A chassis is defined as the most basic framework for a manmade structure. Electrical engineers use a chassis to support circuit boards. Another common type of chassis the understructure of a car, truck, or sport utility vehicle. At the most basic level, the chassis of an automobile consists of only the frame. Sometimes the chassis will include not only the frame, but also the wheels, transmission, and even the driver's side seat!
Needless to say, the chassis is an incredibly important portion of the car. As important as the chassis is, many drivers don't know much about it. A car chassis is the most integral component in the final construction of any motorized automobile apart from the engine itself. As well as act as the frame onto which all of the vehicle's parts are attached, it also provides invaluable structural integrity which prevents the car from collapsing into itself under large amounts of strain.
The most important feature of an automobile chassis is the way in which it anchors all of a car's key components, including the suspension system, wheels, and car body. Contrary to popular belief, the painted body that surrounds the exterior of the car is not actually a part of the chassis but another part that depends on the chassis to stay functional. If the chassis were weakened, it may play a huge safety risk for both the car and its driver. This is why it is important to ensure that your car is structurally sound every 6 months.
Safety in Rigidity
When involved in a wreck, the chassis is what helps protect the driver from their crumpling vehicle. Aside from the air bag and any other safety features, the structural strength of an automobile chassis is the largest deterrent of more serious automobile-related injuries.
