Recently, a publication introduced in the CCTV military column for the PLA Second Artillery Force (now changed to Rocket Forces) manufacturing, new energy technology-driven wheel axle heavy duty 6 with video and mobility by nature. Subsequently, the Chinese social networking site, more military “Big V” on this vehicle were introduced video graphics reproduced and sparked heated debate.
New Energy Intelligence Analysis Network as early as 2006, began military of prospective new energy technologies, applied roadmap for follow-up reports. In 2014, China will be the core technology of new energy, vehicle manufacturing and development of the whole industry chain as an important and strong implementation of the “direction.” By 2020, China has become the world’s largest new energy vehicle market to maintain the world’s most promising new energy incremental market, and has the world’s most complete industrial chain of new energy markets.
In the new civilian energy, charging facilities and includes a drive motor, battery and control strategy of supporting business involved, the Chinese have an absolute right to formulate policy on a global scale and cost of ownership. This has resulted in, whether civilian depot, commercial vehicle factory and purely military equipment manufacturing groups, have enjoyed direct bring new energy industry policy and core technologies absolute bonus!
Note that:

2. This article will discuss the central video presentation using new energy technology driven, less than 2 6 bridge heavy vehicles, combined with close-up of static social media release, technical and tactical comprehensive judgments. Due to objective factors, expressed full information point and the actual state of the art, there will be a great difference.
1, HTF5700HEV heavy wheeled vehicle adapted extended-hybrid drive technology:
HTF5700HEV wheeled appear in the video heavy vehicles, vehicle number is easy to see from the “HEV” represents hybrid technology. From the Chinese market than to new energy models in a variety of driving modes sale, HEV stands for hybrid technology unplugged, similar to the Toyota Prius made.
However, a comprehensive alignment, suspension CASC (China Aerospace) HTF5700HEV heavy wheeled vehicle identification using extended-mixed gasoline-electric drive technology. An extended-range hybrid drive technology in China car market applications, there are also segments do not have the plug-in function and have the plug-in function. As HTF5700HEV heavy wheeled vehicles, whether to include a plug-in function, I prefer not to have the plug-in function.

However, the sub-frame may be fixed on the motor and the motor controller are not moving parts, you can easily reach levels of IP67 or IP68. Can be lower cost, requires lower sealing cooling liquid cooling the motor, the hydraulic oil may also be used for cooling the motor and reducer integrated solution.
2 set by the modular drive axle wheel motor configuration, a smaller motor power and torque, the drive axle completely abandoned and other mechanical parts. However, the wheelMotor and a reducer are of moving parts, fixed to the motor controller and the sub-frame, through the associated high voltage cable 2, or 3 groups groups; wheel motors also require cooling coolant or hydraulic oil through the set of tubes 2 associate. Sealing, and cooling of the motor power transmission, we must rely on a cable to allow the correlation for the range of motion. Most importantly, tire size restricted Effect wheel space, the overall size of the wheel motor is strictly defined, the ratio of the maximum power and torque output of the unsprung mass, are very difficult to control.
See generally, between the modular drive axle shaft of the motor group consisting of 1, regardless of cost, reliability or unsprung mass, to be better than the modular drive wheel axle set by the motor 2 configuration.

It is noted that, HTF5700HEV heavy wheeled vehicle bridge and an 8 second PLA artillery equipment, heavy-duty axle 12 axle rear wheel carrier 10 multi as steering drive technology, in order to reduce the turning radius and axle reduce tire wear. This is a multi-wheel axle drive shaft between the carrier most commonly used technique.
If a wheel motor drive technology employed, then HTF5700HEV heavy wheeled vehicle, can be set to all-wheel steering and drive capability, i.e., the left and all group 6 wheel motor is transferred, the right wheel motor reversal group 6, a “zero” in situ radius turn. By independent drive axle is installed the entire tie rod assembly, obtained Shaanqi SX2550 type heavy vehicle wheel axle 10 has the same all-wheel steering capabilities.
Integrated HTF5700HEV heavy wheeled vehicle development, testing and setting time of the node and tactical applications, high-power, the possibility of the modular drive axle for cooling and sealing requirements between a lower shaft of a motor configuration very high.

