    The high/low is for all wheels. It's essentially like using a lower gear in the transmission.

  • @EngineeringExplained
    @EngineeringExplained  11 лет назад +1

    It of course, depends on the application. Open is fine for everyday cars. An LSD is beneficial in many applications such as racing, or even towing. Locked diffs are great off road, but terrible on the road.

  • @EngineeringExplained
    @EngineeringExplained  12 лет назад +2

    The lower gear set is for high torque low wheel speed. The high gear selector (which your car is usually in) can't gear down this low, even in 1st/2nd. Now you could use second gear high for something like going down a mountain where you don't want to overheat your brakes.

    I used one called shigley's mechanical engineering design. It's great for the design of things, such as chains, clutches, flywheels, etc..

    I was not having a single idea of how a transfer case works. Infact i didnt know what is it for. But in 10 mins you made me understand working of every single part of a transfer case.
    Great Job! Thank you!

    @djcarkhuff 10 лет назад +15

    Your videos are very informative and nicely explained with the white board! It's a nice learning tool for beginners or even a refresher for those familiar with the systems. Great work!

  • @EngineeringExplained
    @EngineeringExplained  12 лет назад +1

    It could be incorporated into the transmission. Not entirely sure for the reasoning, but if it's not, it allows you to use the same transmission across multiple platforms, making the transmission more versatile rather than for just 4WD vehicles.

  • @EngineeringExplained
    @EngineeringExplained  11 лет назад +1

    If it's a setup with 2WD and 4 wheel drive, using a transfer case, there wouldn't be a center diff. Center diffs are used in AWD vehicles to balance the power/speed distribution from front to back, rather than a "locked" set-up as shown in this video.

    The first time I couldn't follow a thing. I paused for a while, watched the sketch u drew. And the second time I saw the video it all made sense.... thanks alot for the video.....couldnt ask for for a better tutor

  • @EngineeringExplained
    @EngineeringExplained  12 лет назад +2

    There's a selector for it. Yes, you can be in drive (D) in low gear (L), or in second (2) and low gear (L).

    Pause 2:01 if you don't know what a drive shaft is look for a video explaining... Great video man. Just as a heads up you can drive a 4wd vehicle with no trans fluid in the transfer case. It just won't go in to 4wd or on an AWD vehicle it won't engage the front wheels when they slip.. please continue.

    I've been watching your videos for some time , you are doing a really good job explaining different systems in Automobiles
    I just have one question : How about the red gear ( that is connected to the front shaft ), Does it rotate on bearing, while the 2WD is activated ?
    Am really thankful for your hard work
    keep it up..

    • @EngineeringExplained
      @EngineeringExplained  11 лет назад +3

      Glad you enjoy the videos! Yes, the red gear would rotate on bearings, as would the other shafts as well to minimize friction.

    I’ve been thinking about something. Would it be possible to have a FWD, RWD, and 4x4 transfer case on pickup trucks? FWD would be great for driving in rain and snow without weight in the bed, but you still need the RWD for towing, and 4x4 would still be wanted by most. With the geometry of the transfer case, would it be possible to have all 3 of these drive types?

  • @DaveWildey

    really good job explaining this. I have tried to explain this to my kids and NEVER could....you did it.

  • @EngineeringExplained
    @EngineeringExplained  11 лет назад +1

    Yes, some do the opposite. I know the Golf R disconnects the rear axle on highways (completely different system, but you get the idea).

  • @domls1317
    @domls1317 Год назад +1

    Can you safely tow a 4WD on all 4 wheels by just disconnecting the drive shaft? Will the transmission still spin if the cv axles are still attached? Or would you have to also disconnect the front cv axles?

  • @EngineeringExplained
    @EngineeringExplained  12 лет назад +1

    They will spin at the same rate, though if you wanted to make things complicated you could use a different gear ratio diff at the front to make up for a different gear ratio in the transfer case. Probably not the easiest solution though, 1:1 should be used in the transfer case. The model in the top left isn't the most accurate drawing. :)

    @whitleyca 12 лет назад

    FANTASTIC videos! Just bought 1st 4x4 (01 Silverado) and your videos have really helped me understand how they work. Very clear, easy to understand. Keep up the great work!
    I am curious - PT 4x4 - Is the transfer case "engaged" when driving in 2wd? If the chain in the case were to break/snap, I understand they stretch/wear over time and use, would I be walking? It seems that when in 2wd, power simply passes through the case to the rear. Not that simple?
    I appreciate your input.

