Embodiment Construction

[0019] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] Such as Figure 2~6 As shown, a turbocharger volute of the present invention includes a volute casing 4, a volute flow passage 1 is arranged in the volute casing 4, a partition wall 2 is arranged in the volute flow passage 1, and the volute casing A volute profile 5 is also set inside the body 4, and the inner side of the volute profile 5 forms a volute outlet 6, and the volute tongue 3 is arranged in the volute housing 4 corresponding to the inner part of the volute outlet 6, and the volute outlet 6 rotates centrally The central axis 7 is set in the area; a part of the ring on the inner wall of the volute profile 5 is coaxially arranged with the central axis 7, and a part of the ring on the other side of the inner wall of the volute profile 5 is eccentrically arranged with the central axis 7. At this time, the The central axis of th...

Abstract

The invention belongs to the technical field of turbochargers, and relates to a turbocharger volute. The turbocharger volute comprises a volute shell, wherein a volute flow passage is arranged in thevolute shell, a partition wall is arranged in the volute flow passage, a volute molded line is further arranged in the volute shell, the inner side of the volute molded line forms a volute outlet, a volute tongue is arranged at the position, corresponding to the inner side of the volute outlet, in the volute shell, and a central shaft is arranged in a central rotating area of the volute outlet; and a part of the circular ring on the inner wall of the volute molded line is coaxially arranged with the central shaft, and the part of the circular ring on the other side of the inner wall of the volute molded line is eccentrically arranged with the central shaft, so that the volute outlet is in a non-normal circular shape, and the non-normal circular shape of the volute outlet is distributed inthe axial direction of the volute molded line. The volute can effectively reduce the collision risk between a turbine and the volute, further improves the reliability of a turbocharger, and has low influence on the performance of the turbocharger.

Description

technical field [0001] The invention belongs to the technical field of turbochargers, and relates to a turbocharger volute. Background technique [0002] A turbocharger is a device used to compress and pressurize atmospheric air to feed the intake air of an engine. Ordinary superchargers generally include a turbine volute housing 4 and a turbine 10 installed in the volute housing 4; the volute housing 4 is installed downstream of the exhaust manifold of the engine; the turbine shaft is usually connected to the turbine and the compressor The floating bearing and thrust bearing system support in the middle shell; the rotation of the turbine 10 causes the compressor impeller installed at the other end of the coaxial to rotate to compress the air and collect and transport it to the engine intake end through the compressor shell. [0003] When the car is running under different road conditions and speeds, the engine will burn exhaust gas of different temperatures and discharge i...
