Abstract

The invention relates to the technical field of vehicle emergency steering, and provides a vehicle emergency steering hydraulic system and an operation vehicle. The vehicle emergency steering hydraulic system comprises a steering loop, a steering gear and an emergency steering loop, the steering gear is arranged on the steering loop and the emergency steering loop, and the steering gear is used for controlling the steering direction of a vehicle; when a vehicle engine works, the steering loop and the emergency steering loop are in a conducting state; and when the vehicle engine stops working, the steering loop is in an off state, and the emergency steering loop is in an on state. The problems that in the prior art, heating is caused by idle running of an emergency steering loop of emergency power during normal running of an operation vehicle, and faults are difficult to find are solved. According to the vehicle emergency steering hydraulic system, when the vehicle runs normally, the emergency steering loop participates in work, the heating value is reduced, when the emergency steering loop breaks down, the fault of the emergency steering loop can be found in time, and safe running of the vehicle is guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicle emergency steering, in particular to a vehicle emergency steering hydraulic system and a working vehicle. Background technique [0002] If the work vehicle encounters an emergency while driving normally, the power of the vehicle will fail, and the engine will stop or turn off. At this time, the hydraulic power steering device will lose its power source, and it will be difficult for the driver to turn the steering wheel to achieve steering, which will easily lead to accidents. Therefore, it is necessary to increase emergency power in the steering system of the work vehicle to drive the hydraulic power assist device to realize emergency steering. [0003] In the existing work vehicle steering system, the emergency power is in an idling state when the work vehicle is running normally, which increases the energy consumption and heat generation of the steering system, and it is difficult to find out in...
