A kind of secondary flywheel air-balance fixture with self-centering apparatus
Technical field
The present invention relates to flywheel positioning clamping field, specially a kind of secondary flywheel with self-centering apparatus is pneumatically put down
Weigh fixture.
Background technique
The twisting vibration that power train is caused to reduce the lack of uniformity of engine rotation, is traditionally adopted in clutch
Reach vibration damping purpose with torsional vibration damper.But on the one hand, which can not method consolidating entire power-transmission system
There is frequency to be reduced to engine idling hereinafter, therefore remaining covibration in entire engine operation process;It is another
Aspect is difficult to pass through reduction in actual design due to being limited and transmitting torque needs by torsional vibration damper spring installation radius
Spring rate reduces torsional oscillation, therefore between the practical range of speeds of engine (1000-2000r/min), it is difficult to pass through reduction
Damper spring stiffness obtains bigger effectiveness in vibration suppression, and in automobile history the double mass flywheel of first batch production is before 1985
It goes into operation afterwards and (is used for BMW car), the secondary mass of double mass flywheel and the separation of speed changer and combination are by one without damper
Positive clutch disk complete, since clutch is without vibration damper mechanism, quality is obviously reduced.Damper is assembled in double matter
It measures in fly wheel system, and can be slided in disk, hence it is evident that improve synchronism and be easy gear shift.
And quality is divided into two by double mass flywheel, the second mass (secondary mass) therein can not increase the used of flywheel
Property square under the premise of improve the moment of inertia of power train, and resonance speed is made to drop to idling speed or less.That is any
In the case of, there is resonance speed all other than the range of speeds of engine operation, but the device is also deposited in processing or context of detection
In some drawbacks: there are no a kind of relatively simple stationary fixtures effectively it to be fixed at present, because one
It needs to carry out effective fixed clamp to it in a little repairings, in common garage, there is no the fixed precisions of expensive genuine
Instrument;Clamping can only be fixed to the flywheel of certain certain fixing model in existing clamping fixture, do not adapt to flying for different model
Wheel;It is manually not accurate enough to the positioning at flywheel center and relatively slow in speed, it is also comparatively laborious in step.
