Engine performance
|
◆The Dongfeng Cummins electronically controlled engine adopted by the Dongfeng Big Mac is "tailored" by Cummins East Asia Technology R&D Center for local customers, and the transient operating conditions of the engine are specially optimized for the characteristics of construction machinery operation. There is still plenty of motivation despite changes.
|
|
◆Ultra-low fuel consumption-Using Cummins XPI ultra-high pressure common rail fuel injection system and large-flow turbocharger, combined with Cummins advanced power cylinder design and electronic control system, greatly reduce fuel consumption and ensure that the engine is in different working conditions and applications Excellent fuel economy.
|
|
◆Excellent reliability-using the world's leading engineering technology and analysis tools combined with the design of Chinese users, with the support of powerful sensors and electronic control system, the engine has stronger high altitude operation ability, low temperature operation and heavy load Continuous operation capability, the engine can run freely at minus 40 to 60 degrees Celsius and 5200 meters above sea level.

Gearbox
| Transmission performance |
◆Electronic control automatic gear shifting, hydraulic torque converter, hydraulic retarder and planetary gear transmission are integrated, with hydraulic slow travel, power/economy mode switching, lifting and reverse gear interlocking, lifting and shifting inhibition and other functions. 6 forward gears, 1 reverse gear, the transmission can be automatically locked in all gears
|
|
◆The company adopts the world-famous automatic gearbox for mining trucks—Allison gearbox. Allison gearbox is produced in the United States and has super reliability.
|
|
◆Improved controllability-Uninterrupted power technology makes the fully automatic gearbox simple and smooth uninterrupted transmission of engine power to the driving wheels, even in harsh and rugged road conditions, it can still achieve excellent acceleration and driving smoothness, ensuring The vehicle is easy to shift gears, with precise traction control and good handling performance.
|
|
◆Reduce costs and simplify maintenance-routine maintenance of the gearbox only requires regular replacement of oil and filter elements.
|
|
◆Improve fuel efficiency-automatic transmission can select the best gear according to vehicle load and road conditions, automatically save fuel consumption or increase vehicle power according to road conditions. When the vehicle is idling, the gearbox will select a lower engine speed to save fuel consumption; when it needs to accelerate, it will select the power shift mode. The gearbox can also be automatically downshifted and output through the gearbox retarder, so that the vehicle can maintain a certain downhill speed without excessive use of brakes.

Suspension system
|
Suspension characteristics
|
◆The suspension system is designed to disperse the impact caused by the transportation road and loading, extend the life of the frame, and make driving more comfortable. Four independent self-contained, oil-gas, variable rebound suspension cylinders are designed to absorb impact in the most demanding applications. The cylinder body adopts a large-aperture, low-pressure nitrogen/oil structure, with less maintenance and long life.
|
|
◆The front suspension is equipped with the front cylinder with the pre-set caster angle and front wheel camber angle on the frame, which acts as the kingpin when steering, with good maneuverability and less maintenance.
|
|
◆The rear suspension can swing with the vehicle bridge to absorb the bending and torsion stress generated on the uneven and rough transportation road surface, so that the stress will not be transmitted to the main frame.
|
Braking System
|
Braking System
|
◆There are six modes of service brake, parking brake, parking brake, emergency brake, hydraulic slow travel, and in-cylinder brake. Different braking modes can be adopted according to driving conditions, which is safe and reliable.
|
|
◆80-90% of service brakes are implemented by hydraulic retarders, which reduces the risk of brake failure and tire explosion caused by excessive brake drum temperature caused by frequent use of brakes. Easy and safe.
|
|
◆Change the traditional braking and operation methods to relieve the driver's tension and reduce the fatigue strength. There is no need to frequently replace the brake pads, extend the life of the tires, and reduce maintenance costs.
|
|
◆Exhaust brake adopts independent dual-circuit control, exhaust brake is used only when the speed is lower than 5km/h. No need to install sprinkler, safe, economical and environmentally friendly.
|
|
◆When the air pressure is lower than 0.45mp, the emergency brake will automatically take effect. The parking brake is realized by operating the brake switch.
|
Frame-full box section design
|
Frame
|
◆Using box-shaped variable cross-section and other stress frame structure, welded by high-strength steel plate, with integral front bumper, semi-enclosed gantry beam, and the rear beam adopts a cast-welded integrated structure. The finite element analysis of the frame through simulated loading shows that the frame is reasonably stressed and has good strength and rigidity. |
Drive axle
|
Drive axle characteristics
|
◆Using heavy-duty high-alloy cast shell, full-floating semi-shaft, the reduction device is composed of a primary reducer with a spiral bevel gear reduction and a wheel-side reducer with planetary gears on both sides of the wheel.
|
Lifting system
|
Lifting system characteristics
|
◆The lifting hydraulic system is independent of the steering hydraulic system and is driven by a separate hydraulic pump.
|
|
◆The system adopts hydraulic pilot control mode, with four functions of lifting, lowering, holding and floating.
|
|
◆External dual-cylinder four-stage telescopic lifting device, the cylinder stroke is relatively small, the stability is good, and it has the function of forcibly lowering the cargo box.

Centralized Lubrication System
|
Centralized Lubrication System
|
◆The so-called centralized lubrication system refers to a system that accurately supplies the required amount of lubricating grease to multiple lubrication points from one lubricating grease supply source.
|
Infinite tire pressure monitoring system
|
Infinite tire pressure monitoring system
|
◆Unlimited tire pressure monitoring system is currently the only device that can effectively monitor tire pressure and temperature at any time. It can monitor the changes in tire temperature and pressure at any time. If any abnormal situation occurs, it will issue an abnormal warning through the receiving host to ensure that the tires are always Run under reasonable pressure and temperature conditions to reduce fuel consumption and increase tire life.
|
|
◆When the tire pressure is insufficient, it is easy to increase the wear of the tire, thereby reducing the life span and increasing the chance of a tire blowout. If the tire pressure is too high, it will reduce the tire grip. Every 3PSI decrease in tire pressure will increase fuel consumption by more than 1%. It is generally believed that the tire pressure increases by 25% and the tire life is reduced by 15-20%, and the tire pressure is reduced by 25% and the tire life is reduced by 30%. The higher the temperature of the vehicle tire, the lower the strength of the tire, the greater the deformation, the tire wear will increase, and the service life will also decrease.

Self-checking air filter
|
◆Using the Fleetguard air filter, a joint venture between Dongfeng Company and Fleetguard Company of the United States, and the original imported Tebo pre-filter, the perfect combination of the two can make the engine intake air cleanliness up to 99.9%. Reminding the car owner to maintain the air filter at a time can reduce unnecessary maintenance, improve efficiency and increase the service life of the filter element.
