Description

Technical Field

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

[0002] The clutch is an important component in the automobile transmission system. Its main function is to connect and disconnect the power transmission between the engine and the transmission. The clutch driven plate is a key component in the clutch assembly. It plays an important role in the clutch system. The driven plate is located between the clutch pressure plate and the flywheel. Its main function is to transfer the engine power to the transmission through friction.

[0003] When the existing clutch driven plate is in use, four damping springs are provided to reduce vibration of the driven plate. Therefore, when the shaft body is inserted into the spline, the flower plate will first rotate to drive the main plate to rotate using the bearing, and use multiple damping springs to reduce vibration, thereby avoiding the impact force during sudden rotation from causing damage to the clutch. However, the damping springs are generally provided in a square opening, and the flower plate applies pressure to the multiple damping springs by circular rotation. The pressure direction is inclined to one end of the spring, and the contraction of the damping spring is generally performed by horizontal movement inside the square opening. The force direction of the spring is inconsistent with the sliding damping direction. After multiple operations, the oblique pressure of the flower plate can easily cause damage to the spring, thereby reducing the damping effect and shortening the service life of the clutch.

[0004] Therefore, it is necessary to design a clutch driven disc vibration reduction structure to solve the above problems. Utility Model Content
