Different housings are used to protect electronic components, such as battery systems or power electronics, from external environmental influences and to attach the components to the interior in order to ensure that they function properly during vehicle operation. The requirements for the housing depend on the electronic system and drive concept. Different materials and manufacturing processes are currently used.
FEATURES
Unstable, thin-walled components (susceptible to vibration)
Construction as a cast tub or as a frame construction made of hollow profiles
Partly low-silicon aluminium
Large area (2 x 3 m)
Mainly drilling and milling operations and threading
Accuracy and surface requirements for cable bushing and cooling connections
A causa delle dimensioni sempre più grandi delle batterie, si ricorre a soluzioni modulari per diverse classi di potenza e livelli di autonomia. A tale scopo, i profili estrusi di alluminio sono saldati insieme per formare un corpo.
REQUISITI DI ASPORTAZIONE TRUCIOLO
Materiale sottile a più strati
Foratura: vibrazioni e formazione di sbavature. Formazione di anelli sull’utensile → Interpolazione elicoidale / foratura orbitale previene la formazione di bave e anelli
Fresatura: il materiale sottile tende a vibrare → Meno vibrazioni grazie alla geometria ottimizzata del tagliente
Come sede dell’elettronica di potenza e delle batterie più piccole dei veicoli ibridi, vengono di solito utilizzati corpi pressofusi in alluminio. Le complesse strutture del corpo sono progettate con canali di raffreddamento integrati.
REQUISITI DI ASPORTAZIONE TRUCIOLO
Fresatura delle superfici di tenuta (requisiti di superficie parzialmente speciali)
Fresatura delle superfici di collegamento per elettronica e celle delle batterie con una lunga sporgenza dell’utensile
Esecuzione di prefori (> 50 fori per componente)
