Description
Technical field
The utility model belongs to technical field of engines more particularly to a kind of damper pulley.
Background technique
Automobile engine is the main inherent source that car body generates vibration, and the twisting vibration of engine can not only cause gap
The main reason for hitting and generating impact vibration, even more shaft is caused to be destroyed.Crankshaft is as moving component main in internal combustion engine
One of, its intensity and reliability largely determine the reliability of this internal combustion engine.In order to cut down the twisting vibration of crankshaft,
Present automobile engine is mostly in the maximum crankshaft front end device torsional vibration damper of torsional amplitudes, at present in Crankshaft System of Automobile Engine
What is be widely used in system is rubber damping formula torsional vibration damper, passes through the damping of rubber between the wheel hub and ring gear of damper pulley
Realize damping effect.
At home, as the requirement to internal combustion engine reliability, dynamic property and comfort is higher and higher, existing driving crank
Damper pulley is not able to satisfy requirement of the people to vehicle comfort, for current single-stage rubber torsional vibration damper, mostly with drop
Low crankshaft peak swing is target.Miniaturization and high power recently as automobile engine, vehicle lightweight and biography
Dynamic spaces compact, is driven efficient requirement, and the low resistance by rubber is limited, and single-stage torsional vibration damper can not meet
The control requirement of twisting vibration.
Utility model content
In order to solve the above technical problems, solving the purpose of the utility model is to provide a kind of damper pulley because of rubber
The low resistance of glue limits, and is not able to satisfy high power, the crankshaft system torsion of lightweight engine controls the problem of requiring.
The utility model proposes a kind of damper pulley, first be set on the wheel hub including wheel hub, side by side subtract
Vibration Damper Braces ring and the second damping support ring, be set in the first damping support ring the first belt pulley,
The second belt pulley being set in the second damping support ring, the first damping support ring is interior to be equipped with damping tune
Save ring, the first damping support ring, the first belt pulley, the second damping support ring, the second belt pulley, between wheel hub
Equipped with cavity, silicone oil is equipped in the cavity.
Further, support ring is equipped between first belt pulley and second belt pulley.
Further, the material of the support ring is Teflon.
Further, inertia rings are arranged on first belt pulley.
Further, it is spring steel that the damping, which adjusts the material of ring,.
Further, the material of first belt pulley and the second belt pulley is rubber.
Further, the wheel hub is set on ring flange.
According to the above aspect of the present invention, the utility model at least has the following advantages: the utility model provides a kind of vibration damping belt
Wheel has reached the work of the noise of transmitting, the reduction crankshaft output of reduction crankshaft vibration, the noise level for optimizing entire transmission device
With；By using the mode of filling silicon oil, the heat-sinking capability of whole system is improved, improves the reliable of crank rotation system
Property, extend service life.
Detailed description of the invention
Fig. 1: damper pulley main view.
Fig. 2: Fig. 1 A-A cross-sectional view.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawing, the description of this part be only it is exemplary and explanatory,
There should not be any restriction effect to the protection scope of the utility model.
As depicted in figs. 1 and 2, a kind of damper pulley, including ring flange 1, the wheel hub being set on ring flange 12.
The first damping support ring 3 and the second damping support ring 4 are arranged on wheel hub 2 side by side.The resistance of first vibration damping
It is arranged with the first belt pulley 5 in Buddhist nun's support ring 3, the second belt pulley 6 is arranged in the second damping support ring 4.First vibration damping
It is equipped with damping in Damper Braces ring 3 and adjusts ring 7.Support ring 8 is equipped between first belt pulley 5 and the second belt pulley 6.
First damping support ring 3, the first belt pulley 5, damping adjust ring 7, the second damping support ring 4, second
Belt pulley 6, support ring 8 are equipped with cavity between wheel hub 2, are equipped with silicone oil 9 in cavity.
Inertia rings 10 are arranged on first belt pulley 5.
The material of support ring 8 is Teflon.The material that damping adjusts ring 7 is spring steel.First belt pulley 5 and the second belt
The material of wheel 6 is rubber.
The working principle of the utility model are as follows: in Crankshaft motion, the first damping support ring 3, damping adjust ring 7,
First belt pulley 5, the second damping support ring 4 and the second belt pulley 6 are used as level-one damper mechanism, to reduce the vibration of crankshaft
Amplitude increases the diameter that damping adjusts ring 7 if the demand of level-one vibration damping is bigger, to increase the rigidity of damper pulley,
In the biggish situation of crankshaft output power, the morphotropism of damper pulley is reduced, reduces the shake of damper pulley.Silicone oil 9
As second level damper mechanism, damper pulley absorbs the vibration of disturbance torque input system by the viscous damping of 9 liquid of silicone oil
Energy, at normal temperature, the viscosity of silicone oil 9 are big, and semi-solid state, when Crankshaft motion, the temperature liter of damper pulley is presented
Height, silicone oil 9 become liquid, and in damper pulley rotary course, silicone oil 9 is got rid of the outside to cavity by centrifugal force, are subtracted with increasing
Quality on the outside of vibration belt pulley facilitates damper pulley and keeps inertia balance.
Support ring 8 further increases the rigidity of damper pulley, has both the effect of sealing silicone oil 9.Inertia rings 10 increase
The inertia of damper pulley, so that damper pulley overall operation is more steady, it is smooth.Silicone oil 9 also improves whole system
Heat-sinking capability, extend the service life of crank rotation system.
To sum up, the damper pulley of the offer of the utility model mixes damper mechanism by using two-stage, meets car
The lightweight of engine and the requirement of high-power crankshaft system Torsional Vibration Control.
Although the utility model has been described by way of example and in terms of the preferred embodiments, it is not intended to limit the utility model, any
Person skilled in the art can do various change and modification, therefore this without departing from the spirit and scope of the utility model
The protection scope of utility model should subject to the definition of the claims.
