Truck Electric Drive Axle

Railway freight car bogies, also known as railway freight car running gear, are key components of railway freight cars. They play an important role in bearing the load from the car body and the track, guiding the vehicle along the rails, and alleviating the force of movement.

From August 28 to 31, 2025, the highly anticipated PRO//Motion Expo 2025 (Russian International Railway and Motion Exhibition) grandly opened at the Russian Railway Museum in St. Petersburg. PRO//Motion Expo is currently the largest railway and transportation exhibition in Russia and the Commonwealth of Independent States (CIS), attracting extensive participation from railway companies from CIS countries and around the world. Over the four-day exhibition, exhibitors showcased cutting-edge technologies and innovative achievements in the railway transportation industry.

The highly anticipated Middle East Saudi International Railway and National Road Transportation Exhibition (SAUDI RAIL) will be grandly opened in Riyadh, the capital of Saudi Arabia, from October 19 to 20, 2025. As an annual event in the field of rail transportation in the region, this exhibition focuses on Saudi Arabia's grand blueprint for rebuilding the future new city. With its strong industry influence and extensive market radiation, it has attracted many industry elites and enterprises to participate actively. The market heat continues to rise, showing a booming development trend.

The motor-drive adaptation process refers to the process of matching the motor with the electric drive system. In actual applications, the motor and the electric drive may have different characteristics, such as voltage, power, speed range, etc. Therefore, in order to achieve optimal performance, efficiency and stability, they need to be properly matched and configured.The adaptation process usually includes the following steps: Specification analysis Evaluate the technical specifications of the motor and the electric drive, including rated power, rated voltage, rated speed, maximum torque, etc.;

When judging the power performance of a vehicle, the first thing to look at is the engine, gearbox and axle, which are often called the "three major parts". It is these three parts that together make up the power chain of the truck. To solve the problem of axles, you must first understand what axles are. The explanation given by Baidu Encyclopedia is: "Axles are also called axles. They are connected to the frame through suspension, and wheels are installed at both ends. They are mainly used to bear the load of the car and maintain the normal driving of the car on the road."

As an international event in the logistics and transportation industry, the exhibition attracted more than 1,650 companies from 41 countries and regions, and major global manufacturers exhibited their latest research results and design concepts. Among them, Qingte Group, as China's largest independent axle manufacturer, brought a new generation of electric drive axles, traditional axles, trailer axles and a full range of castings to Hannover, fully demonstrating the comprehensive competitiveness of power system solutions in traditional and new energy fields and large castings business products.

With the rapid development of low-altitude economic technology, the requirements for battery performance of drones and low-altitude aircraft are becoming increasingly refined. In terms of application scenarios, EVE Energy continues to deploy low-altitude economic tracks, and has launched a comprehensive solution for low-altitude economic batteries that combines high safety, high specific energy, long life, long endurance, ultra-fast charging, and high power to meet the differentiated needs of agricultural plant protection drones, consumer drones, industrial drones, manned eVTOL and other scenarios.

As the layout of automobile parts gradually changes from decentralized to centralized, electric drive axles improve efficiency and reduce energy consumption by simplifying the structure, becoming the dominant direction of pure electric truck development. Due to its unique structure, electric drive axles do not require a gearbox when driving pure electric vehicles, thereby reducing the loss in the process of kinetic energy transmission. Therefore, the industry generally predicts that the combination of motors and electric drive axles and distributed electric drive technology will become the dominant development direction of pure electric trucks in the future.

Be the "load bearer" of safe travel Walking into Qingte Industrial Park, the eight characters "Chinese Axles, Made in Qingte" come into view. The axle is also called the axle. If the engine is compared to the heart of the car, then the axle is the two legs of the car. It is connected to the frame through the suspension, and all the loads are borne by the axle. The steering axle installed on the front wheels of the car plays the role of driving the car to turn; the drive axle installed on the rear wheels of the car drives the car forward.
