Description

Device for receiving and transporting at least one wheel set of a rail vehicle

Technical Field

The invention relates to a device for receiving and transporting at least one wheel set of a rail vehicle, comprising: a first side part and a second side part which are spaced apart from each other in the transverse direction, wherein the two side parts are connected to each other, wherein the two side parts each have a superstructure and a substructure, wherein the two substructures have at least one running wheel with which the device can be moved in the longitudinal direction, and wherein the two superstructures have receptacles in which wheels of a wheel set can be accommodated.

Background

Such devices are necessary, for example, to tow a rail vehicle with chassis components that have failed or are damaged.

Devices for receiving and transporting wheelsets of rail vehicles are already known from the prior art. AT 516785 Al, for example, describes a device for accommodating and transporting a wheel set. In this device, the wheels of the wheel set are accommodated in the accommodation portions of the respective side members. In order to be able to achieve a small turning radius, the wheels of the wheel set in one of the receptacles are mounted on two rollers, so that the wheels can rotate about their own axis, and the other wheel is received in the other receptacle with a horizontal play. However, no side parts with an upper structure and a lower structure that are rotatable relative to each other are provided in the apparatus.

DE 26240C discloses a device for receiving and transporting wheel sets, in which an upper structure is rotatably mounted relative to a lower structure. Two receptacles are provided on the superstructure, which receptacles can receive wheel sets of the rail vehicle. However, the device does not have separate upper and lower structures on each side, which are rotatably supported with respect to each other.

Disclosure of Invention

Against this background, the object of the invention is to design and improve the aforementioned device in such a way that the cornering travel is optimized, in particular with a small cornering radius. The object of the invention is, in particular, to provide a compact device with which small turning radii can also be driven without the device becoming derailed.

This object is achieved in an apparatus according to the preamble of claim 1 in that the upper structure of a side part is rotatably supported relative to the lower structure of the same side part.

The device according to the invention is used for receiving and transporting wheelsets of rail vehicles. The apparatus is characterized firstly by a first and a second side part. The two side parts of the device are laterally spaced apart from each other. Preferably, the two side parts are oriented substantially parallel to each other, in particular symmetrically with respect to a plane defined by the longitudinal and height directions. The distance between the two side parts is preferably selected such that the device can be moved on rails, in particular on rails having one of the rail gauges common worldwide for rail vehicles (for example a standard rail gauge). Alternatively or additionally, the device may also be arranged such that the movement of the device is enabled without tracks. This is advantageous, for example, when the device is moved on the floor of a workshop. Furthermore, the two side parts are connected to each other. The connection may be by way of rods, struts, or other members and structures. The side pieces themselves have a substructure and a superstructure, respectively. Both substructures have at least one running wheel with which the device can be moved in the longitudinal direction (i.e. in the direction of travel). For example, the running wheels are rotatably mounted in the substructure for this purpose. The combination of substructure and running wheels is also referred to as a "running carriage". Furthermore, both superstructures have receptacles in which the wheels of the wheel set can be accommodated. For this purpose, the receptacle may partially surround the wheel to be received, wherein the surrounding is preferably less than half of the circumference of the wheel. This simplifies the accommodation of the wheel set on the device. The wheels can be placed on the receptacle in its entirety or only at some points. A full placement is achieved by the shape of the receptacle corresponding to the outer geometry of the wheel to be received, whereas a placement in only some points is achieved by the shape of the receptacle differing from the outer geometry of the wheel to be received. For example, the receptacles can have different radii in the longitudinal direction as well as in the transverse direction. This has the advantage that wheels with different outer geometries can be reliably accommodated on the same accommodation.

A design of the device is characterized in that the upper structure of the side part is mounted rotatably about a rotation axis of the side part extending in the height direction. The axis of rotation may preferably be arranged approximately in the center of the respective side part. But it may alternatively be provided at other locations on the side members. By virtue of the rotatability about the vertical axis, it is achieved that the substructure can be at different steering angles relative to the superstructure and can therefore be driven particularly well through narrow turning radii.

In a further embodiment of the device, the two side parts are connected to one another by their upper structure. The connection of the two superstructures can preferably be realized here by at least one rod, in particular by two rods. Advantageously, the bars are mounted on the superstructure evenly distributed along the longitudinal direction. This allows forces and stresses to be distributed uniformly, in particular during cornering. However, the connection can also be established by means of other components, for example flat beams, plates or bar structures. By connecting the two superstructures, the device can be adapted to the wheel set accommodated by the superstructures, for example, by adjusting a defined spacing in the transverse direction.

