The invention relates to a turbocharger turbine capable of achieving adaptive adjustment of nozzle ring guide vanes. The turbocharger turbine comprises a turbine body, an air compressor, an intermediate and a guide vane adaptive adjustment device. The guide vane adaptive adjustment device comprises a supporting plate, the multiple guide vanes, a plurality of rocker arms, a plurality of rotary shafts and a plurality of elastic rods, wherein the supporting plate is installed outside an impeller of the turbine in a surrounding mode, and a through hole is formed in the middle of the supporting plate; the multiple guide vanes are installed on the outer side face of the supporting plate and arranged circularly; the rocker arms are evenly distributed on the inner side of the supporting plate circularly; one end of each rotary shaft is manufactured integrally with the corresponding guide vane, and the other end of each rotary shaft rotationally penetrates through the supporting plate to be fixedly connected with one end of the corresponding rocker arm; and the two ends of each elastic rod are connected with the other ends of the two rocker arms adjacent to the former elastic rod separately. According to the turbocharger turbine capable of achieving adaptive adjustment of the nozzle ring guide vanes, active control of an ECU over the guide vanes through an actuating mechanism is omitted, structural complexity is avoided, and meanwhile the production cost is greatly reduced; and the opening degree of the guide vanes can be adjusted in an adaptive mode according to the flow.
Description
technical field [0001] The invention belongs to the field of auto parts, in particular to a nozzle ring guide vane self-adaptive regulation supercharger turbine. Background technique [0002] With the improvement of emission standards and energy saving and emission reduction requirements, turbocharger regulation technology has almost become a standard configuration to meet higher requirements. Due to the existence of the rotor inertia of the turbocharged internal combustion engine, there will be acceleration hysteresis during the acceleration process, and it will even cause smoke during acceleration and affect emissions. [0003] At present, the variable geometry supercharger (VGT) can increase the energy supply of the turbine by adjusting the flow section of the turbine during the acceleration process, improve the acceleration of the rotor, and then solve the problem of acceleration hysteresis. It is an important measure of economy, and the low-speed working condition is a...
