What is the Role of a Car Chassis in an Automobile?

[IvanAnn]

The role of a car chassis in an automobile is to support and mount the car engine and its various components and assemblies, forming the overall shape of the vehicle. It also receives the power from the engine to enable the car to move and ensure normal operation. The car chassis consists of four main parts: the transmission system, the running system, the steering system, and the braking system. The transmission system ensures the necessary traction, speed, and coordinated changes between speeds under various driving conditions. The running system converts the torque from the transmission system into the driving torque for the car's movement through the adhesion between the wheels and the road surface. It also supports the total mass of the vehicle, mitigates impacts, reduces vibrations, and ensures driving stability. The steering system allows the driver to control the vehicle's direction as intended and includes specialized devices that generate braking force. The braking system enables the moving car to decelerate, stop, and maintain a stable speed when going downhill.
