The utility model discloses a friction gasket for a driving shaft assembly, which is mounted between a bell housing of a universal joint and a bearing of a hub unit and comprises a gasket body. The gasket body comprises a base body made of a cold-roll steel sheet, a nickel plating layer arranged outside the base body in a wrapping mode and diamond plating layers arranged on the end faces of the two opposite sides of the nickel plating layer, and each diamond plating layer comprises a plurality of diamonds embedded in the nickel plating layer. According to the utility model, the diamond plating layers formed by the plurality of diamonds are arranged on the end surfaces of the two sides of the gasket, so that the friction coefficient of the end surfaces of the gasket can be effectively increased, and meanwhile, the diamonds on the end surfaces of the gasket can be correspondingly clamped into the end surfaces combined with the hub unit and the bell housing to generate a micro-scale interlocking effect; therefor
