Understanding the Suspension System: Components and Function
Springs: Coil Springs: These are helical-shaped springs made of steel that support the weight of the vehicle and provide cushioning against bumps. Leaf Springs: Consisting of multiple layers of flexible metal strips (leaves), these springs are commonly found in rear suspension systems of trucks and SUVs. Air Springs: These use compressed air to support the vehicle's weight and provide adjustable suspension stiffness. Dampers (Shock Absorbers): Hydraulic Shock Absorbers: These devices use hydraulic fluid and a piston to absorb and dampen the vibrations and impacts from the road. Gas-filled Shock Absorbers: These shock absorbers contain nitrogen gas, which helps prevent foaming of the hydraulic fluid and maintain consistent damping performance. Anti-roll Bars (Sway Bars): Front and Rear Anti-roll Bars: These bars are typically connected to the suspension on both sides of the vehicle and help reduce body roll during cornering by transferring force between the wheels.
