Abstract

The patent application of the invention provides a turbocharger with a waste gas flow rate regulation-control function, wherein form composition, a waste gas flow rate regulation-control mechanism comprises an upper ring body, a lower ring body, swing sheets and a drive ring, wherein a swing handle is formed by extending from one side surface of each of the swing sheets at an acute-angle included angle; shaft heads in rotation fit with the shaft holes of the upper ring body and the lower ring body respectively are arranged on the upper end surface and the lower end surface of the swing sheet; the drive ring is in axial limit rotation fit with the peripheral guide wheel of the upper ring body, and a notch for movably embedding the swing handle is correspondingly formed in the ring wall of the drive ring, by being corresponding to the swing handle of each of the swing sheets. Due to the technical scheme, the purposes of one-time assembly and a cooperative adjustment for a working technology are realized, and the structure construction is simplified, thus greatly increasing the assembly efficiency and facilitating a guarantee on the assembly accuracy.

Description

Waste gas streams flux regulation type turbosupercharger

Technical field

Patent application of the present invention relates to motor car engine turbosupercharger, relates in particular to the waste gas streams flux regulation and control part of turbosupercharger.

Background technique

The operation power of exhaust-gas turbocharger stems from motor discharging waste gas, and the engine operation toxic emission air-flow of take is Driving force, drives air intake pressurized work, coordinates air input of engine by air, reaches the effect that improves engine efficiency.Turbosupercharger main-body structure comprises rotor, this rotor is to consist of coaxial turbine and compression impeller, rotor moves through bearing rotary and arranges, turbine and compression impeller are separately positioned in turbine shroud and compression shell, exhaust scroll is arranged in turbine shroud, between turbine radially outer edge and the circumferential air intake of exhaust scroll, is provided with waste gas streams flux regulating and controlling mechanism.Waste gas streams flux regulating and controlling mechanism can be adjusted the valve control device that promotes turbo driving flow according to the different operating conditions of motor, specifically, according to low engine speed or the state that runs up, reduce or extend to the communication port size of exhaust scroll, improve or reduce waste gas flow velocity, improve or reduce rotor speed, reach the compression ratio that increases or reduce air inlet passage, to meet now required air inflow of motor.Waste gas streams flux regulating and controlling mechanism is mainly by upper ring body, lower ring body, control loops and being arranged at, between lower ring body, the even spaced apart some pendulums of circumferencial direction form, together with these parts will be assembled one by one with turbosupercharger associated part, assembling and process debugging operation are very complicated, the rotating shaft of each pendulum is through after upper ring body, again at the axle head suit through upper ring body, be welded and fixed one by one again pendulum handle is set, the pendulum handle outer end activity of each pendulum snaps in and drives in each draw-in groove that pendulum ring inner circumference is corresponding, by driving pendulum ring to drive pendulum handle, synchronous each pendulum reciprocally swinging that drives, in the process swinging, closure or openness flow to the passage of exhaust scroll.After all pendulums and pendulum handle and upper ring body assembling, then will carry out secondary processes assembly operation with lower ring body, the pendulum gap of upper and lower ring body is not easy to adjust, as driven structure between pendulum ring and other parts just to have obvious disconnection technical problem.

In sum, existing product Standard complex operation, assembly precision are difficult to guarantee, high to operation technological requirement, efficiency of assembling is extremely low.

Summary of the invention

The goal of the invention of patent application of the present invention is to provide a kind of welding assembly operation, assembling and precision allotment once completes, precision is high waste gas streams flux regulation type turbosupercharger cancelled.The waste gas streams flux regulation type technology for Turbocharger Manufacturing scheme that patent application of the present invention provides, its main technical content is: a kind of waste gas streams flux regulation type turbosupercharger, wherein waste gas streams flux regulating and controlling mechanism forms and comprises upper ring body, lower ring body, on, pendulum between lower ring body and driving ring, pendulum handle is an acute angle angle by pendulum one side and extends to form, on pendulum, lower end surface is provided with respectively with upper, the spindle nose that lower ring body axis hole is rotatably assorted, described driving ring be with assembling after upper, the driving ring set of lower ring body coaxial line, coordinate to rotation-limited with the circumferential guide wheel shaft of upper ring body, correspondingly with the pendulum handle of each pendulum on its ring wall be provided with the movable notch that embeds pendulum handle.

In above-mentioned overall technical architecture, between upper and lower ring body, be provided with and determine the pendulum setting sleeve of moving working clearance, two ring bodies and setting sleeve are by bolton.

The waste gas streams flux regulation type technology for Turbocharger Manufacturing scheme of patent application of the present invention, the Integral design of pendulum handle and pendulum has been cancelled the assembly operation that is welded and fixed of pendulum handle and pendulum, and make between upper and lower ring body and pendulum and and drive the structure connection between ring set more tight, realized and once assembled and coordinate adjustment work, structure not only simplifies the structure, also greatly simplified assembly and adjustment operation, efficiency of assembling improves greatly, be easy to guarantee assembly precision, after the assembling of waste gas streams flux regulating and controlling mechanism, assemble with turbine shroud again.
