USF1 -- F1's All-American Challenger

[cooper-climax]

9.6.2 No forward gear ratio pair may be :
- less than 12mm wide when measured across the gear tooth at the root diameter or any point 1mm
above or below the root diameter. Above this area each side of the gear teeth may be chamfered by
a maximum of 10 ̊. In addition, a chamfer or radius not exceeding 2.0mm may be applied to the
sides and the tip of the teeth ;
- less than 85mm between centres ;
- less than 600g in weight (excluding any integral shaft or collar). If an integral shaft or collar is to be
excluded the mass of this may be shown by calculation assuming the gear to be 12mm wide and
the shaft geometry to be the same as that where slide on gears are used.

If they are close to these minimums, the gear cluster should be pretty much square? a transverse G/B might even be a little longer because you still need room for the diff?

sorry if im misunderstood, but does 'transversal' mean that it is actually in 90 degree position from what they use now?
I dont quite understand this, although i do. This shows how Americans are, they go their own way on theings and dont follow the rest.
The reason it is placed like that probably has to do something with the wheelbase, if im correct the cars have a maximum length and by building the gearbox like that they can create a longer wheelbase. The diffuser doesnt have to have problems wiith that, the tunnels can end before the gearbox, guiding the air over it.
However it will be, i am really interrested in their car, probably gonna be a radical different car, it is a gamble, wich can be won or loss, hope for them it will be won.

In a transversal gearbox the axis of the gearbox would indeed be orientated in a 90° angle to the main axis of the car.

It actually makes for a shorter car compared to a longitudinal gear box.

The gearbox is normally conical and the thicker end points towards the engine. If the box sits transversal it obviously will collide with spaces which are now used to guide air. Logic says the impact will be on DDDs and the free space between the DDD and the wing. The aero cross section will become smaller in one or both these areas.

The transverse box has the main shaft perpendicular to the crank.
ricardo:


seems compact enough,

[marcush.]

the transverse gearbox layout needs on the input shaft some means of a bevel /spiral bevel gear to rive the transversal gears.with the low crankshaft height you will either need to find space for this arrangement in front of the gears or beneath ,the first will surely eat up all advantages of the transverse layout ,the solution to go below the gearcluster will raise the mass in the box....
I ´m not dead sure ,but something like this was used on the 95 Ferraris of Barnard with the fabricated titanium gearcases .With technology going forward and gear width in the region of 9mm the
trnasverse layout may still be able to shorten the box considerably,but i could not find any dimensions of these parts,but gearbox face to diff centreline looks like around 300mm I´d say.

First attempt at a USF1 livery. Tried to keep it simple. Didn't really want stars and stripes all over it. Based it on the All american racers/Gurney F1 cars. Eagle decal at front reminds me of the Jordan cars from the early 90's when it had the snake head following to the rest of the car.

[PlatinumZealot]

I like that.

Though I have a feeling it might be designed in the colour scheme like the Team USA Olympics jerseys.

Wow - fantastic job.

Is Bestbuy officially on board as a sponsor, or is it just fictional?

Great, regardless. =D>

But, suppose this arrangement includes the ability to mechanically adjust ride height during pit stops? The ride height under full fuel load will be the minimum, but after burning off a substantial amount of fuel, the ride height will increase substantially and influence underbody aero effiency.

Commentary on the coil-sprung arrangement everyone seems to think they'll employ.

This could be huge...the car can't have a device that adjust ride height, and ride height cannot be adjusted while the car is moving...but during pit stops, an external adjustment is completely acceptable.

I would expect a fitting somewhere on the front/rear/both of the car that would allow a specially designed driver to socket on, rotate a preset (on the driver) number of turns, and disengage - all within the sub-3 second pit stop.

The ability to keep a somewhat consistent ride height over the course of the race could add up to quite significant performance improvement over the competition.

[countersteer]

FOZ, That one cracked me up... It would be just like the stock car boys "puttin' a round of wedge" in the car...

[Fil]

This is what you want to see in Formula 1 tho.
Whilst not technically innovative in its purest sense, it is a modern-day/tech innovation and brings real differentiation between the cars.

Whether the gearbox layout (or even the discussed coil-spring front susp) ends up being successful or not, they certainly should be applauded for having the walnuts to give something different/unique a shot.

More of it i say!!

[FW17]

IRL Cars have a hydraulic system for the front suspension that can be controlled by the driver at all times with something like this . However this system is not allowed in F1. There was a thread here that Renault is also planning some adjustment to the height during the pit stop but somehow I don't see a adjustment to the right height by a mechanic possible in a 3 sec pit stop.

Can the ride heights be adjusted by the driver during the pit stop?

Not entirely updated on this marcush, but I think it also has something with the geometry of the bevel/spiral gears?

The transverse 'box has those at an ideal 1:1 symmetric arrangement, while the longitudinal such needs to have a reduction as well as an offset there, which makes for more sliding contact and as a consequence; higher power-loss. Scarbs?

Dude! The whole team is fictional until a car is proven to exist.
