Problems solved by technology

Here, the structure is particularly complex and a quintic (parabolic) function is used for the structure of the transition
This is very complex in terms of constructional design on the one hand and programming in production on the other hand

Embodiment Construction

[0029] The side view of the wheel 1 can be seen purely by way of example in the illustration in FIG. 1. Such a wheel 1 is used as a wheel for rail vehicles. The structure is shown in detail by the section marked II-II in FIG. 1 which can be seen in FIG. 2. The structure shown in FIG. 2 can be used purely for illustrating the elements of the roulette here. The structure according to the present invention will later be used Figure 4 Will also elaborate. It can be seen in the radial section of FIG. 2 that the wheel disc 1 is composed of a hub 3 surrounding the axis of rotation 2. The hub 3 is connected via disc-shaped members called spokes 4 to a rim 5 that rolls on a track when the wheel 1 is used. This structure as it is shown in FIG. 2 is generally known and common. The illustration in FIG. 2 is a structure with so-called straight spokes 4 extending perpendicular to the axis of rotation 2 in the radial direction.

[0030] Instead of such straight spokes 4, other structures...

Abstract

The invention concerns a wheel disc for a rail vehicle, comprising: a wheel hub surrounding a rotary shaft; a wheel flange; and a web connecting the wheel hub to the wheel flange. The invention is characterized in that a transition curve between the web and the wheel hub and / or a transition curve between the web and the wheel flange is / are formed on at least one axial side in each radial cutting plane such that the transition curve is formed by a Bezier curve, the Bezier curve merging at a constant tangent into the contour of the web and merging at a constant tangent into the contour of the wheel hub or of the wheel flange.

Description

Technical field [0001] The invention relates to a wheel used for rail vehicles. Background technique [0002] Wheel disks for rail vehicles are known from the general prior art. They typically consist of a hub that runs around the axis of rotation and a rim dedicated to rolling on the track. The hub in the middle and the rim on the outer circumference are connected to each other via so-called spokes. The spokes implemented straight, obliquely or curvedly in the radial direction are typically configured as circumferential disks. In particular, the spokes can be constructed rotationally symmetrically to a large extent and therefore have the same or similar contours in each radial section. In the sense of the present invention, a profile can be understood here as the surface shape of the wheel disc laterally defined in a radial section. Therefore, a straight wheel has a contour formed by a straight line, and a curved wheel has a contour formed by an S-shaped or C-shaped arc. [0...
