Embodiment
In the utility model, damper pulley device embodiment, as shown in Fig. 1 ~ Fig. 7, comprises vibration damping hub 5, belt pulley 8 and flange plate 9.
Wherein the structure of vibration damping hub 5 is as shown in Fig. 5-Fig. 6, comprise the radial flange being arranged on outer circumferential face and be arranged on the inner flange on inner peripheral surface, the spring fenestra 52 that radial flange is provided with groove 51 and embeds for shock-absorbing spring, inner flange is provided with vibration damping hub bolt hole 53.The structure of flange plate 9 is as shown in Fig. 3-Fig. 4, comprise the flange plate bolt hole 91 fixing for the bent axle by bolt and motor and for by bolt and the fixing flange plate tapped hole 92 of vibration damping hub, bolt can be tightened onto on flange plate tapped hole 92 through after vibration damping hub bolt hole 53, and vibration damping hub 5 can be connected with transmission of crankshaft.By flange plate 9 is set, after vibration damping hub 5 can assemble with belt pulley 8, entirety is installed on bent axle by flange plate 9, and processing is convenient in assembling, easy to maintenance.
Spring fenestra 52 in vibration damping hub 5 is provided with six, left side damping disk(-isc) 3 and right side damping disk(-isc) 7 also have six identical damping disk(-isc) spring fenestras 32, but all there is flange in a side of corresponding damping disk(-isc) spring fenestra 32 radial flanges away from vibration damping hub 5 on left side damping disk(-isc) 3 and right side damping disk(-isc) 7, form stopping plate, can keep that spring in each fenestra is unlikely in movement process to be deviate from vertically.In each spring fenestra, two-stage shock-absorbing spring 6 is housed, be connected with right side damping disk(-isc) 7 elasticity in a circumferential direction so as to realizing vibration damping hub 5, the corresponding hole wall of spring fenestra 52 and damping disk(-isc) spring fenestra 32 is formed for the Stop structure coordinating along circumferential block with shock-absorbing spring 6, in the time that vibration damping hub 5 is rotated, compression shock-absorbing spring 6, and be delivered on right side damping disk(-isc) 7 by the damping disk(-isc) spring fenestra 32 on right side damping disk(-isc) 7, drive right side damping disk(-isc) 7 to rotate.
Shock-absorbing spring 6 is provided with two-stage, comprises little rigid spring 61 and is set in the large rigid spring 62 on little rigid spring 61, as the elastic member of the impact between buffer shock-absorbing hub 5 and belt pulley 8.Little rigid spring 61 is as prime shock-absorbing spring, and large rigid spring 62 is as rear class shock-absorbing spring.Little rigid spring 61 and large rigid spring 62 centerings arrange, and the length of little rigid spring 61 is greater than the length of large rigid spring 62, and the [coefficient of of little rigid spring 61 is less than the [coefficient of of large rigid spring 62.Like this, in the time that two-stage shock-absorbing spring is stressed, along with stressed increase, i.e. the increase of transmitting torque, the rigidity of shock-absorbing spring entirety can be changed from small to big.Right side damping disk(-isc) 7 adopts rivet to connect into an entirety by rivet hole 31 with left side damping disk(-isc) 3, and the damping sheet 4 of vibration damping hub 5 and both sides thereof is clipped in the middle, between the both sides cell wall of the respective slot 51 in rivet and vibration damping hub 5, all leave gap, allow to relatively rotate certain angle between right side damping disk(-isc) 7 and vibration damping hub 5.Vibration damping hub 5 is supporting belt pulley 8 by rolling bearing 2, and the inner ring of rolling bearing 2 is set on the outer circumferential face of vibration damping hub 5, and belt pulley 8 is set on the outer ring of rolling bearing 2, thereby can bear the belt pull radially that belt pulley 8 is subject to.Belt pulley 8 is rigidly connected by the belt pulley bolt hole 81 on wheel disc and the damping disk(-isc) tapped hole 71 on right side damping disk(-isc) 7, and the moment of torsion of bent axle can be passed to belt pulley 8 and be driven belt running by right side damping disk(-isc) 7.Diaphragm seal 1 is arranged in vibration damping hub 5, its objective is and prevents that dust and other impurities from affecting the life-span of bearing.Therefore, in the time that the torque ripple of bent axle is delivered to vibration damping hub 5 by flange plate 9, vibration damping hub 5 passes to right side damping disk(-isc) 7 by the vibration-damping function of the two-stage shock-absorbing spring of spring fenestra 52 the insides by moment of torsion, right side damping disk(-isc) 7 is rigidly connected by bolt hole 81 with belt pulley 8, and then the torque ripple after decay is delivered on belt.In this process, right side damping disk(-isc) 7 and left side damping disk(-isc) 3 be with the relative reciprocally swinging between vibration damping hub 5, and the energy that can rely on friction between two damping sheets 4 and above-mentioned three to consume torsional vibration is decayed rapidly Relative Vibration.
When use, first flange plate 9 is installed to by bolt hole 91 on the crankshaft end of motor, and then the damper pulley device assembling is installed on flange plate by the vibration damping hub bolt hole 53 in vibration damping hub 5 and flange plate tapped hole 92 mode with bolts, now damper pulley main body and flange plate have all been installed on the bent axle of motor.Stressed hour when belt, for example on passenger vehicle, air-conditioning is closed, air condition compressor is not while working, and two-stage shock-absorbing spring can pass through little rigid spring 61 carry-over moments of rigidity minimum, and now the decrement of spring is also not enough to be compressed to large rigid spring 62; When belt stressed when larger, for example, when passenger vehicle overhead tunes to open and opens, air condition compressor is worked, little rigid spring 61 is not enough to transmitting large torque, the corresponding sidewall that little rigid spring 61 is continued to be compressed to vibration damping hub 5 and right side damping disk(-isc) 7 upper spring fenestras all can touch large rigid spring 62, transmitting torque under two spring actings in conjunction, the vibration damping output while realizing high pulling torque.By the composite rigidity of Optimal Spring, can realize the best vibration damping output of belt pulley under multiple Operation Conditions, effectively improve bel-drivenn torsional vibration characteristic, reduce the vibration of belt and coupling thereof, promote the travelling comfort of car load.
In the utility model, a kind of vehicle embodiment comprises motor and damper pulley device for being connected with the transmission of crankshaft of motor, the structure of bent axle is same as the prior art, the structure of damper pulley device is identical with the damper pulley device in above-described embodiment, no longer illustrates herein.
In the above-described embodiments, elastic member is two-stage shock-absorbing spring, and in other embodiments of the present utility model, elastic member also can be set to three grades of above shock-absorbing springs; In addition, in above-described embodiment, in vibration damping hub 5, the axial both sides of radial flange are respectively equipped with left side damping disk(-isc) and right side damping disk(-isc), wherein right side damping disk(-isc) and belt pulley 8 are fixing, in other embodiments of the present utility model, left side damping disk(-isc) 3 can also omit or replace to other forms, as long as can realize the moment of torsion transmission between vibration damping hub 5 and belt pulley 8, correspondingly, damping sheet 4 also can arrange a slice accordingly.Moreover the damper pulley device of said structure in use, can select as input component or output member according to different situations by vibration damping hub and flange plate.
