Oil pressure connector of front end of crankshaft

The invention discloses an oil pressure connector of the front end of a crankshaft. The oil pressure connector comprises a connector body, damper mounting bolt holes and belt pulley mounting bolt holes; the connector body is shaped like a sleeve and is provided with a central crankshaft hole, the central crankshaft hole is a conical hole, and the inner wall of the conical hole is provided with an oil pressure oil groove which is conically connected with the crankshaft; one end of the connector body is provided with a radial flange; the damper mounting bolt holes are evenly arranged along the circumference of the surface of the radial flange; the belt pulley mounting bolt holes are evenly arranged along the circumference of the end surface of the other end of the connector body. Because the oil pressure connector of the front end of the crankshaft is conically connected with the crankshaft in an oil pressure manner, the torque transmitted by the front end of the crankshaft is high, the power of a driving accessory is high, and the driving accessory is reliable.
