    • The fiberglass reinforced plastics bumper reinforcement fitted with an elastic bumper--which is laterally mounted to the vehicle and which consists, in cross section, of a plurality of rectangular frames stacked in layer--is characterized by forwardly projecting strips formed at the intersections between the front wall of the bumper reinforcement and the top and bottom plates of the reinforcement as well as the horizontally extending webs. These projecting strips on the front wall of the bumper reinforcement alleviate the stress concentrations at these intersections that might be caused when an impact load is applied to the elastic bumper and therefore the bumper reinforcement, thus increasing the fracture strength of the intersections of the bumper reinforcement. The bumper reinforcement is further characterized in that at least one of the top and bottom projecting strips is provided with a protrusion raised upward or downward from the outer surface of the top or bottom plate to further reduce the stress concentration at the intersections.
    • 装配有弹性保险杠的玻璃纤维增​​强塑料保险杠加强件,其横向地安装在车辆上,并且在横截面上由层叠的多个矩形框架组成,其特征在于前部突出的条形成在前部 保险杠加强件的壁和加强件的顶板和底板以及水平延伸的腹板。 保险杠加强件前壁上的这些突出条有助于减轻这些交点处的应力集中,这些冲击负荷施加在弹性保险杠上并因此增加了保险杠加强件,从而增加了保险杠加强件的交叉点的断裂强度 。 保险杠加强件的特征还在于,顶部和底部突出条中的至少一个设置有从顶板或底板的外表面向上或向下凸起的突起,以进一步减小交叉点处的应力集中。

    • A leaf spring assembly comprises a longitudinal leaf spring of fiber reinforced plastics having a first surface to be applied with a tension force and a second surface to be applied with a compression force, a pair of retainer plates attached to the first and second surfaces of the leaf spring, and a pair of U-bolts and nuts for clamping the retainer plates to the leaf spring and mounting the same on an axle housing. The leaf spring is provided at the second surface thereof with a recess which is located substantially at the central portion of the leaf spring. The leaf spring assembly further comprises a seat plate formed with a protruded portion coupled with the recess of the leaf spring and secured to the second surface of the leaf spring, and a position pin fixed to the retainer plate attached to the second surface of the leaf spring, the position pin being coupled with the recess of the leaf spring through the seat plate to position the retainer plates substantially at the central portion of the leaf spring.
    • 一种板簧组件包括一个纤维增强塑料的纵向板簧,具有一个要施加张力的第一表面和一个施加有压力的第二表面,一对固定板连接到第一和第二表面上 板簧,以及一对U形螺栓和螺母,用于将保持板夹紧到板簧上并将其安装在轴壳体上。 板簧在其第二表面处设置有基本上位于板簧的中心部分处的凹部。 板簧组件还包括一个座板,该座板形成有与片簧的凹部联接的突出部分并且固定到板簧的第二表面,以及固定到固定板的位置销,该定位销附接到叶片的第二表面 弹簧,位置销通过座板与片簧的凹部联接,以将保持板基本上定位在板簧的中心部分。
