Battery Buggy Wheel Stopping Mechanism

How are you all going to stop the motor?

Well, pretty much everything is explained to some degree on the wiki. I would really recommend reading through the wiki, and also some past threads to help you understand battery buggy better. But in short, a wingnut travels down a threaded rod axle as the buggy moves forward. Eventually, the wingnut, which is riding on a sort of stopping rod, will contact the microswitch and thus cut the circuit. It will also lock into place against the stopping point. Thats how bb brakes work.

back when i did it, you typically used a microswitch connected to the motor. How you get the microswitch to open is up to you
Ok this is epic 8-)

For me, my wing nut doesn't ride the stopping rod - it just pushes against it and makes this horrible noise until one of them gives out. How am I supposed to get the wing nut to "ride" the stopping rod?

You can angle the micro switch so it is more parallel with the axle. This allows the motor to be turned off and then coast for a bit before the wingnut engages the end of its track and brakes.

Or I have found a lightweight toggle switch to work well (not sure if dynamic braking is possible though, probably depends on the switch connections).

Need Help Please! My buggy is stopping alright. The Wingnut engages the microswitch and then hits the nut and the vehicle stops. My problem is that the wingnut winds up so hard against the nut at the end that it is becoming literally impossible to extricate it by turning it backwards. Any suggestions what I can possible put in front of the nut at the end so that the wingnut doesn't completely jam into it and sticks like glue. I have tried coiling a wire in front of it but it doesn't help. Anyone have a similar problem? Please let me know. The invitational is this Saturday. I am having trouble just doing the practice runs because after each run I end up having to literally take apart the axle and extricate the wingnut from the stopping nut. Thanks!!

A simple fix if you are short on time is to use less batteries to reduce your speed. However, that is dependent on your motor and the amount of batteries you are currently using. You could also try putting a washer in between the nut and wingnut if the battery idea doesn't work.

I had the same problem last year, and I found that a spring was very helpful.

Thank you! Do you remember where you bought the spring? Thanks again!

You might want to try using a Teflon washer. In the past, some of the kit makers included a soft thick cloth washer, something like felt.

That's a good idea. Let me check at Home Depot.
Thanks!

I took it off a random switch I had at home. Dunno where you might be able to get the same one, but I'll post it if I find a similar one later.

I'm trying to make the vehicle as thin as possible, but it's so thin that a fully re-winded wingnut would only allow it to travel about 5 meters. Would you recommend using larger wheels, enlarging the frame width, or something else?
