The driving shaft mud test bed provided by the embodiment comprises a driving motor 1, a driven assembly 1a, an induced draft assembly 2, a temperature sensor 3, a spraying assembly 4, a driving clamp 5, an intermediate shaft clamp 6, a transmission shaft clamp 7, a vertical guide rail seat 8, a horizontal guide rail seat 9, a hot air blower 10, an environment box 11, a hot air inlet 11a and a bottom plate 12. The specific structure, connection relationship and operation principle of the aforementioned components will be described below with reference to fig. 1.
As shown in fig. 1, in the example given in fig. 1, the drive shaft may comprise a propeller shaft and an intermediate shaft, a first end of the propeller shaft and a first end of the intermediate shaft being connected with a universal joint for connection with the active clamp 5, a second end of the propeller shaft being connected with a propeller shaft clamp 7 via a universal joint, and a second end of the intermediate shaft being connected with an intermediate shaft clamp 6. The clamp can be compatible with drive shafts of different sizes so as to achieve high compatibility. In the embodiment, the aforementioned active clamp 5, the transmission shaft clamp 7 and the intermediate shaft clamp 6 are all disposed in a closed environment box 11, so that in the embodiment, the actual working state of the driving shaft is further simulated in the environment box 11.
Still referring to fig. 1, the environmental chamber 11 can simulate the actual environment of the entire vehicle in which the driving shaft is located through the induced air assembly 2, the temperature sensor 3, the injection assembly 4, the hot air blower 10 and the hot air inlet 11 a. Wherein the jetting assembly 4 may comprise a main pipe arranged inside the environmental chamber 11, the main pipe may be located above the driving shaft and arranged in a horizontal direction. The main pipe may further be provided with a plurality of nozzles, for example, 5 nozzles, arranged in the horizontal direction, and the nozzles of the nozzles may face the drive shaft, so that fluid can be ejected to a plurality of positions of the drive shaft. In the operating state of the jet assembly 4, the main pipe of the jet assembly 4 may be in fluid communication with a test fluid, which may be a mixture of water and certain impurities, corresponding to the environment to which the drive shaft is intended to be subjected when it is mounted on the vehicle, for example, the test fluid may be slurry.
Further, in the embodiment, the environment box 11 and the air heater 10 may be disposed side by side on the bottom plate 12, and the air heater 10 is used for outputting hot air, and it may be connected to the hot air inlet 11a pre-opened on the environment box 11 through a pipeline. In this way, when the hot air is output from the hot air blower 10, the hot air flows into the environment tank 11 through the hot air duct and the hot air inlet 11a, thereby increasing the temperature in the environment tank 11.
Further, another advantage of increasing the temperature inside the environment tank 11 using the hot air blower 10, the hot air duct, and the hot air inlet 11a is that the driving shaft can be directly blown with the hot air flowing into the environment tank 11 through the hot air inlet 11 a. Although the hot air inlet 11a is shown in fig. 1 not to face the drive shaft, the hot air inlet 11a may be disposed to face a certain portion of the drive shaft to achieve the aforementioned blow-through operation. In an example not shown, there may be a plurality of hot air inlets 11a, and the plurality of hot air inlets 11a may be distributed at different positions on the environmental chamber 11 to meet the demand for the direct blowing operation and the individual demand for the increased temperature. Further, in this not shown example, the hot air blower 10 and the pipes may correspond to the number of the hot air inlets 11a, or the hot air inlets 11a and the pipes may be one each, and different functions of the hot air may be achieved by installing the pipes between different hot air inlets 11 a.
In the embodiment, the use of the hot air blower 10, the hot air duct and the hot air inlet 11a to increase the temperature inside the environmental chamber 11 is particularly advantageous for simulating a high temperature environment, and may further simulate a working environment in which hot air is directly blown, which allows the working environment of the driving shaft to be effectively simulated. On the basis of this, the temperature in the environmental chamber 11 is monitored in real time by the temperature sensor 3 and a controller, not shown, and thus fed back to the power regulation of the air heater 10 to control the temperature in the environmental chamber 11.
On this basis, induced air subassembly 2 includes induced air passageway and sets up the exhaust fan in induced air passageway inside, and the exhaust fan also can be controlled by above-mentioned controller to it can initiatively open, takes out hot-air from the environmental chamber 11, with the temperature in reducing environmental chamber 11, further ensures that the temperature in the environmental chamber 11 is regulated and control effectively.
Therefore, in the embodiment, the hot air blower 10, the hot air pipe, the hot air inlet 11a and the induced air assembly 2 are combined with the injection assembly 4, so that the environments of the driving shaft, such as normal temperature, high temperature, dryness and wetness, in the running process of the whole vehicle can be simulated, and the reference of data obtained after the driving shaft is tested, particularly the sealing data of the bearing and the universal joint, is greatly improved.
