Post Traffic Clutch
Were there some details/pics on Traffic Clutches on this forum?
Did a search but didn't find any real info.

Cheers

Post Re: Traffic Clutch
I had a trafic clutch in one of my cars (ami 6 '64) it had no clutchpedal either, it had a vacuumbox connected to the clutchlever operated by a button at the gearchange lever. The car once belonged to a french ww2. soldier lost 1 leg in the battle.......... You could drive of only hitting the throttle and when you shift you have to push the button and when you relaese the throttle the inletmanifold vacuum released the clutch and you could shift. It still lays somewhere in my garage, no foto's at the moment..........

Worked great.........

So I know what I am going to do when I loose a leg :lol: :lol: :lol: :lol: :lol:

Sounds a bit like the pre-select that buses use a few years ago :-)

No it's not pre-select. There are two clutch (plural of clutches is clutch?), normal foot activated one and the Trafficlutch. Trafficlutch is a centrifugal clutch, the clutch shoes fly outwards as the engine speed increases and engage with the flywheel. Moped like 'twist and go'. First and reverse are selected, at tickover, without touching the clutch pedal - peddle - peadle - peddel - round buttony thing on the floor, dammit. Wine is the curse of the thinking classes... Anybut, shove it in gear and then boot it, centrifugal clutch engages as the revs rise and off you go. Stop at junctions and such without touching clutch in whatever gear you are in and then stuff it back in first or second - second is good in traffic on the flat as you rarely need more than second in a traffic confiture and it will pull away (at least lightly loaded) in second quite happily. The carb has a damper to stop the revs dropping too quick when you lift off as it disengages if the revs drop to tick over, not good for engine braking if you fluff it... Changes up and down the box are made with the clutch peddle (buttony thing) as normal. I don't like Gerty's, as Russ says, it judders, part of the prob is the drive shafts being simple UJs and naturally lumpy on lock but haven't investigated the skewed flywheel yet. Other Trafficlutch may be fine. Later Citroens; GSA fer e.g. had a thing called a 'C matic' which was a 3 speed floor change without a clutch peddle, you just changed gear with the stick while your foot bounced up and down pretending there was a clutch... I worked for a Citroen garage in the late 70s and drove lotsa different stuff...

But, can't we keep the one wot uses a 'pedal'?

'Peddles' belong on a cycling forum (or ones for illegal drugs, if such things exist). ;)
