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 compact dish type drives pulley pneumatic paddle 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.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, it is compacter to the utility model proposes a kind of transmission, and the blade action consistency is better, and can reduce the higher compact dish type driving of energy loss, the efficient of airflow strikes on blade has pulley pneumatic paddle variable-area nozzle ring member.
The technological scheme that the technical problem that the utility model solves is taked is: it is made up of turbine lining, screw, bonnet, spacer sleeve, mounting disc, pulley positioning ring, pulley, drive plate, shift fork and blade, wherein: blade is contained in the mounting disc, with the shift fork solid welding, they and pulley positioning ring, pulley are formed the nozzle ring weldment jointly then; Drive plate directly is enclosed within the mounting disc, is provided with groove above; The pulley transition is arranged between drive plate and the mounting disc, and pulley is by pulley positioning ring fixed position, and the pulley positioning ring directly is enclosed within the mounting disc, can freely rotate; After blade and shift fork solid welding, the position of drive plate, pulley positioning ring and pulley is fixed in weldment; In mounting disc, the turbine lining is fixed on the bonnet bonnet by spacer sleeve and screw.Blade is our company's design patent (patent No.: 2009300907644), be that the gas flowfield in the simulated condition designs.
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: transmission is compacter, and the blade action consistency is better, and the high temperature reliability of assembly is higher, and required driving force is littler, can reduce the energy loss of airflow strikes on blade effectively, obtains more high efficiency.
Description of drawings
