Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile technology, in particular to a control method and device for a driving shaft assembly circumferential gap. BACKGROUND

[0002] The automobile driving shaft assembly is a component that transmits engine torque to the wheels. The engine torque is transmitted to the wheels through the transmission, differential, driving shaft assembly and brake assembly to drive the wheels to run.

[0003] As a transmission system, each part has a gap inside. When the vehicle is refueling or braking, the sudden change in torque causes all the gap values of each part of the transmission system to cause a slight metallic impact noise at the front end of the vehicle. In order to reduce the impact of the entire vehicle transmission system, improve the driving experience of the user, and reduce the driving shaft assembly circumferential gap value, it becomes a technical problem that needs to be solved.

[0004] However, the three-pin joint assembly gap value generated after the axle fork ball channel and the ball ring are assembled is the most critical control factor among several factors that affect the driving shaft assembly circumferential gap value. The three-pin joint assembly gap value must be controlled within a reasonable range. A large gap value will cause the driving shaft assembly to be loose.

[0005] After the ball ring is installed inside the axle fork ball channel, in order to ensure that it does not jam and interfere during operation, the relationship between the two is designed as a gap fit. Because the ball ring has a range of diameters, and the axle fork ball channel also has a range of diameters, if the precision forged axle fork and ball ring are randomly paired and assembled, there may be a large gap value. For example, the axle fork with the upper limit of the design value of the ball channel diameter is assembled with the ball ring with the lower limit of the design value of the diameter. The three-pin joint assembly gap value after assembly will be larger, which will exceed the desired assembly gap value, and produce unqualified three-pin joint assemblies. SUMMARY

[0006] The present application provides a control method and device for a driving shaft assembly circumferential gap, which is used to solve the technical problem of large three-pin joint assembly gap value produced, resulting in low three-pin joint assembly yield. The technical solution of the present application is as follows:

[0007] According to the first aspect of the present application, a control method for a driving shaft assembly circumferential gap is provided, comprising: arranging a plurality of different size gauge ball rings in order according to the diameter size of the gauge ball ring; based on the diameter size order of the gauge ball ring, matching a to-be-detected axle fork with one of the plurality of gauge ball rings in order to obtain a target gauge ball ring matched with the to-be-detected axle fork; obtaining a target ball ring with the same diameter as the target gauge ball ring; and assembling the target ball ring with the to-be-detected axle fork.

[0008] According to the technical means, the to-be-detected axle fork can be matched with the target gauge ball ring in sequence, and the target ball ring with the same diameter as the target gauge ball ring is obtained. In this way, the diameter of the ball ring matched with the to-be-detected axle fork can be determined through the gauge ball ring, and the target ball ring matched with the to-be-detected axle fork is obtained. The to-be-detected axle fork and the target ball ring are assembled. The circumferential gap between the to-be-detected axle fork and the ball ring is small. In this way, the plurality of to-be-detected axle forks are operated according to the above steps, and the plurality of to-be-detected axle forks can be assembled with the ball rings matched with them and the assembly circumferential gap is small, thereby improving the yield of the three-pin assembly.

[0009] In a possible implementation, the diameter size order of the gauge ball ring includes that the plurality of gauge ball rings are arranged in ascending order.

[0010] According to the technical means, the to-be-detected axle fork can be matched with the target gauge ball ring in sequence, and the target ball ring with the same diameter as the target gauge ball ring is obtained. In this way, the diameter of the ball ring matched with the to-be-detected axle fork can be determined through the gauge ball ring, and the target ball ring matched with the to-be-detected axle fork is obtained. The to-be-detected axle fork and the target ball ring are assembled. The circumferential gap between the to-be-detected axle fork and the ball ring is small. In this way, the plurality of to-be-detected axle forks are operated according to the above steps, and the plurality of to-be-detected axle forks can be assembled with the ball rings matched with them and the assembly circumferential gap is small, thereby improving the yield of the three-pin assembly.

[0011] In a possible implementation, the target gauge ball ring matched with the to-be-detected axle fork includes that if the i th gauge ball ring arranged in ascending order matches the to-be-detected axle fork, whether the i+1 th gauge ball ring arranged in ascending order matches the to-be-detected axle fork is determined. If not, the i th gauge ball ring is determined as the target gauge ball ring.

