What does PDK stand for? Official name: Meaning of Porsche Doppelkupplung

Porsche's PDK is a dual clutch transmission

As those who read this blog regularly know, I love Porsche 911, I also love driving Porsche 911, but I understand Porsche's mechanical After that, I am impressed by the technical difficulties and never talk about them in a difficult way.

Hmm ... I tried to write something like "I don't talk", as if a talented hawk was hiding his claws, but I'm sorry.

Yes, what should I hide? In my case, it's just "I can't talk because I really don't know anything" (laughs).

Yeah, no, you all already know that ^^

I don't know much about the mechanical things about Porsche (no, about cars), but running Porsche is very fun, and I just feel that "Porsche 911 is amazing" with my own sensibility and feeling, and entertain. I have received it.

By the way, what is the dual clutch transmission for me this time? There was an article saying, so I took a look. I thought I should learn something that is a little difficult (for me).

And the first thing I learned when I started reading about the dual clutch transmission.

Already.

Can I show off my tremendous degree of ignorance? Are you surprised?

While yelling at the blog that I love Porsche so much, I say "Did you really know that again?" Oh, it's embarrassing. No, but this is also a temporary shame.

The fact that I did not know about Porsche is that it is about PDK, which is an automatic transmission developed by Porsche.

The official name of this PDK (I can't say I don't see it ^^) is "Porsche Doppelkupplungsgetriebe" in German ... Yeah, I knew so far.

PDK is an abbreviation for Porsche Doppelkupplung. This is OK.

German meaning of Doppelkupplung

Next is the problem.

What I didn't know. Yes, that means this German word "Porsche Doppelkupplungsgetriebe". A literal translation as a meaning or a word.

This ... Actually, it usually means "Porsche Double Clutch Transmission" in German! !! !! I didn't know! !! !!

Because I thought that Porsche Doppel Kupplung was a cooler Porsche term that was given as the name of the automatic technology developed by some Porsche, so I did not investigate it. did.

But this was just a "double clutch" in German. It was too surprising.

Oh no, I wonder if I'm surprised by everyone who didn't even know that ^^

But then the Germans would have a conversation about Porsche.

"My Porsche is a manual, but yours is a double clutch, isn't it?"

Is it like talking as a normal word? ?? When it comes to Japanese, this conversation

"My Porsche is a manual, but yours is a PDK, isn't it?"

It's kind of cool, but ... in fact, it's just saying "double clutch".

I was quite surprised, so when I reported it to my husband, I usually said, "In the United States, it's called DCT. It's not just saying dual clutch transmission in English. Isn't it?" The correct theory came back easily ...

That's exactly what it says. DCT is also an abbreviation for dual clutch transmission, which is extremely straightforward.

What is a dual clutch transmission?

For example, these cars are all dual clutch transmissions. ↓

Such a dual clutch transmission (DCT) is a kind of automatic manual transmission (AMT) that has two clutches instead of one.

Transmissions are now the mainstream because they can provide better fuel economy and higher performance than ordinary automatic cars.

Like a normal manual transmission, the AMT has parallel gears and a DCT that removes the transmission from the engine when the gears are shifted to another gear ... that is, the transmission body is odd. Since the gears are divided into gears and even gears and clutches are assigned to each, one clutch is disengaged and the other clutches are also connected, resulting in smooth shifting.

By the way, this series of gear changes is not done by the driver's clutch pedal and shift operation, but by automatic transmission.

… Check here. Did I understand the structure of the dual clutch transmission? No, please don't check that (laughs). Well, somehow ... ^^

In other words, not just one clutch, but two distant clutches are working together.

The PDK gearbox uses a hydraulically actuated wet-clutch pack, with one clutch connected to the "reverse, 1st, 3rd, 5th, 7th" gears. And the other clutch is connected to "2nd, 4th, 6th" (the story at the time of 991).

This was also written in the parable, but if, for example, the PDK (7th gear) was a player of the 7 Olympic relay team, one relay player (1st gear) is about to start. The image is that the next relay player (2nd gear) will gradually increase the speed and start running near the end of his running section, and will be able to hand over the baton without stopping the running acceleration. So that's it.

* However, unlike the relay, in the case of PDK, when the 2nd speed player is running, the baton is prepared so that it can be handed over not only to the next 3rd speed player but also to the 1st speed player.

And, as if to nourish and hydrate relay athletes who need water, the oil-soaked hydraulic wet clutch will not wear out when overheated or under pressure. Haha.

Yeah, I don't seem to understand the difficulty, but I think I managed to understand the movement. … Really (laughs)?

And it seems that this hydraulically operated wet clutch is made so that even if Porsche's PDK starts launch control, the parts will not be damaged.

He said that he would bring the number of revolutions to a high output point and give the maximum torque to the wheel without slipping the clutch and letting the wheel slip.

Ah, I don't understand anymore, so I'm done thinking about difficult things.

I will continue to enjoy Porsche 911 purely ^ ^!
