Slippers/Slipper Clutches - the start?

[rocketrob]

A little trivia for the day.............


Anyone around anymore old enough to know the advent of the slipper clutch copied and used in literally every electric vehicle today... who invented it, year, vehicle, etc...???????????

[Wraggy]

1st i knew of them was on the RC10 Worlds edition i think , when they started using the Stealth gearbox.. so would be 1990 i think, not sure if the Losi hydradrive was out before then ??
im sure someone will correct me if im wrong

[Northy]

But I think AE might have copied it from the RPM gearbox that was out before the stealth, that looked very similar......

There was the Racing Clutch option for the Optima series in 86-87, and I think the Turbo Optima and the Salute had some kind of slipping device on the tranny, on the layshaft this time.
The Optima Mid (1988) had a slipper on the layshaft too.

I don't know elsewere, but here in France, everybody thought it was a useless device until the Worlds in Australia, back in 1989, where it became evident that you had to use one at least in 2wd, to be able to use crazy winds like 13t .
I may be wrong but I believe they were using the old diff system on the original RC10 tranny (on the spur) to have some kind of slip...

If I remember correctly the original Yokomo 834b dogfighter had a slipper on the sprocket that drove the chain to the front gearbox - that was mid 1984.


Edit: On further research, discovered that it was the RPS Wonder Dogfighter that had the above slipper, which technically was called a torque splitter (that's what they called it on the box), but works just like a slipper.

I honestly now can't think of any car earlier than the Optima Mid....

here is a team pitstop jrx2/pro slipper ready to bolt on my rpm jrx2 when she arrives


and the first 834b 1983 had no slipper,the late 85 wonder dogfighter did and so did the rps-se edition
