Projecção de uma máquina para retirar lona no patim de freio para os autocarros da EMTPM

Abstract

Currently, in the general workshops of EMTPM, during the maintenance of the bus braking system, the removal of brake linings from bus brake shoes is carried out manually, using hammers, chisels, and metal levers. This procedure requires substantial labor and is quite slow. In addition to the delay in maintenance, it demands significant physical effort from technicians and presents considerable operational risks, such as workplace accidents, structural damage to components, and lack of precision in the execution of the service. The present work aims to design a machine that enables the mechanical, safe, standardized, and efficient removal of brake linings from brake shoes for EMTPM buses, in order to reduce the physical effort exerted by workers during the removal process, while ensuring ergonomic and safety conditions. For the development of this project, bibliographic research was conducted on bus braking systems, along with consultation of manuals and catalogs for the design of a machine to remove brake linings from brake shoes, ensuring that it meets mechanical and ergonomic requirements, ease of maintenance, and economic feasibility. With the implementation of this project, a reduction in maintenance time, as well as a decrease in the risk of accidents and injuries, is expected.
