EsDesigns' New EV Driveline

All talk....no show

AXLETECH REVEALS ELECTRIC INDEPENDENT SUSPENSION CONCEPT AT EUROSATORY 2018

..."Troy, Michigan, June 11, 2018 – AxleTech is combining its expertise in electric vehicle powertrain systems and independent suspension technologies to develop a next-generation 5000 Series Electric Independent Suspension Axle System concept. The eISAS™, as it is known, was unveiled at Eurosatory 2018, the largest international defense and security exhibition, in Paris, France. "...

...seems everybody and his brother has some new high tech electric drivetrain...but I'm thinking everybody needs to get in line behind Elon...

"but I'm thinking everybody needs to get in line behind Elon..."

Yes, but you wouldn't know.

Don't get your wings burnt, Phoenix was lucky.

Talk is cheap....I don't have to know anything at all, I can see....and I see you have bold claims with no sales, no product, nothing to show at all....I was born of the Sun, it harms me not....

Its pretty hard to beat the Nissan Leaf drive system, for simplicity.

It 'was' pretty hard ..........

So we can appreciate it when we get it, what cars will it be in?

When do you expect it to appear on the roads?

What does NVH stand for?

Hard to say, most companies are very reluctant to sign NDAs. Ford advised me to set up a car company - we are doing that now.

We have finished the first prototype driveline; a 'proof of principle'. However, I realized I could substantially increase the torque capacity, with a relatively minor design modification. That is currently under way, then we will fit it to a vehicle. First vehicles to use it will be a particular DIY EV conversion that will benefit most from this design. Say 1Q/2Q 019.

Then, some lower volume production vehicles including city cars. We can supply full drivelines to 'drop in', for some manufacturers; we may exchange drivelines for bodies, & do Asian production here. The 'Detroit of Asia' is about 1/2 an hour away.

Following that we expect to have the interest of the majors; some vehicles will readily accept the driveline, others will need a degree of redesign to suit it.

But all will benefit substantially.

Tho I am concerned that some parties might get bad advice from their counsel; I have seen this before. That is why I mark my inventions 'Patented by Smith and Wesson'

What does NVH stand for?

Noise Vibration and Harshness; generally a subjective measure of how smooth & quiet a vehicle (and driveline) is. Jaguar is 'up there', any Yugos still on the road would be at the other end of the scale.

In the evolution of EV's the next major drive revision will be the wheel motor. or so said the pundit.

Right now the technology is getting smaller and more powerful everyday. Think drones. The "Gold standard" for EV's is not Tesla. (Yes I actually said that) They are just the most successful at it so far. Elon's goal was never to be "the" car company but to spur the development and adoption with one mighty shove. It takes someone with a shit-ton of money and the willingness to bet it all to make it in our screwed up economics system. It should not be that way. It stifles innovation and advancement.

There are 5 variations (so far) on our basic design.

Each one is better than wheel motors.

I am not doubting you on that. I was just repeating what some "expert" said that I happen to agree with. What you have, and everyone else has, is basically the same design that was used at the turn of the 20th century. Batteries and motors have gotten much better making it a practical possibility, but real innovation and R&D will come from a different line of thinking, like it always does. Once someone decides to put out the money to do it.

How do you know what I have?

Hey Stuart, remember that wallaby you saw last week?

I have no idea what you've got, but I have probably been vaccinated against it.

No criticism of your endeavor intended, just sharing an observation that I happen to agree with based on my experience in racing.

There is a first time for everything, Rash

Then there are variations on those variations, such as traction control, eg our Noµ LSD, and torque vectoring.

Am I right, or am I correct in stating that the aim of all powered vehicles wherein the power is directed through the wheels, is to keep the unsprung weight to a minimum.

Why, therefore even consider putting the motors in the wheel? That is a solution being misplaced.

Have the individual motors inboard, out of the muck of the road, and deliver the power via simple articulated drive shafts.

"keep the unsprung weight to a minimum"

Generally, that is correct. However, some vehicles are less sensitive to unsprung weight / sprung weight ratio than others. e.g. For a city car / urban transport moving at low to medium speeds on good surfaces, unsprung weight is not much of a problem, so inwheel motors can be used. Ballon tyres at a lower pressure can often compensate here.

For off road vehicles, it is a problem when for instance the weight of a live axle can be about the same as the weight of the sprung rear end of a vehicle, & 'the pair' can resonate, say over corrugated roads. Very uncomfortable for everybody!

Our new EV driveline, in 4 of the 5 versions, has the absolute least mass, and absolute least unsprung weight, of any driveline. When you see it (& if) I can show how it could effectively be considered to have 'negative mass'.

Unsprung weight is one thing (and for off-road vehicles the low centre of gravity of wheel motors may be an advantage, but only in theory), the vibration would be the principal factor ruling out wheel motors. Getting motors to tolerate road vibrations would be nigh-on impossible - I am thinking of cobbled roads here. Fat tyres to reduce vibration would lead to poor handling.

Ferdinand Porsche's first car was a four-wheel drive wheel-motored electric vehicle, and I suspect that is where they will remain - in history books.
