Abstract
The utility model discloses a double-disc-supported variable-section nozzle ring component, which can prevent a driving disc from deforming when in heavy load at high temperature and further prevent a blade rotating shaft of blades from deforming when in heavy load at high temperature. The double-disc-supported variable-section nozzle ring component consists of a driving disc 1, a mounting disc 2, blades 3, a supporting disc 4, a notch 5, a driving block 6, a supporting wheel 7, a supporting shaft 8 and a shifting fork 9, wherein the supporting shaft 8 is inserted into the mounting disc 2, the supporting wheel is sleeved on the supporting shaft 8, the driving disc 1 is sleeved on the supporting wheel 7 to be fixed axially and radially, the driving block 6 is welded in the driving disc 1 to be integrally connected with the same, the notch 5 is arranged on the driving disc 1 at the position corresponding to the driving block 6, tails of the blades 3 are mounted in the mounting disc 2 to be fixedly welded with the shifting fork 9, and heads of the blades 3 are inserted in the supporting disc 4 to be fixed axially and radially. The driving disc 1 is in sliding fit with the shifting fork 9, when the driving disc 1 rotates, the shifting fork 9 can be driven to rotate, the shifting fork 9 drives the blades 3 to rotate, so that angles of the blades are changed, airflow section is adjusted, and an engine can be in operation with higher efficiency at various power sections, with the support of a booster.
Description
Technical field
The utility model relates to a kind of auto parts and components, is applied to engine supercharger, and especially a kind of double plate supports the variable-area nozzle ring member.
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 the variable-area nozzle ring member is the critical component in the 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 the motor can both more efficient ground work (number of patent application: 200610163404.8) under the support of pressurized machine in each power section.Nozzle ring assembly type of belt drive after the improvement is conventional driving, thereby can adjust throughput quickly and efficiently allows pressurized machine work efficiently, but the comparatively thin load at high temperature of the drive plate of conventional driving nozzle ring assembly easily deforms when big, its blade is that single-deck supports the blade rotor distortion easily takes place when at high temperature load is big, and above-mentioned 2 can to cause rotation not smooth even stuck.
Summary of the invention
At the deficiency of above-mentioned technology, the utility model proposes a kind of can preventing and deform when drive plate from high temperature loading greatly, prevent that blade from the double plate support variable-area nozzle ring member of blade rotor distortion taking place when at high temperature loading greatly.
The technological scheme that the technical problem that the utility model solves is taked is: it is made up of drive plate, mounting disc, blade, supporting disk, notch, driving block, supporting wheel, back shaft, shift fork, wherein: back shaft is inserted in the mounting disc, supporting wheel is enclosed within on the back shaft, and drive plate is enclosed within and obtains on the supporting wheel axially and radially fixing; Driving block is welded in the drive plate and fuses with it, is provided with notch at drive plate and driving block corresponding part; The afterbody of blade is contained in the mounting disc and the shift fork solid welding, and the head of blade inserts and obtains in the supporting disk axially and radially fixing.
The working principle of variable geometry turbocharger is: realize and the optimum Match of motor under each rotating speed by the flow area that changes turbine.During the running of engine low rotation speed, swivel nozzle ring blade is regulated the turbine inlet sectional area, secondary speed rises, and boost pressure increases, 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, it is long-pending to increase nozzle ring cross-sectional, and secondary speed descends, and prevents the pressurized machine hypervelocity.When motor quickened, swivel nozzle ring blade was long-pending to reduce nozzle ring cross-sectional, improves supercharger speed rapidly, 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 high efficient area work all the time, thereby guarantee the working conditions change of the timely responding engine of pressurized machine, the mapping of raising motor, guarantee the technical-economic index and the emission performance of motor.
The utility model has the advantages that: welded driving block on the drive plate and reinforced, can prevent to deform when drive plate from high temperature loading greatly; Blade is carried out mounting disc and the support of supporting disk double plate, improved the force-bearing situation of blade, can prevent that blade from the blade rotor distortion taking place when at high temperature loading greatly.Thereby having avoided the nozzle ring assembly to rotate smooth even not stuck situation under high temperature and high load working condition takes place.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified
Fig. 1 is the utility model sectional structure schematic representation
Fig. 2 is the right elevation of Fig. 1
Among the figure: 1, drive plate 2, mounting disc 3, blade 4, supporting disk 5, notch 6, driving block 7, supporting wheel 8, back shaft 9, shift fork
Embodiment
In Fig. 1 and Fig. 2: back shaft 8 is inserted in mounting disc 2, and supporting wheel 7 is enclosed within on the back shaft 8, and drive plate 1 is enclosed within and obtains on the supporting wheel 7 axially and radially fixing; Driving block 6 is welded in the drive plate 1 and fuses with it, is provided with notch 5 in drive plate 1 and driving block 6 corresponding parts; The afterbody of blade 3 is contained in the mounting disc 2 and shift fork 9 solid weldings, and the head of blade 3 inserts and obtains in the supporting disk 4 axially and radially fixing.So far, supporting disk 4, mounting disc 2 and blade 3 have been formed the variable cross section runner; The head of pitman arm shaft is placed directly in the driving block 6 corresponding notches 5, and driving block 6 obtains power by the head of pitman arm shaft with outside the connection.During work, control system is stirred driving block 6 by the head of pitman arm shaft, and driving block 6 fuses with drive plate 1, thus drive plate 1 rotate, thereby drive shift fork 9,9 of drive plate 1 and shift forks are for being slidingly matched, when therefore drive plate 1 rotates, will drive shift fork 9 rotations, shift fork 9 drives blades 3 rotations, thereby change blade angle, regulate flow area, motor can both be worked on more efficient ground in each power section under the support of pressurized machine.
