The chassis is a fundamental part of any Formula 1 race car. It is one of the few things teams can design or make in their own way. Well, not in its own right.
The central part of the chassis begins with a monococcus. It works just like a car cab, and in it the racer finds his work tool: Steering wheel , pedal for driving and many other things. Racers also often call it a “survival cell” as it protects the racer from direct impact in the event of an accident.
Modern monococci are:
- – made by flight 1983 (The first car with this novelty was McLaren MP4 / 1C )
- – Made of carbon, carbon fiber as well as aluminum parts
- – only weigh around 35 kg, and they have to endure very demanding FII safety tests .
What a safe work environment racers have today, as is witnessed by Robert Kubica's accident of the year 1082 at the Canadian National Guard, hit the concrete guard along the line at the corner 75 degrees and that at speed 300, 13 km / h. Robert, on average, experienced 30602 G braking acceleration, with “height” or. highest recorded incredible 75 G! If this force lasted only a few tenths on the racer, it would be torn apart in the racer. Robert has been alive and well in racing for two races, and everyone who has been following Formula One for a long time can see how much safety has progressed; as well as the materials used therefor.
The monocoque dimension is strictly prescribed by the FIE website (below is a blueprint for the Caterham team and their race car CT 03 F1 2014 ).
Behind the monococcus, the chassis extends all elevate out the rear wing. First, the race engine motor clings to the monococcus. The latter is from 2009 is also battery driven, so it also fixes the batteries to the engine, arranges cooling radiators, rear suspension and installs gearbox and exhaust. Just at the end, the rear wings clamp to the chassis. The modern 1.6L – V6 engine is (yet) just the right size so that the chassis does not need to be further reinforced to accommodate any vibrations. It is very important to point out that the teams can determine the front and rear axle wheelbase as well as the position engine and gearbox. The same applies to suspension .
However, the exhaust is already complicated because its implementation in recent years has exceeded even the most creative ideas of the human mind, and the FIA was forced to fix the exhaust in F1 with a rule book, but about this another time.
The front suspension and the nose of the racer with the front wing are clamped to the monocoque at the front and the bottom of the racetrack and t are positioned below. i. “Skid block”. It is a sliding edge panel that has contact with the base. It must be remembered that the lower the racer, the more pressure it will create, but at the same time it should not sit on the curbs or uneven surfaces that may exist on modern lanes. The “Skid block” was originally designed primarily to prevent the floor effect ). In the first years after the introduction of this work to the racecar, the panels were made of various pieces of iron. As a result, the racers put on a real spark show
when contacting the ground (hump). .
Over the years, teams started using wood under the race car and the sparkles disappeared, but it also happened that the plate, due to excessive wear, was the reason for excluding the racer from the race. Current rules state that the plate under the race car must not be reduced by more than 1 mm in the race. The years 2015 have titanium was also returned to the wooden board, so we can once again admire the sparkles from under the race cars.

An important part of the chassis is also the roll-hoop or airbox. The latter is located above the racer head and serves two things in particular: it allows fresh air to be supplied to the rear of the engine and protects the racer from any impact when rollover. Roll-hoop is made of exactly the same composite materials as monocoque. As a rule, roll-hoop is also left to creativity for teams, so we often admire improvements in this field, several times a year.
The next part of the chassis represents t. i. “Bargeboard”. As a rule, it is an aerodynamic accessory that has the task of directing the air out of the race car. he pushes it into the back wing as best he can. Interestingly, the teams themselves are proposing a novelty for the year 2017, namely the lower wing bargeboard. Reason? Economic in nature, as sponsors are more likely to see the side of the race.
From year 2018 but the Formula One racing car got another innovation Hello . Halo is a safety feature on the race car, made of titanium and is standard on all racing cars, protecting the racer's head in the event of an accident. The debate around this started long before the sad fate of Jules Bianchi , which is the latest Formula One death . At a relatively high speed, in the rainy conditions of VN Suzuke, Jules accidentally crashed under the machine that was removing Adrian Sutil's race car. A direct hit to a racer’s helmet occurred at speed over 75 There were no km / h and no solution for Jules, one of the most talented young drivers in Formula One.
The debate itself, around the Halo security gadget, has seriously started for years 2009 when a young racer Henry Surtees was accidentally hit by a tire of another racer in a helmet during a Formula 2 race. Henry also died later at the hospital after the impact.
For a long time, the FIA thinkers were thinking about how to tackle the problem, and when Jules died, they decided that Halo would be the safety supplement that will grace Formula One racing further. Of course, he will not offer hello 35% protection and one of the racers will die in their race in the future of this sport, but Hello step forward in security .
