Description

Technical Field

[0001] This application relates to the field of power technology, and in particular to a traction transformer. Background Technology

[0002] In existing locomotives, traction transformers are mostly installed on the car body using a rigid suspension connection. For example, both the mounting base of the traction transformer and the car body beam have bolt holes. The traction transformer and the car body beam are locked together by bolts passing through the bolt holes of both. In this case, the traction transformer is suspended from the car body beam by the action of the bolts.

[0003] Traction transformers and other suspension equipment are heavy and often have complex vibration sources. The vibration energy generated during operation is not easily dissipated, which can bring a certain mechanical impact to the vehicle body, exacerbate the vibration of the vehicle body, reduce the fatigue resistance of the vehicle body beams and the comfort of the vehicle. Summary of the Invention

[0004] The purpose of this application is to provide a traction transformer that can improve the installation characteristics of traction transformers and enhance the working performance and service life of the products in which the traction transformer is located.

[0005] To achieve the above objectives, this application provides a traction transformer, including a transformer body and a plurality of mounting seats disposed on the transformer body; all mounting seats are distributed around the transformer body, each mounting seat has a downwardly distributed first mounting surface for conforming to the vehicle body beam, and each mounting seat is provided with an elastic element that conforms to the first mounting surface and a fastener for passing through and locking the vehicle body beam.

[0006] In some embodiments, any first mounting surface is provided with a positioning groove into which a portion of the elastic element can be inserted.

[0007] In some embodiments, any mounting base has an upwardly distributed second mounting surface; both the first mounting surface and the second mounting surface are provided with elastic elements; fasteners pass through the first mounting surface, the second mounting surface and the two elastic elements.

[0008] In some embodiments, the transformer body includes an oil tank; the mounting base includes a first mounting portion that is fixed to the surface of the oil tank and a second mounting portion that protrudes outward from the oil tank; any mounting base includes one first mounting portion and at least two second mounting portions; the lower surface of any second mounting portion is a first mounting surface.

[0009] In some embodiments, all second mounting parts are at the same height.

[0010] In some embodiments, a U-shaped plate is provided between the first mounting part and any second mounting part.

[0011] In some embodiments, the U-shaped plate is provided with positioning holes; the positioning holes are collinear with the installation trajectory of the fasteners.

[0012] In some embodiments, the surface of the transformer body is provided with reinforcing ribs that are connected to the mounting base.

[0013] In some embodiments, the reinforcing ribs include an upper reinforcing rib located above the mounting base and a lower reinforcing rib located below the mounting base; the protrusion height of either the upper or lower reinforcing rib relative to the transformer body gradually increases toward the mounting base.

[0014] Compared with the above-mentioned background technology, the traction transformer provided in this application includes a transformer body and a plurality of mounting seats disposed on the transformer body; all mounting seats are distributed around the transformer body, each mounting seat has a first mounting surface facing downward for fitting against the vehicle body beam, and each mounting seat is provided with an elastic element that fits against the first mounting surface and a fastener for inserting and locking the vehicle body beam.

[0015] The traction transformer provided in this application uses a mounting base and its first mounting surface to support the traction transformer upwards from the vehicle body. Simultaneously, an elastic element is installed between the vehicle body beam and the first mounting surface of the mounting base, achieving elastic mounting of the traction transformer and the vehicle body. Therefore, compared to conventional traction transformers, the traction transformer provided in this application modifies a local structure, allowing the traction transformer to be suspended from and elastically connected to the vehicle body beam.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the traction transformer provided in the embodiments of this application; Figure 2 for Figure 1 Top view; Figure 3 for Figure 1 The right view.

[0024] Please refer to Figures 1 to 3 This application provides a traction transformer, including a transformer body and a plurality of mounting seats 1 disposed on the transformer body; in this embodiment, all mounting seats 1 are distributed around the transformer body, for example, all mounting seats 1 are arranged around the periphery of the transformer body; any mounting seat 1 has a downwardly distributed first mounting surface, and any mounting seat 1 is provided with an elastic element and a fastener, the elastic element is in contact with the first mounting surface of the mounting seat 1, and the fastener passes through the elastic element and the first mounting surface.

[0025] When assembling the traction transformer and the car body, the mounting base 1 of the traction transformer is connected to the body beam of the car body. Specifically, the first mounting surface of the mounting base 1 is mounted and positioned on the body beam of the car body. Of course, since the elastic element is in contact with the first mounting surface, when the first mounting surface is mounted on the body beam, the elastic element is located between the first mounting surface and the body beam. The first mounting surface and the body beam are locked and positioned by fasteners, that is, the fasteners pass through and lock the first mounting surface, the elastic element, and the body beam.

[0026] Compared with conventional traction transformers, the traction transformer provided in this application has a partially modified structure, thereby adjusting the installation method of the traction transformer and the car body. The car body beam supports the mounting seat 1 of the traction transformer upward. At the same time, an elastic element is set between the contact surface of the car body beam and the mounting seat 1 to achieve elastic installation of the traction transformer and the car body. During driving, the vibration and impact force brought to the car body by the traction transformer can be better buffered, thereby improving the fatigue resistance and comfort of the car body.

[0027] The traction transformer provided in this application will be further described below with reference to the accompanying drawings and embodiments.

