Basic knowledge of automobiles (10) What can be seen in the gearbox model
Maybe the cardholders who pay more attention to me will notice
Follow the previous progress
In this issue, we were going to continue to talk about the driving system of automobiles
But.. But
It occurred to me that I had an idea
The previous issue of the gearbox
There is a very useful knowledge point that I forgot to share with you
So this issue
We'll have to turn back for a while
Don't mind, everyone
I'm not a casual person though
But.. I'm not human
Saying
When you look at the model diagram in the truck house
It's often seen
Here's what we'll say about the chassis:
"
The car was powered by an engine with model XXXX...... It is paired with a gearbox with the model XXXX...... (A few words omitted here)
"
About the meaning of the engine model
If you don't understand, you can
But this article
I don't want him to be a "transmission model dictionary"
I want to tell you
A trick
The model of the gearbox
Actually, it's the same as the name
In order to distinguish it
What do we usually rely on to distinguish gearboxes?
What brand?
How many forward gears?
Is the top gear direct or overdrive?
Is there a synchronizer?
In the transmission model, it is nothing more than these few points of information
Let's just guess what is easy to judge
The best guess is, obviously-
Number of gears
Just guess wildly
Leave it alone for now
Take a chestnut
10JS160
I ask you, how many gears does this transmission fluid have?
Let's use the elimination method
First of all, certainly not 160
(What?) I let you guess? Then you can't guess 160)
That's obviously 10
That rest of the JS
The representative is actually Fast
By the way, I will tell you all
The code name of several gearboxes is common
Fast : JS
(Actually, J stands for mechanical; S stands for double intermediate shaft. But generally only the Fast model will have these two letters)
FAW Jiefang: CA
Sinotruk: HW
Wan Liyang: WLY
Okay, okay, it's not a dictionary
No more enumerations
The brand and gear number are there
Then the basic information of this gearbox has been understood
The meeting was adjourned
Well, know you're not addicted
These two know later
What many people want to know is:
The highest gear of this transmission is overdrive or direct
Here's a tip: ask Baidu
Wait, don't go
Of course I wouldn't be so perfunctory
Note:
The following content involves industry passwords
I'm risking it to you right now
You must remember that you can't betray me
!!!
For the common heavy-duty gearboxes of Fast and Sinotruk:
T stands for synchronizer
L stands for aluminum shell
And Fast A and B, Sinotruk's C, and Jiefang's X
It stands for overdrive
Of course, these passwords are only suitable for everyone to make a preliminary judgment
The actual configuration of the gearbox still needs to be confirmed again with the dealer
And then
In addition to the following information
The remaining letters, numbers
It may be that it is
Maximum torque, serial number, etc
Relatively speaking, it's not that important (just relatively speaking)
Ok ok
The secret is also over
Let me go
