Description

Technical Field

[0001] This utility model relates to the field of clutch drive disc technology, and in particular to a clutch drive disc. Background Technology

[0002] In mechanical transmission systems, the clutch, as a crucial component connecting the engine and gearbox, undertakes the key task of power transmission and disconnection. Its working principle involves the interaction of friction materials with the metal materials of the pressure plate and flywheel, generating static friction under pressure. This smoothly transmits engine torque to the gearbox, achieving effective power transmission and control. Clutches are widely used in automobiles, motorcycles, and various industrial machinery, serving as a core component ensuring normal equipment operation and enabling smooth gear shifting and starting.

[0003] To this end, the specification of patent CN213419716U discloses a clutch drive disc, including a drive disc body and multiple transmission connecting pins; the drive disc body is mounted between a dual-mass flywheel and a dual-clutch body; the drive disc body has a shaft hole at its center for mounting a transmission shaft, and multiple openings are radially arranged around the shaft hole; the drive disc body has multiple reinforcing ribs arranged alternately with the openings on at least one side surface; each opening on one side surface of the drive disc body, along the rotation direction of the drive disc body, has a first groove portion connecting to the opening at the side edge position of its own radial center line; the clutch drive disc of this application has the functions of weight reduction, ventilation and deformation resistance, and can better meet the requirements of high performance and economic performance of dual-clutch systems.

[0004] The aforementioned clutch drive disc, as described in this application, has the functions of weight reduction, ventilation, and deformation resistance, and can better meet the requirements of high performance and economic performance of dual-clutch systems. However, when the drive disc is in use, its weight and volume are relatively large, making transportation and storage of the drive disc quite difficult. Utility Model Content

[0005] The purpose of this invention is to provide a clutch drive disc to solve the problem of existing clutch drive discs being difficult to disassemble and assemble.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a clutch drive disc, including a second drive disc;

[0007] The top of the second drive disk is provided with a first drive disk, and the top of the first drive disk is equipped with an installation ring, the inside of which is provided with a circular hole;

[0008] A positioning ring is engaged on the outer side of the mounting ring, and through holes are provided at the top of both the first drive disk and the second drive disk. A disassembly and assembly structure is installed at the top of the positioning ring.

[0009] The disassembly and assembly structure includes a groove at the bottom of the second drive disc, a screw head inside the groove, a threaded rod at the top of the screw head, and a nut at the top of the threaded rod.

[0010] In use, the wear-resistant layer and the heat insulation layer are firstly applied to the surface of the first drive disk and the second drive disk, which can enhance the wear resistance of the drive disk. Multiple drive disks can be fixed through the disassembly and assembly structure, allowing the drive disks to be disassembled and assembled as needed. The hollowing-out design reduces the weight of the drive disk. The first connecting rod and the second connecting rod can strengthen the hollowing-out design and prevent the structural strength of the drive disk from being reduced due to the hollowing-out design.

[0011] Furthermore, the first and second drive disks are equipped with a weight-reducing structure. Both the first and second drive disks have hollowed-out sections, and a first connecting rod is installed inside the hollowed-out sections. The weight-reducing structure can reduce the weight of the drive disks.

[0012] Furthermore, a second connecting rod is installed inside the hollowed-out area. The second connecting rod intersects with the first connecting rod, and the first and second connecting rods can enhance the structural strength of the hollowed-out area.

[0013] Furthermore, both the first drive disk and the second drive disk are provided with wear-resistant structures on their outer sides. The wear-resistant structures include heat insulation layers on the outer sides of both the first drive disk and the second drive disk, and wear-resistant layers on the outer sides of the heat insulation layers. The surface of the wear-resistant layers is coated with a wear-resistant coating. The wear-resistant structures can enhance the wear resistance of the drive disks.

[0014] Furthermore, the through holes are arranged at equal intervals at the top ends of the first and second drive disks, and the through holes are distributed in a ring shape, which can reduce the material of the drive disks.

[0015] Furthermore, the outer side wall of the threaded rod is uniformly provided with external threads, and the inner side wall of the nut is uniformly provided with internal threads that cooperate with the external threads. The threaded rod and the nut are threadedly connected, and the threaded rod and the nut can fix the first drive disk and the second drive disk together.

[0016] Furthermore, the nuts are arranged in a ring, with equal spacing at the top of the positioning ring, and can be screwed onto the threaded rod.

[0017] The advantages of the clutch drive disc provided by this utility model are: during use, multiple drive discs can be fixed by the disassembly and assembly structure, allowing the drive discs to be disassembled and assembled when needed; the weight of the drive discs can be reduced by the hollowing out of the weight-reducing structure; and the wear resistance of the drive disc surface can be enhanced by the wear-resistant structure.

[0018] By forming a locking structure between the first and second drive discs, the first drive disc can lock the top of the second drive disc, allowing the screw head to be inserted into the groove. Then, the threaded rod can be passed through the first and second drive discs, and the threaded rod and nut form a threaded connection, locking the positioning ring onto the mounting ring. After tightening the nut, the first drive disc, the second drive disc, and the positioning ring can be fixed together. When it is necessary to disassemble the drive disc, the nut can be unscrewed, and then the threaded rod can be pulled out. Then, the first drive disc, the second drive disc, and the positioning ring can be disassembled, which facilitates disassembly and transportation, thereby achieving the purpose of easy disassembly and assembly of the clutch drive disc.

[0019] By creating hollows inside both the first and second drive discs, with the hollows arranged at equal intervals, the large area of ​​hollows can reduce the material and weight of the first and second drive discs. The first and second connecting rods intersect each other, supporting the hollows and strengthening their rigidity. This prevents the hollows from reducing the structural strength of the drive discs, thereby achieving the goal of reducing the weight of the clutch drive disc. Attached Figure Description
