Embodiment Construction

[0028] exist figure 1 shows a rail wheel 2 according to the invention in a schematic side view. The rail wheel 2 comprises an annular tire 4 arranged radially on the outside. In addition, the cylindrical wheel body 6 is arranged radially on the inside. Since the tire 4 and the wheel body 6 are arranged coaxially with each other, an annular gap is formed between the tire 4 and the wheel body 6 . The spring body 10 is inserted into the annular gap. The spring body 10 is used for force transmission in the radial direction R and for torque transmission.

[0029] figure 2 is shown in a cross-sectional view along section B-B from figure 1 The track wheels 2. Therefore, the following description refers to the figure 1 and figure 2 the summary of. It has proven to be advantageous in practice if the spring body 10 is V-shaped in cross-section. In order to be able to arrange the spring body 10 between the wheel body 6 and the tire 4 , the wheel body 6 is preferably formed in...

Abstract

The invention relates to a rail wheel (2) comprising an annular wheel tyre (4), a cylindrical wheel body (6) coaxially arranged in relation to the wheel tyre (4), which wheel body has an axle hub (8), and an annular spring body (10), which extends in the radial direction (R) of the rail wheel (2) under prestress between the wheel tyre (4) and the wheel body (6) in order to support the wheel tyre (4) on the wheel body (6) in a spring-loaded manner, wherein the spring body (10) has bars (16) on at least one of the axial end sides (12, 4) thereof projecting in the axial direction (A) of the rail wheel (2), the wheel tyre (4) and / or the wheel body (6) has at least one collar (18) extending in the radial direction (R), against which collar said end sides (12, 14) of the spring body rest, wherein the or each collar (18), on the axial end side (20) thereof facing the spring body (10), has grooves (22), each of which is delimited by two contact surfaces (24) oppositely arranged in the circumferential direction (U) of the rail wheel (2), and the bars (16) grip into the grooves (22) to form a form-locking connection. The invention further relates to a rail vehicle comprising such a rail wheel (2).

Description

technical field [0001] The invention relates to a railway wheel having: an annular tire; a cylindrical wheel body arranged coaxially with the tire and having an axle hub; and an annular spring body, which is Extends under stress in a radial direction of the rail wheel between the tire and the wheel body to elastically support the tire on the wheel body. Background technique [0002] Furthermore, the invention relates to a rail vehicle having a frame serving as a chassis with at least one axle and rail wheels mounted rotatably on the axle. [0003] In principle, rail wheels are known from the prior art. For this, reference is made, for example, to the laid-open specification DE 197 43 893 A1. The rail wheel has a wheel body, a spring body and tires. The wheel body includes an axle hub, also called a wheel hub. The wheel body can be rotatably mounted on the axle with the axle hub. In addition to the axle hub, the wheel body can also have a rim ring and a wheel disk extend...
