Does anyone know when automakers/racers first used rack and pinion? i know they were around in the late 60's but i was curious when and if they were used before that. thanks
There are probably earlyer, and better, examples but I know Triumph Herald (English) had it in 59/60. The earliest American production I can remember would be Pinto.
There were a lot of different English cars around here back in the 50's and we've found a few mouldering hulks left in the woods that had R & P steering. Can't tell you what they were, except they were unitized construction and had round bottom chassis members up front. That might ring a bell with some of our British friends...???
don't know the year,but this is the guy that invented it. http://en.wikipedia.org/wiki/Rack_and_pinion
citroen could not have used it in the 1930's ,it was not invented till way after wwii..as noted in my links above.
He invented variable ratio rack and pinion, not rack and pinion steering. I have seen steam engines with rack and pinion steering from 1890.
His 37 Citroen Traction Has it .That's how I know .Also is frontwheel drive and unibody ,Or unitized .Im still curious who was the first to use .Rack and pinion.
I vaguely remember seeing a picture of a steam powered "Traction Engine" (tractor) from the 19th century and thinking, "That's got rack & pinion steering!"
Citroën 7CV (Traction Avant) had rack and pinion from June, 1936. And the entire line has been front wheel drive since 1934. As well as four-wheel independent suspension on all cars sine 1934. Firsts on all points, as far as mass-produced autos are concerned. For that matter, Citroën is currently the only manufacturer to have ever used hydraulic steering, ie: with no primary mechanical link to the steering wheel (there was a backup link, with about 1/2 turn free play).

rack and pinion concepts have probably been around longer then Jesus , just need to be applied to thingd like steering.
