Chassis is considered as one of the main structures of the car. It is usually made of steel frame and supports the body and engine of the car. To put it simply, car chassis or car frame is the skeleton that brings together many components such as engine, tires, brakes, steering gear and drivetrain.
The chassis provides support and rigidity to the vehicle. The chassis usually consists of a series of cross members that cross a pair of long cables and channels. The cross members have a small cross section to provide long storage space. The safety of the chassis is an important part of the design and must be considered at every stage.
To meet the increased strength requirements of high-performance sports cars, the tubular space frame chassis usually has a strong structure under the two doors. Compared to ladder and monocoque chassis of the same weight, the tubular space frame chassis is very strong in all respects.
The tubular part of the chassis uses a large number of circular tubes (sometimes square tubes are used to allow easy connection to the body panel, but the cross-sections provide the highest strength), arranged in different directions to protect against the forces from all sources of energy.
