    description
    Wheel profile.
    Technical area
    The invention relates to a wheel profile for a rail vehicle.
    State of the art
    The tuning of the wheel / rail contact has a significant impact on the handling of rail vehicles. Here are parameters such as driving stability and comfort at high speeds to optimize the sheet travel behavior and noise. Another significant parameter is the wear of the rail vehicle wheel, which can be significantly increased by an unfavorable design of this wheel / rail contact. This wear can be reduced by a low surface pressure. As a result of this surface pressure, a characteristic stress distribution arises in the participating, interacting bodies, with the maximum of the stress generally being located inside the bodies involved. As a result, a wear form can be caused by the crumbling {eng. "Spalling") is characterized by small parts of the surface structure. This phenomenon occurs at low temperatures due to the resulting embrittlement of the wheel tire metal increasingly.
    Wheel profiles according to the prior art can not meet the requirements mentioned in Russia at the same time. For example, the combination of the in Russia 1 201125736 Φ Φ # • · Φ · * * * · · • Φ Φ Φ Φ φΦ ΦΦ
    Although the common rail profile R65 with a wheel profile P8 used in Europe, adapted for Russia, satisfies smooth running at high speeds, but no acceptable wear behavior. In contrast, the wheel profile VNIIZhT-RM70 of the Russian Institute of Railways VNIIZhT offers good wear behavior in this combination, but leads to so-called "slow body motions"; Transverse vibrations of the car body, the v.a. at high speeds greatly affect the ride comfort.
    Presentation of the invention
    The invention is therefore based on the object to provide a wheel profile, which avoids the disadvantages of the prior art. In particular, it has a good running behavior at high speeds as well as good wear behavior in combination with the R65 rail profile commonly used in Russia. The wheel profile according to the invention is tuned to a determined from measurements, average worn rail profile R65 and shows in this combination the advantageous properties in particular.
    The object is achieved by a wheel profile with the features of claim 1. Advantageous embodiments are the subject of the subordinate claims.
    According to the basic idea of the invention, a wheel profile with sufficiently high equivalent conicity is described, which at the same time has a low surface pressure at the point of contact with a rail. 2 201125736 «« «··· ·································································«
    According to the invention, the wheel profile at each contact point with the rail profile has a substantially constant ratio of the curvature of the wheel profile to the curvature of the rail profile. The curvature is defined as the change in direction per run length of a sufficiently short curve piece and is assumed both in the rail profile and in the wheel profile in the plane perpendicular to the direction of travel.
    The wheel profile according to the invention is advantageously suitable for wheels of high-speed vehicles with top speeds greater than 200km / h.
    The production of the wheel profile is expediently carried out by means of wheelset lathes and can already take place during the original equipment of the rail vehicle, or an existing rail vehicle wheel can be equipped with the wheel profile according to the invention, provided that the wear limits are not exceeded. 3 201125736 • · * • • • • • • • • • • • • t * * * * * * * * * * * * * * * * * * * * * * * * * * * *.
