Description

Technical Field

[0001] The utility model relates to the technical field of clutch drive discs, in particular to a wear-resistant single drive disc. Background Art

[0002] The drive plate is an important component of the new clutch, which is used to transmit the engine torque and receive the clamping force of the actuator on the clutch. It is used in a variety of dual clutches. At present, in order to reduce costs, it is usually considered to remove the torsional damper, which also requires the drive plate structure to bear and transmit almost all the engine torque and indirectly bear all the actuator clamping force. Therefore, the performance requirements for the drive plate are also higher.

[0003] The patent with publication number CN213419716U discloses a clutch drive plate, including a drive plate body and a plurality of transmission connecting pins; the drive plate body is loaded between a dual-mass flywheel and a dual clutch body; an axial hole is provided at the center of the drive plate body for installing a transmission shaft, and a plurality of openings are radially provided around the axial hole, and a plurality of reinforcing ribs are provided on at least one side of the drive plate body and are distributed alternately with the openings; each of the openings is provided with a first groove portion connected to the opening at a side edge position on one side of the radial center line of the drive plate body along the rotation direction of the drive plate body; the clutch drive plate described in the present application has the functions of weight reduction, ventilation and anti-deformation, and can better meet the requirements of high performance and economic performance of the dual clutch system.

[0004] Although the above-mentioned prior art has the functions of weight reduction, ventilation and anti-deformation, since a plurality of openings are opened on the driving disc body, the overall strength of the driving disc body is reduced, and the contact surface with the driven disc is greatly reduced, resulting in the driving disc body being more susceptible to wear, thereby reducing the service life of the driving disc body, and requiring overall replacement after wear, which is not conducive to long-term use. In view of this, we propose a wear-resistant single driving disc. Utility Model Content

[0005] The purpose of the utility model is to provide a wear-resistant single drive disc to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

When the special-shaped wear-resistant sheet is severely worn, it can be replaced, avoiding the overall replacement of the drive disk and reducing maintenance costs. The two adjacent special-shaped connecting seats and the drive disk form an air inlet channel. When the drive disk rotates, airflow can be generated in the air inlet channel, thereby playing a role in heat dissipation and avoiding accelerated wear of the special-shaped wear-resistant sheet due to excessively high temperature during operation.

[0008] Preferably, the outer side, inner side and both sides of the special-shaped connecting seat are arc-shaped structures, the outer side of the special-shaped connecting seat is a part of a first arc, the inner side of the special-shaped connecting seat is a part of a second arc, and the diameter of the first arc is greater than the diameter of the second arc.

The air inlet of the arc-shaped ventilation groove is larger than the air outlet of the arc-shaped ventilation groove, and has the same function as the air inlet channel, and can play a good role in heat dissipation.

The two ends of the circular hole b are respectively connected to the threaded groove and the circular hole a, and the rectangular connecting block is fixed in the rectangular connecting port by the long bolt, thereby facilitating the staff to disassemble and assemble the special-shaped wear-resistant plate.

[0013] Preferably, the special-shaped wear-resistant sheet comprises a wear-resistant sheet body, an oxide film is provided on the outer side of the wear-resistant sheet body, and a wear-resistant layer is provided on the front side of the oxide film.

[0015] The wear-resistant sheet body is made of 7075-T6 aluminum alloy. The surface is anodized to form a dense oxide film, and then a silicon carbide wear-resistant layer is evenly coated on the oxide film through chemical vapor deposition technology. The thickness of the wear-resistant layer is selected according to actual conditions, and the thickness range is 0.1-1mm. This wear-resistant layer can not only effectively improve the wear resistance and corrosion resistance of the drive disc, but also due to the characteristics of silicon carbide materials, it also has good thermal stability, ensuring the stable performance of the drive disc under high-speed operation conditions.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The shape of the wear-resistant single drive disc and the special-shaped wear-resistant sheet are adapted to the shape of the special-shaped connecting seat. A rectangular connecting block is provided on the rear side of the special-shaped wear-resistant sheet. The rectangular connecting block is detachably connected to the rectangular connecting port by a long bolt, so that the special-shaped wear-resistant sheet can be installed on the rectangular connecting block.

When the single drive disc rotates, airflow can be generated in the air inlet channel and the arc-shaped ventilation grooves, thereby playing a role in heat dissipation and avoiding accelerated wear of the special-shaped wear-resistant sheet due to excessive temperature during operation.

[0019] 3. The wear-resistant drive disc is made of 7075-T6 aluminum alloy. The surface is anodized to form a dense oxide film, and then a silicon carbide wear-resistant layer is evenly coated on the oxide film through chemical vapor deposition technology.

[0028] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0029] A wear-resistant drive disk single disk, comprising a drive disk single disk 1, an axial hole 10 for installing a transmission shaft is opened in the middle of the front side of the drive disk single disk 1, a plurality of connection holes 11 for installing a transmission connecting pin are opened on the front side of the drive disk single disk 1 and close to the outer edge, a plurality of special-shaped connecting seats 2 arranged in a circular array are arranged on the front side of the drive disk single disk 1, a rectangular connecting port 20 is opened on the front side of the special-shaped connecting seat 2, a detachable special-shaped wear-resistant sheet 3 is provided on the front side of the special-shaped connecting seat 2, the shape of the special-shaped wear-resistant sheet 3 is adapted to the shape of the special-shaped connecting seat 2, and the special-shaped wear-resistant sheet 3 is provided on the front side of the special-shaped connecting seat 2. A rectangular connecting block 33 is provided on the rear side of 3, and the rectangular connecting block 33 is detachably connected to the rectangular connecting port 20 by a long bolt 4, so that the special-shaped wear-resistant sheet 3 can be installed on the rectangular connecting block 33, and can be replaced when the special-shaped wear-resistant sheet 3 is severely worn, avoiding the overall replacement of the drive disk single disk 1 and reducing maintenance costs. The two adjacent special-shaped connecting seats 2 and the drive disk single disk 1 form an air inlet channel 5. When the drive disk single disk 1 rotates, airflow can be generated in the air inlet channel 5, thereby playing a role in heat dissipation, avoiding the accelerated wear of the special-shaped wear-resistant sheet 3 due to excessively high temperature during operation.

