The invention provides a parallel shaft traction rod and a bogie, relates to the field of railway vehicle steering assemblies, and aims to solve the problem that the response speed is low due to the redundant structure of the existing traction rod, a prismatic rod body is adopted to be matched with an end, and the tension and compression resistance is improved by utilizing plane attachment of an outer winding piece to a rod body. And the reinforcements are wound at the insertion matching positions of the rod body and the end heads, so that the overall length arrangement of the annularly distributed reinforcements in the axial direction of the rod body is avoided, the weight is reduced, the response speed is increased on the basis of meeting the strength requirement, and the arrangement requirement of a narrow space where the traction rod is located is met.

    本发明提供一种平行轴牵引拉杆及转向架,涉及轨道车辆转向组件领域,针对目前牵引拉杆结构冗余导致的响应速度低的问题,采用棱柱状的杆体配合端头,利用外缠件于杆体的平面贴合提高抗拉压能力,并在杆体与端头插接配合位置缠绕加强件,避免环向分布的加强件在杆体轴向上的全长布置,满足强度需求的基础上,降低重量提高响应速度,适用于牵引拉杆所处狭窄空间的布置需求。
