Hyundai and Kia have unveiled an progressive EV drivetrain design referred to as the Uni Wheel throughout their “Uni Wheel Tech Day” occasion in Seoul. This new Common Wheel Drive system relocates major parts to the wheel hub, creating further inside house inside the car.
Whereas electrical autos (EVs) have revolutionized design, the normal drivetrain has endured. EVs usually keep the facility transmission technique present in inner combustion engine (ICE) autos, regardless of changing the engine and transmission with a motor and discount gear. Hyundai and Kia’s Uni Wheel system is a paradigm-shifting answer, putting major drive parts inside the EV’s wheel hub.
Not like earlier makes an attempt by different builders, the Uni Wheel makes use of a singular planetary gear configuration with a central solar gear, pinion gears on all sides, and a surrounding ring gear. The system’s effectivity stays excessive, no matter wheel motion or suspension articulation, offering a variety of movement.
This innovation will increase platform house, contributing to extra spacious EV interiors, together with cargo and trunk house. Moreover, the Uni Wheel system permits non-conventional seating configurations, providing design flexibility for future autonomous driving integration.
Whereas the timeline for implementing this expertise in industrial EVs stays unsure, Hyundai and Kia have already utilized for and registered eight patents associated to Uni Wheel in South Korea, the US, and Europe. The businesses specific their dedication to perfecting the Uni Wheel system to supply prospects with a singular and progressive mobility expertise.
