Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheel and axle technology, and in particular to a locomotive wheel and axle assembly with adaptive lubricant release. Background Technology
[0002] The locomotive wheel axle assembly is the core component of the locomotive running gear, consisting of components such as axles, wheels, bearings, and gears. The axle, as the main load-bearing component, is tightly connected to the wheel through an interference fit to form a wheelset structure, which bears the locomotive's own weight, load, and impact forces during operation. The bearings are installed in the axle box, providing rotational support for the wheelset and reducing frictional resistance. The gear transmission device enables the efficient transmission of traction motor power to the wheelset.
[0003] During long-term operation of locomotives, the gear parts of the wheel axle assembly are prone to wear and heat accumulation due to high-frequency meshing and load. Regular lubrication is required to reduce the coefficient of friction and delay component aging. However, the conventional operation mode for lubricating the gears of the wheel axle assembly still relies on the traditional manual maintenance system. That is, the locomotive needs to be driven into a professional maintenance workshop, where maintenance personnel use professional tools to perform fixed-point and quantitative lubrication under the frame. The maintenance cycle is out of sync with the actual operating conditions of the locomotive, making it difficult to perform dynamic lubrication based on the real-time wear status of the gears or the duration of operation. Utility Model Content
[0004] The purpose of this invention is to solve the problem in the prior art where the maintenance cycle of the wheel axle assembly is out of sync with the actual operating conditions of the locomotive, and it is difficult to perform dynamic lubrication based on the real-time wear status of the gears or the working time. Therefore, this invention proposes a locomotive wheel axle assembly with adaptive lubricant release.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adaptive lubricant release locomotive wheel axle assembly, including an axle and a transmission bevel gear, the transmission bevel gear being fixedly installed on the outside of the axle, a protective chamber being provided on the outside of the transmission bevel gear, and a lubricant release assembly being provided on the outside of the protective chamber, the lubricant release assembly including a lubricant delivery assembly, a release pipe, a nozzle, and a control terminal, the control terminal being signal-connected to the lubricant delivery assembly, the output end of the lubricant delivery assembly being fixedly connected to one end of the release pipe, and the other end of the release pipe being fixedly connected to one end of the nozzle.
[0006] Preferably, the lubricant delivery assembly includes a lubricant storage tank, a micro pump, and a delivery pipeline. One end of the lubricant storage tank is fixedly connected to the input end of the micro pump, the output end of the micro pump is fixedly connected to the input end of the delivery pipeline, and the output end of the delivery pipeline is fixedly connected to one end of the release pipeline.
[0007] Preferably, the release pipe extends through the outside of the protective chamber.
[0008] Preferably, a drive pipe is fixedly connected to one side of the protective chamber.
[0009] Preferably, a support base plate is fixedly connected to one side of the protective chamber, and the micro pump is fixedly installed on one side of the support base plate.
[0010] Preferably, a drain pipe is fixedly connected to the outside of the protective chamber, and a piston is fixedly connected to one end of the drain pipe.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0012] 1. In this utility model, the control terminal accurately calculates based on the built-in algorithm and sends a start command to the micro pump, which pumps the lubricating fluid in the lubricating fluid storage tank to the delivery pipeline at a stable pressure. After the directional flow of the release pipeline, the lubricating fluid is finally sprayed in a uniform mist by the nozzle, which accurately covers the working surface of the transmission bevel gear. This lubrication mechanism based on travel distance triggering breaks through the limitations of the traditional timed and quantitative lubrication mode and realizes the dynamic matching between lubrication operation and the actual wear requirements of the gear.
[0013] 2. In this utility model, when the nozzle sprays lubricating fluid onto the transmission bevel gear, some of the lubricating fluid will slide from the surface of the transmission bevel gear to the bottom of the protective chamber. Users can periodically remove the piston to drain the lubricating fluid that has accumulated at the bottom of the protective chamber through the drain pipe, thus preventing it from accumulating and oxidizing in the protective chamber for a long time, preventing contamination of surrounding mechanical parts, and ensuring the clean operation of the transmission system.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0020] 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0021] Example 1: As Figure 1 , Figure 2 and Figure 4 As shown, this utility model provides an adaptive lubricant release locomotive wheel axle assembly, including an axle 1 and a transmission bevel gear 2. The transmission bevel gear 2 is fixedly installed on the outside of the axle 1. A protective chamber 3 is provided on the outside of the transmission bevel gear 2. A lubricant release assembly 4 is provided on the outside of the protective chamber 3. The lubricant release assembly 4 includes a lubricant delivery assembly 41, a release pipe 42, a nozzle 43, and a control terminal. The control terminal is signal-connected to the lubricant delivery assembly 41. The output end of the lubricant delivery assembly 41 is fixedly connected to one end of the release pipe 42, and the other end of the release pipe 42 is fixedly connected to one end of the nozzle 43. The lubricant delivery assembly 41 includes a lubricant storage tank 411, a micro pump 412, and a delivery pipe 413. One end of the lubricant storage tank 411 is fixedly connected to the input end of the micro pump 412, the output end of the micro pump 412 is fixedly connected to the input end of the delivery pipe 413, the output end of the delivery pipe 413 is fixedly connected to one end of the release pipe 42, the release pipe 42 passes through the outside of the protective chamber 3, a drive pipe 31 is fixedly connected to one side of the protective chamber 3, a support base plate 32 is fixedly connected to one side of the protective chamber 3, and the micro pump 412 is fixedly installed on one side of the support base plate 32.
