Embodiment
Embodiment 1 as shown in Figure 2 to Figure 3, the turbocharging system with changeable flow sectional type volute of the present embodiment
System includes a sectional volute with variable flow, and the sectional volute with variable flow includes：Being provided with housing 1, the air inlet of housing 1 can
Two streams being arranged symmetrically in rotary guide vane 2, the drive connection of 2 and one actuator of guide vane 3, housing 1 provided with circumference
Road, respectively inner flow passage 4 and outer flow passage 5.Diversion component, the diversion component are set at the sectional volute with variable flow air inlet
Gas outlet at be fixedly installed shunting guide plate 81, the tangent line of the shunting guide plate 81 along sectional volute with variable flow air inlet
Direction is set, so that air inlet guide vane 2 is arranged on same straight line with shunting guide plate 81 when air inlet guide vane 2 is opened completely
On, air inlet guide vane 2 to the inwall direction of housing 1 rotate when, air inlet guide vane 2 and shunting guide plate 81 between Formation cross-section
The variable slanted channel 84 of product；First flow-guiding channel 82, the second flow-guiding channel 83, the first flow-guiding channel are set in diversion component
82nd, the import of the second flow-guiding channel 83 is communicated with engine exhaust port（For the engine with multiple exhaust outlets, the first water conservancy diversion
Passage 82, the second flow-guiding channel 83 can respectively be communicated from different engine exhaust ports；For only having starting for exhaust outlet
Machine, the first flow-guiding channel 82, the second flow-guiding channel 83 are communicated with same exhaust outlet so that the waste gas of exhaust outlet discharge can be through first
Flow-guiding channel 82, the second flow-guiding channel 83 carry out water conservancy diversion）, the outlet of the first flow-guiding channel 82 is arranged on the one of shunting guide plate 81
Side, and the outlet of the first flow-guiding channel 82 communicates with outer flow passage 5；The outlet of second flow-guiding channel 83 is arranged on shunting guide plate 81
Relative opposite side, and the outlet of the second flow-guiding channel 83 communicates with inner flow passage 4, during so that air inlet guide vane 2 being opened completely,
Outer flow passage 5, stream can be entered along the tangential direction of sectional volute with variable flow air inlet by flowing through the waste gas of the first flow-guiding channel 82
Waste gas through the second flow-guiding channel 83 can enter inner flow passage 4 along the tangential direction of sectional volute with variable flow air inlet, improve
The circulation efficiency of waste gas.
Inner flow passage 4 is to rotate 180 ° of formation along rotor circumference direction, and the starting point of inner flow passage 4 is the first aditus laryngis 6, interior stream
The terminal in road 4 is that 180 ° of the second aditus laryngis 7 is rotated from the first aditus laryngis 6 along rotor circumference direction.Guide vane 2 is located at inner flow passage 4
Between outer flow passage 5, inner flow passage 4 is open in usual, and outer flow passage 5 passes through the controlling switch of guide vane 2.2 pairs of guide vane enters shell
The waste gas of body 1 carries out water conservancy diversion, and regulation enters the size of the exhausted air quantity of inner flow passage 4 and outer flow passage 5.The runner distance of inner flow passage 4 compared with
It is short, time of the waste gas in runner required for expansion work is reduced, therefore when increasing throttle, the acceleration for improving vehicle rings
Ying Xing.Actuator 3 is pneumatic type actuator or electrodynamic type actuator.Its major function is exactly after instruction is obtained, to make air inlet
Guide vane 2 goes to predetermined position, so as to obtain the purpose of regulation flow.
The course of work of turbo charge system of the present utility model with changeable flow sectional type volute is as follows：Starting
During engine, actuator 3 makes air inlet guide vane 2 maintain the position of closing, and the waste gas for flowing through the second flow-guiding channel 83 is straight
Connect along the tangential direction of sectional volute with variable flow air inlet and enter inner flow passage 4, flow through the waste gas edge of the first flow-guiding channel 82
Slanted channel 84 between air inlet guide vane 2 and shunting guide plate 81 fully enters inner flow passage 4, because the circulation of inner flow passage 4
Distance is shorter, therefore sets up that the time of energy transmission is also shorter, and the acceleration responsiveness of vehicle is improved, and compressor
Outlet pressure is also improved rapidly, is made the output torque of engine due to more air, can be had greatly improved.
In unexpected accelerate, via the regulation of actuator 3, air inlet guide vane 2 is set to rotate to an angle, air inlet water conservancy diversion leaf
There is gap between piece 2 and inner walls, while being similarly formed slanted channel between air inlet guide vane 2 and shunting guide plate 81
84, the waste gas for flowing through the second flow-guiding channel 83 directly enters inner flow passage along the tangential direction of sectional volute with variable flow air inlet
4, the waste gas for flowing through the first flow-guiding channel 82 enters along the part of slanted channel 84 between air inlet guide vane 2 and shunting guide plate 81
Enter inner flow passage 4, flow through the waste gas of the first flow-guiding channel 82 along air inlet guide vane 2 and shunt the slanted channel between guide plate 81
84 parts enter outer flow passage 5 through the gap between air inlet guide vane 2 and inner walls, so that more waste gas enters inner flow passage
4.As mentioned previously, because the circulation distance of inner flow passage 4 is shorter, therefore set up that the time of energy transmission is also shorter, vehicle plus
Fast response is improved.But it is due to that " unnecessary " flow still enters impeller via outer flow passage 5, still does work, without wave
Take.
After car speed is improved, air inlet guide vane 2 is gradually brought to air inlet tangential direction, air inlet water conservancy diversion leaf
Slanted channel 84 between piece 2 and shunting guide plate 81 is closed, and flows through the waste gas of the first flow-guiding channel 82 all along changeable flow
The tangential direction of segmented volute inlet enters outer flow passage 5, flows through the waste gas of the second flow-guiding channel 83 all along changeable flow
The tangential direction of segmented volute inlet enters inner flow passage 4, improves the circulation efficiency of waste gas so that the rotating speed of turbine,
It is controlled during big flow.
Obviously, above-described embodiment is only intended to clearly illustrate the utility model example, and is not to this reality
With the restriction of new embodiment.For those of ordinary skill in the field, may be used also on the basis of the above description
To make other changes in different forms.There is no necessity and possibility to exhaust all the enbodiments.And these
Belong to obvious change or change still in protection domain of the present utility model that spirit of the present utility model amplifies out
Among.
