Description

technical field

[0001] The invention belongs to the field of automobile engine turbochargers, and in particular relates to a turbocharger intermediate. Background technique

[0002] In recent years, the performance of the turbocharger has been greatly developed, but there is not much change in the structure. The reliability of the turbocharger is still a big problem for the turbocharger manufacturers, and the turbocharger bearing is the key to the turbocharger. The weakest link in the reliability of the compressor, the main failure mode is that the oil film cannot be effectively established due to thermal load, and the bearings dry friction and fail quickly. How to effectively cut off or reduce the influence of turbine end heat on the intermediate is an important factor related to the reliability of the turbocharger. For superchargers with particularly high thermal loads such as gasoline engines and passenger cars, a water cooling device is usually designed on the middle sh...

Embodiment Construction

[0028] like figure 1 and figure 2 , a turbocharger intermediate body, including an intermediate body 1, one end of the intermediate body 1 is provided with a diffuser plate 2, the intermediate body 1 and the diffuser plate 2 are integrally formed, and the center of the diffuser plate 2 An impeller hole 6 for installing the impeller 11 is provided, and a diffuser is provided on the diffuser plate 2, and the diffuser includes a vaneless diffuser 8 close to the impeller hole 6 and a vane diffuser 12 far away from the impeller hole 6, The edges of the vaneless diffuser 8 and the vane diffuser 12 are connected, and the vane diffuser 12 includes a plurality of diffuser vanes 7 , and the diffuser vanes 7 are fixed on the diffuser plate 2 . The integrated intermediate body 1 and diffuser plate 2 simplify the structure, reduce the processing cost and time, simplify the assembly process, ensure the concentricity of the holes and the overall assembly accuracy, and eliminate the noise g...
