Abstract

The invention belongs to the field of turbochargers of automobile engines and particularly relates to a turbocharger intermediate. The turbocharger intermediate comprises an intermediate body and a diffusion plate which are integrally formed, a vaneless diffuser and a vane diffuser are arranged on the diffusion plate, the tail end of the vaneless diffuser is connected with the front end of the vane diffuser, and the vane diffuser comprises a plurality of diffusion vanes fixed on the diffusion plate. The turbocharger intermediate is reasonable in structural design, reliable in operation process and high in stability.

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...
