The invention provides a wet type multi-plate push type sliding clutch. The wet type multi-plate push type sliding clutch is characterized in that a sliding mechanism B is arranged between a clutch pressure plate and a clutch spline sleeve, a sliding mechanism A is arranged between the clutch spline sleeve and a lifting plate, the sliding mechanism A comprises first convex blocks arranged on the clutch spline sleeve and second convex blocks arranged on the lifting plate, the first convex blocks and the second convex blocks are correspondingly arranged on the adjacent sides of the clutch splinesleeve and the lifting plate, at least one surface of each first convex block and at least one surface of each second convex block are arranged in a mode of inclining towards an input shaft of a gearbox, the inclination angles of the inclined surfaces of the first convex blocks and the inclination angles of the inclined surfaces of the second convex blocks are the same, the sliding mechanism B comprises third convex blocks on the clutch pressure plate and corresponding grooves formed in the clutch spline sleeve, the third convex blocks are matched with the grooves, at least one surface of each third convex block inclines towards the surface of the clutch pressure plate, and the grooves and the third convex blocks are connected through the inclined surfaces in a sliding mode. According tothe wet type multi-plate push type sliding clutch, the strength of a vehicle gear shifting knob can be reduced, and the stability during high-speed gear reduction of a vehicle can be improved.