[0028] In some embodiments, the first mounting surface of the mounting base 1 is provided with a positioning groove, and a portion of the structure of the elastic element can be embedded in the aforementioned positioning groove. The positioning groove constrains the relative positional relationship between the elastic element and the mounting base 1, ensuring the installation position of the elastic element between the first mounting surface and the vehicle body beam. In short, it prevents the elastic element from shifting.

[0029] In addition to the first mounting surface, the mounting base 1 usually also has an upward-facing second mounting surface, for example, see reference. Figure 3 The mounting base 1 includes a mounting plate 12 protruding outward from the transformer body. The two opposite side surfaces of the mounting plate 12 are the first mounting surface and the second mounting surface, respectively. For a mounting base 1 with a first mounting surface and a second mounting surface, one mounting base 1 can connect two elastic elements; that is, both the first mounting surface and the second mounting surface of a mounting base 1 are provided with elastic elements. Correspondingly, when fasteners are used to lock the mounting base 1 and the vehicle body beam, the fasteners pass through the first mounting surface, the second mounting surface, and the two elastic elements, and are locked to the vehicle body beam. To better constrain the installation position of the elastic elements, a positioning groove can also be provided on the surface of the second mounting surface.

[0030] In some embodiments, such as Figures 1 to 3 As shown, the transformer body of the traction transformer may include an oil tank 4, and multiple mounting seats 1 are disposed on the surface of the oil tank 4; the aforementioned mounting seat 1 includes a first mounting part that is fixed to the surface of the oil tank 4 and a second mounting part that protrudes outward from the oil tank 4. For example, the first mounting part refers to... Figure 3 The L-shaped plate 11 shown refers to the second mounting part. Figure 3 The mounting plate 12 shown is composed of an L-shaped plate 11 and a mounting base 1, which has an L-shaped cross-section. In this embodiment, any mounting base 1 may include a first mounting part and at least two second mounting parts. The lower surface of the second mounting part is also the first mounting surface of the mounting base 1. In other words, when assembling the mounting base 1 and the vehicle body beam, the second mounting part is mounted on the vehicle body beam.

[0031] The first mounting part of the mounting base 1 is attached to and fixed to the surface of the fuel tank 4, which can improve the fixed connection strength between the mounting base 1 and the fuel tank 4. One first mounting part connects to two or more second mounting parts, and multiple second mounting parts can form connection points between the fuel tank 4 and the vehicle body beam, thereby improving the installation stability of the fuel tank 4 on the vehicle body beam. At the same time, all the second mounting parts connected to the same first mounting part are relatively fixed to each other and have a definite relative positional relationship, which can simplify the product structure and improve the installation accuracy and reliability of the fuel tank 4.

[0032] Mounting seats 1 can be installed on two opposite sides of a fuel tank 4. These two mounting seats 1 form four second mounting parts around the fuel tank 4. The four first mounting surfaces of these four second mounting parts face downward and are used to fit against the vehicle body beam, thereby achieving the suspended installation of the fuel tank 4 using the vehicle body beam. Typically, all the second mounting parts of a fuel tank 4 are at the same height.

[0033] The first and second mounting parts of the mounting base 1 can be integrally formed or assembled and fixed.

[0034] Please refer to Figure 3 In some embodiments, the traction transformer provided in this application further includes a U-shaped plate 51 disposed between the first mounting part and any second mounting part; the U-shaped plate 51 is connected to both the first and second mounting parts of the same mounting base 1 to improve the structural strength of the mounting base 1.

[0035] The aforementioned U-shaped plate 51 is provided with a positioning hole 511, which is collinear with the installation trajectory of the fastener. In other words, the mounting base 1 is provided with a fastener mounting hole through which the fastener can pass, and the aforementioned positioning hole 511 is located directly above the fastener mounting hole. (See reference...) Figure 3 U-shaped plate 51 Figure 3 The U-shaped plate 51 is arranged in an inverted configuration, comprising a top plate and two side plates. Positioning holes 511 can be located on the top plate of the U-shaped plate 51. The positioning holes 511 can position fasteners during the assembly of the traction transformer and the car body, improving installation efficiency and accuracy.

[0036] In addition to the U-shaped plate 51, the traction transformer also includes a reinforcing rib 53 on the surface of the transformer body; the reinforcing rib 53 is connected to both the transformer body and the mounting base 1, and is used to reinforce and support the mounting base 1.

[0037] The aforementioned reinforcing rib 53 may include an upper reinforcing rib 531 located above the mounting base 1 and a lower reinforcing rib 532 located below the mounting base 1. The protrusion height of either the upper reinforcing rib 531 or the lower reinforcing rib 532 relative to the transformer body gradually increases towards the mounting base 1. In other words, the closer to the mounting base 1, the greater the protrusion height of the upper and lower reinforcing ribs 532 relative to the transformer body; the farther away from the mounting base 1, the smaller the protrusion height of the upper and lower reinforcing ribs 532 relative to the transformer body. Taking the upper reinforcing rib 531 as an example, the upper reinforcing rib 531 may include two parallel flanges that protrude outward from the surface of the oil tank 4, forming a U-shaped groove structure.

[0038] In summary, the traction transformer provided in this application can be suspended and installed on the vehicle body beam and elastically connected to the vehicle body beam, thereby absorbing the mechanical impact force caused by the vibration of the vehicle body during operation, reducing the impact on the vehicle body beam, improving the impact resistance and fatigue resistance of the vehicle body, and improving the comfort of the vehicle.

[0039] The traction transformer provided in this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
