On the afternoon of May 14，It is controlled by Shaanxi Auto、Ningde Times、Shanghai rhinoceros weight、Hub power and other enterprises work together to tackle the key problems、The bottom electric traction heavy Truck jointly developed was officially launched in Datong City, Shanxi Province.。This model is being developed for coal logistics and transportation scenarios.，Carried with disk hub“Double power”Integrated electric drive bridge solution for motors，The technology has reached the international leading level.。
Member of the Standing Committee of Shanxi Provincial Party Committee、Lu Dongliang, Secretary of the CPC Datong Municipal Committee，Deputy Secretary of the CPC Datong Municipal Committee、Mayor Zhang Qiang，Li Ping, Vice Chairman of Ningde Times，Deputy General Manager of Shaanxi Automobile Holding Group、Wang Linlin, Chairman of Shaanxi Automobile Datong Company，Zhu Jiaming, Party Committee Member of Chinalco Capital，Zhu Zhengliang, General Manager of Times Qiji New Energy Technology Co., Ltd.，Han Jun, founder of hub power, and other leaders came to the scene.，Jointly witness the launch of new models。
It is understood that，Limited by chassis layout spaces，At present, a large number of new energy heavy Trucks are used on the market.“Back type”Battery arrangement，That is, place the battery pack behind the cab。But with the development of new energy Vehicle technology,，As well as the application practice of a large number of scenarios.，“Back type”The way the battery pack exists“Battery capacity is small、Occupation of cab space and view from rear window、The center of gravity of the Vehicle is high、Safety problems caused by accidental collision of Vehicles”And a series of disadvantages and disadvantages.。
Shanghai Rhinoceros Heavy Truck is used as the replacement heavy truck offline this time.、Integrated electric drive bridge system jointly developed by disc hub power，The whole structure is more compact.、Chassis space margin is larger，So that that battery pack can be arrange on the chassis，Not only is the center of gravity of the vehicle lower、The stability is better，And the security is also greatly improved.，With the help of pure electric chassis, no urea tank is needed.、Features of the fuel tank，It can also effectively and continuously improve the battery pack's endurance.；The whole vehicle is equipped with Ningde Times 513kWhBattery，Range over 350 km，The energy consumption of 100 km is 3% less than that of conventional trams％，Save 10% compared with natural gas model％Above。Calculated，Within 5 years of operation，A more conventional motor＋ANTThe Tractor earned more than 70000 yuan.，About 180000 yuan more than natural gas vehicles。
Under the witness of the leaders of all parties，The first batch of 200 bottom power exchange heavy trucks purchase agreements and 500 bottom power exchange heavy trucks strategic order agreements were signed at the ceremony site.。
And then，Lu Dongliang、Zhang Qiang and other leaders walked into the exhibition area.，Detailed understanding of the safety performance of the new off-line heavy truck、Technical indicators、Market application、Development prospects, etc.，He listened to the introduction of the current situation and development trend of heavy truck power exchange industry.，And visited the electric mining card with great interest.、The muck、Mixing and other engineering series vehicles and electric washing and sweeping、A series of sanitation vehicles and core components such as garbage removal and transportation。
General Manager Han Xiang Lu Dongliang、Zhang Qiang and other leaders introduced the application hub in detail.“Double power”Product features and technical advantages of integrated electric drive bridge of motor：
Compared with other electric drive bridge products on the market,，Disc hub“Double power”The integrated electric drive bridge driven by the motor adopts the axial flux drive motor developed by the full stack.，The volume and weight of the motor are reduced by about half.，Vehicle lightweight is better；
The structure is more compact，Compared with the traditional central drive axle, the size is reduced by at least one third.，Therefore, the chassis layout space is larger.，Not only can the bottom placement of the battery be realized，And can hold more.、Larger capacity battery pack；
Three-speed gearbox can be easily arranged，And each gear is a two-stage transmission.，In this way, the high efficiency range of the motor can be covered more widely.，The performance of energy consumption economy is also better.；
On this basis，Disc hub“Double power”Efficiency of the motorMAPUp to double 90，More efficient range，More feedback torque，Better effect of recovering energy for power generation，It is more conducive to energy saving, consumption reduction and mileage improvement.。
Lu Dongliang's technological innovation ability and disk hub power“Double power”The product performance and technical advantages of electric drive are highly recognized and appreciated.，And emphasize“Heavy truck power exchange is a new industry.，The market prospect is broad，There is a huge space for development”，It is hoped that all parties will continue to bring their talents into full play、Technology、Platform and other advantages，In product development、Technological innovation、Further deepen cooperation with Datong in marketing and other aspects，We will vigorously promote the accelerated development of Datong's new energy and high-end equipment manufacturing industries.，Speed up the cultivation of new quality productivity，Efforts will be made to build Datong into the first electric heavy truck model city with complete industrial ecology.，Realize in the new track、Take the lead in the new field。