[0012] According to the technical means, if the i th gauge ball ring arranged in ascending order matches the to-be-detected axle fork, whether the i+1 th gauge ball ring arranged in ascending order matches the to-be-detected axle fork is determined. If not, the i th gauge ball ring is determined as the target gauge ball ring. If yes, the above steps are repeated. In this way, the gauge ball ring matched with the to-be-detected axle fork and having the smallest gap value can be found from the plurality of gauge ball rings, which is beneficial to reduce the circumferential gap between the to-be-detected axle fork and the ball ring and improve the yield of the three-pin assembly.

[0013] In a possible implementation, the i th gauge ball ring matches the to-be-detected axle fork, including moving the to-be-detected axle fork to the i th gauge ball ring under the action of gravity. If the inner bottom surface of the to-be-detected axle fork can contact the i th gauge ball ring, the i th gauge ball ring matches the to-be-detected axle fork.

[0014] According to the technical means, the detection shaft fork moves to the i th detection ball ring under the action of gravity, and if the bottom of the detection shaft fork can contact the i th detection ball ring, the i th detection ball ring matches the detection shaft fork. It can be understood that if the inner bottom surface of the detection shaft fork can contact the detection ball ring, it means that the target ball ring with the same diameter as the detection ball ring can be assembled into the detection shaft fork, so as to ensure that the target ball ring and the detection shaft fork can be normally assembled and used after assembly.

[0015] In a possible implementation, the detection ball ring diameter size order includes that the plurality of detection ball rings are arranged in descending order.

[0016] According to the technical means, the detection shaft fork can be matched with the plurality of ball rings arranged in descending order in sequence to obtain the target detection ball ring matched with the detection shaft fork.

[0017] In a possible implementation, obtaining the target detection ball ring matched with the detection shaft fork includes: judging whether the m th detection ball ring matches the detection shaft fork according to the descending order; if yes, the m th detection ball ring is determined as the target detection ball ring.

[0018] According to the technical means, the detection ball ring matched with the detection shaft fork and having the minimum gap value can be directly found from the plurality of detection ball rings, which is beneficial to reduce the circumferential gap between the detection shaft fork and the ball ring and improve the yield of the three-pin assembly.

[0019] In a possible implementation, the diameters of the plurality of detection ball rings are arranged in an arithmetic progression.

[0020] According to the technical means, if the diameters of the plurality of detection ball rings are arranged in an arithmetic progression, the diameter of a certain detection ball ring cannot match the detection shaft fork, and the diameter of the next detection ball ring is larger than the circumferential gap value of the detection shaft fork, so as to further improve the yield of the three-pin assembly.

[0021] According to the second aspect, a control device for a driving shaft assembly circumferential gap is provided, including: a processing unit and an acquisition unit, the processing unit is used for arranging a plurality of detection ball rings of different sizes in order according to the detection ball ring diameter size order; the acquisition unit is used for matching a detection shaft fork with one of the plurality of detection ball rings in order based on the detection ball ring diameter size order, and obtaining a target detection ball ring matched with the detection shaft fork; the acquisition unit is also used for obtaining a target ball ring with the same diameter as the target detection ball ring; and the processing unit is also used for assembling the target ball ring with the detection shaft fork.

[0022] In a possible implementation, the acquisition unit is specifically configured to: if the ith gauge ball ring arranged in the ascending order matches the to-be-detected axle fork, determine whether the (i+1)th gauge ball ring arranged in the ascending order matches the to-be-detected axle fork; if not, determine that the ith gauge ball ring is the target gauge ball ring.

[0023] In a possible implementation, the acquisition unit is further specifically configured to: move the to-be-detected axle fork to the ith gauge ball ring under the action of gravity, and if the bottom of the to-be-detected axle fork can contact the ith gauge ball ring, the ith gauge ball ring matches the to-be-detected axle fork.

[0024] Therefore, the above technical features of the present application have the following beneficial effects:

[0025] (1) The present application can match the to-be-detected axle fork with one of the plurality of gauge ball rings in order of the diameter of the gauge ball ring, acquire the target gauge ball ring matched with the to-be-detected axle fork, and acquire the target ball ring with the same diameter as the target gauge ball ring. In this way, the diameter of the ball ring matched with the to-be-detected axle fork can be determined by the gauge ball ring, the target ball ring matched with the to-be-detected axle fork is acquired, and the to-be-detected axle fork is assembled with the target ball ring. The to-be-detected axle fork has a small circumferential gap with the ball ring. In this way, a plurality of to-be-detected axle forks are operated according to the above steps, and the plurality of to-be-detected axle forks can be assembled with the ball rings matched with them and have a small assembly circumferential gap, thereby improving the yield of the three-pin assembly.

