The double wishbone suspension was introduced in the 1930s. French car maker Citroën began using it in their 1934 Rosalie and Traction Avant models. Packard Motor Car Company of Detroit, Michigan, used it on the Packard One-Twenty from 1935,[1] and advertised it as a safety feature. During that time MacPherson strut was still in the area of ...
Pull-rod suspension and push-rod suspension refer to a specialised type of automotive suspension system which is largely based on a double-wishbone system, incorporating elements of the commonly used MacPherson strut. [1] In cars, suspension refers to the system by which the vehicle maintains contact between all of its wheels and the ground.
The double-wishbone suspension can also be referred to as ‘double A-arm,’ though the arms themselves can be A-shaped, L-shaped, or even a single bar linkage. The complete TAK-4 independent suspension system set-up also includes a subframe which contains the axle differential, half shafts, and wheel ends with steering attachments and brakes.

A similar method like this was used in the late 1930s by Buick and by Hudson's bathtub car in 1948, which used helical springs that could not take fore-and-aft thrust. The Hotchkiss drive , invented by Albert Hotchkiss, was the most popular rear suspension system used in American cars from the 1930s to the 1970s.
Cars that have cockpit adjustable ride height generally cannot have MacPherson struts because of the camber changes that are an unavoidable part of the design. Ride suffers because the shock absorber has almost the same vertical motion as the wheel, so there is relatively little leverage to break the stiction in the seals.
The shape of the subframe changed to an approximate triangle, bolted to the front of the differential and attached to the car at approximately the same points as the radius arms of the first generation IRS. The rear of the differential was further supported by a pair of link rods attaching it to the car's rear floor structure.
Chapman struts were introduced in Lotus' first single-seater car, the Lotus Twelve. [10] This was developed as a 1.5-litre Formula 2 in 1957, but re-engined in 1958 it also competed in Formula 1. [10] This same car also introduced Lotus' wobbly-web wheel. [11] There were two differences from these precursors to the Chapman strut.