  • @EngineeringExplained
    @EngineeringExplained  12 лет назад +1

    Tell me about it. If there was a better way I would try to do it. But it doesn't seem time effective to make 3D models, and I won't use copyright images so that makes it a little difficult. My girlfriend hasn't watched a single one of my videos all the way through, she also becomes quite bored. How supportive, right? Oh well, I try to explain a lot of it to her anyways.

  • @EngineeringExplained

  • @Islander39er
    @Islander39er 12 лет назад

    yeah thanks man, thats why i was wondering since the wheels obviously have to spin at the same (or maybe similar with a differential..) and i was wondering what happens there since i haven't myself had an opportunity to see the inside of one. figured it would then have to be 1:1. well thanks man, looking forward to the next video!

  • @Leonakamrluver
    @Leonakamrluver 11 лет назад

    Thanks for your response. Reasons for my question, is that my 4x4 has an open differential at the rear, and going offroading is a bit of a pain, so i was wondering to replace the rear diff with an LSD or E-LSD.

  • @EngineeringExplained
    @EngineeringExplained  11 лет назад +1

    Hmm, so it doesn't work anymore? Sounds like transfer case as the transmission would likely stay in the same gear.

    as it happened before. each and every thimg becomes clear
    and one more thing mate, i may be wrong but i guess there is a small mistake in your diagram. in 3 section the blue coupling may be connected to the green shaft and allow to enable to wheel drive and when we shift it , it will connect both ie front and rear axle

I look forward to your thoughts, thanks again.

    Is it possible you could explain how a dual transfer case set up would work in one of your videos? ive learnt alot from what you have posted and have always been curious about that

    • @GregoryPointing
      @GregoryPointing 9 лет назад

      +Charlotte Gibson Dual transfer case is just another set of reduction gears at the front. Looking at the video if you add another set of the red reduction gears between the engine input shaft at the green main shaft you have a dual transfer case.
      The part where it gets confusing is the 4wd selection part, which you only have 1. The transfer case and 4WD selection are 2 separate things and you can have multiple range selection. Atlas make a custom 3 speed transfer case (as an example) that has 2H, 4H, 2L, 4L and 2L(2) and 4L(2).

    you are obvious ly a brilliant engineer, however, if you could find a program that animates the affected parts as you speak that would be so much more helpful. thanks for the videos, keep them coming. by the way, I have a puzzle I am trying to solve on my 1996 Toyota Land Cruiser, which has a full-time 4x4 system. the previous owner took off the front prop shaft to make it a RWD truck for ease of operation on dry surfaces. I would like to reattach the prop shaft to get 4x4 functionality but I notice that the output flange on the front diff spins freely Wight th prop shaft off. is this normal or shoul the front diff be locked in place? I look forward to your thoughts. thanks.

    @aaronrobbins1458 7 лет назад +1

    Hi, I've got an AWD 1997 Chevy Astro. I'm pretty sure one of the front axles broke, so now I'm driving in 2wd RWD. My question has to do with something my mechanic said. It was my understanding that if there were a broken axle, or any other reason one wheel was not touching the ground, all of the torque would go to that wheel/axle, escaping through the path of least resistance. So, I figured that since I was able to still drive, that my transfer case must be working, locking up to ensure that torque goes to the rear axle. My mechanic is saying that the transfer case might be the entire problem, and that if the viscous coupler were to stop working, power would go to the rear axle, but be unable to transfer power to the front axle. Do you know which it is on my vehicle? Does this transfer case always give power to the rear axle and only give power to the front axle when slip occurs, or is it more like a standard differential, where it sends power in both directions all the time, but locks up when power try's to escape one direction or an other? Does my question make sense?

  • @toddadamsaz
    @toddadamsaz 10 лет назад

    Thanks for this video. I'm thinking with your explanation and another video here that I can rebuild my transfer case. It's an older 2001 X5 BMR and it makes a noise when you take your foot off the pedal. It's AWD but sound like a old 4WD coming down off acceleration. Sounds fine normal driving but when your foot comes off the pedal it starts a 4WD gear wine. Not sure how to explain but sounds normal if you've had old 4 wheel drive truck. Right now not sure if it's the transfer case or the transmission but took it to an BMR mech and he could not decide either. Will get it diagnosed and pay the $100 so dollars @ BMR and hope to take this challenge to my garage. That being said thanks for your video and I have a better understanding about the transfer case and think that is the real issue. Will update you when I find out.

  • @Islander39er
    @Islander39er 12 лет назад

    thanks man great video, one question:the gear driving the front driveshaft/axle seems to be smaller than the one hooked up to the rear shaft/axle. is this actually like that? seems like the ratio would spin the front axle way faster than the back axle...

  • @xI2aiizza
    @xI2aiizza 8 лет назад
