First of all, the concept of a platform is not "manufacturing workshop", nor is it a production line, nor is it a factory building. Many of the current production lines are flexible production lines, which means that the same production line can produce different models. The factory buildings will not be moved for decades. Of course, expansion and construction of new plants are not included. Let's talk about the "platform" often said, the platform can be abstractly understood as a product plan designed by a car company for a class of vehicles or multiple types of vehicles. From this perspective, the platform is a very illusory concept. For example, the manufacturer hopes to design a compact sedan (such as Ford Focus) and hopes that other brands can also benefit from the design of this model, and also hopes that it can be expanded into a mid-level sedan platform to produce medium-level cars. Cars or MPVs (such as New Mondeo, S-MAX), this kind of planning we can regard as a very important part of the "platform". After this kind of planning, it is natural to start with specific designs such as suspensions, hydraulic systems, electronic systems, interior and exterior modeling, and body structures. Because there are platform concepts, these components will be considered when designing Sex, so many parts are modularized. Here, the concept of platformization and modularization is not just whether the suspension is shared, but even the design of the body structure can be shared. At the same time, different types of suspension structures can be used for the same model of the platform (for example, the Volkswagen Caddy rear suspension under the PQ35 platform is not a multi-link structure, but a leaf spring is used as the integral rear axle of the elastic element). Also continue to give Fox examples, from the appearance of the Fox, Mazda 3 and Volvo S40 have similar places but there are different places, but they are the same platform products, but can not be said they are the same platform is exactly the same, but for a different look. Because different car manufacturers will also modify the platform and launch their own products based on it, but from a common point of view, these three cars in the body structure, suspension structure has many similar places, steering system, brake The system's components are even the same. For example, the new Accord, this model is a new generation of replacement models, because its body structure has been redesigned (by adding the ACE structure, the proportion of high-strength steel increases), the suspension of the specific structure has been redesigned (although the form is still the former After the fork arm multiple links), the interior layout has also changed (this is also a big sign of a new generation), not to mention modeling. Another example of a counterexample is to better understand that the new Excelle launch of the new Excelle is not a replacement model, but a small variant (Facelift. Although General said it is something new, but it is not actually a replacement category, because it's The body structure has not been redesigned, the suspension structure has not been redesigned, and the interior layout has not changed (only the panel was changed).
Electric Vans are eco-friendly vehicles, including Chinese electric vans, designed to operate on electric motors and batteries.
