Abstract
The invention discloses a poking disc bi-directional positioning blade double-supporting variable-section nozzle ring assembly which enables a poking disc to be reliably positioned in axial and radial directions, protects the a poking disc from deformation and mis-positioning when a load is large at high temperature, and prevents a shift fork from be dropped out of the poking disc due to the deformation or mis-positioning of the poking disc. The nozzle ring assembly is composed of a rear cover 1, a spring piece 2, a blade 3, a spacer sleeve 4, a mounting disc 5, a heat insulation support disc 6, the poking disc 7, a limiting disc 8, the shift fork 9 and a limiting pin 10. The poking disc 7 is placed in a restricted space formed by the heat insulation support disc 6 and the limiting disc 8, and the poking disc 7 is positioned in the axial and radial directions. The heat insulation support disc 6 and the limiting disc 8 are welded to the mounting disc 5 through the spacer sleeve 4, and the shift fork 9 is directly placed in a notch 11 corresponding to the poking disc 7. The head of the blade 3 is inserted into the rear cover and can freely rotate, the tail of the blade 3 is installed in the mounting disc 5 to be welded to the shift fork 9, the limiting pin 10 is directly inserted into the mounting disc 5 to be fixed, and the rear cover 1 is fixed on the mounting disc 5 through the spacer sleeve 4. The rear cover 1, the mounting disc 5 and the blade 3 form a variable-section flow channel. In work, the poking disc 7 is subjected to external force driving. Due to the fact that the poking disc 7 is in sliding fit with the shift fork 9, when the poking disc 7 rotates, the shift fork 9 is driven to rotate, the shift fork 9 drives the blade 3 to rotate, so that a blade angle is changed, the airflow section is adjusted, and an engine can efficiently work at each power section under support of a supercharger.
Description
Technical field
The present invention relates to a kind of auto parts and components, be applied to engine supercharger, the two-way locating blade dual-gripper of especially a kind of shifting disc nozzle ring component with variable cross section.
Background technique
Turbosupercharging is one of developing direction of world's internal-combustion engine technology, is the main approach that current internal-combustion engine is strengthened, and turbocharging technology can increase substantially engine output, and energy saving reduces engine exhaust and pollutes.and nozzle ring component with variable cross section is the critical component in current advanced variable geometry turbocharger, the blade angle that before is used for engine supercharger nozzle ring assembly is fixed, blade is non-adjustable, pressurized machine can only make motor in the interval efficient operation of some power, it is adjustable that my company takes the lead in that at home the nozzle ring modular construction is improved to blade angle, thereby blade and shift fork soldering member change blade angle by the drive plate driven rotary, regulate flow area, make motor under the support of pressurized machine each power section can more efficient ground work (the nozzle ring assembly patent No.: ZL 2,006 1 0163404.8).Nozzle ring assembly after improvement is Double-disc-supported variable-section nozzle ring component (the nozzle ring assembly patent No.: ZL 2,010 20144255.2), allow pressurized machine work efficiently thereby can adjust quickly and efficiently throughput, blade-section stable working state, high temperature reliability are high.But the shifting disc of Double-disc-supported variable-section nozzle ring component is not upwards reliably located in axial and footpath, easily deform and walk when at high temperature load is larger, the shift fork that is mated can be because the distortion of shifting disc or walk and therefrom come off out, thereby causes the nozzle ring assembly to drive and stuck.
Summary of the invention
Deficiency for above-mentioned technology, the present invention proposes a kind of shifting disc that can allow upwards reliably locates in axial and footpath, preventing from high temperature loading, shifting disc deforms and walks when larger, prevents shift fork because the distortion of shifting disc or the two-way locating blade dual-gripper of the shifting disc nozzle ring component with variable cross section that walks and therefrom come off out.
the technological scheme that the technical problem that the present invention solves is taked is: it is comprised of bonnet, spring sheet, blade, spacer sleeve, mounting disc, heat insulation support dish, shifting disc, position-arresting disk, shift fork, position limit pin, wherein: shifting disc is placed in the restriceted envelope of heat insulation support dish and position-arresting disk formation, heat insulation support dish and position-arresting disk are welded in mounting disc by spacer sleeve, and shifting disc has just obtained axially and two-way location radially thus, shifting disc is provided with the notch corresponding with shift fork, and shift fork is placed directly in notch corresponding to shifting disc, and can freely rotate in notch and slide, blade is carried out mounting disc and bonnet dual-gripper, the quantity of blade is 9-19, the head of blade is inserted in bonnet and can freely rotate, the afterbody of blade is contained in mounting disc and welds with shift fork, the shape of blade can be selected my company's design patent: streamline symmetric form (ZL200930185904.6), straight line symmetric form (ZL200930185915.4), air-driven type (ZL200930090768.2, ZL200930090764.4) etc., position limit pin directly inserts in mounting disc fixing, prevent that the shift fork forward stroke is excessive and it is excessive to drive blade opening, prevent that simultaneously the leaf tip part of blade from encountering turbine and causing that turbine or nozzle ring assembly destroy, bonnet is fixed in mounting disc by spacer sleeve, and spring sheet is housed on bonnet, passes through the spring sheet axially locating when time in the shell of bonnet insertion turbosupercharger, allows whole nozzle ring assembly be fixed on turbosupercharger.
The working principle of variable geometry turbocharger is: realize and the optimum Match of motor under every speed by the flow area that changes turbine.During motor slow-speed of revolution running, the rotary spray nozzle ring blade is regulated the turbine inlet sectional area, secondary speed rises, and boost pressure increases, the boost pressure when having guaranteed the slow-speed of revolution and air inflow, improve air fuel ratio, made full combustion of fuel, prevented the generation of over-emitting black exhaust problem; During the high rotation speed operation of motor, the opposite spin nozzle blade increases nozzle ring cross-sectional long-pending, and secondary speed descends, and prevents the pressurized machine hypervelocity.When motor accelerated, the rotary spray nozzle ring blade was long-pending to reduce nozzle ring cross-sectional, improves rapidly supercharger speed, thereby has improved the transient response of pressurized machine.Nozzle blade in the nozzle ring assembly can be according to the working condition requirement of motor, accept the angle of swing of instruction (or according to boost pressure) adjusting vane of electronic engine management system, keep best combustion gas Flow area, make turbine be in all the time high efficient area work, thereby guarantee the working conditions change of the timely responding engine of pressurized machine, the mapping of raising motor, guarantee technical-economic index and the emission performance of motor.
Advantage of the present invention is: position-arresting disk and heat insulation support dish be to the location that shifting disc has carried out axially and the footpath makes progress, and can prevent from that shifting disc from high temperature loading walk and be out of shape when larger; Blade is carried out mounting disc and bonnet dual-gripper, improved the force-bearing situation of blade, can prevent that blade from high temperature loading the blade rotor distortion occurs when larger.Thereby avoided the nozzle ring assembly at high temperature and high load working condition lower shift fork because the distortion of shifting disc or walk therefrom to come off out and cause that the nozzle ring assembly can't drive and stuck situation occurs.In addition, the heat insulation support dish also plays heat-blocking action, can allow the temperature of shift fork and this side of shifting disc be starkly lower than the temperature of blade-side, creates better operating mode for assembly, has effectively prevented the high temperature deformation of shifting disc and has walked.
