Creative SpoonFeeding- Techniques To Learn Automobile Easy!

Some things have to be rote-learned, even after heavy dosage of understanding. More so with the subject of Automobile, with diagrams popping up in every question. That's a boon actually, I'll tell you how as we move on.
So what I'll try doing here is lighten that understanding dosage, and make you rote while you note! Join the fun!

Synchromesh Gear Box-

First, let us rote the diagram. Yes, ROTE. Believe me, it'll take you maximum 5 minutes, and you'll never forget it throughout your life.

Step 1: As shown in figure, first draw a shaft, and two cursor-shaped things facing each other on either side of the shaft.100_2675

The shaded portion on the shaft is the SPLEEN.

Step 2: Link the cursor-like things to the spleen, and draw a box covering the spleen.
100_2679

Step 3: Now make the outer body for the same, and while doing so, make sure that you don't omit the DOG TEETH(The bumps right beside the cursors), and note that they lie on a bigger shaft(The CLUTCH SHAFT).
100_2681

Step 4: Do the same on the other side too, and once done, shade each part to differentiate from each other. Also, draw a similar figure again on the right side (I've left it incomplete since the figures are identical)
100_2683

Step 5: Then draw a lay shaft below the entire diagram as shown, and add the connecting gears. 100_2684

Step 6: The FINAL Diagram-
100_2686
The Dog Teeth has been highlighted. The Cursor like thing has got 2 gears, one with internal teeth, and other with external teeth.
Note that all the gears on main shaft and lay shaft will rotate only when Clutch shaft 'A' rotates.

There, the diagram has been done, just reading the theory once from your book shall be enough now. 😀

Ok, the initial learnings shall be based on diagrams and flowcharts, and pretty soon I'll be sharing out poems of various Q-As, those have helped me immensely, and I'm sure will help you too. Well, I'm of very little use to the sincere students, but the backbenchers and last-minute book shufflers should find this more than sufficient! Ciao! 😀

Single Plate Clutch-

The single plate clutch's schematic diagram is something like this.
clip_image0013

Looks pretty simple, eh? Wait till you are bombarded with hundred other diagrams throughout the book that'll send your brain for a toss. Here's how we make the diagram simpler:
(And I won't be drawing the entire stuff as it takes a lot of time!)

Step 1:
Rotate the image by a 90 degrees as shown.
clip_image0013

Now imagine that the flywheel's a huge field, and three towers(The big one at the center and the smaller ones at either side) stand on the field. Provide some fencing at the smaller towers(those make up for the springs.)

Step 2:
Now, leave a few millimeters above the field, and draw supports for the bigger tower(starting from the smaller towers linearly, and then inclining them from a point) This is your pressure plate.

Now remember, that gap you left earlier, put a clutch plate there.
Note: The clutch plate lies between the flywheel and the pressure plate.

Step 3:
Where the supports end at the bigger tower, start drawing a diametrically larger cylinder, the King's Chamber( the withdrawal sleeve). Note that it has got a clearance above. Once it's done, add a clutch fork to it, and connect it to a pedal via an adjustable link.

Diagram done. Now read the theory once, and smirk! 😉

Fluid Flywheel-

Now, this is a proper schematic diagram of a fluid flywheel:
GB-01e fluid flywheel_2211_big
Step 1:
Rotate the above image by 90 degrees.

Forget the labeling, just focus on the image here-
GB-01e fluid flywheel_2211_big
What I'm seeing here is a pair of the diver's goggles on a badly deformed nose, and the gearbox shaft could be assumed to be the pipe that goes above the surface of water, helping the diver breathe.

Now, all you need to do is make sure that the pipe is properly attached to the nose and that the goggles are screwed firmly at the ends. Theory/Labeling: From your book.

Diagram done! Go, now show-off to your friends whatay genius you are! 😁
6 years ago
I repeat, this is my way of studying/and making others study, which may not go well with *all* the mechanical engineers. I may have made some excellent geniuses turn in their graves, but hell, I'll proceed with whatever's less time consuming and sticks to the memory better. Once the diagram is done, theory is no big deal. That can be done just by looking at the diagram and bluffing a few *sensible* bluffs. Get your basics right, is all I would say! 😀

Centrifugal Clutch:

This is a schematic diagram of the centrifugal clutch:
centri

Note how it resembles this-

815tap1

Yes. A tap.

