Chassis components are the structural parts of a vehicle that support its weight and house various systems. Key components include the frame, which provides the main structure, and the suspension, which connects the wheels to the frame and absorbs shocks from the road. Other important parts are the axles, which transfer power from the engine to the wheels, and the brakes, which allow the vehicle to slow down or stop. In addition to these, the steering system is crucial for controlling the direction of the vehicle. The chassis also includes the body, which houses passengers and cargo, and the engine mounts, which secure the engine in place. Together, these components ensure the vehicle operates safely and efficiently.
