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 torque of engine passes to gearbox simultaneously by torsion vibration absorber.In actual application, lower rigidity has
Better effectiveness in vibration suppression will obtain lower rigidity it is necessary to design bigger windup-degree；But common damper is because adopting
With straight-line helix spring damping, straight-line helix spring is limited by the design structure of damper, windup-degree can not be big again, institute
It can not be small again with rigidity.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of Low rigidity and large torques of capable of meeting simultaneously
It is required that damper, so that the circular arc spring damper that both car transmissions large torque and Low rigidity are taken into account.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of circular arc spring damper, including driving disc spacing pressing, and the flange and cover board that are fixed on driving disc spacing pressing, the active
At least one arc spring is provided between disk and cover board, the arc spring is arranged on the inside of the edge of the driving disc spacing pressing, institute
State arc spring both ends and the flanged joint.
As a further improvement of the foregoing solution, the arc spring includes inner spring, and is arranged outside the inner spring
Outer spring.
As a further improvement of the foregoing solution, sliding slot, the arc spring are provided between the driving disc spacing pressing and cover board
It is arranged in the sliding slot.
As a further improvement of the foregoing solution, lubricant grease is provided between the arc spring and sliding slot.
As a further improvement of the foregoing solution, be also disposed between the flange and cover board diaphragm spring with it is driven
Disk, the flange, diaphragm spring and driven disc are welded by rivet, the cover board and driving disc spacing pressing.
As a further improvement of the foregoing solution, the flange is connected by support ring and the assembly of gasket and the diaphragm spring
It connects.
Beneficial effects of the present invention:
It is provided with arc spring in the sliding slot of a kind of circular arc spring damper of the present invention, driving disc spacing pressing and cover board, driving disc spacing pressing
Power passes to arc spring, and arc spring imparts power to flange, and flange imparts power to driven disc；Work as arc spring
When compressing torsion in sliding slot, windup-degree more twice than common damper can be obtained, while that torque can be the same is big,
To obtaining the torsion stiffness for there was only common damper half, provide a kind of can meet Low rigidity and large torque requirement simultaneously
Damper, so that both car transmissions large torque and Low rigidity are taken into account, to solve the NVH problem of car transmissions；
Arc spring includes inner spring and the outer spring that is arranged outside the inner spring, improves the torsional strength of arc spring, extends
The service life of damper.
