Patents Assigned to Rotao Tech Ltd
  • Patent number: 11220175
    Abstract: The present disclosure provides a machine and mechanism of an electrically controlled low-unsprung-mass wheel unit for vehicles. The design incorporates independent propulsion/braking, axle control, steering, and suspension (IPASS) of each wheel during vehicle movement. The purpose of the design is for a traction-adaptively-optimization (TAO) control which include but not limited as the following: 1) better road surface gripping and ride quality by lower unsprung mass; 2) safer, quicker, and sharper turning ability—transformative turning; 3) adaptive obstacle avoidance; 4) a list of new, unique, and advanced vehicle motion features. The mechanism comprises at least: an axle adjustment that controls the distance of a wheel from the vehicle body, which allows for the outward extension of the wheel via a slider. The slider is connected to a linear actuator, which is powered by the first independent electric motor for track width adjustment.
