Evaluation: Hualing Hanma H9, the high horsepower under the diamond core

China's high-end heavy trucks have been extremely active in the past two years. Passenger car configuration and high horsepower have become the trend. “Hua Ling's persistence” has ushered in market opportunities. Not long ago, "Friends of Trucks" captured a Hualing Hanma H9 series 480 horsepower 6×4 tractor, witnessing the charm of Hualing's high-end heavy-duty truck under the core of the bare quality and diamond.

Hanma H9 driving indoor and outdoor

The Hualing Hanma H9 series 480 horsepower tractor adopts the Hanma H9 cab with European style and U-shaped front face design.

In terms of safety, the car has undergone a larger upgrade, with a cage skeleton structure and a high-strength steel plate skin structure, which meets the EU ECER29 anti-front, side impact, top pressure and front end drilling design requirements, which is commercially available in Europe. Uniform provisions in the field of vehicles.

\

\

The car is equipped with a split-type electric rearview mirror, which has a larger field of view than the integrated rearview mirror. When an accidental flaw occurs, if it is not very serious, the split type may only need to replace one mirror.

The integrated type must be completely replaced, and the cost is higher; similarly, the split type headlights also have the advantages in this respect, and the maintenance and disassembly area is small and more convenient.

\

\

Nowadays, the vehicle is pursuing light weight while pursuing high horsepower. The rim of the car is made of stone arch steel ring, which is about 3-4 kg lighter than the ordinary steel ring. It is more economical than the aluminum alloy steel ring. The aluminum alloy rim can also be replaced as needed.

\

\

The car's humanized features are also very obvious, especially in the design of the car ladder, the market is generally three-level, the smaller size of the user is relatively difficult to get on the car, and the star Kama designed four levels, providing more Great convenience.
In addition, the main and front passenger seats are air bag seats, and the common ones are the main driver airbag seats, while the front passengers are ordinary seats, which is also a concern for the driver's rest.

\

\

In the design of the interior of the cab, the functional area near the main driver is concentrated, which is convenient for overall control of the vehicle, and also saves a lot of space for the front passenger and makes the rest more comfortable.

\

Through measurement, the lower berth of the Hanma H9 cab is 70cm long and the width is moderate, which increases the adjustable space in front of the main and front passengers. The upper and lower berths are equipped with night reading lights, the position of the lights can be adjusted, the light is concentrated, and there is illumination. The role can also be read under the light.

Diamond core design highlights

"The next round of competition must be an endurance run. Now that the era of assembly vehicles has passed, the products must have core technology in exchange for the market." Liu Hanru, chairman of Hualing Xingma once said.

In the first half of the year, it achieved sales of 6,467 units. Hualing's diamond-powered Hanma engine achieved a 75% fitting rate, and achieved initial success in the promotion of core power.

Hualing Hanma H9 series 480 horsepower tractor is equipped with Hanma CM6D28 engine, which meets the national five emission standard, with a displacement of 11.8L and a maximum torque of 2250N•m. The low-speed and high-torque characteristics make it more fuel-efficient. protruding.
With less than 12L displacement, it is not easy to achieve such a large torque. The structure and overall reliability of the engine are very high. It is of great help from the world's top engine component supplier system.

\

It is also equipped with two diesel strainers to better filter the moisture and impurities in the diesel and protect the engine injectors.

\

In addition, the design of the water preheating switch can solve the problem of the cold winter in the north and the engine can not start normally. The main principle is to divide the fuel tank into two parts, one part is small, the high ignition diesel with low ignition point can be used, and the other part is generally used. For diesel fuel, use high-grade diesel oil before starting, and then use general diesel after starting preheating.

\

Both the gearbox and the rear axle are independently developed by Valin and have stable performance. The front axle adopts Hanma 6T drum front axle, and the drive axle is a single-stage deceleration bridge with a speed ratio of 3.42. By optimizing the design and using new materials, the axle torque is up to 40,000 N•m, and its own weight is lighter, with Hanma engine. Better match.

\

At the same time, it also adopts V-type thrust rod to ensure better stability of the vehicle; the disconnected balance bridge is rare in domestic heavy-duty trucks. Its main function is to reduce the weight of the body, and also has the disadvantage of not being overloaded. Transport use.

Dangerous car diamond power has more advantages

The Hanma H9 hazardous chemicals transport vehicle is positioned in the high-end hazardous chemicals transportation market with the goal of becoming an alternative to imported trucks. From the 480-horsepower model, it can be found that the safety is highly guaranteed and meets the requirements for transportation of hazardous chemicals.

\

\

\

In addition to the basic configuration of dangerous chemicals transportation such as exhaust pipe front and conductive support zone, Hanma H9 hazardous chemicals transport vehicle also uses aluminum alloy gearbox, aluminum alloy fuel tank, aluminum alloy gas storage cylinder, aluminum alloy steel ring, Lightweight leaf springs, high-strength frames, etc., under the premise of meeting the performance of the vehicle, the body weight is reasonably reduced.

\

In order to be safer, the Hanma H9 is also optimized on the electrical system. The CAN bus system is used to connect the sensors, controllers and actuators from the serial data line via the CAN bus. The main power switch is also designed inside the cab. The main power supply can be cut off at any time to protect the vehicle.

\

"Made in China" is moving toward "Creation in China". It is the general meeting of gold. It is the diamond that will shine. Hualing Xingma must continue to exert strength in the diamond power, and continue to plow in the details. I believe that one day The huge investment in independent research and development, and finally keep the cloud open to see the moon. (This article is from Star Horse)
