The Korea Times - Hyundai Motor has unveiled its universal wheel drive system
by placing major driving parts inside a wheel, dramatically increasing the
potential indoor space for electric vehicles (EV), the company said Tuesday.
The so-called
"UNI WHEEL" is in its initial development phase, but the carmaker
believes it will become a game changer for future mobility here and abroad. The
company applied for eight patents for the new wheel system in Korea and other
key markets in the United States and Europe.
Under the system,
key driving components, such as constant velocity joints and drive shafts, are
placed inside the wheel, maximizing potential interior space for passengers or
extra batteries. If the expanded space is used to carry an additional battery,
vehicles equipped with the UNI WHEEL system will be capable of driving for
longer without charging, according to Hyundai.
“We are pleased to
unveil innovative ideas that can serve as a game changer in the future mobility
market,” Park Jong-sool, a senior researcher at Hyundai Motor, told reporters
during a tech conference. “Hyundai Motor and Kia will do their best to enhance
their technological skills, so customers enjoy new and fresh mobility
experiences.”
But the carmaker did
not confirm when exactly it will be commercialized.
“We have just
completed the second developmental phase, so it appears too early for us to
discuss the timeline for its commercialization,” Park said. “Two separate
motors are used to realize the UNI WHEEL system, so the price of vehicles with
it will be higher than conventional ones with one motor. We forecast the system
will be applied to luxury or high-end vehicles first because of the price.”
Most EV batteries
have so far been placed at the bottom of vehicles, and in most cases, indoor
space is reduced in line with battery volume. But EVs equipped with UNI WHEEL
will help maximize space efficiency for carmakers, according to Hyundai.
The system can also
be used for other types of mobility, such as wheelchairs, bicycles and delivery
robots, as the size of the wheel is adjustable, ranging from 4 inches to more
than 25 inches, the company said.
