Description

Novel steel wire rope ring dual-mass flywheel

Technical Field

The utility model belongs to the automotive transmission power assembly field, in particular to novel wire rope encircles dual mass flywheel.

Background

At present, a dual-mass flywheel is widely applied to reducing the torsional vibration between transmission systems of automobiles, mainly used for reducing the imbalance of the rotation of an engine. The vibration reduction under the idle working condition can be realized, and the NVH performance of the whole vehicle is improved. The problem of vibration during the ignition phase of an engine is receiving further attention due to the trend toward lighter engines and the need for frequent spark-overs in the engine. However, the existing dual-mass flywheel cannot realize the shock absorption of the automobile under multiple working conditions, particularly the shock absorption in the ignition stage of the engine.

However, the general dual-mass flywheel uses the arc spring as the elastic damping element, and the compression deformation of the arc spring in the spring chamber is used for buffering the irregular torsional vibration in the transmission system, but the circular motion of the arc spring inevitably rubs with the spring chamber, so that the service life of the arc spring is reduced, and the use of lubricating grease and the manufacture of the sealed spring chamber greatly improve the manufacturing cost of the dual-mass flywheel.

Therefore, a new type of wire rope ring dual mass flywheel is needed.

When the input torque of the elastic damping element of the steel wire rope ring is large, namely the excitation amplitude is large enough, internal friction occurs between the steel wire rope strands, the friction force is opposite to the relative speed between the steel wire rope strands, and therefore vibration energy is consumed. But the input torque is smaller, namely, at a small amplitude, the strands of the steel wire rope are twisted together by friction force, and slippage does not occur, so that the linear characteristic of the transmission system is kept. The characteristic enables the wire rope ring dual-mass flywheel to have the capability of enabling a transmission system to avoid strong resonance, and can meet the requirements of a power system of various working conditions from engine ignition to normal running on the vibration resistance and vibration isolation capability of the vehicle.
