Description
Technical field
This utility model is related to automobile mechanical field, more particularly to a kind of low discharge exhaust-driven turbo-charger exhaust-gas turbo charger.
Background technology
The waste gas of the low discharge exhaust-driven turbo-charger exhaust-gas turbo charger of current automobile from turbine bottom impact turbine leaf, finally from turbine
Middle shaft part is exported, on the one hand, waste gas does not have vertical direction toward impact turbine leaf always, and the kinetic energy conversion ratio of waste gas is not good enough；In addition, waste gas
There is after discharging from electromotor certain heat, and export from the middle shaft part of turbine in exhaust gas centralized, be easily caused the axis mistake of turbine
Heat, affects the service life of turbine.
The content of the invention
The purpose of this utility model is to provide a kind of waste gas kinetic energy high conversion rate, the longer low discharge waste gas of service life
Turbocharger.
To achieve these goals, the technical solution of the utility model is：A kind of low discharge exhaust-driven turbo-charger exhaust-gas turbo charger is provided,
Including Vane wheel, some flabellums and impeller housing, the edge of the Vane wheel is provided with flabellum mounting groove, and the flabellum is in evagination
Indent arc-shaped, the flabellum are uniformly installed in the flabellum mounting groove, and the Vane wheel is installed on the impeller housing
In, the edge of the Vane wheel is connected with impeller housing sealing, forms air channel between the impeller housing and the flabellum,
The impeller housing offers air intake passage and air-out passage, the outer rim phase of the trend of the air intake passage and the Vane wheel
Cut, the outer end of the air intake direction of the air intake passage just to the inner concave of the flabellum, the trend of the air-out passage with it is described
The outer rim of Vane wheel is tangent, the outer end of the air-out direction of the air-out passage just to the arcuate surface of the flabellum.
The air intake passage is orthogonal with the air-out passage.
Compared with prior art, the flabellum of this utility model low discharge exhaust-driven turbo-charger exhaust-gas turbo charger is in evagination indent arc-shaped,
The power of waste gas stream is bigger in institute's lifting surface area of the inner concave of flabellum, while resistance is less suffered by the arcuate surface of flabellum；In addition,
The outer end of the inner concave of waste gas stream vertical direction toward impact flabellum, the moment of torsion suffered by flabellum perform to maximum, so as to substantially increase waste gas
The energy utilization efficiency of stream；In addition, as waste gas is finally exported from outlet passageway, it is to avoid turbine central shaft is overheated, carries
The high service life of turbocharger.
By description below and accompanying drawing is combined, this utility model will become more fully apparent, these accompanying drawings are used to explain this
The embodiment of utility model.
Description of the drawings
Structure charts of the Fig. 1 for the Application Example of this utility model low discharge exhaust-driven turbo-charger exhaust-gas turbo charger.
Fig. 2 is this exploded view using the Application Example of new low discharge exhaust-driven turbo-charger exhaust-gas turbo charger.
Fig. 3 is the local structural graph that this uses new low discharge exhaust-driven turbo-charger exhaust-gas turbo charger.
Specific embodiment
Referring to figs. 1 to Fig. 3, this utility model low discharge exhaust-driven turbo-charger exhaust-gas turbo charger 100 includes Vane wheel 10, some flabellums 20
And impeller housing 30.
The edge of the Vane wheel 10 is provided with flabellum mounting groove 11, and the flabellum 20 is in evagination indent arc-shaped, described
Flabellum 20 is uniformly installed in the flabellum mounting groove 11.The Vane wheel 10 is installed in the impeller housing 30.It is described
The edge of Vane wheel 10 is connected with the sealing of the impeller housing 30.Wind is formed between the impeller housing 30 and the flabellum 20
Road.The impeller housing 30 offers air intake passage 31 and air-out passage 32, the trend of the air intake passage 31 and the flabellum
The outer rim of wheel 10 is tangent, the outer end of the air intake direction of the air intake passage 31 just to the inner concave of the flabellum 20.The air-out
The trend of passage 32 is tangent with the outer rim of the Vane wheel 10, and the air-out direction of the air-out passage 32 is just to the outer of the flabellum
The outer end of convex surface.In the present embodiment, the air intake passage 31 is orthogonal with the air-out passage 32.
This utility model low discharge exhaust-driven turbo-charger exhaust-gas turbo charger 100 is combined operation, air inlet turbine with air inlet turbocharger 200
High pressure draught is input to automobile engine, automobile from extraneous input air after air inlet turbine 210 is pressurized by supercharger 200
The waste gas that electromotor is produced is input to air channel from air intake passage 31, the outer end of the inner concave of waste gas stream vertical direction toward impact flabellum 20, from
And producing moment of torsion rotates Vane wheel 10, and then Vane wheel 10 drives air inlet turbine 210 to rotate by output shaft 300.Due to institute
Flabellum 20 is stated in evagination indent arc-shaped, the power of waste gas stream is bigger in institute's lifting surface area of the inner concave of flabellum 20, while fan
Resistance suffered by the arcuate surface of leaf 20 is less；In addition, the outer end of the inner concave of waste gas stream vertical direction toward impact flabellum 20, suffered by flabellum 20
Moment of torsion performs to maximum, so as to substantially increase the energy utilization efficiency of waste gas stream；In addition, as waste gas is finally from outlet
Passage 32 is exported, it is to avoid turbine central shaft is overheated, improves the service life of turbocharger.
This utility model is described above in association with most preferred embodiment, but this utility model be not limited to it is disclosed above
Embodiment, and modification, the equivalent combinations that the various essence according to the present embodiment are carried out should be covered.
