Description

[0001] Safety element for a wheel of a rail vehicle

[0002] The invention relates to a locking element for a wheel of a rail vehicle, comprising a base surface and one or more bearing surfaces connected to the base surface, which extend along a longitudinal direction and are adapted to a contour of the wheel, in particular arranged at an angle to each other.

[0003] Securing elements of the type mentioned above are known from the prior art, for example as wheel chocks, rubber pads or wooden frames, to be able to store and transport wheelsets of rail vehicles in such a way that they are secured against rolling away.

[0004] However, a disadvantage of the aforementioned type of safety elements has proven to be that they are very difficult to handle.

[0005] This is where the invention comes in. The object of the invention is to provide a safety element of the type mentioned above, which is particularly easy to handle.

[0006] This problem is solved according to the invention by a locking element of the type mentioned at the outset, which has at least one permanent magnet in order to be able to magnetically attach the locking element to the wheel.

[0007] Within the scope of the invention, it was discovered that handling can be significantly simplified by connecting a permanent magnet, particularly rigidly, to the locking element. This allows the wheelset to be magnetically coupled to the locking element simply by placing it on top of the locking element. As a result, even when the wheelset is lifted, the locking elements attached to the individual wheels remain fixed and do not need to be handled or transported separately. This prevents the locking elements from unintentionally detaching from the wheels of a wheelset in a particularly simple manner.

[0008] An edge along which the contact surfaces are connected typically occupies the apex of the angle at which the contact surfaces are arranged relative to each other. This edge, or an imaginary line containing the apex, is usually oriented approximately parallel to an axis of rotation of a wheel properly positioned on the locking element. This ensures that the wheel is particularly effectively secured against rolling away in the longitudinal direction.

[0009] The locking element can be made from a wide variety of materials. For ease of manufacture and good handling, it has proven advantageous if the locking element is made at least partially from wood, rubber, and / or plastic. In particular, the locking element can be made in one piece or two pieces, resulting in simple manufacturing and a robust construction.

[0010] To effectively prevent the wheel from rolling away, it is preferably provided that the contact surfaces are arranged at an angle of 90 degrees to 175 degrees, particularly 120 degrees to 165 degrees, to each other. The contact surfaces can be designed as flat surfaces. However, it is also possible to provide only a single cylindrical or conical surface, which thus has surface sections arranged at corresponding angles to each other in order to fix the wheel longitudinally or to secure it against rolling away.

[0011] With comparatively large angles of, for example, 150 degrees to 165 degrees between the surfaces, the safety element can be compact when used for a wheel of a conventional rail vehicle, and may then have a length of only 400 mm.

[0012] Although the wheel can be secured against rolling away with just two contact surfaces arranged at an angle to each other, it is preferred that at least three flat contact surfaces be provided, arranged at angles of 170 degrees to 150 degrees to each other. A central contact surface extending along the longitudinal direction can be provided, while lateral contact surfaces adjoining the central contact surface in the longitudinal direction can each be arranged at an angle of, for example, 165 degrees to the central contact surface. Wheels of rail vehicles generally have a conical wheel profile or taper.To ensure the locking element is particularly well adapted to such wheelsets, it is preferably provided that the contact surface has an inclination at a cross-section perpendicular to the longitudinal direction, which in particular has an angle of inclination of 1 degree to 10 degrees, preferably 3 degrees to 6 degrees. The contact surfaces are thus inclined relative to the ground surface, so that when the locking element is arranged on a horizontal surface, an inclination relative to the horizontal results.

[0013] Although a multi-part design is possible, it is preferred that a support element, made primarily of wood, be provided, comprising both the one or more contact surfaces and the base. This support element is in contact with both the wheel and the ground, so any wear occurs on this support element. If the locking element has other components, wear can therefore be remedied by replacing this support element with a new one, without having to replace the entire locking element.

