  • the invention relates to a shaft for a vehicle, comprising a shaft and at least one integrally formed on the shaft flange. Furthermore, the invention also relates to a method for producing the aforementioned shaft.
  • the shaft is designed in a lightweight construction.
  • Shafts having a shank and at least one flange are typically made of a flange member and a shank member which are axially connected to one another.
  • the disadvantage of this is the connection point between the shaft and the at least one flange.
  • one-piece shafts are known, which are formed from a shank and at least one flange, which are produced by turning or forging.
  • a disadvantage of a shaft produced by turning is the high material removal and disadvantageous in a shaft produced by forging is the high energy consumption.
  • DE 20 58 016 A1 discloses a multi-layered shaft with at least one integrally formed flange. Both the shaft portion and the flange portion are formed concentrically about an axis. A first number of layers are arranged concentrically with each other, wherein the first number of layers extend over the entire length of the shaft portion and the flange portion and are glued together.

  • the shaft can also be used in a wheel drive or a steering arrangement of the vehicle.
  • the shaft or flange shaft can be formed either from a metallic material or a fiber-plastic composite. Decisive is the one-piece design of the at least one flange with the shaft. If the shaft is made of a metallic material, in particular of a steel material or of a light metal, two halves are joined together. The two halves are identical and each have at least one flange which is formed integrally with the shaft. The two halves can be joined materially, in particular welded or glued. Characteristic of the shaft, which is formed from the two metallic halves, are two longitudinal seams that extend over the entire axial length of the shaft. If the shaft is formed from the fiber-plastic composite, the shaft is formed in one piece. Preferably, the shaft is designed as a hollow shaft.
  • the integral design of the flange shaft according to the invention enables a higher productivity and at the same time a cost reduction in the production.
  • Flange shaft is self-reinforced and has high rigidity and low stresses under load.
  • the flange shaft is designed in lightweight construction.
  • the shaft is made of a thermoplastic fiber-reinforced plastic composite.
  • the shaft is made of a resin preimpregnated thread, a so-called prepreg.

Consequently, a plurality of ribs extend in the radial direction, which serve as the respective support and connecting member between the flange and the shaft. Preferably, the ribs are evenly distributed around the circumference. In particular, six ribs are provided, but also several or fewer ribs can be provided. Between two ribs, a bore is preferably provided on the flange. According to a further preferred embodiment, recesses for bores are provided on a one-piece transition between the at least one flange and the shaft.
  • the flange has a reinforcing structure, which is provided in particular for an increased torque load, wherein recesses are provided in the reinforcing structure on the flange for simplified passage and fastening of screws in bores provided for this purpose on the flange.
  • a web portion is formed tangentially between two recesses.
  • the inventive method for producing the shaft according to the invention comprises in particular the following method steps.
  • First, the production of a shaft blank takes place either from two metallic halves, which are connected to one another along a longitudinal axis, or in one piece from a fiber-plastic composite.
