HEAD GASKET WITH THE DOUBLE HALF BEAD STRUCTURE OF A T-JOINT UNIT CAPABLE OF INCREASING THE FOLLOWING CHARACTERISTIC ACCORDING TO THE BEHAVIOR OF A CYLINDER BLOCK AND A CYLINDER HEAD THROUGH A GAP GENERATED BY THE DOUBLE HALF BEAD

摘要

PURPOSE: A head gasket with the double half bead structure of a T-joint unit is provided to enhance air-tightness of the T-joint unit since the charging effect of liquid sealant is increased by a space, which is formed by a cylinder head or a cylinder block and upper and lower land surfaces.;CONSTITUTION: A head gasket with the double half bead structure of a T-joint unit comprises a half bead(102) and an erasable bead(104). The half bead is formed as a certain slope along edge in the direction of the space of a chain case from one end making contact with a chain case. The erasable bead comprises a slope in the opposite direction to the half bead. The erasable bead is formed in parallel with the half bead from one end making contact with the chain case. The other end of the erasable bead makes contact with edge separated from the T-joint unit and is removed.;COPYRIGHT KIPO 2012
