Description

Technical Field

[0002] The main reducer assembly is an important part of the power transmission system of a passenger car. In addition to transmitting torque, the main reducer assembly also has the functions of reducing speed, increasing torque, and changing the direction of power.

[0003] The main reducer assembly is mainly composed of reducer housing, spiral bevel gears, bearings, differentials, flanges, etc., among which the spiral bevel gears are the core components, and their performance directly affects the NVH (Noise, Vibration, Harshness) and fatigue strength of the reducer assembly. There are many factors that affect the performance of spiral bevel gears, including contact area morphology, gear tooth accuracy, transmission error, etc., among which the contact area morphology is one of the most important factors affecting the performance of spiral bevel gears.

[0004] From the perspective of assembly structure, the main reducer assembly can be divided into side cover type and rear cover type. For the main reducer assembly with rear cover structure, since the driven bevel gear is placed outside the reducer housing, the contact area can be inspected and evaluated intuitively. For the main reducer assembly with side cover structure, since the driven bevel gear is inside the reducer housing, the side cover of the main reducer assembly needs to be frequently installed and disassembled during the contact area inspection. This process requires repeated tightening and loosening of screws, which leads to low inspection efficiency. Summary of the invention

[0038] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0039] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0040] It should be noted that during the production and adjustment of the vehicle's main reducer assembly, it is necessary to perform morphological detection on the tooth surface contact area of ​​the relevant gears in the main reducer assembly. For the main reducer assembly with a side cover structure, the prior art has a very cumbersome process for detecting and evaluating the tooth surface contact area, which mainly includes the following steps: 1. Apply yellow lead powder to the driven bevel gear and place it inside the main reducer assembly together with the differential assembly; 2. Place the side cover; 3. Tighten the side cover positioning bolts according to the specified torque; 4. Rotate the flange inside the reducer several times; 5. Loosen the side cover bolts; 6. Remove the side cover, take out the driven bevel gear and the differential assembly, and observe the morphology of the tooth surface contact area.

[0041] It can be seen that each time the tooth surface contact area of ​​the main reducer assembly is subjected to morphological inspection, the side cover needs to be assembled and disassembled by tightening and loosening the bolts. This process is cumbersome, time-consuming and labor-intensive, which not only affects the assembly rhythm of the reducer assembly, but also the repeated assembly and disassembly of the side cover bolts can easily damage the threaded holes on the reducer housing.

[0042] In view of the problems existing in the above-mentioned prior art, an embodiment of the present application provides a contact area detection system for a main reducer assembly, which can realize rapid and efficient detection of the tooth surface contact area of ​​the main reducer assembly.

[0043] See also Figures 1 to 3 , the embodiment of the present application provides a contact area detection system for a main reducer assembly, including a positioning base 1, a clamping device 2, a controller and a driving device 3;

[0044] The positioning base 1 is provided with a positioning mechanism 101 adapted to the reducer assembly to be tested;

[0045] The pressing device 2 includes a pressing top plate and a telescopic rod, and the pressing top plate is connected to the positioning base 1 through the telescopic rod;

[0046] The controller is used to control the telescopic rod to drive the pressing top plate to move along the output shaft direction of the reducer assembly to be tested, so as to press or loosen the side cover of the reducer assembly to be tested;

[0047] The controller is also used to control the driving device 3 to provide a test driving force to the reducer assembly to be tested.

[0048] It should be noted that the contact area detection system of the main reducer assembly can be set up in a special workstation newly added to the original production line. By developing special non-standard equipment and corresponding tooling, fast and efficient detection of the tooth surface contact area of ​​the main reducer assembly can be achieved.

