It comes in various forms, including steam engines, internal combustion engines, electric motors, nuclear energy, etc. The development of the power system also reflects the progress of human civilization. The era of using steam engines as power systems has long passed. In modern society, the power systems of cars are mainly internal combustion engines and electric motors, with internal combustion engines still playing a dominant role and being more common, though their structure is relatively complex. Car chassis: The chassis is responsible for transmitting and distributing the power from the power system according to the driver's requirements, enabling functions such as acceleration, deceleration, steering, and braking. Its basic hardware components include the transmission, drive shaft, suspension components, steering mechanism, braking mechanism, etc.
