2, AC-to-DC driving system.Driving engine drives alternating current generator and sends the controller alternating current, is rectified into direct current (DC) through silicon power rectifier, resupplies to drive the DC wheel hub motor that is positioned at trailing wheel.This actuation techniques is comparatively tradition, proven technique comparatively, also has a wide range of applications on the electric drive wheel mine truck at present.But with straight-dc drive system is the same, all uses DC motor, has certain defective.
3, AC-DC-AC spreads moving system.The maturation of handing over the orthogonal drive technology to be accompanied by the high power contravariant device is born, and is present up-to-date technology.Hand in the orthogonal system, driving engine drives alternator generation, the alternating current that sends is transformed into direct current (DC) through silicon controlled rectifier, filter unit, pass through inverter again, become the alternating current of voltage magnitude, frequency adjustable, driving is positioned at the wheel hub electric motor of trailing wheel then, thereby makes alternating-current motor/AC motor realize luffing, frequency control.The characteristics of this transmission are simple in structure, and the alternating-current motor/AC motor size is little in light weight, and system is reliable, and is easy to maintenance.
As everyone knows, vehicle is when turning, and the both sides tire is positioned on the different turn radiuss, and differential gear assurance both sides tire is all fitted the phenomenon of not skidding with ground between therefore needing to take turns.
For example Chinese invention patent 200680035965.8 provides the electric drive system that is used for construction machinery and equipment, comprise driving engine, electrical generator, at least one electrical motor and control system, the driving system that this patent provides still adopts differential gear between traditional mechanical type wheel, mechanical differential gear box complex structure.
