Description

Technical Field

[0001] This invention relates to the field of rail transit vehicles, and in particular to a combined bracket and a combined installation structure for two dry lubricators with different functions that can be installed simultaneously. Background Technology

[0002] Wheel flange lubricator (LCF) and tread friction modifier (HPF) are important components of rail transit vehicles. LCF and HPF work by applying lubricant blocks to the wheel flange root and tread surface, respectively, forming a thin lubricating film. When the wheel flange and tread contact the rail, the lubricant is transferred to the rail. The lubricant adhering to the rail then lubricates the corresponding parts of the next wheel. This reduces dry friction between the wheels and rails throughout the train, effectively slowing down wear on the wheel flanges and treads, extending wheel life, and reducing vehicle operating and maintenance costs. Simultaneously, it significantly reduces noise generated between the wheels and rails during vehicle operation.

[0003] Existing technologies typically install only wheel flange lubricators (LCF) or only tread friction modifiers (HPF) at the ends of the frame, with wheel flange lubricators (LCF) being the most widely used. Their installation method is as follows: Figure 1 As shown, with the development of rail transit vehicle technology and the increasing diversification of customer needs, there is a real need to install two different types of lubricants simultaneously. The technical problem that needs to be solved is how to install two types of lubricants in the limited space at the end of the frame without interference between them.

[0004] On the other hand, the installation of the tread friction regulating lubricator (HPF) is often not guaranteed due to manufacturing errors, design errors, and other factors. In particular, the angle between the HPF lubricator and the inner side of the wheel cannot be adjusted, which cannot guarantee the lubrication effect of the lubricator. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a lubricator combination bracket and a lubricator combination installation structure, which can simultaneously install a wheel flange lubricator and a tread friction adjusting lubricator, and the tread friction adjusting lubricator can be adjusted to a certain angle to match the wheel to achieve a good lubrication effect.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A lubricator assembly bracket, characterized in that it includes a first bracket and a second bracket, the first bracket including a first mounting plate, a first base plate and a side plate, the first mounting plate, the first base plate and the side plate being perpendicularly connected to each other in pairs, and the side plate being provided with mounting holes;

[0008] The second bracket includes a second mounting plate and a second base plate, wherein the second mounting plate is connected to the second base plate;

[0009] The first base plate and the second base plate are rotatably connected, and the first mounting plate and the second mounting plate are respectively provided with a first waist-shaped hole and a second waist-shaped hole.

[0010] The lubricator assembly bracket of the present invention comprises a first bracket and a second bracket. The first bracket is detachably mounted on a frame via mounting holes on its side plate, and a first mounting plate is positioned towards the wheel, for mounting a rim lubricator (LCF). The second bracket is rotatably connected to the first bracket via its second base plate, and a second mounting plate of the second bracket is also positioned towards the wheel, for mounting a tread friction adjusting lubricator (HPF). Thus, the rim lubricator and the tread friction adjusting lubricator are integrated into a combined bracket consisting of the first and second brackets. Furthermore, the rotatable connection between the first and second brackets allows for adjustment of the mounting angle of the tread friction adjusting lubricator to match the wheel and achieve optimal lubrication.

[0011] According to embodiments of the present invention, the present invention can be further optimized, and the optimized technical solution is as follows:

[0012] The first base plate and the second base plate are rotatably connected by a toothed meshing structure. The toothed meshing structure enables the rotational connection between the first bracket and the second bracket, and the bracket is fixed by fasteners. This allows the tread friction adjusting lubricator installed on the second bracket to rotate within a certain range and adjust the angle to achieve a good tread lubrication effect.

[0013] Furthermore, the toothed meshing structure consists of mutually cooperating end face teeth respectively provided on the first base plate and the second base plate. The second bracket can rotate relative to the first bracket through the end face teeth and is fixed by fasteners.

[0014] Furthermore, the angle between any two adjacent teeth on the end face is 3° to 10°.

[0015] Furthermore, there are at least two first waist-shaped holes, which are arranged in parallel, and the length direction of the first waist-shaped hole is perpendicular to the axle direction; there are at least two second waist-shaped holes, which are arranged in parallel, and the length direction of the second waist-shaped hole is perpendicular to the axle direction.

