The invention relates to a steering system comprising a hydraulic transmission unit. The steering system comprises a hydraulic transmission unit, and the hydraulic transmission unit comprises a first telescopic cylinder and a second telescopic cylinder; one end of the first telescopic cylinder is in transmission connection with the output side of the steering gear; one of the inner cavities of the two cylinder bodies of the first telescopic cylinder is communicated with one of the inner cavities of the two cylinder bodies of the second telescopic cylinder through a first intercommunication pipeline, and the other one of the inner cavities of the two cylinder bodies of the first telescopic cylinder is communicated with the other one of the inner cavities of the two cylinder bodies of the second telescopic cylinder through a second intercommunication pipeline; oil in the two telescopic cylinders is communicated with each other; each of the first intercommunication pipeline and the second intercommunication pipeline comprises a hose section; when the first telescopic cylinder stretches out and draws back, the second telescopic cylinder is driven to stretch out and draw back through hydraulic action. The steering system can adapt to the position change of the wheels through the hose sections of the intercommunication pipelines in the wheel lifting process, and the structure of the steering system is greatly simplified.
本发明涉及一种包含液压传动单元的转向系统。转向系统包括液压传动单元,液压传动单元包括第一伸缩缸及第二伸缩缸;第一伸缩缸一端与转向器的输出侧传动连接,第二伸缩缸一端与转向节臂铰接;第一伸缩缸的两个缸体内腔中的一个通过第一互通管路与第二伸缩缸的两个缸体内腔中的一个连通,第一伸缩缸的两个缸体内腔中的另一个通过第二互通管路与第二伸缩缸的两个缸体内腔中的另一个连通,以使两个伸缩缸内的油液互通;第一互通管路和第二互通管路均包含软管段;在第一伸缩缸伸缩时,通过液压作用带动第二伸缩缸伸缩。本发明的转向系统在车轮升降过程中能够通过互通管路的软管段适应车轮的位置变化,大大简化了转向系统的结构。
