Description

Technical Field

[0001] The utility model relates to the technical field of clutches, in particular to a clutch plate for reducing vibration and noise. Background Art

[0002] In the power transmission system, the clutch is an important component that connects the engine and the transmission, allowing the driver to control the vehicle's power transmission. The performance of the clutch not only affects the vehicle's power transmission efficiency, but also affects the ride comfort. However, traditional clutch plates are prone to vibration and noise when operating at high speeds, which can have an adverse effect on the driving experience and vehicle performance.

[0003] The patent with publication number CN218718314U discloses a low-noise clutch friction plate, including a pressure plate and a friction plate body. A plurality of the friction plate bodies are fixedly mounted on the pressure plate, and each of the friction plate bodies is provided with a noise reduction portion capable of reducing noise. The low-noise clutch friction plate, through the noise reduction portion composed of a connecting layer, a cushion layer and a sound-absorbing layer, can make the sound waves generated by the friction vibration of the friction plate be absorbed by the sound-absorbing layer, and some of the unabsorbed sound waves will pass through the sound-absorbing layer and then be reflected by the concave-convex structure inside the connecting layer, and then be reflected again to the sound-absorbing layer for absorption, thereby reducing and absorbing most of the noise. In addition, the rubber filling layer provided on the cushion layer can reduce the overall elastic modulus of the friction plate, improve the vibration attenuation ability of the friction plate, and partially suppress the front-end vibration of the noise, so the noise reduction portion can further reduce the generation and propagation of noise.

[0004] Although the above-mentioned prior art can achieve the effect of noise reduction, the rigid friction surface will vibrate when friction occurs. If the vibration is not reduced in time, it will accelerate the wear of the clutch plate and related transmission parts and shorten their service life. The vibration may also generate or aggravate noise problems, which not only affects the driving experience. In view of this, we propose a clutch plate with vibration reduction and noise reduction.
