Not long ago, long-range cars announced the world's first new energy super VAN introduction video based on a wire-controlled skateboard chassis, which for the first time installed a series of innovative designs on van models, and is scheduled to be officially launched and delivered in 2023.
The concept of skateboard chassis was actually proposed by general motors as early as 2002, the skateboard chassis word as its name, its surface looks like a skateboard-like chassis, basically flat, the interior by mechanical structural parts, electronic structural parts, can be divided into front axle, middle axle, rear axle three parts.
The front axle includes the front suspension, the subframe, motor, and steering machine; the middle axle includes the battery, collision avoidance structure, and thermal management system; and the rear axle includes the rear suspension, the secondary frame, and the motor.
Break the structure and innovate
The emergence of the skateboard chassis completely broke the traditional car structure, which is not limited to the role of the traditional chassis on the vehicle support, but as an independent platform to use, its biggest advantage is that the vehicle can not only change the battery, but also can change the body, the relationship between the entire body and the frame is like "lunch box" and "box cover", the complexity of the part between the two relying on machinery and harness linking parts will also be reduced.
Thanks to the use of steer-by-wire skateboard chassis technology, advanced steer-by-wire technology used in the aviation field can be realized in the car.
Wire control is to drive the motor through electrical signal transmission, steering, braking, throttle, gear shift control are replaced by electrical signals, there is no mechanical connection between the driver and the wheel, which can make the structure of the whole vehicle modular, the layout is more compact.
At the same time, the body also has more space, the weight ratio of the chassis of the vehicle is more uniform, the center of gravity is lower, the driving is more stable, to a certain extent to prevent rolling, and the safety performance has also been improved.
R&D efficiency improvement Another possibility of expanding the "circle of friends"
The advantages of the skateboard chassis are not limited to the body that can be replaced at any time, but also in the fact that enterprises can launch new cars faster, the traditional vehicle platform needs to redesign the body and chassis according to the different needs of different users when designing derivative models, and the skateboard chassis can allow manufacturers to develop derivative models based on the same chassis according to the needs of different users, so that the research and development cycle of the whole vehicle is greatly reduced. According to the data, the development cost of vehicles using skateboard chassis can be reduced by up to 60%.
For commercial vehicles, the advantages of the skateboard chassis are not only able to adjust the product system and enrich the product structure according to market demand faster, but also can arrange the cockpit space more reasonably and improve the environment inside the car.
A variety of groundbreaking designs Super VAN should not be underestimated
It is understood that in addition to the skateboard chassis, the application of super VAN online control technology for remote cars is also leading. The vehicle can achieve intelligent driving functions above L4 level, using a series of revolutionary innovative designs in small commercial vehicles such as digital magic cargo compartment, B-pillar-free design, intelligent partitioned warehousing, cargo compartment environmental monitoring, etc., which can meet the most popular commercial and passenger dual-purposes.
This skateboard chassis light passenger of the remote car opens the door to the future and presses the acceleration button for the transformation of new energy light passenger products. Long-distance cars have also become famous and become subversives of new energy vehicles in the field of urban logistics.
