Abstract
The utility model relates to a flywheel with vibration damping effect, which includes a flywheel main body, an inertia ring and a deformable connecting structure, wherein an annular groove is arranged on the flywheel main body and circumferentially extends along the flywheel main body; the inertia ring is sleeved in the annular groove and connected with the annular groove through the deformable connecting structure; and the outer diameter of the inertia ring is smaller than that of the annular groove. The utility model provides the flywheel with vibration damping effect, and solves the problem that the existing flywheel doesn't have the vibration damping effect.
Description
Technical field
The utility model relates to flywheel, relates in particular to a kind of flywheel with damping effect.
Background technique
Because the acting of each cylinder of motor is discontinuous, so engine speed also changes.In order to reduce the speed fluctuation of engine operation process, accomplish through the design flywheel usually.The principle that reduces the speed fluctuation in the engine operation process through flywheel is that when engine speed increased, the kinetic energy of flywheel increased, and stores up energy; When engine speed reduced, flywheel energy reduced, and discharges energy.
When but power train was transmitted engine torque, because internal combustion engine is unbalanced, torque periodically variation can cause the power train torsional vibration.The resonance if power train twists, with the stress that makes Parts for Power Train increase at double, and this stress has destruction, and descended the fatigue life of Parts for Power Train greatly.Torsional vibration still causes the essential condition of gear noiose.Therefore flywheel also needs and can the vibrations that bent axle is passed to it be discharged, to guarantee the normal operation of whole drive unit.Existing flywheel is many to be improved from the gear ring that is installed on the flywheel, however problems such as such improvement causes wearing no resistance easily, poor reliability, rate of fault height.
At Chinese patent number is ZL2009201537757; Name is called in the patent documentation of " shock-decreasing type Automobile flywheel " and discloses a kind of flywheel with shock-absorbing function; This flywheel comprises the flywheel disk body, is arranged on clutch installation screw hole and crank shaft bolt mounting hole on the flywheel disk body; Wherein clutch is installed screw hole and crank shaft bolt mounting hole site in concentric but on two circumference that radius is different; Between two circumference, be provided with damping ring, damping ring is a rubber parts, between flywheel disk body and clutch, realizes damping through damping ring is separated in the using process.
Though this patent has overcome the deficiency that above-mentioned change gear ring is brought, flywheel itself does not possess damping effect.
Summary of the invention
The utility model provides a kind of flywheel with damping effect, has solved the problem that existing flywheel does not have damping effect.
Above technical problem solves through following technical proposal: a kind of flywheel with damping effect; Comprise the flywheel main body, also comprise inertia ring and deformable linkage structure, said flywheel main body is provided with circular groove; Said circular groove is along the extending circumferentially of said flywheel main body; Said inertia ring is set in the said circular groove, and said inertia ring is connected with said circular groove through said deformable linkage structure, and the external diameter of said inertia ring is less than the external diameter of said circular groove." deformable linkage structure " is meant the fastening that the barycenter that in rotation process, can adapt to inertia ring moves and be out of shape thereupon.In the flywheel rotation process, inertia ring with can cash linkage structure and constitute one and turn round the shake device, play the effect that reduces to turn round shake, thereby make flywheel have damping effect.
As preferably; Be stamped cover plate on the said circular groove; Said deformable linkage structure is for filling the silicone oil in the gap between full said inertia ring, circular groove and the cover plate three, and the thickness of said inertia ring is less than the distance between the internal surface of the diapire of said circular groove and said cover plate.As the deformable linkage structure that inertia ring is linked together with the flywheel main body, the degrees of freedom when inertia ring moves is good with the structural type of filled with silicone oil; The meaning of " thickness of inertia ring is less than the distance between the internal surface of the diapire of said circular groove and said cover plate " is meant that the diapire of circular groove and the internal surface of cover plate can not hinder the meaning that inertia ring moves in by circular groove and the two space that surrounds of cover plate.
Preferred as another, said deformable linkage structure comprises rubber ring, and said rubber ring is between the inwall of said inertia ring and said circular groove.Inertia ring is supported as the deformable linkage structure with rubber ring, the elastic damping characteristic is good.
As preferably; The inner ring of said rubber ring is provided with metal ring, and said metal ring is set on the madial wall of said circular groove, and said rubber ring is fixed together with said inertia ring; Said rubber ring is fixed together with said metal ring, and said metal ring is fixed together with said circular groove.Can be easily be fixed in the circular groove rubber ring and inertia ring and convenient when changing.
As preferably, said circular groove is with said flywheel main body coaxial line.The position radius of deformable structure is identical, circumferentially the high conformity of damping effect.
The utlity model has following advantage; Through in the flywheel main body, inertia ring being set, and inertia ring is connected with the flywheel main body through deformable structure, and inertia ring and deformable structure constitute one and turn round the shake device; Play cushioning effect, thereby make flywheel have damping effect.
Description of drawings
Fig. 1 is the utility model embodiment one a schematic representation.
Fig. 2 is the utility model embodiment two a schematic representation.
Among the figure: flywheel main body 1, circular groove 11, inertia ring 2, deformable linkage structure 3, metal ring 31, cover plate 4, gap 5.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Embodiment one, referring to Fig. 1, a kind of have damping turn round the shake effect flywheel, comprise flywheel main body 1, inertia ring 2 and deformable linkage structure 3.
On flywheel main body 1, be provided with circular groove 11, circular groove 11 is along the extending circumferentially of flywheel main body 1.Circular groove 11 is with flywheel main body 1 coaxial line.
Be through realizing metal ring 31 affixed with circular groove 11 with being designed to friction tight mode between the madial wall of metal ring 31 with circular groove in the present embodiment, it also is the same carrying out affixed effect through bolt certainly.
In the using process, when producing vibration, inertia ring 2 and deformable structure 3 play the effect of damping.
Embodiment two, referring to Fig. 2, with embodiment one difference are: on circular groove, be stamped cover plate 4.Cover plate 4 through bolton on flywheel main body 1.The thickness of inertia ring 2 is less than the distance between the internal surface of circular groove diapire and cover plate 4.The thickness direction of inertia ring 2 is axially identical with flywheel main body 1.Deformable linkage structure 3 is for filling the silicone oil in the gap between full inertia ring 2, circular groove and cover plate 4 threes.
