Description

Technical Field

[0001] The invention relates to a bogie, in particular to a method for manufacturing a modular bogie, and also to a bogie manufactured by the method for manufacturing the modular bogie. Background Art

[0002] In recent years, my country's railway industry has developed rapidly. Under the general environment of the country's vigorous promotion of the "dual carbon", "artificial intelligence" and "energy conservation and environmental protection" strategies, the demand for off-road locomotive products has gradually shifted to energy-saving, environmentally friendly, intelligent and heavy-duty types. The demand for new hybrid locomotives, pure electric locomotives and automatic driving is increasing. The off-road new locomotive market will usher in a major change. Taking the off-road steel and metallurgical industries as an example, off-road enterprises currently mainly use GK series locomotives and DF series shunting locomotives, and their emissions, energy consumption and intelligence can no longer meet customer needs.

[0003] The bogies of existing models have the disadvantages of a single installation interface and poor interchangeability of subsystems, which cannot meet the user's installation requirements for bogie subcomponents. For example, the existing locomotive bogies can usually only use rod system brakes or unit brakes for braking, and cannot achieve the purpose of interchangeable two basic brake devices on the same frame of a bogie. Therefore, it is usually necessary to design multiple frames to meet the needs of different braking methods. In addition, the wheel rim lubrication device of the existing locomotive bogie usually uses a dry wheel rim lubrication device or a wet wheel rim lubrication device to lubricate the wheel rim. However, the interfaces of the two are inconsistent and cannot be interchanged. The same frame cannot meet the user's optional requirements for the wheel rim lubrication device, that is, the wheel rim lubrication method of the existing locomotive bogie cannot take into account both dry and wet configurations. Due to the different basic braking forms and wheel rim lubrication forms, the same frame of the bogie cannot take into account a variety of different air pipelines.

[0026] The present invention provides a method for manufacturing a modular bogie, the method comprising: Figure 5 ) is provided with a mounting interface assembly for similar devices to facilitate interchangeable installation of similar devices.

[0027] In some embodiments, the method of the present invention further comprises performing the following steps on the same frame 500 of the bogie: S100, set up suitable for rod system brake device 100 (see Figure 1 ) and unit brake device 200 (see Figure 2 ) is provided with a brake device mounting interface assembly for interchangeable installation of the lever system brake device 100 and the unit brake device 200.

[0029] In some embodiments, step S100 further includes the following steps: S101. Provide an outer frame brake seat 601 and an inner frame brake seat 602 which are relatively arranged on the crossbeam 501 of the frame 500, and provide an outer rod body 701 and an inner rod body 702 which are arranged between the outer frame brake seat 601 and the inner frame brake seat 602, so that one end of the outer rod body 701 is detachably and movably connected to the outer frame brake seat 601, one end of the inner rod body 702 is detachably and movably connected to the inner frame brake seat 602, and the other end of the outer rod body 701 and the other end of the inner rod body 702 are respectively extended from the free end of the outer frame brake seat 601 and the free end of the inner frame brake seat 602, so that the rod system brake 101 of the rod system brake device 100 is detachably connected between the other end of the outer rod body 701 and the other end of the inner rod body 702 (see Figure 1 and Figure 5 ).

[0030] S102, providing an outer pad 603 and an inner pad 604, so that the outer pad 603 is arranged on the outer side surface of the outer frame brake seat 601 (see Figure 6 ), and the inner pad 604 is arranged on the outer side surface of the inner frame brake seat 602 (see Figure 7 ).

[0031] S103, provide a mounting plate 801 (see Figure 8 ), so that a portion of the mounting plate 801 is detachably connected to the outer pad 603, the outer frame brake seat 601, the inner frame brake seat 602 and the inner pad 604, and another portion of the mounting plate 801 is detachably connected to the unit brake 201 of the unit brake device 200 (see Figure 2 ).

[0032] In some embodiments, in step S101, the following dimension chain is satisfied: L3=G1+2Q1+2M1 (see Fig. 9 ). G1 is the distance between the outer side of the outer rod body 701 and the outer side of the inner rod body 702, M1 is the thickness of the outer frame brake seat 601 and the inner frame brake seat 602, Q1 is the gap between the outer rod body 701 and the outer frame brake seat 601, the inner rod body 702 and the inner frame brake seat 602, and L3 is the distance between the outer side of the outer frame brake seat 601 and the outer side of the inner frame brake seat 602.

