In the new energy commercial vehicle track, Weidu Technology is the focus of the industry. A few days ago, the new energy intelligent heavy truck they created was officially released, with a maximum output of 1040kW (about 1414 horsepower), no-load 0-100km/h acceleration of 7.2s, and a full load range of 670km. And we found that the electric drive axle of this heavy truck beast is indeed not simple, which is the product of the cooperation between Hande Axle and Weidu Technology - dual-motor electric drive axle and single-motor electric drive axle, which open a door for the new track.
Strong power: the strongest combination exceeds 1400 horsepower
Entering the new energy track, the most intuitive subversion brought to the whole industry is "power performance" - compared with the internal combustion engine, the horsepower of the motor has become easy to obtain. AGIC provided a "2+2 electric drive axle" for the 6×4 pure electric heavy truck of Weidu Technology, that is, the latter two drive axles are dual-motor electric drive axles. Its maximum output torque of a single bridge is as high as 43,000N·m, and with the multi-mode control system developed by Weidu Technology, it can make the dual-axle 4 motors intelligently matched and coupled to achieve efficient driving.
For example, when starting with no load and driving at low speed, thanks to the large gear ratio of 63.85 + large torque in 1st gear, only a single motor can be used to meet the power demand. When it comes to high-load conditions such as climbing and overtaking at full load, the 4 motors can fully burst power, and more than 1400 horsepower can easily push the vehicle to run to 120km/h with full load, greatly improving the efficiency of trunk logistics.
In addition, Weidu Technology has also launched a 6×4 hydrogen fuel heavy truck, and the two drive axles behind it are a combination of dual motor + single motor. The peak total power of the vehicle can reach 780kW (about 1060 horsepower), and the power performance is also terrifying.
Long endurance: 670km under full load conditions
For new energy vehicles, efficiency, battery capacity and battery life are actually inseparable indicators. Hand's dual-motor electric drive axle applies low-friction multi-control control, high-level gear modification and full closed-loop control, and the transmission efficiency is increased by 4%-6%. The single-motor electric drive axle maximizes the efficiency of the electric drive system by optimizing the gear ratio in the high-efficiency zone, which is 3%-5% higher than that of the direct drive route.
The design of the electric drive axle itself is very efficient, and Weidu Technology has given it an intelligent control system, so that the efficiency of the whole vehicle has been greatly improved. It is worth mentioning that due to the high degree of integration of Hande electric drive axle, the vehicle architecture has obtained a lot of redundant space, so this pure electric heavy truck can accommodate 729kWh ternary lithium battery, which can achieve 670km ultra-long battery life under full load conditions, plus 800V high-voltage fast charging, which can fully meet the battery life needs of trunk logistics.
Lightweight: The advantages of the integrated e-axle are fully revealed
Nowadays, both car companies and leading suppliers regard electric drive axles as a major trend in the development of new energy tracks. Hand's dual-motor electric drive axle is highly integrated with the motor and control system, which greatly reduces the number of components, and is 150-200kg/light compared with similar integrated electric axles on the market. The weight of this reed technology pure electric heavy truck is controlled at 10.75 tons, which is due to the credit of Hande electric drive axle.
High reliability: long maintenance-free + high stability can be used with confidence
Modularity, high integration, and high reliability have always been the guiding lights for exploring the modern automotive industry. As the "leader" of the axle industry, AGIC has always been at the forefront of the development of the industry. As mentioned earlier, due to its high degree of integration, the integrated electric drive axle, like the electronic control system that should have been arranged in the body, has reduced a large number of cumbersome wiring harnesses, and also avoided the occurrence of "accidents" such as falling off and damage in harsh environments, which undoubtedly plays a positive role in improving the stability of the vehicle.
At the same time, Hande electric axles also support long-term maintenance-free. Not only is the first warranty free, but the main reduction provides 12/300,000 kilometers of oil change, and the wheel side is also maintenance-free for life, which greatly reduces the maintenance burden of cardholders in the later stage.
Write at the end
The cooperation between Hande Axle and Weidu Technology is a collision between "future" and "reality". A series of high-tech gives it a full sense of the future, whether it is a variety of "hard-core performance" or a variety of "high-energy technology", which makes the heavy truck market have a "sense of subversion". At the same time, the "reality" of the freight industry has always been inseparable from reducing costs and increasing efficiency. Through a series of "scientific means", Hande electric drive axle allows cardholders to make real profits: dual-motor electric drive axle can make a comprehensive profit of 2.3-34,000 yuan for users every year, and a single-motor electric drive axle can make a comprehensive profit of 1.9-28,000 yuan for users every year. Lightweight, efficient and reliable, the benchmark of new energy electric drive axle also depends on Hande!
