People's understanding of French cars, in addition to its "artistic" appearance, as well as widely acclaimed chassis technology, can be called a "wonderful flower" in the automobile industry. Even BMW is willing to pay for Citroen's PSS rear wheel steering technology. So why is there a saying that "every chassis should say Citroen"? And is the French car chassis technology represented by Citroen really that powerful?
First of all, as we all know, the most advanced technologies of many automobile manufacturers are basically put into major competitions first. Citroen's rich chassis technology is accumulated by various rally champions of Senna WRC, ZX Rally and DS3 WRC. Rally itself has very strict requirements for the chassis technology of automobiles, and Citroen's seven-crown champion is also the embodiment of advanced chassis technology.
It should be the sweetness of the track, so that French cars plunged into the adjustment of the chassis system, especially the suspension system, from the hydraulic-pneumatic linkage suspension of 1954 to the active hydraulic suspension of 1989 and then to the active anti-roll hydraulic suspension of 1994. Under the leadership of Citroen, French cars began to have "chassis masters", and there were also some cases in which luxury brands bought chassis patents from Citroen.
In recent years, many consumers have begun to understand cars and pay attention to their configuration parameters. Then the semi-independent suspension configuration of French cars has become a criticism of many consumers. However, I believe that friends who have taken French cars should have experienced it. Even the semi-independent rear suspension has the same comfort as the multi-link independent suspension. So where is the secret? There has always been a saying in the automobile industry about chassis adjustment, "seven-frame three-point adjustment". Therefore, although the Citroen model with semi-independent suspension is loaded, due to the high toughness of the whole vehicle frame, the overall center of gravity is stable and it is not easy to deform at high speed. This is another secret of French car chassis adjustment.
In recent years, with the development of mid-to high-end cars, Citroen began to introduce some mid-level cars of C5 and C6. Then naturally they can't walk the world by "semi-independence". And they use another magic weapon of French car chassis technology, such as the third generation C5, whose chassis technology has several characteristics:
First of all, it has Citroen's unique weapon-FML shock absorption toughness multi-link rear suspension. It's complicated to explain Simply put, this kind of rear suspension can minimize the deformation of the car body, ensure the suspension to run in the given position, and realize accurate control of the car body.
Secondly, it has a hydraulic buffer system to reduce the collision and vibration between the suspension and the frame. Compared with other models using rubber pads, the hydraulic system of French cars is relatively kind.
Thirdly, the installation method of rear suspension shock absorber and spring with a large inclination angle of nearly 45 degrees is also a unique weapon for French cars. This can decompose the vertical bump of the vehicle and strengthen the lateral stability of the vehicle body. In this way, the roll can be better controlled.
