Can do you make your rear wheel drive vehicle move if one of the rear wheel is net having firm contract with ground?

I understood the basic concept of a U-joint, but had no idea that the output speed wasn't constant. Very interesting. Thanks for the video!

now,,, why the output speed iznt constant?

@yuvrajzala9756

7 жыл бұрын

VontekSRB because the propeller shaft is inclined to transmission shaft, so due to that there will be not the exact transfer of rotating speed or motion. And thus in final drive also the angle will be different hence no constant velocity.

I had trouble as well seeing why but imagine If you push something straight along a line determining it's speed or pushing it at an angle compared to the line. Even if you push it just as hard, you will cover less distance in the initial line's direction and thus your speed will be less in that that direction. Now imagine you zigzag push the object compared to the line. Your relative speed will vary, depend on the angle compared to the line you're pushing along. Regardless of giving a linear, unchanging push on the object. This is the same principle as the constant torque, constant velocity input of the input shaft giving a fluctuating velocity output when the output shaft is at an angle. Resulting in jerky rotation.

so true. im wondering now how a front engined rear wheel driven vehicle can operate so smoothly and the final part of the drivetrain is not jerky.

DangerDaveFreestyle I'm wondering if the rear drive shaft having two U joints gives it the same effect. The front U joint that is up by the yoke to the transmission and the rear u joint going to the rear differential. Does that make a driveshaft a CV (constant velocity) axle without the name?

One thing that should be noted in the last example (double U joint): The input and output shaft have to be parallel for the velocity to remain constant.

The video is exactly what I needed. He didnt just explain the parts and purpose of the U join, like most other videos, but he also talked about the physics

You missed one very important point! The angle of the outputting universal joint must match the angle of the inputting joint. This problem was the source of some vibration concerns with some RWD vehicles and I have seen quite a few "Raise Kits" put on the rear suspensions of cars and trucks that did not take this into consideration. Some of those vehicles shook so violently they would loosen the fillings in your teeth! The concept of the constant velocity joint was used in the 60's and well into the 80's with what was called the "Cardigan Joint' and it had a very short piece of shaft at the front of a lot of driveshafts on GM RWD cars. A bit more complicated than this video showed, it served pretty well to eliminate vibrations caused by angle variations as long as the final output angle to the differential was under 1 degree.

Thank you, I had no idea about the fluctuation in speed etc, especially the last minute was very helpful!

This video has made a huge difference to my understanding of this joint! Along with helping me complete my course work, many thanks.

Excellent video. This is why when reassembling a tail shaft, it is very important that the marks on the slip joint line up, so the angles on each end also match

Such an excellent video I have ever encountered with! It is explained with simple graphs and simple explanations, as well as supported with a simple video, I really enjoyed it, and I am so grateful :)

Awesome work. Please continue the job.

Ooooooo my gosh ....... Never knew that the speed on the output shaft isn’t constant after changing the angle 🤷🏻‍♂️ Thanks a lot dear for uploading this informative video 😊

Thanks, this is amazing....

Thank you for these videos. I, along with many other instructors have been tasked with converting what are normally lab activities to online lessons in a very short period of time. I certainly appreciate your site as a resource of accurate, clearly explained information.

If you look at light-duty 4x4 trucks from decades ago (50s, 60s, and early 70s), the transfer case was tilted down toward the rear to reduce the angle of the U-joints in the rear drive shaft (the shaft with the greatest need for running efficiently), but this increased the angle of the U-joint on the front side of the transfer case. To accommodate that, they tilted the rear (input side) of the front axle downward. This rotation of the axle position away from the position that "looks right" increased the angle of the U-joint at that location so it was a close match to the steep angle of the U-joint at the front of the transfer case. It's a setup that looks very strange if you don't know the reason, and this video explains the reason.

Amazing animation with lovely explanation :)

Don't know why I needed to know this but I now feel empowered.

Many years ago they taught us this at school, when disassembly the shaft always mark the parts and spline with a file so they go back exactly the same, otherwise the Jerky Motion will ruin the drive shaft. Pretty obvious. I hope kids are still taught these basics mechanics
