Card Friends necessary artifact exclusive analysis of hydraulic retarder
When using a retarder, will the engine speed increase beyond the economical speed zone, will it increase fuel consumption?
In the braking process using the retarder, the driver does not need to step on the throttle, the injector will not be injected, and therefore it will not consume fuel, so even if the engine speed is increased, it will not consume fuel.
FAW Liberation Hydraulic Retarder
Which is better with hydraulic retarder and engine brake?
Both hydraulic retarder and engine brake can improve the braking safety performance of the vehicle. However, we can clearly see from the following figure that the average braking power of the retarder is much greater than that of the engine brake, especially for a better braking effect (deceleration) at higher vehicle speeds. .
In addition, the hydraulic retarder also has a downhill constant speed function not provided by the engine brake, which can greatly improve driving safety and comfort.
Is a hydraulic retarder suitable only for downhill slopes?
Hydraulic retarder is only suitable for downhill is a misunderstanding. When the vehicle approaches a certain roundabout, a traffic light, or a station, the retarder is activated at any time when the direction is changed or the speed needs to be reduced, regardless of whether it is necessary to stop the vehicle completely afterwards. For experienced drivers, the retarder can replace the service brake in 90% of cases.
Why is it that the retarder that is equipped to liberate is a wear-free auxiliary brake?
The liberation retarder is synonymous with wear-free auxiliary brakes globally because the components in the retarder are not in direct contact with mechanical friction during the operation of the retarder. Realize vehicle retardation.
What is the actual effect of using a hydraulic retarder?
In August 2012, FAW Liberation conducted a real vehicle test with a retarder on the Iasi highway. The entire section of the experiment is a 51-kilometer downhill road, with a height difference of 1515 meters, a maximum longitudinal gradient of 4%, and an average longitudinal gradient of 3%. It is the longest freeway in the country's continuous slope segment so far.
Experiments have shown that a liberation truck equipped with a hydraulic retarder can use a heavy truck with a total haul weight of 55 tons without the use of a service brake, and smoothly pass the first longest domestic train at a speed of about 60 kilometers per hour. Downhill, completely solved the problem of long-heavy slopes under heavy trucks.
Flat disk Rotary Damper mainly used for large diameter, small height space. Disk dampers provide energy absorption and rotational deceleration. We offer many different models from mild to extreme. Our disk dampers are the perfect solution for a wide range of applications, from scanner, and glove boxes to auditorium seating to. Disk dampers are designed to control and smooth out the opening and closing of lids, and doors.
Our damper is conducive to performing structural movement in soft, silent and safe environment, mitigating impact load, avoiding strike damage, prolonging mechanical life, reducing noise disturbance, improving product quality and improve customer satisfaction.
