Is the semi trailer suitable for installing hydraulic retarder?

With the continuous development of the transportation industry, vehicle technology is also improving, more and more new accessories gradually appear in people's eyes, hydraulic retarder is one of them.

Hydraulic retarder is a vehicle retarder that reduces vehicle speed through hydraulic device, also known as hydraulic retarder. For example, when the vehicle is in the long slope, although it can receive good braking effect through exhaust braking, for the vehicle with large tonnage, exhaust braking effect is limited, and has a certain degree of damage to the engine, installation of hydraulic retarder can avoid such damage, and achieve good and stable braking effect at the same time.

· Hydraulic retarder can only be used on long slopes?

Many owners believe that the hydraulic retarder is used in the long slope, and they do not often walk the mountain road.

In fact, this idea is with some limitations, hydraulic retarder is not only on the mountain road can play a role in the use of the effect, such as toll stations, traffic lights, traffic jams can be predicted in advance of the non-emergency braking situation, can use the maximum brake brake brake hydraulic retarder, gearbox selection of appropriate gear with retarder for vehicle deceleration, in place of braking. If it is only used on mountain roads, the hydraulic retarder is only used for half its value.

· How much does it cost to install hydraulic retarder on semi-trailer?

On the hydraulic retarder, the price is an inalienable topic. At present, on the market, the installation of hydraulic retarder, according to the model and the selected brand, the price is about 18,000-30,000, if it is imported hydraulic retarder, the price is even higher.

For many owners, the price is an important reason to prevent the installation of hydraulic retarder, after all, in the current low freight market environment, tens of thousands of dollars is not a small number, especially with the owner of the current application of more widely compared with the water device, the difference in price is really quite large.

However, this is just from the point of view, although the purchase and installation price of hydraulic retarder is indeed relatively high, the follow-up operation benefits are also very considerable. Don't believe me? Let's break it down:

· What are the advantages of hydraulic retarder?

1, lighter weight, more loading: hydraulic retarder small volume, light weight, has very important significance for the weight reduction of vehicles, especially compared with the current many owners use water device, hydraulic retarder in the weight advantage is more obvious, almost can reduce the weight of 1t-1.5t or so, can let the owner load more goods.

2, smooth braking: hydraulic retarder braking torque is large, the kinetic energy of the vehicle in the braking process into heat energy, keep the vehicle speed stable, stable braking without impact.

3. Cold braking is safer: Up to 90% of the braking of the hydraulic retarder can be carried out through the non-wear state in the process of vehicle running, so it can maximize the guarantee that the braking system is always kept in a cold state. In addition, the hydraulic retarder also has the function of constant speed control downhill, which greatly reduces the risk of braking failure caused by overheating of the brake in the long downhill. Reduce or avoid the problem of brake pad overheating or brake failure caused by continuous braking, improve driving safety.

4, prolong the service life of brake pads: according to the relevant experimental data, not suitable for liquid slow vehicle brake pad replacement cycle for mountain road conditions of 6 months, 12 months long-distance transportation; The vehicles using hydraulic retarder are 18 months and 48 months respectively, reducing the number of brake pad replacement, saving the cost of comprehensive vehicles.

5, reduce tire loss: installation of hydraulic retarder can reduce tire loss, greatly extend the service life of the tire, greatly reduce vehicle operating costs.

· How long will it take to pay back the cost after installing the hydraulic retarder?

According to the above analysis, the economic benefits achieved by using hydraulic retarder are mainly through extending the life of brake pads and tires, reducing the number of replacement of brake pads and tires, without water spraying device, without adding water, improve the actual operation efficiency, can save about 20,000 yuan a year on average, coupled with the reduction of vehicle weight, can make more transportation space under the condition of compliance, The cost of installing the hydraulic retarder can be offset basically in a year.

In addition, while profitability is important, safety is even more critical. Hydraulic retarder brings not only economic benefits to the owners, but also more reliable and stable braking effect. Especially with disc trailer axle and ABS/EBS system, the safety effect is better. DARO disc trailer axle is one of the representative products with high cost performance in the market. In the production process, the "one-piece" axle body replaces the traditional "three-piece" axle. The shaft head and shaft body are cast from a steel, eliminating the welding and connecting process of the shaft head and shaft body, which not only avoids welding deformation, but also increases the bearing performance of the shaft body. The axle has stronger bending, torsional and heavy load resistance. At the same time, in the product weight to achieve lightweight, compared with traditional products reduce about 15%, to help car owners to save energy and consumption, improve the comprehensive operating income.
