A method for manufacturing an axle beam formed from a continuous, one piece blank, the blank having bushings at its ends, each bushing for a kingpin for supporting a wheel spindle, the blank having protrusions situated on each side of a plane through longitudinal axes of the bushings, the method comprising one of producing from the protrusion a first part adapted for use as a locking surface for preventing rotation of the wheel spindle about the kingpin when the axle beam is used to support a fixed, non-steerable wheel axle, and producing from the protrusion a second part adapted for use as an end stop for limiting the deflection of rotary motion of the wheel spindle when the axle beam is used to support a steerable wheel axle, wherein one of either the first part and the second part is adapted to be produced from the same blank.
