NOTE

SUSPENSION SYSTEM

A suspension system is a crucial component of a vehicle that helps absorb shocks and bumps from the road, providing a smoother ride and better handling.

It consists of various parts such as:

1. Springs: They absorb bumps and make the ride smoother.
2. Shock Absorbers: They control bouncing and keep the car stable.
3. Control Arms: They connect the suspension to the frame and help with wheel movement.
4. Struts: These combine springs and shock absorbers into one unit.
5. Sway Bars: They reduce body roll during turns.
6. Bushings: These absorb vibrations and allow for movement between parts.
7. Ball Joints: They connect control arms to the steering knuckles.
8. Tie Rods: They link the steering system to the wheels for steering control.

Types of suspension system

1. Leaf spring

2. Coil spring

1. A leaf spring is a type of suspension spring commonly used in older vehicles and heavy-duty applications. It consists of several layers or "leaves" of spring steel bound together to form a flexible arch-like structure. Leaf springs are durable and provide good load-carrying capacity, making them suitable for trucks, trailers, and commercial vehicles.

2. A coil spring is a type of suspension spring made from a single continuous coil of hardened steel or other materials. Coil springs are more compact and versatile than leaf springs, allowing for better handling and ride comfort in passenger cars and modern vehicles. They work by compressing and expanding as the vehicle travels over bumps, absorbing and dissipating energy to cushion the ride.

EVALUATION: 1. Define suspension system
