41 FRP leaf spring suspension US623938 1984-06-25 US4598900A 1986-07-08 Masami Yamamoto; Kenichi Sekiyama; Kiyoaki Kuwayama
The invention relates to a FRP leaf spring suspension for an automobile including a FRP leaf spring body interposed between a hat-shaped retainer having flanges at its free ends and a U bolt seat having opposed flanges through a rubber pad at its longitudinally central portion. The FRP leaf spring body is fixed through a spring seat to an axle housing by a U bolt passing through mating holes formed in flanges of the retainer and the U bolt seat. A reinforcing fiber impregnated with resin is wound around a central portion of the FRP leaf spring body and is fixed thereto to form unevenness on a surface of the FRP leaf spring body, thereby distributing frictional force between the FRP leaf spring body and the rubber pad uniformly on the frictional contact surface of the FRP leaf spring body, and preventing stress concentration from being generated in the FRP leaf spring body. In another mode, there are formed each unevenness on an upper and a lower surface of the central portion of the FRP leaf spring body, a lower surface of the retainer, and an upper surface of the U bolt seat, thereby preventing stress concentration from being generated in the FRP leaf spring body.
