Electro pneumatic paddle shift system
Currently started designing electro pneumatic gear shift system for formula student racing car. Been told that CVT sytem may be able to help me in some way with the implementation of this system. any ideas or ideas in general! Have designed initial circuit but need a way of cotrolling it. Need some sort on controller with timers that work in increments of 0.01secs, using it to control valves and cut ignition on initial depression of paddle. Any info., help or comments welcome!

Depending on your ECU, you should be able to use a spare input channel wired to the paddle switch for the ignition cut. F1 teams use MOOG brand valves for their gearbox controllers, so you could start with them.

Make the system to suit normal sequential race gearboxes not just bike engines. There are currently not many systems available for proper racing gearboxes that work. Have a look at the Zytek system on there website expensive but could give you some ideas and it is solenoid operated only so no drain on the engine from running the compressor.

Take a look at:
http://www.bikeshifter.com/ Just one of many quickshifters available; of course, you may want to 'reinvent the wheel'! |

I don't remember where I saw this really clever method of cutting the revs. The throttle cable is held in a 'kinked' position by a solenoid. when energised the solenoid relaxes its pressure, momentarily lengthening the cable and cutting the revs.

Translogic bike shifters are one thing I've looked at. Quite expensive but they appear to have a fair number of successful customers, Suzuki British Superbike team to name but one.
Which Uni are you developing for if you don't mind me asking? |