[0049] Specifically, the contact area detection system of the main reducer assembly mainly includes a positioning base 1, a clamping device 2, a controller and a driving device 3. Among them, the positioning base 1 is used to place the reducer assembly to be tested, and a positioning mechanism 101 is provided on the positioning base 1, which is used to limit the reducer assembly to be tested to remain relatively fixed with the positioning base 1. Exemplarily, the positioning mechanism 101 can be a buckle that matches the outer shell structure of the reducer assembly to be tested; or, the positioning mechanism 101 can be a fixing member with a columnar protrusion, which is perpendicular to the plane where the side cover is located, and the positioning hole on the outer shell of the reducer assembly to be tested can be inserted into the columnar protrusion of the fixing member, thereby limiting the reducer assembly to be tested as a whole to be fixed on a plane perpendicular to the columnar protrusion.

[0050] The clamping device 2 includes a clamping top plate and a telescopic rod, one end of the telescopic rod is fixedly connected to the positioning base 1, and the other end is fixedly connected to the clamping top plate, and the telescopic rod is telescopic along the output shaft direction of the reducer assembly to be tested. Based on this, the controller can control the telescopic rod to drive the clamping top plate to move left and right along the output shaft direction of the reducer assembly to be tested, so as to achieve the clamping or loosening of the side cover of the reducer assembly to be tested. Among them, the telescopic rod can be controlled by hydraulic transmission.

[0051] It can be understood that after the reducer assembly to be tested is placed on the positioning base 1 and fixed by the positioning mechanism 101, the side cover is then placed at a suitable position of the reducer assembly to be tested, and the clamping device 2 is controlled to clamp the side cover, thereby completing the test assembly of the reducer assembly to be tested. There is no need to tighten the positioning bolts on the side cover, and the operating condition test of the reducer assembly to be tested can be started.

[0052] After clamping the side cover of the reducer assembly to be tested, the drive device 3 is controlled to provide a test driving force to the reducer assembly to be tested, for example, by driving the flange (flange) of the reducer assembly to be tested to rotate, so that the master and slave bevel gears inside the reducer assembly to be tested are meshed and transmitted. After rotating a preset number of circles or a preset time, the drive device 3 is turned off, and then the clamping device 2 is released. At this time, the side cover can be removed to obtain the contact area morphology of the gear tooth surface inside the reducer assembly to be tested. It can be understood that the drive device 3 can use a small drive motor that can be used to provide speed and torque control. The drive device 3 is equipped with a drive shaft adapted to the reducer assembly to be tested, and the drive shaft can be used to achieve the drive device 3 and the main tooth flange of the reducer assembly to be tested. Quick engagement or disengagement.

[0053] Based on this, the clamping force can be applied to the side cover through the clamping device 2, instead of fixing the side cover by tightening the bolts, thereby greatly reducing the process and time of contact area detection on the reducer assembly to be tested, improving the efficiency of contact area detection, and because the process of repeatedly tightening and loosening the bolts is eliminated, the damage to the threaded holes on the reducer housing during the detection process is effectively avoided, thereby improving the reliability of the product.

[0054] In some possible embodiments, the driving device 3 includes an input-end driving device 301 and an output-end driving device 302;

[0055] The controller is used to control at least one of the input end driving device 301 and the output end driving device 302 to provide a test driving force to the reducer assembly to be tested.

[0056] Specifically, the drive device 3 may include an input end drive device 301 and an output end drive device 302, wherein the input end drive device 301 is used to provide a rotational speed or torque (set according to the detection requirements) to the input end of the reducer assembly to be tested, and the output end drive device 302 is used to provide a rotational speed or torque (set according to the detection requirements) to the output end of the reducer assembly to be tested. It can be understood that the input end drive device 301 is connected to the power input end of the reducer assembly to be tested through the input drive shaft, and the output end drive device 302 is connected to the power output end of the reducer assembly to be tested through the output drive shaft.

