Double-turbocharging structure

Abstract

The invention discloses a double-turbocharging structure which includes a rotating shaft, a left impeller, a left impeller shell, a rack, a locking nut, a right impeller shell and a right impeller. The left blade shell is fixedly installed in a mounting hole in the left side face of the rack through screws, the left impeller is installed in a central hole of the left blade shell, a rotating shaftis installed in a central hole of the left impeller, and the right end face of a rotating shaft step abuts against the left end face of the left impeller. The right blade shell is fixedly installed inan installing hole on the right side of the rack through screws, the right impeller is installed in a center hole of the right blade shell, the right impeller is installed on the rotating shaft, theleft end face of the right impeller abuts against the right end face of the left impeller, and the lock nut is installed on the rotating shaft and abuts against the right end face of the right impeller. The double-turbocharging structure has simple structure, the supercharging efficiency of the turbine structure is improved, dynamic performance of a vehicle, apparatuses and equipment is improved,and the energy utilization efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of turbocharging, and in particular relates to a twin turbocharging structure. Background technique [0002] In the automotive industry, more and more turbochargers are used. The existing turbocharger structure improves the vehicle's supercharging efficiency, especially the electric-driven turbocharger.
