When in use, the control system drives the driving disc 3 by the driving transmission fork 10; the driving disc 3 is matched with the transmission fork 4 in a sliding way; therefore, when the driving disc 3 rotates, the transmission fork 4 can be driven to rotate and can drive the blade 1 to rotate, thus changing the angle of the blade and adjusting the airflow section so that the engine can work effectively at all frequency bands under the supporting 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 anti-jamming 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, 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, higher, the better conventional driving anti-jamming variable-area nozzle ring member of blade action consistency of reliability when the utility model proposes under a kind of high temperature high-speed motion.
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, position limit pin, roller pin, roller, roller pin, active shift fork, distance screws, band shoulder nut and bonnet.Wherein: blade is contained in the mounting disc, forms the nozzle ring weldment jointly with the shift fork solid welding then; Drive plate by roller, roller pin, roller pin radially, be fixed in the mounting disc and between the shift fork after the axially locating and be slidingly matched; Drive plate is provided with restraining groove, and position limit pin is fixed in the mounting disc and cooperates with restraining groove on the drive plate; Drive plate is provided with and active shift fork corresponding groove, and initiatively shift fork is placed directly in the drive plate corresponding groove; Bonnet is fixed in the mounting disc by distance screws and band shoulder nut.
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: overall structure is compacter, the blade action consistency is better, the assembly high-temperature reliability is higher, the application of roller, roller pin, position limit pin makes drive plate from radially, axially and stir three aspects of scope and all be effectively controlled, it is movable and stuck to prevent that drive plate from surpassing, and helps nozzle ring assembly stable operation and improves speed of response.
