Abstract

The invention provides an emergent steering system for engineering machinery. The emergent steering system comprises an oil tank, a steering pump, a gear pump, a one-way valve, a full-hydraulic steering gear, a steering oil cylinder, a three-way valve and a radiator motor. When the steering pump is broken down, the emergent steering system can communicate the gear pump with the full-hydraulic steering engine through the three-way valve to directly drive equipment to an appointed maintenance point under the condition of not using a tractor without influencing the construction of other equipment, and the equipment also can construct for a short time; and as the gear pump is only used for supplying oil to the radiator motor under the normal condition, when the steering pump is broken down, the gear pump supplies the oil to the full-hydraulic steering engine, the mode dose not increase the equipment manufacturing cost and cause the unnecessary waste, and the operation is simple.

Description

technical field [0001] The invention belongs to the field of construction machinery, and in particular relates to an emergency steering system for construction machinery. Background technique [0002] The emergency steering system in the prior art mainly considers an emergency treatment measure when the engine fails and needs to be towed away, such as adding a motor pump to assist emergency steering, or using an emergency pump to make the vehicle still have direction when it loses power and is towed away, etc. . What to do if the steering pump fails. Contents of the invention [0003] The present invention aims to overcome the defects of the prior art, and provides an emergency steering system for engineering machinery. When the steering pump fails, the gear pump can be connected with the full hydraulic steering gear through a three-way valve, and the steering system can be used without using a trailer. Drive the equipment directly to the designated maintenance point, wi...
