The utility model reaches the goal of changing free section of turbines by changing the angle of the nozzle ring blades, and thus, matching performance of the turbosupercharger and the engines is improved. The utility model and an actuator are a whole body. The utility model has the advantages of compact structure, reliability, stable and compliant change of free section of turbines, small loss of flow resistance, high turbine efficiency, and low cost.

Description

Mixed flow blade-rotation variable-area turbocharger
The utility model is a kind of mixed flow blade-rotation variable-area turbocharger, and it mainly is suitable for the motor on the automobile, engineering machinery, special vehicle of requirement low-speed big, belongs to technical field of engines.
The turbocharging technology of internal-combustion engine can make engine performance be significantly improved.Therefore turbosupercharging not only be used for marine engine, locomotive with internal-combustion engine, transportation formula vehicle with internal-combustion engine, stationary power generation unit with internal-combustion engine, also be used for the various internal-combustion engines in each field of national economy.But turbocharging technology is used to transport formula vehicle internal combustion engine field than later, up to early sixties since radial-flow type small sized turbine pressurized machine succeed in developing and commercialization just developed rapidly, its main cause is that the characteristics of vehicle internal combustion engine require the turbosupercharger size little, reliable in structure, good aeroperformance, can satisfy road and load variations condition extremely complicated in the vehicle driving, and low price etc.In recent years, because haulage vehicle is with the performance improvement of supercharged diesel engine, the increasing substantially of mean effective pressure, thereby ubiquity the low speed torque deficiency, the acceleration extreme difference quickens to smolder, defectives such as cold starting difficulty.The appearance of these problems is different with the working method of pressurized machine mainly due to diesel engine, and the two is difficult to good coupling.Solve these problems targetedly, obtain a kind ofly should the low speed torque performance well requiring the high-speed working condition condition that the good power character and the vehicle power of fuel economy are arranged again, it be the most suitable selecting the variable cross section turbo-charged diesel.
The purpose of this utility model is to provide a kind of turbosupercharger of efficient, reliable, practical novel changable cross section turbine.It has overcome the turbosupercharger that in the past adopts variable geometry turbocharger owing to reasons such as air-flow path shape sudden change gas dams cause turbine efficiency to be lower than conventional defectives such as turbosupercharger, make supercharged diesel engine when low speed, obtain higher boost pressure, keep supercharged diesel engine that good low speed torque performance is arranged, the acceleration of reasonable solution supercharged diesel engine problem such as smolder.On structural configuration, can be accepted by Vehicle Turbocharged diesel engine user on the performance simultaneously.
The utility model is the target that realizes mixed flow blade-rotation variable cross section by following measure: this turbosupercharger is made up of spiral case, rotatable nozzle blade, turbine wheel and rotation controlling mechanism; Rotate controlling mechanism and be arranged on the end of intermediate by turbine, comprising: blade installation dish, drive plate, passive fish tail fork, passive fish tail jaw, active fish tail fork, active fish tail jaw, installing and locating supporting ring, power transmission shaft, transmission shaft Sealing, final controlling element link arm; The passive fish tail fork of nozzle blade and drive blade rotation angle connects; Initiatively one of fish tail jaw is contained in the active fish tail fork, and one is contained in the drive plate, and one of passive fish tail jaw is contained in the drive plate, and one is contained in the passive fish tail fork; The installing and locating supporting ring is housed between pressurized machine intermediate and drive plate; Between power transmission shaft and intermediate, Sealing is housed; Blade installation dish side is an arc step surface, and the blade installation dish compresses mutually by volute and intermediate and is installed on the intermediate.
The utlity model has following advantage: it has kept mixed flow or the high intrinsic advantage of radial-flow turbine booster turbine efficient, has mixed flow and radial-flow turbine pressurized machine can solve supercharged diesel engine low-speed big, instant getaway difference and acceleration specific question such as smolder again.And at serviceability of structures, there are many novel characteristics aspects such as manufacture cost.It obviously is better than with bleed valve adjustable mixed flow and radial-flow turbine pressurized machine.
