Description

Technical Field

[0001] This disclosure relates to the technical field of oil seal simulation, and more specifically to an oil injection simulation method, apparatus, storage medium, and electronic equipment for bidirectional oil seals. Background Technology

[0002] In the drive axle sealing system, oil seals are important sealing components, so verifying their wear resistance and cold resistance becomes particularly important. The oil seal unit test generally involves clamping a single oil seal on a rotary shaft test bench, injecting test lubricating oil, and controlling the lubricating oil level. Essentially, the oil seal is immersed in the test lubricating oil, or the oil seal is allowed to come into contact with a portion of the oil carried by the rotary shaft.

[0003] Current testing methods only apply to single oil seals, meaning the oil seal can only be placed on a rotating shaft and injected with one type of test lubricant. This method is limited to testing individual oil seals with only one lubrication method and cannot be applied to bidirectional oil seals, which involve placing the oil seal on a rotating shaft and injecting two different test lubricants on both sides, using different lubrication methods on each side of the bidirectional oil seal. For example, one side of the bidirectional oil seal is lubricated by splash lubrication while the other side is lubricated by active lubrication.

[0004] Current oil seal tests tend to immerse the entire oil seal in test lubricating oil, or allow the oil seal to come into contact with a portion of the oil carried by the rotating shaft. This approach fails to accurately simulate the actual oil level at the contact surface between the oil seal and the rotating shaft under various lubrication methods, such as active lubrication and splash lubrication in the drive axle. This can easily lead to situations where, even if the oil seal's performance and structure meet the requirements, excessive lubricating oil can completely submerge the seal, or the oil level carried by the rotating shaft can be too high, failing to reflect the actual oil level at the seal-shaft-hole mating position under different vehicle operating conditions. This results in oil leakage during individual oil seal tests.

[0005] Existing oil seal unit tests typically involve clamping a single oil seal onto a rotary shaft test bench, injecting test lubricating oil, and controlling the oil level. Essentially, this means immersing the oil seal in the test lubricating oil or allowing it to come into contact with a portion of the oil carried up by the rotary shaft. This approach fails to accurately simulate the actual oil condition at the contact surface between the oil seal and the rotary shaft under various lubrication methods, such as active lubrication and splash lubrication in drive axles. This can easily lead to leaks in the oil seal unit test even when the seal's performance and structure meet the requirements, due to excessive lubricating oil (either completely submerging the seal or causing excessive oil carryover during shaft rotation). This discrepancy with the actual oil level at the seal-shaft / hole mating position under different vehicle operating conditions can result in leaks. Summary of the Invention

[0006] The purpose of this disclosure is to provide a method, apparatus, storage medium, and electronic device for simulating oil injection for bidirectional oil seals, in order to solve the problems existing in the prior art.

[0007] To solve the above-mentioned technical problems, the embodiments of this disclosure adopt the following technical solutions:

Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely to serve as the basis and representative basis for the claims to teach those skilled in the art to use this disclosure in a variety of substantially any suitable detailed structures.

[0037] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in still another embodiment,” all of which may refer to one or more of the same or different embodiments according to this disclosure.

[0038] The first embodiment of this disclosure provides a method for simulating oil injection in a bidirectional oil seal, which is used to simulate the oil injection effect in a single test of the bidirectional oil seal. The method for simulating the oil injection effect mainly refers to simulating the actual liquid level height of the oil seal in the drive axle under different operating conditions by establishing an oil injection system model before the oil seal test. This further determines the injection parameters, such as the oil pipe's requirement to inject lubricating oil into the oil seal during the single test, so as to facilitate the final measurement and evaluation of the actual test results of the oil seal.

[0039] S101, A fuel injection system model is established based on a drive axle with an oil seal to be tested.

[0040] In this step, a fuel injection system model is established based on the drive axle with the oil seal to be tested. Specifically, in order to simulate fuel injection lubrication in a bidirectional oil seal unit test, an accurate and detailed drive axle simulation model needs to be established first. This drive axle simulation model includes the oil seal to be tested. The drive axle simulation model is achieved by assembling multiple sub-models. These sub-models can be, for example, sub-models of predetermined components in the drive axle, such as the drive axle housing, shaft gears, driving and driven bevel gears, differential, oil seal, and other important components. The sub-models can also be environmental subsystem models, fuel quantity monitoring subsystem models, fuel quantity calculation subsystem models, fuel injection control subsystem models, etc., for different operating conditions.

[0041] Once the component sub-models and system sub-models involved in the drive axle modeling are all constructed, the constructed sub-models are assembled according to the internal assembly requirements of the drive axle. Here, sub-models that have no significant impact on the lubrication effect of the drive axle or the oil level at the position of the oil seal mating shaft and hole can be simplified in assembly, ultimately resulting in the oil injection system model.

[0042] S102, input the lubricating oil quantity and the operating parameters of the predetermined operating condition into the oil injection system model to obtain the lubricating oil level height in contact with the oil seal to be tested under the predetermined operating condition.

[0043] After establishing the oil injection system model based on the drive axle with the oil seal to be tested through the above step S101, in this step, the lubricating oil quantity and the operating parameters of the predetermined operating condition are input into the oil injection system model to obtain the height of the lubricating oil level contacted by the oil seal to be tested under the predetermined operating condition.

