Semiindependent Design Using Superimposed Suspension Elements

Inventor Gil Scigalski of Illinois sent us the following description of his concept for a semi-independent suspension 'In its general layout the design resembles a Ford twin I-beam suspension, but with the characteristic long overlapping swing axles pivoting from unsprung rather than sprung parts of the vehicle. The unsprung parts consist of vertically aligned, chassis-mounted struts similar to the sliding pillars used on Morgan sports cars. In addition to transversely locating its associated...

A suspension revolution

Wheel camber control is always imperfect and involves compromises and limitations, right Not according to one inventor n this technological age, genuinely new ideas are as common as hens' teeth.

In that spirit of constructive scepticism then, let's take a closer look at the 'VXI' suspension system of...

Design Criteria

A number of design criteria were given to Hembrey's team by the Formula On* Teams Association and the FIA, but the Pirelli engineers also had input into the specification.

'The first thing we were trying to fix was the...

The Aircraft Analogy

Lift or CL vs angle of attack is shown in figure 2. As we can see, things are pretty linear as we ge near the stall. This is also going to affect the elevator f horizontal stabilfsei but, as we commented before, the aspect ratio is significantly lower for The elevator horizontal stabiliser, so the stall angle Is much greater. What this means is the horizontal moment or control power of the elevator will drop off, but not significantly. As the aircraft approaches the stall, if the aeroplane is...

The Cdswdrth Xd

Perhaps inevitably, the decision became a blend of objective analysis and subjective opinion, coupled with the aforementioned desire not to follow the crowd. Menzies 'Some of the big V8s seem to have almost unusable levels of torque, whereas the Cosworth XD seemed to be more like a big motorbike engine, with lower torque and lots of revs,' to which he might have added, 'like I had become used to with the supercharged Hayabusa'. And sequential gearboxes with flat-shift...

The Inventor S Claims

Having read this introductory assertion, probably the first question to come to mind is what is there left that could be designed into a suspension linkage system that warrants a patent Well, who to put it better than the inventor himself 'The list ot features and benefits includes the following 1. Absolutely zero track width change (zero wheel scrub) during suspension deflection. 2. The ability to set absolutely zero camber change, or to have the camber vary according to pre-set parameters....

Tom Walkinshaw

Mo or racing lost one of its great characters just before Christmas with lliededlli of Tom Walkinshaw, a man who was as adventurous at the helm of a company or race team as he was at the wheel of a racecar.

Tyreless Lsr Wheels

According to John Ackroyd, designer ol the Thrust 2 jet land speed car, a tyre-less wheel on dirt has about a .30 friction coefficient. As a comparison, a tyre on salt has about a .50 friction coefficient. My guess is Ackroyd arrived at the .30 friction coefficient by calculating fiom the late of deceleration when the brakes were applied on Thrust 2. I don't know what the friction coefficient is for a tyre-less wheel on salt or a tyre nn dirt. However, obtaining answers to these questions might...

Waterman Electric Pump

Waterman Racing Components Inc has developed a new, NASCAR-specific electric fuel pump. Designed with the proposed GFI systems in mind, the pump's main benefit is it utilises a brushless notor, so draws just over six Amps during use - considerably less than comparable units. It also has a digital controller with a six-mode emergency shut off. which will be required by NASCAR for all electric pumps once they are introduced. The pump will also operate with the existing carburettor set ups,...

Xtrac Perspective

Designed its 1044 gearbox for use in all the Cosworth-powered F1 cars, but achieved the most success with the development programme run with HRT kk Following the FIA tender process in 2009, it was clear there could be as many as four new teams using the Cosworth engine in 2010. It was felt that this presented a great opportunity to share design, development and tooling costs, and to save valuable time, if Xtrac put together a gearbox package that the new teams were all able to use. And so the...
