Engine performance
◆ Dongfeng Cummins ECU adopted by Dongfeng JUWUBA is provided to customers by Cummins R&D center in East Asia. And optimized transient operation of the engine in accordance with the characteristics of engineering equipment, while the energy output at full load and speed change significantly.
◆ Low Fuel Consumption - Cummins XPI common rail high pressure fuel injection system and supercharged turbocharger, combined with cummins advanced cylinder design and electronic control system, greatly reduces fuel consumption, providing excellent fuel economy under various operating conditions. and application.
◆ Good reliability - the use of the world's leading engineering and design analysis tools, combined with Chinese users using the conditions, with the support of powerful sensors and electronic control system, stronger motor ability when running at high altitude, continuous operation at low temperature and large load capacity. minus 40 to 60 degrees Celsius, engine height of 5200 m can run freely.
Transmission performance
◆ Automatic electronic control, built-in torque converter, hydraulic retarder and planetary gear, with the function of hydraulic gear shifting, power/eco mode switching, lift backstop, lift speed suppression and other functions. Six speeds forward, one reverse, automatic locking in all speed ranges.
◆ The company adopts the world-famous Allison dump truck. The Allison gearbox is made in the USA and its reliability is very good.
◆ Improved handling - Continuous Power Technology ™ makes simple automatic transmission smooth continuous transmission of engine power to drive the wheels, even in harsh rough road conditions, and at the same time can provide remarkable acceleration, smooth movement, easy gear shifting, as well as precise traction control and performance manipulation.
◆ Cost reduction. Simplified maintenance. Regular routine maintenance simply changes the oil and filter.
◆ Improved fuel economy. The automatic transmission can select the best gears according to the vehicle load and road conditions to automatically save oil or increase vehicle power according to the need of the road conditions. When the vehicle is idling, the transmission will select a low engine speed to save fuel; Need to speed up to select dynamic shift mode. Lowering the gear train can be done automatically via the gearbox retarder to keep the vehicle at a reduced speed at all times, without excessive use of the brake.
suspension characteristic
◆ Suspension system - Designed to disperse traffic and shock loads, prolong frame life, more comfortable driving. Four independent self-contained variable speed nitrogen-oil cylinders, the suspension design absorbs shock in the most demanding applications. Cylinder with large pore diameter and low pressure nitrogen oil structure, less maintenance burden, long service life.
◆ The front cylinder has a trunnion angle preset, and the front camber angle cylinder front is mounted on the frame to play the role of the trunnion in a hurry, good handling, less maintenance workload.
◆ The rear cylinder can rotate the axle to absorb bending and torsional stress for bumpy and uneven traffic road to prevent the load from the main frame.
brake system
◆ Assembled the service brake, parking brake, car parking brake, emergency brake, retarder and VVEB, selecting the type of braking according to the need for braking to ensure safety.
◆ The parking brake is 80-90% transferred by the hydraulic retarder to reduce the use of the brake, otherwise it may cause brake failure and tire blowout due to overheating of the brake drum.
◆ Traditional braking has been changed, driver stress has been removed, endurance has been reduced. No need to frequently replace brake pads and prolong tire life, reduce maintenance costs.
◆ The exhaust brake controlled by independent dual circuit is used when the speed is less than 5km/h. There is no need to assemble the water spray device.
◆ When the air pressure is lower than 0.45MP, the emergency brake will work automatically. The parking brake is controlled by a brake switch.
Box section design Frame
◆ Use a fully fabricated box section welded together with a high strength plate that has a built-in bottom bumper, semi-closed portal beam, rear beam by aluminum calorific welding combing one-piece structure Through finite element load simulation on the frame, the stress intensity of the frame of reasonable rigidity is better.
Characteristics of the driving axle
◆ Using high-alloy casting shell, full-floating half-axle, reducer made with a single helical bevel gear reducer, and planetary reducer on both sides of the wheel.
Lift characteristic
◆ The lifting hydraulic system is independent of the hydraulic steering system, which is driven by a separate hydraulic pump.
◆ The system adopts hydraulic pilot control method: lift, drop, hold, float, four kinds of functions.
◆ Duplex four-level telescopic lifting cylinder on the outside of the frame, cylinder stroke is relatively small, good stability, has the function of forced body fall.
Tire specification
◆ Standard tires for construction equipment, tubeless, deep pattern. Wear resistance, cut resistance, more suitable for inland mountain roads. Special conditions, you can contact the tire manufacturer, adapt, get the best use effect.
Steering system
◆ With a median often closed full hydraulic steering, the largest steering angle of 38 °, when a crisis occurs, emergency power is supplied from the battery to provide emergency steering. The minimum turning radius is 9 meters.
Dump truck salon
◆ Panoramic windshield, wide view. The interior space layout is reasonable, spacious and bright, interior, instrument panel and control switch conform to ergonomic design.
◆ The cabin uses a new insulating material to provide a quiet working environment for the driver. The air suspension seat effectively dampens vibration, which can be installed optionally, the instrument panel is stable, reliable and transparent.
Structure of the intelligent GPS system
◆ The GPS intelligent system can provide many functions, such as maintenance management, fuel consumption, operation report, driver behavior analysis, equipment analysis report, making the tedious operation management simple, easy and efficient
Remote terminal communication system + data platform
Centralized lubrication system
◆ A centralized lubrication system is a system that accurately distributes the required amount of lubrication to multiple lubrication points.
Tire pressure monitoring system (TPMS)
◆ Currently, TPMS provides efficient monitoring of tire pressure and temperature at any time. , Timely monitor tire temperature and pressure change at normal times, if you have any abnormal situation, through the host that received the abnormal warning. Make sure tires are under acceptable pressure and temperature for operating conditions to reduce fuel consumption and increase tire life.
◆ Tire pressure in case of insufficient, easy to increase tire wear and shorten the service life and increase the likelihood of a flat tire. If the tire pressure is too high, it will reduce tire grip. Every 3 psi reduction in tire pressure increases fuel consumption by approximately 1%. It is generally believed that increasing tire pressure by 25% shortens tire life by about 15-20%, and tire pressure reduces tire life by 25%, reducing by about 30%. Vehicle tire temperature is higher, the lower the strength of the tire, the greater the deformation, tire wear will also increase accordingly, also reduce the service life.
Automatic detection of clogged air filter
◆ Installed Fleetguard filter and imported Bote pre-filter, manufactured by Dongfeng and US Fleetguard joint venture, which are the perfect combination to achieve engine intake air purity up to 99.9%, and air intake resistance alarm can immediately inform the user can maintain air filters and can reduce unnecessary maintenance, improve efficiency and extend filter element life.
