Description
Technical field
This utility model relates to vehicle transmission field, specifically one to be had and stablizes delayed knot
The double mass flywheel of structure.
Background technology
For elastomer, when applying external force, elastomer can deform, bullet when cancelling external force
Gonosome can come back to original shape, but if applies power more than elastomer stress marginal value
Time, elastomer can not return to original shape and be always maintained at the state of deformation, and deform
Degree is also different because suffered external force varies in size, and also has ferromagnetic as ferrum, when it
If putting into magnetic field magnetization, also retaining magnetic after leaving magnetic field, this magnetic is also because of described magnetic
Magnetic varies in size and different, and above-mentioned phenomenon is hysteresis, wherein in ferromagnetic
The hysteresis occurred is generally termed hysteresis.
Double mass flywheel is applied on the variator of vehicle, is mainly used in absorbing and removing starting
The noise and vibration produced because of rotary speed difference between machine and change speed gear box, double mass flywheel mainly wraps
Including one-level flywheel, two grades of structures such as flywheel, spring coil, one-level flywheel passes through spring when rotating
Coil promotes two grades of flywheels to rotate, and in order to prevent spring coil from departing from, one-level flywheel is provided with one
Level flywheel lid.As shown in figs. 34, the lag structure on usual double mass flywheel is to utilize to cry
The flat spring of barrier film contacts with the one-level flywheel lid of one-level flywheel, utilizes the stress of flat spring anti-
Only realize hysteresis characteristic while oils and fats leakage of oil, but this structure to be barrier film straight with one-level flywheel lid
Contact, contact area is relatively big, easily produces abrasion, persistently maintains hysteresis characteristic relatively difficult.
Utility model content
The purpose of this utility model is to provide a kind of double quality with stable lag structure to fly
Wheel, sets up a packing ring, it is to avoid metal directly contacts between one-level flywheel lid and barrier film, anti-
Only can persistently maintain hysteresis characteristic while oils and fats leakage of oil.
The purpose of this utility model is achieved through the following technical solutions:
A kind of double mass flywheel with stable lag structure, one-level flywheel is provided with one-level flywheel
Lid and barrier film, be provided with packing ring, described one-level flywheel lid between described one-level flywheel lid and barrier film
Edge is provided with the seam portion for installing described packing ring, and described packing ring is propped up by described barrier film.
Described barrier film is provided with lobe, and described packing ring is arranged at described one-level flywheel lid edge
Prop up in seam portion and by the lobe of described barrier film.
Described packing ring is flat shape.
Described packing ring side is provided with hook-shaped.
Described hook-shaped includes bending part and end hook portion, the rectangular bending of described bending part and with
End hook portion is connected to the hanging the edge in described seam portion.
Advantage of the present utility model with good effect is:
1, this utility model arranges packing ring between one-level flywheel lid and barrier film, it is to avoid one-level flies
Directly contacting between wheel cap with barrier film, prevents both because of the abrasion of contact, the most persistently maintains
Hysteresis characteristic.
2, this utility model is arranged between one-level flywheel lid and barrier film packing ring also constitutes sealing
Structure, has the effect preventing oils and fats leakage of oil.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Fig. 1～5, this utility model includes one-level flywheel lid 1, barrier film 2 and packing ring 3,
One-level flywheel lid 1 is arranged on one-level flywheel, and barrier film 2 is arranged in one-level flywheel, described
Being provided with packing ring 3 between one-level flywheel lid 1 and barrier film 2, described one-level flywheel lid 1 edge is provided with
For installing the seam portion 11 of described packing ring 3.
As shown in figs. 34, the side that described barrier film 2 and described packing ring 3 offset is provided with projection
Portion 21, described lobe 21 offsets with described packing ring 3, and this is to prevent barrier film 2 and pad
Circle 3 causes abrasion because too much contacting, and is beneficial to realize stable hysteresis characteristic.
As it is shown on figure 3, inside the seam portion 11 and barrier film 2 at one-level flywheel lid 1 edge
Between lobe 21, packing ring 3 is set, so can avoid intermetallic contact, thus anti-
Only wearing and tearing and realize stable hysteresis characteristic, described packing ring 3 is flat shape and by plastics material
Matter is made, and described packing ring 3 is arranged in the seam portion 11 at described one-level flywheel lid 1 edge,
And propped up by the lobe 21 of barrier film 2, thus form sealing structure and prevent oils and fats leakage of oil.
As shown in Figure 4, in order to ensure the seam portion 11 of packing ring 3 and one-level flywheel lid 1 edge
Fixing more closely, described packing ring 3 side can be bent into hook-shaped, described hook-shaped
Including bending part 32 and end hook portion 31, the described rectangular bending of bending part 32 and with end hook portion
31 are connected to the hanging the edge in described seam portion 11.
As it is shown in figure 5, in the present embodiment, the most uniform at one-level flywheel lid 1 edge
There are four seam portions 11.
Operation principle of the present utility model is:
The packing ring 3 that this utility model is arranged between one-level flywheel lid 1 and barrier film 2, described pad
Circle 3 be arranged in the seam portion 11 of one-level flywheel lid 1 and with the lobe 21 of described barrier film 2
Offset, on the one hand avoid directly contacting between one-level flywheel lid 1 and barrier film 2, prevent both
Because of the abrasion of contact, persistently maintain hysteresis characteristic, simultaneously constitute sealing structure, have and prevent oil
The effect of fat leakage of oil.
