Description
Technical field
The invention belongs to technical field of internal combustion engines, more particularly, to a kind of damping vibration combination flywheel.
Background technique
With the development of vehicle, division of labor based on specialization is more and more thinner, the NVH of vehicle (Noise, Vibration,
Harshness, noise, vibration and sound vibration roughness) problem becomes the major vehicle manufacturing enterprise of international automobile industry and components are looked forward to
One of the problem of industry is paid close attention to.Client is also higher and higher for the comfort requirement of driving, and NVH becomes the most direct most table of customer perception
The evaluation criterion in face.MT gearbox is matched using single mass flywheel, single mass flywheel is generally gray iron or cast iron materials
And main part is an integral structure, this material elongation percentage is very low, and the vibration of engine is transmitted to clutch by flywheel, leads to
It is transmitted to gearbox after crossing clutch decaying, however some product gearboxes have very big noise and vibration.
Summary of the invention
In view of this, the present invention is directed to propose a kind of damping vibration combination flywheel, to solve the problems, such as above-mentioned noise and vibration.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of damping vibration combination flywheel, including flywheel main body, flywheel inertia ring and starting gear ring, the outside of the flywheel main body
Several mounting grooves are circumferentially with, flywheel inertia ring is arranged in mounting groove, silicone oil is filled up in mounting groove, the flywheel inertia ring is adopted
With ferrotungsten material；The side outer end of the flywheel main body is installed by the starting gear ring.
Further, the flywheel inertia ring uses ferrotungsten material.
Compared with the existing technology, present invention has the advantage that
The flywheel inertia ring that the present invention installs is placed in silicone oil, has certain cushioning ability, can reduce crankshaft
Twisting vibration and alleviation engine export the impact to gearbox.Using ferrotungsten, guarantee that flywheel there are enough rotary inertias, thus
Engine speed is set to have good output stationarity.
Detailed description of the invention

The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figures 1 to 3, a kind of damping vibration combination flywheel, including flywheel main body 5, flywheel inertia ring 3 and starting gear ring 2, institute
The external circumferential for stating flywheel main body 5 is equipped with several mounting grooves, and flywheel inertia ring 3 is arranged in mounting groove, and silicon is filled up in mounting groove
Oil 4, the flywheel inertia ring 3 use ferrotungsten material；The side outer end of the flywheel main body 5 is installed by the starting gear ring 2.
The flywheel main body 5 is connected to 1 one end of crankshaft by bolt of flywheel 6
Flywheel inertia ring 3 is set to do approximate uniform motion using the viscosity of silicone oil 4, to achieve the purpose that damping, to subtract
The small impact for being transmitted to gearbox, the vibration and noise for improving gearbox are horizontal.
The flywheel inertia ring 3 uses ferrotungsten, guarantees that flywheel has enough rotary inertias, so that there have engine speed to be good
Good output stationarity.
The course of work of the present embodiment is as follows:
As shown in figure 3, flywheel of the present invention will receive lateral impact forces F and twisting resistance from crankshaft 1 during the work time
Square M, lateral impact forces F and torsional moment M are transmitted to the gearbox of clutch and rear end by flywheel.Fig. 2 is conventional flywheel
The power of crankshaft 1 and torque are directly passed to the schematic diagram of clutch by hard parts.Fig. 1 is 3 part of flywheel inertia ring of the present invention
Uniform rotation buffers the power and torque of crankshaft 1.
Flywheel is become by simulation calculation, bending stiffness decline 39.9%, torsion stiffness decline 36.2%, replacement flywheel test
The visible original scheme NVH of Waterfall plot is promoted to 6.5 points from 5.5 points at fast case, improves obviously, as shown in Figure 4 and Figure 5 to NVH.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
