Clutch abrasion indicating sheet structure

The invention discloses a clutch abrasion indicating sheet structure. The clutch abrasion indicating sheet structure comprises a straight rod. The straight rod is made of stainless steel. The axis of the straight rod and the axis of a clutch boost cylinder are in the same direction. The two ends of the straight rod are located inside and outside a cavity of the boost cylinder respectively. An indicating sheet is arranged at the end, located outside the cavity of the boost cylinder, of the straight rod and is a disc-shaped plastic piece. A through hole is formed in the middle of the disc face of the indicating sheet and used for being connected with the straight rod in a sleeving mode. An inner groove is formed in the indicating sheet from the lateral side to the center. A steel wire clamp spring is arranged in the inner groove, is connected to the straight rod in a sleeving mode and is in interference fit with the straight rod. A cylinder body of the boost cylinder is provided with a fixing base. The straight rod penetrates through the fixing base. The indicating sheet and the fixing base are provided with measuring faces which are perpendicular to the axis of the straight rod and are used for measuring the distance between the indicating sheet and the fixing base. The clutch abrasion indicating sheet structure has the advantages that according to the scheme, the structure is simple, use is reliable, bidirectional movement can be achieved, corroding is avoided under the severe working condition, and falling is avoided after long-time vibration.