According to a further embodiment of the device, the connection between the upper structure of the first side part and the upper structure of the second side part is rigid. The spacing between the upper structures and thus between the receptacles is thereby kept constant. This prevents the wheel sets to be accommodated from falling off the device during cornering because of the smaller or larger spacing between the accommodation sections. A further advantage of the rigid connection is the increased rigidity, as a result of which particularly heavy wheelsets can also be reliably accommodated and transported.

Another embodiment of the device provides that the two side parts are connected to one another by their understructure. The connection can be made in at least one position of the substructure, preferably in two positions of the substructure. Advantageously, the connecting portions are mounted on the substructure in a longitudinally uniformly distributed manner. This enables a uniform distribution of forces and stresses on the substructure, in particular during cornering. By the connection of the substructures, a synchronous rotation of the two substructures relative to the superstructure can be achieved. Furthermore, an adjustment of the position of the two substructures relative to each other (e.g. substantially parallel to each other) may be achieved.

A further embodiment of the device is characterized in that the connection between the lower structure of the first side part and the lower structure of the second side part is movable, in particular pivotable. The movable, in particular pivotable, design of the connection enables or significantly simplifies the steerability of the device, which contributes to an improved cornering behaviour of the device even with a small turning radius. The movable, in particular pivotable, connection can preferably be mounted in the longitudinal direction on the front end and/or the rear end of the substructure.

According to a further embodiment of the device, the connection between the lower structure of the first side part and the lower structure of the second side part is designed as a track rod. Two tie rods may also be provided. By using at least one tie rod, the steerability of the device is significantly simplified, since the steering movement on one side of the device is transmitted particularly precisely to the other side of the device. Furthermore, the tie rod allows a particularly precise adjustability of the position of the two substructures relative to one another.

According to a further embodiment of the device, the distance between the two side parts in the transverse direction can be adjusted. The adjustment of the distance may be achieved by replacing and/or removing at least a section of the connection between the side parts. Advantageously, this is achieved by means of at least one quick clamping device. Likewise, the adjustment can be effected, for example, by at least one telescopic connection between the two side parts, in particular between the two superstructures. The adjustment of the distance serves to enable the device to be used on different gauges, such as standard gauge, meter gauge, etc., which are common worldwide for rail vehicles.

Another embodiment of the device is characterized by a connection between the upper and lower structure of the same side part, which connection is formed by a projection and an undercut. By means of this embodiment, a form-fitting connection between the upper structure and the lower structure is achieved, which is particularly reliable and secure. Preferably, the connection is designed such that the projections engage in the undercuts only at the steering angles which are customary during operation (for example 10 ° per side) and no longer engage in one another at larger (less usual during operation) steering angles, so that the superstructure and the substructure can be separated.

According to a further embodiment of the device, it is provided that a sliding element is arranged between the upper and lower structure of the same side part. By means of the sliding element, the friction between the upper structure and the lower structure is reduced, which enables an easier steerability. The sliding element can be mounted on the upper structure and/or the lower structure. Preferably, the sliding element is made of metal or plastic.

According to a further embodiment of the device, the receptacle has at least one recess for fixing a rim of a wheel of the wheel set. Preferably, both superstructures have a receptacle with a recess of this type. The provision of the recess enables a defined, lateral slip-resistant position of the wheel set.

In a further embodiment of the device, it is provided that the receptacle and/or the recess are at least partially conically shaped. In this way, a particularly good adaptation to the running surface of a wheel of a rail vehicle, which is typically likewise conically shaped, is achieved. Preferably, the taper of the receiving portion/recess of the first side part is opposite to the taper of the receiving portion/recess of the second side part, so that the wheel set automatically slides by gravity into a position defined in the transverse direction when placed on the apparatus. As an alternative to the conical design, other designs of the receptacle/recess, for example a cylindrical design, can also be provided.

According to a further embodiment of the device, it is provided that at least one running wheel has a rim and/or is conically shaped. Preferably, all running wheels have a rim and/or are conically shaped. By this design of the running wheels, the equipment is optimized for running on the track by transferring the key features (conical shape, rim) of the wheels of a typical wheel set to the running wheels of the equipment.

