Perhaps many children's shoes discover
Many car back seats will have a convex
This convex is high or low
All will affect the comfort of riding
Usually under the circumstances,The protrusion of the rear row is because the chassis below must pass through the exhaust pipe、brake pipeline pipeline or drive shaft,For the flatness of the chassis,So there is such a protruding in the middle of the rear row,Sacrifice the space inside the car。
The car is raised between the front and the back of the car,Is a structural design,The purpose is to improve the rigid strength of the vertical of the carriage,At the same time, it also leaves the backward space back to leave the space to make it impossible to affect the passability of the chassis。
11180_11198,Considering the upper and lower bumps of the rear bridge and the left and right swing (There are universal sections seabet ioon the drive shaft),Its requirements for passing space will be larger than the front -drive,So,The raised bump of the rear -drive car is much wider than the front -drive。
Generally there will be such a raised place in the rear drive of the rear drive,Because the transmission shaft and the exhaust pipe require this space。Ahead -drive cars generally only have exhaust systems here,Therefore, it will be much lower,Some are even flat。But some merchants make a raised chassis in order to save production costs,So if you see the front -wheel drive, you don’t need to be too strange if you have raised the front -wheel drive。If it is the same version of the four -wheel drive car,The protruding height in the rear will be relatively higher。As for SUV、MPV models,Because their chassis is higher,No need to leave space for the exhaust system,Therefore, no need for this bump。
This is related to the design concept。The raised may not have a steel beam,No raised does not mean that there is no steel beam。Let's go,Questions about the protruding question of the rear row,Four words can be solved- "Design Concept"。Some A -class cars,It may be considered as a car owner when designing.,Few people sit in the back row、less when you are sitting in three people,So even the front -wheel drive doesn’t care if the rear bump will be too high。and some intermediate cars,Considering that the second row may sit three people,So try to get as much as possible。At the same time,This is related to the design concept at home and abroad,The raised height is to seabet mypursue design balance。
This "protruding" at the foot of the rear seat is not available for safety settings,This "raised" and the strength of the frame is not much related。The strength of the frame is a very complete concept,Generally at the beginning of the vehicle design,The manufacturer has fully considered the problem of the rigidity of the frame,instead of "raised" the rear seats, how much to accommodate the rigidity of the frame。
For a more common example, The "raised" in the center of the rear seat of the Camry brand is relatively flat,and the "protruding" drum bag of the account of the account is larger,But there is no data confirmation The collision security of account is much higher than CAMRY,or prove that the frame of ACCORD is much higher than CAMRY。
The rear floor is flat. Generally, there is only one major disadvantage,That is, the position of the exhaust pipe will be compared with,Impact passability,People who run badly should know this。
rear row convex and non -convex, all have the reason for its existence.
The exhaust pipes of some models are embedded in the site
Some models exhaust pipes outside the chassis
Ping in it , the outside is not calm,
The flat outside, the car is raised,
As for which reason, the benevolent sees benevolence.
No convex, passengers in the back row do not need to split, it will be more comfortable,
convex,General chassis will be lower,The center of gravity is lower,Good for control。
