Description

Technical Field

[0001] The utility model belongs to the technical field of a spline hub, and more specifically, particularly relates to a high-efficiency and wear-resistant automobile clutch spline hub structure. Background Art

[0002] The clutch spline hub is a key component in the clutch system, which connects the clutch plate and the transmission input shaft to transmit power through a spline connection.

[0003] Based on the above, the inventors have found the following problems: most of the current splines are integrated on the output shaft, and when they need to be replaced, they need to be replaced as a whole, which results in high replacement costs.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an efficient and wear-resistant automobile clutch spline hub structure is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a high-efficiency and wear-resistant automobile clutch spline hub structure to solve the problem of high cost when replacing the current splines.

[0006] The purpose and effect of the utility model of high-efficiency wear-resistant automobile clutch spline hub structure are achieved by the following specific technical means:

[0007] An efficient and wear-resistant automobile clutch spline hub structure comprises an output shaft and a driven plate installed on a gearbox, a spline hub is installed on the surface of the driven plate, a spline is installed on the surface of the output shaft, a first limiting groove is provided on the surface of the output shaft, a first limiting block is installed on the surface of the spline, the first limiting block matches the first limiting groove, a portion of the first limiting block extends beyond the spline, a first threaded hole is provided on the surface of the portion of the first limiting block extending beyond the spline and in the first limiting groove, and a first bolt is installed in the first threaded hole.

[0008] Furthermore, the surface of the driven plate is provided with a through hole matching the spline hub, a second limiting groove is provided in the through hole, a second limiting block is installed on the surface of the spline hub, and second threaded holes are provided on the surfaces of the driven plate and the second limiting block, and a second bolt is installed in the second threaded hole.

[0009] Furthermore, the second limiting groove, the second limiting block, the second threaded hole and the second bolt form a combination, and there are multiple of the combination, which are evenly distributed on the spline hub and the driven plate.

[0010] Furthermore, the length of the first limiting groove is greater than the sum of the lengths of the spline and the spline hub.

[0011] Furthermore, the spline and the spline hub have different tooth number models.

[0012] Furthermore, the material of the spline and the spline hub is high carbon steel.

[0013] Furthermore, the material of the spline and the spline hub is alloy steel.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model cooperates with the first limiting groove, the first limiting block, the first threaded hole and the first bolt in the use. When the spline needs to be replaced, it is only necessary to remove the driven plate and the spline hub, and then unscrew the first bolt, and then the spline can be removed, and then a new spline is replaced. Then, the first limiting block of the spline is aligned with the first limiting groove for assembly. When the first threaded hole of the first limiting block is aligned with the first threaded hole in the first limiting groove, the first bolt is tightened. Through the above design, only the spline can be replaced without replacing the output shaft, thereby reducing the replacement cost.

[0016] Through the coordinated use of the through hole, the second limiting groove, the second limiting block, the second threaded hole and the second bolt, when the spline hub needs to be replaced, it is only necessary to separate the driven plate from the spline, then unscrew the second bolt, then remove the spline hub, and then replace the new spline hub, and then align the second limiting block with the second limiting groove for assembly, and then tighten the second bolt to complete the assembly of the spline hub. Through the above design, the spline hub can be replaced quickly, which improves practicality.

[0017] By limiting the length of the first limit groove, when the spline and the spline hub need to be lubricated, it is only necessary to unscrew the first bolt and then move the spline backward, and then add lubricating paste to the spline. When the adjustment is completed, the spline can be reset. Through the above design, the operation of adding lubricating paste can be completed without removing the driven disk, thereby improving the convenience of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example:

[0030] As attached Figure 1 To Attachment Figure 6 As shown:

[0031] The utility model provides a high-efficiency and wear-resistant automobile clutch spline hub structure, comprising an output shaft 1 and a driven plate 2 installed on a gearbox, a spline hub 3 is installed on the surface of the driven plate 2, a spline 4 is installed on the surface of the output shaft 1, a first limiting groove 5 is provided on the surface of the output shaft 1, a first limiting block 6 is installed on the surface of the spline 4, the first limiting block 6 and the first limiting groove 5 match, a part of the first limiting block 6 exceeds the spline 4, a first threaded hole 7 is provided on the surface of the part of the first limiting block 6 exceeding the spline 4 and in the first limiting groove 5, and a first bolt 8 is installed in the first threaded hole 7.

