2wd buggy CAD development
Hey all. I have decided to embark on the journey of designing a 2wd buggy. Most likely, I will be sharing the actual dimensions and plans with Caster, but for now, I can post my progress here. Here is the original post for the Caster forums:
I have just started to download/install Autodesk's inventor CAD program onto my personal computer. Unfortunately, I dont have the money for the actual program, just the 30 day trial. So, that is my time restraint for this project. Anyway: I am setting out to design a 2WD buggy. Since this will be the most in depth project like this I have done, there will be some flaws. If any of you have some design ideas you would like to share, please do so. I dont want to forget any elements. |
Unfortunately, I have already hit a road block. I do not actually own a 2wd buggy (closest thing is my t4). So, I have no dimensions to start out with for this buggy. I would like to start with the overall shape of the b4 arms, and bulkheads. Can anybody post some dimensions of them for me? :D
|
If you are just going to go off an existing buggies dimensions, you aren't exactly designing anything new. Get ROAR's rule sheet, and design a buggy to meet their standards.

what software are you using? My day job is behind a computer crunching away on solidworks 8-12 hours a day. I have a 8th buggy project in the works for the last year or so, however it's hard to find time or motivation to work on it lately. Kinda like how a mechanic never works on his own cars lol..

I have been using Inventor 2012, now the 2013 version. I don't know anything else, as that is what I've been using since middle school, up to where I am now.

Wait until you discover Solidworks. Honestly if you've used Inventor that long you know the ins and outs and are used to it but IMO it is WAY too difficult to use. Solidworks is very intuitive and powerful. I assume you're 3D modeling this? :)
|
Inventor Fusion is for editing solid models created/imported from other programs. Doesn't sound like you will need it if you are only using Inventor.
|
Ahh, that makes sense. I will be back soon after I create a rough 3d form of the bulkhead (front). I want it similar to the t4, but with my tweaks thrown in.
|
All right, I've made the bulkhead. But before I finalize it to work with the chassis, I thought I would ask this. For a potential buggy, would you guys rather see a more traditional design-B4-, more innovative design-22, DEX210-, or off the wall designs? I am thinking of doing a mid motor setup.
Just so you guys know, I do not work for Caster. I am just trying to help by having a rough design ready for when we finish our current agenda. Plus, school ends in three days and it is a great time for me to do this before big race season starts. |
to suggest something for the buggy design, i really am not a huge fan of the newer buggies (dex210/tlr22) having the aluminum main plate i like the traditional composite chassis and i think (i know this is harder then just saying it) you should just add a little of everything, like all the things you liked best in all the buggies or all the most innovative or best design of them all :nod: also you should make the buggy have a longer chassis but not as long as the 22 but longer then the +8mm b4.1 maybe like -8mm on the 22 chassis :lol: so it can still be stable yet agile and quick and has lots of traction :)
hope this helped in some way :lol::lol: |

Two directions you can go...
I used to do a lot of concept design work and have some proto drawings of onroad/oval pan cars as well as 1/8 nitro late models.
You can go two direcitons... 1. Take a already great design and further improve upon it... My thoughts there would be a b4 based design with slightly narrower chassis, droop screw adjustment, adjustable chassis length but still composite. 2. Start from a clean sheet design and come up with something totally new.. This is a hard road but usually still starts with a base idea... I would start with a list of all the things you really like and dislike about past buggies you have ran or looked at and then go from there Good Luck! |
One thing you might want to do is to design this thing with as much compatibility with current aftermarket "widgets" as much as possible. That way there will already be some spares at the hobby shops if this ever comes to fruition.
Design it to use common wheels, bearing sizes, screw sizes and camber link lengths as much as possible. In fact you might want to try to design it so you don't need a vast array of screw lengths either. That can save racers money because the designs currently out there will have an advantage as far as distribution goes so if your design can actually cut down on the amount of spare parts it actually needs that could help. |
