In arc spring installation accuracy require high, difficult to install, the more rivet interlacements disassemblies of stamping parts are difficult, all scrap once damaging
The problem of.
The utility model is achieved through the following technical solutions.
Double mass flywheel, the first mass fraction including the driving torque for starting and transmitting engine and for improving
Setting spring is fixed in second mass fraction of the rotary inertia of speed changer, first mass fraction and the second mass fraction
Ring is additionally provided with plane scroll spring, the plane vortex bullet between first mass fraction and the second mass fraction
One end of spring is fixedly connected with the first mass fraction, and the other end and spring fixed ring of the plane scroll spring are fixed to be connected
It connects, also sets up pressing plate between the plane scroll spring and the second mass fraction.The flywheel structure of script is changed, present
The flywheel of new construction is detachably connected, and volute spring is simple to manufacture, and used device is at low cost, and pressing plate guarantees axially position, is reduced
It is circumferential mobile.
Preferably, being provided with the first card slot on first mass fraction, it is provided in the spring fixed ring
Second card slot, the both ends of the plane scroll spring are individually positioned in the first card slot and the second card slot.Volute spring is fixed
Securely.
Preferably, the axis of first card slot and the first mass fraction is in 45 degree, first card slot and the
The axis of one mass fraction is in 45 degree.Facilitate the both ends of volute spring to be put into, increases reliability.
Preferably, the pressing plate is fixedly connected by the first screw with the first mass fraction.Convenient disassembly.
Preferably, the clamp surface has coating.Smooth plating layer reduces coefficient of friction.
Preferably, the spring fixed ring is fixedly connected by the second screw with the second mass fraction.
Preferably, second screw is sunk screw.Sunk screw saves space
Preferably, the outer ring of second mass fraction has a slot, the nut portion of the screw is in slot
Inside do circumferential slippage.
Preferably, shop bolt is arranged on the right of second mass fraction.For determining for the parts such as back clutch
Position.
Preferably, gear ring is arranged outside first mass fraction.
Compared with prior art: reducing cost, mitigate installation difficulty, the multiple arcs spring of script is replaced with monoblock type
Plane turbine spring, be convenient for changing and Awaiting Parts.

Specific embodiment
Double mass flywheel, the first mass fraction 1 including the driving torque for starting and transmitting engine and for mentioning
Bullet is set in second mass fraction 2 of the rotary inertia of high speed changer, first mass fraction 1 and the second mass fraction 2
Spring fixed ring 5 is additionally provided with plane scroll spring 3 between first mass fraction 1 and the second mass fraction 2, described
One end of plane scroll spring 3 is fixedly connected with the first mass fraction 1, the other end and spring of the plane scroll spring 3
Fixed ring 5 is fixedly connected, and also sets up pressing plate 4 between the plane scroll spring 3 and the second mass fraction 2, and described first
It is provided with the first card slot on mass fraction 1, the second card slot, the plane vortex are provided in the spring fixed ring 5
The both ends of spring 3 are individually positioned in the first card slot and the second card slot, the axis of first card slot and the first mass fraction 1
In 45 degree, the axis of first card slot and the first mass fraction 1 is in 45 degree, and the pressing plate 4 passes through the first screw 8 and the
One mass fraction 1 is fixedly connected, and the clamp surface has coating, and the spring fixed ring 5 passes through the second screw 7 and the
Two mass fractions 2 are fixedly connected, and second screw 7 is sunk screw, and the outer ring of second mass fraction 2 has one
A slot, the nut portion of the screw do circumferential slippage in slot, shop bolt are arranged on the right of second mass fraction 2
6, gear ring 10 is arranged in first mass fraction 1 outside.
During the installation process, plane scroll spring 3 is put into the annular groove of the first mass fraction 1 first, it is described
One end of plane scroll spring 3 be fixedly connected with the first mass fraction 1, the other end and bullet of the plane scroll spring 3
Spring fixed ring 5 is fixedly connected, and one end of plane scroll spring 3 is embedded in the first card slot, and the other end is embedded in the second card slot,
