3 Types and composition
3.1 Types
The haulage driving unit may be divided into electrical speed-adjustable haulage driving unit and hydraulic speed-adjustable haulage driving unit according to the speed adjustment mode.
3.2 Composition
The haulage driving unit is composed of haulage adjustable speed unit (hereinafter referred to as adjustable speed unit) and haulage transmission unit (hereinafter referred to as transmission unit). In case of electrical adjustable speed mode, the adjustable speed unit and the transmission unit are two independent components; in case of hydraulic adjustable speed, the transmission unit is divided into a front transmission box (in front of the hydraulic pump) and a rear transmission box (behind the hydraulic motor). The adjustable speed unit and the transmission unit are generally combined in a box, and the rear transmission box may also be an independent component.
