Technical Introduction

1. Power system

The power system adopts Volvo Euro V emission standard engine, and the exhaust system adopts catalytic reduction treatment to save energy and protect the environment; Enough power reserve is available for plateau construction. The engine cooling system uses an electronically controlled piston variable displacement pump and a fixed displacement gear motor as the power source, and the engine controller controls the displacement of the variable displacement pump according to its own signal, thereby controlling the motor speed, and finally realizing the engine thermal balance.

Engine model: TAD1380VE
Emission standard: Euro V
Rated power: 375kW/1900rpm
Maximum torque: 2595Nm/1200rpm
Fuel tank volume 750L

2. Transmission system

The transmission system adopts mature Dana torque converter and electric shift gearbox, with large traction and strong climbing ability. The axle is equipped with spring brake and hydraulic release wet spring brake to realize the integration of working brake, parking brake and emergency brake, simplify the brake hydraulic circuit, and improve the braking reliability and safety.

Transmission gear and speed ratio: front four rear four, 4.07 2.26 1.29 0.71
Axle speed ratio: 32.58
Traction force: 431kN
Maximum speed (heavy load): 25.9km/h

3. Hydraulic system

The working system and steering system adopt load feedback variable system and hydraulic confluence, and the control mode is electro-hydraulic proportional pilot control. The axle braking and cooling pump is a variable system, which controls the driving and braking in two ways. The steering pump is connected in series with the brake pump and is placed at the torque converter power intake.

Maximum pressure of steering system:
Maximum flow of steering system: 29.5MPa

209L/min
Maximum pressure of working system: 29.5MPa
Maximum flow of working system: 209L/min
Rated pressure of brake pump: 28MPa
Rated flow of brake pump: 51L/min
Volume of main oil tank: 460L

4. Electric control system

The electric control system uses CAN bus communication, integrated electronic handle to control the electro-hydraulic proportional valve, realizing the walking control (forward, backward, steering, shift) and working device control (boom lifting and bucket overturning) of the scraper. Monitor and display engine operating parameters, hydraulic system parameters and vehicle driving information, and be able to intelligently diagnose and alarm faults.



5. Frame

The structure of the frame is articulated, and the connection of the articulated part refers to the loader type structure: two tapered roller bearings are used at both the upper and lower sides. The articulation center of the front and rear frames is arranged in the middle of the wheelbase, which has good stability. The rear wheels and front wheels share the same track, so that the turning radius is smaller, the driving resistance is small, and the tire wear is small. The rigid suspension structure is adopted between the front and rear frames and the axle to reduce the vehicle height and adapt to the low roadway environment in the mine. The main board of the frame is made of Q460C, which has a high safety factor and can withstand high strength impact and vibration.
