Description
Background technology
The damper of car transmissions has two important functions in the use of car transmissions：Good subtracts
Effect of shaking and enough torque transmission capacities.Transmission system reaches the noise and vibration for reducing automobile engine by torsion vibration absorber
Effect, the moment of torsion of engine passes to gearbox by torsion vibration absorber simultaneously.In actual application, lower rigidity has
Preferably effectiveness in vibration suppression, will obtain lower rigidity it is necessary to design bigger windup-degree；But common damper is because adopting
Use straight-line helix spring damping, straight-line helix spring is limited by the design structure of damper, windup-degree cannot be big again, institute
Can not be little again with rigidity.
Content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the invention provides a kind of can meet Low rigidity with high pulling torque simultaneously
Require damper so that the circular arc spring damper that car transmissions high pulling torque is taken into account with both Low rigidity.
To achieve these goals, the technical solution used in the present invention is：
A kind of circular arc spring damper, including driving disc spacing pressing, and the flange that is fixed on driving disc spacing pressing and cover plate, the driving disc spacing pressing with
At least one arc spring is provided between cover plate, and the arc spring is arranged on the inside of the edge of the driving disc spacing pressing, the arc
The two ends of shape spring are connected with the flange.
Used as the improvement further of such scheme, the arc spring is included outside inner spring, and the sheathed inner spring
Outer spring.
As the improvement further of such scheme, between the driving disc spacing pressing and cover plate, chute is provided with, the arc spring
It is arranged in the chute.
As the improvement further of such scheme, between the arc spring and chute, lubricant grease is provided with.
As the improvement further of such scheme, be also disposed between the flange and cover plate diaphragm spring with driven
Disk, the flange, diaphragm spring, clutch plate and driving disc spacing pressing pass through rivet, and the cover plate is welded with driving disc spacing pressing.
Used as the improvement further of such scheme, the flange is connected with diaphragm spring assembling by support ring and pad
Connect.
Beneficial effects of the present invention：
A kind of circular arc spring damper of the present invention, is provided with arc spring, the power of driving disc spacing pressing in driving disc spacing pressing and the chute of cover plate
Arc spring is passed to, arc spring imparts power to flange, flange imparts power to clutch plate；When arc spring is being slided
When compression is reversed in groove, it is possible to obtain than the twice windup-degree of common damper, while what moment of torsion can be equally is big, so as to
Obtain the torsional rigidity for only having common damper half, there is provided a kind of damping that can meet Low rigidity and high pulling torque requirement simultaneously
Device so that car transmissions high pulling torque is taken into account with both Low rigidity, so as to solve a NVH difficult problem for car transmissions；Arc
Spring includes inner spring and the outer spring outside the sheathed inner spring, improves the torsional strength of arc spring, extends damping
The service life of device.
