This thesis presents two activities carried out at Brembo S.p.A. during an internship period. In the first chapter, the state of the art of the parking brake will be presented with an in-depth description of its development over time up to the technologies used today. In this first part, all the types of braking systems produced by Brembo will be reviewed and the main components that compose them will be described. In the second chapter we will go into the merits of the activity carried out, in particular, a preliminary description of the design flow for an EPB (Electric Parking Brake) gripper introduces the in-depth description of the implementation of the new automatic flow of the calculations necessary for the design. All the calculations will be described in detail by presenting what are the inputs and outputs of each one so as to fully map the automatic flow before its implementation. The implementation of the flow was performed on Isight® software and then its beta version was tested for the validation of the final result. In the third part of the thesis, the second activity will be presented, which concerns the integration within the HBR (Hot Brake Reclamp) simulation of the new CCB disc combined with its pads. The new configuration was mechanically and thermally characterized through an in-depth analysis of the characteristics of the two components. The thermal and mechanical model that simulates the behavior of the brake caliper assembly, which was already implemented previously, was analyzed in detail and modified for the study of the new configuration. Several bench tests were also carried out to measure mechanical and thermal parameters for the pad combined with the CCB disc.
Nella presente tesi sono presentate due attività svolte presso l’azienda Brembo S.p.A. durante un periodo di stage. Nel primo capitolo verrà, innanzitutto, presentato lo stato dell’arte del freno di stazionamento con una descrizione approfondita del suo sviluppo nel tempo fino alle tecnologie utilizzate oggi. In questa prima parte verranno passate in rassegna tutte le tipologie di sistemi frenanti prodotte da Brembo e descritte le componenti principali che le compongono. Nel capitolo secondo si entrerà nel merito dell’attività svolta, in particolare, una descrizione preliminare del flusso di progettazione per una pinza EPB (Electric Parking Brake) introduce la descrizione approfondita dell’implementazione del nuovo flusso automatico dei calcoli necessari alla progettazione. Tutti i calcoli verranno descritti nel dettaglio presentando quali sono gli input e gli output di ognuno così da mappare interamente il flusso automatico prima della sua implementazione. L’implementazione del flusso è stata eseguita su software Isight® e quindi testata la sua versione beta per la validazione del risultato finale. Nella terza parte della tesi verrà, quindi, presentata la seconda attività svolta che concerne l’integrazione all’interno della simulazione HBR (Hot Brake Reclamp) del nuovo disco CCB abbinato alle sue pastiglie. La nuova configurazione è stata caratterizzata meccanicamente e termicamente attraverso un’analisi approfondita delle caratteristiche dei due componenti. Il modello termico e meccanico che simula il comportamento dell’assieme pinza freno, che è stato implementato in precedenza, è stato analizzato nel dettaglio e modificato per lo studio della nuova configurazione. Sono stati, inoltre, eseguiti diversi test al banco per la misura di parametri meccanici e termici per la pastiglia abbinata al disco CCB.
