Description
Technical field
Nozzle ring technical field is the utility model is related to, is specially a kind of nozzle ring of good reliability.
Background technology
With the development of technology, requirement of the people for automobile engine is also increasingly harsher, not only to possess powerful
Power, it is necessary to possess the discharge of high efficiency and clean enough.This requires engine will can reach under various operating modes
To its most efficient working status, therefore just it must is fulfilled under each working status of engine for the demand of air inflow.This is just
It is required that each component of engine can meet the condition under different operating modes by " variable ".
Although exhaust energy is considerable when under full engine load state, when the engine speed is lower, energy is vented
Amount is small pitiful, and turbocharger will be unable to reach working speed due to driving force deficiency at this time, so caused by tie
Fruit is exactly, and in the slow-speed of revolution, turbocharger can not play a role, and at this time the power of turbocharged engine shows even
A naturally aspirated engine with discharge capacity can be less than, here it is " the turbo lag that we often say（turbo lag）" phenomenon.
For traditional turbocharged engine, a method for solving turbo lag phenomenon is exactly the lightweight whirlpool using small size
Wheel, first, small turbine can possess less rotary inertia, therefore in low engine speeds, in engine compared with whirlpool under the slow-speed of revolution
Wheel just can reach optimal working speed, so as to be effectively improved the phenomenon of turbo lag.But, also there is lacking for it using small turbine
Point：When the high rotating speed of engine, small turbine can increase exhaust resistance since exhaust section is smaller（Produce exhaust back pressure）, because
This maximum power and peak torque can be affected to some extent.And for producing the less big turbine of back pressure, though
Outstanding supercharging effect can be possessed under right high rotating speed, engine can also possess stronger power performance, but turbine is more under low speed
It is difficult to be driven, therefore turbo lag can also become apparent from.
Existing nozzle ring is complicated, quantity is more, and reliability and durable degree are poor.
Utility model content
The purpose of this utility model is to provide a kind of nozzle ring of good reliability, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the utility model provides following technical solution：A kind of nozzle ring of good reliability, including peace
Sabot, the mounting disc side are provided with shifting disc, and the mounting disc opposite side is provided with rear cover, the rear cover and mounting disc it
Between be provided with spacer sleeve, blade weld assembly is provided with the mounting disc, the tray bottom of stirring is provided with circular arc camber, institute
State mounting disc and be located at shifting disc side and be provided with bulge-structure.
Preferably, the blade weld assembly is made of blade and fork, and blade is installed on shift fork.
Preferably, the mounting disc is arranged to integral type pouring structure.
Compared with prior art, the beneficial effects of the utility model are：Mounting disc one side is fabricated to convex by the utility model
Shape is played, the position of shifting disc can be limited, precision can be used to pour the mode of direct forming, cost substantially reduces；Shifting disc
Bottom be designed to circular arc camber, the contact friction area with mounting disc can be substantially reduced, and reduce the weight of shifting disc；
The mode directly contacted is taken in mounting disc with shifting disc, eliminates the similar complicated part such as roller, can improve whole nozzle
The reliability of ring and reduce cost.
