Abstract
The invention discloses a variable-section nozzle assembly for a turbocharger. The assembly comprises a fixed ring and an adjusting ring; the fixed ring is fixed in a turbine shell; the adjusting ring rotationally sleeves the fixed ring, and is provided with multiple adjusting holes; multiple through holes are formed in the fixed ring corresponding to the adjusting holes; the adjusting holes and the through holes are concentrically arranged when aligned; and the adjusting ring is connected with a shifting fork for shifting the adjusting ring to rotate. According to the variable-section nozzle assembly for the turbocharger, the adjusting ring is rotated through the shifting fork, and the adjusting holes and the matched through holes on the fixed ring are staggered, so that the through-flow area is reduced to achieve the purpose of variable sections. The assembly is simple in structure and convenient to assemble; and the occupied installation space is small, thus materials for volute can be saved, the cost is reduced, materials for a middle shell are increased, thereby adding a water cooling cavity to enhance the heat dissipation effect of the supercharger, and the operation is more reliable and stable.
Description
Technical field
The present invention relates to a kind of turbocharger, especially relate to a kind of variable cross section for turbocharger
Nozzle assembly.
Background technology
A kind of air compressor of turbocharger, increases air inflow by compressed air.It is
Utilizing waste gas inertia impulsive force that electromotor discharges to promote the turbine in turbine room, turbine drives again coaxial leaf
Wheel, the air that impeller force feed is sent here by air filter pipeline, it is allowed to supercharging and enters cylinder.When electromotor turns
Speed increases, and the waste gas velocity of discharge is the most synchronize with secondary speed to be increased, and impeller just compresses more air and enters gas
Cylinder, the pressure of air and density increase the more fuel that can burn, and corresponding increase fuel quantity and adjustment are started
The rotating speed of machine, it is possible to increase the output of electromotor.
The turbocharger of variable cross section is compared with conventional turbocharger, when significantly improving the slow-speed of revolution
Response time and acceleration capacity.Use the petrol engine of variable turbine cross section technology in all ranges of speeds
Efficiency obviously higher than current accepted standard venting valve type turbocharger.Correspondingly, at each turn
Fuel saving in the range of speed also attains a yet higher goal.
At present, it is complicated generally to there is structure in the nozzle assembly of the turbocharger of existing variable cross section, needs
A lot of special toolings complete assembling and weld the shortcoming bringing more fault and damage with number of parts more.
Summary of the invention
It is an object of the invention to provide a kind of variable-area nozzle assembly for turbocharger, it has
Simple in construction, it is easy to assembling, volume is little and reliability is high feature, to solve in prior art for turbine
The problems referred to above that the variable-area nozzle assembly of supercharger exists.
For reaching this purpose, the present invention by the following technical solutions:
A kind of variable-area nozzle assembly for turbocharger, it includes retainer ring and regulation ring, described
Retainer ring is fixed in turbine case, and described regulation ring is placed on outside described retainer ring rotationally, wherein, and institute
Stating and offer several adjustment holes on regulation ring, corresponding described adjustment hole offers some in described retainer ring
Individual through hole, is arranged concentrically when described adjustment hole and described through-hole alignment, and described regulation ring is connected to stir
Its shift fork rotated.
Especially, described adjustment hole is distributed on described regulation ring, and described through hole is distributed in described retainer ring.
Especially, described adjustment hole and described through hole are in tilted layout, and both incline directions coordinate turbine case
Airintake direction is arranged.
Especially, a support component it is provided with between described retainer ring and described regulation ring.
Especially, described support component includes several support shafts being fixed on described retainer ring side, described
Support shaft is outside equipped with support wheel, and the inwall of described regulation ring contacts with the described wheel that supports.
Especially, described retainer ring offering several fixing holes, fixing screw will through described fixing hole
Retainer ring is fixed in turbine case.
Beneficial effects of the present invention is, compared with prior art the described variable cross section spray for turbocharger
Nozzle assembly makes the rotation of regulation ring by shift fork, and the through hole that adjustment hole coordinates with retainer ring forms offset pattern,
To reduce flow area, thus reach the purpose of variable cross section.It is not only simple in structure, it is simple to assembling；And
The installing space taken is little, so can save volute material, reduces cost, makes middle case material simultaneously
Increase, thus increase waterway to strengthen supercharger radiating effect, run relatively reliable stable.
