Embodiment Construction
[0030] The present invention will be further described below with reference to the accompanying drawings.
[0031] like figure 1 As shown, a 100-ton pure electric-driven mining dump truck includes a frame 1, a walking platform 2, a cab 3 arranged on the walking platform 2, a power system and a cooling system.
[0032] like Figure 5 As shown, the power system includes a power battery, a high-voltage box, a converter cabinet 7, an AC load, a DC load and a DC24V load, and the power supply is supplied to the AC load, DC load and DC24V load through the high-voltage box and the converter cabinet 7 . The AC load includes a traction motor 4, a steering motor and a lift motor. The traction motor 4 drives the rear wheel through a transmission shaft and a drive axle, the steering motor drives a steering pump, and the lift motor drives the lift pump. The DC load includes a PTC heater, an air conditioner compressor and a battery water cooling unit, and the battery water cooling unit co...

A 100-ton pure electric drive mining dump truck comprises a frame, a walking board, a cab arranged on the walking board, a power system and a cooling system. The power system comprises a power battery pack, a converter cabinet, a traction motor, a steering motor, a steering pump, a lifting motor and a lifting pump, power electricity supplies power to the traction motor, the steering motor and the lifting motor through the high-voltage box and the converter cabinet, and the power battery pack comprises a first battery box set and a second battery box set; the first battery box group is mounted in the middle of the frame and in front of the gantry through a mechanical bracket; the second battery box group is mounted on the outer side of the middle part of the frame; the cab is arranged on the left side of the walking board, the converter cabinet is arranged on the right side of the walking board, the traction motor is installed in the middle of the frame and behind the gantry, and the steering motor, the steering pump, the lifting motor and the lifting pump are installed on the inner side of the gantry. A high-power traction motor direct drive system is arranged, and a large-torque traction motor is adopted, so that energy loss caused by transmission of a gearbox is reduced, the problem that the gearbox needs to be maintained regularly is solved, and the whole vehicle is uniform in layout stress.
Description
technical field [0001] The invention relates to a dump truck, in particular to a 100-ton pure electric-driven mining dump truck. Background technique [0002] The 100-ton mining dump truck is a kind of off-highway vehicle used in open-pit mines and large-scale engineering construction sites. At present, mining trucks basically use diesel engines as power-driven vehicles. With the improvement of the energy density of the power battery, the reduction of the unit cost, and the improvement of the reliability of the power battery system, the electrification of mining dump trucks has become a trend. [0003] At present, there are two main types of 100-ton mining dump trucks according to different transmission forms: [0004] One is mechanical transmission. The whole vehicle is driven by a diesel engine and a gearbox. The diesel engine transmits power to the wheels through the gearbox, transmission shaft, differential and wheel reducer. Mechanical transmission mining truck: fuel ...
