High Pressure Piping of Tractive Transport Vehicles

In order to protect a hydraulic actuator of the ground tractive transport vehicles from the unauthorized ejection of working liquid into the atmosphere in case of breaking high pressure piping under the existing condition of hydraulic system of tractive transport vehicles was analyzed, reasons of high pressure hoses breaking were found out, and technical solution of how to eliminate the mentioned drawback was developed. To avoid breaking of flexible high pressure hose, the authors proposed to protect with a strong sealed shell filled under pressure with gas (air or inert gas), providing reduction of after-effects of cyclic loads on the hose and, as a result, providing increase of its resource, safety and durability. The structure of flexible high pressure piping due to back pressure from the side of the strong sealed shell improves hose properties and reduces cyclic loads on the hydraulic actuator, preventing the hose from untimely breaking and ejection of working liquid into the atmosphere. At the same time, operating expenses and contamination of the environment are reduced.
