SEOUL -- Hyundai auto group has unveiled a new type of car wheel designed exclusively for future electric vehicles. Unlike ordinary wheels that receive power delivered from an engine or motor through drive shafts, the new "Universal Wheel Drive System" has its own drive system built into the interior of the wheel.

Hyundai Motor and its brother company Kia held the "UNI WHEEL Tech Day" in central Seoul on November 28 and unveiled the universal wheel. Hyundai said that the wheel with a built-in drive system can help carmakers drastically increase the interior area of vehicles.

"The Uni-Wheel has opened new possibilities," Hyundai said, adding: "Uni-Wheel incorporates the functions of the electric car's brake system, drive shaft, and constant velocity (CV) joints into the wheel. By positioning the motor near each wheel, a flat-floor configuration is enabled."

The universal wheel can maximize the performance of purpose-built vehicles (PBVs) such as an all-terrain rescue vehicle by increasing the passenger capacity or creating extra room for rescue equipment.

Hyundai said that each universal wheel that consists of a sun gear, four pinion gears, and a ring gear can play the role of a drive system. The pinion gears are all interlinked to allow the all-in-one wheels to be positioned as part of a multi-link mechanism, allowing them to move up, down, and sideways.

"We are pleased to present innovative ideas that can be a game-changer in the future mobility market. We will do our best to enhance the completeness of technology so that customers can experience mobility in a completely new way," Hyundai and Kia's Advanced Technology Institute researcher Park Jong-sool said.
