Description

[0001] The utility model relates to mechanical engineering, primarily transport engineering, specifically to stabilizers of lateral (transverse) stability (tilt) of railway cars, mainly passenger cars, as well as trackless vehicles (for example, trucks).

[0002] Torsion stabilizers of transverse stability (lateral tilt) of railway cars, mainly passenger cars, as well as trackless vehicles, are known, in which articulated fastening units, including units and elements (brackets, etc.) of their fastening to the car, play an important role.

[0003] Examples may include innovative solutions developed and implemented over the past 3...4 years with the direct participation of the applicant, both in relation to stabilizers in general and in terms of their components [1. RU 2770029 C1, IPC B61F 5 / 24, F16C 11 / 06, 14.04.2022; 2. RU 2743467 C1, IPC B61F 5 / 24, B60G 21 / 05, 18.02.2021; 3. RU 2763301 C1, IPC F16C 11 / 06, B61F 5 / 24, 28 / 12 / 2021; 4. RU 2777561 C1, MPK B61F 5 / 24, B60G 21 / 04, 08.08.2022, 5. RU 2788958 C1, MPK B61F 5 / 24, F16C 11 / 06. 26.01. 2023; 6. RU 135614 S, MKPO 12-17, 03 / 02 / 2023; 7. RU 2840114, IPC B61F 5 / 24, publ. 05 / 19 / 2025].

[0004] Among the foreign analog stabilizers, one can name the device according to the source of information [8. Solutions. - URL: https: / / www.ferrabyrne.co.uk / so-lutions / _(date of publication 02 / 25 / 2020, date of access 09 / 20 / 2024)].

[0005] The means of attaching the stabilizer to the parts of the car are not standardized: the specific conditions are generally not the same both in design and in terms of mounting dimensions.

[0006] In any case, each of these analogs has its own advantages and disadvantages, mostly covered in patent descriptions. Some of these are related to the adaptation of the stabilizer, including the tie rod ends, to the design of the bearing sockets. In particular, the kingpin (pin, pivot, axle) as the supporting base of the ball joint within the bearing socket also varies in design and specific dimensions. For example, there are designs with a pressed-on inner ring of the joint, and there are ball pins (the inner "spherical" ring is made integral with the pin). However, not every bearing socket is adapted to the bearing sockets: either the length of the kingpin exceeds the width of the bearing socket, or the ball pin, while removable from the bearing socket body, is larger in diameter than the mounting hole in the bearing socket bracket, and other similar issues arise.

[0007] This section discusses the development of a new stabilizer for the specified mounting locations on a railcar for "free" upper (meaning not lower, connected to the stabilizer arm ends) tie rod ends. Since the Customer's Technical Requirements are not a publicly available publication, this overview section does not contain a reference to this source.

[0008] The closest analogue (prototype) to the claimed device in terms of purpose and a set of essential design features is the tip of the traction rod of the torsion stabilizer of the transverse stability of the car body, containing a housing in the form of a body of revolution with a threaded shank for connection with the coupling rod of the traction rod, a ball joint located in the cavity of the housing with an outer ring installed in the housing, and an inner ring installed on a symmetrical kingpin, and two opposite identical flanges with sleeve parts, detachably connected to the ends of the kingpin, with the possibility of rigid installation in a socket-forming U-shaped bracket in cross-section on the frame of the body with a distance B between the mounting cheeks of the latter, central through holes in the cheeks with a diameter D and threaded holes in the cheeks for bolts for fastening the tip by means of its mentioned flanges [9. Structural and technological scheme ... - URL: https: / / ya.ru / images / search?img_url=https%3A%2F%2Fpresent5.com%2Fpresentation%2F67844941_200659688%2Fimage-32.jpg&lr=2&pos=0&rpt=simage&source=serp&text=кронстек%20 защитная%20тарского%20стабилизатора%20кронстек (Accessed 30.04.2026)].

[0009] In the prototype, the images clearly show the specific design of the socket-forming bracket for attaching the tip.

[0010] However, the prototype lacks sufficient information regarding the depicted stabilizer mounted on the car, including the internal structure of the tie rod end (primarily the bearing base of the ball joint and the joint itself) and the technology for mounting it on the car body frame bracket. Furthermore, the range of car types, specific designs, and brackets (mounting sockets) is diverse. Consequently, certain shortcomings may emerge: some technological complexity and a lack of rigidity with three degrees of freedom of the tie rod, limited layout options and limited adaptation to possible deviations in the car body frame and overall car design, and incompatibility with flanged stabilizer tie rod ends. Consequently, the prototype's technical and operational capabilities (TOC) are considered to be insufficiently high.

