Description
Technical field
The present invention relates to a kind of engine intake duct, relate in particular to a kind of adjustable length air inlet device that is used for motor.
Background technique
At present, existing variable-length suction tude also has the intake manifold length regulated by leaf valve, the employed variable-length suction tude of AUDI_A6 car engine for example, a shared resonant cavity between its length pipe, long tube and short tube two states are arranged, rotate the switching of realization length pipe by the blade that is fixed on the axle with axle, its length pipe is in a plane perpendicular to the section of adjusting axle, therefore the length of long tube is restricted, and the length that it increased is less than the outer circumference of resonant cavity.
Summary of the invention
The present invention provides a kind of spiral air inlet device of variable-length for solving this technical problem that intake manifold length is regulated, and it is big that it not only has the intake manifold length regulation range, and has connection reliably, characteristic of simple structure.
The technical solution adopted for the present invention to solve the technical problems is, a kind of spiral air inlet device of variable-length, it comprises inlet body 1, upper body lid 4, leaf valve 2, the device that resonant cavity 19, short tube outlet 17, long tube outlet 18 and adjusting vane valve open and close, it is characterized in that: inlet body 1 is the spiral volute shape, the setting of staggering mutually between short tube outlet 17 and the long tube outlet 18.
The device that described adjusting vane valve opens and closes is that final controlling element 8 drives the brace and connecting rod framework that axle 7 rotates by rocking arm 11, and axle 7 is installed leaf valve 2 above by nut 10 and tight.
On body, fixedly install limiting stopper 9 and limit the slewing area of rocking arm 11 in regulation, the position that prevents damaged blade valve and overshoot by bolt 13.
For leaf valve 2 is effectively cooperated with the short tube outlet 17 of inlet body, reduce gas leakage, between blade and axle, added certain thickness leaf valve cushion block 5.Simultaneously axle is gone up for stator blade, processes a plane in that leaf valve 2 sides are installed, and is drilled with tapped hole on the axle, and leaf valve 2, leaf valve cushion block 5 and axle 7 are tightened by thread screw 6, and screw adopts backing-up screw.
The axial float that locating stud 14 comes restrictive axes 7 also is set on axle 7, two round section joint rings 12 is set comes gap between seal shaft and the suction tude upper body.
For making spirally inlet air body 1 and upper body cover 4 good seals, inlet body Cover Gasket sheet 3 is set.
Working principle of the present invention is, final controlling element 8 rotating band moving axis 7 rotate, drive is contained in the rotating opening of the leaf valve 2 on the axle and closes short tube outlet 17, when closing short tube when exporting 17, gas in the resonant cavity 19 can only from long tube export 18 through long tube passage 15 paths to motor, be long tube state; When short tube outlet 17 is opened fully, and the passage between the long tube outlet 18 is by short circuit, the gas in the resonant cavity 19 directly from short tube outlet 17 through short tube passage 16 paths to motor, be short tube state.
Good effect of the present invention is, because inlet body is the spiral volute shape, its length pipe is not in a plane perpendicular to the section of adjusting axle, therefore, the pipe range that the long tube state is increased is the periphery of spiral around resonant cavity, pipe range can be very long, characteristics with compact structure, remedied the shortcoming that conventional variable length suction tude long tube length is short and spatial arrangement is nervous, length tubulose attitude is switched simple simultaneously, can there be long tube short tube two states to switch, be suitable for to carry out the conversion of length pipe and the very compact motor in space.
