Why is there a bump in the center of the car’s back row?Knowledge posts

Maybe you've discovered it a long time ago

a lot ofcarThere is one in the center of the back rowRaised

And this bump alsoHigh and lowBut no matter how low it is, it directly affects the comfort of the rear seat

If two people sit in the back row

It doesn’t matter if you get on the left and right.

And if you want to get on and off on the same side

The one inside will be more strenuous to get in and out

Have to climb over the mountains

The saddest thing is when there are three people in the back row

The one in the middle will be very embarrassing

But even though it is so inconvenient

Some drivers like it

Especially the beauties sitting in the middleWear a miniskirtwhen

This compulsory

Cheating

Still very interesting

But the problem is still coming

Why is this bump used?

Why is there that bump

Some people say it is mainly for partitioning

Just like separating the living room and dining room during house renovation

This is a silly break from Xiaoxiao's point of view

So Teng Xiaoxiao specifically consulted friends far abroad

A senior car designer

I know after asking

The reason for this bulge

Totally

Chassis and power train layout

s reason

usually

The center of the chassis must pass

Exhaust pipes, brake pipes and other pipelines

Or drive shaft, or arrange rear suspension

For the chassis level

I had to sacrifice the space in the car as a last resort

So the middle of the back row will bulge

Then why is the bulge high and low?

In other words, this has a certain relationship with the driving mode of the vehicle

Front rear drive

To passtransmission shaftTransmission of power to the rear wheels

So the bulge will be higher

4WD because ofRear axle,Shock absorber

Also consider increasing the ground clearance to improve passing performance

So the bump is generally higher

By contrast

The bump of the front-wheel drive vehicle is generally lower

But because some vehicles have multiple versions such as front-wheel drive and four-wheel drive

And in order to save costs

The car factory will not make two different molds

So some front-wheel drive cars have very high bumps

Therefore, simply by the height of the bump

To judge that the front-wheel drive and rear-wheel drive four-wheel drive are not feasible

In addition, someone said

Raised height and

Vehicle design philosophy and laws

Have a certain relationship

For example, some vehicles are basically driven by one person

Almost no people in the back row

It doesn’t matter if the bulge is higher

And if the vehicle is designed with 3 people in the back row

Then the bump height will be minimized

Speaking of law

It is said that Europe has stipulatedexhaust pipeNot too close to the ground

To avoid high temperature damage to lawn pavement, etc.

And in the case of the same chassis height

To achieve this effect

Can only use the space in the car

But you must also know

Many cars have no bumps in the rear

Why is this?

There are two situations

One is the high ground clearance of the vehicle itself

There is enough space available outside

No need to take up space in the car

One is that the exhaust pipe is designed very low

Does not take up space in the car

Such a small bump

There are so many ways

Didn't expect it?