[0014] For easy attachment of the locking element to a wheel of a wheelset, it is preferably provided that the locking element has a side part that extends at least partially beyond the contact surfaces. The side part can then serve as a lateral stop for the wheel, thus enabling easy attachment of the locking element to the wheel.

[0015] To achieve full-surface contact between the side panel and the wheel of the wheelset, it is preferably provided that the side panel has a contact surface oriented approximately perpendicular to the base surface. Wheels of a wheelset typically have a face surface perpendicular to the axis of rotation, so that a corresponding contact surface results in full-surface contact between the wheel and the side panel. As a rule, the contact surface is perpendicular to the base surface and, when the wheel is arranged on the locking element as intended, is oriented perpendicular to one of the wheel's rotational axis. The at least one permanent magnet for magnetically attaching the locking element to the wheel can, in principle, be arranged in any position. However, it is particularly preferred that the at least one permanent magnet be arranged in the side panel.On the one hand, a flat contact surface can be easily achieved here, allowing for particularly good transmission of magnetic force. On the other hand, the side panel can also be detachably connected to the support element, so that by replacing the support element, the wear-prone contact surfaces can be replaced without requiring new permanent magnets, as the side panel can still be used.

[0016] It is particularly advantageous if the side panel has several holes spaced along its length, in which permanent magnets are arranged, so that the locking element can be magnetically connected to the wheel via the side panel. This achieves a particularly strong hold. At the same time, the magnets are then positioned in areas that are subject to no or very little wear.

[0017] It is particularly preferred that the bores are arranged on a side of the side panel facing away from the contact surface and extend to less than 50 mm, preferably less than 20 mm, and particularly less than 5 mm, from the contact surface. Thus, material of the side panel remains between the contact surface and the bore. For example, the side panel can have a wooden plate, which may be, for instance, 40 mm thick, with one side of the wooden plate forming the contact surface. On the side opposite the contact surface, bores are arranged, which, for example, have a depth of 38 mm and can accommodate the permanent magnets. Thus, a layer of approximately 2 mm of wood remains between the permanent magnet and the end face of the wheel, effectively preventing the permanent magnets from falling out on this side and ensuring good power transmission.

[0018] To reliably prevent the permanent magnets from falling out, it is preferably provided that plugs, preferably made of wood, are used to close the holes. The plugs can, for example, be fixed in the holes of the side panel by force-fit or form-fit.

[0019] For particularly easy transport of the locking element, the side panel may be provided with a handle. The handle is preferably located approximately in the center.

[0020] To facilitate the easy reconditioning of a locking element where the bearing surface and / or the base surface are damaged, it is preferably provided that the side part is plate-shaped and detachably connected to the bearing element, which has the base surface and the bearing surfaces, particularly by screw connections. The side part can be used with various bearing elements, which, for example, can be made entirely of wood and are therefore very inexpensive and easy to manufacture.

[0021] The side panel and the support element can be made of the same or different materials, for example wood or plastic.

[0022] In a set consisting of a wheelset of a rail vehicle which has two rigidly connected wheels and a locking element for securing the wheelset, it is preferably provided that the locking element is designed according to the invention.

[0023] Preferably, locking elements according to the invention are attached to both wheels of the wheelset and detachably magnetically fastened. This results in simple and safe transport as well as stable storage, whereby the wheelset is secured against rolling away. In this case, the locking elements are preferably designed to correspond to the respective wheels and, in particular, have an inclination at the contact surfaces that corresponds to the conicity of the wheels.

[0024] Further features, advantages, and effects of the invention will become apparent from the exemplary embodiments described below. In the drawings referred to herein, Figures 1 to 3 show a first exemplary embodiment of a locking element according to the invention;

[0025] Figs. 4 to 6 show a second embodiment of a locking element according to the invention;

[0026] Fig. 7 shows a locking element according to the invention in isometric view;

[0027] Fig. 8 shows a wheel of a wheelset of a rail vehicle with a safety element attached to it.

