Retarder helps the downhill slope Unlike other vehicles, there are two additional pipe retarders on the left side of the engine that are used to deliver coolant to dissipate heat from the retarder. 80-90% of the braking task can be borne by the retarder. The service brake is always in a cold state. Only when the driver encounters an emergency, he only uses the service brake, no brakes, tires and other overheating concerns. Liberate the 12-speed gearbox. The top gear is the overdrive gear. The retarder is mounted on the gearbox sub-tank. Parallel Voith Retarder increases vehicle safety in the mountainous area. At the same time, it also reduces the number of brakes, prolongs the life of tires and brakes, reduces maintenance frequency, and reduces downtime. Non-long-term mountainous areas can remove the water tank (400 -1000kg), to improve the loading quality, while eliminating the need to add water (200-300 yuan per day in the southwest); the maintenance period is greatly extended, vehicle operating costs are reduced, and the retarder investment is withdrawn on average for one year. The net weight of the hydraulic retarder is about 48kg, which can be seen at the bottom. The piping design of the hydraulic retarder is very compact. Users talk about the use of liberating retarders Master Liu, a liberation pilot of the J6P pilot vehicle, said that during the visit of Jiefang retarder, Sichuan Jiajiang County went to Lijiang, Yunnan and Ruili, with a total distance of 2,000 kilometers. Before using the retarder, the average speed of the downhill is 50, and the average speed after use is 70. It will save 4 to 5 hours. Before using the retarder, change the brake shoe for at least 3 months, costing about 3,000 yuan each time; replacing the brake drum every year, costing 2000-3000 yuan; 400-500 yuan per month for water; wearing tires after use Greatly reduced, within a year, the cost of 28,000 retarders can be recovered. After the retarder is used, the watering device with a total weight of 1.5 tons can be eliminated, and a 600-liter fuel tank can be installed in the original tank position. Since almost no foot brakes are used throughout the entire journey, a single 2,000 km can save 100 liters of fuel. When matched with Voith retarder, the average speed is higher, shifts are fewer, wear is reduced and operating efficiency is higher. Liberation J6 pilot version brings users high-safety, high-efficiency, high-yield advantages to the user experience, making card safer driving safety more secure!

The terrain and road conditions in the southwestern region are complex because long downhill slopes cause brake overheating to fail, resulting in frequent accidents. At present, trucks in the mountainous areas generally use a watering device to cool the brake drum, which tends to cause slippery roads. In winter, the temperature is low, and it is easy for roads to freeze in high-altitude areas, causing great hidden dangers to traffic safety. Therefore, it is particularly important to use a hydraulic retarder instead of a watering device. Liberation J6 pilot version coupled with Voith retarder to protect the safe transport of card friends!
