I have always complained about the inconvenience caused by the lack of public propriety of the public, and use the words of Chongqing people to say that this is the way they leave their customers. Well, so we have enough time to try early. Maybe it was the first time to experience the 8×4 dump truck, a sense of freshness. It is no exaggeration to claim the status of Hercules as the tyrant's domineering appearance and sturdy power.
Dynamic performance
The test drive type is equipped with a high-pressure common-rail engine produced by Weichai, but the starting method is different from that of a normal truck. After turning the key, it is necessary to keep pressing the button at the lower right of the dashboard to start it. Since it is an empty car, the 2nd gear can be easily started, the throttle response is very rapid, and the speed hand immediately climbs to the economic speed region. There are not many vehicles in the suburbs of Chongqing. With the sound of the engine's strong, the speed has also been unknowingly accelerated to 80km/h. For Hongyan Special 8×4 Dump Truck, it is not easy to achieve such a speed in a short time.
Control and comfort
Special tyrants equipped with 9-speed Fuller manual transmission, the transmission shift control more convenient. Starting from 2nd gear to 4th gear, if the speed increases then you need to enter a higher gear. In addition, the Hercules sometimes has a small temperament. Due to the close combination of speed and stall, once the speed is not up to the required level, you don't want to cut into the top grade. When the speed is reduced or even a few taps the brake pedal and cuts into the low gear to run normally. In order to test the steering performance and turning radius of the car and to meet the photographer's shooting needs, the test team used to drive in a country lane that is less than 7m wide and can only accommodate two cars side by side, and turns the head in place. This not only tests the driving technology. , but also for the special tyrants out of the road problem, fortunately he completed the task very easily. Of course, this is also due to the use of ZF technology rotary valve power steering device, this type of steering device has a good follow-up, it can provide the appropriate power according to the steering force. When the steering wheel is relaxed, it basically automatically returns to keep straight.
Exterior and interior
The design of European commercial vehicles at the Hannover Motor Show was particularly shocked by the “tough physical fitness†of heavy trucks such as Renault, Scania, and Iveco. As a member of the Iveco family, special tyrants are somewhat similar to the Iveco Trakker heavy truck. Fortitude's front face reveals wild nature, such as the wild horses are ready to stand by at any time; the diversion holes on both sides take eyes and show off their large body to people. The Turbo's cab has a 3-speed pedal that provides easy access for drivers. The comfort of the seats in the car is good, and the interior dashboard of the cab uses an imitation peach wood interior with exquisite workmanship. In fact, the dump trucks used in the construction site do not need to display luxurious peach-like interiors. As a replacement model of the State III, the car is equipped with CAN bus fault automatic detection and driving status recording system, allowing the driver to understand the vehicle condition at any time. This is the highlight of the special tyrant.
Chassis performance
The special front and rear suspensions use multi-piece springs that are resistant to bumps. At high speeds, the members on the front and the driver's seats feel that the bumps are really small. In addition, the Steyr axle has a large carrying capacity, durability and reliability.
The special crossbar frame crossbeam adopts the corresponding structural design according to its load bearing condition at the frame assembly part, which not only guarantees the need of the girder load, but also minimizes the quality of the frame itself. Due to the complexity of the road conditions in China, the operating environment of heavy-duty trucks is usually relatively poor, which often results in unbalanced force distribution of the chassis frame. Therefore, the rear section of the longitudinal beam is designed to have a double-layered cross-section structure to alleviate this defect. At the same time, it also leaves room for modification of the vehicle, which can effectively avoid the damage to the frame structure during the conversion process and maximize the integrity of the frame and the original design bearing capacity.
Special fighter frame uses high-strength alloy steel, width is improved according to international common standards, hole accuracy is high, vehicle center of gravity height is reduced, stability is better, and optimal design conditions are provided for all kinds of special-purpose vehicles. The tyrant's chassis frame is a variable-segment side beam trapezoidal structure with a small gap between the main and auxiliary beams. According to the needs of the bearing, the vertical width of the frame is also designed to be narrow and wide at the front, so that the center of gravity of the engine and its attached assembly is reduced, the resonance amplitude and frequency are reduced, and the stability of the vehicle is greatly improved. Compared with the traditional through frame, it has been strengthened and improved in many aspects.
The dumping device of the car is very easy to operate. First, connect the transmission to the low gear, connect the power take-off switch on the center console, and then cut the manual valve on the left side of the driver's seat into the “lift†position and slowly raise the clutch and apply the appropriate throttle. Immediately, lift the car to complete the lift operation.
Service
Most heavy truck companies nowadays have the following levels of parts and spare parts management: central library, offices, 4S stores, qualified service stations, and accessories dealers authorized by the company.
In order to provide more convenient and quick supply of spare parts, Hongyan strives to improve the parts supply system, strongly supports the policy of distributors to store spare parts and participate in the service during the warranty period, and recruits qualified parts dealers throughout the country. At present, Hongyan has set up 12 central banks throughout the country, together with the perfect logistics and distribution system, which can meet the demand for parts supply.
In the case of dump trucks, it is essential to work in harsh environments. Special tyrants improve their work efficiency with their excellent dynamic performance and passability, and bring greater economic benefits to customers.
