Here is my third and i think my best upload today: a working "carclutchsystem".
As you probably know, a clutch disconnects the engine from the gearbox and wheels, so when you're braking, the engine doesn't stop.
Mine is the same: by pushing the pedal (it's the piece I'm pushing with my finger on one of the pictures), the grey piece slides backwards taking with him the transmission axle so that he disconnects. An elastic puts everything back in order when you're no longer holding the pedal.
A real clutch works with plates; I'm using several and different transmission pieces, choose the one you think is the best. (pictures of them are a bit lower on the page)
One problem I found: would you be a lego car driver, you wouldn't be able to park your car because you couldn't play with the clutch (I'm thinking of the saab james may was testing in "the worst car in the history of the world"); it is nothing or everything, tere is no progressing torque being deliverated to the wheels (I'm working on one of these plateclutch like every car's got)
THIS IS WORKING, I tested it and I'm putting it right now on a large scale car (it's an porsche 901 or 930 turbo with also brakes and an homemade gearbox and boxer flat 6)
Pictures of it fitted in a car will come in a near future.
Thanks for watching, and if you understand it (my english is a bit strange) leave a comment or rate it, and I will be glad if you participate on this projects: any ideas, any question, any critic: leave a comment, I will be glad to read them ;-)
ps: have a look at my other technic engineering creations (brakes and boxer engine had been added today) and also all my large scale cars
Good job using just legos. I give in to temptation and used "other parts." If you're more concerned with functionality rather than being pure, I found that springs in ball point pens work wonders with legos. As for discs, I'm working on the same thing. I figured out the pressure plate thing but just like it was pointed out it's "all or nothing."

Another nice one, but...(again) clutches work with a disc and rubber to prevent gears (from the gearbox) from slipping. Anyway, it's really nice to see a so small clutch. 4/5
Thanks for the comment: I am working on a plate clutch but the problem with them is that you will need an enormous force to create the connection between the lego plates (if there will be one). But I will try it with 2 plates and soft lego pieces. ;-)
