Embodiment
Below the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making all other embodiments that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-Fig. 4, the utility model is embodiment comprise:
A kind of changeable flow segmented volute, comprise: housing 1, described housing 1 suction port place is provided with rotary type guide vane 2, and described guide vane 2 drives and is connected with a final controlling element 3, in described housing 1, be provided with two runners that circumference is arranged symmetrically with, be respectively inner flow passage 4 and outer flow passage 5.
Described inner flow passage 4 is along 180 ° of formation of rotor circumference direction rotation, and the starting point of described inner flow passage 4 is the first aditus laryngis 6, and the terminal of inner flow passage 4 is the second aditus laryngis 7 from the first aditus laryngis 6 along 180 ° of rotor circumference direction rotations.
Described outer flow passage 5 be along 360 ° of formation of rotor circumference direction rotation.Outer flow passage 5 comprises two sections: the initial point of first paragraph, terminal are identical with inner flow passage 4, and along 180 ° of rotor circumference direction rotations, the section area of first end is without significant change; Second segment is sprue, and its starting point is the second aditus laryngis 7, and terminal is the first aditus laryngis 6, and along the sense of rotation of first paragraph Rotate 180 ° again, the section area situation of change of second segment is identical with inner flow passage 4.
Described guide vane 2 is located between inner flow passage 4 and outer flow passage 5, and described inner flow passage 4 is open in usual, and described outer flow passage 5 is by guide vane 2 control switchs.Water conservancy diversion presses leaf to carry out water conservancy diversion to entering the waste gas of housing 1, regulates the size of the exhausted air quantity that enters inner flow passage 4 and outer flow passage 5.The runner distance of inner flow passage 4 is shorter, has reduced waste gas and in runner, has expanded the needed time of acting, therefore, when increasing throttle, has improved the acceleration responsiveness of vehicle.
Described final controlling element 3 is pneumatic type final controlling element or electrodynamic type final controlling element.Its major function is exactly after obtaining instruction, makes air inlet guide vane 2 forward preposition to, thereby obtains the object of adjust flux.
Described inner flow passage 4 and outer flow passage 5 all with impeller conducting, waste gas does work by inner flow passage 4 and outer flow passage 5 drives impeller, does not waste resource.
The working procedure of utilizing inner flow passage 4 and outer flow passage 5 to control raising pressurized machine responsiveness when motor accelerates of the present utility model is as follows:
When ato unit, final controlling element 3 makes air inlet guide vane 2 maintain the position of closing, and makes all waste gas all pass through inner flow passage 4.Because the circulation of inner flow passage 4 distance is shorter, therefore the time of setting up energy transmission is also shorter, and the acceleration responsiveness of vehicle is improved, and the outlet pressure of gas compressor also improves rapidly, make the output torque of motor due to more air, can have greatly improved.
When accelerating suddenly, via the adjusting of final controlling element 3, air inlet guide vane 2 is rotated to an angle, suction port cross section is divided into small one and large one two-part, and more waste gas enters inner flow passage 4.As previously mentioned, because the circulation of inner flow passage 4 distance is shorter, the time of therefore setting up energy transmission is also shorter, and the acceleration responsiveness of vehicle is improved.But because " unnecessary " flow still enters impeller via outer flow passage 5, still acting, not waste.
After car speed is improved, air inlet guide vane 2 returns to suction port tangent direction gradually, and the exhaust gas flow that enters inner flow passage 4 and outer flow passage 5 equates gradually.Due to effectively runner increase, make the rotating speed of turbine, when large flow, controlled.
The utility model changeable flow segmented turbocharger housing structure is relatively simple, with less cross section of fluid channel, significantly improves pressurized machine responsiveness when motor accelerates, and can also take into account the demand of large flow aspect, avoids the danger of energy waste and high speed and high pressure.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
