Dual mass flywheel

Abstract

The invention relates to a dual mass flywheel. The dual mass flywheel comprises a first mass flywheel and a second mass flywheel, wherein the first mass flywheel is connected with a driving shaft through a bearing, the other end of the driving shaft is connected with the second mass flywheel through a bearing, the first mass flywheel is fixed with the second mass flywheel through a honeycomb-shaped rubber disc, the honeycomb-shaped rubber disc is connected with the first mass flywheel and the second mass flywheel through elastic connectors respectively, and the honeycomb-shaped rubber disc isprovided with compact honeycomb holes. The dual mass flywheel has the advantages that the structure is simple, the damping effect is good, the dual mass flywheel is resistant to wear, the service lifeis long, the practicability is high, and the use is convenient.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a dual-mass flywheel. Background technique [0002] Dual-mass flywheel is usually used as a shock absorber in the process of power transmission of automobiles to reduce the torsional vibration of the output shaft of the engine, so that the automobile has better NVH performance. The dual-mass flywheel is generally arranged between the engine and the gearbox, and the output shaft of the engine is fixedly connected to one of the flywheels to drive the flywheel to rotate; the other mass flywheel is adapted to be fixed with the input shaft of the gearbox to transmit power to In the prior art, the two quality flywheels are connected through various types of springs, and the relative rotation between the two flywheels is used to eliminate torsional vibrations, but no matter what type of spring, the same as the double The contact area of ​​the mass flywheel is limited, th...

Problems solved by technology

The dual-mass flywheel is generally arranged between the engine and the gearbox, and the output shaft of the engine is fixedly connected to one of the flywheels to drive the flywheel to rotate; the other mass flywheel is adapted to be fixed with the input shaft of the gearbox to transmit power to In the prior art, the two quality flywheels are connected through various types of springs, and the relative rotation between the two flywheels is used to eliminate torsional vibrations, but no matter what type of spring, the same as the double The contact area of ​​the mass flywheel is limited, the damping effect cannot be the best, and the service life of the spring is limited. After a long period of use, the elastic effect will be reduced, affecting the use effect, and the practicability is not strong. The prior art Most of the connections of the dual-mass flywheel are rigid connections, which cannot achieve a good shock absorption effect and are very inconvenient to use. Therefore, it is necessary to provide a simple structure, good shock absorption effect, wear resistance, long service life, strong practicability and A convenient dual-mass flywheel is necessary
