The single-tube design uses a free piston to separate the oil chamber from the air chamber in the housing. No matter what your purpose is in using a car, we hope you can get maximum comfort and safety out of it. Shock absorbers play an important role in this regard. In automobile history, there have been many different shock absorber designs. There are many rumors and discussions about which type of shock is better, single tube or double tube? Single tube and double tube are called two different types of suspension systems and they work in different ways.
In a single tube shock absorber, the components of the shock absorber are contained in the tube. The single tube system consists of a shell that functions like a cylinder. Inside the cylinder, you will find a piston and a gas valve. Compared with the double-tube design, the single-tube structure also includes some differences. The single-tube design uses a free piston to separate the oil chamber from the air chamber in the housing. The single tube is more durable and requires minimal maintenance, but is more expensive than the double tube.
Also, single tube shocks tend to be harder due to high pressure gas injection. It is also difficult to maintain a sufficient stroke due to the location of the air chamber and oil chamber. Therefore, the advantages of a single tube are suitable for hard disk in the circuit. The big problem with the single tube is that if the housing consisting of one cylinder is damaged, the damper will no longer be able to move. This often happens when driving on ordinary roads or off-road, because you never know what might happen to its surface.
In the double-tube shock absorber, there are 2 cylinders: 1 cylinder is placed in the housing, and the second cylinder contains a piston valve, which moves up and down in the second cylinder and is called “cylinder internal”. With a double-pipe design, there is no piston or barrier between the oil chamber and the air chamber. This uses two-tube dampers to provide a more comfortable ride experience, eliminate the load on the seals, and reduce friction caused by low air pressure. Single tube shock absorber or double tube shock absorber-which one is more suitable for your car? Let us take a closer look at the difference between single-tube and dual-tube shock absorbers. Then you can decide which type to use to replace the vehicle’s shock absorber.
Here are some things to consider.
Ride quality is usually the first factor people consider when deciding which shock absorber to buy. One of the main functions of the shock absorber is to cushion the impact of drops and bumps on the road while driving.
Response is another important consideration. This is essentially a measure of your impact to the road conditions and speed. Ideally, your suspension should remain stable on smooth roads and stiffen in rough terrain or high performance situations.
When the damping force is stable, you will have a responsive, high-quality ride. What does this mean? This means that the pressure inside the impact is evenly distributed. Due to several aspects, single-tube shock absorbers provide better damping than double-tube shock absorbers.
Easy to install
Ease of installation is an important consideration when looking for performance shocks or struts. If you install them yourself, simpler is always better. If you plan to install them in a store, a simpler installation will save you a lot of store expenses. This is one of the few reasons why single-tube shock absorbers are becoming more and more popular. They have a separate housing for the piston valve, hydraulic oil and pressurized gas. This means that it is simpler and easier to install than double-pipe products that require more effort and precision.
One of the biggest obstacles to the impact is aeration. Considering that the equipment contains oil and natural gas (oxygen or nitrogen), the two products always has the opportunity to mix. When this happens, the vibration will have the same effect on the brake tube with air bubbles inside. This typically results in poor damping and damping, especially after high performance or driving on rough roads.
Fading is a common problem affecting the shock and the entire suspension system. Continuous application of pressure to the shock absorber may decrease the performance of the accessory. This may be because the liquid creates bubbles and therefore foams, the piston may weaken and allow some pressure to escape between the two, or the heat may cause the chamber to expand. As we all know, fading has a greater impact on double tube impact than single tube impact. This is due to several factors. One, the surface of the piston is much smaller.
From the above comparison, single-tube shock absorbers have advantages over two-tube shock absorbers.
Monotubes provide better response, are easier to install, can be installed from different angles, and do not produce foam. Also, the opportunity for aeration is very small. Compared to the double tube, the single tube has superior damping capacity and provides better ride quality. In fact, single tube impact is more expensive than double tube impact. However, the benefits of installing these dampers greatly outweigh the cost. Plus, the single tube is more durable, requires minimal maintenance, and costs much less in the long run.
When buying shock absorbers, quality is the key. Be sure to choose a brand and company that provides a lifetime warranty. The disadvantage of dual-tube shock absorbers is their design features that do not allow them to be installed on strut suspensions. In addition, the air chamber and the oil chamber are combined, so you can often find aeration. In addition, the double-tube design is cheaper than the single-tube design.
