  Batmobile Forever Question
 From: starlight | Posted: 9/3/2004 2:35:24 AM |

Batmobile Forever Question
How does the batman symbol stay stationary on all 4 hubcaps while the vehicle is in motion?
Was it movie magic or is that possible with simple mechanics?

Can someone explain how that works?
I searched on the net trying to figure out how such things could work but with no luck.

I appreciate any help as this has been one of my long unanswered questions.

RE: Batmobile Forever Question
it is possiable, but im not really sure how they did it in the movie

RE: Batmobile Forever Question
Although I don't know first hand if the is what the Kilmer car used, this effect is achieved by using a spinner wheel with a counter weight on the bottom. Here is a nice one.

RE: Batmobile Forever Question
Here is one that also utilizes magnets

US Patent #06135569

If that link doesn't work just go to http://www.uspto.gov/patft/ and search the patent number. Also look at the patents that this patent references.

RE: Batmobile Forever Question
Not sure if above linked products would be it?
I've seen similar things in real life and those things are not necessarily stationary.
Even at lower speed, the hubcab would still wobble(?) a little.

In the movie, the logo is seen perfect stationary position (Even when Christ O'Donnel character takes it out for spin and bumps the car up and down).
I thought maybe it was super imposed with special effects later but I saw many shots in the movie (different angled shots that show very little of the hubcats but nonetheless show that the hubcap was still stionary) that suggest otherwise.

RE: Batmobile Forever Question
I think the style with magnets by the Chrystler Corp. would stay very steady. I'm sure they're not using refridgerator magnets... :)

RE: Batmobile Forever Question
Then what I don't understand is how come these types of wheels aren't installed in normal vehicles?

Woudln't it make sense for any advertisers to have their cars with their company logos fixed in stationary position? Or you can even put company website address on those

RE: Batmobile Forever Question
spinners is what i thought of at first but i dont think thats what they used, it takes up a lot more of the tire then just the rims, and while the same pricaple of spiners could work i just dont think thats hwo they did it.

RE: Batmobile Forever Question
after looking at it some more, i do think they used spinners, least its the only logical soution i can think of. seeing as the the outter shell covers up most of the tires http://www.aloofhosting.com/gothamgarage/assets/images/db_images/db_foreverbatmobile37.jpg they could have had enough weight on it.

on a side note i actully like the forever tire rim deisgn more then the 89, will i do it on my 89, no. putting the logo on a replica, big no no, lol.


 From: sg1star | Posted: 9/3/2004 9:39:28 PM |

RE: Batmobile Forever Question
quick add on, im sure they used spinners now http://www.aloofhosting.com/gothamgarage/assets/images/db_images/db_foreverbatmobile421.jpg

the back tire is not level.


 From: starlight | Posted: 9/4/2004 2:35:13 AM |

RE: Batmobile Forever Question
Can you explain how spinners work?
I guess it rotates in opposite direction of the wheel but what and how does it control the rate of spinning to match the rate of wheel spinning such that it maintains the stationary look?

Thanks for all the info.

RE: Batmobile Forever Question
Spinners just spin freely on bearings, like a roullette wheel.


 From: BatDemon | Posted: 9/7/2004 5:54:34 PM |

RE: Batmobile Forever Question
they're not spinners. spinners stay spinning after the vehicle has stopped. the forever wheels have a stationary hub, meaning the centers don't move even though the tires do. one of the making of articles mentioned bearings cominf off the wheel hub.

RE: Batmobile Forever Question
u could be right but i dont see how that is possaible seeing how the axel has to spin for the tire to move, spinners with counter weight would be the logical way.


 From: sg1star | Posted: 9/7/2004 7:05:39 PM |

RE: Batmobile Forever Question
u know what forget what i just siad, i was thinking of something totaly diffrent, ur right they could have been stationary hubcaps.


 From: www.1989batmobile.com | Posted: 9/7/2004 9:30:25 PM |

RE: Batmobile Forever Question
You're not understanding.

Yes, they are spinners. Spinners with a counterweight at the bottom to keep it stationary while the wheel "spins". They may also incorporate a strong magnet located behind the wheel to help keep it from swinging as the counterweight alone may not be enough to keep it in position. Normal spinners do not have the counter weight or magnet so they tend to spin with the wheel and continue to spin after the wheel has stopped.

That said, it still hasn't been confirmed that this was the technology used on the Kilmer car, however there arn't too many more ways to engineer this. It could have had a gearbox that counter spun the cap against the wheel but this would most definately be hard to keep aligned for any period of time. And even then it is still a spinner.

I wouldn't be suprised at all if it turned out that there was simply a small wire or two that attached the spinner to the fender, holding it in place while the wheels rotated.

RE: Batmobile Forever Question
stationary hubcaps and spinners are kinda simulaer. stationary hubcaps have been being used in advertisement latly, heres a link http://www.vanman.co.uk/hub/
but although they are simulaeer they are diffrence hence why they have diffrent names


 From: starlight | Posted: 9/7/2004 10:24:46 PM |

RE: Batmobile Forever Question
All those stationary hubcabs i've seen commercially still wobble.
The batmobile from forever movie were in fixed position regarldess. Even during that scene when Robin takes it out for a ride and bumps the car up and down.

RE: Batmobile Forever Question
The new Rolls-Royce Phantom has stationary emblems on center of rim. Maybe you could find out from that how it works.


 From: Webmaster | Posted: 9/7/2004 10:43:59 PM |

RE: Batmobile Forever Question
Here's a blurry but screenshot from the continuous long shot where the batmobie makes a left turn.
You can still make out that the emblem is still in stationary position.







Also a close up a car turning shows pretty stable emblem.

RE: Batmobile Forever Question
adding enough counter weight to either the stationary hubcaps or spinners could make them less wobbly, so at this point i still think it could be either method or a combenation of the two, i think the only real way we will know for sure is for someone to go up to the car and pop off the hubcap. lol or find someon that has seen it without the hubcap.

RE: Batmobile Forever Question
i sent a e-mail to some people who wokred on the car so if i get a reply i will be sure to let yall know

RE: Batmobile Forever Question
I have a totally off the wall input on the mechanics of the wheels. I don't have any real pics to share so bear with me. Imagine this as the wheel: =[|] Make sense? I didn't think so. Let me explain as all super villains do with there super intelligent and badly thought out plans. It appears that there is a wheel cover that hides the whole tyre and not just the rim. Perhaps there is a semi-circular wheel well that rests on the inside of the fender, represented above by "[". But it does not touch the axle or the wheel, only shields it on the inside. The axle protrudes near the centre of this half doughnut doohickymabob, and that is where the ordinary wheel is hidden that no one sees, "|". One the outside is the outer wheel cover thing, "]", which is a complete circle that bolts to the "[" part of the cover and also houses the stationary bat emblem. So in a nutshell, you have a tyre hamburger type deal going on with extra bat under the bun.

So there you have it. It's complicated I know, but hey, this is the Batmobile, it's not made for simpletons.

RE: Batmobile Forever Question
How the wheel turn left and right in that case?
