This is a very basic question. I understand that the torque is passed from the engine onto the transmission via the flywheel in manual transmission or flexplate in case of automatic. The transmission converts the input torque to an gear who size corresponds to the current vehicle movement. What I do not understand is how the processed torque output of the transmission gets passed onto the differential, which I understand is the ultimate conveyor of power to the wheels.

Please correct any possibly incorrect assumptions above.

  • There's a shaft with a universal joint.... hold please – Alec Teal Sep 11 '15 at 20:18
  • in the case of my Tacoma., i see that shaft only going to the rear wheels, not the front differential. – amphibient Sep 11 '15 at 20:19
  • Then it is rear wheeled drive. – Alec Teal Sep 11 '15 at 20:19
  • it's front wheel drive with 4WD optional – amphibient Sep 11 '15 at 20:20
  • There's a box.... grr what's it's name. Basically there's this box and it has 2 rubber bands in it (proper rubber not like desk rubber bands) with like a thick part and a thin part. They transmit power down.... hold again please. – Alec Teal Sep 11 '15 at 20:21

This system is called the drive train: enter image description here The shaft I was talking about was the prop-shaft. How I forgot that I don't know.

If your car is allwheel drive or can be it'll have something called (unimaginatively and again, I don't know how I forgot this) a 'transfer box'

  • The image you show is a very atypical drive train. Most vehicles do not have a transfer case. Even most vehicles with a transfer case are not setup this way. A very stange setup to say the least. And now I think I know why, this is originally from a Russian (or other Slavic) speaking country. That's why it's Bass Ackawards. – Pᴀᴜʟsᴛᴇʀ2 Sep 12 '15 at 21:35
  • @Paulster2 it was the first image on the search I did. I am happy to find another but the thing is even on other cars, it will not vary too much – Alec Teal Sep 12 '15 at 21:54
  • It's not a huge issue. It's just when a picture tells a thousand words, you don't want the words your image is telling to be the wrong ones. – Pᴀᴜʟsᴛᴇʀ2 Sep 12 '15 at 22:09
