Abstract
The utility model provides a disc column driving type variable cross section spray nozzle ring assembly with high reliability and small moving resistance force during high-speed movement at a high temperature. The disc column driving type variable cross section spray nozzle ring assembly consists of a driving disc welding element 2, a shifting fork 3, an installing disc 4, a fixed distance screw 5, a back cover 6, a blade 7 and a driving column 8. The utility model is characterized in that the driving disc element 2 is directly sheathed on the installing disc 4, the driving column 8 is welded on the driving disc welding element 2, the driving column 8 is directly placed in the shifting fork 3, and the driving column 8 and the shifting fork 3 are matched glidingly. When the disc column driving type variable cross section spray nozzle ring assembly works, a control system toggles the driving disc welding element 2 through a driving shifting fork. When the driving disc welding element 2 rotates, the shifting fork 3 can be driven to rotate through the driving column 8, and the shifting fork 3 drives the blade 7 to rotate, so the blade angle can be changed, the airflow cross section can be regulated, and an engine can work at high efficiency at each power section under the support of a pressure booster.
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 dish post.
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 modular construction at the initial stage of improvement is: blade is inserted in the mounting disc, shift fork is welded in blade end, shift fork is enclosed within the drive plate then, overlap an initiatively shift fork on the drive plate again, outer power drives initiatively, and thereby shift fork drives drive plate, and again by the drive plate shift fork, shift fork drives blade rotation, thereby change the cross section of blast tube, drive plate was relaxed with connecting comparatively of inter-module, walk or shortcomings such as blade skids off, blade incoordinate movement under the high temperature.
Summary of the invention
At the deficiency of above-mentioned technology, the driving variable-area nozzle ring member of dish post that reliability is higher, resistance to motion is littler when the utility model proposes high-speed motion under a kind of high temperature.
The technological scheme that the technical problem that the utility model solves is taked is: it is made up of drive plate weldment, shift fork, mounting disc, distance screws, bonnet, blade and drive post, and wherein, blade is contained in the mounting disc, forms the nozzle ring weldment with the shift fork solid welding then; The drive plate weldment directly is enclosed within the mounting disc, is welded with drive post on the drive plate weldment, and drive post is placed directly in the shift fork, between the two 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, the mapping of raising motor, guarantee the technical-economic index and the emission performance of motor.
The utility model has the advantages that: resistance to motion is littler, and transmission is compacter, and the blade action consistency is better, the high temperature reliability of assembly is higher, reduced the relative friction between drive plate and shift fork, required driving force is littler, helps nozzle ring assembly stable operation and improves speed of response.

Fig. 2 is the plan view of Fig. 1
Among the figure 1, nozzle ring weldment 2, drive plate weldment 3, shift fork 4, mounting disc 5, distance screws 6, bonnet 7, blade 8, drive post
Embodiment
In Fig. 1 and Fig. 2: blade 7 is contained in the mounting disc 4, forms nozzle ring weldment 1 with shift fork 3 solid weldings then; Drive plate weldment 2 directly is enclosed within the mounting disc 4, and drive plate weldment 2 can freely rotate; Be welded with drive post 8 on the drive plate weldment 2, drive post 8 is placed directly in the shift fork 3, between the two for being slidingly matched; Bonnet 6 is fixed in the mounting disc 4 by distance screws 5, and so far, bonnet 6, mounting disc 4 and blade 7 have been formed the variable cross section runner.During work, control system is stirred drive plate weldment 2 by an active shift fork, 3 of drive post 8 on the drive plate weldment 2 and shift forks are for being slidingly matched, when therefore drive plate weldment 2 rotates, will drive shift fork 3 rotations by drive post 8,7 rotations of shift fork 3 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.
