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

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

·Hydraulic retarder can only be used when going down a long slope?

Many car owners believe that the hydraulic retarder is used when going down a long slope. They don't need to install it if they don't often take mountain roads.

In fact, this idea has some limitations. The hydraulic retarder can not only be used on mountain roads, such as toll stations, traffic lights, traffic jams and other non emergency braking situations that can be predicted in advance, the maximum braking gear of the hydraulic retarder can be used for deceleration braking, and the gearbox selects the appropriate gear to cooperate with the retarder for vehicle deceleration, Instead of stepping on the brake. If it is only used on mountain roads, the value of hydraulic retarder is only half utilized.

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

The price of hydraulic retarder is an inseparable topic. At present, the price of installing hydraulic retarder in the market is about 18000-30000 according to the model and the selected brand. If it is an imported hydraulic retarder, the price is even higher.

For many car owners, the price is an important reason to prevent them from installing the hydraulic retarder. After all, in the current market environment of low freight, tens of thousands of yuan is not a small amount, especially compared with the shower currently widely used by car owners, the price difference is really large.

However, this is only from the immediate point of view. Although the purchase and installation price of hydraulic retarder is indeed relatively high, its subsequent operation benefits are also very considerable. Don't believe it? Let's analyze in detail:

·What are the advantages of hydraulic retarder?

1. Lighter self weight and more loading: the hydraulic retarder has small volume and light weight, which is of great significance for vehicle weight reduction. Especially compared with the water spraying device used by many car owners at present, the hydraulic retarder has obvious advantages in self weight, which can reduce the weight by almost 1t-1.5t, which can enable car owners to load more goods.

2. Stable braking: the hydraulic retarder has large braking torque, and the kinetic energy of the vehicle is converted into heat energy during braking, so as to maintain the stability of vehicle speed and smooth braking without impact.

3. Safer cold braking: up to 90% of the braking of the hydraulic retarder can be carried out through the wear-free state during the driving of the vehicle, so the braking system can be kept in the cold state to the greatest extent. In addition, the hydraulic retarder also has the function of constant speed control on downhill, which greatly reduces the risk of braking failure caused by brake overheating during long downhill, Reduce or avoid the problem of brake pad overheating or brake failure caused by continuous braking, and improve driving safety.

4. Extend the service life of brake pads: according to relevant experimental data, the replacement cycle of brake pads for vehicles not suitable for liquid buffer is 6 months for mountainous road conditions and 12 months for long-distance transportation; For vehicles using hydraulic retarder, it takes 18 months and 48 months respectively to reduce the number of brake pad replacement and save the cost of comprehensive vehicles.

5. Reduce tire loss: after the hydraulic retarder is installed, the tire loss can be reduced, the service life of the tire can be greatly prolonged, and the vehicle operation cost can be greatly reduced.

·How long can the hydraulic retarder be installed back?

According to the above analysis, the economic benefits realized by using hydraulic retarder are mainly through prolonging the service life of brake pads and tires, reducing the replacement times of brake pads and tires, eliminating the need for watering device and adding water, and improving the actual operation efficiency. On average, about 20000 yuan can be saved a year. In addition, the reduction of vehicle weight can free up more transportation space under the condition of compliance, Basically, the cost of installing the hydraulic retarder can be offset in one year.

In addition, while profitability is important, safety is more critical. Hydraulic retarder not only brings economic benefits to car owners, but also its more reliable and stable braking effect. Especially when used with disc axle and ABS / EBS system, the safety effect is better. Darong disc axle is one of the representative products with high cost performance in the current market. In the manufacturing process, the "one-piece" axle body is used to replace the traditional "three-piece" axle. The axle head and axle body are cast from one steel, eliminating the welding connection process between the axle head and axle body, which not only avoids welding deformation, but also increases the bearing performance of the axle body, The axle has stronger bending, torsion and heavy load resistance. At the same time, the weight of the product is reduced by about 15% compared with traditional products, which helps car owners save energy and reduce consumption and improve comprehensive operating income.
