Description
Technical field
The present invention relates to a kind of turbocharger, use 8-13 to rise electromotor particularly to one
Heavy truck use variable-area turbocharger.
Background technology
Along with rising steadily of crude oil price, the continuous deterioration of air quality, wanting of energy-saving and emission-reduction
Asking and be mentioned again and again, the discharge policy of country is the most constantly tightened up.But the discharge of country
Policy can only restrict automobile and the electromotor of new production, and the automobile being presently using, especially
It is that heavy truck remains unchanged " gulp down oil and tell cigarette " every day, constantly pollutes our society and home.
So how these societies are possessed vehicle carry out " serving parents while living and give proper burial after death " be also one the most arduous
Task.
Turbocharger is that the size of the exhaust energy utilizing electromotor is to control turbocharger
Rotating speed, thus by air compression enter electromotor, improve burning effect.
Existing second filial generation turbocharger is the mechanism of venting valve type.Electromotor is at the low rotational speed
During operation, owing to the exhaust energy of electromotor is not enough, turbo charger speed is the lowest, supercharger
The air provided for electromotor is the most insufficient, and engine combustion is also the most insufficient；High at electromotor
In the case of rotating speed operation, the exhaust energy of electromotor is too much, for the sake of security, in addition it is also necessary to logical
The unlatching crossing vent valve discharges a part of waste gas.And electromotor is at the sky of different duties
The demand of gas is different.The turbocharger of the venting valve type of the current second filial generation is to starting
The control of machine air demand is the most dull.So it cannot be in the situation of low engine speeds
Under, provide enough compressed airs for electromotor.So electromotor arises that burning is insufficient
Phenomenon, heavy truck arises that over-emitting black exhaust, start to walk slow phenomenon.And the most also
It is not specifically designed for 8-13 and rises the variable-area turbocharger of heavy duty truck engine, heavy
Truck is but oil consumption rich and influential family, is also one of the major reason of air pollution, therefore, and design one
Can apply to the variable-area turbocharger in heavy truck significant.
Summary of the invention
The technical problem to be solved in the present invention is: provide the turbocharger of a kind of heavy truck.
For solving above-mentioned technical problem, the technical scheme is that
A kind of variable-area turbocharger of heavy truck, the turbine case of turbocharger with in
Between be provided with nozzle ring between shell, described nozzle ring include mounting disc, shifting fork disc, actively shift fork,
Little shift fork and blade；Mounting disc and shifting fork disc are parallel to each other, between connect with roller pin；Roller
Pin is connected with actively shift fork near one end of mounting disc, and actively shift fork is rotatable by installing screw
Be assemblied in mounting disc, screw is installed through mounting disc, nozzle ring is fixed on turbine case；
Blade is connected by shifting fork pin and little shift fork one；Little shift fork is connected by connecting shaft and shifting fork disc
Connect；The corresponding blade of each little shift fork；Actively shift fork external connection power device, it is possible to drive
Actively shift fork, thus drive shifting fork disc to horizontally rotate relative to mounting disc, thus drive little shift fork
Horizontally rotate with blade.
Preferably, in order to ensure the gap of blade, several spacer sleeves can be set between blade.
Preferably, the external diameter of described nozzle ring is 100-160mm.For 8-13 liter capacity
Truck engine, the size of nozzle ring only could both reach in a specific fitting limit
The effect of energy-saving and emission-reduction, meets again the requirement of existing narrow installation space, grinds through widely
Study carefully and find that the footpath size (Ф D) of nozzle ring is relatively reasonable in the range of 100-160mm, outward
Footpath can cause nozzle ring to install more than 160mm；External diameter can cause nozzle less than 100mm
Ring is unable to reach again due effect.
Preferably, consider heavy truck the power bracket of electromotor, the leaf of nozzle ring
Sheet quantitative design is 11-17.Blade is as the core component of nozzle ring capable of changing cross sections, theoretical
Upper quantity is The more the better, because so airflow direction is easier to flow along the direction of blade,
So the direction of air-flow is closer to our Design Theory direction；But practical situation is blade
Operating temperature is the highest, typically at 600-1000 DEG C, so blade must have certain thickness
And length, adding blade also to have certain revolution space, so through extensively experiment, I
Find in the truck engine of 8-13 liter capacity, arranging 11-17 blade is rational district
Between.
Preferably, the height of jet blade should control between 5-12mm, if using height
Degree is the blade more than 12mm, the flowing of waste gas in turbine case less than 5mm or blade height
Speed all can be higher or on the low side, so can directly affect air demand and the aerofluxus temperature of electromotor
Degree, if temperature has reached the temperature of the limit, it is more likely that can damage electromotor.
In another aspect of this invention, it is provided that the variable-area turbocharger of the present invention exists
Application on the truck engine of 8-13 liter capacity.
The beneficial effects of the present invention is the truck engine specialized designs for 8-13 liter capacity
Third generation variable-area turbocharger matches, and has filled up industry blank, has promoted original
The power of electromotor, reduces fuel consumption, reduces the exhaust emission of discharge；Variable cross section
Nozzle ring produce as the core component of turbocharger, its concrete element size, angle
Small change may result in engine efficiency and reduces, and even cannot normally work, the present invention's
Some design parameters, inventor just determines after experience numerous experiments just, is conscientiously may be used
Operation, there is the highest practical value.
