    • A hub (2) includes a spindle (14) which projects through a housing (4) and rotates relative to the housing (4) on a bearing (6) that is located between the spindle (14) and the housing (4). The bearing (6) has two sets of raceways (28, 40) that are oblique to the axis x, and in addition rolling elements (36) arranged in two rows between the sets of raceways (28, 40). The inner raceways (28) that fit around the spindle (14) and have back faces (32), with the back face (32) for one of the races (26) being against a shoulder (18) from which the spindle (14) projects. Initially, the end of the spindle (14) projects straight beyond the back face (32) of the outer race - indeed, so that the races (26) can be installed over the spindle (14). But once the housing (4) and races (26) are in a position around the spindle (14), the projecting end portion of the spindle (14) is deformed radially and axially in a rotary forming operation such that it transforms into a formed end (20) that lies behind back face (32) of the race (26). With the two races (26) between the formed end (20) and the shoulder (18). During the rotary forming operation the hub (26) rotates, and the end of its spindle (14) is forced against a rotating forming tool and the force is monitored. The housing (4) is restrained and the torque transferred from the rotating hub (2) to the housing (4) is monitored.

    • The present invention relates to a method for designing a traction unit for a rail vehicle, the traction unit (103, 108) comprising at least one wheel unit (105) connected to a drive unit (107) driving the at least one wheel unit (105). The method comprises, in a press fit evaluation step, evaluating a press fit acting between a wheel and a shaft (105.1) of the wheel unit (105) for compliance with at least one press fit integrity criterion, the press fit acting between a first press fit section (105.4) of the wheel (105.2) and a second press fit section (105.5) of the shaft (105.1), an axis of rotation of the shaft (105.1) defining an axial direction of the wheel unit (105) and a torsional direction about the axis of rotation. The press fit evaluation step comprises a press fit modeling part, wherein the press fit is modeled by splitting the second press fit section (105.5) into a plurality of press fit segments (105.6) along the axial direction, linking each of the press fit segments (105.6) to an adjacent press fit segment (105.6) in the torsional direction using a first linking characteristic and in the axial direction using a second linking characteristic, and linking each of the press fit segments (105.6) to an adjacent part of the first press fit section (105.4) of the wheel (105.2) via at least one frictional third linking characteristic. The press fit evaluation step comprises a press fit simulation part, wherein the modeled press fit is subject to at least one predefined load to evaluate compliance of the press fit with the at least one press fit integrity criterion.
