9 Car Suspension Components and Their Functions

A suspension, in general, is made up of several components, each of which serves a different purpose. Several car models have been outfitted with numerous features to support the suspension system. The addition of components is typically done to supplement the needs of the vehicle.

Car Suspension Components and Their Functions

  • Spring

Springs are an important component that plays an important role in a car suspension system. Spring’s primary function is to absorb or dampen the various shocks generated by road friction with car wheels so that they do not continue to the car body.

The springs also help to increase the traction of the wheels on the road, making the passengers feel more at ease in the car. Of course, if the vehicle lacks springs, it will not drive steadily.

Types of Variable Force Spring in a car suspension include coil springs or coil springs, leaf springs or leaf springs, and torsion bar springs, among others.

  • Shock Absorber

A shock absorber is a car suspension component that dampens up and down movements or oscillations caused by springs that absorb various shocks or vibrations from the road surface.

There is a liquid in a shock absorber that acts as shock absorber oil. When the piston moves in a cylinder contained in the shock absorber, the Shock Absorber fluid will absorb the spring’s oxylation through the resistance of oil flow in a small hole or orifice.

The Shock Absorber works because when there is compression, the valve opens, allowing the oil to flow freely and preventing damping. When the valve closes due to expansion, oil flows through a small hole, causing damping.

There are several types of shock absorbers in a car. Based on how it works, the shock absorber is divided into two types: single-acting and double-acting.

These components are classified as twin-tube or monotube based on their construction. Meanwhile, shock absorbers are classified into two types based on their working medium: gas shock absorbers and hydraulic shock absorbers.

  • Ball Joint

The ball joint is a suspension component that accepts lateral and horizontal loads on the vehicle. When the vehicle is turning, the ball joint also serves as a rotation axis. Upper ball joints and lower ball joints are the two main types of ball joints.

Oil is commonly found in ball joints to lubricate the various parts that rub against each other. Of course, if there is no oil, the friction will not work properly, and the ball joint will not function optimally.

The oil in the molybdenum disulfide lithium ball joint must be changed at regular intervals. In a ball joint with a resin holder, however, there is no need to change the grease.

  • Stabilizer Bar

The stabilizer bar is a car suspension component that keeps the body balanced as the vehicle turns. When the car turns, it will undoubtedly generate centrifugal force, which is the force produced by an object that turns or rotates to exit the track.

When the car is used at high speeds and sudden turns, the centrifugal force is greater than when it is used at low speeds. A large centrifugal force will usually cause the car to overturn if it makes a sharp turn at high speed. The stabilizer component will aid in the stability of the vehicle, preventing it from rolling over.

In general, the stabilizer is an iron rod that connects or connects the lower arms of the left and right wheels. It is usually connected to the car body in the middle. Stabilizer iron rods are typically fairly elastic, so their performance matches that of the vehicle.

  • Bumper

A bumper is an extra component that is part of the suspension system. A bumper is made up of several components, including bounding and rebounding. Both are typically installed to protect the axle, frame, Shock Absorber, and other components.

When the spring position is expanding and contracting beyond its maximum limit, protection will be applied. This will protect the bounding and rebounding components from damage. If any problem is caused so contact Constant Force Spring Manufacturer.

When the car shrinks, the bumper bounding takes effect, and when the vehicle is inflated, the bumper rebounding takes effect. The bumper is one of the additional suspension system components that play an important role in the car.

A bumper is a safety device that is installed on the back or front of a vehicle. The shape of the bumper also varies depending on the type and model of the car.

  • Lateral Control Rod

Even though it is undoubtedly present in a four-wheeled vehicle or car, the lateral control rod is one of the lesser-known additional car suspension components.

When a load comes from the side, the lateral control rod component holds the axle in place. The lateral control rod is typically installed between the vehicle’s axle and the body.

Because every car component has a specific maintenance and repair period, the lateral control rod component is critical. If you own a car, you must always pay attention to the various components of the vehicle. Do not allow the components to become damaged, as this will impair the vehicle’s performance.

  • Upper and Lower Arm

The upper and lower arms are components of the suspension system, which connects the knuckle arm to the car body, allowing the wheels to be attached to the knuckle arm. Although not all suspension systems have an upper arm, they all use a lower arm.

In a car suspension system, the arms function similarly to a human hand that can move up and down. This component is known as a wishbone or an a-arm in mechanical terms. The upper and lower arms allow the vehicle to turn steadily.

  • Strut bar

The strut bar is a component of the car’s suspension system that holds the lower arm in place so that the front wheels can function properly. The steering wheel of a car can turn independently, 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 has a tilt, also known as front wheel alignment. The process of adjusting the front wheel is commonly referred to as spooring.

When the spooling process is completed, the strut bar nut will be adjusted. The strut bar serves to prevent the lower arm from moving forward or backward.

  • Knuckle Arm

The knuckle arm is a car suspension component located in front of the car wheel. The car’s wheels will spin indefinitely on the spindle shaft connected to the knuckle arm. A ball joint will also connect the knuckle arm component to the lower arm.

Because the knuckle arm serves an important purpose, you must always keep the car’s suspension system in good working order. Ensure the car’s condition in authorized workshops so that the inspection is completed completely, and all suspension components that are badly damaged must, of course, be replaced right away.

The best news for you is that the newest product employs an Independent Suspension system, which enhances the comfort of your journey. This suspension car provides convenience with Independent Suspension on the rear wheels.

Independent Suspension has a one-of-a-kind design for driving comfort. The left and right rear wheels are not directly connected but are connected to the axle joints. To avoid cars rocking or crossing holes. Not only drivers, but also passengers in the back seats, will feel at ease.

Conclusion

If you discover various problems with your vehicle’s suspension system, you must immediately inspect the vehicle’s condition so that it can be dealt with directly. You must also use genuine car spare parts and avoid using imitations or counterfeit products. The condition of a vehicle’s suspension has a significant impact on its comfort.

The number of Indonesians who own cars is growing, and the types of cars available are diverse. However, few people understand the significance of suspension in a car. Beginners should always pay attention to and regularly inspect car suspension components.

This is a detailed examination of the suspension components and their functions in the vehicle. Hopefully, all of the discussions in the article will be beneficial to all of us.
