Abstract:
The automotive industry seeks for lighter components in every new project. Due to strict regulations in CO2 emission and fuel consumption, design engineers are always dealing with huge challenges to manage weight reduction without structural damage for the application and manufacturing processes improvements.The drum brake system is commonly used in compact cars. This system uses two pins and two flat plates to fasten the brake shoe in the drum. A new geometry of anchor pins may contribute to achieve strict targets such as weight reduction, enhance the structural performance and also bring benefits for manufacturing processes.This work presents a new design of a lightweight drum brake anchor pin, which may contribute to the mass reduction through structural, fatigue and metal forming process simulation.