[0016] Based on the same inventive concept, this invention also proposes a lubricator combination installation structure.

[0017] A lubricator assembly mounting structure includes a lubricator assembly bracket as described above. Its structural feature is that it also includes a first lubricator and a second lubricator. The first lubricator and the second lubricator each include a lubricator support tube, a lubricator mounting plate, and a lubricating block. The lubricator mounting plate is located on one side of the lubricator support tube and has a lubricator mounting slotted hole thereon. The lubricating block is located at one end of the lubricator support tube.

[0018] The first lubricator mounting slot of the first lubricator is connected to the first slot of the first bracket by fasteners;

[0019] The second lubricator mounting slot of the second lubricator is connected to the second slot of the second bracket by fasteners.

[0020] Furthermore, the direction of the first lubricator mounting hole is not the same as the direction of the first waist-shaped hole. Therefore, by adjusting the mounting position between the first lubricator mounting hole and the first waist-shaped hole, the mounting angle θ between the first lubricator and the inner side of the wheel is also adjusted.

[0021] Furthermore, the number of the first lubricator mounting holes is the same as the number of the first waist-shaped holes.

[0022] Furthermore, the angle between the first lubricator and the wheel plane is 35° to 50°.

[0023] Furthermore, the length direction of the second waist-shaped hole is perpendicular to the tangential direction of the wheel tread.

[0024] Compared with the prior art, the beneficial effects of this invention are:

[0025] 1) The lubricator combination bracket of the present invention forms a combination bracket by setting a first bracket, a second bracket and a rotary connection between them, which can integrate two lubricators with different functions and install them on the same bracket. The mounting holes of the two lubricators are set in the form of waist-shaped holes, which can adjust the installation position between the lubricator and the wheel, so that the two lubricators can be installed at a certain installation angle.

[0026] 2) The meshing structure design of the end face teeth in this invention has two advantages: first, it can adjust the installation angle of the tread friction lubricator, avoiding unreasonable angle design of the tread lubricator due to design and manufacturing errors, thus achieving a good lubrication effect; second, it reduces the use of fasteners between the first bracket and the second bracket. Through the meshing between the end face teeth and the connection of the fasteners, the installation connection between the two brackets is more secure, which is convenient for maintenance and daily inspection.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other. The terms "first," "second," and similar terms used in the present invention do not indicate any order, quantity, or importance, but are only used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word covers the element or object listed after the word and its equivalents, without excluding other elements or objects. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0046] At least one embodiment of the present invention provides a lubricator combination bracket and its mounting structure, such as Figure 2 As shown, the system includes a first bracket 1 and a second bracket 2. The first bracket 1 includes a first mounting plate 11, a first base plate 12, and a side plate 13. The first mounting plate 11, the first base plate 12, and the side plate 13 are connected perpendicularly to each other in pairs. The side plate 13 is provided with mounting holes 14, which are fixed to the frame 8 by fasteners 6. The second bracket 2 includes a second mounting plate 21 and a second base plate 22, which are connected. The first base plate 12 and the second base plate 22 are rotatably connected by a toothed meshing structure. Thus, the first bracket and the second bracket form a combined bracket, which can install two lubricators with different functions at a certain mounting angle. The first mounting plate 11 and the second mounting plate 21 are respectively provided with a first oblong hole 111 and a second oblong hole 211. The first oblong hole 111 is used to install a rim lubricator (LCF), and the second oblong hole 211 is used to install a tread friction adjusting lubricator (HPF). The rim lubricator and the tread friction adjusting lubricator are integrated on a combined bracket composed of a first bracket 1 and a second bracket 2. The rotatable connection between the first bracket 1 and the second bracket 2 allows the mounting angle of the tread friction adjusting lubricator to be adjusted to match the wheel 7 and achieve a good lubrication effect. The mounting holes of the lubricator are oblong, allowing adjustment of the mounting position between the lubricator and the wheel.