[0033] In some embodiments, G1 includes the sum of the thickness of the outer rod 701 and the inner rod 702, and also includes the distance between the inner sides of the outer rod 701 and the inner rod 702, which is determined by the known lever brake 101 (see Figure 1) thickness. 2Q1 is 5 mm to 6.5 mm to ensure that the outer rod body 701 and the inner rod body 702 can move freely between the outer frame brake seat 601 and the inner frame brake seat 602. M1 is 15 mm to 20 mm to meet the strength requirements of the outer frame brake seat 601 and the inner frame brake seat 602.

[0034] In some embodiments, in step S102, the following dimension chain is satisfied: L=L1+L2+L3, L2=L / 2-L3 / 2+(L4-L5) (see Fig.10 ). L is the known thickness of the unit brake 201, L1 is the thickness of the outer pad 603, L2 is the thickness of the inner pad 604, L4 is the distance between the transverse center of the lever brake device 100 and the center line of the bogie, and L5 is the distance between the transverse center of the unit brake device 200 and the center line of the bogie. In the above dimension chain, L and L3 are known parameters, and L4 and L5 are determined according to the installation positions of the lever brake 101 and the unit brake 201, thereby calculating the thickness L1 of the outer pad 603 and the thickness L2 of the inner pad 604.

[0035] In some embodiments, in step S101, the following steps are also included: The first outer frame brake seat pin hole 610 and the second outer frame brake seat pin hole 611 are provided on the outer frame brake seat 601, and the first inner frame brake seat pin hole 620 and the second inner frame brake seat pin hole 621 are provided on the inner frame brake seat 602. The first outer rod body pin hole 710 is provided on one end of the outer rod body 701, and the first inner rod body pin hole 720 is provided on one end of the inner rod body 702. The first outer frame brake seat pin hole 610, the first outer rod body pin hole 710, the first inner frame brake seat pin hole 620 and the first inner rod body pin hole 720 are arranged to be concentric with each other (see Figure 6 and Figure 7 ), so that the semi-circular pin 20 passes through the above-mentioned concentric pin hole to connect the outer frame brake seat 601, the outer rod body 701, the inner rod body 702 and the inner frame brake seat 602.

[0036] like Fig.14 As shown, the distance a between the longitudinal positions and the distance b between the transverse positions of the first outer frame brake seat pin hole 610 and the second outer frame brake seat pin hole 611 need to take into account the installation space of the suspension rod 73, the suspension rod 74 and the clearance adjuster (not shown) of the lever system brake device 100. In addition, the other end of the outer rod body 701 and the other end of the inner rod body 702 are also respectively provided with pin holes for connecting the rod system brake 101, so as to fix and support the rod system brake 101. Figure 6 and Figure 7As shown, the second outer frame brake seat pin hole 611 and the second inner frame brake seat pin hole 621 are used to connect the suspension rod 73 and the suspension rod 74 of the lever system brake device 100 to the outer frame brake seat 601 and the inner frame brake seat 602 respectively.

[0037] In some embodiments, in step S102 and step S103, the following steps are also included: Four first mounting holes 901 are respectively provided on the outer pad 603, the outer frame brake seat 601, the inner frame brake seat 602, the inner pad 604 and a part of the mounting plate 801 (see Figure 6 , Figure 7 and Figure 8 ), so that the outer pad 603, the outer frame brake seat 601, the inner frame brake seat 602, the inner pad 604 and a part of the mounting plate 801 can be detachably connected by bolts through the first mounting hole 901. Three second mounting holes 902 (see Figure 2 and Figure 8 ).like Figure 8 As shown, four first mounting holes 901 are located at the upper portion of the mounting plate 801 , and three second mounting holes 902 are located at the lower portion of the mounting plate 801 .

[0038] After confirming the installation position of the unit brake 201, Fig.14 As shown, the distance d between the longitudinal positions of the four first mounting holes 901 needs to take into account the installation space from the lower cover plate (not shown) of the frame 500 and the installation space from the mounting bolts of the unit brake 201. The distance c between the lateral positions of the four first mounting holes 901 needs to be smaller than the distance of the mounting bolts of the unit brake 201 and is adjusted in combination with the bolt installation space.

