Abstract
PURPOSE:To provide an FRP leaf spring which is not requred of working accompanied by the cutting-off of embedded fibrous material and can be positioned in the assembly and installation of an overlapped leaf spring unit and be protected from displacement. CONSTITUTION:The overlapped leaf spring unit 1 comprises a major leaf spring 2 and a minor leaf spring 3 which are made from FRP and overlapped with each other. Both the leaf springs 2, 3 are tightened between an axle 4 and a clamping plate 5 by U-bolts 6 and nuts 7. Projections 10 extend from the central parts of the leaf springs 2, 3 in the direction of the thickness. The axle 4 and the clamping plate 5 are provided with positioning recesses 11 fetted with the projections 10. The projections can be made by implanting pins 12 in the leaf springs, winding a prepreg tape or the like on the pins, shaping the tape under pressure together with the leaf springs and hardening them under heat.
