Automatic compensation device for clutch abrasion for locomotive

The invention discloses an automatic compensation device for clutch abrasion for a locomotive. The automatic compensation device is arranged between a clutch separation bearing and a clutch execution mechanism. The automatic compensation device comprises a casing assembly, a self-locking device, a limit device and a pull rod. The self-locking device is arranged in the casing assembly and is a one-way self-locking device. The automatic compensation device achieves abrasion automatic compensation of a clutch under the effect of diaphragm spring piece and outputs certain pull force to provide preload force for the separation bearing. The execution mechanism achieves the automatic compensation function after the clutch is abraded. Simultaneously, preload force for separating a shifting fork and the separation bearing is provided. The automatic compensation device is simple and reasonable in structure, high in control accuracy, sensitive in reaction, stable in manipulation, low in cost and long in service life, ha
