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, especially a kind of shifting disc two-way locating blade dual-gripper nozzle ring component with variable cross section.
Background technique
Turbosupercharging is one of developing direction of world's internal-combustion engine technology, and be the main approach of current internal-combustion engine strengthening, turbocharging technology can increase substantially engine output, 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, blade angle before for engine supercharger nozzle ring assembly is fixed, blade is non-adjustable, pressurized machine can only make motor efficiently work at some power interval, my company takes the lead in nozzle ring modular construction to be improved to adjustable blade burner at home, blade and shift fork soldering member lean on drive plate driven rotary thus change blade angle, regulate flow area, make motor can work to more efficient (the nozzle ring assembly patent No.: ZL 2,006 1 0163404.8) in each power section under the support of pressurized machine.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), can adjust throughput quickly and efficiently thus allow pressurized machine work efficiently, 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 reliably located in axis and radial direction, easily deform when at high temperature load is larger and walk, the shift fork that is mated can because the distortion of shifting disc or walk and therefrom come off out, thus causes nozzle ring assembly to drive and stuck.
Summary of the invention
For the deficiency of above-mentioned technology, the present invention proposes one can allow shifting disc reliably locate in axis and radial direction, when preventing that at high temperature load is larger, shifting disc deforms and walks, and prevents shift fork because the distortion of shifting disc or the shifting disc two-way locating blade dual-gripper nozzle ring component with variable cross section therefrom coming off out that walks.
The technological scheme that the technical problem that the present invention solves is taked is: it is made up 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 just obtains axially and radial two-way location 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, mounting disc and bonnet dual-gripper are carried out to blade, the quantity of blade is 9-19, the head of blade to be 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 select 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 shift fork forward stroke excessive and drive blade opening excessive, prevent the leaf tip part of blade from encountering turbine simultaneously and cause turbine or nozzle ring component failures, bonnet is fixed in mounting disc by spacer sleeve, and bonnet is equipped with spring sheet, when bonnet inserts in the shell of turbosupercharger by spring sheet axially locating, allows whole nozzle ring assembly be fixed in turbosupercharger.
The working principle of variable geometry turbocharger is: realized and motor optimum Match at each speed by the flow area changing turbine.During low engine speeds running, rotary spray nozzle ring blade, regulates turbine inlet sectional area, secondary speed rises, and boost pressure increases, boost pressure when ensure that the slow-speed of revolution and air inflow, improve air fuel ratio, make full combustion of fuel, prevent the generation of over-emitting black exhaust problem; During motor high rotation speed operation, opposite spin nozzle blade, increase nozzle ring cross-sectional and amass, secondary speed declines, and prevents pressurized machine from exceeding the speed limit.When motor accelerates, rotary spray nozzle ring blade amasss to reduce nozzle ring cross-sectional, improves supercharger speed rapidly, thus improves the transient response of pressurized machine.Nozzle blade in nozzle ring assembly can 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, turbine is made to be in high efficient area work all the time, thus ensure 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 have carried out the location in axial and radial direction to shifting disc, can prevent shifting disc from walking when at high temperature load is larger and being out of shape; Mounting disc and bonnet dual-gripper are carried out to blade, improves the force-bearing situation of blade, can prevent blade from when at high temperature load is larger, blade rotor distortion occurring.Thus avoid 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 nozzle ring assembly cannot drive and stuck situation occurs.In addition, heat insulation support dish also plays heat-blocking action, and the temperature of shift fork and this side of shifting disc can be allowed to be starkly lower than the temperature of blade-side, for better operating mode created by assembly, effectively prevent the high temperature deformation of shifting disc and walks.
