Description

Technical Field

[0001] This utility model belongs to the field of braking technology for internal combustion traction locomotives, and specifically relates to a braking assembly for an internal combustion traction locomotive chassis frame. Background Technology

[0002] A diesel locomotive is a locomotive that uses a diesel engine as its prime mover and drives the wheels to rotate through a transmission device. Based on the type of fuel used in the diesel engine, the vast majority of diesel locomotives used on Chinese railways are equipped with diesel engines. The diesel traction locomotive is able to drive the following carriages to move stably along the track. Modern diesel traction locomotives are equipped with braking components on their chassis. The braking components can lock the wheelsets of the diesel traction locomotive and brake the locomotive.

[0003] Existing braking assemblies mainly consist of brake discs and brake actuators. The brake actuators drive the brake discs, and the brake pads on the brake actuators fit against the brake discs, squeezing the brake discs to lock their position. The brake discs are directly connected to the wheelset via a drive shaft, thereby achieving braking of the wheelset. In addition, existing brake discs have heat sinks installed on the upper edge to dissipate the heat generated by the brake discs due to compression, thus assisting in the cooling of the brake discs.

[0004] Existing braking components primarily rely on heat sinks to stably cool the brake disc during use. However, this approach has certain limitations in practical applications. Specifically, the heat dissipation effect is restricted by the contact area between the heat sink and the air, making it difficult to reliably dissipate the overall temperature of the brake disc and thus affecting the actual performance of the braking components. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0007] A braking assembly for a diesel locomotive chassis includes a brake component mounted on a bogie. Wheelsets are symmetrically mounted on the bottom end of the bogie, and a brake component is mounted between the wheelsets. The brake component includes a drive shaft and a brake disc. The drive shaft is mounted between the wheelsets, and brake discs are symmetrically mounted outside the drive shaft. An air guide assembly is mounted outside the drive shaft to guide external airflow to cool the brake discs.

[0008] As a preferred embodiment of this utility model, the air guide assembly includes a mounting base, a mounting chamber, and a pushing cylinder. The mounting base is installed outside the drive shaft and on the side of the brake disc. The mounting chamber is installed at the bottom of the mounting base. The pushing cylinder is installed on the mounting chamber. A pressing and moving plate is slidably installed inside the mounting chamber. The output end of the pushing cylinder is connected to the pressing and moving plate. A rotating frame is installed at the side opening of the mounting chamber. A pressing end is installed at one end of the rotating frame, and an air guide is installed at the other end of the rotating frame. The pressing end is in pressure contact with the pressing and moving plate.

[0009] As a preferred technical solution of this utility model, the air guide includes an air guide arc plate, and an air guide is installed on the side of the rotating frame to guide external air to cool the brake disc. The air guide has an arc-shaped structure.

[0010] As a preferred embodiment of this utility model, the air guide component includes an air guide plate and a filter plate. The air guide plate is installed on the side of the rotating frame, and the filter plate that blocks impurities is installed on the air guide plate.

[0011] As a preferred technical solution of this utility model, the angle of the air guide rotates as the pressing moving plate moves, and the air guide shields and protects the area below the brake component.

[0012] As a preferred technical solution of this utility model, the brake component further includes a brake cylinder body, an extrusion frame, and brake pads. The brake cylinder body is provided on the side of the brake disc, and the extrusion frame is installed at the end of the brake cylinder body. The brake pads are installed on the extrusion frame and make extrusion contact with the side wall of the brake disc.

[0013] As a preferred embodiment of this utility model, the brake cylinder body is positioned directly above the air guide, and an air supply pipe for inputting compressed gas is installed at the end of the brake cylinder body.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The use of brake components and air guide components in this invention allows the brake disc to lock rapidly under the pressure of the brake pads, achieving overall braking of the diesel locomotive. The heat sinks within the brake disc assist in heat dissipation, lowering its temperature and facilitating repeated use within a short period. The air guide component directs airflow to cool the brake disc, accelerating the cooling process and improving its effectiveness. When not in use, the air guide component also shields and protects the brake components, preventing particles such as stones from splashing onto them and affecting their normal operation. The air guide component includes an air guide arc plate, whose structure and shape guide the airflow for precise cooling of the brake disc. It also includes an air guide plate and a filter plate. The filter plate prevents particles such as stones from entering the brake disc along its surface, ensuring the stability of the brake disc during use. Attached Figure Description

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0026] Example 1 like Figure 1 and Figure 2 As shown, this is a schematic diagram of the braking assembly of the internal combustion tractor chassis frame in this embodiment. The braking assembly in this embodiment can use the wind generated when the internal combustion tractor moves to cool down the braking assembly, accelerate the heat dissipation of the braking assembly, and enable the braking assembly to operate stably for a long time. The braking assembly includes a brake component 3 installed under the bogie 1. Multiple sets of wheelsets 2 are installed at the bottom of the bogie 1. The wheelsets 2 are connected to the brake component 3. When the brake component 3 stops rotating, the wheelsets 2 will lock up synchronously. An air guide assembly 4 is installed on the side of the brake component 3 to assist the brake component 3 in heat dissipation.

