hg70 Posted March 30, 2012 Report Share Posted March 30, 2012 i have a crappy gear selector that i want to changei know what i wanti know how it should worki know it will be safei don't know how to build the electronic as you can see in the pic it's a simple design to keep it reliableit uses the 12v acc power to power the unit but i'm thinking it might be better to use the 12 batt power to run the solenoids via internal or external relays, i'd prefer internalthe safety must be pressed or pulling the stock/modified shifter will do bugger alli was thinking of two industrial momentary switches telling the what ever to fire off the solenoid, i also want the what ever to have a delay of 1-2 seconds before it can fire off the next solenoid so the box it not going to miss a gear and blow up, it's a light truck gear box but still it's $1500aud to repairthe what ever needs to fire to two solenoids in a specific order to go up and the same order in reverse to go back downit's like a tip tronic/paddle shift system without the pagani zonda hanging off itso i assume you are all still with me do you have any ideas how to make the what everand help would be awesome Quote Link to comment Share on other sites More sharing options...
hg70 Posted March 30, 2012 Author Report Share Posted March 30, 2012 found a problemi'll need to add a third solenoid but shorter solenoid above S2 (easy as) so it go to a neutral position so the firing order will have to beFIRSTS1outS2inSECONDS1inS2inTHIRDS1outS2nilS3inFOURTHS1inS2nilS3inFIFTHS1outS2outREVERSES1inS2out Quote Link to comment Share on other sites More sharing options...
Hero999 Posted March 31, 2012 Report Share Posted March 31, 2012 Your drawing says, you need 5kg to 10kg of force over a 50mm to 70mm length but you didn't say how fast it has to move? It's quite a lot of force for a solenoid. Another solution could be pneumatics.The simplest control solution would be a PLC (Programmable, Logic, Controller), which is basically a pre-built control module which can be user programmed.

hg70 Posted April 1, 2012 Author Report Share Posted April 1, 2012 cheers hero i had a look for plc's on ebay, are they easy to program or would a normal ic be better? i have never programed anything before.i contacted a few company's for a quote to build the unit and it's around $5100 aud, the solenoid speed will be fast but i should be able to adjust the speed via voltage but no one seems to stock the large units i need. i have been looking into pneumatic rams and it would give better control plus they are dirt cheap.
