<p>Hydraulic Hose Assembly and Method High-pressure hydraulic hoses are employed in hydrostatic drive systems to interconnect the transmission and motors thereof. It is imperative that fluid leakage be held to A minimum, or preferably eliminated, particularly where a vehicle employing the drive system is operated in a high-temperature environment, such as a foundry. The hose assembly of this invention provides a high degree of system reliability, relative to hydraulic leaks, and shields a high-pressure hose thereof against damage and heat conduction to hydraulic fluid therein. The hose assembly comprises a flexible high-pressure hose, an impervious flexible jacket surrounding the hose in out-of-contact relationship therewith to define a fluid chamber therebetween, and a mounting assembly for mounting the hose and the jacket on a support member to maintain them in out-of-contact relationship relative to each other. The mounting assembly includes a first mount for securing the hose on the support member under a predetermined first sealing pressure, and a second mount for securing the jacket about the hose and on the support member under a predetermined second sealing pressure that is less than the first sealing pressure. Method steps are taught for assembling the hose assembly in this manner.</p> |
