Specific embodiment

In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain The utility model, is not used to limit the utility model.

Refer to Fig. 1, Fig. 2 and Fig. 3, a kind of double mass flywheel 100 that the utility model embodiment is provided, including the first matter Amount flywheel 11, the second mass flywheel 12, ring flange 13 and two spring cushions 20；Ring flange 13 and the phase of the second mass flywheel 12 Connect, two spring cushions 20 are located at the both sides of ring flange 13 respectively, so that the both ends of each spring cushion 20 support respectively The side end face of ring flange 13；Two spring cushions 20 are located at the first mass flywheel 11 and the second mass flywheel 12 with ring flange 13 Between, storage tank 111 is offered on the first mass flywheel 11, each spring cushion 20 is arranged in storage tank 111, so as to bullet Spring shock absorber 20 is positioned, while alloing spring cushion 20 to be slided in storage tank 111.

The spring cushion 20 includes arc spring 21, and the curved setting of arc spring 21 can be easily installed in the In storage tank 111 on one mass flywheel 11.Arc spring 21 has two ends, and two ends are respectively used to support ring flange 13 end faces, each end has end coil 211, and each end is provided with reinforcing mechanisms, and reinforcing mechanisms are somebody's turn to do for 13 Duis by ring flange The active force of arc spring 21 is concentrated towards the line footpath middle part 212 of the corresponding end coil 211 in the end, so as to prevent tag wire Circle 211 is broken.

Reinforcing mechanisms are set by each end of arc spring 21, are flown when the both ends of arc spring 21 support double quality The end face of the ring flange 13 of wheel 100, and operationally, when ring flange 13 produces repeated stock power to arc spring 21, Ke Yitong Cross reinforcing mechanisms to increase the intensity of each end of arc spring 21, and make the active force of ring flange 13 towards the terminal of respective end The line footpath middle part 212 of coil 211 is concentrated, such that it is able to prevent end coil 211 to be broken, it is to avoid produce abnormal sound or damper mechanism to lose Effect.

The double mass flywheel 100 has used above-mentioned spring cushion 20, such that it is able to prevent the arc of spring cushion 20 The end coil 211 of each end of spring 21 is broken, it is to avoid produce abnormal sound or damper mechanism failure.

Further, filled with lubricating oil in storage tank 111, to be lubricated to arc spring 21, arc spring is reduced 21 frictional force being subject to.

Specifically, in the present embodiment, reinforcing mechanisms include being respectively arranged on the closing-in structure 22 of each end of arc spring 21, respectively Closing-in structure 22 includes each end coil 211 of arc spring 21, and the diameter a of end coil 211 is less than the middle part of arc spring 21 Diameter b.Closing-in structure 22 is set, and the diameter a of end coil 211 is less than the mid diameter b of arc spring 21, so as in terminal When coil 211 supports 13 end face of ring flange, the top of ring flange 13 can be to steel with the outside steel wire contact point of end coil 211 The middle part 212 of silk offsets, so that ring flange 13 can be towards the middle part of the steel wire to the active force of the outside steel wire of end coil 211 212 concentrate, and then prevent end coil 211 to be broken, it is to avoid produce abnormal sound or damper mechanism failure.

Further, the diameter a scopes of end coil 211 are to make the corresponding steel wire in outside of the end coil 211 and method The top contact of blue disk 13 is in the middle part 212 and the outside at the middle part 212 of the line footpath of the end coil 211.The structure sets Meter, makes the corresponding steel wire in outside of end coil 211 that the line footpath of the end coil 211 is in the top contact of ring flange 13 Middle part 212 and the outside in the middle part of this, so as to end coil 211 be subject to ring flange 13 repeated stock power when, end can be made The middle part of end-coil 211 or overall stress, so as to preferably prevent end coil 211 to be broken.

Further, the cross section semicircular in shape of the steel wire of each end coil 211.By the steel wire of each end coil 211 Cross section semicircular in shape, can make the steel wire of end coil 211 preferably contact and support the end face of ring flange 13, and then make arc Shape spring 21 can preferably to the transmitting forces of ring flange 13.

In the present embodiment, the diameter a of the end coil 211 of arc spring 21 is only set into the middle part less than arc spring 21 Diameter b.In some other embodiment, each closing-in structure 22 also includes an at least turn coil neighbouring with each end coil 211； And in each coil of close end coil 211：By the medium position of arc spring 21 to end coil 211, the diameter of each coil It is gradually reduced.The structure, after end coil 211 is subject to the active force of ring flange 13, and when being delivered to 21 middle part of arc spring, The stress of each coil of adjacent terminals coil 211 can be made to be increasingly towards in the middle part set of offsets of the steel wire of corresponding coil, so that Can preferably prevent each coil of adjacent terminals coil 211 from fatigue fracture occurring.

In further embodiments, reinforcing mechanisms include the pressing plate being welded on each end.Strengthened using pressing plate function Mechanism, and pressing plate is welded on each end of arc spring 21, can both increase the intensity of each end of arc spring 21, again can be When each end of arc spring 21 is subject to the impulsive force of ring flange 13, by pressing plate come the stress impulsive force, then arc is passed to Spring 21, and then prevent the end coil 211 of arc spring 21 to be broken.Further, the steel wire of each end coil 211 is transversal Face semicircular in shape.In the structure, by the cross section semicircular in shape of the steel wire of each end coil 211, pressing plate can be conveniently welded.

Further, the opposite sides of ring flange 13 is protruding with the gear for supporting the end of each spring cushion 20 respectively Plate.Baffle plate is respectively provided with the opposite sides of ring flange 13, can be preferably each with the arc spring 21 of spring cushion 20 End offsets, and so as to the more preferable transmitting forces of arc spring 21, and then promotes ring flange 13.

Also referring to Fig. 1, the utility model embodiment also discloses a kind of automobile, including double mass flywheel as described above 100.The automobile has used above-mentioned double mass flywheel 100, so that damping efficiency is good, the end coil of its each end of arc spring 21 211 are not susceptible to fracture, better quality.

Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
