Abrasion detecting and warning device for wet disc

The invention relates to an abrasion detecting and warning device for a wet disc, and belongs to the technical field of braking devices. An abrasion detecting and warning device for a wet disc comprises a piston moving axially and a piston end cover which is connected with the piston in a matched mode and moves along with the piston, a measuring device which is connected with the piston and synchronously moves along with the piston is arranged in the piston end cover, a fixing seat is arranged on the piston end cover, and the fixing seat is in interference connection with the measuring device. The device is compact in structure, is especially suitable for braking scenes with limited space, can detect the operation conditions of equipment, such as a wet disc brake, a clutch and the like, which can be abraded under the condition that the equipment is not stopped and is not disassembled, installed and tested, can amplify the abraded equipment, and can timely discover very small abraded equipment.
