The positioning of HOWO-A7 series products is oriented towards the international market and domestic high-end heavy truck market. During the design and development process, in order to ensure the success in global competition, Sinotruk cooperated with international first-rate suppliers on important components to design, and in accordance with the international key assembly design standards, combined with the actual characteristics of China, combined with scientific research and development, and a special package, a New international technology cooperation. The HOWO-A7 series adopts German ZF steering gear and oil pump, WABCO double cylinder air compressor, full-vehicle brake valve, and jointly designed AMT transmission and SartShift intelligent tiptronic gear shifting system, German VOSS brake interface, MANN -HUMMEL fuel filter and plastic air filter system, SABO shock absorber, BEHR cooling system, VDO instrument + control system, VDO sound system, WESTFALIA exhaust bellows, HENDRICKSON rubber suspension and other world-class technologies and products, combined with China Heavy Duty Truck has many years of heavy truck experience and understanding of market precision, and has developed many excellent assemblies with China National Heavy Duty Truck's independent intellectual property rights.
Powerful heavy truck heart - China's most fuel-efficient engine
The newly designed Sinotruk D12 series engine is currently the most representative heavy-duty engine in China, with a power range of 340-460Ps.
China National Heavy Duty Truck Co., Ltd. has developed a series of new technologies and achieved significant differences in results, making the D12 engine a good manoeuvrability. The large displacement and high power make the vehicle gain power from low idle speed. At the same time, its wide speed range makes the whole machine get constant power value and maximum torque value. This characteristic determines the perfect fuel economy and driving performance of the D12 engine.
Exquisite manufacturing and assembly processes make the engine overhaul miles above 1 million kilometers. Effectively solve the problem of high after-sales failure in other domestic similar models.
To meet the needs of different customers, CNHTC also tailored the D10 series engine (270PS-380PS) for the HOWO-A7. The D10 series engine adopts the domestic first technology of independent innovation—supercharger center. The application of this technology has resulted in substantial changes in the intake and exhaust systems. The intake air is smooth and the exhaust is simple. This makes the vehicle's “lung†function more prominent and the fuel economy even better.
Both D10 and D12 engines meet the national 3 emission standards and possess the technical potential of the 4 and 5 countries.
Create the leading technology for the new era of heavy-duty truck transmission in China
—— SMARTSHIFT-AMT Intelligent Shift Autotronic Transmission
SMARTSHIFT literally translates as "smart shift." AMT is the standard technology for the world's high-end heavy trucks. 50% of European trucks use AMT gearboxes. With the launch of China National Heavy Duty Truck SMARTSHIFT-AMT, Chinese users can also enjoy the comfort of international high-end heavy trucks, thus upgrading China's heavy truck technology to the ranks of the world's advanced heavy trucks! Leading China (Asia) heavy trucks into the era of automatic shifting.
China Heavy Duty Truck SMARTSHIFT transmission is a 16-speed electronically controlled, automatic transmission, like a highly skilled driver driving a truck, with a higher fuel utilization.
The working principle and structure of AMT is completely different from the AT of a car. The AT of a passenger car is a mode that drives the hydraulic oil through the turbine, and the hydraulic oil drives the mechanical device. The efficiency of the oil drive is more depleting. Therefore, 100 kilometers generally consume 1-2 liters more fuel than the manual box. AMT is a mechanical gearbox that achieves automatic shifting through electronic control. When shifting gears, it is also like a manual box. To disengage the clutch, the engine is upshifted or the transmission is braked. When the meshing synchronization is achieved, the most suitable gear is automatically switched. Manual box fuel saving 3% -5%.
Suitable for a variety of conditions. With the use of Sinotruk's SMARTSHIFT, drivers can focus more on driving and the surrounding traffic conditions and respond in a timely manner. Help new drivers reach the level of advanced drivers. The driver can still manually shift gears. Switch to manual mode and use the joystick to select the appropriate gear. Trucks using SMARTSHIFT do not have a clutch pedal and shifts are fully automatic.
Extremely high reliability. All AMT hardware has been used and matured for many years in the European heavy truck industry.
Technical and technical front and rear axle assembly
The new front axle (front axle), which is optimized using finite element and related engineering software, is divided into two categories: 7 tons and 9 tons:
