The invention relates to a wet type clutch with a pressure stabilizing function. The wet type clutch comprises a main shaft, a clutch piston cylinder, a clutch piston, a clutch outer hub, a clutch inner hub, a friction sheet, a dual patch, a spring assembly and an LD valve pressure stabilizing device, wherein the LD valve pressure stabilizing device mainly consists of an LD valve piston cylinder, an active piston, a passive piston and an LD valve spring. The wet type clutch is provided with the LD valve pressure stabilizing device, the effect of stabilizing the pressure inside the clutch can be achieved, particularly under the high-speed operation conditions, the pressure fluctuation, generated by rotating centrifugal force, of oil liquid inside the clutch can be reduced, the clutch pressure can maintain a stable state, the reliability of the clutch is improved, and the service life of the clutch is prolonged.