[0057] It should be noted that, during the test process, only the input end drive device 301 can be controlled to provide a test driving force from the input end of the reducer assembly to be tested to it, at this time, the working condition in which the engine drives the reducer to idle while the load end is unloaded is simulated; only the output end drive device 302 can be controlled to provide a test driving force from the output end of the reducer assembly to be tested to it, at this time, the working condition in which the reducer is driven to rotate from the load end of the reducer while there is no engine connected to the input end is simulated; the input end drive device 301 and the output end drive device 302 can also be controlled to provide a test driving force to the reducer assembly to be tested at the same time, wherein the input end drive device 301 is equivalent to providing a driving torque to the input end of the reducer assembly to be tested, and the output end drive device 302 is equivalent to providing a resistance torque to the load end of the reducer assembly to be tested, at this time, the working condition in which a normal engine drives the reducer to rotate and the output end of the reducer is subjected to the resistance of the wheel end is simulated.

[0058] Based on this, test driving force is provided to the reducer assembly to be tested in a variety of ways, so as to simulate the actual operating conditions of complex scenarios and ensure the comprehensiveness and effectiveness of the contact area detection of the reducer assembly.

[0059] In some possible embodiments, an auxiliary support member 102 is further provided on the positioning base 1 , and the auxiliary support member 102 is used to provide support force for the input end housing of the reducer assembly to be tested.

[0060] It should be noted that, since the main reducer assembly as a whole has the characteristics of a smaller volume at the input end and a larger volume at the output end, in order to ensure that the plane formed by the input shaft and the output shaft of the reducer assembly to be tested is parallel to the plane where the positioning base 1 is located, an auxiliary support member 102 can be provided on the positioning base 1 to support the input end housing of the reducer assembly to be tested at a certain height.

[0061] In addition, in order to adapt to the main reducer assembly structure of different specifications and models, the auxiliary support member 102 can also be set to be height-adjustable. The auxiliary support member 102 can be controlled to rise or fall through the controller to support the input end housing of the reducer assembly to be tested to reach a suitable height, so that the input shaft and output shaft of the reducer assembly to be tested are parallel to the plane where the positioning base 1 is located.

[0062] In the embodiment of the present application, an auxiliary support member 102 is provided to support the input end housing of the reducer assembly to be tested, thereby further improving the stability and reliability of the reducer assembly to be tested during the test process.

[0063] In some possible embodiments, there are at least two clamping devices 2, and the at least two clamping devices 2 are respectively controlled by a controller to clamp or loosen the side cover of the reducer assembly to be tested.

[0064] It should be noted that at least two pressing devices 2 may be provided so as to press the side cover of the reducer assembly to be tested from different positions.

[0065] Exemplarily, two clamping devices 2 can be respectively arranged at two ends symmetrically about the reducer output axis, so as to provide uniform clamping force to the side cover of the reducer assembly to be tested, further improving the stability and reliability of the reducer assembly to be tested during the test process.

[0066] In some possible embodiments, there are at least two positioning mechanisms 101 , and the at least two positioning mechanisms 101 are matched with at least two positioning holes of the reducer assembly to be tested.

[0067] It should be noted that, in order to further improve the relative fixity between the reducer assembly to be tested and the positioning base 1, a positioning mechanism 101 may be provided on the positioning base 1 according to the multiple positioning holes of the housing of the reducer assembly to be tested.

[0068] It can be understood that when the reducer assembly to be tested is positioned by only one positioning mechanism 101 and one positioning hole, or the central axes of multiple positioning holes of the reducer assembly to be tested are located on the same straight line, and assuming that there are no other positioning restrictions, the reducer assembly to be tested can still rotate based on the positioning hole as the central axis; then, when the reducer assembly to be tested is positioned by at least two positioning mechanisms 101 and corresponding positioning holes, and the central axes of at least two positioning holes are not located on the same straight line, even in the absence of other positioning restrictions, the reducer assembly to be tested can be restricted to remain relatively fixed with the positioning base 1. Therefore, by providing multiple positioning mechanisms 101 that are compatible with the positioning holes of the reducer assembly to be tested, the stability and reliability of the reducer assembly to be tested during the test process can be further improved.

[0069] In some possible embodiments, the clamping top plate can rotate circumferentially based on the telescopic rod as an axis, and the controller is further used to control the clamping top plate to rotate to a required position based on the telescopic rod as an axis according to the test instruction.

