Improving technology for manufacturing casting case of truck clutch release cylinder

Abstract

The object of research: Manufacturing technology of body castings for trucks using the example of a clutch release cylinder body made of gray cast iron with flake graphite EN-GJL-200.
 Investigated problem: Finding ways to reduce the weight and size characteristics of cast parts.
 The main scientific results: A mathematical model has been developed that has made it possible to determine the optimal compositions of alloying Cr/Ni – Cu/Ti complexes that ensure an increase in the grade of cast iron by increasing the tensile strength at elevated carbon contents. This makes it possible in the future to reduce the thickness of the walls of the castings, achieving a reduction in their weight and size characteristics
 The area of practical use of the results of the study: Automotive industry in terms of technology for manufacturing cast parts for trucks
 Innovative technological product: Improved technology for manufacturing the clutch release cylinder body due to optimization of melt technology and out-of-furnace processing allows for targeted selection of melt processing modes, ensuring an increase in the strength characteristics of cast iron for cast body parts, thereby moving from the EN-GJL-200 cast iron grade to the EN grade -GJL-250 and EN-GJL-300.
 The scope of the innovative technological product: Foundries of engineering enterprises, in particular those producing trucks, in which iron castings are produced
