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 in especially a kind of dish side
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.But the nozzle ring assembly type of belt drive at the initial stage of improvement is conventional driving, drive plate was relaxed with connecting comparatively of inter-module, walk or hidden danger such as blade skids off, blade incoordinate movement under the high temperature, and the energy loss of airflow strikes on blade is bigger, and efficient is not high enough.
Summary of the invention
At the deficiency of above-mentioned technology, reliability is higher when the utility model proposes under a kind of high temperature high-speed motion, resistance to motion is littler, the better driving variable-area nozzle ring member in the side of coiling of blade action consistency.
The technological scheme that the technical problem that the utility model solves is taked is: it is made up of bonnet, blade, distance screws, mounting disc, shift fork, driving side, packing ring, driven pin, drive plate, active pin, masters and active packing ring, wherein: blade is contained in the mounting disc, forms the nozzle ring weldment with the shift fork solid welding; Driving side, packing ring are welded on the drive plate after connecting by driven pin, and masters, active packing ring are welded on the drive plate after connecting by the active pin, welding back composition drive plate weldment; The drive plate weldment directly is enclosed within the mounting disc, can freely rotate; Driving side is placed in the shift fork, and both are for being slidingly matched; Bonnet is fixed in the mounting disc by distance screws.
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, improve the mapping of motor, guarantee the technical-economic index and the emission performance of motor.
The utility model has the advantages that: resistance to motion is littler, the compacter blade action consistency of transmission is better, and the assembly high-temperature reliability is higher, has reduced the relative friction forces between drive plate and shift fork, required driving is littler, helps nozzle ring assembly stable operation and improves speed of response.
