Good observation.

My power steering went out and I can't drive.

Is there a full moon out?

I think one of you guys left this guy in a ZL1 thread... seems you need him back now..

I tend to leave him all over this place..... sorry.

Off topic.....

To all in the "house" if you get a chance please stop by this thread. This guy is involved in some really great causes.

It appears #3's A4 uses the same steering and supplier as the ZL1

Quieter, smaller, more efficient

In the differential steering systems currently known on the market, which were also developed by ebm-papst together with ZF Lenksysteme GmbH, the electric motor had to be designed to cope with high environmental influences. Its unprotected installation location in the engine compartment, in close proximity to the front axle, subjected it to dusty heat, perishing cold or dampness as well as aggressive fluids: from screenwash through brake fluid right up to battery.

On the A4, though, the drive sits in the column directly behind the steering wheel as an integral component of the steering column. In this design, the steering shaft is routed right through the electric motor and therefore provides several advantages at the same time: it is protected from climatic influences and can be installed universally as opposed to previous solutions dependent upon the space available in the engine compartment.

The innovative trick opened up a whole series of new hurdles that the developers in St. Georgen, at ZF Lenksysteme and Audi had to tackle. The requirements changed due to the fact that the motor was moved into the passenger compartment. Of course it no longer had to be sealed, but it now had to be quieter, smaller and more efficient. The basis for development was therefore offered by a new EC motor design with a high power density optimised for the installation space. The brushless electric motor stood out from the outset through its low noise level at top working speed. Furthermore, it lasts throughout an entire vehicle life — and its energy efficiency is unrivalled. This innovative technology allowed drive integration in the steering column. It would not have been possible to have realised this system and the enormous power density with conventional electric motor systems.

The requirements constantly increased during the development phase. According to Thomas Schrag, sales support manager at ebm-papst St. Georgen, the initial motor was completely different than the one finally used. “We had very little room available anyway, and because of the crash specifications the EC drive for the dynamic steering has now become very short — one millimetre less space and it would have had to be built very differently.” The solution worked out by the engineers can not only no longer be heard, it is also unnoticeable that a drive is working in the steering column. “The motor now has an absolute minimised detent torque, no torque ripple can be felt on the steering wheel, (torque fluctuations whilst the steering wheel is being turned and the electric motor is working). Our developers sat for months working on a solution to this problem”, recalls Schrag.

Despite the secret helper, the driver always has direct contact to the front wheels via the steering wheel, which is also a legal requirement. The driver always has full control, even in the unlikely event that the motor for the differential steering system should fail. The intelligent technology now puts every manoeuvre to the test wherever driver error was frequently the cause of accidents to date. This is how the system helps in achieving extra driving stability and comfort – and therefore greater joy at driving.

The heart of the power steering

The mechanism of the dynamic steering system, the actuator, is integrated directly into the steering column. It consists of an EC motor with position sensors, an interactive gearbox and a lock to secure the motor into a motionless position. The Harmonic Drive gearbox ensures that both the manual pulses from the steering wheel and those from the EC motor are transmitted to the steering gear of the front axle. The interactive gearbox works almost clearance-free and with great efficiency. The motor itself, as a load-bearing element, is a component of the steering column, the steering axle passes axially through the motor.

Yup... and the guy posting GM Fail is the same one saying it was only a piece of paper 2 months ago.

Touche.... the topic is always changing around here.

Regarding the PS issue, He's probably part of the video game generation. Strong thumbs, but no arm strength.