[0011] The problem (task) that the claimed utility model (device) is aimed at solving is to develop (design, propose) a tip (here, the upper of the two tips) of a torsion stabilizer of the transverse stability of a car body (TSPUKV), which has improved technical and operational capabilities (TOC), including adaptability to the original (specified by the Customer - the Developer of the car body frame) mounting socket-forming bracket as part of the said frame, and also expanding the range of device options in the context of a variety of designs of cars of rolling stock.

[0012] The planned technical result of use is an improvement of the TEV, including adaptability to the original (specified by the Customer - the Developer of the car body frame) mounting socket-forming bracket as part of the said frame, as well as an expansion of the range of device options in the conditions of a variety of designs of rolling stock cars.

[0013] The solution to the designated task (problem) is achieved by the fact that in the tip of the traction torsion stabilizer of the car body, containing a housing in the form of a body of revolution with a threaded shank for connection with the coupling rod of the traction rod, a ball joint located in the cavity of the housing with an outer ring installed in the housing, and an inner ring installed on a symmetrical kingpin, and two opposite identical flanges with sleeve parts, detachably connected to the ends of the kingpin, with the possibility of rigid installation in a socket-forming U-shaped bracket in cross section on the frame of the body with a distance B between the mounting cheeks of the latter, central through holes in the cheeks of diameter D and threaded holes in the cheeks for bolts for fastening the tip by means of the said flanges, according to the claimed utility model, the housing is made less than the value B, and the kingpin and the sleeve portion of the flanges are made with diameters smaller than the value D,with the possibility of their installation in a housing, previously inserted into the bracket socket between the cheeks, through the central hole of the cheek outside the socket.

[0014] The solution of the stated problem is also aimed at the particular set of essential features of the device within the framework of the main set of its features formulated in the previous paragraph and further in the formula of the invention, namely: the flanges can be made with a through hole, and the kingpin - with a threaded hole at each of its ends, with the possibility of their bolted connection with partial coverage of the kingpin by the sleeve parts of the flanges (this facilitates the installation of the tip in the limited free space between the car body and its wheel bogies, while maintaining the axial fixation of the kingpin.

[0015] Among the known devices, no devices were found whose set of essential features matches the claimed set of features. At the same time, it is precisely through the latter that a new technical result is achieved, which determines that the claimed device meets the first condition of patentability for a utility model—"world-class novelty."

[0016] The second condition for the patentability of a utility model, industrial applicability, is also indisputable and follows from the vast global experience in the design, production and operation of mechanical suspension devices in the transport industry.

[0017] The essence of the utility model (using the example of a railway car as a priority object of implementation) is disclosed in more detail in the description below, illustrated in Fig. 1, 2, where the following items are designated:

[0018] 1 - car body frame; 2 - socket-forming bracket on the car body frame; 3 - kingpin (axle) in the state removed from the body; 4 - bolts fastening flanges to the bracket cheeks; 5 and 6 - flanges for fastening the end of the TSPUKV traction rod to the bracket cheeks; 7 - body of the end (here - the upper one) of the TSPUKV traction rod; 8 - overlay support plate of the bracket; 9 and 10 - bracket cheeks; 11 - socket space of a given width B between the bracket cheeks; 12 - central coaxial holes of a given diameter D in the bracket cheeks for the sleeve parts of the flanges (flange bushings) of the end of the TSPUKV traction rod; 13 and 14 - sleeve parts of the flanges (flange bushings) of the end; 15 - through holes in the cheeks for bolts 4 (coaxial with the corresponding holes in the flanges); 16 - through holes in the bracket's overlay support plate (as an example of exclusive execution and fastening of the bracket); 17 - bolts (or studs) for fastening bracket 2 to frame 1 (as an example of exclusive execution and fastening of the bracket);18 - through hole in flanges for bolt of axial fixation of kingpin in tip; 19 - threaded holes in ends of kingpin for bolt of axial fixation of kingpin in tip; 20 - bolts of connection of flanges with kingpin; 21 - standard location of kingpin.

