Automobile emergency steering system

Abstract

The embodiment of the invention provides an automobile emergency steering system which comprises four steering oil cylinders, an auxiliary pump, an oil return filter, a steering multi-way valve, a steering valve set, a flow amplifier, a steering limiting valve set, two shuttle valves, a steering gear, an emergency steering valve set, an energy accumulator set, a radiator, a cooling auxiliary pump and a pressure oil filter. A variable pump, an oil suction filter and related pipelines; and a steering butterfly plate. According to the automobile emergency steering system, energy stored in the battery pack serves as motor input to drive the main pump and the auxiliary pump to work, under the condition of power failure of the whole system, emergency steering of a failed automobile can be achieved, and the system reliability is high.

Description

technical field [0001] The embodiments of the present application relate to the application field of engineering machinery, and in particular to an automobile emergency steering system. Background technique [0002] With the continuous increase of global resource consumption, energy conservation and emission reduction has become an important strategy. The technology of new energy vehicles is constantly improving, and the same is true in the field of construction machinery. Heavy-duty frame vehicles used for material transportation in the metallurgical industry have begun to use new hybrid technologies. [0003] Power is supplied to the motor through the battery pack to complete walking, turning and other actions, and then complete material transportation. The proportion of the power system in the new frame vehicle is getting higher and higher. Once the power system fails, the whole vehicle will stop working, which poses a high safety hazard to the vehicle in motion. A system...

AI Technical Summary

Problems solved by technology

[0004] At present, the emergency steering system needs the emergency auxiliary pump as the power source input, and the emergency auxiliary pump needs to be driven by the motor or the engine, which limits the scope of application and cannot cope with the failure of the power source.

For example, in the prior art, the emergency steering system mainly has two methods, one is to judge the vehicle state through the driver’s manual operation, which relies on the driver’s work experience, and has potential safety hazards; the other is to automatically judge through the complex sensor network The current steering state is automatically adjusted, but there are disadvantages such as high price and insufficient reliability
