    Many many thanks to both of you. I landed upon this video completely by chance (was looking for Prius inverter related videos), and I am thrilled that I did. The final bit where you put all the components together, and talked us through how MG1 and MG2 synchronize and drive the wheels either via battery power or via IC engine power was fantastic as well. I have always believed that opening up a machine is the best way to gauge quality, I think I now consider myself better informed about Toyota's hybrid drive systems thanks to this video.

    Great video guys. There are a lot of so-called auto enthusiasts out there who have, for some insane reason, convinced themselves that hybrids are impossibly complex, unserviceable, frail, an affront to god, a harbinger of the apocalypse, etc. I wish I could force them all to watch your video, because from a maintenance standpoint, this is no more complicated than a conventional hydraulic automatic transmission - and as you guys mention, the Toyota HSD power-split drive is practically bulletproof. I've been in Camry Hybrid NYC taxis with 400k+ miles on them. They're incredibly durable cars.

      +doctor zaius It looks SIMPLER than a conventional hydraulic automatic transmission - at least mechanically. I'm wondering about the computer control box which reads the 2 shaft speed sensors and decides when to start the engine, how much juice to give to M2 to control its speed, etc.

      +Theodore Zuckerman It is. As a gearhead and embedded systems engineer, I see this video and want to go pillage priuses for fun brushless DC motor parts at the junkyard. I guess I might do that Sunday, actually...
      Anyone know if the motor-generators are bathed in transmission fluid, coolant, or neither? I'm guessing ATF or air since I see no coolant deposits, but I couldn't tell for sure.

  • @SoHighIFly

    @ 15:30 another reason why it doesnt run is because its "poling" without the rear bearing being located and the air gap being small, the rotor is being pulled by the magnetic field over to the stator

  • @circusboy90210
    @circusboy90210 12 лет назад

    20:03 hpm magnetic motors also suffer less from heat & generate less heat on start up, and also use much less intitial inductive load which keeps the heat down & lengthens the life of the motor they also weigh much less .

    IF you are going to work on cast aluminum on the ground, lay something soft down before placing a mating surface face down. Cast aluminum gouges and scrapes easily and mating surfaces are machined. Please do not do what they did and place it directly on concrete if you run into a corroded bolt and accidently turn the whole thing you could destroy the surface causing premature failure of parts and or leaks.

      Yes, great video. I really enjoyed watching this as an owner of a Lexus RX400h with basically the exact same HSD system. A few pieces of advice to go along with what Mishale said though. I definitely agree with her about the gearbox 100% but another thing. The metal tools as well should not be used on any machined mating surfaces, especially soft aluminum. No metal hammers to pop out gears either. They make hard plastic wedges and special plastic tools for that, plastic hammers to bang on the wedges and gears.

    You guys are great mechanics. I did Prius inverter projects in 2010 but mainly on electrical part. Thanks for showing us what's inside a Prius motor assembly. By the way, you guys suck in electronics. Those are not AC motors. They are DC brushless motors which has to be controlled by sensing what rotor position is. The inverter fires DC pulses to the stater just a bit ahead of the rotor magnet position. If you apply AC like you did on this brushless DC motor, it will rotate forward and backward at the frequency of your AC source.

Before the car stopped me, it was rattling and making knocking sound on at slow moving speed when the HV battery is charging only. If the Mg1 stop charging the HV battery the rattling noise stops.

    Hello guys. Thanks a lot for this video. Please do you have a tear down video of the 3rd generation gearbox? I bought a brand new Prius 3rd gen. from the US and shipped to Nigeria where I live. It started rattling almost from the very beginning. Initially I thought some objects had fallen into the fans but after a careful check I found nothing outside. Prius is not sold in Nigeria and I didn't want it completely damaged by quacks.
    I strongly suspect something wrong with the transaxle . I am a mechanic. I have checked inside the engine with a borescope and found nothing. I have changed the IGR and also chucked the intake manifold; both are pristine clean as the vehicle has done only 17000 miles in all. The car has been grounded for a year as the rattling got out of control and the Check Hybrid System won't let it engage the drive or neutral. It quakes heavily on starting and practically shuts down immediately with a warning to check hybrid system.
    Please I appreciate any advice. I couldn't get the service manual to buy.

  • @64davrecon

    Great Video, Thanks for posting!
    One question I have about the transmission's operation that I just can't wrap my head around, is - Is there any kind of physical or mechanical brake on the rotation of the MG1 (the smaller one)?
    That power split device looks very much like an open diff.
    It seems like there's a lot of opportunity for power to spill out the back of the transmission (thru MG1) when the ICE and the main motor MG2 are turning at full torque, much like when you lift one wheel of an open differential off the ground and that unloaded wheel spins up uncontrollably. How do they stop that?

    • @kenstein
      @kenstein 9 лет назад +1

      +64davrecon I'm honestly not sure, but you can use a brushless motor as somewhat of a brake - you just shunt the windings all to ground and it becomes an eddy current brake, effectively. It won't completely stop the shaft, there will be some slippage, but it will bring it nearly to a halt, which is good enough in this case. If you want peak efficiency you could even put that power into charging the battery to apply reaction force to the MG1 rotor instead of just shunting it to ground.

    Hi Guys, Great Vid! I have a question about how the ATF gets into and all over the internal parts: I did not see any seals to contain the ATF in the gears so I am assuming it goes all over the place in the trans too. So does the ATF get all over the electric parts too? And doesnt that make a bit of a electrical shorting hazard as the ATF gets old/carries metal dust and breaks down? I also suspect that high freq high voltage would have little problem finding an electrical path through the ATF, especially when it is full of metal dust from the gears wearing over time. Any thoughts on this? Thanks.

    Wish the title of the video said what year/gen this was. Would save people a lot of time without having to watch to find out..

    Enjoyed the video...very informative. Where you able to reassemble correctly...lol? It's amazing the degree of reliability Toyota has acheived with these beasts...so much stuff going on in the HSD.

    So did you replace the bearing that had a gritty sound? If so did it fix the issue? I noticed something almost immediately after you split the cases, the "Chain" from the trans-axle to the final drive assembly was solid as a board! Drive chains are supposed to be loose and freely movable. Gen 2 used "Chain" drive, Gen 3 went to "Gear" drive. I bet that's why Toyota changed that design. From all the over comments doesn't look like anyone else noticed.
