Topic.
(2) technical scheme
For realizing object above, this utility model is achieved by the following technical programs: one kind is for double clutch certainly
The flywheel assembly of dynamic variator, including flywheel, the outer ring of described flywheel is arranged with starting gear ring, the inner ring of described flywheel
On be bolted to connection flexible disk, described flexible disk be " y " shape structure, and each branch of " y " shape structure on be welded with
The clamp nut being adapted with bolt, the center of described flexible disk is provided with splined hub, and described splined hub center is provided with spline
Hole.
Preferably, described " y " each branch of shape structure is equipped with two clamp nuts.
Preferably, the quantity of described bolt is no less than six, and bolt is located in flexible disk with two for one group of cincture.
Preferably, in described flexible disk, cincture is provided with loss of weight fabrication hole.
(3) beneficial effect
This utility model provides a kind of flywheel assembly for double-clutch automatic gearbox.Possess following beneficial
Effect:
(1), this is used for the flywheel assembly of double-clutch automatic gearbox, increases " y " shape compliant mechanism on flywheel,
Make it have power transmission steadily, shock resistance shock-absorbing capacity is high, torsional moment is big, lightweight the features such as, reduce electromotor and be delivered to
The shock loading of clutch and axial vibration；The function of flywheel makes it have certain rotary inertia again, electromotor is done work and rushes
A part for energy produced by journey is stored up, in order to overcome the resistance of other auxiliary strokes, so that engine idle is steadily,
And improve the ability that electromotor overcomes short-term over loading, so that vehicle is easily started to walk.
(2), this is used for the flywheel assembly of double-clutch automatic gearbox, and structure is simple, and processing technology is good, manufactures

Brief description
Fig. 1 is this utility model structural representation；
Fig. 2 is the side sectional view of this utility model structure；
In figure, 1 flywheel, 2 starting gear rings, 3 bolts, 4 flexible disk, 41 loss of weight fabrication holes, 5 clamp nuts, 6 splined hub, 7 flowers
Keyhole.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
This utility model embodiment provides a kind of flywheel assembly for double-clutch automatic gearbox, such as Fig. 1-2
Shown, including flywheel 1, flywheel 1 adopts cast iron materials to make, and the outer ring of flywheel 1 is arranged with starting gear ring 2, the inner ring of flywheel 1
Above flexible disk 4 is fixedly connected with by bolt 3, flexible disk 4 is welded with the clamp nut 5 being adapted with bolt 3, bolt 3
Quantity is no less than six, and bolt 3 is located in flexible disk 4 with two for one group of cincture, and cincture in flexible disk 4 is provided with loss of weight technique
Hole 41, flexible disk 4 is " y " shape structure, and this structural strength is high, lightweight, and is equipped with two clamp nuts 5 on each branch,
Fixation.The center of flexible disk 4 is provided with splined hub 6, and splined hub 6 center is provided with splined hole 7.
Operation principle: during work, flywheel 1 is arranged on the flange of engine crankshaft tail end, flexible disk 4 passes through splined hole 7
With the input shaft interference fit of double clutch, it is reliable that such design ensures that flywheel 1 assembly is connected with double clutch, and electromotor is turned round
