This design is called McNamun Wheel, which was invented by a Swedish company. The patent expired on 1992. McNamham wheel is an omni-directional wheel, and the tire is composed of many inclined rollers, which can convert the steering force into the normal force of the wheel, so the wheel can slide sideways.
This seems to be a very simple design, but it is very difficult to apply it to cars. It needs different steering of the front and rear wheels of the car to realize the function of "walking sideways" BYD's independent four-wheel drive technology has just achieved this, and four motors can control four wheels respectively. From this point, BYD's technology is really strong. However, McNamham wheels wear tires excessively.
technical superiority
Looking up at U8, it has two top technologies, Easy Sifang and Yun Qi -P intelligent hydraulic body control system, and has four-wheel independent torque vector control capability, which can realize scene functions such as extreme handling stability, tire blowout control, emergency floating, in-situ U-turn and agile steering.
With the blessing of "Easy Sifang" technology, we hope that U8 not only has the performance, safety and reliability of hard-core off-road, but also has scientific and technological intelligence, and can get rid of difficulties and avoid emergencies in complex road conditions by virtue of its excellent sense of science and technology and intelligent ability, and bring modern civilization outdoors.
