What Does a Car Suspension Do?

Car suspensions are designed to help maximize the amount of friction between the tires and the road.

• absorbs the energy transferred through your car’s wheels

• helps the car cabin to ride atop the suspension relatively smoothly, even when riding on imperfect roads

Main Car Suspension Parts including:

• Coil springs: Coil springs are parts that help absorb impact when a car is driven over bumps, helping to absorb the motion of the wheels.

• Shock absorbers: These parts work alongside the coil springs and help control the impact from them. Shock absorbers also help ensure that tires are in contact with the road's surface.

• Struts: These are structural parts of the suspension. Struts often combine several suspension parts in one assembly, which include shocks and coil springs.

• Control arms: Control arms are links that connect the frame of a vehicle to the steering knuckle or wheel-hub assembly. They move up and down alongside springs when a car goes over a bump or other hazard, helping the tires maintain contact.

• Ball joints: Ball joints areimportant parts that help the vehicle turn left and right for turns. They also help the control arms with their up-and-down motion.
