This front suspension was presented by Cottin-Deguttes in 1927. No other examples of this kind were developed. to the problem of efficient lubrication of the sliding tubes by integrating in a sealed element guide spring and hydraulic shock absorber. The elastic element is now a coil spring this is probably the first application in which the car weight is entirely sustained by a spring of this kind. An interesting variation of this suspension family was presented by Cottin-Degouttes on a car shown in Fig. and introduced in 1927 the vertical tubes suspension was modified but we do not know the reason for this decision. The tubes are slightly inclined with the top closer to the center of the car while the elastic element is again a cross leaf spring as in the Stephens. The leaf spring is articulated to the sliding strut because the path of the tip of the spring is almost circular and the strut is coupled to the tube with spherical element we can assume that the wheel can partially recover the camber angle variations caused by body roll. Although the kinematic properties of this suspension can be similar to a double wishbone suspension this kind of architecture had no industrial follow up. A different scheme of front independent wheel suspension is attributed to Dubonnet an important independent car designer and was exploited by many car manufacturers among them Fiat which applied this solution to production starting in 1935. The suspension includes a sealed bearing element cartridge that integrates the .