According to a further embodiment of the device, it is provided that at least one running wheel of one side part has a steering angle of approximately the same magnitude as the running wheel of the other side part. Preferably, all the running wheels of one side part have a steering angle of substantially the same magnitude as the running wheels of the other side part. In other words, a synchronous steering movement of the running wheels of the left-hand part and of the running wheels of the right-hand part should be achieved. This can be achieved structurally, for example, by tie rods. The advantage of this solution is that even narrow turning radii can be driven through largely without jerks.

Finally, according to a further embodiment of the device, it is provided that the device is designed to be detachable and has, in particular, a quick-action locking device for tool-free mounting and/or demounting. Improved work protection is achieved by the detachable construction of the device, since the parts of the device can be carried by personnel without jeopardizing its safety or health. This can be achieved particularly well by means of a quick-locking device which is designed, for example, as a bolt with a securing device and can be fixed and released by hand without additional tools. For example, it can be provided that the two side parts can be separated from the part connecting them (e.g. coupling rod, tie rod, etc.), preferably by a quick-locking device. Alternatively or additionally, it can be provided that the running wheels can be separated from the side parts (in particular from their substructure), preferably by means of a quick-locking device.

Detailed Description

Fig. 1 shows a device 1 according to the invention for receiving and transporting at least one wheelset of a rail vehicle. The apparatus 1 comprises a first side member 2 and a second side member 2' which are spaced apart from each other in a transverse direction Y (i.e. transverse to the direction of travel F). Preferably, the two side parts 2, 2' are oriented parallel to each other. The two side parts 2, 2 ' in turn have a substructure 3, 3 ' and a superstructure 4, 4 ', respectively. The substructures 3, 3 ' and the superstructures 4, 4 ' of the same side part 2, 2 ', respectively, are rotatably supported relative to one another. The rotation takes place about a rotation axis D, D 'of the respective side part 2, 2' which extends in the height direction Z (i.e. vertically). The rotatable mounting of the substructure 3, 3 'and the superstructure 4, 4' relative to one another enables cornering travel even with small cornering radii without the risk of the wheel sets falling off the apparatus 1.

Two running

wheels

5, 5 ', 5 ", 5'" are rotatably mounted on the lower structure 3, 3 'of the two side parts 2, 2', respectively. The running

wheels

5, 5 ', 5 ", 5'" effect a movement of the device 1, in particular on rails. However, the number of running

wheels

5, 5 ', 5 ", 5 '" may also differ from the embodiment shown, for example three running

wheels

5, 5 ', 5 ", 5 '" per side member 2, 2 ', or one

running wheel

5, 5 ', 5 ", 5 '" on one side member 2, 2 ' and two running

wheels

5, 5 ', 5 ", 5 '" on the other side member 2, 2 '.

The upper structures 4, 4 'each have a receptacle 6, 6', in each of which a wheel of a wheel set can be received. The receptacles 6, 6' are adapted to the outer geometry of a typical wheel set. Preferably, the receptacles 6, 6' are shaped substantially conically, since the wheels of modern rail vehicles have a substantially conical running surface. The radius of the cone here decreases, preferably continuously, from the inside of the receptacle 6, 6 'to the outside of the receptacle 6, 6'. In the embodiment of the device 1 shown, the receptacles 6, 6 'are provided with recesses 7, 7', respectively, for supporting the rims of the wheels to be received. The recesses 7, 7 'are each arranged on the inner side of the receptacle 6, 6', wherein additional recesses can also be provided on the outer side for wheels with double rims.

The two side parts 2, 2 'are connected to each other by a connection via two superstructures 4, 4'. In the embodiment of the device 1 shown here, the connection is realized by two coupling rods 8, 8 'which are mounted on the respective inner sides of the two superstructures 4, 4'. The connection realized by the coupling rods 8, 8 ' is designed to be rigid, as a result of which the spacing between the superstructures 4, 4 ' and thus between the receptacles 6, 6 ' remains constant. The device 1 can thus be adapted to a specific track distance, for example the distance between two tracks (for example 1435 mm). Furthermore, the two substructures 3, 3 'are movably connected to one another by means of two tie rods 9, 9'. The coupling rods 8, 8 'are rigidly connected to the two upper structures 4, 4', while the tie rods 9, 9 'are hingedly connected at their two ends to the two lower structures 3, 3'. The tie rods 9, 9 'thus achieve a simplified steerability of the device 1 and are mounted on the ends of the substructure 3, 3' in the illustrated embodiment "forward" and "rearward" as viewed in the longitudinal direction X. The coupling rods 8, 8 'and the tie rods 9, 9' are preferably designed in terms of their length such that the device 1 can be moved on rails with a common track pitch by means of the running

wheels

5, 5 ', 5 ", 5'".

