What is automobile suspension? How many types of automobile chassis suspension are there?

The car suspension is a part of the chassis, which plays the role of connecting the car body and wheels, so as to ensure the stable driving of the car. So what exactly is the car suspension? What are the types?

What is car suspension?

The suspension is one of the assemblies of the car. It is mainly used to connect the car body and the wheels elastically. Its core functions are to transfer torque and mitigate impact. Because the car has a suspension, the wheels can also ensure good handling stability when driving on uneven roads.

Specifically, suspension is divided into independent suspension and non-independent suspension.

The left and right wheels of the independent suspension are not on the same axle. Each wheel is connected to the body with a separate suspension, so each wheel can move up and down independently. Most of the front and rear suspensions of cars are independent suspensions, but off-road vehicles and buses will choose to use independent suspension structures only on the front suspension and non-independent suspension on the rear suspension. That is, the left and right wheels are connected with a rigid shaft and connected to the body through the suspension. This makes the front wheel alignment parameters caused by the up and down bouncing of the wheels small and the tire wear is small. Of course, the spring is also harder.

Common problems during the use of suspension are abnormal noise, unstable vehicle driving or abnormal tire wear, too hard ride, etc. This may involve incorrect tire inflation pressure, shock absorber damage, elastic wear of elastic elements, need for replacement, etc. Please go to the maintenance point for inspection and confirmation.

There are several types of automobile chassis suspension

Automobile suspension can be simply summarized into two types: independent suspension and non-independent suspension. The specific subdivision types require the front and rear suspension to be separated.

The front suspension is basically independent suspension. Common types include: McPherson suspension, upgraded double wishbone independent suspension (also called double A-arm independent suspension), multi-link independent suspension, double ball joint spring shock strut suspension. The main type is still McPherson.

There are many types of rear suspension, the most popular of which are multi-link independent suspension structure and swing arm suspension.

Non-independent suspension, the more common types include torsion beam, integral bridge, etc. The advantages of this type of suspension are strong load-bearing capacity and high rigidity. Generally, medium and large MPVs and passenger and freight vehicles will adopt this structure.

What are the components of automobile suspension?

The components of the suspension system include shock absorbers, swing arms, stabilizer tie rods, ball heads and other parts.

The function of automobile suspension:

1. The connection between the car body and the wheels relies on the suspension system, which is used to transmit the force of the wheels.

2. It can be seen from its components, shock absorbers and stabilizer tie rods, that the suspension system can alleviate vibrations and impacts to ensure driving comfort and stability.

So please pay attention when using:

1. Do not overload to avoid damage to suspension components and pose a threat to personal safety.

2. If any parts are found to be damaged, such as oil leakage from the shock absorber, loose ball head, etc., they should be repaired in time to ensure good handling stability.

3. Slow down when passing various uneven roads. If the speed is too fast and the impact force is great, it will affect the service life of various components of the suspension system.