[0027] As attached Figure 3 As shown, this is a schematic diagram of the brake component 3 in this embodiment. The brake component 3 includes a drive shaft 31, a brake disc 32, and a brake cylinder 33. The drive shaft 31 is installed between the wheelsets 2 and rotates synchronously with the wheelsets 2. The brake disc 32 is symmetrically installed on the outside of the drive shaft 31. The brake cylinder 33 is provided on the side of the brake disc 32. The two ends of the brake cylinder 33 are equipped with compression frames 34. The ends of the compression frames 34 are equipped with brake pads 35 that compress the side wall of the brake disc 32. When external compressed gas enters the brake cylinder 33, the output end of the brake cylinder 33 will drive the compression frames 34 to move. At this time, the distance between the two sets of compression frames 34 is reduced. The compression frames 34 push the brake pads 35 to move closer to the brake disc 32, so that the brake pads 35 lock the rotation of the brake disc 32, thereby locking the brake disc 32 and completing the overall braking of the diesel locomotive.

[0028] It is worth noting that the brake disc 32 has grooves, and multiple sets of heat dissipation fins are installed equidistantly in the grooves. When the brake disc 32 rotates, the heat dissipation fins rotate synchronously. At this time, the heat dissipation fins help the brake disc 32 dissipate its excess heat, thereby achieving the cooling treatment of the brake disc 32. This facilitates the multiple uses of the brake disc 32 in a short period of time and extends the service life of the brake disc 32.

[0029] As attached Figure 4 and Figure 5 As shown, this is a schematic diagram of the air guide assembly 4 in this embodiment. The air guide assembly 4 includes a mounting base 41, a mounting chamber 42, a pushing cylinder 43, and a pressing and moving plate 44. The mounting base 41 is mounted on the outside of the drive shaft 31 and on the side of the brake disc 32. The mounting chamber 42 is mounted on the bottom end of the mounting base 41. The pushing cylinder 43 is mounted on the top end of the mounting chamber 42. The top end of the pushing cylinder 43 penetrates the mounting chamber 42 and enters the mounting chamber 42. The pressing and moving plate 44 is mounted on the output end of the pushing cylinder 43. The pressing and moving plate 44 slides within the mounting chamber 42. A rotating frame 45 is installed on the side wall. A pressing end 46 is installed at one end of the rotating frame 45, and an air guide 47 is installed at the other end of the rotating frame 45. When in use, the position of the pressing moving plate 44 is pushed by the operation of the cylinder 43. At this time, the pressing moving plate 44 squeezes the pressing end 46, causing the air guide 47 to rotate around the rotating frame 45 as the axis. The overall angle of the air guide 47 is adjusted, so that the air guide 47, which originally guides the air, rotates upward to shield the entire brake component 3 and prevents the stones and other particulate impurities splashed by the diesel locomotive from splashing onto the brake component 3 when it moves.

[0030] It is worth noting that when the cylinder 43 is not running, the pressing moving plate 44 does not press against the pressing end 46. At this time, the air guide 47 tilts to the bottom under the action of gravity, causing the pressing end 46 to tilt up and contact the pressing moving plate 44. At this time, the angle of the air guide 47 is initially locked. Using the structure and shape of the air guide 47 itself, the wind generated when the diesel traction locomotive moves is guided, allowing the wind to blow directly onto the brake disc 32, assisting the brake disc 32 to cool down quickly.

[0031] As attached Figure 6 As shown, it is a structural schematic diagram of the air guide 47 in this embodiment. The air guide 47 includes an air guide arc plate 471. The air guide arc plate 471 is installed on the side of the rotating frame 45. The air guide arc plate 471 has an overall arc-shaped structure. The air guide arc plate 471 guides the wind generated when the diesel traction locomotive moves to the surface of the brake disc 32 to assist the brake disc 32 in rapid cooling.

[0032] Example 2 As attached Figure 7As shown, this is a schematic diagram of the structure of the air guide 47 in this embodiment. The difference between this embodiment and embodiment 1 is that the air guide 47 includes an air guide plate 472 and a filter plate 473. The air guide plate 472 is installed on the side of the rotating frame 45. The air guide plate 472 is arc-shaped. The air guide plate 472 guides the air generated by the movement of the diesel locomotive and cools the brake disc 32. The filter plate 473 is installed on the surface of the air guide plate 472. The filter plate 473 blocks splashed stones and other impurities, preventing stones from colliding with the brake disc 32 along the surface of the air guide plate 472.

[0033] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
