Abstract
The utility model discloses a generally-driven nozzle ring component with a changeable section, which has an adjustable blade angle and can work reliably under the circumstance of high temperature and high-speed movement. The nozzle ring component comprises a blade 1, a mounting plate 2, a drive plate 3, a shift fork 4, a roller 5, a roller pin 6 and a driving shift fork 7; the blade 1 is mounted in the mounting plate 2; the shift fork 4 is fixedly welded to form a nozzle ring weldment 9; the drive plate 3 is fixed on the mounting plate 2 via the roller 5 and the roller pin 6; the drive plate 3 and the shift fork 4 are in slide fit; and the driving shift fork 7 is directly arranged in a groove 8 corresponding to the drive plate 3. When the nozzle ring component is in operation, the driving shift fork 7 drives the drive plate 3 to rotate, thereby driving the shift fork 4 to rotate; and the shift fork 4 drives the blade 1 to rotate, thereby altering the angle of the blade1 and adjusting the airflow section. Therefore, an engine can operate more efficiently at all powers with the support of a supercharger.
Description
Technical field
The utility model relates to a kind of auto parts and components, is applied to engine supercharger, the driving variable-area nozzle ring member of especially a kind of routine.
Background technique
Turbosupercharging is one of developing direction of world's internal-combustion engine technology, 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, and pressurized machine can only make motor in the interval efficient operation of some power.
Summary of the invention
At the deficiency of fixed-area nozzle ring member technology, it is adjustable to the utility model proposes a kind of blade angle, conventional driving variable-area nozzle ring member that can reliably working during high-speed motion under the high temperature.
The technological scheme that the technical problem that the utility model solves is taked is: it is made up of blade, mounting disc, drive plate, shift fork, roller, roller pin and active shift fork.Wherein: blade is contained in the mounting disc, forms the nozzle ring weldment jointly with the shift fork solid welding then; Drive plate be fixed in the mounting disc by roller and roller pin and between the shift fork for being slidingly matched; Drive plate is provided with and active shift fork corresponding groove, and initiatively shift fork is placed directly in the drive plate corresponding groove.
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 blade angle is adjustable, thereby the nozzle ring weldment changes blade angle, regulates flow area by the drive plate driven rotary, motor can both be worked on more efficient ground in each power section under the support of pressurized machine.
Description of drawings
Fig. 1 is the utility model sectional structure schematic representation
Fig. 2 is the plan view of Fig. 1
Among the figure 1, blade 2, mounting disc 3, drive plate 4, shift fork 5, roller 6, roller pin 7, initiatively shift fork 8, groove 9, nozzle ring weldment
Embodiment
In Fig. 1 and Fig. 2: blade 1 is contained in the mounting disc 2, forms nozzle ring weldment 9 jointly with shift fork 4 solid weldings; Drive plate 3 is fixed in the mounting disc 2 by roller 5 and roller pin 6; Initiatively shift fork 7 is placed directly in drive plate 3 corresponding groove 8.During work, control system drives drive plates 3 by active shift fork 7,4 of drive plate 3 and shift forks are for being slidingly matched, when therefore drive plate 3 rotates, will drive shift fork 4 rotations, 1 rotation of shift fork 4 drive blades, thus blade angle, adjusting flow area changed, motor can both be worked on more efficient ground in each power section under the support of pressurized machine.
