model of Toyota Hybrid Synergy Drive

[gettingahandle]

save gas... fart in a bottle

[maZZiveAttack]

Ok. How is toyota planning to use the drive? With what fuel source? Can you tell me

[cplai]

@maZZiveAttack The model in this video shows how the transmission in the Prius works. The Blue crank represents the Gasoline Engine, the Orange crank represents the Electric Motor/Generator. The current Prius is a Gasoline/Electric hybrid. However, it is possible to replace the Gasoline engine with an hydrogen engine in the future. But Toyota has no plan to do that yet.

[maZZiveAttack]

Run your car on hydrogen!

[cplai]

@maZZiveAttack The drive train design is quite independent of what fuel to use. The video only shows the transmission. The engine can be modified to run on hydrogen without changing this transmission.

[tdukhovny]

@maZZiveAttack

you say hydrogen, don't you?

four problems with it:

1. where are you going to get hydrogen?

2. are you ready to carry several tanks of VERY EXPLOSIVE GAS at VERY HIGH pressure on your car?

3. where is the infrastructure to fuel cars with your agenda gas?

4. carefully calculate the energy input to get hydrogen -- in order to have the positive energy balance at the end.

othervise, good idea.

good ideas are especially good to pave the road to hell -- someone said that.

[maZZiveAttack]

@tdukhovny Yes. I'm ready. I'd rather be using hydrogen than petrol.

[tdukhovny]

@maZZiveAttack ... still, bro, you have not addressed any problems with the hydrogen fuel. the "rather" approach is only valid if you have the option -- option supported with solid technology. the latter is at this time only a wishful thinking.

here's one -- gratis -- for you: diesel with the hybrid drive. imho, 100 mi/hr possible.

@tdukhovny ooh I can answer these for you..

1. electrolysis of water splits water into its 2 parts Hydrogen 1 part oxygen, you save the H2 and breath the Oxygen.. k?

2. Hydrogen is safer then gasoline because if the tank ever ruptures the hydrogen will convert back to water at a rate higher then full burst rate of the tank. test results at Nasa on the BMW Hydrogen 7.

3 Obviosly water.

4 240 watts per gallon of H2, aprox 3x energy of gasoline.

oh, 35psi H2 turns to liquid.

@maZZiveAttack already am, cheers mate! :-)

[Qwerty48121]

thumbs up if ur here cuz of those freaken commercials

[cplai]

@OMGITSJUSTAVIDEO visit wikipedia (English) and read the article on Hybrid Synergy Drive. If you are a visual person that prefers animation to words, then you can go to the bottom of that page and look for the link labeled "Animation showing how HSD works" The animation shows a 1st Generation Prius, but the HSD design is identical to all Prius.

So it's not a real CVT? I mean it still has a planetary gear set.

[cplai]

@banstaman It depends how you define CVT. If CVT means achieving different gear ratios for different levels of mechanical advantage in a continuous manner then this is NOT CVT because there is only one gear ratio at any speed. If CVT means that you achieve various speeds without that jerking sensation during each transition in the transmission, then this delivers various speed smoothly because it NEVER shift gear. Same gear for all speed, including reverse.

[cyborgtroy]

@OMGITSJUSTAVIDEO - There's a pretty decent explanation on the Wikipedia. I can't remember how it works, but it's somewhat simple.

[hugos31]

la azul representa el motor combustion y la naranja representa el motor electrico, pero ademas en una najada o frenada el eje propulsor puede rejenera corriente en el motor electrico naranja

[hugos31]

very very very  good

[saxenavs]

It does not explain the technology

[SHANGRALAAAA17]

the prius is still a homosexual car

[SKYCAM20196]

This shows that the wheel can be rotated with both gear drives on both directions...Tamiya have just used this on the mini 4x4's wheel assembly that makes the plasma dash motor run more smoothly upon jumps. the wheel base should coordinate with the speed of the motor.

[JDCubed789]

It doesnt do anything!

what a bunch of dumbasses.

All it is is a differential using a planetary gear vs bevel gears.

[cplai]

Perhaps you can use a bevel gears to design your version of the power split device. Instead of one drive shaft to spin two wheels, you can reverse the arrangement, use a gas engine to spin one wheel and use an electric motor to spin another wheel, you controlling power to the two wheels, the shaft will spin with combined power from two power sources and you get a hybrid drive train. I guess these dumbasses found a new use of that do nothing differential. Bevel vs planetary is irrelevant.

type ymmot1956 in search bar and look at mine!

[PIONNEER55]

You could just as easily click your name.

[davebestmusic]

stop touching it.. hahahahaahahahaha

[emforty2]

toyota technology beyond average brains to understand !

no wonder toyota is NOW #1 unseating GM on a bad economy

[phdecora]

uhh it doesnt ook more complicated than an old 3-speed bicycle hub honestly

[GrafKrolock82]

It's the Power split device from the toyota prius; the blue crank is the combustion engine; the orange one is the motor/generator 2, the yellow disc is motor/generator 1; Black = wheels.

[cplai]

I tried my best to explain it in the description area on the right. The model was not correctly done and it could be better. I also put a link there that point to a software simulator of how the whole thing works.

[BRONGOHORST]

WHAT IS THIS?????

Cant understand nothing.Toyota TOY.

[bjhorton2005]

That is wicked, ... WICKED cool.
