Abstract
The utility model relates to a machine transmission type variable cross-section turbocharger, especially an exhaust gas turbocharger used for vehicle engine. Besides a snail shell and an impeller, the structure is also provided with a machine transmission type adjusting machine. The power drives a movable plate shaft which controls the size of the cross-section of the snail shell to axially move via the adjusting machine in order to get the required cross-section of the snail shell. The utility model avoids the adjusting disable phenomenon because of clipping and has no gas-leaking problem. Furthermore the utility model has the advantages of simple structure, low cost, being beneficial for batch producing and being easy to install, adjust and maintain, and the variable cross-section turbocharger can be used for the computer to adjust the movement of the movable plate.
Description
The utility model is a kind of turbosupercharger of variable cross section turbine, particularly for motor vehicle exhaust-gas turbocharger.
Disclose a kind of turbosupercharger of variable cross section turbine in US-4499731, its purpose is the mode that embeds removable wall by the spiral case inner chamber, changes the spiral case cross section, improves the matching performance of motor and pressurized machine.Its spiral case cross section is rectangular, and the shifter of its removable wall is to be used as power by the spring that is installed in the spiral case inner chamber, along with the variation of pressure difference value before and after the removable wall, drives removable wall and moves forward and backward.Removable wall and spiral case inner chamber are provided with piston ring, and reduce friction between the two.The amount of movement of removable wall can not adopt microcomputer control in addition, and spring can not be worked under high temperature condition lastingly, so this mechanism is short working life, and it is unreliable to work, and difficulty is installed.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and turbosupercharger that a kind of variable cross section turbine is provided.
The purpose of this utility model can reach by following measure: the variable cross section turbine of this turbosupercharger is except spiral case, impeller are formed, the controlling mechanism of one mechanical transmission-type also is housed in spiral case, comprising trap 6, push rod 7, quill 8, small gear 10 and gearwheel 13.The purpose of this utility model can also reach by following measure: between the inner ring of trap 6 and spiral case inwall ball 4 is housed.Ball 4 is along circumferentially uniform, its axially and fixing of radial position can finish by the collar 5.Controlling mechanism is along the axial location of turbine wheel, by with the fastening end cap 9 of spiral case 3 and baffle ring 14 and fixedly the gear back-up ring 12 of small gear 10 finish jointly.Baffle plate 16 is equipped with at trap 6 tops, and has groove 18 at the corresponding site of right spiral case 3, is beneficial to baffle plate 16 and moves.Spiral case is left and right sides spiral case (1, a 3) structure.
Below in conjunction with accompanying drawing the utility model is further described:
Figure one is turbosupercharger master's sectional view of variable cross section turbine.
Figure two is turbosupercharger left side sectional views of variable cross section turbine.
Figure three is the right sectional views of the turbosupercharger of variable cross section turbine.
Left side spiral case 1 and right spiral case 3 are formed a totally enclosed spiral case, and the spiral case inner chamber is trapezoidal cross-section.The profile of trap 6 is identical with spiral case 1,3 cavity shapes, and it is along radially property distribution in the shape of a spiral of impeller.Trap 6 can be done axial displacement in spiral case 1,3 inner chambers, its power resources are by providing with its fastening push rod that connects 7.One end of push rod 7 is trapezoidal double-screw bolt, and does mutual spiral motion with quill 8.Just doing when actuator provides motivational drive gearwheel 13, when being rotated counterclockwise, drive small gear 10 rotations on quill 8 tail ends, the rotation of small gear 10 has driven the motion of quill 8 and push rod 7 again, thereby realized the front and back axial motion of trap 6, the spiral case cross-sectional sizes can be regulated arbitrarily.Whole controlling mechanism is along the axial location of turbine wheel, be by end cap 9 and the baffle ring 14 fastening with spiral case 3, and fixedly the gear back-up ring 12 of small gear 10 is realized jointly.The air-flow dead band is caused in the space that enters trap 6 back for fear of gas, strengthens the turbine loss, and in spiral case airflow inlet section, a baffle plate 16 has been installed at trap 6 tops, and has groove 18 at the corresponding site of right spiral case 3, is beneficial to baffle plate 16 and moves.In order to reduce the friction of trap 6 and spiral case inner chamber wall, between the inner ring of trap 6 and spiral case inwall, ball 4 is housed, the change sliding friction is rolling friction, has significantly reduced surface friction drag.Also can add suitable graphite oil before the use and further reduce frictional loss, make mechanism's energy proper functioning.Ball 4 is along circumferentially uniform, and it is axial and radial position is fixing by the collar 5.Worm frame is that left spiral case 1 and 3 two parts of right spiral case are processed respectively, is convenient to install, dismantles and maintenance.Because the engine exhaust temperature is higher, thus left spiral case 1 and right spiral case 3 by 15 fastening connections of refractory steel screw, the junction is sealed by copper washer 2.
The utility model has following advantage compared to existing technology: can regulate flexibly and comfortably snail The size in shell cross section has been avoided stuck failure of adjustment phenomenon, does not have the gas leakage problem. Can utilize the amount of movement of microcomputer control trap, simple in structure, cost is low; Be beneficial to batch production, be easy to install, debug and maintenance.
Description of drawings:
The left spiral case of 1-, 2-pad, the right spiral case of 3-, 4-bearing, the 5-collar, 6-trap, the 7-push rod, 8-quill, 9-end cap, 10-pinion, 11-key, 12-gear back-up ring, the 13-gear wheel, 14-baffle ring, 15-heat resisting steel screw, 16-baffle plate, 17-alignment pin, 18-groove.