4, HTF5700HEV heavy wheeled vehicle is driven 12X12:
CCTV video, show HTF5700HEV heavy wheeled vehicle forward, lateral, backward multidimensional driving attitude and drive axle close-up. Careful study and determination, HTF5700HEV heavy wheeled vehicle includes a static theme change 12X12type.

amplified clearly visible, the drive wheel hub by 3,4,5,6 bridge “convex” wheel-side reducer, but 3,4 function does not have a steering drive axle, steering drive axle 5,6 and 1,2 can turn the steering drive axle and synergistic capabilities with full interchangeable steering system.
Photo Shaanqi SX2XXX heavy wheeled vehicle first X drive axle steering wheels inside of the hub, set down by the drive axle modular, standard A-type arm, the pull rod assembly and a hydraulic steering damper system.
To be sure, HTF5700HEV heavy wheeled vehicle is driven 12X12, inter entire drive axle shaft drive motor, drive axle, the upper and lower A-type arm, the ability to have interchangeable. The crucial swing arm and steering and other key systems with modular interchangeability is not designed to take the initiative to depots, but the military standard mandatory.
5, HTF5700HEV heavy wheeled vehicle new extended-oil hybrid electric technology brings tactical capabilities:
The extended-wheeled hybrid HTF5700HEV art heavy-duty drive with, powered by a diesel engine to the generator, and the generator is converted into electric power through, assigned to the motor shaft between the modular drive axle, a plurality of drive motor can be carried out by state 12X1-12X12 drive axle.
Of course, the author can not be determined that, HTF5700HEV heavy wheeled vehicle whether to use a set of high-power diesel engines are arranged at the cockpit is located, or the group 2 located in the power of the diesel engine are arranged on both sides of the frame .
Whether a group is set using the power diesel engine, or the group 2 laterally arranged power diesel engines, will increase a group transmission (governor) before the generator , to respond to different loads and different climatic conditions and different speed, impact on the efficiency of the power output.
+ Good low load climate, economic diesel engine rotational speed (1400 rpm -2200 rpm), a transmission (speed governor) is a small gear ratio, or 12X6 to 12X8 in the driving mode, the motor needs to complete tactical vehicle.
In a high load maneuver requirements + cold climate, economic diesel engine rotational speed, a transmission (speed governor) is a large gear ratio, the driving mode to the 12X12, complete tactical battlefield state of the vehicle.
I almost determined, HTF5700HEV heavy wheeled vehicle 1 set of (plurality of sets of) a storage battery system composed of lithium iron phosphate-based. Given the convenience, security dominated in 2020, continue to reduce costs (400 yuan / kWh) lithium iron phosphate batteries and BMS system is fully provided by Chinese battery supplier, HTF5700HEV heavy wheeled vehicle even with the all-electric drive (diesel engine stops running), low noise and low radiation covert tactical mobility.
Because HTF5700HEV wheeled heavy duty vehicles, as DF series of strategic missile carrier with the use and transfer, should not appear in the front line of combat possible. Thus, an adaptation kit modest charge carrier, can cope with a shorter distance all-electric drive, primarily coat the carrier stably and continuously provides 220V / 380V or higher voltage output capability, the hybrid drive technology is the extended-militarized another tactical advantage.
to solve the multi-bridge power drive capability synergy, which rely on mechanical technology and for the axle and multi-axle drive electronics technology is relatively backward Chinese automobile industry, it is a mind “true TM” fragrant tonic. Modular electric high-voltage cable linked with the drive axle, transfer completely removed, a plurality of sets of front and rear drive shafts, reducing the weight, simplifying the structure. The only balance of power battery is loaded power to bring the cost of upgrading power battery thermal management and control integrity strategy.
However, as for carrying Chinese national security, to ensure that “wind Express” global quality of service will be up to heavy wheeled vehicles, because fluctuations in the cost of new energy technology brings, and new energy technologies with applications to reliability and significantly improved tactical advantage, it is not worth mentioning.
I have something to say:
