Siemens VDO eCorner Project:

[mckernanV7]

can anyone tell me how they plan on anchoring the motor stator?

because from this video it almost certainly looks like the motors won't even work. firstly, they have a hub that isn't designed to spin with the wheels, and the break disks are connected to it.

secondly, if it is designed to spin, it still wouldn't work as in this case the motor stator will just be rotating freely, meaning when they put power to it, the stator will spin instead of the outer diametre with the wheels.

[towardsgful]

@mckernanV7

motor body(not output shaft) and stator braket are connected together

and motor body is attached to arm, and arm is attached to chassis (so, they don't rotate)

and stator braket support stator(i mean, the inner parts of in-wheel motor in the video) and they are connected.

and the outer pars of in-wheel motor in video(i think it's wrong, that's just big bearing), rotor is connected to wheel.

[towardsgful]

@towardsgful

motor output shaft passes through brake disk, rotor braket, wheel and bolted together.

(they are rotating when the car is running)

and the brake caliper is supported by stator group. than there's no problem!

[chuckbear1961]

Kinda going back to the old kingpin system with springs very tuff system the steerin motor not a good idea though

[1BlubeTube]

Thats a good idea.

[need1992]

The idea is good but still need more engering i think. The wheels must be standard and not changed and this costs money. And there is another issue, how do they cool the motor? it's not that easy to let pass air through the wheels and there is not much space for a cooling unit since the project revolves around using less space in the car.

[zonaxmd]

Good idea to make more space for the bateries, but Siemens will spend a lot of sources to replace the e-motorsin the wheels - bad roads will do thier job ))

[a1ephzero]

Extremely high unsprung mass is a major issue here, move the motors inboard along the brakes at all four corners and add a dash of electric turbine power generation midship.

[aerodyno]

This is a 5 year old project at a big company. More than likely, the people that worked on it have been promoted and now work in different jobs. It'll take a startup to bring this kind of tech to market. Anyone can make an nice animation, let's see it in a real car.

[keymosaby]

Brilliant Concept - at a stroke, it isolates the vehicle body from road & motor noise, vibration, and harshness ! Maximises total vehicle space available, for minimum vehicle "footprint".

Using large wheel diameter units only, for lower rolling resistance, along with economies of scale, during manufacture, identically engineered units could be incorporated, directly into any vehicle, from "Mini" sized to "Maybach" sized.

Vehicle monitor & control dynamics to be modified by electronic systems.

[Xxcalicondor]

what if one wheel brakes down you will go spining in a circle

[AhmadAboulFarag]

I think this is a very bad idea concideing the road conditions and the different terrain a car goes through also it probably will be subjected to shocks since the suspension system has been bypassed in which case will reduce the life span of the car components. plus it's probably more costly to make two engines instead of one, (two production lines Left and right components) that's my opinion (for the benifit it provides)

[Ali2011mb]

отличное видео

[etmax1]

Also has potentially much higher sprung mass which will worsen dynamic performance. Maybe the answer is to only have the rear wheels driven and concentrate on getting the steering geometry right in the front

[radicalhacker]

OMG is this project designed by Siemens VDO Romania?

[googlePaladin]

Just wait till you hit a pot whole, this drive train will be taking impact at ground zero during each impact

[affluenceclm]

True Free energy devices exist,But there are very powerfull forces that want to supress the technology,Find the real deal, a free energy device at LT-MAGNET-MOTORdotCOM ,Join the revolution!

[AudieMurfy]

lots of lovely unsprung weight...

[theareswhite]

nice project

[215alessio]

you guys should be more worried about there is no connection between the steering wheel and your wheels!

one sensor burned and the car does crazy stuff you no longer control

[garawayfootball51]

make a vid on how to replace this tire? oh yeah... it was too long

[redghost105]

worst time to get a flat is when your only motor is in the wheel

[My55i82]

And I thought the less you had mass without suspension was ideal.

[GT4tube]

will new?

[MeTerryBailey]

huhuirgend jemand lust und laune af bissl cam chat mir ist so öde :(

[heartlessvietboy]

When we use truth in examination, we can build one of the best suspension systems out there.

[lordzkonyx]

What program you used to do this?

[saturnwing]

good think^--^

[gtarbmx]

imagine the vibration put on the in-wheel motor. this can't be good. and the repair cost must be though the roof

[crossdraweb]

I thought the same

[Qiket]

Когда уж это будет по улицам ездить?...

