, there is exhaust gas by-pass valve volute technology in the problem that while turning round for solving high engine speeds, supercharging is excessive, blade flies to split.But it still can not solve the problem of low speed supercharging deficiency completely, if this is that motor, when the operating mode of high speed high load, will cause a large amount of waste gas just directly to discharge without any utilization so because really want so, its energy containing is not utilized effectively, and has formed energy dissipation.
For meeting the performance requirement of motor in full condition range, people have successfully developed variable geometry turbine technology, can take into account demand low, at a high speed.But its complex structure, processing technology difficulty is high, and assembling difficulty is large, expensive, and also harsher to the condition of using, and maintenance cost is high.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of triple channel volute of variable cross section, problem that can turbocharger low speed boost performance is poor He high-speed boosting is excessive, blade flies to split.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: the triple channel volute that a kind of variable cross section is provided, comprise: housing, in described housing, be provided with at least three exhaust steam passages, corresponding three exhaust steam passages of suction port end of described housing are provided with two rotary type tongue pieces, two tongue pieces are connected with two transmission shafts respectively, and each transmission shaft one end all extends to outside housing through housing, and are connected with two cranks respectively.
In a preferred embodiment of the present invention, described three exhaust steam passages are respectively first passage, second channel and third channel, two rotary type tongue pieces are respectively the first tongue piece and the second tongue piece, described the first tongue piece is located between first passage and second channel, and described the second tongue piece is located between second channel and third channel.
In a preferred embodiment of the present invention, described second channel is normal open walk.
In a preferred embodiment of the present invention, the sense of rotation of described the first tongue piece is to rotate towards first passage from suction port tangent direction, and the sense of rotation of the second tongue piece is to rotate towards third channel from the tangent direction of suction port.
In a preferred embodiment of the present invention, the angle of swing of described the first tongue piece and the second tongue piece is less than or equal to 90 °.
In a preferred embodiment of the present invention, described two tongue pieces are connected with transmission shaft by two keys respectively.
In a preferred embodiment of the present invention, between described transmission shaft and housing, be provided with lining.
The invention has the beneficial effects as follows: the triple channel turbocharger housing structure control mechanism simple, the relatively general variable-geometry of rotatable parts of variable cross section of the present invention is reliable, and can significantly improve the supercharging intensity of pressurized machine when low engine speed is moved, improve low engine speed moment of torsion, the problem that in the time of can effectively avoiding again high engine speeds running simultaneously, supercharging is excessive, blade flies to split.

Embodiment
Below the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1-Fig. 5, the embodiment of the present invention comprises:
A triple channel volute for variable cross section, comprising: housing 1, in described housing 1, be provided with at least three exhaust steam passages, and corresponding three exhaust steam passages of suction port 11 ends of described housing 1 are provided with two rotary type tongue pieces.
Two tongue pieces are connected with two transmission shafts 7 by two keys 9 respectively, and each transmission shaft 7 one end all extend to outside housing 1 through housing 1 by lining 10, and are connected with two cranks 8 respectively.
Wherein, three exhaust steam passages of the preferred embodiments of the present invention are respectively first passage 2, second channel 3 and third channel 4, two rotary type tongue pieces are respectively the first tongue piece 5 and the second tongue piece 6, described the first tongue piece 5 is located between first passage 2 and second channel 3, and described the second tongue piece 6 is located between second channel 3 and third channel 4.Described second channel 3 is normal open walk.