[0022] The specific settings and functions of this embodiment are described below. When the vehicle's cumulative mileage reaches a preset threshold, the control terminal accurately calculates based on its built-in algorithm and sends a start command to the micro pump 412. The micro pump 412 then starts, pumping the lubricant in the lubricant storage tank 411 to the delivery pipe 413 at a stable pressure. After being directed by the release pipe 42, the lubricant is finally sprayed in a uniform mist by the nozzle 43, precisely covering the working surface of the transmission bevel gear 2. This lubrication mechanism, triggered by driving distance, breaks through the limitations of traditional timed and quantitative lubrication modes, achieving dynamic matching between lubrication operations and the actual wear requirements of the gears.
[0023] This lubrication solution offers several significant advantages: First, it precisely matches lubrication needs, preventing excessive gear wear, abnormal noise, and efficiency loss due to insufficient lubrication, effectively extending the service life of the transmission bevel gear 2. Second, it reduces unnecessary lubrication frequency, avoiding lubricant waste and lowering maintenance costs and resource consumption. Third, the automated lubrication process significantly improves maintenance efficiency, allowing operations to be completed without manual intervention, reducing manual inspection costs and safety risks. Fourth, dynamic lubrication keeps gears in optimal working condition, helping to improve transmission system stability and optimize vehicle power transmission efficiency.
[0024] Example 2: Figures 1-3 As shown, the adaptive lubricant release locomotive wheel axle assembly of this utility model includes an axle 1 and a transmission bevel gear 2. The transmission bevel gear 2 is fixedly installed on the outside of the axle 1. A protective chamber 3 is provided on the outside of the transmission bevel gear 2. A lubricant release assembly 4 is provided on the outside of the protective chamber 3. The lubricant release assembly 4 includes a lubricant delivery assembly 41, a release pipe 42, a nozzle 43, and a control terminal. The control terminal is signal-connected to the lubricant delivery assembly 41. The output end of the lubricant delivery assembly 41 is fixedly connected to one end of the release pipe 42. The other end of the release pipe 42 is fixedly connected to one end of the nozzle 43. A drain pipe 33 is fixedly connected to the outside of the protective chamber 3. A piston 331 is fixedly connected to one end of the drain pipe 33.
[0025] The overall effect of this embodiment is that when the nozzle 43 sprays lubricant onto the transmission bevel gear 2, some of the lubricant will slide off the surface of the transmission bevel gear 2 to the bottom of the protective chamber 3. The user can periodically remove the piston 331 to discharge the lubricant that has accumulated at the bottom of the protective chamber 3 through the drain pipe 33, thus preventing it from accumulating and oxidizing in the protective chamber 3 for a long time, preventing contamination of surrounding mechanical parts, and ensuring the clean operation of the transmission system.
[0026] The device's usage and working principle are as follows: When the vehicle's cumulative mileage reaches a preset threshold, the control terminal accurately calculates based on its built-in algorithm and sends a start command to the micro pump 412. The micro pump 412 then starts, pumping the lubricant in the lubricant storage tank 411 to the delivery pipe 413 at a stable pressure. After being directed by the release pipe 42, the lubricant is finally sprayed evenly from the nozzle 43, precisely covering the working surface of the transmission bevel gear 2.
[0027] When the nozzle 43 sprays lubricant onto the transmission bevel gear 2, some of the lubricant will slide off the surface of the transmission bevel gear 2 and fall to the bottom of the protective chamber 3. The user can periodically remove the piston 331 to drain the lubricant that has accumulated at the bottom of the protective chamber 3 through the drain pipe 33.
[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