[Blas109109]

hmm,good idea but, a repair would cost a lot if you hit a hole in the road or something that damages the wheels..normally it would cost you only the tyres wheels etc,but here the engine and all...and yeah,the springs seem to be small. could anybody tell me the advantages of an in-wheel engine?

[johnnyht2007]

But it will be so dangerous when the streeting motor have some error on one side. The car will get serious crach.

[abdullaah1000]

oh my.

[Aussie50]

Although the wheels appear to come off easy as usual (for Tire replacement) the over-complexity of the drive unit is bound to fail in the real world!

last thing you want is the DC servo steering motor to fail at 100mph!

[digosantista]

It's used in airbus since A319 until A380... it's safe... It's Impressive, didn't it?

[Aussie50]

It is a very impressive design, I imagine the servo units are well built, as you said they are used on Airbus.

but no manufacturer is immune to problems in electronic systems. especially on cars

[Karl21836]

I think this won´t work because the brakes and the electric engine will produce to much heat and there is no space where it can be colded down

[merasanam]

The springs are way to small... nice idea though, but still useless.

[squishboy1]

this should make changing a tire interesting

[Vicious713]

OOh gawd, why?!

[isaacd101]

how will this effect the handling of the car???

[adsabine1]

Slightly more unsprung weight,

[didib2002]

Yes, but on the animation there is no king pin inclination etc.. it would be unsteerable, besides this suspension would be very unstable since it has no angle variation. The pasted this tech from urban rail cars and subways were this tech exists since decades.

[tigersoup]

this technology was already invented and implement in Japan giving 800hp!

[matt9741399]

When the time finally comes on a large scale, I'm going to have a real hard time convincing myself to get into a car with no mechanical link between the wheels and the steering wheel. Some fly-by-wire I can live with, but not steering! Chances of all this kicking off anytime soon are slim anyway so I won't worry about it too much.

[ericssson]

hydro quebec had this a long time ago

check it on TM4

tata will build cars with TM4 tech

[bando8000]

Very nice visuals.

One problem, however. Unsprung weight. The reduction of which being the main practical purpose of an alloy wheel.

Back to the drawing board, or rather, the graphics app.

[supafastsupra2]

my thoughts exactly.

[tigersoup]

don't you think the german engineers must have given it a real good thought? Leave it to them what works well, will ya?

[bellinivernon]

Exelente ,gracias desde argentina.

[bluanvil1]

I like it because now you can totaly get away from the traditional suspention and have total wheel drive control. All 4 wheels can turn and parallel parking can now become perpendicular parking. U turns can become O turns and lane changes can be parallel moves so the car won't roll when you swerve. 4 wheel steering is real neet for those that have a difficult time in parking lots. You could make an all in one vehical, offroader with rockcrawler susp. + luxuary car all in one!!! Keep it up.Thanx

[yourm0mlikesme]

wow still using springs? what century is this?

[QuantumCarl]

The 21st.

Yeah.

We could use magnetics. It's proven to work, but... not knowing the numbers, the main problems would be power to the EM's or relatively expensive and potentially interfering magnets jacking up prices...

[JGMagoo]

The reason there are NO In-Wheel electric motors in ANY car today is simple. The amount of un-sprung weight would make the thing ride like a beast on a rough road. It works fine in railroad trains and huge low-speed earth-movers where it has been used for years. But NOT in an automobile.

[MiderTechnicS]

this is a 100 procent correct, i'm an automotive engineer and the non spring mass must be so low if possible.

Toyota did a good job to test this in real life.

[txroyscock]

Fuck you are stupid they have had more than one electric car but the oil company's brought them out and got rid of them its nothing to do with the weight. you can buy an electric car in china right now and they work fine. Do a bit of research before you make shit up

[JGMagoo]

Step 1: Learn to punctuate and construct sentences for better communication skills.

Step 2: Read my post. I said nothing against electric cars. Just that I thought in-wheel drive motors would cause a ride problem.

Step 3: Move to China and buy your car there.

[sausageslaps]

and how does ths system deal with mud, dirt and other contaminents? electric motors of this day require a rather clean enviroment. a perfect answer in a perfect world

[ff9zidane199]

lol oil companies r gonan be pissed but hey they can still sell oil to factories and and other heavy hardwear material industries

[justgotbackfromnam]

Siemens seems to be under investigation for a tax haven issue.

