UPPER SPRING PAD OF A SUSPENSION DEVICE TO IMPROVE THE FREEDOM DESIGN THROUGH INCREASING THE FREEDOM CONTACT OF A SUPPORTING PLATE AND A SPRING

摘要

PURPOSE: An upper spring pad of a suspension device is provided to improve durability and reduce noise through minimizing the contact surface.;CONSTITUTION: An upper spring pad(100) of a suspension device comprises a hollow coupling unit(110) and a supporting plate(120). The supporting plate is formed along the rim of the hollow coupling unit. One portion surface of the supporting plate comprises a stopping step portion(121) and other one portion is formed into a spiral inclined plane(123) based on the hollow coupling unit and the stopping step portion has height difference through connecting the starting point and the end point of the spiral inclined plane.;COPYRIGHT KIPO 2012
