Abstract
A turbocharger heat shield comprises a shield body and is characterized in that a recessed ring is formed in the top middle of the shield body by means of downward punching. The heat shield is less prone to plastic deformation, namely anti-deformation capacity of the heat shield is increased, and accordingly waste gas and heat from a turbine shell can be fully tightly sealed by the heat shield, parts of a middle body can be protected, the service life of a turbocharger is prolonged. The turbocharger heat shield is simple in structure, good in seal effect, long in service life and the like, and integral performance of the turbocharger is protected effectively. When the turbocharger heat shield is launched on the market, satisfactory effect is achieved, and the turbocharger heat shield is well received by customers.
Description
Technical field
The present invention relates to a kind of auto parts machinery, particularly relate to a kind of turbosupercharger thermal shield.
Background technique
The turbosupercharger thermal shield.It is positioned at the turbine case of exhaust-gas turbocharger and the binding site of intermediate, closely cooperates with turbine case and intermediate, and majority has certain crush.The effect of thermal shield is to stop the high heat of engine exhaust in the turbine case too much to conduct the intermediate that rotates component at a high speed to comprising, and stops a plurality of vitals of pressurized machine to be subjected to temperatures involved, optimizes pressurized machine internal work environment.After existing turbosupercharger thermal shield used a period of time, thermal shield easily produced plastic deformation, causes thermal shield closely to contact with fixed tray on the turbine case and intermediate, thereby reduced thermal shield heat-insulating and sealing ability.Make high-temp waste gas in the turbine case flow to intermediate and motion assembly by the slit that the thermal shield distortion produces, the heat of high-temp waste gas and carbon distribution can make the moving parts distortion of motion assembly and stuck very soon, and then cause the pressurized machine life-span to be reduced and damage.
Summary of the invention
The objective of the invention is for overcoming defective and the deficiency that above-mentioned prior art exists, and provide a kind of non-deformability stronger thermal shield.
The technological scheme that adopts is:
A kind of turbosupercharger thermal shield comprises cover body, it is characterized in that the downward impact briquetting in middle part of described cover body end face has a concave ring, and the structural elasticity of thermal shield is strengthened.After assembling was used, thermal shield was difficult for forming plastic deformation, and namely the thermal shield non-deformability strengthens, thereby thermal shield can be sealed fully closely from turbine case waste gas and heat, each parts of protection intermediate.Prolonged the working life of pressurized machine.
The present invention has simple in structure, and advantages such as good sealing effect, long service life have effectively been protected the overall performance of turbosupercharger, after putting goods on the market, obtain promising result, are subjected to client's favorable comment.
