Re: pic: what do you think?

i think that this might be problematic when it comes to meshing the gears....this is the reason that most teams use shifting "dogs"

it still looks like a sold design but will only be effective if you stop to shift

Not at all. It actually works better when it is moving. We played the whole season on our transmission which follows the same principles. Just get the gears hardened and leave a little gap between the gears being meshed and unmeshed. I don't recall how much ours is, but I can find out if you want.

Very nice transmission, it looks a lot like the one we build, did you ever see it? The nice thing is that it is much lighter than using a shifting dog, and requires much less resources. Instead of one piston, it uses two, so there is not multi positioning of pneumatics. Maybe you could use a servo instead for the multi positioning/shifting. The whitepaper on ours will be here some time soon, check it out when it gets posted.

Jim told me that it was 0.015" + center distance between the gears. Shifting works like a charm with this beauty.

It was a pleasure to be next to the Killer Bees all weekend. Many people came by to see the 4-speed shifter. Heck, even I was demonstrating it to people by Saturday!

Re: pic: what do you think?

Are there any pictures/specifications about the killker bees transmission. Also, I was wondering if someone would explain how the "dog" shifters work in a transmission. I've been looking at specs..such as 45's newest gearbox, but have had no luck figuring it out myself.

Sorry if this is a little off topic

That's the thread about it, and in it, Raul posted a picture of it that can be found here: http://www.chiefdelphi.com/forums/at...achmentid=1962
