Parts Of A Car’s Suspension System

What are the parts of a car’s suspension system?

  1. Frame
  2. Wheels and Tires
  3. Anti-Sway Bars
  4. Spring
  5. Shock Absorber
  6. U-bolt
  7. Bushes

 

Many people talk about engine power and car aesthetics. But without a suspension system, a vehicle wouldn’t be able to maintain a smooth ride over rough terrain or even carry heavier loads. It would easily sway, roll out of balance, and become unresponsive to commands. That’s why it is useful to learn about the parts of a car suspension system. Read on!

 

Frame

Frame

The frame is the skeleton that supports the load of a whole car. Think of it as the foundation, where the whole vehicle with its engine, chassis, seats, and all the interior parts are carried.

In addition to this, the suspension system also matters when it comes to securing your car’s load. If you put too many objects inside your car that exceeds its capacity, the frame would undergo wear and tear.

 

Wheels And Tires

If only the road was composed of a flat surface without bumps and cracks, then all you would need are wheels and tires. These parts of the suspension system are the first ones to take the hit whenever you drive over rough terrain.

Wheels or rims are the parts of a vehicle that allows your car to move. The bigger the rim, the higher the leverage your car has. As for the tires, they deform slightly when your car goes over slight bumps on the road. This helps reduce the shock to the suspension system.

 

Spring

Spring

Whenever you go over big humps, your car’s springing system reduces the impact. This decreases the bouncing motion which could damage your car. It also helps the car carry heavy loads to prevent the axle from breaking. With the right springs, you will experience a smoother ride.

There are different types of springs used in vehicles. Leaf springs are consist of stacked leaves that slightly bend inward in an arc shape. These are mainly used in heavy-duty cars and trucks with heavy loads.

There are also coil springs that compress and expand to reduce impact and torsion bars that twist for the same reason. Another type is the air spring which has cylindrical chambers of air to absorb shock.

 

Shock Absorber

With a springing system alone, your car will bounce up and down until all the energy absorbed by the spring is gone. That’s why you need an additional component to absorb the impact and dampen the vibrations. This is where the shock absorber is used.

By turning the kinetic energy into heat energy, the shock absorber reduces the spring suspension movement. It is able to ensure that your car’s wheels and tires maintain contact with the road at all times even if you experience bumps.

 

Anti-Sway Bars

Also called anti-roll bars, these cylindrical rods span the length of your axle. It is a u-shaped metal that limits the swaying action whenever your car becomes out of balance. Whenever your car rolls excessively it becomes unresponsive temporarily. This can be unsafe and cause accidents.

The anti-sway bar improves your control whenever you are steering your vehicle. If you have one, the ability to turn into corners is also enhanced.

 

Bushes

These are the smaller components of your car’s suspension system that connects it all together. It needs to be flexible and allow a little bit of movement, while still fixing the parts into place.

Bushes are available in different sizes, and the most common material it is made of is rubber. To prolong its life, it is replaced by polyurethane ones.

 

U-bolts

U-bolts

To keep leaf springs in place, a component such as the u-bolt is used. It is a u-shape steel rod with threaded ends similar to a screw. This allows it to connect to bolts to keep an object fixed.

The u-bolt also helps to reduce the amount of flexing of the leaf spring which could lead to early breakage. It does this by eliminating the stress that can build up on the holes of each leaf whenever a force is applied to it. A u-bolt is available in round bend, semi-round bend, and square bend depending on the design of the suspension.

 

Key Takeaway

The different parts of a car suspension system are the frame, wheels, tires, anti-sway rods, spring, shock absorber, u-bolt, and bushes. With all of these in place, a vehicle’s load will be supported properly reducing bouncing and swaying. It also results in a smoother ride even if you drive over bumps and humps on the road.

Roberts is one of the leading suppliers of automotive and industrial parts in the country. Automotive OEMs like  Mitsubishi Motors Philippines, Toyota Motors Philippines, Isuzu Motors Philippines have consistently trusted it for its leaf springs and other vehicle components.

Roberts also supplies the Tiger U-bolt. It has high tensile strength, hardness, and extended life compared to its competitors. If you have any questions and inquiries, you can send a message here.