[nicktumi]

uh what if they turniing mechanism becomes off balance then u have your tires going in different directions. that cant be safe. how would the directional alignment always be correct?? I would love to see this as the future design but safty first right?

[JustMakingComments]

Easiest way to convert normal cars to electric. The oil company will just destroy this project.

[larsandretarte]

Im working @siemens VDO in Switzerland. Now Continental Bought VDO for 11,4 Bio. EURO

[msarb]

Siemens VDO is gone as of today. It has been aquired by Continental Corporation. We'll see what the future will bring...

[avarlives]

great... but what happens when you drive though a puddle of muddy water?

[jeffsadowski]

Valid concern. But I don't see how it would be much worse than what happens with your current brakes and bearings when you do the same thing. You can have sufficient shielding.

[QuantumCarl]

Remember the engine part that's in there?

[colibridelapampa]

FANTASTICO!!!!

[RenewableEnergyZone]

Some good ideas. The last part is kinda sad. Robots are putting the wheels on the cars. Remember when we had people do those jobs.

[jeffsadowski]

Now we have human overlords to control and monitor the robots :-P

[QuantumCarl]

Yeah, remember when every white man had a black slave?

I'm thirsty, but lazy! D:

[jackkrap]

That's not it. The car models are based on Audi models, but if they were to leave them as Audis, they'd get into trouble with their legal department, so they have to alter them enough for them to be unrecognizable.

Of course, I'm sure the models themselves were legitimately acquired, but they can't have the animation imply that this is an Audi-involved project.

[bornman88]

Great Idea!!

[wyetuck88]

maintenance will be a big problem

[sentra75]

chevy

[NJmalibu313]

The government still wants its gas money! Also, why the need for a hood/firewall/engine compartment?Couldnt that space just be used for more interior room?

[QuantumCarl]

People don't like what they're not used to.

Plus, it's all about structure. It adds strength and crash resistance. If you look, people are in what looks like a bubble.

[SchizoSystems]

Those germans are the most innovative people alive. And they invent usefull stuff, unlike those eastern guys

[hazbizarai]

Easy boy! Make some research about what's happening in the Russian universities

[SchizoSystems]

They invent Lada there? Come on... Russians may have nice thoughts but they have no quality! "Deutsche Grundlichkeit" remember...

[hazbizarai]

I'm not arguing about the german potential, because is something untouchable. Is about "those eastern guys" ... if you know what i mean

[SchizoSystems]

Yes, I never said russians were stupid or so or other people as well for that matter... It's what you do with the information you recieve after research. And in belgian universities they have some nice "mostly medical" researches too

[hazbizarai]

I'm talking about THOUSANDS of projects and inventions, with no money for further development, inventions that americans buy for a couple hundred dollars.

[SchizoSystems]

that's kinda sad... And it's not like the americans make something good out of it then... Cause their 'equipment' is heavy, but stupid made...

[QuantumCarl]

HEY.

We made the Big Mac, Whopper, and SUPER SIZING.

[SchizoSystems]

And that's a good thing?

[QuantumCarl]

I don't know, I'm Canadian.

We're like watered down Americans.

[mixmasterlees]

canadians make great bacon :D

[QuantumCarl]

Maple Syrup, too! :D

[focusboyfocus]

Why are they still using disc brakes?. They should be using the induction power inverted of the electric motor to stop the car, like my juice extractor, man that's power. Or it could still carry de disc brakes but as a backup system, in case the elecs fail. Imagina, charging your batteries while braking.

[hempev]

Not too much charging - regen recovers 5-10% of the energy used, less on the freeway, more in stop-and-go. You could get almost as much return if traffic levels allowed you to coast to a stop!

[focusboyfocus]

oh I see. um, but still it will have power to stop the car right. Imagine, not changing disc and rotors ever again.

[a1120183]

Sooooooooo your not going to be wanting to hit any gutters then yeah

[mechanisma22]

Wheel hubs are cool and where are our production electric cars, oh yeah  batteries aren't quite there yet. I'll wait...

[terrorist420x]

To transfer power and torque, it still requires modification of the hub(gear reduction), difficult to protect from damage due to rain, wind, dirt, vibration, ect., and it probably requires integration with the braking system. Then there's the problem with having a shitload of unsprung weight.

I prefer a simpler setup. One motor, hooked to a single reduction ratio. For a performance car, one motor and a two-speed transmission with one gear for 0-80 mph and the other for 0-130+ mph.
