Abstract

The utility model discloses a compact disk shaped driving variable cross section nozzle ring component with more compact driving, better blade action consistency, and higher high temperature reliability of components. The compact disk shaped driving variable cross section nozzle ring component comprises a blade 4, an installation disk 5, a driving disk 6, a shifting fork 7, a lantern ring 9, a driving plate 10 and a driving post 11, wherein the blade 4 is installed in the installation disk 5 and is fixedly welded with the shifting fork 7 to form a nozzle ring welding component 13 together, the driving disk 6 is directly sleeved on the installation disk 5, the driving post 11 is inserted into the driving plate 10, and a lantern ring 9 is welded on the driving post 11. When in work, the lantern ring 9 and the driving post 11 are dialed, thereby driving the driving plate 10 and the driving disk 6, the driving disk 6 and the shifting fork 7 form sliding fit, thereby when the driving disk 6 is rotated, the shifting fork 7 is driven to rotate, the shifting fork 7 drives the blade 4 to rotate, thereby changing the blade angle and adjusting the gas flow cross section, and engines can work more effectively on each power section under the support of a supercharger.

Description

Compact dish type drives the variable-area nozzle ring member
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 the variable-area nozzle ring member.
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.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, regulate flow area by the drive plate driven rotary, make the motor can both more efficient ground work (number of patent application: 200610163404.8) in each power section under the support of pressurized machine.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, shift fork drives drive plate thereby outer power drives initiatively, by the drive plate shift fork, shift fork drives blade rotation again, thereby changes 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, it is compacter to the utility model proposes a kind of transmission, and the blade action consistency is better, and the compact dish type that the high temperature reliability of assembly is higher drives the variable-area nozzle ring member.
The technological scheme that the technical problem that the utility model solves is taked is: described nozzle ring assembly comprises distance bolt, nut, bonnet, blade, mounting disc, drive plate, shift fork, pad, the collar, driving plate, drive post and screw, wherein, blade is contained in the mounting disc, forms the nozzle ring weldment jointly with the shift fork solid welding; Drive plate directly is enclosed within the mounting disc, and after blade and shift fork solid welding, the position of drive plate is fixed in weldment; Bonnet is fixed in the mounting disc by distance bolt and nut, and so far, bonnet, mounting disc and blade have been formed the variable cross section runner; Pad and driving plate by screw on drive plate; Drive post is inserted in the driving plate, and the collar is welded on the drive post.
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.
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, distance bolt 2, nut 3, bonnet 4, blade 5, mounting disc 6, drive plate 7, shift fork 8, pad 9, the collar 10, driving plate 11, drive post 12, screw 13, nozzle ring weldment
Embodiment
In Fig. 1 and Fig. 2: blade 4 is contained in the mounting disc 5, forms nozzle ring weldment 13 jointly with shift fork 7 solid weldings; Drive plate 6 directly is enclosed within the mounting disc 5, and after blade 4 and shift fork 7 solid weldings, the position of drive plate 6 is fixed in weldment; Bonnet 3 is fixed in the mounting disc 5 by distance bolt 1 and nut 2, and so far, bonnet 3, mounting disc 5 and blade 4 have been formed the variable cross section runner; Pad 8 and driving plate 10 are fixed on the drive plate 6 by screw 12; Drive post 11 is inserted in the driving plate 10, and the collar 9 is welded on the drive post 11.During work, engine control system is stirred the collar 9 and drive post 11 simultaneously by an active shift fork, thereby drive driving plate 10 and drive plate 6,7 of drive plate 6 and shift forks are for being slidingly matched, when therefore drive plate 6 rotates, will drive shift fork 7 rotations, shift fork 7 drives blades 4 rotations, thereby change angle, the adjusting flow area of blade 4, motor can both be worked on more efficient ground in each power section under the support of pressurized machine.
