Electric wheel dump trucks for mining are large-scale transportation equipment used in the metallurgical mining field. They use electric transmission systems to replace traditional mechanical transmission devices. The model is powered by an engine that drives an AC generator to generate electricity. After rectification, the electricity is used to drive the wheels through a DC motor on the wheel side. It has technical characteristics such as large load capacity (generally exceeding 80 tons) and stepless speed regulation [1]. Its core structure eliminates traditional components such as clutches and gearboxes. It adopts an integrated design of traction generator and wheel-side reducer, which has advantages such as excellent traction performance and outstanding climbing ability (generally reaching a slope of more than 10%).
