Methodology for Determining the Process of Riveting Brake Linings for Heavy Commercial Vehicles 2013-36-0029

During the development of a new friction material, besides the interface between lining/drum is also fundamental take in account all aspects involving the attachment of the linings on the brake shoes.

This paper presents an optimization approach to the development and manufacturing parameters of brake linings, applied on medium and heavy duty commercial vehicles, aiming to assure the correct specification of the riveted joint clamp forces. These evaluations were conducted based on the quality tools documents and the theoretical aspects of the product usage as well as the modeling of key elements of the referred mechanism throughout various known applications. A calculation methodology was developed based on brake geometry, its generated forces and braking reactions required for each vehicle family. Taking in consideration the mathematical modeling of lining riveting process, the study incorporated calculated parameters on the production of new parts to proceed with bench and dynamometer preliminary tests. After theoretical approach an optimized process of lining riveting was implemented on the riveting machine focusing on its capacity to generate the required clamp force on a production scale. With the results from experimental testing, further vehicular performance correlations were performed aiming durability endurance maximization on proving ground tracks.

The main objective of this paper is to show all steps involved on defining a robust riveting process based on calculation, experimental testing and rooted on vehicular correlation and validation aspects, obtaining a method to specify the required clamp force of the riveted joint on brake linings development.
