Abstract

The invention provides an electric auxiliary turbocharger structure based on duct-air gap air intake. The structure mainly comprises a bearing seat, a motor with a large air gap, an air compressor volute with a duct, an air compressor impeller, an intermediate body and a turbine, the motor is mainly composed of a stator and a rotor, the bearing seat is connected with an inlet section of the air compressor volute, the front end of the motor rotor is provided with a bearing and matched with the bearing seat, the rear end of the motor rotor is coaxially connected with a rotating shaft of the turbocharger, and the motor stator is in interference fit with the inner wall of the inlet section of the air compressor volute. The motor is mounted in front of an inlet of an air compressor; the air inlet requirement of the air compressor is met through the duct and the air gap, the motor is far away from a turbine heat source, the heat dissipation condition is improved, the working reliability of the motor is improved, in addition, the motor can be additionally arranged on a traditional turbocharger only by changing the air compressor volute and a turbine rotating shaft, and the electric auxiliary turbocharger is formed. Airflow flowing through the duct and the air gap further solves the heat dissipation problem of the motor.

Description

technical field [0001] The invention belongs to the technical field of electric auxiliary turbocharging, and in particular relates to an electric auxiliary supercharger structure based on duct-air-gap intake. Background technique [0002] The requirements for low-speed torque and transient response of contemporary internal combustion engines continue to increase, and traditional turbocharging technology is developing into electric-assisted supercharging technology based on high-speed motors. The common electric-assisted supercharger adopts the structure of the motor in the middle, and the overall structure is compact, but the disadvantage is that the bearing and lubrication structure of the original turbocharger have been greatly changed, and the heat dissipation of the motor is difficult. Therefore, there is a need for an electrically assisted turbocharger structure, which facilitates electrification of traditional turbochargers and solves the heat dissipation problem of hi...
