Elektrofahrzeuge (EVs) haben einige besondere Anforderungen an die Lager aufgrund h\u00f6here Geschwindigkeiten, mehr Drehmoment, Elektrifizierung und die Notwendigkeit, L\u00e4rm und Reibung zu reduzieren<\/strong>. Im Folgenden finden Sie einen detaillierten \u00dcberblick \u00fcber spezifische Lageranwendungen in EVs<\/strong> und die \u00fcblicherweise verwendeten Lagerarten:<\/p>\n\n\n\n
