By joining Renault to do this internship, the main goal was to work on static cold sealings for E-PWT. With the electrification and hybridization of powertrains, new functional demands appear on sealing. At first, a literature survey of used sealing technologies and their application in automotive powertrains will be done to learn and understand better all static cold sealing technologies. This part will explain what cold static sealing is and detail the 3 mains sealing technologies/principles used for these sealing needs. Then, we will take into account the new functional demands and limits and make an overview on its impact on sealing. This will be completed by a benchmarking part that will help to understand more precisely sealing technologies and to define sizing parameters. This will be a way to identify which sealing types are used for which applications and to observe sealing strategies from competitors. Finally, we will try to identify some differences between E-PWT and TH-PWT sealings. Then, a defective case will be studied. First, possible root causes for the problem will be investigated and then a correction will be proposed starting by analysing the functional demand and then by sizing a design that would respect these demands. We will conclude by a review of what has been done during the internship, personal and technic benefits.
