The collection trucks were unveiled at the Beijing Auto Show, bringing a strong shock to the heavy-duty truck industry, not only because of its support from industry giants such as CIMC, Chery Automobile, Yuchai Group, Fast Group and Fuhua Heavy Industry. Because it gave up the Steyr platform that domestic heavy trucks used for more than 20 years, it adopted the “Jieru UE platform†that is “independently developed and synchronized with the world’s mainstream heavy trucksâ€.
At the joint truck press conference held on April 23, Yin Tongyue, chairman of the joint heavy industry, said: "The goal of the joint truck is to compete in the global market, and it will demonstrate the power of Chinese creation on the international heavy truck stage."
The platform determines the technical level and level of the heavy truck. Can the UE platform support Jirui to enter the ranks of mainstream heavy trucks in the world?
What is the UE platform
Jirui UE platform is a brand new heavy truck platform built by Ruirui Union Heavy Industry, and it is also the first truly autonomous heavy truck platform in China. The letter "U" in the UE platform is the first letter of "United" in English and represents the joint truck. "E" is the characteristic of this platform, namely "Electronics", "Energy", and "Economy". (Economy), "Efficiency". The combination of two letters means: This is a smart, efficient technology platform.
Smart car cab
Adopting the CAN bus with advanced international level and highly integrated interactive information system, the joint truck realizes intelligence in satellite positioning, vehicle dynamic control, tire detection, in-vehicle network system and other aspects, and these intelligent information are all collected in A fully digital LCD dashboard. Unlike domestic traditional heavy-duty trucks, Jirui Union Trucks replaced the traditional pointer dashboard with the most advanced all-digital LCD panel. In the process of driving, the driver can see the car status information at a glance by only looking at the LCD screen behind the steering wheel. The application of this technology makes the speedometer, tachometer, water temperature gauge, fuel gauge, trip computer, tire pressure monitoring display, maintenance reminder system, fault self-diagnosis system, GPS positioning system, electronic map, audio-visual equipment display, etc. A display screen, and can be freely switched, so that the level of intelligent vehicles to a new height. Even in limousines, such configurations are extremely rare.
With the development of modern logistics, the demand for heavy trucks by users is not only to complete the cargo-carrying tasks, but also to increase the pursuit of comfort. The design of the joint truck cab reflects the application of advanced technology and humanistic care. The four-point full-float suspension cab drastically reduces the vibration of the cab, plus the air-cushioned leather seats and the steering wheel that can adjust the height and angle greatly, comfortably surpassing the mid- to high-class passenger cars. In the sleeper bed, there are also control buttons for interior lighting, audio and air conditioning, etc. All control buttons on the car are within easy reach of the driver.
Intelligentization makes the driver's operation more simple and easy. The comfortable driving environment reduces the driver's fatigue, makes the work a pleasant enjoyment, and improves the work efficiency of the personnel.
Powerful energy-saving engine
In today's international heavy truck market, more than 60% of products are fitted with engine power ranging from 400-450 hp. Engine displacements above 300 hp are basically concentrated in the 11L-15L range, of which the 12L diesel engine is internationally known as the “golden displacementâ€. However, domestic heavy truck engines are mainly concentrated in the 7L-10L. Jirui Union Truck Co., Ltd. is equipped with a joint power 6K series engine in line with international trends and domestic market demand. The power range of 10L and 12L displacement products covers from 300 horsepower to 520 horsepower, which injects a brand-new value concept for China heavy trucks.
In terms of energy saving and environmental protection, the joint power 6K engine also showed absolute advantages. The specific point-to-point fuel consumption of the Juri Union truck is 188g/kW.h, which is 16% lower than the world average of 225 g/kW.h. What is worth mentioning is that this is China's first mass-produced diesel engine that uses the national IV emission standard as a starting point and can meet Euro VI emission standards.
Large horsepower and low fuel consumption directly lead to higher transportation efficiency and lower costs. With the continuous increase of labor costs and oil prices, its advantages will become increasingly apparent.
Best shift timing transmission
As an important part of the vehicle powertrain system, the transmission directly determines the power output status and has the most direct influence on the vehicle's maneuverability. Ji Rui United truck transmission is provided by China's largest transmission manufacturer Fast. Fast sales of 700,000 units, its excellent reliability and transmission efficiency recognized by the industry. The latest developed AMT transmissions from Fast have the ability to shift gears at the optimal shift timing, providing greater flexibility and fuel economy. Among them, the Juri U Truck Tractor U460 is matched with an all-aluminum alloy AMT transmission. Compared with the traditional manual transmission, this product not only reduces its weight, but also improves transmission efficiency, smooth ride and fuel economy. , all have obvious advantages.
Highly efficient drive axle
As an important component of the transmission system, the performance of the axle relates to the transmission efficiency, reliability, and running noise of the vehicle. The maximum torque of the joint truck U460 can reach 2300N?m, which has the characteristics of quick start, quick acceleration, and strong climbing ability, which puts forward higher requirements for the technical level of the axle. The joint truck's drive axle was jointly developed by Union Heavy Industries and Fuhua Heavy Industry, the largest axle manufacturer in the country. The core members of the management and R&D team of Fuhua Heavy Industry are all from the famous American Meritor Axle Co., Ltd., and each person has more than 25 years of relevant experience. On the basis of making full use of international technological resources, Fuhua has independently developed a driving axle with advanced international standards in combination with domestic use. For example, under the same outer dimensions, through the more reasonable design, advanced analysis methods and manufacturing processes, the current domestic Fuhua 510 axle with the largest torque has been developed, allowing the joint truck to achieve greater torque capacity and Sex, to ensure the vehicle in a variety of conditions, reliable and efficient operation. As an important part of the UE platform, Fuhua Axle provides a high-performance drivetrain for the combined trucks of the international mainstream heavy trucks.
The Jurui UE platform that builds a smart car with a sedan-driven, energy-efficient and energy-saving engine, a gearbox with the best shift timing, and an efficient drive axle undoubtedly surpasses tradition in security, power, economy, and comfort. Heavy truck technology platform. With the advantages of CIMC in the field of special vehicles and the intelligent and efficient technical advantages of the UE platform, as well as the cost advantages of manufacturing in China, it should be said that the combined truck has the potential to enter the world's mainstream heavy truck market.