by the CASC (China Aerospace) system under the manufacturing companies, the official use of extended-range hybrid drive HTF5700HEV heavy wheeled vehicle’s debut, heralding a new energy technology or military equipment of the People’s Liberation entered a substantive test installation phase. This is also confirmed from the side, China’s new energy vehicle technology and applications continue to commercialize the same time, the development of military Guairu a substantial node.
In October 2012, he wrote “span six – Western military” new energy “vehicle technology” article, aims to introduce the German and Japanese military technology in new energy technologies in the state of development in which the nature of the test, carried out a more detailed description. Since this time, the European “BBA” and Japan were “two fields”, the traditional power and axle technology has a strong voice and market dominance. Military of new energy technologies or to fit the traditional power of HEV technology-based.
in September 2015, the author wrote, “” US military testing hybrid military vehicles “On the military new energy technologies,” a text, designed to introduce the US tend to use diesel technology with PHEV It has a large power reserve, large load capacity of the battery HEV technology for low intensity non-militarized new energy technology called the real test of the environment, in Afghanistan and Iraq and other countries.
March 29, 2017, he wrote “Song Nan: talk about Japanese Army and Navy military of new energy technologies,” a text, aims to introduce the Toyota, Mitsubishi and Komatsu et wheel shoe equipment suppliers, Panasonic, Toshiba and Sanyo battery and electric drive technology providers, under the authority of Japan Defense Agency, producing six driven Japanese Army (wheel motor) + electricity extended-oil 105mm caliber assault guns hybrid drive technology demonstrator vehicle, manufacturing mute better performance for the Japanese navy, assault stronger, the extended-range hybrid drive + degree promoting the “black dragon-class” submarines AIP (air independent) of the cabin.
October 8, 2018, I wrote “Song Nan: judgments Japanese Navy active duty” shall Dragon “No. lithium-sulfur electrically driven submarine technique and tactics,” a text, to Japan naval equipment based on the world’s first extended-range lithium-sulfur batteriesHybrid drive “black dragon” class submarines tactics “Dragon should” sign. In “shall Dragon” program number is incremented hybrid drive lithium-sulfur battery energy density mounting on the submarine, far more than the energy density of 200Wh / kg civilian vehicle 2020 included in the lithium battery gauge level three yuan. Provided jointly by Toshiba and shallow soup lithium-sulfur batteries, making the Japanese naval equipment “Dragon should” submarine, drive efficiency more powerful, and increasingly tend EV drive mode.
Clearly, in some countries there is a global threat to China’s national interests, we were trying to accelerate the application of new energy technologies in the Army and Navy equipment. However, an important strategy for China to benefit from the identification of new energy industry chain development efforts in 2014, we have built the world’s most complete drive motor (200 kilowatt inter-axis motor 150 kilowatt wheel motors), battery (phosphoric acid lithium iron battery, a nickel-cobalt-manganese lithium battery), the vehicle level control system chain. Even in later switched to the “inner loop” state, the development of China’s new energy industry can still be pursued with vigor single-handedly.
This time, the program employed by hybrid drive technology HTF5700HEV heavy wheeled vehicles, emphasis plenty enough power is converted into a steady power output to 5 6 group or set of modular electric drive axle, obtained beyond the high reliability of the overall system is purely mechanical transmission system.
In my view, an extended-range hybrid drive technology without regard to cost, without regard to fuel consumption, more cattle X only consider the tactical advantage of technology to enhance the exchange, only military application is the most stickers the ultimate direction of closing.
Of course, require special attention, HTF5700HEV heavy wheeled vehicle increase the actual loading program verification hybrid drive technology, has at least four years. The entire technology and technology demonstration project vehicle may be time to promote at least three years ahead. Virtually, the intersection of which with some extended-hybrid drive uses the same technique (with plug function) over ONE. But, HTF5700HEV heavy wheeled vehicles, certainly not after the public appearance, there is a fire burning, or “off-axis” and other security issues.
