An axle mount construction for a fiber reinforced resin leaf spring which includes a clamping plate and a generally U-shaped clamping member. The clamping member has a web and side walls that define a longitudinal channel and flanges extend laterally from the side walls and are disposed flatwise against the side edges of the clamping plate. A pair of resilient rubber-like inserts are disposed within the channel and define a longitudinal passage to receive the leaf spring. Each insert includes a web and a pair of side walls. At least one side wall of the clamping member has an undulation and the corresponding side wall of the insert has a mating undulation. The web of the clamping member and the clamping plate have elongated openings and the outer surfaces of the webs of the resilient inserts have projections that are received in the openings. The ends of the inserts project longitudinally beyond the clamping members and are tapered inwardly toward the leaf spring.
A mounting construction for attaching a fiber reinforced resin leaf spring to a vehicle, comprising a pair of clamping members defining a longitudinal channel, resilient insert means disposed within the channel and defining a longitudinal passage, a fiber reinforced resin leaf spring disposed within the passage, at least one outer surface of said insert means means having an undulation and a corresponding inner surface of one of said clamping members having a similar undulation to mate with the undulation of said insert means, at least one of said clamping members having an opening extending therethrough and elongated in a lateral direction, said opening being bordered by a flange that extends in a direction away from said spring, and a laterally elongated projection on said insert means and disposed in the opening to resist relative longitudinal movement between said clamping members and said insert means.
A mounting construction for mounting a fiber reinforced resin leaf spring to a vehicle, comprising a clamping plate, a clamping member having a generally U-shaped cross section and composed of a central web and a pair of side walls extending from opposite sides of said web, said web and side walls defining a longitudinal channel, said clamping member also having a pair of laterally extending first flanges extending laterally from said side walls and disposed flatwise against said plate, at least one side wall of said clamping member having a longitudinally extending undulation, a pair of resilient inserts disposed within said channel, each insert having a central web and a pair of side walls, said inserts in combination defining a longitudinally extending passage, a fiber reinforced resin leaf spring disposed within said passage, the outer surfaces of the side walls of the inserts having undulations to mate with the undulations on said clamping member, the web of said clamping member having a laterally elongated opening extending therethrough, said opening being bordered by a second outwardly extending flange, and laterally elongated projection on the web of one of said inserts and disposed within said opening.
A mounting construction for attaching a fiber reinforced resin leaf spring to a vehicle, comprising a pair of clamping members defining a longitudinal channel, resilient insert means disposed within the channel and defining a longitudinal passage, a fiber reinforced resin leaf spring disposed in the passage, at least one outer surface of said isnert having an undulation and a corresponding inner surface of one of said clamping members having a similar undulation to mate with the undulation of said insert, at least one of said clamping members having an opening therein, a projection on said isnert means and disposed in the opening to resist relative longitudinal movement between the clamping members and said insert means, the longitudinal end portions of said insert means projecting beyond the corresponding ends of said clamping members, said projecting end portions being tapered in a vertical direction toward the extremity of said end portions.
