Youis  a bugger.

Geo....try using NITRO.

I need every bit of help that's available.

Now that I have learned how to make wine I probably won't post as frequently.

These fotos are from prior shoots.

The first foto shows some of the very limited Dzuz fastners in the car. These attach the chute canister to the chassis.

The always present vise grips hold the skin section to the buck. This is at the mounting point of the air brake.

Back side view.

Sorry for the long delay. I'll be with Marlo this weekend and will post an interview within the next week.

While we were at the Gas Up, Marlo told me that the entire front drive unit, excluding the differential, was being reengineered and manufactured. That will include new axles and the steering knuckles, hubs and spindles. He is supposed to receive the engineering drawings and specifications this week and they will discuss any changes that are needed. This change started when the 6000 RPM wheel speed was related to the joint that is necessary to allow steering thru the driven wheels. A serious concern developed to the ability to keep the joint flexible at that RPM and not bind the steering.

He figures one month will be the manufacturing time.


Thanks for your interest.

When do they plan on running the car for the first time at Bonneville?
What a magnificent piece of workmanship!!!

New technology has brought us to re-evaluate the front end of the streamliner. Porsche joints were initially used but the speeds for which they were designed is much lower than this car's needs. It is possible that the heavy balls could bind and lock the joint. It would then be impossible to steer the car.

Mark Williams, in Colorado, has now refined the Greek coupler to allow constant lubrication and an angle of up to 10 degrees for steering, and still remain flexible at a speed that will allow 550+ MPH. ( 6000 Wheel RPM) This guarantees steering with the gear ratios that are available in an application matching the need of the Treit liner.

The axles to which these couplers will be attached are being engineered and manufactured. The original manufacturing company has backed out of the design and production of their proposed  system. They guaranteed their ability to produce a system that would meet the requirements of this project but have recently decided that they would not take the responsibility for the liability for these requirements. Williams has developed the material because of the increased stress incurred in todays drag racing cars.

Williams invested in the equipment that was needed to meet these requirements. They certainly are backing this racers needs.

The new design insures the ability to steer the car at the goal speed.

This is the first application of a Greek coupler in a high speed steering system.  There is zero tolerance for deflection in a system like this. These speeds  have never before been generated in a driven wheel that is also required to steer the vehicle. There is no prior system to modify. This is a first time application that has no room for error when the surface speed is a mile every 6.55 seconds.

The couplers that top fuel and funny cars use today can be manufactured with a crown on the male fitting. It can't bind and is easier to keep it lubricated because the female side can have a seal. It could possibly be run wet like the latest trailer wheel bearings.  It is not a change that can be seen, but since we only have 3 degrees of steering to begin with, it must always work.

Ball bearings will replace the previously supplied taper bearings. Longer life and less rolling resistance has dictated the change. The new hubs that have been designed also have larger ball bearings.

These changes also require redesigning and manufacturing the spindles.

All of this is being handled by Mark Williams. 

The foto is of the original hub.

Freud,

I noticed in your description of the new steering components for the Treit liner that larger dia. wheel bearings of ball bearing design replaced the original smaller bearings. When I think of bearings getting larger in high speed applications I get concerned for exceeding the maximum rpm (surface speed of the bearing) recommended by the manufacture. This is easy to do, but they have some pretty smart people working on this project so I am sure that that was considered. Still spares in the trailer might be a good plan!

BHarmon....your response is greatly appreciated. I'll make certain that this is brought up with the design team and get their comments.

Thanks for your interest in the project.

Freud,

Glad to hear Mark Williams is involved. He is very knowledgable when it comes to drivetrain parts. I aways wondered why more people don't use the Greek coupler for different ways to transmit power. They are almost bulletproof.

Asking questions is one's only way of getting answers. As a young boy I was always taught that there is no such thing as a stupid question. It suggests that the quest for knowledge includes failure, and that just because one person may know less than others they should not be afraid to ask rather than pretend they already know. In many cases multiple people may not know but are too afraid to ask the "stupid question"; the one who asks the question may in fact be doing a service to those around them.

If I get access to any engineering drawings or better yet to the new parts, I'll post them on here.

Desotoman, Marlo is constantly looking for any technology or parts concepts that will improve the design. That relates to systems already installed as well as ones in the future. That's how the Greek coupler came into play. If a new item comes available that will add reliability or safety to the car, the prior system will be replaced with the new product.

I too will be waiting for some more progress.
