Description

Technical Field

[0001] This utility model belongs to the technical field of wet brakes, specifically a wet brake cooling and lubrication mechanism. Background Technology

[0002] Wet brakes, with their significant advantages such as smooth braking, low wear, and long service life, are widely used in heavy-duty operations such as construction machinery, mining machinery, and heavy vehicles. During the operation of a wet brake, the brake friction pairs generate a large amount of heat due to intense friction. The lubrication condition of these friction pairs directly affects braking efficiency and component lifespan. Therefore, the cooling and lubrication mechanism is a core component ensuring the reliable operation of wet brakes. This mechanism, through the circulation of oil, lubricates and reduces friction on the friction pairs while removing heat. Its performance directly determines the braking stability, service life, and overall safety of the wet brake. Existing wet brake cooling and lubrication mechanisms generally suffer from low cooling and lubrication efficiency. The core issue lies in the unreasonable design of the oil flow path within the brake, leading to chaotic and disordered oil flow. During braking, the oil cannot accurately cover all friction pairs along the preset path, preventing the timely dissipation of large amounts of heat generated in localized areas. As heat continues to accumulate, the brake is prone to brake fade, manifested as a decrease in braking torque and sluggish braking response, severely impacting braking performance, especially under heavy-duty continuous operation scenarios. More importantly, the existing cooling and lubrication mechanisms lack effective oil temperature monitoring. When the oil temperature becomes too high due to continuous heat absorption, there is no timely feedback. Excessively high oil temperature will not only accelerate the oxidation and deterioration of the oil, reducing its lubrication performance and service life, but also aggravate the thermal deformation and wear of internal brake components, further shortening the overall service life of the brake.

[0003] Therefore, a wet brake cooling and lubrication mechanism is proposed to address the above problems. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a wet brake cooling and lubrication mechanism, which has the advantages of being able to rationally plan the oil flow path, accurately cover the friction pair area, prevent heat from not being carried away in time, reduce brake fade, and monitor and process the internal temperature to prevent excessive temperature from affecting the service life of the brake.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wet brake cooling and lubrication mechanism, comprising a brake body; The surface of the brake body is equipped with a cooling and lubrication assembly, which includes a conduction plate embedded inside the brake body, a circulation pipe surrounding and wrapped around the outer side of the conduction plate, a branch pipe for cooling and lubrication, an annular spray pipe, a nozzle head, and an oil storage mechanism. A temperature monitoring component is installed on the surface of the brake body. The temperature monitoring component includes a temperature monitoring module embedded in the inner wall of the conduction plate, a controller installed on the surface of the oil storage mechanism, and a valve body for controlling the spraying.

[0006] Preferably, two diverter pipes are symmetrically installed on the surface of the circulation pipe, the annular spray pipe is embedded inside the conductive plate, and the diverter pipe is connected to the annular spray pipe. A plurality of nozzles are evenly distributed on the surface of the annular spray pipe, and the oil storage mechanism is installed on the outer side of the brake body and is connected to the circulation pipe.

[0007] Preferably, the plurality of nozzles are arranged in a circumferential array around the center point of the annular spray pipe, and the spraying end of the nozzle is aligned with the inner sidewall of the conductive plate.

[0008] Preferably, a filter module and a cooling module are fixedly installed inside the oil storage mechanism, with the filter module located near the connection port between the oil storage mechanism and the circulation pipe, and the cooling module installed on the inner wall of the oil storage mechanism.

[0009] Preferably, an oil-resistant sealing gasket is installed at the connection between the circulation pipe and the diversion pipe.

[0011] Preferably, the valve body is mounted on the surface of the diverter pipe and is located inside the conductive plate, and the valve body is electrically connected to the controller.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model incorporates a cooling and lubrication assembly.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5 As shown, this utility model provides a wet brake cooling and lubrication mechanism, including a brake body 1; A cooling and lubrication assembly 2 is installed on the surface of the brake body 1. The cooling and lubrication assembly 2 includes a conduction plate 21 embedded inside the brake body 1, a circulation pipe 22 surrounding and wrapped around the outer side of the conduction plate 21, a diversion pipe 23 for cooling and lubrication, an annular spray pipe 24, a nozzle head 25, and an oil storage mechanism 26. Two shunt pipes 23 are symmetrically installed on the surface of the circulation pipe 22. The annular spray pipe 24 is embedded inside the conduction plate 21 and is connected to the shunt pipe 23. Multiple nozzles 25 are evenly distributed on the surface of the annular spray pipe 24. The oil storage mechanism 26 is installed on the outer side of the brake body 1 and is connected to the circulation pipe 22. The conduction plate 21 provides an efficient carrier for heat transfer. The combined structure of the circulation pipe 22, the shunt pipe 23, and the annular spray pipe 24 makes the oil flow path more regular and avoids the problem of chaotic flow. The overall structure allows the oil to act more accurately on the friction pair, effectively remove local heat, reduce brake fade, extend the service life of the brake, and improve braking safety.

[0018] Multiple nozzles 25 are arranged in a circular array around the center point of the annular spray pipe 24, and the spraying end of the nozzle 25 is aligned with the inner sidewall of the guide plate 21. The circular array arrangement makes the spraying range of the nozzles 25 form an annular coverage area, which can fully cover the friction pair area inside the brake.

[0019] The oil storage mechanism 26 has a filter module and a cooling module fixedly installed inside. The filter module is located near the connection port between the oil storage mechanism 26 and the circulation pipe 22, and the cooling module is installed on the inner wall of the oil storage mechanism 26. The filter module is located near the connection port, which can intercept impurities before the oil enters the circulation pipe 22, preventing impurities from clogging the circulation pipe 22, the nozzle head 25, or wearing friction pairs, thus ensuring smooth pipeline and component life. The cooling module is installed on the inner wall of the oil storage mechanism 26, which can quickly cool the high-temperature oil flowing back, so that the oil re-entering the circulation always maintains good heat absorption capacity, avoiding cooling failure caused by continuous rise in oil temperature, thus forming a closed loop of filtration-cooling-circulation.