[0032] Through the coordinated use of the first limiting groove 5, the first limiting block 6, the first threaded hole 7 and the first bolt 8, when the spline 4 needs to be replaced, it is only necessary to remove the driven plate 2 and the spline hub 3, and then unscrew the first bolt 8, and then the spline 4 can be removed, and then a new spline 4 is replaced, and then the first limiting block 6 of the spline 4 is aligned with the first limiting groove 5 for assembly, and when the first threaded hole 7 of the first limiting block 6 is aligned with the first threaded hole 7 in the first limiting groove 5, the first bolt 8 is tightened. Through the above design, only the spline 4 can be replaced without replacing the output shaft 1, thereby reducing the replacement cost.

[0033] Among them, the surface of the driven plate 2 is provided with a through hole 9 matching the spline hub 3, a second limiting groove 10 is opened in the through hole 9, a second limiting block 11 is installed on the surface of the spline hub 3, and the surfaces of the driven plate 2 and the second limiting block 11 are both provided with a second threaded hole 12, and a second bolt 13 is installed in the second threaded hole 12.

[0034] Through the coordinated use of the through hole 9, the second limiting groove 10, the second limiting block 11, the second threaded hole 12 and the second bolt 13, when the spline hub 3 needs to be replaced, it is only necessary to separate the driven plate 2 from the spline 4, then unscrew the second bolt 13, and then remove the spline hub 3, and then replace the new spline hub 3, and then align the second limiting block 11 with the second limiting groove 10 for assembly, and then tighten the second bolt 13 to complete the assembly of the spline hub 3. Through the above design, the spline hub 3 can be replaced quickly, thereby improving practicality.

[0035] The second limiting groove 10 , the second limiting block 11 , the second threaded hole 12 and the second bolt 13 are a combination, and there are multiple of the combination, which are evenly distributed on the spline hub 3 and the driven plate 2 .

[0036] Through the design of multiple combinations, the spline hub 3 can be installed more stably.

[0037] The length of the first limiting groove 5 is greater than the sum of the lengths of the spline 4 and the spline hub 3 .

[0038] By limiting the length of the first limit groove 5, when the spline 4 and the spline hub 3 need to be lubricated, it is only necessary to unscrew the first bolt 8, and then move the spline 4 backward, and then add lubricating grease to the spline 4. When the adjustment is completed, the spline 4 can be reset. Through the above design, the operation of adding lubricating grease can be completed without removing the driven disk 2, thereby improving the convenience of use.

[0039] The spline 4 and the spline hub 3 have different numbers of teeth.

[0040] By using splines 4 and spline hubs 3 with different numbers of teeth, when high-speed operation is required, the splines 4 and spline hubs 3 with fewer teeth can be replaced to increase the torque. When the service life needs to be increased, the splines 4 and spline hubs 3 with more teeth can be replaced. The splines 4 with more teeth can distribute the torque over a larger contact area, thereby reducing the load borne by each tooth, which helps durability.

[0041] Wherein, the material of the spline 4 and the spline hub 3 is high carbon steel.

[0042] High carbon steel has higher hardness and strength due to its higher carbon content, which improves wear resistance while being lower in cost.

[0043] Wherein, the material of the spline 4 and the spline hub 3 is alloy steel.

[0044] By adding alloying elements, alloy steel can have high toughness while maintaining high strength. At the same time, different mechanical properties and physical properties can be obtained by adjusting the types and proportions of alloying elements.

[0045] The specific usage and function of this embodiment are as follows:

[0046] When the utility model is in use, when the spline 4 needs to be replaced, it is only necessary to remove the driven plate 2 and the spline hub 3, and then unscrew the first bolt 8, and then the spline 4 can be removed, and then replace the new spline 4, and then align the first limit block 6 of the spline 4 with the first limit groove 5 for assembly, and when the first threaded hole 7 of the first limit block 6 is aligned with the first threaded hole 7 in the first limit groove 5, tighten the first bolt 8. When the spline hub 3 needs to be replaced, it is only necessary to separate the driven plate 2 from the spline 4, and then unscrew the second bolt 13, and then remove the spline hub 3, and then replace the new spline hub 3, and then align the second limit block 11 with the second limit groove 10 for assembly, and then tighten the second bolt 13 to complete the assembly of the spline hub 3. Through the above design, only the spline 4 can be replaced without replacing the output shaft 1, and the spline hub 3 can be quickly replaced, which reduces the replacement cost.
