The invention provides a self-repairing steering pull rod. The self-repairing steering pull rod comprises a self-repairing pull rod assembly, the self-repairing pull rod assembly sequentially comprises an inner supporting pipe, an inner supporting pipe shell, a self-repairing layer and an outer protecting pipe from inside to outside, and the self-repairing layer is formed by foaming a self-repairing material. The innovative self-repairing pull rod assembly is adopted as a main material and has excellent compression resistance and shock resistance and low thermal conductivity, so that the use effect of the self-repairing pull rod assembly is not prone to being affected by vibration and temperature changes; certain self-repairing performance is achieved, the service life of the steering pullrod is remarkably prolonged, and the overhauling and replacing frequency is reduced; and on the basis of slightly increasing the material cost, the use strength is greatly improved, and the materialis suitable for popularization and has good market prospects.
本发明提供一种自修复式转向拉杆,该转向拉杆包含有自修复拉杆合件;自修复拉杆合件由内至外依次包括内支撑管、内支撑管壳、自修复层以及外护管;自修复层由自修复材料发泡而成。本发明采用创新性的自修复拉杆合件作为主材料,具有优秀的防压抗震性能以及较低的热传导率,使其不易因震动以及温度的变化影响到使用效果;具有一定的自修复性能,显著延长转向拉杆的使用寿命,降低检修以及更换频率;在稍微提升材料成本的基础上,大大提升了使用强度,适于推广,具有良好的市场前景。