Now once you've associated the centrifugal clutch to a tap, the diagram goes as follows-
Step 1: Draw a basic frame that *looks* almost like a tap.
100_2689

Once this is done, add up the following boxes to the figure as shown,

100_2690

Add a shaded rod in the middle box. Here-

100_2691

To the shaded rod just added, attach a connecting rod, and to that connecting rod, join a ball as shown:

100_2692

After this, add the springs -

100_2693

Ok, now most of the diagram is finished. Just some last cosmetic touches-

100_2694

Make sure to put the roof "H" above the ball "A".

Diagram done! Easy-Peasy! 😀

Hotch-kiss drive:
This is one of the simplest diagram you'll encounter. Still, let's make it even more simpler.
Keyword here: Kiss

wpg1

Observe how the "Frame" and the "leaf springs" form a lip-like structure around the wheel.

Now the final figure-

100_2696

Note the pencil-marked labeling over the pins. Front-end of the leaf spring is pinned, while the rear end is attached to swinging shackles. Rest of the diagram is as it is easy.

Moving forwards, let's simplify the Propeller shaft!
images
In the above diagram, starting from left, the parts are as follows- Universal Joint, Sliding Joint, Propeller shaft, and again Universal Joint.

Remember U-S-P, and this should do the trick!
Note that both ends are connected to a Universal Joint.

Now look at the Hotchkiss Drive diagram to see one usage of the propeller shaft! 👍

please send me sketches of other mechanisms also ........
which book do i refer for easy and practical understanding of AUTOMOBILE mechanisms? Will going to garage for better understanding make difference?
Waiting for reply from any helpful buddy.
Not considering my ongoing studies seriously making me unable to think practically. I think i have that much of potential to be a mechanical engg. in real manner, but something is forcing me back..I THINK IT IS MY LAZYNESS
But still
Let's see, something will definitely happen...But when and how?

Let's do it the other way round buddy 😀 Just let me know the topics/mechanisms that have you going nuts and we can surely work something out together! 👍

And yes, visiting or working at a garage will definitely lend you a new perspective, but the technology employed now is way too advanced for what we're taught in the books. So I can't say whether they'll land you some more grades, but yes, practically it will be great if you know such stuff!

Differential:A differential mainly helps in transferring torque to the rear wheels in rear wheel drive and specially helps in cornering of four wheelers.
2
Don't mad at the first look of the real photo of differential as many of th automobile textbooks have.A line sketch of a differential is enough to fetch you good marks and it saves a lot of time.A line sketch can be easily drawn and i followed the same steps of Ambarish to teach it by rotating the figure.All you want to know to draw a differential is that "A square faced king was driven by a queen" lets go to the work CEans.
1

Step 1:Rotate the differential
2

Step 2:Ok lets start with the face.First draw the Square faced King
3

Step 3😁rawing of Crown to give the real king look
4

Step 4😁raw the axles both up and down and at the end add wheels .Queen(Pinion) drives the King.
5
Even a king cannot escape his wife.............
Note😁ont miss to draw lines in the face to represent gears.
Just kidding. You had finished your drawing. Post the drawing you want to learn it easy.

I feel so screwed for mechanics: statics and dynamics 😔. My friends are all planning to fail it, just to retake it. But, I dont want to retake it. I am no creep, I actually was
searching for some solution on google, when I ended up on this page.

I did have similar notes on Mechanics and Kinematics. The content's not with me presently, but do let me know the important topics you are dealing with (important both concept-wise and scoring-wise), and I'll see how I can help you. You are definitely not failing this paper!

clip_image0013

Looks pretty simple, eh? Wait till you are bombarded with hundred other diagrams throughout the book that'll send your brain for a toss. Here's how we make the diagram simpler:
(And I won't be drawing the entire stuff as it takes a lot of time!)

Step 1:
Rotate the image by a 90 degrees as shown.
clip_image0013

Now imagine that the flywheel's a huge field, and three towers(The big one at the center and the smaller ones at either side) stand on the field. Provide some fencing at the smaller towers(those make up for the springs.)

Step 2:
Now, leave a few millimeters above the field, and draw supports for the bigger tower(starting from the smaller towers linearly, and then inclining them from a point) This is your pressure plate.

Now remember, that gap you left earlier, put a clutch plate there.
Note: The clutch plate lies between the flywheel and the pressure plate.

Step 3:
Where the supports end at the bigger tower, start drawing a diametrically larger cylinder, the King's Chamber( the withdrawal sleeve). Note that it has got a clearance above. Once it's done, add a clutch fork to it, and connect it to a pedal via an adjustable link.

Diagram done. Now read the theory once, and smirk! 😉
