Description
Technical field
The utility model is related to vehicle engine booster technical field, and in particular to a kind of nozzle ring capable of changing cross sections.
Background technology
It is general to use after fork and blade welding and riveting currently used for the nozzle ring capable of changing cross sections of exhaust gas turbocharge,
Fork disc spins outside fork rotate to an angle come driving blade group, are all separated between existing fork disk and fork
Structure, is not attached to together, drives fork to rotate by various forms of cooperations between fork disk and fork and relative motion,
So as to drive blade group to rotate to required angle, its structure as shown in figure 1, including mounting disc 1a, shifting fork disc 2a, blade group and
The axis hole 5a for being used for installing blade 3a, institute are provided with blade 3a quantity identical the shift forks 4a, the mounting disc 1a of blade group
State and be provided with that sharf 6a, one end of the sharf 6a and blade 3a are affixed in axis hole 5a, one end of the other end and shift fork 4a
Affixed, the other end and the shifting fork disc 2a of the shift fork 4a are slidably connected, and shifting fork disc 2a rotations can drive shift fork 4a to rotate, and dial
4a rotating band movable vane pieces 3a rotations are pitched, so as to change blade 3a angle to adjust flow area.
But existing nozzle ring capable of changing cross sections still has following technical problem：1st, because fork disk 2a and fork 4a are
Isolating construction, fork disk 2a with relative motion is merged by driving fork 4a to rotate, in use, easily at both
Between produce abrasion, so as to cause fit clearance constantly to increase, greatly reduce the precision and reliability of product, or even cause card
Extremely；2nd, by being driven with relative motion is merged between fork disk 2a and fork 4a, the gap of cooperation determines the precision phase of product
To relatively low；3rd, fork disk 2a is with fork 4a with relative motion is merged, and produced driving force is smaller, in the engine of larger displacement
Exhaust impact under failure easy to wear or can not drive, therefore cannot be used for the supporting turbocharger of larger displacement engine
In.
Utility model content
The technical problems to be solved in the utility model is：There is provided a kind of fork disk to link into an integrated entity with fork, precision and can
It is higher by property, and it is applicable to the nozzle ring capable of changing cross sections of the exhaust gas turbocharge of huge discharge.
Technical solution of the present utility model is：A kind of nozzle ring capable of changing cross sections, including mounting disc, shifting fork disc, blade
Group and the shift fork equal with the blade quantity of blade group, one end of the shift fork passes through the sharf in mounting disc axis hole
It is connected with blade, it is characterised in that：Connection sheet, one end of the connection sheet are provided between the other end and shifting fork disc of the shift fork
It is hinged with the other end of shift fork, the other end is hinged with shifting fork disc.
After said structure, the utility model has advantages below：
The utility model nozzle ring capable of changing cross sections sets one end of connection sheet and the other end of shift fork to be hinged, the other end with
Shifting fork disc is hinged, and connection sheet is formd double link structure with shift fork, fork disk links into an integrated entity with fork；This one
The structure of body formula compares traditional isolating construction, increases in the absence of the gap brought with occlusal wear, and transmission accuracy is higher, blade rotation
More preferably, service behaviour is more excellent for the angle agreement turned；Fork disk drives blade speed ratio divergence type knot using double link structure
Structure reliable operation, the possibility broken down is smaller, and service life is higher；Fork disk drives blade rotation using double link structure
Make torque bigger, be applicable to the exhaust gas turbocharge of more huge discharge.
Preferably, one end of the connection sheet is hinged in the first mounting hole of the shift fork other end by first axle, separately
One end is hinged in the second mounting hole of shifting fork disc by the second axle.The setting makes connection sheet and the double link structure of shift fork formation
Simply, connect reliable, rotate flexible.

Embodiment
Below in conjunction with the accompanying drawings, and in conjunction with the embodiments the utility model is described further.
Embodiment：
As shown in Fig. 2 a kind of nozzle ring capable of changing cross sections, including mounting disc 1, shifting fork disc 2, blade group and the leaf with blade group
The equal shift fork 4 of the quantity of piece 3, the present embodiment sets the quantity of blade to be 12, and one end of the shift fork 4 passes through installed in installation
Sharf 6 in the axis hole 5 of disk 1 is connected with blade 3, it is characterised in that：It is provided between the other end and shifting fork disc 2 of the shift fork 4
