Series Chassis with Pushrods?
According to the tyre designation '335/30 ZR20' it can only be a top-class sports cars. Assuming a planned series of suspension, then with the pushrod will clearly entered new territory with a few exceptions such as the
Lamborghini Aventador.
With the 'pushrod' is actually not meant the spring/damper element but the rod linkage connection, the so permits an almost horizontal position. But why one relocates spring and damper actually upward in the horizontal?
The picture clearly shows: Instead of the quite heavy spring/damper elements, for the unsprung masses remains only a connecting rod (arrow) subjected to pressure, upwards for deflection. Everything else is now part of
the sprung masses.
In Formula One racing car such a design still makes the most sense because the handle with the lowest possible own weight and in relation to it, on the unsprung masses attention must be paid even more. But the
chassis shown above seems to be a little different than the pure sports suspensions.
It is already clearly a sport suspension, none that can be switched to comfort while driving. The damper has neither an electrical connection nor an additional outer casing, which can take up mechanisms for damping
control. Instead it carries a thread with nut (arrow), which makes possible an adjustment of the chassis height.
Although it is a construction with double wishbones, which would be steerable in principle, we must emanate from a rear axle, of course driven. The fifth link (top picture, arrow) ends as if it would attached at prepared
grommets on the vehicle floor. It will probably used to produce a steering effect for the rear wheel when deflecting or rebounding.
Especially much spring deflection, the vehicle can not have. Therefore, probably the rather large difference between the wishbone above (1) and below (2). This results in quite significant changes in direction toward
negative camber both during deflection and during rebounding. The effect still will exacerbated because in this case both enlarge their distance from each other towards the wheel.
The brake disappears not only case of such wide tyres completely in the wheel. No wonder that one still has to give it cooling, at least by one additional air duct. The significantly worse drag coefficient of such sportier
versions has its origin also and not least in the increased demand for cooling air. 11/15
