Field.
Background technology
Cause the twisting vibration of power train to reduce the lack of uniformity of engine rotation, adopt in clutch traditionally
Vibration damping purpose is reached with torsional vibration damper.But on the one hand, this torsional vibration damper cannot method consolidating whole power-transmission system
There is frequency to be reduced to below engine idle, therefore in whole engine operation process, remain covibration；Another
Aspect is needed owing to limiting and transmitting moment of torsion by torsional vibration damper spring installation radius, is difficult to by reducing in actual design
Spring rate reduces torsional oscillation, therefore between the electromotor practicality range of speeds (1000-2000r/min), it is difficult to by reducing
Damper spring stiffness obtains bigger effectiveness in vibration suppression.
The secondary mass of double mass flywheel separates with variator and combines by a positive clutch without vibroshock
Dish completes, owing to clutch is obviously reduced without vibration damper mechanism, quality.Vibroshock is assembled in double mass flywheel system
In, and can slide in dish, hence it is evident that improve synchronicity and make gear shift easy.

Whether single mass flywheel or double mass flywheel, when it adjusts the torque pulsation of engine output shaft, flywheel pair
The moment of torsion peak value of engine output shaft is pruned ineffective, but for compression oil gas time the lowest point fill out inadequate.Described peak clipping is filled out
Paddy is not to go to fill out paddy by the amount of the peak value pruned, but is moved rearwards by the peak pruned, and fills out paddy not, namely defeated to electromotor
The negative torque of shaft compensates not, and when car starts, due to the inertia of automobile, electromotor will not stop working, but when idling,
Losing automobile inertial, only the rotary inertia of rotatable parts compensates negative torque when compressing oil gas, it is necessary to increase speed ability