On the basis, the installation angle of the driving shaft can be further adjusted to simulate the installation angle of a transmission shaft of the driving shaft when the driving shaft is installed on the whole vehicle. As shown in fig. 1, in which a driving shaft clamp may be fixed to a left side wall plate of an environment box 11, a driving shaft clamp 7 may be provided to a mounting base via a vertical rail base 8. In an embodiment the mounting may be provided with a vertical guide rail extending in a vertical direction, the vertical guide rail may extend in a vertical direction, the vertical rail seat 8 cooperates with the vertical guide rail such that the vertical rail seat 8 is slidable in the vertical direction.
Further, the environmental chamber 11 further comprises a horizontal wall plate to which the mounting seat is mounted via a horizontal rail seat 9. Horizontal guide rails can be arranged on the horizontal wall plates, so that the horizontal guide rail seats 9 can be matched with the horizontal guide rails, and the installation seat can move along the horizontal guide rails. Taking the vertical guide rail seat 8 as an example, a lead screw arranged side by side with the vertical guide rail can be arranged along the vertical direction, a nut can be further sleeved on the lead screw, the nut can be connected with the vertical guide rail seat 8, and the height of the vertical guide rail seat 8 can be adjusted by rotating the hand wheel through the hand wheel and some gear transmission assemblies positioned between the lead screw and the hand wheel. Likewise, the position of the horizontal rail base 9 can be adjusted in this way. Therefore, the length of different transmission shafts can be adapted and different installation angles can be provided for the transmission shafts by adjusting the positions of the mounting seats and the positions of the vertical guide rail seats 8.
Furthermore, the intermediate shaft clamp 6 can also be arranged on a horizontal guide rail, and the intermediate shaft can be horizontally installed, so that the intermediate shaft clamp 6 can be moved to adapt to intermediate shafts with different lengths.
In the embodiment, with the above-described features, the propeller shaft jig 7, the drive shaft jig, the vertical rail base 8, and the horizontal rail base 9 are disposed such that the installation angle of the propeller shaft is in the range of 0 to 25 degrees. The mounting angle referred to herein means an angle formed by the axis of the propeller shaft with respect to the horizontal direction. The drive shaft may be inclined in such a manner that its second end is inclined upwardly with respect to the first end, i.e. as shown in fig. 1; or may be inclined downwardly relative to the first end, in which case it is not shown.
By utilizing the installation angle, the actual installation angle of the transmission shaft in the whole vehicle is effectively simulated, and the test is carried out under the installation angle, so that the working state of the transmission shaft can be restored, and the reference value of the obtained test data is further increased.
In the embodiment, the active gripper 5 is driven by the drive motor 1. As shown in fig. 1, the driving motor 1 may be mounted on the base plate 12, and the driving motor 1 may be a variable frequency motor. Further, the driving motor 1 may realize power transmission with the driving jig 5 via a driven assembly 1a, and the driven assembly 1a may be formed as, for example, a timing belt and a timing wheel. Since the inverter motor is used, the rotational speed of the drive shaft can be effectively adjusted, and it is preferable that the inverter motor be used to enable stable operation of the drive shaft at any speed within a range of 100 to 3000rmp, for example, 200rmp, 500rmp, 900rmp, 1400rmp, 1900rmp, 2500rmp, or 2800 rmp. Therefore, different gear speeds of the driving shaft during the operation of the whole vehicle can be simulated, so that the test environment of the driving shaft is closer to the real working environment of the driving shaft.
However, without being limited thereto, although the test case of only one drive shaft is shown in the above example, in the present embodiment, a larger size of the environmental chamber 11 may be employed to provide more drive shafts as above.
The driving shaft slurry test bed provided by the embodiment has the advantages of simple structure and low manufacturing cost; different gear speeds of the whole vehicle corresponding to the driving shaft can be simulated by controlling the variable-frequency driving motor 1; by controlling the air heater 10, the induced draft assembly 2 and the injection assembly 4, the environment of the driving shaft at normal temperature, high temperature, dryness and wetness and the like in the running process of the whole vehicle can be simulated; by adjusting the positions of the vertical rail seat 8 and the horizontal rail seat 9, the actual installation angle of the drive shaft in the whole vehicle can be simulated. Thus, the drive shaft mud test bed provided by the embodiment provides data support for detecting the sealing performance of the bearing and the universal joint, and provides an important reference for improving the design of the sealing element.
The present embodiment also provides a method for testing mud in a drive shaft, which includes:
arranging a driving shaft in the closed space and adjusting the temperature of the closed space;
in particular, the temperature of the enclosed space is regulated by means of a hot gas flow delivered into the enclosed space, more particularly at least part of the hot gas flow is blown straight through the drive shaft;