[0030] In this embodiment, the outer side, inner side and both sides of the special-shaped connecting seat 2 are all arc-shaped structures. The outer side of the special-shaped connecting seat 2 is a part of the first arc, and the inner side of the special-shaped connecting seat 2 is a part of the second arc. The diameter of the first arc is greater than the diameter of the second arc.

[0031] Specifically, the outer end of the air inlet channel 5 is the air inlet, the inner end of the air inlet channel 5 is the air outlet, and the air inlet of the air inlet channel 5 is larger than the air outlet of the air inlet channel 5. The arc structures on both sides of the special-shaped connecting seat 2 are different, thereby forming an air inlet channel 5 with a larger air inlet, which is conducive to the entry of air into the air inlet channel 5 when the driving disk single disk 1 rotates.

[0032] Furthermore, arc-shaped ventilation grooves 22 are provided on the front side and near the two sides of the special-shaped connecting seat 2. The air inlet of the arc-shaped ventilation groove 22 is larger than the air outlet of the arc-shaped ventilation groove 22, and has the same function as the air inlet channel 5, and can play a good role in heat dissipation. When airflow is generated in the arc-shaped ventilation groove 22, it can quickly dissipate the heat for the special-shaped wear-resistant plate 3.

[0033] Furthermore, a threaded groove 201 for threaded connection of the long bolt 4 is provided on the inner wall of the rectangular connecting port 2 and close to the inner side of the special-shaped connecting seat 2, a circular hole a200 for the long bolt 4 to pass through is provided on the inner wall of the rectangular connecting port 2 and close to the outer side of the special-shaped connecting seat 2, and a circular groove 21 for accommodating the head of the long bolt 4 is provided on the outer side of the special-shaped connecting seat 2 to prevent the head of the long bolt 4 from protruding from the outer side of the special-shaped connecting seat 2.

[0034] Furthermore, a circular hole b330 is opened on the side of the rectangular connecting block 33 for the long bolt 4 to pass through. The rectangular connecting block 33 is inserted into the rectangular connecting port 20. The two ends of the circular hole b330 are respectively connected to the threaded groove 201 and the circular hole a200. The rectangular connecting block 33 is fixed in the rectangular connecting port 20 by the long bolt 4, thereby facilitating the staff to disassemble and assemble the special-shaped wear-resistant plate 3.

[0035] Furthermore, the special-shaped wear-resistant sheet 3 comprises a wear-resistant sheet body 30 , an oxide film 31 is disposed on the outer side of the wear-resistant sheet body 30 , and a wear-resistant layer 32 is disposed on the front side of the oxide film 31 .

[0036] Furthermore, the wear-resistant sheet body 30 is made of 7075-T6 aluminum alloy, the oxide film 31 is formed by anodizing the surface of the wear-resistant sheet body 30, and the wear-resistant layer 32 is made of silicon carbide material;

[0037] The wear-resistant plate body 30 is made of 7075-T6 aluminum alloy, and the surface is anodized to form a dense oxide film 31, and then a silicon carbide wear-resistant layer 32 is evenly coated on the oxide film 31 through chemical vapor deposition technology. The thickness of the wear-resistant layer 32 is selected according to actual conditions, and the thickness range is 0.1-1mm. The wear-resistant layer 32 can not only effectively improve the wear resistance and corrosion resistance of the drive disc, but also due to the characteristics of silicon carbide material, it also has good thermal stability, ensuring the stable performance of the drive disc under high-speed operation conditions.

[0038] When the wear-resistant drive disk single disk of this embodiment is in use, when the driven disk contacts and generates friction with the drive disk, the wear-resistant layer 32 made of silicon carbide material can effectively improve the wear resistance of the drive disk single disk 1. When the drive disk single disk 1 rotates, airflow can be generated in the air inlet channel 5 and the arc-shaped ventilation groove 22, thereby playing a role in heat dissipation, and avoiding the accelerated wear of the special-shaped wear-resistant plate 3 due to excessive temperature during operation; when the special-shaped wear-resistant plate 3 is severely worn and needs to be replaced, the staff will remove all the long bolts 4, and then pull the special-shaped wear-resistant plate 3 forward to move the rectangular connecting block 33 out of the rectangular connecting port 20, thereby realizing the removal of the special-shaped wear-resistant plate 3, and then the staff will insert the rectangular connecting block 33 of the new special-shaped wear-resistant plate 3 into the rectangular connecting port 20, and use the long bolts 4 to fix the rectangular connecting block 33 in the rectangular connecting port 20, thereby realizing the replacement of the special-shaped wear-resistant plate 3, avoiding the overall replacement of the drive disk single disk 1, and reducing maintenance costs.