[0026] (2) If the ith gauge ball ring arranged in the ascending order matches the to-be-detected axle fork, it is determined whether the (i+1)th gauge ball ring arranged in the ascending order matches the to-be-detected axle fork. If not, the ith gauge ball ring is determined to be the target gauge ball ring. If yes, the above steps are repeated. In this way, the gauge ball ring matched with the to-be-detected axle fork and having the smallest gap value can be found from the plurality of gauge ball rings, which is beneficial to reduce the circumferential gap between the to-be-detected axle fork and the ball ring and improve the yield of the three-pin assembly.

[0027] (3) The to-be-detected axle fork can be moved to the ith gauge ball ring under the action of gravity. If the bottom of the to-be-detected axle fork can contact the ith gauge ball ring, the ith gauge ball ring matches the to-be-detected axle fork. It can be understood that if the inner bottom surface of the to-be-detected axle fork can contact the gauge ball ring, it indicates that the target ball ring with the diameter of the gauge ball ring can be assembled into the to-be-detected axle fork, so as to ensure that the target ball ring and the to-be-detected axle fork can be normally assembled and used after assembly.

[0028] (4) The diameters of the plurality of gauge ball rings of the present application are arranged in an arithmetic progression, so that the diameter of a certain gauge ball ring cannot match the shaft fork to be detected, and the diameter of a next-level gauge ball ring matches the shaft fork to be detected with a larger circumferential gap value, so as to further improve the yield of the three-pin assembly.

[0029] It should be noted that the technical effects brought by any implementation manner of the second aspect can refer to the technical effects brought by the corresponding implementation manner in the first aspect, which will not be repeated here.

[0040] In order to make the ordinary person skilled in the art better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings.

[0041] The terms "first" and "second" and the like in the description of the present application and the drawings are used to distinguish different objects, and are not used to describe a specific order of the objects, for example, the first distance and the second distance are used to distinguish different distances, and are not used to describe a specific order of the distances.

[0042] In addition, the terms "comprising" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally further include other steps or units not listed, or can optionally further include other steps or units inherent to the process, method, product or device.

[0043] It should be noted that in the embodiments of the present application, the words "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of "exemplary" or "for example" is intended to present the relevant concept in a specific manner.

[0044] In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0045] It can be understood that the three-pin joint assembly gap value generated after the shaft fork and the ball ring are assembled is the most critical control factor among several factors affecting the circumferential gap value of the drive shaft assembly. The three-pin joint assembly gap value must be controlled within a reasonable range, and a large gap value will cause the drive shaft assembly to be loose. The shaft fork is made of precision forging process. Due to the limitation of process conditions, when the ball channel is processed, the diameter of the ball channel cannot reach a very high accurate value, and the diameter of the processed ball channel is in a large range. Therefore, it is impossible to directly achieve the requirement of circumferential gap through ball channel size design and ball channel processing.

[0046] As Figure 1 , Figure 2 and Figure 3As shown, the axle fork 1 is made by using the precision forging process. Due to the process condition limitation, when the axle fork 1 is processed, the diameter of the axle fork 1 cannot reach a very high accurate value, and the inner cylinder diameter range of the processed axle fork 1 is large. Therefore, the requirement of the circumferential clearance cannot be achieved by the size design of the axle fork 1 and the inner cylinder processing of the axle fork 1. The ball ring 2 is processed by using the grinding process, and the size accuracy can be controlled to be very high and accurate. When processing, several batches of ball rings with different diameters can be ground according to the actual requirements, that is, ball rings with different gears.

[0047] After the ball ring 2 is installed in the inner cylinder of the axle fork 1, in order to ensure that there is no jamming and interference during operation, the relationship between the two is designed as a clearance fit. Because the diameter of the ball ring 2 is a range value, the diameter of the inner cylinder of the axle fork 1 is also a range value. If the precision forged axle fork 1 and the ball ring 2 are randomly paired and assembled, there may be a large clearance value. For example, the axle fork 1 with the upper limit of the design value of the inner cylinder diameter is assembled with the ball ring 2 with the lower limit of the design value of the diameter. The clearance value of the three-pin joint assembly after assembly will be larger, which will exceed the designed desired assembly clearance value, and an unqualified three-pin joint assembly is produced.

[0048] Based on this, the embodiment of the present application provides a control method and device for the circumferential clearance of the drive shaft assembly, which can enable multiple axle forks to be assembled with ball rings matched therewith and the circumferential clearance of the assembled assembly to be small, thereby improving the yield of the produced three-pin assembly.

