9 Car Suspension Components and Their Functions
Cars can indeed run stably thanks to the systems that work in them. The suspension is one of the essential systems in a car so that it will have a bad impact if the suspension component is damaged.
The suspension system is a car chassis placed around the car body with the wheels. The suspension system is deliberately designed to anticipate the various surprises that an uneven road surface can cause.
With a suspension component, the car is more comfortable to drive. The suspension can also increase the grip-ability of a wheel to the road. At least there are several main functions of car suspension.
The suspension system's primary function is to reduce or absorb various car vibrations generated from the road surface. This will make the car passengers feel safe and comfortable in the car.
Not only that, this system can also move the braking system and motion to the car body using friction between the wheels and the road. The suspension can also support the car body on the axle and help maintain the body's geometric position with the wheels of the car.
The types of suspension systems in a car are different because it depends on the kind of car. Independent type has several kinds: Independent Type Trailing Arm Type, Macpherson Type, and Wishbone Type.
Rigid Suspension also consists of several types such as Balance Arm Type, Parallel Leaf Spring Type, and Trunnion Type 8. In comparison, the third type of suspension system is Special Suspension and Air Suspension to be examples of its kind.
In general, a suspension consists of several components in it, and each piece has various uses. Several types of cars have been equipped with multiple features to support the suspension system in them. The addition of components is usually to complement the needs of the car.
Springs are a significant component that has a critical role in a car suspension system. The primary function of springs is to absorb or dampen the various shocks generated from road friction with car wheels to not continue to the car body.
The springs also have a function to help increase the wheels' traction on the road, which will make the passengers feel comfortable in the car. If the vehicle does not have springs, of course, the car will not drive stably.
Types of springs in a car suspension include, among others, coil springs or coil springs, leaf springs or leaf springs, and torsion bar springs.
2. Shock Absorber
A shock absorber is a component of a car suspension that functions to dampen up and down movements or oscillations caused by springs that absorb various shocks or vibrations from the road surface.
In a Shock Absorber, there is a liquid that acts as a shock absorber oil. The Shock Absorber fluid will absorb the spring's oxylation through the resistance of oil flow in a small hole or orifice when the piston moves in a cylinder contained in the shock absorber.
The Shock Absorber works because when there is compression, the valve will open, and the oil will flow very easy to prevent damping. When expansion, the valve will close, and oil will flow in a small hole, causing damping.
Shock absorbers in a car are divided into several types. The shock absorber consists of a single type shock absorber and a double-acting shock absorber based on how it works.
Based on the construction, these components are divided into twin-tube and monotube types. Meanwhile, based on the working medium, the shock absorber consists of a shock absorber type containing gas and a hydraulic variety.
3. Ball Joint
The ball joint is a suspension component that functions to accept various lateral and horizontal loads on the car. The ball joint is also helpful as a rotation axis when the vehicle is turning. There are two main types of ball joints, namely upper ball joints and lower ball joints.
In a ball joint, you will usually find helpful oil for lubricating the various parts that rub against each other. If there is no oil, of course, the friction will not work correctly, and the ball joint will tend not to function optimally.
It is necessary to have the oil change at a specific interval in the molybdenum disulfide lithium ball joint. However, there is no need for grease to change in a ball joint with a resin holder type.
4. Stabilizer Bar
The stabilizer bar is a car suspension component that maintains body balance when the car turns. When the car turns, it will undoubtedly create a centrifugal force, which is the force from an object that turns or rotates to get out of the track.
When the car is used at high speed and suddenly turns the car, there will be a greater centrifugal force than when used at a low speed. The centrifugal force that is too large will usually make the car overturn if it turns suddenly at high speed. The stabilizer component will help to stabilize the car so that it doesn't turn over.
In general, the stabilizer is an iron rod connected or connected between the lower arm of the left and right wheels. In the middle, it will usually be connected to the car body. Stabilizer iron rods typically have reasonably high elasticity so that their performance follows the car's specifications.
A bumper is an additional component that is included in the suspension system. A bumper does consist of several parts, such as bounding and rebounding. Both are installed usually to protect the axle, frame, Shock Absorber, and others.
Protection will be carried out when the spring position is in a condition that is expanding and contracting beyond its maximum limit. This will prevent any damage to the bounding and rebounding components.
Bounding bumper will usually take effect when the car is shrinking, and bumper rebounding will affect it when the vehicle is inflated. The bumper is one of the additional components in the suspension system that has a significant role in the car.
The general public recognizes a bumper as a safety device installed on the back or front of a car. The shape of the bumper is also made in various variations, depending on the car's type and model.
6. Lateral Control Rod
The lateral control rod is one of the less well-known additional car suspension components, even though it is undoubtedly present in a four-wheeled vehicle or car.
The lateral control rod component functions to hold the axle when a load comes from the side. The lateral control rod is usually installed between the axle of the vehicle and the vehicle's body.
The lateral control rod component is essential because every car component must have a specific maintenance and repair period. If you have a car, it is critical to always pay attention to the various elements contained in the car. Do not let the components get damaged, which will hinder the performance of the car.
7. Upper and Lower Arm
The upper and lower arms are part of the suspension system, whose job is to connect the knuckle arm with the car body so that the wheels will be attached to the knuckle arm. Not all suspension systems will have an upper arm but will still use a lower arm.
The arms work like a human hand that can move up and down in a car suspension system. In mechanical terms, this component is known as a wishbone or a-arm. Upper and lower arms allow the car to turn stably.
8. Strut bar
The strut bar is a component in the car's suspension system that functions to hold the lower arm so that the front wheels can function correctly. At the steering wheel of a car, the steering wheel can turn on its own, and this condition usually occurs when the vehicle is in a straight position after turning.
The steering wheel turns quickly because the car's front wheel is designed with a tilt or often referred to as front wheel alignment. The adjustment on the front wheel is often known as the spooring process.
When the spooring process takes place, the adjustment will be made to the strut bar nut. The strut bar does function to prevent or keep the lower arm from moving forward or backward.
9. Knuckle Arm
The knuckle arm is a car suspension component that is positioned at the front of the car wheel. The wheels of the car will rotate continuously on the spindle shaft that comes from the knuckle arm. The knuckle arm component will also be connected to the lower arm using a ball joint.
The knuckle arm has an essential function, so it requires you always to maintain the car's suspension system. Ensure the car's condition in authorized workshops so that the inspection is carried out in its entirety and all suspension components that are badly damaged, of course, must be replaced immediately.
The best news for you, New Confero S, which is Wuling's newest product, uses the Independent Suspension system, which makes your trip even more comfortable. This family car from Wuling offers convenience via Independent Suspension on rear wheels.
