Chassis and Suspension

The chassis and suspension are the foundation of a car, responsible for providing structural integrity, handling, and ride comfort. Together, they connect the body to the wheels and absorb road imperfections, ensuring a smooth and controlled driving experience.

Chassis⁚

• Frame⁚ The primary structural component of the chassis, typically made of steel or aluminum, providing a rigid foundation for the entire vehicle.
• Subframes⁚ Smaller, independent frames that attach to the main frame, supporting specific components like the engine, transmission, and suspension.
• Body Mounts⁚ Points where the body is attached to the chassis, allowing for a degree of flexibility and isolation from road vibrations.

Suspension System⁚

• Springs⁚ Coil or leaf springs that absorb shock and provide vertical support, maintaining ride height and controlling body movement.
• Shock Absorbers (Dampers)⁚ Hydraulic components that control the rate of spring compression and extension, reducing oscillations and providing a smoother ride.
• Control Arms⁚ Lever arms that connect the wheels to the chassis, providing lateral stability and controlling wheel movement during cornering.
• Sway Bars (Anti-Roll Bars)⁚ Rigid bars that connect the control arms on opposite sides, reducing body roll during cornering and improving handling.
• Steering Knuckles⁚ Components that connect the steering linkage to the wheels, allowing for steering input to change the vehicle’s direction.
• Tie Rods⁚ Metal rods that connect the steering knuckles to the steering rack, transmitting steering input to the wheels.
