3. Suspension is the springs and shock absorbers in a car that help it ride smoothly over bumps and rough roads. Imagine you're in a car and you drive over a bumpy road. Without suspension, you'd feel every bump super hard and it would be uncomfortable. But because of the car's suspension, the springs and shock absorbers help absorb those bumps, making the ride much smoother for you inside the car. WHAT IS SUSPENSION?

4. 1. Supports the weight of the car. 2. Provides a smooth ride 3. Allows rapid cornering without extreme body roll. 4. Keeps tires in firm contact with the road. 5. Allows front wheels to turn side-to-side for steering. 6. Works with the steering system to keep the wheels in the correct alignment. 7. Protects passenger and cargo from vibration and shock PURPOSE OF SUSPENSION

5. BASIC PARTS OF SUSPENSION 1.Ball Joints 1. Ball joints connect the suspension components, allowing swivel movement for steering and absorbing road irregularities. 2. Integral in various vehicles, ball joints aid in steering and suspension, ensuring maneuverability. 3. Facilitate smooth movement but susceptible to wear, affecting handling and potentially causing noise or instability. 2. Springs 1. Springs support a vehicle's weight, absorb shocks, and maintain ride height by storing and releasing energy. 2. Essential in diverse applications, springs are utilized in vehicle suspensions, mattresses, machines, and more. 3. Offer resilience and flexibility but may wear out over time, impacting performance and necessitating replacement.

6. BASIC PARTS OF SUSPENSION 3. Shock Absorbers 1. Shock absorbers control excessive motion by dampening oscillations, ensuring a smoother and more controlled ride. 2. Integral to vehicle suspensions, shock absorbers enhance stability and comfort across various terrains. 3. Improve handling and comfort, yet prolonged use may lead to reduced efficiency, requiring replacement for optimal performance. 4. Coil Spring 1. Coil springs store and release energy, supporting vehicle weight and absorbing shocks by compressing and expanding. 2. Widely employed in vehicle suspensions and various machinery due to their flexibility and resilience. 3. Offer efficient energy storage but can sag over time, affecting ride height and necessitating replacement for optimal performance.

7. BASIC PARTS OF SUSPENSION 5. Leaf Spring 1 . Leaf springs consist of multiple steel strips stacked and clamped together, forming a flexible suspension component. 2. Found in trucks, trailers, and some older vehicles, leaf springs handle heavy loads effectively due to their robustness. 3. They offer durability and simplicity but can provide a stiffer ride and may generate noise due to friction between the leaves. 6. Control Arm 1. Control arms link the suspension to the chassis, facilitating wheel movement while maintaining stability. 2. Bushings within control arms reduce friction, aiding in smooth suspension motion and absorbing road vibrations. 3.Crucial for precise handling, control arms and bushings enhance stability and steering responsiveness in vehicles. 7. Steering Knuckle 1. Steering knuckles connect the wheel hub to the suspension components, allowing wheel movement for steering. 2. Essential in the steering system, knuckles enable proper wheel rotation and support vehicle weight. 3. Steering knuckles significantly influence steering precision and stability, directly affecting a vehicle's maneuverability and control.

8. BASIC PARTS OF SUSPENSION 8. Torsion Bar 1. Torsion bars are a type of suspension element that store and release energy by twisting along their axis. 2. Utilized in some vehicle suspensions, torsion bars offer support and stability while absorbing road shocks. 3. Torsion bars affect ride comfort and handling, contributing to the vehicle's stability and overall performance. 9. Sway Bar 1. Sway bars, or stabilizer bars, minimize body roll by connecting suspension components, enhancing stability during turns. 2. Integral in vehicle suspensions, sway bars distribute weight evenly across wheels, improving handling. 3.Sway bars notably reduce body sway, ensuring better control and stability, especially during cornering maneuvers.

9. TYPES OF SUSPENSION Dependent suspension systems link the wheels, causing movement on one side to impact the other. Typically found in solid axles or leaf spring setups, they prioritize durability and simplicity, common in trucks and off-road vehicles. This design limits each wheel's freedom of movement, affecting overall traction and handling on uneven surfaces. Independent suspension systems allow each wheel to move independently, improving stability and handling. Employing mechanisms like MacPherson struts or double wishbones, this setup enhances comfort and traction on various terrains, commonly found in modern vehicles to offer better maneuverability and a smoother ride experience.

10. WORKING PRINCIPLE A vehicle's suspension system manages tire-to-road interaction using springs, dampers, and linkages. Springs absorb road shocks, while dampers control bouncing. Linkages connect wheels to the chassis, allowing vertical movement while ensuring stability. This system optimizes traction, comfort, and handling by reducing road impact, maintaining tire contact, and managing the vehicle's response to uneven surfaces for improved control and safety

11. WORKING PRINCIPLE AIR SUSPENSION Air suspension uses air springs instead of traditional coil or leaf springs. It relies on compressed air within the springs, adjusted by an onboard compressor and valves. Sensors monitor the vehicle's height and adjust air pressure accordingly, enabling variable ride height, improved comfort, and handling. This system adapts to different loads, terrain, and driving conditions for a smoother and more controlled ride.

12. CHECKING SHOCK ABSORBER CONDITION Bounce test - The bounce test assesses shock absorber condition by pressing down firmly on a corner of the vehicle. - Release the pressure and observe the number of bounces. - If the car bounces more than twice, the shock absorbers might be worn or faulty, indicating a need for replacement. - Repeat the test on each corner to evaluate the overall condition of the shocks.

13. CHECKING SHOCK ABSORBER CONDITION Leaking Shocks - Oil residue around shock absorbers indicates potential leakage. - Visible fluid leaks or puddles beneath shocks signify internal seal failure. - Leaking shocks compromise damping efficiency. - Reduced handling, longer braking distances, and discomfort can result. - Immediate replacement is crucial for safety and optimal suspension performance.

14. TIE ROD INSPECTION Inspect tie rods for wear or damage by: - Checking for excessive play or looseness when wheels are lifted. - Looking for worn-out or torn boots that protect the joints. - Assessing for rust, bends, or visible damage on the rod. - Verifying secure attachment to steering components. - Any signs of wear, looseness, or damage necessitate prompt replacement to ensure safe and precise steering.
