The invention relates to a height valve adjusting rod, and relates to the technical field of railway vehicles, the height valve adjusting rod comprises a first rod body, a second rod body and a nut, the first rod body and the second rod body are located on the two sides of the nut and are connected into a whole through the nut, a first arc transition structure and a second arc transition structure are arranged on the sides, close to the nut, of the first rod body and the second rod body respectively. Contact points of the first rod body and the second rod body and the nut are connected through the first arc transition structure and the second arc transition structure, stress concentration in a high-stress area is effectively reduced, and therefore the occurrence risk of fatigue cracks is reduced, the arc transition structures can effectively delay the expansion speed of the fatigue cracks, and the service life of the nut is prolonged. Therefore, the service life of the height valve adjusting rod can be obviously prolonged; by designing a reasonable arc transition structure, the stress distribution of the material can be improved, and the overall fatigue strength is improved, which is particularly important for the height valve adjusting rod which needs to bear vibration and deformation for a long time.
本申请涉及一种高度阀调节杆,其涉及轨道车辆技术的领域,其包括第一杆体、第二杆体与螺母,所述第一杆体与所述第二杆体位于所述螺母的两侧并通过所述螺母连接成一体,所述第一杆体与所述第二杆体靠近所述螺母的一侧分别设为第一圆弧过渡结构与第二圆弧过渡结构。本申请通过第一圆弧过渡结构和第二圆弧过渡结构连接第一杆体和第二杆体与螺母的接触点,有效减少在高应力区域的应力集中,从而降低疲劳裂纹的发生风险,圆弧过渡结构还能够有效延缓疲劳裂纹的扩展速度,因此能够显著提升高度阀调节杆的使用寿命;通过设计合理的圆弧过渡结构,可以改善材料的应力分布,提高整体的疲劳强度,这对于需要长期承受振动和变形的高度阀调节杆尤为重要。
