ABSTRACT:
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 (13) of this invention provides a high degree of system reliability, relative to hydraulic leaks, and shields a high-pressure hose thereof (14) against damage and heat conduction to hydraulic fluid therein. The hose assembly (13) comprises a flexible high-pressure hose (14), an impervious flexible jacket (17) surrounding the hose in out-of-contact relationship therewith to define a fluid chamber (18) therebetween, and a mounting assembly (22) for mounting the hose (14) and the jacket (17) on a support member (23) to maintain them in out-of-contact relationship relative to each other. The mounting assembly (22) includes a first mount (26) for securing the hose on the support member (23) under a predetermined first sealing pressure, and a second mount (34) for securing the jacket (17) about the hose and on the support member (23) under a predetermined second sealing pressure that is less than the first sealing pressure. Method steps are taught for assembling the hose assembly (13) in this manner.
