Siemens VDO eCorner Project:

Siemens VDO engineers are working on plans to integrate the drivetrain, steering, shock absorbers and brakes directly into the wheels of future cars. This concept, called eCorner, is the basis for the ecological "Drive-by-Wire" automobiles, which will become a common sight on roads in 15 years. eCorner replaces the conventional wheel suspension with hydraulic shock absorbers, mechanical steering, hydraulic brakes and, above all, conventional internal combustion engines. For car owners, eCorner translates into improved fuel mileage, more safety and greater convenience. eCorner provides designers with all new freedom to create future cars with an electric drivetrain and electronic control.

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.

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.

@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!

@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.

[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.

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.
