Tank U-turn is a technology introduced by automobile manufacturers modeled on the in-place steering function of real tracked tanks, which helps to reduce the turning diameter of vehicles and improve passability in complex road conditions, and Toyota Land Cruiser, Lexus LX570, Haval H9, Tank 300 and other automotive products with excellent off-road performance have this function. Traditional fuel vehicles due to mechanical structure restrictions, can not really restore the tank U-turn, but by locking the one-sided rear wheel, the use of in-situ dragging way to shorten the turning diameter, the disadvantage is that the applicable scene is relatively single, while the tire wear is more serious, so the actual use value is not prominent.
After the automotive industry enters the new energy era, with the increasing maturity of the motor drive system, some manufacturers use the mechanical mechanism advantages of the motor drive to perfectly reproduce the in-situ steering function of the crawler tank, and greatly improve the practicality of this function. Emerging electric vehicle manufacturer Rivian is one of the few brands that master this technology, Rivian's R1T electric pickup truck uses a four-motor drive system, through the 4 motors independently control the wheel rotation can achieve both sides of the wheel reversal, so as to achieve the same effect as the tank on both sides of the track reversal, to achieve the real in-situ rotation maneuver.
However, although Rivian has advanced tank U-turn technology, it has not been applied to mass production models, but Ford, which is slightly behind in the field of electric pickup trucks, has the opportunity to take the lead in realizing the actual mass production of electric pickup truck tank U-turn technology. As early as October 2020, Ford has applied for a patent for tank turning technology, but has not been exposed and publicized, but hidden until recently chose to publish relevant information, which is enough to see that Ford has already begun to prepare in the field of electric pickup technology. The only question at the moment is how the Ford F-150 EV tank U-turn technology will be implemented, the F-150 EV is only available in a dual-motor version for the time being, and it is not possible to achieve individual control of each wheel like the Rivian R1T.
According to the exposed patent introduction, Ford changed the direction of movement of the wheels on both sides by connecting different axles to the tires on both sides of the vehicle, and changing the direction of the wheels on both sides through the different directions of operation of the shafts, so as to achieve the "two sides of the tires moving in the opposite direction" required for the tank to turn. In this way, more mechanical structures need to be added to the drive motor, so that the drive shaft on both sides can achieve reverse movement, which is the same as the independent control drive principle of the hub motor, although the mechanical structure of the motor part is more complex, but it can save a certain cost and maintain the low and affordable price of the F-150 EV.
