PERIODO: NOVEMBRE - DICEMBRE

Il modulo intende fornire la descrizione e l’analisi delle principali trasmissioni in uso nel settore automobilistico. Sono forniti schemi ed elementi utili per la modellazione ed il confronto tra le diverse soluzioni. Sono analizzati alcuni aspetti dei sistemi manuali (vibrazioni torsionali) e automatici (sistemi e logiche di controllo)

The aim is to give the participants the description and analysis of the main transmissions used in the automotive field. Attendants will be provided with schemes and other elements useful to model and compare the different solutions available in the market. Some issues of manual (vibrations) and non-manual transmissions (control systems and logics) will be analysed.

Introduzione alle trasmissioni: necessità delle trasmissioni, dispositivi di avviamento (frizioni/convertitori), dimensionamento dei rapporti di trasmissione.
Analisi e modelli dei principali tipi di trasmissioni: manuali (con analisi di dettaglio del cambio marcia), robotizzate, automatiche (a rotismi epicicloidali), continue (CVT), ibride (serie, parallelo, serie/parallelo, dual mode).
Analisi di differenziali open, a scorrimento limitato e autobloccanti: influenza sulla dinamica del veicolo.
Esempi di problematiche vibrazionali: modelli per l’analisi dei fenomeni di rattle e clonck.
Cenni a logiche di controllo per sistemi ibridi.

Introduction to transmissions: why they are needed, launch devices (clutches/torque converters), choice of the transmission ratios.
Analysis and models of the main architectures: manual (with detailed analysis of gearshifts), robotized, automatic, cvt, hybrid (series, parallel, series-parallel, dual mode)
Analysis of differentials: open, limited slip and self-locking. Influence on vehicle dynamics.
Vibrational issues: models for analysis of gear clonck and rattle.
Introduction to control logic design for hybrid systems.
