The problem of.
The invention is realized by the following technical scheme.
A kind of double mass flywheel, the first mass fraction including the driving torque for starting and transmitting engine and is used for
The second mass fraction of the rotary inertia of speed changer is improved, spring is set in first mass fraction and the second mass fraction
Fixed ring is additionally provided with plane scroll spring, the planar vortex between first mass fraction and the second mass fraction
One end of rotation spring is fixedly connected with the first mass fraction, and the other end and the spring fixed ring of the plane scroll spring are fixed
Connection, also sets up pressing plate between the plane scroll spring and the second mass fraction.The flywheel structure of script is changed, now
The flywheel of new construction be detachably connected, volute spring is simple to manufacture, and used device is at low cost, and pressing plate guarantees axially position, is subtracted
It is small 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 done in slot
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
A kind of double mass flywheel, the first mass fraction 1 and use including the driving torque for starting and transmitting engine
It is set in the second mass fraction 2 of the rotary inertia for improving speed changer, first mass fraction 1 and the second mass fraction 2
Spring fixed ring 5 is set, is additionally provided with plane scroll spring 3, institute between first mass fraction 1 and the second mass fraction 2
The one end for the plane scroll spring 3 stated is fixedly connected with the first mass fraction 1, the other end of the plane scroll spring 3 with
Spring fixed ring 5 is fixedly connected, and pressing plate 4 is also set up between the plane scroll spring 3 and the second mass fraction 2, described
It is provided with the first card slot on first mass fraction 1, the second card slot, the plane are provided in the spring fixed ring 5
The both ends of volute spring 3 are individually positioned in the first card slot and the second card slot, first card slot and the first mass fraction 1
Axis is in 45 degree, and 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
It is fixedly connected with the first mass fraction 1, the clamp surface has coating, and the spring fixed ring 5 passes through the second screw 7
It is fixedly connected with the second mass fraction 2, second screw 7 is sunk screw, and the outer ring of second mass fraction 2 has
There is a slot, the nut portion of the screw does circumferential slippage in slot, positioning is arranged on the right of second mass fraction 2
Gear ring 10 is arranged in pin 6, 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,
