Clutch Actuators

It's been a while since I've been here, but it seems little has changed - Rob's still battering Novas! I've been to the doctor this week, and it seems I've got tendonitis in my clutch leg. To any normal person, that would mean not driving or buying an automatic. Well, I'm not doing either 'cos you can't go autotesting on fott or in an automatic! I need to rest my leg, so I need to activate the clutch another way. I'm thinking a lever on the gearstick, and something to pull on the clutch cable mounted under the bonnet.

I'm sure I could write a little bit of code for a PIC to do the clever stuff in the middle, but what would I use to pull the clutch? The only thing I can think of that will work in the right way is the servo from a radio controlled car, but it'd be far too weedy. Any ideas?

Cheers, Andy

What about a hydraulic release bearing and something with a switch operated pump, or would that be too slow?

Bottle of C02 or N20 with solenoid, and a "air shifter ram" as used on bikes. Been there done that...

But not with the PIC???

Tell me, can you make me a circuit that will control a balancing robot with a solid state gyro and a couple of wheel position sensors???

I did think of an airshifter. I've seen them work both ways for drag racing, but I was thinking for for the capacity of tank, and if he needs it more for everyday driving. Wouldn't an air shifter need a sequential box in car?

Nah, use a couple of rams. Many years ago you used to be able to buy a kit for H-pattern shifts.

Lol - did you ever get anywhere with the climnbing / standing powerchair?

Doubt you'd get enough purchase unless the lever was long. I'd have thought the easy way would be a vacuum servo. But check it out with 'disabled' car makers - they certainly used to make manuals without clutches.

Rip one out of a segway.

No, I was talking about the ram working the clutch???

No but thats because my electronics and programming are crap! Need help!

Reply to

Thought of that but its a price / availability / reprogram to suit thing...

Are they able to apply varying amounts of "pedal pressure"? If so, they sound ideal. Wouldn't want an on/off switch for a clutch though!

It's a company car anyway, so clutches/gearboxes not an issue ;-)

Still wouldn't help with pulling away.

You could still use your foot when you need it to be touchy-feely, like setting off from a standstill. Or could you? I suppose it could be fettled to work that way? Never done one though.

To change gear you want fast depression/release. Thats on off... To set off you want yourself, or a torque converter!

Yes, seen it before but his electronics skills are better than mine!