[0049] In order to facilitate understanding, the control method for the circumferential clearance of the drive shaft assembly provided by the present application is specifically introduced below in combination with the drawings.

[0050] Figure 4 is a flow chart of the control method for the circumferential clearance of the drive shaft assembly provided by the embodiment of the present application, as Figure 4 shown, the control method for the circumferential clearance of the drive shaft assembly can include steps S101-S104.

[0051] S101, arrange multiple different size gauge ball rings in order of gauge ball ring diameter size.

[0052] It can be understood that the multiple different size gauge ball rings refer to the diameters of the multiple gauge ball rings being different. For example, the diameters of the multiple gauge ball rings can be 5.01 mm, 5.04 mm, 5.07 mm, and the like. The present application does not limit this.

[0053] In addition, specifically, the multiple gauge ball rings can be 6 gauge ball rings, 4 gauge ball rings, or 7 gauge ball rings, and the present application does not limit this.

[0054] In one possible implementation, the order of the gauge ball ring diameter size includes that the multiple gauge ball rings are arranged in order from small to large.

[0055] For example, the four gauge ball rings have diameters of 6.01, 6.07, 6.05, and 6.09, and the four gauge ball rings are arranged in the order of 6.01, 6.05, 6.07, and 6.09.

[0056] In this way, the to-be-tested axle fork can be matched with the multiple ball rings arranged in the order from small to large one by one, so as to obtain the target gauge ball ring matched with the to-be-tested axle fork.

[0057] In another possible implementation, the order of the diameters of the gauge ball rings includes that the multiple gauge ball rings are arranged in the order from large to small.

[0058] For example, the six gauge ball rings have diameters of 7.01, 7.07, 7.11, 7.09, 7.03, and 7.15, and the six gauge ball rings are arranged in the order of 7.01, 7.03, 7.07, 7.09, 7.11, and 7.15.

[0059] In this way, the to-be-tested axle fork can be matched with the multiple ball rings arranged in the order from large to small one by one, so as to obtain the target gauge ball ring matched with the to-be-tested axle fork.

[0060] In some embodiments, the diameters of the multiple gauge ball rings are arranged in an arithmetic progression. For example, the six gauge ball rings have diameters of 7.01, 7.03, 7.05, 7.07, 7.09, and 7.11.

[0061] In this way, when the diameters of the multiple gauge ball rings are arranged in an arithmetic progression, it can be avoided that the diameter of a certain gauge ball ring cannot be matched with the to-be-tested axle fork, and the diameter of the next gauge ball ring is larger than the circumferential gap value of the to-be-tested axle fork. In this way, the yield of the three-pin assembly is further improved.

[0062] S102, based on the order of the diameters of the gauge ball rings, the to-be-tested axle fork is matched with one of the multiple gauge ball rings one by one.

[0063] In a possible implementation, the matching of the to-be-tested axle fork with the gauge ball ring refers to that the to-be-tested axle fork is moved to the gauge ball ring under the action of gravity, and if the inner bottom surface of the to-be-tested axle fork can contact the gauge ball ring, the gauge ball ring is matched with the to-be-tested axle fork.

[0064] Specifically, during the matching process between the fork and the gauge ball ring, hold the fork handle with the ball track facing down and align it with the roller on the gauge ball ring. Lower the fork vertically. If it gets stuck, straighten the fork and let it move downwards under gravity. If the ball track of the fork can fall freely and the bottom surface of the fork's cylinder can contact the gauge ball ring, then the fork is matched with the gauge ball ring.

[0065] In this way, when jamming occurs, the shaft fork is straightened first, and the shaft fork moves downward under the action of gravity. This can prevent the bottom surface of the shaft fork from not being able to contact the gauge ball ring due to tilting, which would result in a large gap between the target gauge ball ring matched with the shaft fork and the shaft fork, affecting the yield of the three-pin assembly.

[0066] It is understandable that if the bottom surface of the cylinder of the shaft fork to be tested can contact the gauge ball ring, it means that the target ball ring with the diameter of the gauge ball ring can be assembled into the shaft fork to be tested. This ensures that the target ball ring and the shaft fork to be tested can be properly assembled and can be used normally after assembly.

[0067] S103. Obtain the target gauge ball ring that matches the shaft fork to be inspected.

[0068] In some embodiments, such as Figure 5 As shown, step S103, obtaining the target gauge ball ring that matches the shaft fork to be tested, may include:

[0069] S1031a. If the i-th gauge ball ring arranged in ascending order matches the shaft fork to be tested, then determine whether the (i+1)-th gauge ball ring arranged in ascending order matches the shaft fork to be tested.