[0070] It should be noted that when the positioning mechanism 101 realizes the positioning and fixing of the reducer assembly to be tested by nesting the columnar protrusion in the same direction as the reducer output shaft with the positioning hole of the reducer housing, since the positioning hole of the reducer assembly housing to be tested is nested into the columnar protrusion of the positioning mechanism 101, there is a process of moving the reducer assembly to be tested left and right along the output shaft direction as a whole. Therefore, even when the clamping device 2 is loosened, it may still be hindered by the clamping device 2 pressing the top plate.

[0071] To this end, the clamping top plate can be set to rotate circumferentially with the telescopic rod as the axis, and the controller can control the clamping top plate to rotate to the required position according to the test requirements. Specifically, when the side cover needs to be clamped, the clamping top plate is controlled to rotate to a position where a clamping force can be applied to the side cover along the output shaft direction (such as Figure 1 When the side cover needs to be loosened and removed, the clamping top plate is controlled to rotate to a position that can avoid restricting the movement of the reducer assembly to be tested in the output shaft direction (as shown in the figure); Figure 2 and Figure 3 shown).

[0072] Based on this, by controlling the clamping top plate to rotate to the required position according to the test state, the efficiency of placing or replacing the reducer assembly to be tested can be improved, and the convenience of contact area detection of the reducer assembly to be tested can be effectively improved.

[0073] See also Figure 4 The embodiment of the present application provides a contact area detection method of a main reducer assembly, which is applied to any contact area detection system of a main reducer assembly, including:

[0074] S1. After determining that the reducer assembly to be tested is matched and fixed with the positioning mechanism 101, control the pressing device 2 to press the side cover of the reducer assembly to be tested;

[0075] S2, controlling the driving device 3 to move and connect to the output end or input end of the reducer assembly to be tested, and providing a test driving force to the reducer assembly to be tested based on a preset test instruction;

[0076] S3. After a preset driving cycle, the driving device 3 is turned off, and the clamping device 2 is controlled to loosen the side cover of the reducer assembly to be tested.

[0077] Specifically, it can be determined whether the reducer assembly to be tested and the positioning mechanism are matched and fixed based on sensors or visual recognition and other technologies. After it is determined that the reducer assembly to be tested and the positioning mechanism are matched and fixed, the clamping device is controlled to clamp the side cover of the reducer assembly to be tested. At this time, there is no need to tighten the bolts of the side cover, and the working condition simulation test of the reducer assembly to be tested can be carried out.

[0078] Subsequently, the driving device is controlled to move and connect to the output end or the input end of the reducer assembly to be tested, and provides a test driving force to the reducer assembly to be tested based on a preset test instruction;

[0079] Finally, after providing the test driving force and after a preset driving cycle, the driving device is turned off, where the preset driving cycle can be a preset number of rotations or a rotation time; after turning off the driving device, the clamping device is loosened so that the contact area morphology can be obtained after removing the side cover, thus completing a contact area detection process. In this process, there is no need to tighten or loosen the positioning bolts on the side cover, thereby effectively improving the efficiency of contact area detection of the reducer assembly to be tested.

[0080] In some embodiments, the clamping top plate can also be arranged to rotate circumferentially with the telescopic rod as the axis. After the clamping device is loosened, the clamping top plate is controlled to automatically rotate to a position that can avoid restricting the movement of the reducer assembly to be tested in the direction of the output shaft. When the side cover needs to be clamped, the clamping top plate is controlled to rotate to a position where a clamping force can be applied to the side cover along the output shaft direction, and then the telescopic rod is controlled to contract to clamp the side cover.

[0081] In some embodiments, when it is determined that the reducer assembly to be tested is not in a horizontal state, the auxiliary support member can be controlled to be raised and lowered to a suitable position until the reducer assembly to be tested is in a horizontal state (i.e., the reducer input shaft and output shaft are both parallel to the plane where the positioning base is located).
