Description
Technical field
The utility model relates to turbo-charger technical field, particularly a kind of integrated type variable nozzle ring that is used on the turbosupercharger.
Background technique
Supercharging technology is one of major measure that improves engine power performance, and most widely used be to adopt turbocharging technology.Turbosupercharger is to utilize the energy of motor combustion gas, becomes mechanical work through turbine, drives turbine wheel and rotates; The compressor impeller coaxial with turbine wheel also runs up with same speed, after compresses fresh air, sends into cylinder; Improve the air density and the aeration quantity of cylinder, thereby improved the power of motor, improved the combustion condition of fuel oil; Fuel oil is fully burnt, thereby reduced fuel consume, reduced the ratio of Toxic in the waste gas that enters atmosphere; And then finally realize environmental protection and energy saving, improve the effect of engine power.
Yet vehicle turbocharger should have broad operating range; Because when time of engine low speed, because the energy that waste gas provides seldom, the rotating speed of turbosupercharger is too low; Boost pressure that is difficult to provide suitable and sufficient air inflow also just are difficult to produce bigger torque; Be again motor when running up because delivery temperature and pressure are very high, may cause pressurized machine to exceed the speed limit.In addition, owing to the hysteresis of pressurized machine response, make that the response of the response ratio air inflow supply that oil mass is supplied with in transient process is fast, and therefore cause the transient response performance difference of motor and the acceleration of smoldering.In order to address these problems, people have adopted many methods such as reducing pressurized machine rotary inertia, installation waste gas bleed valve, auxiliary air injection, adjusting nozzle ring aperture.Regulating the method for nozzle ring aperture approves because of with the obvious advantage having obtained of its engine performance improvement widely.Adopt the variable nozzle ring turbosupercharger to compare with adopting common pressurized machine, the low speed torque of motor, smoke intensity and oil consumption all are improved.
Existing variable nozzle ring shown in accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, it comprise a driving ring 1, three supporting wheels 2, three support 3,11 driven Rocker arm 4s of wheel shaft, 11 blades 5, blade seat 6, three 7 and nozzle carriers 8 of step pin.Supporting wheel 2 is installed on the blade seat 6 through supporting wheel shaft 3, adopts Spielpassung between supporting wheel 2 and the support wheel shaft 3, supports between wheel shaft 3 and the blade seat 6 and adopts Spielpassung.Blade 5 is fixedly mounted on the blade seat 6 through welding with driven Rocker arm 4, adopts Spielpassung between blade 5 and the blade seat 6.Driving ring 1 is assemblied in the draw-in groove of 3 supporting wheels 2.In the pin hole that step pin 7 is installed on the blade seat 6, the pin hole on step pin 7 and the blade seat 6 adopts Spielpassung.Be used for nozzle carrier 8 is installed in the screw peace hole on the turbo-charger bearing body being provided with three on the nozzle carrier 8.
Not enough below existing variable nozzle ring exists: the one, most of component all are separation members, and the component assembling is loaded down with trivial details, and efficient is low; The 2nd, when on turbosupercharger, variable nozzle ring being installed; Not only nozzle carrier 8 will be installed on the turbo-charger bearing body through screw; And on the turbo-charger bearing body, to assemble position limit pin, and so just increased bearing support manufacturing procedure and assembly process, increased number of spare parts simultaneously.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of existing technology and a kind of integrated type variable nozzle ring is provided.
The technological scheme of the utility model is: a kind of integrated type variable nozzle ring, it comprises a driving ring, three supporting wheels, three support wheel shafts, a plurality of driven rocking arm, plurality of vanes, a blade seat, three step pins, a bonnet and three interval pins.Supporting wheel is installed on the blade seat through supporting wheel shaft, adopts interference fit between supporting wheel and the support wheel shaft, supports between wheel shaft and the blade seat and adopts interference fit.During assembling, two supporting wheels in three supporting wheels are separately positioned between any two driven rocking arms, a supporting wheel is arranged on the movable maximum position of the driven rocking arm of restriction, and another supporting wheel is arranged on the movable minimum position of the driven rocking arm of restriction.Blade and driven rocking arm are evenly distributed on the both sides of blade seat, and the corresponding driven rocking arm of blade is fixedly mounted on the blade seat through welding between blade and the driven rocking arm, adopts Spielpassung between blade and the blade seat.Driving ring is assemblied in the draw-in groove of three supporting wheels.The step pin is installed in the pin hole on the blade seat, and the pin hole on step pin and the blade seat adopts Spielpassung.It is in aggregates that bonnet and blade seat are connected through three equally distributed spacer pin closing ups, so just is equivalent to driving ring, supporting wheel, support wheel shaft, driven rocking arm, blade, blade seat, bonnet, spacer pin bound be made into an integral body.
Described driven rocking arm is nine～13, and described blade is nine～13.
During use, the integrated type variable nozzle ring is installed on the turbo-charger bearing body through the pin of the step on the blade seat, and the pin hole on step pin and the turbo-charger bearing body adopts Spielpassung.During work; Blade on the nozzle ring can rotate around axle center separately jointly; Change along with nozzle ring upper blade angle; Angle and speed that minimum actual internal area of turbo machine and exhaust get into turbine all will change, thereby change the rotating speed of turbo machine and the boost pressure of blower outlet end.During time of engine low speed, the blade on the nozzle ring is rotated counterclockwise, and nozzle ring cross-sectional is long-pending to be reduced, and secondary speed rises, and boost pressure increases, boost pressure when having guaranteed the slow-speed of revolution and air inflow; During the high engine speeds running, the blade on the nozzle ring turns clockwise, and nozzle ring cross-sectional is long-pending to be increased, and secondary speed descends, and prevents the pressurized machine hypervelocity.When motor quickened, in order to improve the speed of response of pressurized machine, it was long-pending to reduce nozzle ring cross-sectional, improves supercharger speed, thereby improved boost pressure and air inflow, the air inlet requirement when satisfying transient working.
The utility model compared with prior art has following characteristics:
1, the integrated type variable nozzle ring that provides of the utility model has been cancelled nozzle carrier on existing variable nozzle ring basis, through pin at interval with bonnet with is connected in aggregatesly with the blade seat riveted, make integral body of whole variable nozzle ring formation.
