If you are a speed enthusiast or a drag racer you probably already know what a roll cage is.But if you don’t, you may be wondering what those are and what do they do. The concept is very simple: a roll cage it’s a metal exoskeleton you weld in the inside of your vehicle to hold it together in case of a crushing impact. Over the next lines we’ll get a glimpse of the Machining and Fabrication of such an intricate tech piece.
How does a roll cage work?
One of the first things almost everyone wonders about a Roll cage fabrication is the fact that it’s not a standard issue in the car industry. A roll cage is a metal construct that is designed to keep the driver of a vehicle alive as well as his companion if they get involved in an accident. The metal bars are set up in a special fashion that is designed to keep most of the internal structure of the vehicle intact.
An 8-point roll cage is usually composed of a hoop along both cage sides that go along an A-shaped pillar, a windshield frame that includes a brace that goes across the roof, and a back brace metal bar, gussets and struts for the subframe. 10 point cages offer a bit of an upgrade since the y go for rear struts and an X-bar between them for additional torsional support. The use of these devices is regulated by the National Hot rod Association and they are the only one who can sanction a racing car with roll cages (you can check out their website for more detail about the requirements).
What else do they do?
Roll cages are also placed in a vehicle to improve its structural strength. The car lined with a roll cage will be much more stable and it will remain still while planting tires on the ground or getting ready to roll. One could even say that the safety features are there to be used once, but the stability factors offered by the roll cage are present right there every time the vehicle is used. The extra points (or additional bars) that are added to a chassis construct will enhance this stability by making the car more rigid.
Are roll cages only for racers?
You may be asking yourself if using a roll cage in a vehicle is only restricted to drag racers. Of course the answer would be “no” but it’s important to take notice in the fact that a roll cage for a drag race car is not the same as one used on a city car, there is a few key differences between them in conception, and they all have to do with the fact that roll cages are usually destined to safeguard the life of a driver that is fully equipped with anti-crash gear such as a helmet and padding. A city car lined up with anything more than 8 bars could seriously hurt a driver instead of saving his life. (Automobile)
