In the era of electric drive, the domain is moving towards the future

From light-duty electric drive bridges to medium-sized electric drive bridges, and then to hybrid power systems, Jiefang Power is actively laying out electric drive assemblies in the key field of powertrain, striving to transition to new energy, and completing the construction of new energy manufacturing technology system and production line layout.

Jiefang Power Light Electric Drive Bridge is the latest new energy vehicle bridge launched, mainly targeting the light urban logistics market. It can meet the needs of fully loaded 6.5-8.5 ton pure electric, fuel cell, and extended range hybrid light vehicles, with advanced configuration, safety and reliability, high efficiency and energy saving, and flexible matching.

Jiefang Power's medium-sized electric drive bridge is suitable for various application scenarios such as medium-sized sanitation, logistics, heavy-duty 6 * 4 traction, 10.5-meter public transportation, suspension structures, etc. The rated axle load is 13000kg, the peak output torque is 31000N · m, and the motor power density reaches 4kw/kg. By adopting technologies such as centralized integrated dual motor parallel configuration, multi-stage deceleration, and high-power density flat wire motor, the optimal comprehensive performance is achieved, making it an ideal matching for the entire vehicle.

China has proposed the policy of "peak carbon emissions and carbon neutrality", with a focus on strengthening the clean energy industry, striving to leverage market advantages and domestic demand potential, and continuously optimizing the development layout of the renewable energy industry. For the commercial vehicle industry, optimizing traditional energy product technology and developing new energy products are important guarantees for promoting green and low-carbon development and achieving carbon neutrality in the automotive industry as scheduled.

The hybrid system exhibited by Jiefang Power this time is the P2 configuration hybrid powertrain with the widest application range of new energy vehicles at present, which can be understood as engine+electromechanical coupling+drive motor+gearbox. The principle is to have two sets of drive systems, including an internal combustion engine system and an electric motor drive system. The two systems can work in coordination simultaneously or drive the vehicle separately. Its advantage lies in achieving good power and economic improvement with minimal renovation cost. In short, a separate drive motor is installed between the engine and gearbox of traditional car models, allowing these two sets of power to be output through the gearbox.

In the internal combustion engine section, this hybrid system is equipped with the Liberation Power 4DT2-18E68 engine, with a displacement of 2.44 liters. In addition to having strong foundation design in terms of fuel economy and reliability, this engine also optimizes the commonly used speed and torque range of the engine for this hybrid system, ensuring that the engine is more in the fuel economy zone while maintaining the overall power performance of the vehicle, thus ensuring both power and fuel efficiency.

In the drive motor section, the hybrid system is equipped with a permanent magnet synchronous motor, with a maximum output power of 65 kW, 88 horsepower, and a maximum output torque of 370 N · m. Of course, in order to achieve better power distribution, the HCU control system installed in the original vehicle can intelligently distribute torque in different scenarios. In order to further achieve power transmission, a 6-speed ATM gearbox specially developed for new energy vehicle models is connected to the rear of these two power systems, which further achieves overall power connection and transmission through the gearbox. Similarly, during the deceleration of hybrid light trucks, the motor can further recover kinetic energy. Through further coordination of the hybrid system, it can enable the diesel engine and drive motor of the entire vehicle to operate better in the "high-efficiency and low consumption" working range, thereby achieving better fuel economy. The HCU and control strategy independently developed for the hybrid system can further support the optimal design goal of the hybrid powertrain at the software level, thereby achieving better fuel economy. The tested regulatory standard cycle fuel saving rate exceeds 15%, and the mountainous intercity logistics fuel saving rate reaches over 28%.
