In today's society, more and more families have their own cars, and at the same time, Chinese people have higher and higher requirements for cars, especially in terms of space and ride experience. The small space of the car will give people a feeling of aggrievedness. For example, many models have a high or low bump in the middle of the rear row, which affects the driving experience of the rear row to a certain extent.
Many cars now have a raised layout in the rear row, and most of them are concentrated on rear-wheel drive and four-wheel drive models, but there are also front-wheel drive models, such as Volkswagen Tiguan, Jetta, Mazda Angkesai and so on. So since it affects the ride comfort, why not remove it when designing it? In fact, designers are always bothering! What is under the protrusion of
?
Normally, the bump in the rear row is caused by the exhaust pipe, brake pipe pipeline or transmission shaft under the chassis. For the flatness of the chassis, there is such a bump in the middle of the rear row, which sacrifices the interior of the car. space. However, some cars cleverly use the form of the side layout, and its rear floor is almost flat. The difference between the height of the
protrusion
The height of the protrusion
has high and low points, in fact, it has a lot to do with the driving mode of the vehicle. Parts, just for the exhaust pipe and other parts to pass. The bulge of rear-drive vehicles is generally very high. After all, the power of the engine has to be transmitted to the rear wheels through the drive shaft, so this is affected by the driving mode.
Another situation is that some front-wheel drive vehicles have very high rear bumps, because some models have front-wheel drive and four-wheel drive versions for consumers to choose from, and manufacturers will not produce two in order to save costs. Different molds come out, so the two-wheel drive and four-wheel drive models share the same set of molds, so that some front-wheel drive vehicles will have very high protrusions. Does
SUV have advantages?
People who often drive SUVs or ride SUVs are more confused. Many SUVs are now equipped with four-wheel drive systems, but why many SUVs have a flat rear floor?
Because the ground clearance of SUVs is generally higher than that of cars, there is more space available under the chassis. Exhaust pipes, drive shafts and other components basically do not occupy the space in the car, so the rear floor of some SUVs can be pure Flat state. Can
bumps be cancelled?
With the development of automobiles in recent years, it is easy to change the bumps on the rear of a car. Since automakers can solve this problem, why not do it? This is based on the concept of safe car manufacturing. If you fold a piece of metal, a "reinforcing rib" will be formed, which greatly strengthens the hardness of the metal. The same is true for the car chassis. The car chassis is designed as a groove, which means that it has been folded 4 times. Compared with the flat chassis, there are four more "reinforcing ribs", thus improving the safety!
Generally speaking, there is a bump in the middle of the car's rear row, which is also the helpless action of the car dealer. It also shows that it is a good intention and protects us to a large extent. In fact, the existence is reasonable. If the protrusion is not high, the ride comfort of the middle passenger will be improved; those with higher protrusion have a lower center of gravity and relatively better handling.