[0070] S1031b1. If not, then determine the i-th fixture ball ring as the target fixture ball ring.

[0071] S1031b2, If yes, then determine whether the i+2 gauge ball rings match the shaft fork to be tested;

[0072] S1031b3. If the (i+2)th gauge ball ring does not match the shaft fork to be inspected, then the (i+1)th gauge ball ring is determined as the target gauge ball ring.

[0073] For example, if the first ball ring (i.e., the smallest diameter gauge ball ring) in the order from small to large matches the shaft fork to be detected, it is determined whether the second gauge ball ring in the order from small to large matches the shaft fork to be detected. If not, the first gauge ball ring is determined to be the target gauge ball ring. If yes, it is determined whether the third gauge ball ring in the order from small to large matches the shaft fork to be detected. If yes, the second gauge ball ring is determined to be the target gauge ball ring. If yes, it is determined whether the fourth gauge ball ring in the order from small to large matches the shaft fork to be detected, and so on until the target gauge ball ring is determined.

[0074] In this way, the gauge ball ring that matches the shaft fork to be detected and has the smallest gap value can be found from the plurality of gauge ball rings, which is conducive to reducing the circumferential gap between the shaft fork to be detected and the ball ring and improving the yield of the three-pin assembly.

[0075] In other embodiments, as shown in FIG. 10, the step S103 of obtaining the target gauge ball ring that matches the shaft fork to be detected can include: Figure 6

[0076] S1032a, determining whether the mth gauge ball ring matches the shaft fork to be detected in the order from large to small;

[0077] S1032b1, if yes, determining the mth gauge ball ring to be the target gauge ball ring;

[0078] S1032b2, if not, determining whether the (m+1)th gauge ball ring matches the shaft fork to be detected. S1032b3, if the (m+1)th gauge ball ring matches the shaft fork to be detected, determining the (m+1)th gauge ball ring to be the target gauge ball ring;

[0079] For example, it is determined whether the first gauge ball ring (i.e., the largest diameter gauge ball ring) matches the shaft fork to be detected in the order from large to small. If yes, the first gauge ball ring is determined to be the target gauge ball ring. If not, it is determined whether the second gauge ball ring matches the shaft fork to be detected. If yes, the second gauge ball ring is determined to be the target gauge ball ring. If not, it is determined whether the third gauge ball ring matches the shaft fork to be detected, and so on until the target gauge ball ring is determined.

[0080] In this way, the gauge ball ring that matches the shaft fork to be detected and has the smallest gap value can be directly found from the plurality of gauge ball rings, which is conducive to reducing the circumferential gap between the shaft fork to be detected and the ball ring and improving the yield of the three-pin assembly.

[0081] S104, obtaining a target ball ring with the same diameter as the target gauge ball ring, and assembling the target ball ring with the shaft fork to be detected.

[0082] ​Optionally, the target ball ring with the same diameter as the target gauge ball ring can be obtained by searching for a ball ring with the same diameter as the target gauge ball ring from the already produced ball rings, and the ball ring is taken as the target ball ring.

[0083] Optionally, the target ball ring with the same diameter as the target gauge ball ring can also be obtained by producing a ball ring with the same diameter as the target gauge ball ring, and the produced ball ring is taken as the target ball ring.

[0084] In this way, the target gauge ball ring matched with the to-be-tested axle fork can be obtained by sequentially matching the to-be-tested axle fork with one of the plurality of gauge ball rings based on the diameter size order of the gauge ball rings, and the target ball ring with the same diameter as the target gauge ball ring is obtained. In this way, the diameter of the ball ring matched with the to-be-tested axle fork can be determined by the gauge ball ring, and the target ball ring matched with the to-be-tested axle fork is obtained, and the to-be-tested axle fork is assembled with the target ball ring. The circumferential gap between the to-be-tested axle fork and the ball ring is small. In this way, the plurality of to-be-tested axle forks are operated according to the above steps, and the plurality of to-be-tested axle forks can be assembled with the ball rings matched with the to-be-tested axle forks and the assembly circumferential gap is small, thereby improving the yield of the produced three-pin assembly.

[0090] Optionally, the acquisition unit 102 can be specifically configured to determine whether an (i+1)th gauge ball ring arranged in order from small to large matches the shaft fork to be detected if an ith gauge ball ring arranged in order from small to large matches the shaft fork to be detected, and determine the ith gauge ball ring as the target gauge ball ring if not.
