Years ago，China's Heavy Truck Digests Steyr's Engines Through Introduction、Gearbox、The core technology of the three major parts of the axle，Gradually formed“Gold dynamic transmission system”，Raise the power level of domestic heavy Trucks to300 horsepower，It has laid a foundation for China's heavy Truck to become bigger and stronger.。A large number of wide-body Vehicles using heavy truck technology have also been transplanted.“Gold dynamic transmission system”，And continue to be successful。
In recent years, the wide-body Dump Truck has gradually developed to large tonnage.，“Gold dynamic transmission system”More and more unable to do what they want，Mine construction urgently needs to upgrade the dynamic transmission system.。According to the market demand, Zoomlion, which inherits the technical background of scientific research institutes,，Supported by the National Key Laboratory，Utilize its own Vehicle integration、Match technology and integrate industry supply chain，United Yuchai and other domestic mainstream parts supporting enterprises，More suitable for open-pit mines “Diamond dynamic transmission system”，Its technology is more advanced.，More power，The economy is better，Higher reliability。
“Diamond dynamic transmission system”Redefines the power transmission standard for wide-body Dump Trucks，Include
16-liter high-power engine，Rated power above 775 HP
8-speed transmission，Input torque 2650N •mAbove
Including automatic compensation function and long-term sealing performanceMaintenance-free drive shaft
Heavy-duty axle，Wherein, the load of front axle is 35t，Drive axle single axle driving force 180kN•mAbove
Reinforced all-steel radial tire，Belt more than 4 layers，Wire diameter 2.24mmAbove
AICombined braking，IncludeAIIntelligent braking system+In-cylinder braking（300kW）+Hydraulic slowness（400kW）+Ф500*250 drum brake（Single-axle standard braking force 90kN•mAbove）
Among，The 16-liter high-power engine has a power of775 horsepowerAbove，Make the specific power of the whole car reach the level of classic cars.，As a result, the Vehicle performance has been greatly improved.，Not onlyOperation speed increased by 10%，And the engine works in a more ideal range.，Fuel consumption is lower than that of low-power vehicles.。Under the same conditions，Each vehicle can run several more cycles per day.，Create more value for users。High strength body、Application of High Efficiency Combustion Technology，Make itSafe and reliable，Economical and fuel-efficient，High temperature、High and cold、Good adaptability to extreme environments such as plateau。

8-speed transmission，The input torque is large，Achieve2650N.m。Designed with high safety factor，Shell、The gear has high strength，Adopt active lubrication to improve gear life and comprehensive transmission efficiency，Meet the requirements of severe working conditions of the mine。The maximum braking torque of the equipped hydraulic retarder is large.，The corresponding speed is lower，Better torque at low engine speed，The response of opening and closing is also more rapid.。
High-load axle is made of high-strength material，The carrying capacity has been greatly improved，Better cold resistance，Time to first failure increased by more than 2 times。Through shaft、Main reducer and axle shaft gear、Front axle kingpin、Optimization design is adopted for steering knuckle and other structures.，Increase strength、Reliability and life。The front axle adopts35 tons of bridge load，Increased load carrying capacity 40%，Meanwhile, the safety during emergency braking is improved.。
The special tire for mine adopts strengthening design according to the working condition of mine.，Belt more than 4 layers，Ply wire diameter 2.24mm，Tire OD increased by 2%，Weight increase 3%，These strengthening measuresThe bearing capacity and durability of the tire are improved，The operation cost of the user is reduced.。
Braking system is the key to the safe operation of vehicles.，You can drive and you can stop.。“Diamond dynamic transmission system”By piggybackA new generationAIIntelligent braking system，Capable of automatically triggering in-cylinder braking and hydraulic damping，Linkage control of hydraulic buffer and in-cylinder brake，The braking capacity is greatly improved.，Meanwhile, the loss of the friction plate is reduced.。After applying the technology,，Significant improvement in engine overspeed，Running time above 2300 rpm reduced by 76%Above，2000-2300 RPM run time reduced by 49 percent%。

“Diamond dynamic transmission system”Fully designed and matched to mine requirements，The power and safety of the wide-body dump truck reach the level of the classic dump truck at one stroke.，The whole system has been verified by bench test and field test.，Compared with the whole vehicle of the previous generation productOperation efficiency increased by 30 percent%，Fuel consumption per ton kilometer reduced by 14%。“Diamond dynamic transmission system”Keep it“Gold dynamic transmission system”Mature and reliable、Key attributes of full autonomy，FromDriving comfort、Fuel economy、Driving safety、Ease of maintenanceDefine a new generation of mining wide-body truck from multiple angles.，Its excellent quality and value have been accepted by the market.。
Meng Qingyong, general manager of Mining Machinery Division of Zoomlion, said.，“Diamond dynamic transmission system”The wide-body dump truck can maintain the highest cost performance while developing towards large-scale.，Become the best choice for mine transportation。Zoomlion will continue to develop products that exceed user expectations.，Promote the continuous progress of the industry。Jiang Fei, Party Secretary of Guangxi Yuchai Machinery Co., Ltd., said.，“Diamond dynamic transmission system”It is a concentrated reflection of new quality productivity in the field of mining.，Mining Machinery supporting enterprises will continue to optimize products，Enhance higher value competitiveness for mine users。
Zoomlion has a long and deep mine gene.，1987，“Complete sets of equipment for open-pit mines with an annual output of 10 million tons”Major technical equipment award of the State Council。2011，The world's largest 10,000-ton reclaimer is put into use in the Vale project。Zhonglian Mining Machine insists“Technology is the root，Product-based”The idea of innovation，Provide customers with one-stop solutions for mines，Products cover mining drilling rigs、Mining Excavator、Electric drive dump truck、Wide-body dump truck、Mining Bulldozer、Mining equipment such as mine Sprinkler，Full range of mobile crushing and screening stations、Fixed crushing and screening line and material conveying equipment, etc.，With the most complete Mining Machinery product line。（Advisory Hotline：400-800-0157）
