Description

The turbosupercharger of double-leaf nozzle system
Technical field
The utility model relates to the turbosupercharger of double-leaf nozzle system, belongs to the automotive fittings field.
Background technique
Waste gas by motor is discharged is the turbine work done in the pressurized machine, can only be in work in the narrow and small efficient district.Even be placed on the vehicle supercharger design point in the 50-70% scope, then motor must cause the pressurized machine hypervelocity at full capacity the time.People are added in exhaust by-pass valve mechanism on the pressurized machine for this reason, to improve its reliability, have also wasted the energy of the available combustion gas of part simultaneously.
Adopting the adjustable nozzle structure is to improve the effective ways of turbine pneumatic performance, also is the enforcement that each pressurized machine manufacturer of the world generally acknowledges and pays, and three kinds of different schemes are arranged at present:
By U.S. Honeywell Int Inc patent applied for number 200710152744.5 " blade assembly of variable nozzle turbocharger and the assembling methods of blade assembly " is exactly the variable-nozzle method that adopts the rotor blade angle.To be the cross-section area of nozzle reduce with the minimizing of blade rotating angle its advantage, and the nozzle area slip can reach more than 50%; Shortcoming is nozzle angle α excessive (a starting state), air-flow C, and " r clashes into turbine leaf convex surface; Spray angle α too small (completely negative state), air-flow C ' r clashes into leaf concave surface (seeing Figure 11), and pressurized machine thermal efficiency when low high operating mode is worked is descended.
Variable cross section by the French Honeywell Garrett Co., Ltd number of applying for a patent 00819834.9 " the form-varied turbosupercharger that has sliding piston " is simple in structure, and nozzle is half the by stator blade, and second half is made up of no leaf air flue.Adjustable area only has or not the leaf air flue, and this is half the, and certain adjustable area 50% has been enough, but its aeroperformance is bad.When no leaf passage is opened, air-flow will flow through from blade path and no leaf passage simultaneously, because the flow angle of two passages is inequality, the air turbulence with causing behind the nozzle increases the air current flow loss, reduction turbine heat efficient.
By the variable-nozzle structure that the special energetics of Britain's Hall plug Co., Ltd puts forward, on the fixed nozzle blade, to adorn a screen and close circle, mobile screen closes circle can cover the portion nozzle runner, reaches the purpose in adjustable nozzle cross section.Its shortcoming covers the portion nozzle runner and must cause from the air turbulence of volute to nozzle inlet as alternative plan, can reduce turbine heat efficient equally.
The model utility content
The technical problem that the utility model will solve is to overcome existing defective, and the turbosupercharger of double-leaf nozzle system is provided.Along new blade is set in the nozzle flow channel, can reduce channel cross-sectional area, be separated into two air flues to former nozzle again, to reduce the loss of air-flow lateral flow.Air-flow is still moving by intrinsic best air-flow angular flux simultaneously, can keep turbine in efficient district's work.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
The turbosupercharger of double-leaf nozzle system comprises turbine casing, fixed nozzle ring, straight line moving nozzle dish, mesochite, tooth bar, rocking lever, gear; Said fixed nozzle ring front-end face has one group of stator blade, and it is shaped as airfoil, has the leaf type hole between the stator blade; In the middle of the fixed nozzle ring center hole is arranged, be sleeved on the mesochite outer ring, and pass through screw on mesochite; Fixed nozzle ring rear end is equipped with straight line moving nozzle dish, and straight line moving nozzle dish front-end face has one group of moving blade, and the shape of moving blade is consistent with the shape in leaf type hole; Moving blade is inserted in the leaf type hole versatilely, in the middle of the straight line moving nozzle dish center hole is arranged, and is sleeved on the mesochite outer ring; Straight line moving nozzle back-end disk face is fixedly connected with two rocking levers, and rocking lever inserts in the mesochite, and the rocking lever end has tooth; Be meshed with a tooth bar through gear, tooth bar is connected with drive unit.
Further, the flow inlet angle scope of said blade is 18-24 °.
Further, stator blade quantity is 4-11, and moving blade quantity is 4-11.
Further, the drive unit of connection tooth bar is gas bag final controlling element or solenoid valve.
The turbosupercharger of the utility model double-leaf nozzle system can reduce channel cross-sectional area along new blade is set in the nozzle flow channel, is separated into two air flues to former nozzle again, to reduce the loss of air-flow lateral flow.Air-flow is still moving by intrinsic best air-flow angular flux simultaneously, can keep turbine in efficient district's work.Moving blade and stator blade are equidirectional along air-flow, can avoid as alternative plan and third party's case, causing air turbulence, reduce flow resistance loss.Through the increase or the minimizing of adjustment blade quantity, reach the purpose of regulation and control exit area of nozzle.When moving blade all gets in the stator blade, the long-pending slip of its cross section of fluid channel can be adjusted with wing thickness, can satisfy the needs of motor variable working condition.Its vane thickness of different turbosupercharger is different, to adapt to actual demand.