Fig. 2 shows a detail of the device 1 shown in fig. 1 in a top view. The areas of the device 1 that have been described in connection with fig. 1 have been provided with corresponding reference numerals in fig. 2-and in all other views. The part of the device 1 shown in fig. 2 relates to a first side part 2, but the embodiment of fig. 2 and the other figures is applied in a corresponding manner to a second side part 2' (not shown). The axis of rotation D, about which the upper structure 4 and the lower structure 3 can rotate relative to each other, is located approximately in the center of the side part 2. However, the axis of rotation D may also be located at other positions of the side part 2. In the case of a straight advance of the device 1 in the direction of the longitudinal direction X ("straight exit"), the longitudinal axis L of the superstructure 4 is oriented parallel to the longitudinal direction X and parallel to the direction of travel F. In contrast, during cornering, the longitudinal axis L of the superstructure 4 encloses a steering angle α, α' with the longitudinal direction X. The steering angles α, α' are limited on both sides in order to prevent too great a crossing between the substructure 3 and the superstructure 4. Preferably, the value of the steering angle α, α' is limited to a maximum of 15 ° per direction, in particular a maximum of 10 ° per direction. Furthermore, fig. 2 shows that the device 1 has a plurality of quick-action clamping devices S, which are designed as bolts with securing means and can be fixed and released by hand without additional tools. In this way, the device 1 can be simply disassembled. The quick-clamping device S shown in fig. 2 connects the side part 2 to the two coupling rods 8, 8 'and to the two tie rods 9, 9'.

Fig. 3 shows the device in fig. 1 in a side view along the section plane III-III drawn in fig. 2. The wheels 10 of the wheel set are schematically shown, housed in the housing 6 of the upper structure 4. The wheel set can be lifted and placed on the device 1, for example, by means of a crane. For a positive (although rotatable) connection between the substructure 3 and the superstructure 4, the substructure 3 has two undercuts 11, 11 'and the superstructure 4 has two corresponding projections 12, 12'. In the embodiment shown, they are arranged opposite one another substantially symmetrically with respect to the axis of rotation D. The undercuts 11, 11 'accommodate the respective projections 12, 12', thereby preventing the lower structure 3 from unintentionally separating from the respective upper structure 4.

Fig. 4 shows the device 1 in a side view. Between the substructure 3 and the superstructure 4, in the region of the positive connection formed by the undercuts 11, 11 'and the projections 12, 12', there is arranged in each case one sliding element 13 (visible in the enlarged view in fig. 4). By means of the sliding element 13, a simple and low-friction sliding of the two components is possible when the lower structure 3 and the upper structure 4 are moved relative to each other.

Fig. 5 shows the device 1 from fig. 1 in a side view along the section V-V drawn in fig. 4. The design of the rotatable connection between the substructure 3 and the superstructure 4 is particularly evident in the shown view, since this is a partially cut-away view. The upper structure 4 has a downwardly directed projection which is pushed into a recess provided in the lower structure 3. In order to enable low-friction rotation, a sliding bush 16 is furthermore arranged between the upper structure 4 and the lower structure 3. Engagement of the upper structure 4 and the lower structure 3 is not possible in the position shown, because the undercuts 11, 11 'and the projections 12, 12' (not shown in fig. 5) would prevent relative movement between the upper structure 4 and the lower structure 3 in the height direction Z. Thus, the engagement and disengagement of the upper structure 4 and the lower structure 3 is only possible in a significantly rotated position. It can also be seen in fig. 5 that the running wheel 5 has a substantially conical running surface 14 with a rim 15, which is discussed in more detail in connection with fig. 6.

Finally, the device 1 is shown in a front view in fig. 6. The running wheel 5 (as well as all other running wheels 5 ', 5 "') of the apparatus 1 has a conical running surface 14. The radius of the right cone preferably tapers from the inside (right side in fig. 6) to the outside (left side in fig. 6) of the side part 2'. Furthermore, a rim 15 is provided on the inner side of the running wheel 5. The rim 15 prevents the running wheels 5 from sliding out and thus prevents the device 1 from derailing when the device 1 is moving on the track. It can also be seen in fig. 6 that a further quick-action clamping device S is provided, with which the running wheel 5 "can be connected to and disconnected from the side part 2 '(in particular from its substructure 3').
