Car Suspension system is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows comparative motion between the two. Car suspension systems must support both road holding/handling and ride quality, which are at odds with each other. The tuning of car suspension system involves finding the right compromise. It is important for the suspension to keep the road wheel in touch with the road surface as much as possible, because all the road forces acting on the car do so through the contact patches of the tires. The car suspension system also protects the car itself and any luggage from damage and wear. The design of front and rear suspension of a car may be different.
How does car suspension system works?
If the roads of the area were perfectly level, a car suspension system in car would not be required. But as we all know, the roads are anything but level. Even the various highways have divots and bump that when interacting with the wheels can result in the car being jogged up and down. Void of a car suspension system the bumps would directly impact the car’s frame. The wheels of the car would lose connection with the street and slam back onto the street surface, leaving the car’s occupants with a ride similar to riding in a toy wagon. But fortunately, the car suspension system of a car moves the car smoothly forward while the tires follow the bumps in the road.
Components attached with car suspension system
Car suspension system absorbs bumps in the road to provide a pleasant driving experience. It allows the tires and brakes to work as they should to keep you and your passengers safe.
Here are the many components that works together to give you a smooth ride:
Most vehicles have four springs that soak up bumps and get the tire back in contact with the road quickly. They’re usually designed to last as long as your vehicle does.
Ball Joints & Spindle
Ball joints connect to the spindle via control arms. They allow the car suspension system to move up and down in conjunction with the road. The spindle is the rotating center point for the wheel and rotor.
Car shocks reduce oscillation. They use fluid and internal passages to dampen the springs and control movement. Shocks degrade, leak fluid, or sustain valve damage over time.
Struts combine springs and shocks into one unit. The strut is a more advanced version that also functions as the car suspension system’s upper pivot point.
The sway or roll bar counteracts forces that roll your car to the outside of a turn. This keeps the inside wheel connected with the ground.
Maintenance of car suspension system
As the car suspension system’s main job is to absorb shock in order to protect the vehicle and its occupants, parts are built to be fairly durable. There are a few other components on modern vehicles that are as over-engineered as those found in the car suspension system.
Still, with so much movement and force happening within the car suspension system, parts inevitably wear out or become damaged. Serious potholes can even bottom the car out so badly that the towers holding the springs in place bend or break.
Squeaking noises usually accompany bushings and other connections failing. If one corner of the vehicle becomes too bouncy when going over bumps, then have the shock absorbers or struts inspected right away. Problems with the suspension should be addressed immediately, so if the handling or shock absorption in a vehicle changes it should be inspected as soon as possible.
