    • A railway wheel includes a rotation axis and a supporting disk which can be attachable on an axle at the rotation axis. The supporting disk can be coupled with a wheel rim for rolling on a rail. The wheel provides damping means of the rim with respect to the supporting disk which include elastic elements interposed between the disk and the rim, aside with respect to the median plane of the wheel. Each elastic element has its own geometrical axis and includes a first face facing the median plane of the wheel and a second face opposed thereto and facing the opposite part with respect the median plane of the wheel, so that the elastic element extends its thickness between the two faces. The first and second faces of each elastic element have the same concavity or convexity when considered in cross section in any plane containing the geometrical axis.

    • A railway wheel (10) for a vehicle comprises a rotation axis (11') and a supporting disk (11) which can be keyed or otherwise attachable on an axle at the rotation axis (11'). The supporting disk (11) can be coupled with a wheel rim (13) intended for rolling on a rail. The wheel (10) provides damping means (20) of the wheel rim (13) with respect to the supporting disk (11) which comprise a plurality of elastic elements (25) interposed between the supporting disk (11) and the wheel rim (13), aside with respect to the median plane (10') of the wheel. Each elastic element (25) has its own geometrical axis (26) and comprises a first face (25a) facing the median plane (10') of the wheel (10) and a second face (25b) opposed to the first face (25a) and facing the opposite part with respect the median plane (10* ) of the wheel, so that the elastic element (25) extends its thickness between the two faces (25a, 25b). The first face (25a) and the second face (25b) of each elastic element (25) have the same concavity or the same convexity when considered in cross section in any plane containing said geometrical axis (26). The elastic elements (25) are designed to obtain the effective damping of any stress transmitted from the wheel motion on the rail, and to increase the lifetime of the elastic element (25) itself.
    • 一种用于车辆的铁路车轮(10)包括旋转轴(11')和支撑盘(11),所述支撑盘可以在旋转轴线(11')处被键合或以其他方式附接到轴上。 支撑盘(11)可以与用于在轨道上滚动的轮缘(13)联接。 轮(10)相对于支撑盘(11)提供轮辋(13)的阻尼装置(20),其包括插入在支撑盘(11)和轮辋(11)之间的多个弹性元件(25) 13),除了相对于车轮的中间平面(10')。 每个弹性元件(25)具有其自己的几何轴线(26),并且包括面向车轮(10)的中间平面(10')的第一面(25a)和与第一面(25a)相对的第二面(25b) )并且相对于车轮的中间平面(10 *)面向相对部分,使得弹性元件(25)在两个面(25a,25b)之间延伸其厚度。 当在包含所述几何轴线(26)的任何平面中考虑横截面时,每个弹性元件(25)的第一面(25a)和第二面(25b)具有相同的凹度或相同的凸度。 弹性元件(25)被设计成获得从轨道上的车轮运动传递的任何应力的有效阻尼,并且增加弹性元件(25)本身的寿命。