[0039] After determining the thickness of the outer pad 603 and the inner pad 604 and the position of the first mounting hole 901, the outer pad 603 is designed to be 10 mm thinner than the inner pad 604 according to the installation space, welding position, and the installation positions of the semi-bright round pin 20, bolts and other fasteners. Considering the insufficient rigidity of the outer pad 603, the outer pad 603 is designed as an integrated structure. The outer pad 603 is provided with a through hole 605 surrounding the first outer frame brake seat pin hole 610 at the middle position to facilitate the semi-bright round pin 20 to pass through (see Figure 6 The thickness of the inner pad 604 is designed to be 22.5 mm, which has sufficient rigidity. Therefore, the inner pad 604 is designed to be a split structure including two pads, which is more convenient for processing and welding (see Figure 7 ).

[0040] The method for interchangeably installing the rod system brake device 100 and the unit brake device 200 is as follows: like Figure 1 , Figure 6 and Figure 7 As shown, when the lever system brake device 100 is used for braking, the semi-bright round pin 20 is sequentially passed through the first outer frame brake seat pin hole 610, the first outer rod body pin hole 710, the first inner rod body pin hole 720 and the first inner frame brake seat pin hole 620 to connect the outer frame brake seat 601, one end of the outer rod body 701, one end of the inner rod body 702 and the inner frame brake seat 602. The lever system brake 101 is connected between the other end of the outer rod body 701 and the other end of the inner rod body 702, and the suspension rod 73 and the suspension rod 74 of the lever system brake device 100 are connected to the outer frame brake seat 601 and the inner frame brake seat 602 through the second outer frame brake seat pin hole 611 and the second inner frame brake seat pin hole 621, respectively, so that the installation of the lever system brake device 100 is completed.

[0041] When the unit brake device 200 is used for braking, the semi-bright round pin 20, the outer rod body 701, the inner rod body 702 and the rod system brake device 100 are removed. Bolts are passed through the four first mounting holes 901 to sequentially connect the upper part of the mounting plate 801, the outer pad 603, the outer frame brake seat 601, the inner frame brake seat 602 and the inner pad 604. Then, the unit brake 201 is placed in a suitable position, and bolts are passed through the three second mounting holes 902 to connect the unit brake 201 to the lower part of the mounting plate 801, thereby completing the installation of the unit brake device 200.

[0042] Since the bogie is compatible with double-sided braking, the front and rear end beams 502 of the frame 500 adopt a sunken structure, and the space between the end beams 502 and the wheels is limited. The lubricating rod housing 301 of the dry wheel rim lubricating device 300 and the nozzle 401 of the wet wheel rim lubricating device 400 are allowed to be installed at a position range of 30° lower than the horizontal, which brings difficulties to the design of the seat plate 10 of the wheel rim lubricating device. After fully considering the installation and subsequent adjustment space of the device, in some embodiments, in step S200, the following steps are included: S201, provide a dry wheel rim lubrication device 300 (see Figure 3 and Fig.12 ), so that the angle α between the axial center line of the lubricating rod housing 301 of the dry wheel rim lubrication device 300 and the horizontal plane P0 of the axle is 0° to 30° (see Fig.11 ). . S202, providing a seat plate 10 (see Figure 5), so that the seat plate has an L-shaped structure and includes a vertical connection portion 11 and a horizontal connection portion 12 extending along the vertical connection portion 11 (see Fig.12 ), and the included angle between the vertical connection portion 11 and the transverse connection portion 12 is 90° minus α, wherein the dry rim lubrication device 300 is detachably and adjustably connected relative to the seat plate 10.

[0043] S203, provide a wet rim lubrication device 400 detachably and adjustably connected to the seat plate 10, so that the wet rim lubrication device 400 is configured to include a bent plate 402 and the nozzle 401 of the wet rim lubrication device 400 is arranged on the bent plate 402, so that the angle between the axial center line of the nozzle 401 and the horizontal plane P0 of the axle is 0°~30°, and the bending angle of the bent plate 402 is determined according to the angle between the vertical connecting portion 11 and the transverse connecting portion 12, the angle between the axial center line of the nozzle 401 and the horizontal plane P0 of the axle, and the spatial position between the nozzle 401 and the wheel rim.

