Pure Electric Wide Body Dump Truck For Mining

Features：

• Mining large capacity battery;

• 300~450kwh, multiple combinations;

• Compact structure, the powertrain is close to the drive axle;

• When driving, the auxiliary control system is conducive to waterproof and dustproof, and improves the service life;

• The frame type design of the power battery box and the lower frame type reduce the deformation of the frame, reduce the dynamic frequency and amplitude of the battery box, and improve the service life of the whole vehicle.

High Strength Rigid Frame

• Fully welded rigid frame, the longitudinal beam is welded into a box structure from four plates, namely, the upper and lower wing plates and the inner and outer webs. The connection between the torsion beam and the longitudinal beam is strengthened by connecting plates. The frame as a whole has the advantages of high rigidity and strong torsional resistance. At the same time, the subframe is not required, and the weight center of the whole vehicle can be reduced

Hydro Pneumatic Spring Suspension

• The hydro pneumatic spring structure is suspended at the front, and the elastic element is a hydro pneumatic hybrid spring structure. The biggest feature of hydro pneumatic spring is that its stiffness can change according to the load, and the front axle is positioned through the pull rod, which has the characteristics of accurate axle positioning and good driving comfort.

• The hydro pneumatic spring has a wide frequency range, which can effectively absorb the impact of the chassis on the whole vehicle, improve the service life of the frame and reduce the maintenance cost

Full Hydraulic Steering

• The full hydraulic steering system features light steering. At the speed of 12r/s, the steering force is less than 30n. Compared with the one-way machine or two-way machine scheme, the steering force is only 20% - 40% of the latter, and the failure rate is low;

• After the power source of the vehicle steering system is lost, the energy reserve of the vehicle can be tested to realize the full steering action of 2 turns, complete the stable parking and maintenance of the vehicle, ensure the safety of the vehicle, and meet the requirements of the national standard of full hydraulic steering.

Power Battery

• CATL era ultra high energy density battery, battery density 170wh/kg;

• 1C high charging rate and high-power double gun charging pile are adopted at the same time, and the charging time can be shortened to 1 hour;

• IP68 super protection grade;

• 5-year warranty, attenuation not higher than 20%;

• More than 4000 cycles in 8 years;

• Water cooling temperature control, maintain the best working temperature of the battery: 28~35 ℃;

• Mining large capacity battery 250~450kwh, multiple combinations

Power Motor

• Dual motor 2-speed powertrain, strong power, efficient output, green and environmental protection.

• Double permanent magnet synchronous motor structure;

• The motor is cooled by oil and lubricated actively without maintenance;

• Two speed ratios and two shift forks realize alternate shifting without power interruption:

• High torque, wide speed, high speed gear can meet the requirements of working conditions, and there is basically no need to shift gears in the middle;

• Two stage deceleration reduces mechanical energy loss;

Passenger Car Control System:VCU Control System

• Special VCU for electric wide body dump truck, using high-power battery, high torque gearbox, mine low-speed working conditions - high temperature, large dust, continuous steep slope, etc;

• 4-way can bus, with gateway function and real-time data exchange;

• Control strategy: safety first, economy first, efficiency equally, and comprehensive functions;

• Rich software architecture: vehicle status management, torque management, power management, signal transmission and processing; Bottom layer signal processing, accessory module management, double pedal and vehicle dynamic information calculation;

• Compact design +360 ° shielding protection.

Braking Energy Recovery

• Level 5 energy recovery gear to ensure efficiency and economy; The operating lever is arranged under the steering wheel for easy operation;

• When the slope reaches more than 8%, the recovery capacity basically meets the driving needs of vehicles; It has been verified that under heavy-duty downhill conditions, the average annual power consumption of a single vehicle is about 200000 kwh. Relying on energy recovery, 100000 kwh can be saved, and 90% of the power can be saved.