[0019] Fig. 1 shows a diagram (sketch) of the installation of the TSPUKV traction end on a socket-forming bracket as part of the car body frame, top view with a cross-section.

[0020] Fig. 2 - bracket with a tie rod end installed in it, side view.

[0021] The end of the torsion bar tie rod of the car body contains (see Fig. 1, 2):

[0022] housing 7 in the form of a body of revolution with a threaded shank for connection with the coupling rod of the traction rod;

[0023] a ball joint (not shown) located in the cavity of the housing 7 with an outer ring installed in the housing 7 and an inner ring installed on a symmetrical kingpin 3;

[0024] two opposite identical flanges 5, 6 with sleeve parts 13, 14 (respectively), detachably connected to the ends of the kingpin 3.

[0025] In this case, it is possible to rigidly install the tip into a socket-forming U-shaped bracket 2 in cross-section on the frame 1 of the body, with two spaced-apart parallel mounting cheeks 9, 10 and with an overlay support plate 8, with a distance B (see Fig. 1) between the mounting cheeks 9, 10 of the latter (2), central through holes 12 in the cheeks 9, 10 with a diameter D and threaded holes 15 in the cheeks 9, 10 for bolts 4 for fastening the tip by means of its flanges 5, 6.

[0026] The body 7 of the tip is made with a length less than the value B (see Fig. 1), and the pin 3 and the sleeve part 13, 14 of the flanges 5, 6 are made with diameters less than the value D, with the possibility of their installation in the body 7, previously inserted into the socket (socket space) 11 of the bracket 2 between the cheeks 9, 10, through the central opening 12 of the cheek 9 (10) from the outside of the socket 11.

[0027] In the recommended particular case (example), flanges 5, 6 are made with a through hole 18, and kingpin 3 is made with a threaded hole 19 at the ends (at each of its ends), with the possibility of their bolted connection with partial coverage of kingpin 3 by sleeve parts 13, 14 of flanges 5, 6.

[0028] The claimed device operates (is used) as follows.

[0029] As a rule (and in this example), bracket 2 with fasteners (for example, bolts 17) for fixing it on frame 1 belongs to frame 1 and is specified in the Technical Requirements of the TSPUKV manufacturer.

[0030] Since the upper end of the rod must be installed in socket 11 with the degrees of freedom provided for its operation, the end must be structurally and technologically adapted to this mounting and permit assembly and disassembly. Specifically, assembly and disassembly are permitted as operations with the end (with its threaded shank) temporarily separated from the rest of the rod.

[0031] If there is a bracket 2 on the frame 1, the corresponding tip 7 of the TSPUKV is mounted: with flanges 5, 13 and 6, 14 previously removed, as well as the extracted kingpin 3, it is inserted into the socket space 11 of the bracket 2 until all central holes are aligned, after which the kingpin 3 is inserted into its standard place 21, and then flanges 5 and 6 with their sleeve parts 13 and 14 back into the housing 7, but already outside the cheeks 9 and 10 of the bracket 2 (see Fig. 1). After which, firstly, flanges 5 and 6 are screwed to cheeks 9, 10 of the bracket with bolts 4, and secondly, pin-pin 3 is fixed in the axial direction with bolts 20 in the end threaded holes 19, thereby completing the installation of the rod end on bracket 2 and, accordingly, on frame 1 of the car body.

[0032] Due to the overall dimensions of the housing 1 along its length being less than the width (dimension) B between the cheeks 9, 10, the housing 7 is satisfactorily assembled in the socket 11. And due to the correspondence of the outer maximum diameter of the sleeve parts 13, 14 of the flanges 5 and 6 to the diameter D of the central hole in the cheeks 9 and 10, not only the kingpin 3, but also the sleeve parts 13, 14 fit into the cheeks 9 and 10 of the bracket 2.

[0033] At the same time, of course, the traction mobility necessary for the operation of the TSPUKV is maintained, and the design is quite technologically advanced.

[0034] The tip is removed from bracket 2 in the reverse order.

[0035] Thus, the combination of design features of the claimed device achieves (the presence of a cause-and-effect relationship) a technical result - an improvement in the TEV, including adaptability to the original (specified by the Customer - the Developer of the car body frame) mounting socket-forming bracket as part of the said frame, as well as an expansion of the range of device options in the context of a variety of designs of rolling stock cars.