[0044] Specifically, the amount of lubricating oil to be added to the drive axle is input into the established oil injection system model. The amount of lubricating oil is based on meeting the lubrication requirements of important components inside the drive axle. These components may include, for example, various bearings, drive bevel gears, driven bevel gears, etc.

[0045] Furthermore, various commonly used speeds and times in actual vehicle conditions are selected as operating parameters to simulate different operating conditions. These simulated pre-defined operating conditions include the vehicle's maximum speed, high-speed operation, low torque operation, maximum power operation, maximum torque operation, maximum reverse torque operation, and reversing operation. These pre-defined operating conditions are determined based on the output speed and duration of the drive axle.

[0046] The specific operating conditions selected are shown in Table 1 below. The corresponding output speed and duration will be determined based on the actual situation.

[0047] Table 1 Comparison of Vehicle's Predetermined Operating Conditions with Drive Axle Output Speed ​​and Speed ​​Duration

[0048] Serial Number Drive axle output speed (rpm) Time (h) Remark 1 1487 (For reference only) 3 (For reference only) Simulated vehicle top speed conditions 2 1202 (For reference only) 4 (For reference only) Simulated vehicle high-speed conditions 3 505 (For reference only) 162 (For reference only) Simulate common operating conditions of vehicles with low torque 4 207 (For reference only) 10 (For reference only) Simulated vehicle maximum power condition 5 175 (for reference only) 10 (For reference only) Simulated vehicle maximum torque condition 6 -215 (For reference only) 2 (For reference only) Simulating the maximum torque condition of a vehicle in reverse gear 7 -175 (For reference only) 7 (For reference only) Simulated vehicle reversing conditions

[0049] The determined operating parameters of the predetermined operating conditions are used as input parameters and input into the oil injection system model. The oil injection system model will then begin simulation calculations of oil injection at different output speeds. Specifically, the oil quantity monitoring subsystem in the oil injection system model monitors the calculation results in real time, and after the simulation is completed, obtains the level of lubricating oil in contact with the oil seal under different predetermined operating conditions.

[0050] S103, input the lubricating oil level height into the oil injection system model to obtain the injection parameters for injecting lubricating oil onto the oil seal to be tested.

[0051] After inputting the lubricating oil quantity and the operating condition parameters of the predetermined operating condition into the oil injection system model through the above step S102 to obtain the lubricating oil level height in contact with the oil seal to be tested under the predetermined operating condition, in this step, the lubricating oil level height is input into the oil injection system model to obtain the oil injection parameters for injecting lubricating oil onto the oil seal to be tested.

[0052] Specifically, the obtained lubricating oil level is input into the oil volume calculation system sub-model of the oil injection system model to calculate the oil injection parameters that the oil pipe in the drive axle needs to inject lubricating oil into the oil seal to be tested in the single test of the bidirectional oil seal. The oil injection parameters here may be, for example, the oil injection quantity, the injection speed, and the injection position.

[0053] In some embodiments, based on the acquired injection parameters, an actual lubrication test of the bidirectional oil seal can be initiated. Therefore, after step S103 above, the following method is further included:

[0054] The injection of lubricating oil is controlled based on the injection parameters to obtain the injection results.

[0055] After obtaining the injection parameters for the lubricating oil to be sprayed onto the oil seal under test through step S103, this step controls the injection of lubricating oil based on the injection parameters to obtain injection results for comparison. Specifically, after obtaining the injection parameters through simulation, the actual injection is controlled based on the injection parameters to obtain actual injection results. Specifically, the oil seal under test is clamped on the test device, the oil pipe in the drive axle is connected to the oil injection control subsystem of the oil injection system model, and the injection parameters calculated by simulation are input into the oil injection control subsystem. The lubricating oil will pass through the oil pipe and be sprayed to different positions of the oil seal under test in the actual working condition, and finally the actual test of the bidirectional oil seal ends.

[0056] Furthermore, after the above-mentioned actual test is completed, the sealing ability of the oil seal under test is evaluated by measuring the state changes of the oil seal before and after the actual test. For example, the lip size, outer diameter and secondary lip size of the bidirectional oil seal in the spring-loaded and springless states are obtained, as well as the assembly force, disassembly force and radial force of the bidirectional oil seal. This allows for the evaluation of the sealing ability of the oil seal under test and the acquisition of accurate test results.

[0057] This embodiment of the invention addresses the issue of bidirectional oil seals. Before the oil seal test, an oil injection system model is used to simulate the actual liquid level of the oil seal under different predetermined working conditions. The oil injection parameters that the oil pipe needs to spray lubricating oil onto the oil seal under test during the individual test are calculated. This precise simulation calculation can reasonably avoid the problems caused by the overall immersion test method during the individual oil seal test, greatly speeding up the individual oil seal test. Furthermore, by simulating the actual working conditions, the oil seal test is made closer to the actual use conditions, ensuring the accuracy and reliability of the test results.

[0067] Furthermore, the predetermined operating condition is determined based on the output speed and duration of the drive axle.

[0068] Furthermore, in the step of inputting the lubricating oil level height into the oil injection system model to obtain the injection parameters for injecting lubricating oil onto the oil seal to be tested, the injection parameters include at least the injection quantity, injection speed, and injection position.
