The invention relates to the technical field of automobile hydraulic power-assisted steering, in particular to a hydraulic power-assisted steering oil tank and a hydraulic power-assisted steering system.The hydraulic power-assisted steering oil tank comprises a lower shell, an upper shell fixedly arranged on the lower shell and a liquid adding cover detachably connected to a liquid adding opening in the top of the upper shell. A filter element is arranged in an inner cavity of the lower shell, an annular cavity is formed between the outer side of the filter element and the inner side wall of the lower shell, a partition plate assembly is arranged in the annular cavity, and a gap is formed between the partition plate assembly and the filter element. The partition plate assembly is integrally arranged in the annular cavity of the lower shell, when rotationally flowing hydraulic oil encounters the partition plate assembly, certain resistance can be encountered, correspondingly, the rotating speed of the hydraulic oil can be gradually reduced, vortex can be effectively prevented from being generated, then vortex can be prevented from being generated in the oil tank during oil return, and the service life of the oil tank is prolonged. The problem of steering failure or steering difficulty caused by the fact that gas enters a steering system along with the vortex is avoided, and the reliability of the whole vehicle is improved.
本发明涉及汽车液压助力转向技术领域,尤其涉及一种液压助力的转向油罐及液压助力转向系统,包括下壳体、固定设置于下壳体上的上壳体以及可拆卸连接于上壳体顶部的加液口处的加液盖体。下壳体的内腔设置有过滤芯,且过滤芯外侧与下壳体内侧壁之间形成环形腔室,环形腔室内设置有隔板组件,且隔板组件与过滤芯之间具有间隙。通过在下壳体的环形腔室内一体化设置隔板组件,当旋转流动的液压油遇到隔板组件时便会遇到一定的阻力,相应地液压油的转速便会逐渐降低,能够有效的防止旋涡的产生,进而能够防止回油时油罐的内部产生旋涡,避免了气体随旋涡进入转向系统内造成转向失灵或转向困难的问题,提高了整车的可靠性能。
