2CV's suspension cylinder.
These cylinders were located longitudinally on both sides of the car .
As well as the rolling movements, the rocking aft-and-fore motion of a car passing a bump is undesirable. To eliminate this motion, W. Kootz and K.I. Crossley had independently the same idea to couple the front and the rear springing so that the chassis remains level when meeting the bump. Although Kootz and Crossley had the idea first, it was J.J. Charley that achieved the design first and so can he be attributed the idea that made the Citroen 2CV so popular starting in 1949.
This system has the same effect
longitudinally that the anti-rolling bar has laterally : when the front wheels
rise because of a bump, the spring located under the chassis is tensioned and
tend to make the rear wheels rise as well.
To perform the coupling, Citroen used a suspension cylinder that acts like a
spring