[0028] Figures 1 to 3 show a first embodiment of a locking element 1 according to the invention, wherein Figure 1 shows the locking element 1 in a front view, Figure 2 shows the locking element 1 in a side view and Figure 3 shows the locking element 1 in a top view.

[0029] As can be seen, the securing element 1 has three contact surfaces 4 extending along a longitudinal direction 5 in order to receive a wheel 2 of a rail vehicle, schematically depicted in Fig. 1, and secure it against rolling away. The illustrated securing element 1 thus has a central contact surface 4 and two adjoining lateral contact surfaces 4.

[0030] The contact surfaces 4 are arranged at angles a of 165 degrees to each other, resulting in a compact locking element 1 which secures a wheel 2 arranged on it against rolling away in longitudinal direction 5.

[0031] As can be seen in Fig. 1, the bearing surfaces 4 are also arranged at an angle β of 4 degrees, so that they are adapted to the conicity of the wheel 2. The bearing surfaces 4 thus rise towards the contact surface 14 in accordance with the conicity of the wheel 2. The inclination is shown in its true magnitude in the front view shown in Fig. 1, i.e., perpendicular to the longitudinal direction 5.

[0032] As can be seen further, the locking element 1 is essentially composed of two parts and has a support element 7, which has the bearing surfaces 4 and a base surface 3, by means of which the locking element 1 can be positioned on a substrate. A side part 8 is detachably connected to the support element 7 by screw connections, which extends laterally upwards beyond the bearing surfaces 4 and can thus establish a planar contact with an end face of the wheel 2, as can be seen in Fig. 1.

[0033] The side part 8 has bores 9 which extend from a side 10 opposite the contact surface 14 into the side part 8, parallel to an axis of rotation of the wheel 2, which is arranged on the locking element 1 as intended, but do not completely penetrate the side part 8. Permanent magnets 6 are arranged in the bores 9, by which the locking element 1 can be detachably fixed to the wheel 2. To prevent the permanent magnets 6 from falling out of the bores 9, plugs 11 are provided, by which the bores 9 can be closed. The plugs 11 can also be made of wood, plastic, or the like.

[0034] Figures 4 to 6 show a second embodiment of a locking element 1 according to the invention. Corresponding to the embodiment shown in Figures 1 to 3, Figure 4 again shows a front view, Figure 5 a side view, and Figure 6 a top view of the locking element 1. The locking elements 1 shown in Figures 1 to 3 on the one hand and Figures 4 to 6 on the other are largely identical in construction and each has a support element 7 and a side part 8. In contrast to the locking element 1 shown in Figures 1 to 3, the locking element 1 shown in Figures 4 to 6 has only two bores 9 with permanent magnets 6. However, the locking element 1 shown in Figures 4 to 6 has a handle 12 formed by a recess in the side part 8, which is arranged approximately centrally in the side part 8 in the longitudinal direction 5 in the side view.

[0035] Fig. 7 shows another locking element 1 in isometric view, which is essentially constructed the same as the locking element 1 shown in Figs. 1 to 3 and has inclined and angularly arranged contact surfaces 4 as well as permanent magnets 6 in the side part 8, which, however, are not visible in the view of Fig. 7. Fig. 8 shows a wheel 2 of a wheelset of a rail vehicle with a locking element 1 detachably attached to it. It is understood that the locking element 1 is adapted to a contour of the wheel 2, in particular with regard to its dimensions, the angles α at which the contact surfaces 4 are arranged relative to each other, and the inclination of the contact surfaces 4. Usually, a corresponding locking element 1 is also arranged on the second wheel 2 of the wheelset in order to secure the wheelset against rolling away and thus to enable safe storage and transport.

[0036] With a locking element 1 according to the invention, a wheelset of a rail vehicle can be easily secured against rolling away, whereby the locking element 1 remains attached to the wheels even when the wheelset is lifted. The preferably two-part design with a support element 7 and a side part 8 makes it easy to correct wear on the support surfaces 4 or the base surface 3 by replacing the support element 7.
