In recent years, no matter whether it is the traditional old brand or the new brand of new pickup trucks entering the pickup truck field, or even the old-car model, the “three measurements†of the body constantly increase, increase, and increase. The trend of “high†development, and even more powerful, is that the “three high†trend in container size is also more pronounced. At the same time, there are also some models that have been given longer axles and wheel moments to accommodate the needs of the Dora and heavy-duty markets. According to statistics, the domestic pickup truck market is currently selling models. The longest body car is the Cheetah CT5 and the length is up to 5610mm; the widest body car is the Jiangling field tiger four-wheel drive vehicle with a width of 1905mm; the longest container size pickup truck is Chang’an. The shrine F30 reached 2020 mm; the widest pickup truck of the container was the Kawei K series, which was 1590 mm; the pickup truck with the longest axial moment was the ZTE Tiger G3 double row with a shaft moment of 3395 mm. The author expects that if there are a large number of single-row seat models in the public pickup truck enterprises, and after going down the market, the “three measurements†size of single-row pickup trucks is likely to reach 6000mm × 2000mm × 1950mm. By then, the tall, mighty image of a pickup truck will be a few streets away from the mini truck. It will be even more competitive with the small light trucks, coupled with its majestic style, strong “heart†power and unsurpassable off-road physical performance. Can be comparable to SUV! However, at the same time as the pickup truck developed toward “high, big, longâ€, the author thinks from a technical point of view that this also needs to have a “degreeâ€, and if it is excessive, there will be big problems. The wheelbase of the vehicle and the length of the vehicle, the wheel moment and the width of the vehicle, and the space between the container and the cab are balanced with each other. The wheelbase is the distance between the two midpoints of two adjacent wheels on the same side of the vehicle and is perpendicular to the two vertical lines of the longitudinal symmetry plane of the vehicle. If the axle moment and the wheel moment are different, the light is the lengthened container. Due to the size, the rear suspension is too long. When the vehicle is running, the longitudinal angular vibration will be too large. When the vehicle is accelerated, braked or uphill, the shaft load is excessively transferred and the axle load is unevenly distributed. As a result, the departure angle When it is small, it causes scratches on the upslope and downslope. At the same time, the turning radius is easily limited and inflexible. Its braking performance and handling stability will be deteriorated and accidents will occur easily. The length of the vehicle's wheelbase has a great influence on the vehicle's handling and stability. In particular, the axle load distribution is an important quality parameter of the automobile. It has the main performances such as traction, passability, braking, maneuverability, and stability of the automobile. The service life of the tire has a great influence. Therefore, some old and new brand pick-up trucks have lengthened and widened the size of containers, and at the same time they have not only extended the shaft moment and widened the wheel moments, but also acted as an example of cutting corners. In the event of quality or traffic accidents, the direct victims are the owners. This is very worthwhile. Causes the car company and the user to be vigilant. A car is a system. The performance of a car depends not only on the performance of the components that make up the car, but also to a large extent on the coordination and cooperation of the various components, depending on the design level and overall layout. These aspects have a decisive influence on the design quality, use performance and product vitality of a car. Therefore, the premise of the ever-increasing size of pickup trucks must be scientific, and it must not be done blindly, contrary to manufacturing theory. In addition, individual vehicle owners must not seek conversions of illegal vehicles without modification qualifications, otherwise the consequences could be disastrous. Everything in the world is divided into two. In order to lengthen and widen the size of the container, the wheel moments are lengthened and widened. The overall arrangement must be adjusted and matched accordingly. Therefore, the body, frame and chassis system will be involved. It can be said that it is a "movement of the whole body." It will inevitably require re-development, re-open molds, production fixtures and fixtures, and re-arrange the production process, so that the four major automotive production processes are involved, and then increase The cost of the vehicle.
