The invention belongs to the technical field of vehicle steering systems, and discloses a servo steering system and a dumper. The servo steering system comprises a steering device, a transmission mechanism, an execution unit and a feedback mechanism, wherein the transmission mechanism is connected with the steering device; the execution unit comprises a pilot valve, a steering valve and a steering oil cylinder, the pilot valve is connected with the transmission mechanism, the transmission mechanism can drive a valve element of the pilot valve to move so as to convey pilot oil to the steering valve, the steering valve is used for controlling the steering oil cylinder, and the steering oil cylinder is connected with a bogie of the vehicle; the execution unit has a steering state and a balance state, when the execution unit is in the steering state, the pilot valve conveys pilot oil to the steering valve so that the steering valve can control the steering oil cylinder to act to drive the bogie to rotate, and when the execution unit is in the balance state, the pilot valve stops conveying the pilot oil to the steering valve, and the steering oil cylinder stops acting. The servo steering system is simple in structure, flexible in arrangement, low in manufacturing cost and capable of improving the driving experience of a driver.

    本发明属于车辆转向系统技术领域,公开了一种伺服转向系统及自卸车。该伺服转向系统包括转向装置、传动机构、执行单元以及反馈机构,传动机构与转向装置连接;执行单元包括先导阀、转向阀以及转向油缸,先导阀与传动机构连接,传动机构能够带动先导阀的阀芯移动以向转向阀输送先导油,转向阀用于控制转向油缸,转向油缸与车辆的转向架连接;执行单元具有转向状态和平衡状态,当执行单元处于转向状态时,先导阀向转向阀输送先导油,以使转向阀控制转向油缸动作以驱动转向架转动,当执行单元处于平衡状态时,先导阀停止向转向阀输送先导油,转向油缸停止动作。该伺服转向系统结构简单、布置灵活且制造成本低,能够提升驾驶员的驾驶体验。
