Actually there are drivers who do not know the existence of hydraulic retarders? Every minute to give you a science

Recently, Xiao Bian was surprised during the interview and found that there are still some truck drivers who do not know the existence of “hydraulic devices” that ensure the safety of transportation. After hearing such news, Xiao Bian really has a little bit of this. Some truck drivers are in a hurry. After all, everyone eats on trucks. They should be aware of the additional devices on the vehicle. Even if they have not used it personally, they should be aware of it.

After Xiao Bian calmly thought about it, he believes that this part of the truck driver should belong to the users of the green line in the plain area. The road conditions experienced during the daily transportation are relatively gentle, so the vehicle will not install a hydraulic retarder. Even so, Xiao Bian decided to do a simple popular science for this part of the driver to let them know how the hydraulic retarder conquered the long downhill slope.

The hydraulic retarder, commonly known as “Liquid” in the circle, is a piece of hardware that is installed at the rear of the gearbox. The vehicle will only work when it enters the downhill section. Its working principle is to convert the kinetic energy of the downhill slope through the oil in the hydraulic retarder to provide thermal energy. The oil then re-enters the vehicle's cooling system to dissipate heat energy to the outside world. In simple terms, it means that the vehicle speed is reduced by the hydraulic device and consists of a retarder body, an operating device, and an electronic control unit.

The biggest advantage of this “artifact” is that it can significantly reduce the use of brakes during long descents, greatly improving driving safety, and at the same time, it can relieve drivers’ nervous emotions and driving fatigue, and respond calmly when going downhill.

Taking the ZF Intarder hydraulic retarder as an example, the Intarder braking torque is transmitted through the speed increasing gear to the output shaft of the transmission. The braking torque is up to 4,000 Nm. The braking action can be as high as 90%, allowing the vehicle to achieve braking. The higher common vehicle speed can control the vehicle's constant speed downhill, reduce frequent driving brakes, and no longer need to worry about brake overheating or failure.

In addition, Intarder fluid can choose the braking gear to provide different braking force, minimize brake wear and increase tire life by more than 3 times. For every 1 million kilometers traveled, the Intarder hydraulic retarder can reduce 25 kilograms. Brake dust, reduce air pollution.

Not only that, Intarder's hydraulic retarder offers another advantage. Xiao Bian learned that it is integrated in the ZF transmission and does not require additional space. The structure is more compact, and it can be easily connected to manual and automatic transmission systems. It is perfectly integrated into the vehicle braking system. Including speed control. This is also very helpful for the lightweight design of the vehicle, which can help the vehicle to achieve higher loads, and the integrated retarder does not have any restrictions on the power takeoff combination, and is also very competitive in the heavy truck market.

In order to be considered by the drivers who have already moved, Xiao Bian has also explored for the friends who do not understand the hydraulic retarder. According to the different installation methods, the hydraulic retarder can be divided into two types: tandem type and parallel type. The tandem installation can be installed between the transmission shaft and the gearbox, occupying a certain amount of axial space, and the installation requires a simple adjustment of the length of the transmission shaft. The parallel type is an integral part of the transmission and transmits power through gears. It does not require excessive space adjustment during installation.

How? When you see here, the driver who has not understood the retarder before, especially the friend who has experienced long downhill is not sorry, missed such an "artifact". However, it is not too late to know it now. If your vehicle often experiences long downhill sections, you may wish to add a liquid slowdown and enjoy the process of safely downhill after it.
