摘要： A rubber spring device is formed by alternately laminating a plurality of layers of hard plates whose linear dimension W in a direction parallel to the longitudinal direction of each equalizer bar is shorter in plan view than a linear dimension H in a direction parallel to an axle direction, and rubber layers. The rubber spring device is disposed between an end portion of each equalizer bar and a center axle in an articulated dump truck, and is allowed to function as a suspension. Thus, even when the rubber spring device is deformed into an accordion shape, peak positions of an internal stress within each rubber layer can be dispersed and reduced, thereby preventing generation of cracks within each rubber layer.
摘要翻译： 橡胶弹簧装置通过交替地层叠多个硬质平板，其平行于每个均衡棒的纵向方向上的直线尺寸W在平面图中比线轴尺寸H在平行于轴方向的方向上短 ，和橡胶层。 橡胶弹簧装置设置在每个均衡棒的端部和铰接式自卸车中的中心轴之间，并被允许用作悬架。 因此，即使当橡胶弹簧装置变形为手风琴形状时，也可以分散和减少橡胶层内的内应力的峰值位置，从而防止在每个橡胶层内产生裂纹。