[0044] In some embodiments, in step S201, step S202, and step S203: The angle α between the axial center line of the lubricating rod housing 301 of the dry wheel rim lubricating device 300 and the horizontal plane P0 of the axle is set to 20°±2°, and the dry wheel rim lubricating device 300 is configured to include a base 302, a lubricating rod housing 301 connected to the base 302 at an angle, and the base 302 is detachably and adjustably connected to the transverse connecting portion 12 (see Fig.12 ).like Figure 3 As shown, those skilled in the art should understand that the relative positions of the base 302 and the lubricating rod housing 301 of the dry wheel rim lubricating device 300 used by the left and right wheels are different, that is, the dry wheel rim lubricating device 300 used by the left and right wheels are set to have mutually symmetrical characteristics according to actual use. Those skilled in the art should understand that a lubricating rod core 303 for lubricating the wheel rim 60 of the wheelset is arranged in the lubricating rod housing 301, and it is obvious that the angle α between the axial center line of the lubricating rod core 303 and the horizontal plane P0 of the axle is also 20°±2°.

[0045] The included angle between the vertical connection part 11 and the horizontal connection part 12 is set to 70°±2°, and the vertical connection part 11 is set to be connected to the end beam 502 of the frame 500. In a preferred embodiment, a connection part 13 connected to the end beam 502 is set on the outer side of the vertical connection part 11.

The bending angle of the bent plate 402 can be understood as the angle between the plane where the front connecting plate 403 is located and the plane where the rear connecting plate 404 is located. Figure 4 As shown, those skilled in the art should understand that the bent plates 402 used by the left and right wheels are different only in the bending direction, and the bent plates 402 are substantially the same in terms of bending angle, structure, connection mode with the seat plate 10 and the nozzle 401, etc. That is, the bent plates 402 used by the left and right wheels are set to have mutually symmetrical characteristics according to actual usage.

The three fasteners 40 are installed in a triangle shape to make the installation structure more stable and meet the requirements of impact and vibration. Since the wheel tread may wear and the outer circle may shrink during use, the relative position between the base 302, the rear connecting plate 404 and the transverse connecting part 12 can be adjusted by the fasteners 40 and the long holes 30, so as to adjust the distance between the lubricating rod core 303, the nozzle 401 and the wheelset, so as to maintain good lubrication of the wheel rim 60 of the wheelset.

[0048] In some embodiments, in step S202 and step S203, the following steps are also included: The dimensions of the three long holes 30 are based on the newly manufactured installation position, and are calculated so that the extension amount of the lubricating rod core 303 disposed in the lubricating rod housing 301 close to the wheel end and the extension amount b1 of the nozzle 401 of the wet wheel rim lubrication device 400 both satisfy b1=R1-R2+a. The extension amount is set so that the lubricating rod core 303 or the nozzle 401 can be pushed toward the wheelset according to the wear condition of the wheelset, thereby maintaining good lubrication of the wheel rim 60 of the wheelset. Among them, R1 is the radius of the newly manufactured wheel, R2 is the radius of the fully worn wheel, and a is the gap between the end of the lubricating rod core 303 close to the wheel end and the wheel rim 60, or the gap between the nozzle 401 and the wheel rim 60 (see Fig.11). In some embodiments, for the dry wheel rim lubrication device 300, a is 0 mm. For the wet wheel rim lubrication device 400, a is 20 mm to 32 mm.

[0049] Taking into account manufacturing errors and installation space, the installation adjustment amount b2 of the lubricating rod core 303 disposed in the lubricating rod housing 301, which is away from the wheel end, is set to 15 mm to 20 mm.

[0050] The method for interchangeably installing the dry wheel rim lubricating device 300 and the wet wheel rim lubricating device 400 is as follows: when using the dry wheel rim lubricating device 300, the base 302 of the dry wheel rim lubricating device 300 is connected to the transverse connecting portion 12 of the seat plate 10, and the installation of the dry wheel rim lubricating device 300 is completed.