[0020] An oil-resistant sealing gasket is installed at the connection between the circulation pipe 22 and the diversion pipe 23 to effectively prevent oil from seeping out from the connection gap and ensure a stable oil flow rate in the circulation pipe 22.

[0021] A temperature monitoring component 3 is installed on the surface of the brake body 1. The temperature monitoring component 3 includes a temperature monitoring module 31 embedded in the inner wall of the conduction plate 21, a controller 32 installed on the surface of the oil storage mechanism 26, and a valve body 33 for controlling the spraying. The controller 32 is electrically connected to the temperature monitoring module 31, and the controller 32 is electrically connected to the oil reservoir 26. The linkage between the temperature monitoring module 31 and the controller 32 enables real-time monitoring and intelligent control of oil temperature and brake temperature, which can provide timely warning of high temperature risks and ensure precise matching between cooling and lubrication actions and brake temperature status.

[0022] The valve body 33 is installed on the surface of the diversion pipe 23 and is located inside the transmission plate 21. The valve body 33 is electrically connected to the controller 32 and changes the oil flow rate in the diversion pipe 23 by adjusting its own opening degree.

[0023] Among them, the structures such as temperature monitoring module 31, controller 32, and valve body 33 are existing technologies, and their working principles are well-known technologies. The appropriate model is selected according to the actual use.

[0024] Working principle and process: After the brake body 1 begins braking, the heat generated by the intense friction of the friction pair is rapidly conducted to the conductive plate 21 embedded inside. At this time, the temperature monitoring module 31 embedded in the inner wall of the conductive plate 21 is immediately activated, collecting the temperature data of the conductive plate 21 in real time, and converting the temperature signal into an electrical signal for continuous transmission to the controller 32 on the surface of the oil reservoir 26. The controller 32 has built-in temperature threshold parameters and dynamically analyzes the received real-time temperature data to determine whether the current thermal state of the brake is within the safe operating range (normal operating temperature, warning temperature, danger temperature), providing a basis for subsequent oil control. Based on temperature monitoring results, the controller 32 activates the oil supply system of the oil storage mechanism 26. The oil first flows through the filter module at the connection port between the oil storage mechanism 26 and the circulation pipe 22 to remove residual minute impurities and prevent clogging of the nozzle head 25 or wear of the pipeline. If the real-time temperature approaches the warning threshold, the controller 32 simultaneously activates the cooling module on the inner wall of the oil storage mechanism 26 to pre-cool the oil, ensuring that the oil has good heat absorption capacity when it enters the circulation pipe 22. The treated oil flows along the circulation pipe 22. Because the circulation pipe 22 surrounds the outer side of the conduction plate 21, the oil initially absorbs some of the heat transferred by the conduction plate 21 during its flow. The oil carrying initial heat is diverted through the circulation pipe 22 to two symmetrically installed diversion pipes 23. The controller 32 sends a flow control signal to the valve body 33 installed on the surface of the diversion pipe 23 based on real-time temperature data. The higher the temperature, the larger the opening of the valve body 33, and the greater the oil flow. After being regulated by the valve body 33, the oil enters the annular spray pipe 24 embedded inside the conduction plate 21 and is sprayed out through the nozzles 25 evenly distributed on its surface. Since the spraying end of the nozzle 25 is aligned with the inner wall of the conduction plate 21, the oil can accurately cover all friction pair areas of the brake, achieving lubrication and friction reduction, reducing frictional heat generation; on the other hand, it directly absorbs the heat from the friction pair and the conduction plate 21, completing the dual function of lubrication and heat absorption. If the temperature monitoring module 31 detects that the temperature of the conduction plate 21 exceeds the preset warning threshold, it immediately sends an abnormal signal to the controller 32. The controller 32 then quickly executes three emergency measures: first, it increases the oil supply power of the oil storage mechanism 26 to improve the oil circulation speed; second, it controls the maximum opening of the valve body 33 to ensure maximum oil flow; and third, it starts the cooling module of the oil storage mechanism 26 to operate at full load, enhancing the cooling effect on the returning oil. Simultaneously, the controller 32 triggers a warning mechanism, sending a high-temperature warning to the operator and the entire system via audible and visual signals or data transmission, reminding them to pay attention to the braking status. If the temperature continues to rise to the dangerous threshold, the controller 32 can coordinate with the entire system to reduce the braking load and prevent brake fade. The lubricating oil, having absorbed heat, rises in temperature and flows back to the oil storage mechanism 26 along the inner wall of the conduction plate 21. After being cooled by the cooling module and filtered a second time by the filtration module, it re-enters the pipeline, forming a closed-loop cycle of filtration-cooling-transportation-heat absorption-return. When the brake body 1 stops braking, the heat generated by the friction pair decreases, and the temperature of the conduction plate 21 gradually decreases. When the temperature monitoring module 31 detects that the temperature has dropped to the safe lower limit, the controller 32 sequentially shuts down the cooling module of the oil storage mechanism 26 and reduces the oil supply flow. After the oil completes its final circulation return, the control valve 33 closes, and all components return to their initial standby state, awaiting the next start command.

[0025] Throughout the process, the design of the circulation pipe 22 surrounding the conduction plate 21, together with the precise spraying of the spray pipe, forms a dual heat control of active heat absorption and direct cooling. With the intervention of temperature monitoring throughout the process, efficient protection of the brake is achieved.
