Description
Technical field
The utility model is related to turbocharger apparatus technical field, particularly a kind of combined flow turbine booster.
Background technology
Turbocharger is using the high-temp waste gas of engine discharge, drives the turbine rotation acting in turbine, turbine
Axis drives the impeller high speed rotation in coaxial connected compressor, and compressed air, is supplied to engine high pressure, height in eccentric fashion
Density air.So as to which we can spray more fuel oils to engine, reach and improve engine power, torque and reduction discharge etc.
Purpose.
In the traditional structure of the central rotor assembly of turbocharger, turbine is the most important thing in mechanism, without whirlpool
Wheel cannot drive compressor, that entire turbocharging is gone also just without any effect.Turbine is produced by engine in reject end
Then raw exhaust gas high speed rotation is sucked air, is transported to engine by turbine wheel shaft band dynamic pressure impeller again.In existing market
All it is the radial flow turbocharger used, design and the specific speed run are high, and impeller outlet is caused to arrange in mainstream booster
Gas loss is huge, and impeller internal flow condition is bad so that turbocharger performance drastically deteriorates.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of simple in structure, efficient combined flow turbine superchargings of operation
Device.
In order to solve the above technical problems, combined flow turbine booster provided by the utility model, including volute and turbine wheel shaft
Component, the interior setting runner of volute, the entrance of the runner are made of vertical sidewall and sloped sidewall；Turbine shaft assembly includes fixing
Connected impeller and turbine wheel shaft, the impeller include the blade of the impeller disk and multiple same structures, the center of the impeller disk side with
The turbine wheel shaft is fixedly linked, and blade is placed in the opposite side of the impeller disk, and each blade includes vertical section and inverted sections, and vertical section is vertical
It is connected in the bottom end of the setting of the end face of the impeller disk and vertical section with the impeller disk, the outer side edges of vertical section are outside along the edge of the impeller disk
Setting is stretched out above skew back, the included angle A between the vertical section outer side edges and impeller disk axial direction is 35 °, turbine shaft assembly during assembling
It is placed in volute, the end face of the impeller disk flushes setting with volute vertical sidewall so that the outer side edges of blade vertical section are obliquely installed
In the entrance of runner.
Further, the impeller disk is set in truncated cone-shaped, and the turbine wheel shaft and the center of the small head end side of the impeller disk are fixed
It is connected, the blade is placed in the stub end side of the impeller disk, end face and the volute vertical sidewall of the impeller disk stub end
