They can offer added value as a combined trailer drive for e-trucks or as a generator for refrigerated trailers with independent power supply.<\/p>\n<p dir=\"ltr\">\u201cThe technical challenges for the seal are mainly to ensure reliable protection against dirt and water while minimising friction losses,\u201d explains Product Developer Luca Breusa.\u00a0\u201cAs a solution, Freudenberg has positioned the sealing lip in such a way that high contact pressure maximises sealing performance at low rotational speeds. At higher speeds, both the contact pressure and the friction are significantly reduced by the generated centrifugal forces. Depending on the customer\u2019s requirements, the seal can even be fully lifted off the stator, which also eliminates friction, thus significantly increasing the lifetime of the seal,\u201d Breusa explains.<\/p>\n<p dir=\"ltr\">The company has developed two seal designs:<\/p>\n<ul dir=\"ltr\">\n<li><strong>Cassette seal\u00a0<\/strong>offers a double sealing lip and mating contact surface installed in a closed system, featuring precisely matched materials made of stainless steel and special rubber compounds. The required speed ranges and contamination protection can be scaled. The cassette seal stands out for its long service life and high functional reliability. It is capable of achieving up to 500,000 km and protection class IP67. This makes it a maintenance-free, self-lubricating solution throughout its entire service life.<\/li>\n<li><strong>V-seal<\/strong>\u00a0works in an open system. Its particularly wear-resistant elastomers with excellent sliding properties, combined with attractive manufacturing costs, create a plug-and-play solution designed for flexible applications.<\/li>\n<\/ul>\n<p dir=\"ltr\">With these two solutions, Freudenberg bridges the gap between the requirements for high sealing performance and low friction losses. The seal geometry can be scaled to an installation space diameter of up to 530 mm and is adjustable to the respective speed range. This allows the seals to be used in applications ranging from cars to commercial vehicles.<\/p>\n<p dir=\"ltr\"><strong><em>interplasinsights<\/em><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Iranpolymer\/Baspar In-wheel motors (IVM) for electric vehicles offer various advantages.
