Serpentine gear is better than inline gear in appearance and function, but it is limited in quality and has many shortcomings, so it has not been fully popularized.

For example, there are two Lanzhou Lamian Noodles. The one at the intersection is really better than the one downstairs, but it is only a little better.

Not everyone does that. Coriander was fresh for 6 hours and then went to this intersection farther away to eat.

The snake gear is more complicated, but it can prevent operation errors.

The advantage of 1 snake gear is that it can prevent the wrong gear from being hung to some extent.

Zhu's paper published in Tianjin Science and Technology magazine shares with you the development of linear operation shifting.

As mentioned above, when the snake gear shifts gears, the shift lever needs to complete the lateral operation along the stepped guide groove before it can shift gears vertically.

So every step of the ladder structure can realize the limit function of the gear, and can't pull it up and down directly?

In-line gear, because the guide groove is straight, it can only complete the guiding function, but not the limit function.

To put it simply: the snake gears are staggered, and the straight gears can be pulled to the end. If you are not careful, there is really the possibility of hanging the wrong file.

However, snake gears are also more complicated, and drivers need longer time to remember and adapt.

Kind of like cooking. Although the dishes with complicated steps are delicious, they are more difficult to cook, right?

Huang Xianqiang of Qilu University of Technology has a paper entitled "Application Research of Interactive Design in Industrial Design".

It is said that the more complex the product, the more functions it has, and the heavier the cognitive burden of people.

If you have just come into contact with the driver friend of the snake stall, you may really be confused about where the snake stall is and where it is.

The visual effect is more stable, but the cost is higher

In addition, snake gears are different from in-line gears in appearance.

Hong Xihua of Hunan University has a paper to share with you, the research on product tension design.

It says: In industrial design, a broken line is a line formed by connecting two straight lines through folding points. Right-angled broken lines look more stable and give people a sense of balance, while some lines that tend to be straight are slightly dull.

On the roof, the snake gear composed of broken lines looks more stable. This more business-oriented model is conducive to creating this sense of stability. The disadvantage is that the cost will be higher than that of in-line gear.

Huang of Ningbo University also has a paper, "Design of Electronic Shift Mechanism of Automobile DCT".

It said: It is not easy to design and arrange the matching electrical components because of the complex trajectory of the snake gear.

Moreover, a plurality of dust-proof sheets need to be combined together, and the process is more complicated and exquisite. If the dust-proof sheet is not handled properly, it will break and break during use ... and so it is.

For technical and cost reasons, although the snake-shaped gear looks good in visual effect and can prevent the wrong gear from being hung to a certain extent, some car companies are useless.

Now it is replaced by electronic gears.

However, both snake gear and straight gear belong to mechanical gear shifting mechanism, which has been gradually replaced by more advanced and better electronic gear.

Wen Jiwei of Jilin University has a paper entitled "Research and Design of Functional Safety of Electronic Shift System", which says.

The electronic gear shifting system judges the driver's target gear by sensing the driver's operation of various electronic gear shifters such as handles and panels, and drives the gear shifting actuator to perform gear shifting operation.

This form can be said to inherit the advantages of snake gear, and its appearance is more perfect. Theoretically, it can be made into any shape to adapt to the interior style of the vehicle.

At present, the common ones on the market are: Mercedes-Benz breast-blocking type; The rocker of BMW is a big chicken leg; Honda's button type; Land rover knob ...

And because the computer is actually shifting gears, it can effectively avoid hanging the wrong gear. If it is wrong, people won't do it. Relatively speaking, it will be much safer.

Snake gear has better function and appearance, but it has disadvantages.

Generally speaking, the snake gear is better than the straight gear in function and appearance, but because it is really only a little, it has not been widely promoted.

Plus, from the perspective of manufacturers, money also has disadvantages, right? It has another disadvantage that it is useful, so not every car is like this.

I really want to be beautiful and useful. Newer cars are generally modern electronic gears. At that time, a snake, a straight line ... a circle will do.

You see, they also make buttons. At this time, if you want to look good and use them well, it has been organically unified.
