Description

Technical Field

[0001] The utility model relates to the technical field of automobile clutches, in particular to a torsional vibration reduction automobile clutch driven disc assembly. Background Art

[0002] The clutch plate assembly is an important part of the clutch system. Its design and function are crucial to ensure the smooth operation and power transmission of the vehicle's transmission system. The clutch plate assembly consists of a plate body, friction plate, torsional vibration damper, and a plate hub. The plate may adopt a variety of structural forms. In short, the clutch plate assembly is a complex and critical component. Its design, manufacturing, and performance directly affect the driving performance of the vehicle and the stability of the transmission system.

[0003] For example, the Chinese patent "A torsional vibration reduction automobile clutch driven disc assembly" with announcement number CN214063613U includes a driven disc body, the front and rear surfaces of the driven disc body are fixedly connected with friction plates by rivets, the driven disc body is provided with a mounting groove, the inner cavity of the mounting groove is fixedly installed with a vibration reduction spring, the friction plate includes a coating layer, a wear-resistant layer, a first corrosion-resistant layer, a first high-temperature resistant layer, a first high-strength layer and a low-temperature resistant layer, the coating layer is coated on the outer surface of the wear-resistant layer, the wear-resistant layer is located on the outer surface of the first corrosion-resistant layer, the first corrosion-resistant layer is located on the outer surface of the first high-temperature resistant layer, the first high-temperature resistant layer is located on the outer surface of the first high-strength layer, the first high-strength layer is located on the outer surface of the low-temperature resistant layer, the driven disc body includes a second corrosion-resistant layer, a second high-temperature resistant layer, a second high-strength layer and a third high-strength layer, and the second corrosion-resistant layer is located on the outer surface of the second high-temperature resistant layer.

[0004] Although the above-mentioned prior art can realize torsional vibration reduction of the driven plate of automobile clutch, in actual use, on the one hand, it is difficult to buffer the torsional vibration between the vibration reduction plate and the driven plate, and the vibration reduction plate and the driven plate are fixed by bolts, which causes the generated vibration to be directly transmitted to the vibration reduction plate, which can easily cause the vibration reduction plate to collide and be damaged. On the other hand, the driven plate and the vibration reduction plate are prone to mutual friction, and the contact position between the driven plate and the vibration reduction plate is prone to wear when the driven plate is working, thereby shortening the service life of the driven plate assembly. Therefore, it does not meet the existing needs. In this regard, we propose a torsional vibration reduction automobile clutch driven plate assembly. Utility Model Content

[0005] The utility model aims to provide a torsional vibration damping automobile clutch driven plate assembly to solve the problems in the above-mentioned background technology that it is difficult to buffer the torsional vibration between the damping plate and the driven plate, and that the driven plate and the damping plate are easy to rub against each other.

[0006] To achieve the above object, the utility model provides the following technical solution: a torsional vibration damping automobile clutch driven disc assembly, comprising a driven disc, a spline gear hub is fixedly arranged at the middle position of the front end of the driven disc; and further comprising:

[0007] A damping plate, which is arranged at the front end of the driven plate located outside the spline gear hub, the damping plate is provided with four mounting grooves inside, and the mounting grooves are distributed in an annular shape and at equal intervals, a damping spring is arranged inside the mounting groove, and one end of the damping spring is fixedly connected to the inner wall of the mounting groove;

[0008] An extrusion block is arranged at the front end of the driven disk located outside the spline gear hub. Four extrusion blocks are arranged, and the positions of the extrusion blocks correspond to the installation grooves. The other end of the damping spring is fixedly connected to the extrusion block.

[0009] Preferably, the outermost layer of the driven disc is provided with a first wear-resistant layer, and the outermost layer of the damping disc is provided with a second wear-resistant layer.

[0010] Preferably, the surface layer of the driven disc below the first wear-resistant layer is provided with a first corrosion-resistant layer, and the surface layer of the damping disc below the second wear-resistant layer is provided with a second corrosion-resistant layer.

[0011] Preferably, the surface layer of the driven disk located below the first corrosion-resistant layer is provided with a first high-temperature resistant layer, and the surface layer of the damping disk located below the second corrosion-resistant layer is provided with a second high-temperature resistant layer.

[0012] Preferably, the surface layer of the driven disk located below the first high temperature resistant layer is provided with a first polymer layer, and the surface layer of the damping disk located below the second high temperature resistant layer is provided with a second polymer layer.

[0013] Preferably, a positioning groove is provided inside the vibration damping plate between the installation grooves, and the positioning groove is an open structure. A limiting bolt is provided inside the positioning groove, and the limiting bolt is fixedly connected to the driven plate.

[0014] Preferably, a plurality of heat dissipation grooves are arranged inside the front end of the driven plate located outside the limiting bolt, and the heat dissipation grooves are distributed in an annular shape with equal distances.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can absorb the impact and torsional vibration of the damping plate during movement through the extrusion block and the damping spring. When the driven plate is working, the driven plate and the damping plate both rotate. The impact and torsional vibration generated during the rotation of the driven plate will squeeze the damping spring through the extrusion block. At this time, the damping spring is in a compressed state. When the impact and torsional vibration weaken or disappear, the damping spring is reset. The absorbed energy is released through the reset of the damping spring and the damping plate is restored to its original position, thereby avoiding damage to the damping plate and the driven plate caused by the impact and torsional vibration.

[0017] 2. The utility model can protect the surface of the vibration damping plate and the driven plate through the first wear-resistant layer and the second wear-resistant layer. When the driven plate is working, both the driven plate and the vibration damping plate rotate. During the rotation, friction will be generated at the contact part of the vibration damping plate and the driven plate. The first wear-resistant layer and the second wear-resistant layer can improve the wear resistance of the vibration damping plate and the driven plate, thereby extending the service life of the vibration damping plate and the driven plate. A large amount of heat will be generated when the vibration damping plate and the driven plate rub against each other. The second high-temperature resistant layer and the first high-temperature resistant layer can improve the heat resistance of the vibration damping plate and the driven plate, thereby avoiding the high temperature from affecting the performance of the vibration damping plate and the driven plate.

[0018] 3. The utility model can reduce the friction noise between the driven plate and the damping plate through the second polymer layer and the first polymer layer. When the driven plate is working, both the driven plate and the damping plate rotate. During the rotation, friction will be generated at the contact part between the damping plate and the driven plate, resulting in certain noise during the wear process. The lower friction coefficient of the second polymer layer and the first polymer layer can reduce the wear and friction noise between the damping plate and the driven plate.