[0047] The first lubricator 4 is a rim lubricator (LCF), and the second lubricator 5 is a tread friction regulating lubricator (HPF). The function of the rim lubricator (LCF) is to lubricate the wheel rim and reduce rim wear, while the tread friction regulating lubricator (HPF) mainly acts on the wheel tread to reduce tread wear. Both the first lubricator 4 and the second lubricator 5 include lubricator support tubes 41 and 51, lubricator mounting plates 42 and 52, and lubrication blocks 43 and 53. The lubricator mounting plates 42 and 52 are located on one side of the lubricator support tubes 41 and 51, and are provided with lubricator mounting slotted holes 44 and 54. The lubrication blocks 43 and 53 are located at one end of the lubricator support tubes 41 and 51.

[0048] Combination Figures 3 to 6 The toothed meshing structure consists of mating end face teeth 3 respectively provided on the first base plate 12 and the second base plate 22. The second bracket 2 can rotate relative to the first bracket 1 through the end face teeth 3. The angle between each two adjacent teeth of the end face teeth 3 is 3° to 10°. Each rotation can adjust the angle by 3° to 10°. After rotating a certain angle, it is fixed by fasteners 6, thereby realizing the angle adjustment between the tread friction regulating lubricator (HPF) and the center of the wheel 7 to achieve the best wheel tread lubrication effect. As the wheel 7 wears down, the tread friction regulating lubricator (HPF) can also be adjusted accordingly to reduce the poor wheel tread lubrication effect caused by the wear of the wheel 7.

[0049] Combination Figure 7 The first lubricator 4's first lubricator mounting slot 44 is connected to the first bracket 1's first slot 111 via fastener 6, thereby mounting the first lubricator 4 onto the first bracket 1. The first bracket 1 has two first slots 111, arranged parallel to each other, with the length direction of the first slot 111 perpendicular to the axle direction. The number of first lubricator mounting slots 44 is the same as the number of first slots 111. The direction of the first lubricator mounting slots 44 is different from the direction of the first slots 111. By adjusting the mounting position between the first lubricator mounting slots 44 and 111, the mounting angle θ between the wheel flange lubricator (LCF) and the inner side of the wheel 7 is adjusted.

[0050] Combination Figure 8There are at least two second oblong holes 211, which are arranged in parallel. The length direction of the second oblong hole (211) is perpendicular to the axle direction. The second lubricator mounting oblong hole 54 of the second lubricator 5 is connected to the second oblong hole 211 of the second bracket 2 by a fastener 6, thereby mounting the second lubricator 5 on the second bracket 2. The length direction of the second oblong hole 211 is perpendicular to the tangent direction of the wheel 7 tread. The relative position of the second lubricator mounting oblong hole 54 and the second oblong hole 211 is adjusted by fastener 6 to adjust the relative distance between the tread friction regulating lubricator (HPF) and the wheel 7 tread.

[0051] When installing the lubricator combination mounting structure of this invention according to the design installation requirements, the first bracket 1 and the second bracket 2 are designed and manufactured in pairs. The second bracket 2 corresponding to the tread friction adjusting lubricator (HPF) is bolted to the wheel flange lubricator mounting bracket 5 using fasteners 6. The tread friction adjusting lubricator is then mounted on the second bracket 2 using the fasteners 6. Simultaneously, the mounting angle and dimensions of the tread friction adjusting lubricator relative to the wheel are adjusted using the second oblong hole on the second bracket 2. The mounting angles of the two lubricators relative to the wheel have certain requirements. To ensure better lubrication of the tread friction adjusting lubricator (HPF), it is mounted above the centerline of the wheel 7, and the angle between the first lubricator 4 and the plane of the wheel 7 is 35° to 50°.

[0052] The surfaces connecting the first bracket 1 and the second bracket 2 are designed with intermeshing end face teeth 3. This design allows for rotation of one tooth at an angle of 3° to 10° relative to the wheel 7 axis. The intermeshing design of the end face teeth 3 in this invention serves two purposes: first, it allows adjustment of the installation angle of the tread friction lubricator, preventing design and manufacturing errors from resulting in an unreasonable angle and inadequate lubrication; second, it reduces the use of fasteners between the first bracket 1 and the second bracket 2. Through the intermeshing of the end face teeth and the connection of the fasteners, the installation connection between the two brackets is more secure, facilitating maintenance and routine inspection.

[0053] The above embodiments should be understood as being used only to illustrate the present invention more clearly, and not to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art fall within the scope defined by the appended claims.
