Abstract

The utility model provides a waste gas circulation control type turbocharger. A waste gas circulation control mechanism is composed of an upper ring body, a lower ring body, swinging pieces and a driving ring. A swinging handle is formed by extending one side of each swinging piece in an acute included angle. Shaft heads matched with an upper ring body shaft hole and a lower ring body shaft hole in a rotating mode are arranged on the upper end face and the lower end face of each swinging piece, the driving ring is matched with a circumferential guide wheel of the upper ring body in an axial limiting rotating mode, and a groove opening movably embedded into each swinging handle is formed in the ring wall at the position corresponding to the swinging handle of each swinging piece. The turbocharger achieves the aim of one-step assembly and working technology adjustment, simplifies structure, greatly improves assembly efficiency and can ensure assembly accuracy easily.

Description

Waste gas streams flux regulation type turbosupercharger

Technical field

The utility model patent application 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, take engine operation toxic emission air-flow as 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 be made up 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, evenly spaced apart some pendulum compositions of circumferencial direction between lower ring body, 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, the each pendulum reciprocally swinging of synchronous drive, 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 the utility model patent application 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 the utility model patent application 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 composition 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 the utility model patent application, 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, realize and once assembled and coordinate adjustment work, structure not only simplifies the structure, also greatly simplify 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.
