How the car’s suspension works
When people think of car performance, they usually think of horsepower, torque and acceleration from zero to 100. But if the driver can not control the car, all the power generated by the piston engine is useless. For this reason, automotive engineers turned their attention to the suspension almost as soon as they mastered the four-stroke internal combustion engine.
The job of the car is to maximize the friction between the tires and the road surface, to stabilize the steering wheel with proper handling and to ensure the comfort of the passengers. In this article, we will look at how a car suspension works, how it has evolved over the years, and where the design of the suspension will lead in the future.
Suspension is not necessary if the road is perfectly smooth and without any irregularities. But the roads are not far away. Even newly paved highways have subtle flaws that can interact with car wheels. It is these defects that give power to the wheels. According to Newton’s laws of motion, all forces have both magnitude and direction. A bump on the road causes the wheel to move up and down perpendicular to the road surface. Its magnitude, of course, depends on the wheel hitting a giant bump or a small one. In any case, the car wheel experiences vertical acceleration when passing through the defect.
Without an interfering structure, all the vertical energy of the wheel is transferred to the frame, which moves in the same direction. In such cases, the wheels can be completely disconnected from the road. Then, under the force of downward gravity, the wheels can hit the road surface again. What you need is a system that absorbs the energy of the vertically accelerated wheel and allows the frame and body to move smoothly while the wheels follow the ridges of the road.
The study of working forces on a moving car is called vehicle dynamics, and you need to understand some of these concepts to understand why suspension is essential in the first place. Most car engineers consider the dynamics of a moving car from two perspectives:
Ride – The ability of a car to clear a bumpy road
Handling – the car’s ability to safely accelerate, brake and turn
These two characteristics can be described in three important principles – road isolation, road holding and winding. The table below describes these principles and how engineers try to solve the specific challenges of each.
The car suspension system, with its various components, offers all the described solutions.
Let’s look at the parts of a typical suspension, from the larger chassis image to the individual components that make up the proper suspension.
Car suspension repair parts
The car’s suspension is actually part of the chassis, which includes all the important systems that are located under the car body. Such as Metal Head, Rubber Sleeve(rubber bellow, rubber bladder, rubber airbag), Dust Cover Boot, Copper air valve, steel clamps, aluminum cover(can), Shock Pressure Relief Valve, Shock Inside Buffer Stop, Aluminum or metal inside Piston and other air suspension fix parts.
