Description
technical field [0001] The invention mainly relates to the technical field of mining equipment, in particular to a traction system of a hybrid electric wheel dump truck. Background technique [0002] The environment of most domestic mines is harsh, and the on-site working environment of electric wheel mining vehicles is not electrified. The mainstream electric wheel mining vehicles are powered by diesel engines. The diesel engine and generator are collectively referred to as the power pack, which together provide electric energy to the electric wheeled mining vehicle. The traditional electric drive system is mainly composed of five parts: diesel engine, generator, converter, braking resistor, and hub motor. However, as the power of the diesel engine increases, its technical difficulty becomes more and more difficult, which is mainly reflected in the control algorithm of the diesel engine. Moreover, due to the particularity of diesel engines, electric wheeled mining vehicle...
