Description
Technical field
The utility model relates to a kind of engine turbine pressurized machine, particularly a kind of novel blade-rotation variable section turbocharger.
Background technique
Turbosupercharger is that the turbine that the high-temp waste gas that utilizes motor to discharge blows pressurized machine runs up, run up thereby drive with the coaxial compressor impeller of turbine, the pressurized air that compressor impeller produces offers motor again, makes the air inlet of motor become pressure air by natural aspiration.Because the air quantity that provides increases, the motor more fuel that can burn makes burning also more simultaneously, and the turbosupercharger power of consumption of engine not, so turbosupercharger also is exhaust-gas turbocharger.After motor uses turbosupercharger, can improve the power per liter of motor greatly, reduce fuel consumption rate, improve the discharging of motor, turbosupercharger is the new high-tech product of energy-saving and environmental protection.
Present turbosupercharger, it mainly is variable section turbocharger as shown in Figure 1, it comprises turbine box 1, turbine rotor 2, bearing support 3, back of the body dish 4, compressor volute 5, compressor impeller 6, the blade control mechanism, blade 8, shift fork dish 9 and platen 10, between turbine box 1 and bearing support 3, collet 31 is housed, turbine rotor 2 is positioned at the outlet port of turbine box 1, turbine box 1 is installed on the bearing support 3 by bolt, back of the body dish 4 is installed on the bearing support 3 by bolt, compressor volute 5 is installed on the back of the body dish 4 by bolt, compressor impeller 6 is positioned at the outlet port of compressor volute 5, the blade control mechanism comprises rocking arm 71, transmission shaft 72, shift fork 73, supporting disk assembly 74, shift fork 73, supporting disk assembly 74 is connected with rocking arm 71 with transmission shaft 72, blade 8 be positioned at turbine box 1 nozzle position and with being connected of blade control mechanism, shift fork 73, supporting disk assembly 74 is installed on the shift fork dish 9, platen 10 is installed in the outlet port of turbine box 1, transmission shaft 72 is installed on the platen 10, shift fork dish 9 and is installed on the turbine box 1 by platen 10 usefulness bolts between turbine box 1 and platen 10.
Its working principle is, opening angle by adjusting vane 8 changes the airflow area, thereby change the turbine operating mode, reach the purpose that changes the gas compressor boosting capability: during time of engine low speed, control mechanism reduces blade 8 opening angles, thereby reduces circulation area, and secondary speed rises, boost pressure increases, boost pressure when having guaranteed low speed and air inflow; During the high engine speeds running, control mechanism increases blade 8 opening angles, thereby increases circulation area, and secondary speed descends, and prevents the pressurized machine hypervelocity; When motor quickened, for improving speed of response, control mechanism reduced blade 8 opening angles, reduces circulation area, and rotating speed improves, thereby improved boost pressure and air inflow, to satisfy the requirement of transient state air inlet sudden change.
The turbosupercharger in this variable-geometry cross section makes engine performance obtain maximum improvement by the blade angle step-less adjustment, and discharging can be satisfied the needs of the motor of the above discharging of Europe III.Along with country to automobile environment-protection require more and more higher, people like more and more that to power character, Economy, automobile that emission performance is good therefore, the turbosupercharger in variable-geometry cross section is the development trend of turbosupercharger.Its deficiency is:
1, because the blade control mechanism in turbine box 1 and engine exhaust house steward connecting part, when installation dimension changes to some extent, needs engine works' redesign exhaust manifold.
2, since the blade control mechanism near exhaust manifold, but the exhaust manifold temperature is very high, and the reliability of control mechanism is had certain influence.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and provide a kind of setting angle can be in 360 ° of scopes adjustment and bearing support and the existing turbo-charger bearing body novel blade-rotation variable section turbocharger that can exchange arbitrarily, it can also prevent effectively that the blade control mechanism is deflated the damage of house steward's high temperature.
The technical solution of the utility model is: a kind of novel blade-rotation variable section turbocharger, and it comprises turbine box, turbine rotor, bearing support, back of the body dish, compressor volute, compressor impeller, blade control mechanism, blade, shift fork dish and platen; Turbine rotor is positioned at the outlet port of turbine box, and back of the body dish is installed on the bearing support by bolt, and compressor volute is installed on the back of the body dish by bolt; Compressor impeller is positioned at the outlet port of compressor volute; The blade control mechanism comprises rocking arm, transmission shaft, shift fork and supporting disk assembly, and shift fork, supporting disk assembly and transmission shaft are connected with rocking arm; Blade is positioned at turbine box nozzle position and is connected with the blade control mechanism; Platen is installed on the bearing support by bolt, and turbine box is installed on the platen by bolt, and the shift fork dish is installed on the turbine box with bolt between turbine box and platen and by platen; Transmission shaft is installed on the platen, and shift fork, supporting disk assembly are installed on the shift fork dish.
The further technological scheme of the utility model is: collet also is housed between described turbine box and the bearing support.
The utility model compared with prior art has following characteristics:
1, turbine box installation dimension no change, motor producer need not change outlet pipe, has increased the confidence that engine works choose.
2, since the blade control mechanism in the connecting part of turbine box and bearing support, its operating temperature has prolonged the working life of blade control mechanism than many reductions were arranged in the past.Conventional turbocharger is simply reequiped the back just can become novel blade-rotation variable section turbocharger, increased the interchangeability of component, reduced cost, improved benefit.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
