Throttle pedal
« on: 03 December, 2009, 09:27:44 AM »
Still gathering parts for building a s2, (will start to build after the new year). Lots of thinking and pre- planning going on in my head. I am a time served blacksmith and am very confident with most parts of the build, my weakness I feel is the electrics.
I am using a mobility scooter and I'm not sure how to get the functions of the thumb flap lever for forwards and reverse into a throttle pedal and a gear lever for forwards and reverse.
How have others achieved this?

Jock

I am already thinking about a mayfair for my daughter after the s2, probably getting ahead of myself. I can see "Tore" has started one using a cordless drill for the motor. Can't wait to see how that goes!

Jock,
As you may read my recent post I'm also just starting a TL2 based on a scooter, I'm an electrical engineer so shouldnt have much trouble sussing this out (famous last words), when I get my scooter- hopefully this w/e.
If the controls are the same, and they should at least be similar then I will endeavor to take some pics and do you a sketch of some kind.

Regards,
Steve Hopkins

Hi,

There's plenty of discussions about using a 'wig-wag' pot with a pedal, have a rummage around in older threads.

Happy hunting (+ building)

There's some in here - http://toylanderownersclub.com/forum/index.php/topic,378.msg2880.html#msg2880

hi jock,
 i spent 5 hours making the wig wham thing into a gear lever last night and even though it took me so long it was easy.
the mistake i made was making it to big to fit inside the transmission tunnel, but if you look on here there is lots of info.i split the white wire and used that for the accelerator pedal , IE :put into gear press button go!!. what i did (doing) with the touch pad from the scooter is to cut it out whole and fit it into a box below the dash, ill post some pics. this way it avoids me have to pull my hair out and keeps all the electrics together as they should be and the loom stays in one piece.
i followed Walters advice and fitted springs to the lever so that it doesn't jump out of gear.

Hi all,
The easiest way to use the wig wag/potentiometer is to use it as a throttle pedel and use a six way rocker switch to swap the direction of the pot. This will allow you to only use one side/throw of the pot. It will of course allow the vehicle to travel the same speed in forward and reverse!
I have done this on my son's Geepster and it works fine.

Hi Neil, could you go into a little more detail on the "six way rocker switch"???
 And how to wire it.

Thanks, Jock

Hi Jock

I'll try to sort the diagram for you cos it's been a while. All you are doing though is swapping the drive over on the pot. It should have three wires coming off it. The middle is the common and the other two are forward and reverse (this is unless you have a forward/reverse switch on the donor scooter). normally you would use say your right thumb for forward and your left for reverse, but with the switch fitted you would be able to just use one side/sweep of the pot for both forward and reverse. I just stripped out all of the other components from a Shoprider tiller head, turned it on it's side and fixed it in position in the footwell. It acts just like a throttle pedal. One of the best and easiest scooters to use is the Shoprider 888/Sovereign. The electronics are simple to use and if you get a older version it will have the switch fitted under the tiller.

Good luck
Neil

Jock,
Have a look in the Toylander manual for the 6 pin rocker switch - it's on page 49 of the T2 manual. It's a 3 position switch - forward, off, reverse.

Neil,
Do you know if you can use the linear pot supplied by Toylander and a 6 pin switch in place of the wig wag? ie is the resistance about the same? 5,000 ohms.
Regards
Mike

Hi Guys
What you need to realise is that the WigWag is a pot with centre position as off, moving one way produces forward and the other way produces reverse. If you power up the buggy with the wigwag off centre, it will go to failsafe mode and the controller will shut down. Half the pot is forward, half the pot is reverse!
If you use another type of pot, even with the same resistance, it will need to be at its centre point for "off" position, so only half the travel is available for forward, Lifting the pedal would give reverse.
For this reason I have mounted the wigwag in the dash area, and it is pulled down by the throttle pedal. As the link is a bit of thin chain, it can't be pushed up!
Regards
Walter

If you need more details, or a diagram about reversing, let me know.
I have posted it previously, but I can't find where! So I'll sort it and post again if you want, or send me a personal message and I'll email it.

Another quick note, some controllers (such as the one I used) go into fault mode if the wigwag pot wiring is broken ie, trying to flip the resistance with a switch to reverse it.

Hi
Tufty's comment is another stumbling block. You have to reverse the wiring with the controller TURNED OFF.
So here we go...............
When in it's "normal" state, the wigwag will give forward motion for a particular movement of the pot.
In it's "reversed" state, the same movement of the pot will give reverse motion.
But the sequence has to be
Switch ignition on              for normal drive.
Switch ignition off.......operate reverse switch.......switch ignition on       for reverse drive.

The picture shows the pot and it's THREE wires.
Normally
wire A goes to Tag 1
wire B goes to Tag 2
wire C goes to Tag 3


To reverse the controls, a switch or relay is required so that it changes over so that
wire A goes to Tag 2
wire B goes to Tag 1
wire C goes to Tag 3 (and must not be altered)



You can see from this pic that wire A will go to lead 1 with the switch in one position, and to lead 2 in the other position. Similarly for lead B.

I hope that this makes sense so far.

How you actually achieve this is up to you.
You can use a switch, and simply turn the ignition off, then operate switch, then turn back on.
Alternately you can use an additional microswitch under the throttle, wired in series with the ignition switch so that releasing the throttle pedal turns off the controller, (but not the other functions such as lights).
I used a relay to do the reversing, and operated the relay from switches on a "gear lever".
These switches are arranged so that as the lever is pushed forward it puts the controller power on.
When the lever is put back in neutral, power is turned off.
As the lever is moved into reverse, it operates a switch, which operates the relay, before a second switch which then powers up the controller.

Take it one step at a time and you should get it sorted OK.
Best Wishes
Walter
