SWING OUT OIL COOLER MOUNTING Filed March 4, 1965 2 Sheets-Sheet 2 is ////1"' )l INVENTORS ROBERT D. WILLIAMS EUGENE F. MIELNIKOWSKI United States Patent 3,2Q7,08t) SWING OUT OIL COOLER MGUNTJING Robert D. Williams, La Grange, and Eugene F. Mielnikowski, Chicago, llll., assignors to International Harvester Company, Chicago, 111., a corporation of New Jersey Filed Mar. 4, 1965, Ser. No. 437,077 4- Claims. ((31; 165-77) This invention relates to a hydraulic fluid cooler and more particularly to an improved hydraulic fluid cooler mounting arrangement.
Hydraulic fluid coolers such as that referred to are con ventionally included in the hydraulic systems of tractors and other vehicles utilizing hydraulic power steering or driving components, the fluid coolers being utilized to remove excessive heat from rapidly moving pressurized hydraulic fluid to maintain the hydraulic system at an optimum operating temperature for good hydraulic performance as well as for good lubrication.
Generally, the hydraulic fluid cooler, or oil cooler as it is more commonly referred to, is mounted on an associated vehicle directly in front of the vehicle radiator where circulating air provided by movement of the vehicle as well as by a radiator fan, not shown, helps to carry away some of the heat from the oil cooler coils to the surrounding atmosphere. Unfortunately, this arrangement usually requires complete demounting of the oil cooler and disassembly of the associated oil cooler lines in order to remove chafl or other debris which lodges between the radiator and the oil cooler and to clean the front surface of the radiator core.
Accordingly, it is an object of the present invention to provide an improved hydraulic fluid cooler mounting arrangement.
It is another object of the invention to provide an hydraulic fluid cooler mounting arrangement whereby the cooler may be readily moved out of its normal operating position in front of the engine radiator to permit cleaning of the space between the cooler and the radiator without demounting the cooler from the radiator housing or disconnecting associated hydraulic fluid lines or materially altering the radiator structure and its mounting.
Still another object of the invention is to provide an hydraulic fluid cooler mounting arrangement whereby the cooler can be swung quickly out of operating position into a cleaning position in which the radiator is exposed for cleaning the front surface of the engine radiator core and to remove chaff which has lodged between the oil cooler and the radiator.
Yet another object of the invention is to provide a mounting arrangement for a hydraulic fluid cooler which permits movement of the cooler swingingly away from the radiator to permit cleaning of the radiator, the cooler being held securely in operating position parallel to the radiator at other times.
These and other objects of the invention will become clear from the following disclosure when considered in conjunction with the appended claims and accompanying drawings, wherein:
FIG. 1 is a front elevational view of a hydraulic fluid cooler mounted in accordance with the principles of the present invention in front of an associated tractor engine radiator with an associated hydraulic system shown schematically;
FIG. 2 is a front elevational perspective view on an englarged scale of the cooler mounting arrangement illustrated in FIG. 1 with the cooler swung outwardly from its operating position;
FIGS. 3 and 4 are front elevational views on an enlarged scale of portions of the mounting arrangement illustrated in FIG. 1, showing details of the mounting arrangement and the manner in which the hydraulic fluid connections are made to the oil cooler;
FIG. 5 is a right side elevational view of a lower portion of the cooler arrangement shown in FIG. 1;
FIG. 6 is a fragmentary plan View in section 011 an enlarged scale of a holding means provided to maintain the cooler in operating position parallel to the radiator with a cleaning position of the holding means being shown in broken line superimposed on the figure.
Referring in greater detail to the drawings, FIGS. 1 and 2 show a hydraulic fluid or oil cooler 10 mounted within a radiator housing 12 mounted on the supporting frame 13 of an associated vehicle, not shown, the oil cooler being positioned in front of a radiator 14 in an operating position generally parallel to the radiator.
The oil cooler 10 is part of a hydraulic fluid system shown schematically in FIG. 1 including a source of hydraulic fluid under pressure to be cooled shown generally by the numeral 15, and a hydraulic fluid reservoir 17. An inlet cooler line 16 and an outlet cooler line 18 are provided comprising lengths of flexible hose or elastomeric couplings formed of synthetic rubber or the like, lines 16, 18 communicatively connecting the cooler respectively to the source of fluid to be cooled and to a hydraulic fluid exhaust line 20 downstream from the oil cooler and leading to the hydraulic fluid reservoir. A conventional fluid leakage in line 22 is provided communicatively connecting an associated hydraulic steering system outlet 23 to the exhaust line 20.
The cooler 10 includes a cooler frame 24, FIG. 2, having generally upright left and right spaced frame ends 26, 28, upper and lower frame portions 30, 32 and a plate like side portion 34 secured fixedly to the left frame end 26. The plate like side portion 34 extends over a left portion of the housing 12 as viewed in FIGS. 1, 2 and has locking or holding means 36 thereon maintaining the oil cooler in operating position parallel to the radiator.
The oil cooler 10 includes a generally horizontally extending coil 37 comprising a plurality of vertically spaced lengths of tubing 38 communicatively connected at their ends in zig zag fashion and extending through the left and right frame ends 26, 28. A plurality of vertically extending cooling fins designated generally by the numeral 40, FIGS. 3, 4 are secured in position generally trans verse the lengths of tubing 38 for transfer of heat from the coil tubing 38 carrying hydraulic fluid to be cooled to the surrounding atmosphere.
Referring now to FIGS. 3, 4 the coil 37 has an inlet end 42 comprising a piece of piping communicatively connected to the tubing 38 and extending generally upwardly and toward an upper extension, not shown, of the left frame end of the cooler, the inlet end 42 being connected communicatively to the source of fluid to be cooled by inlet line or coupling 16 which is secured conventionally about the inlet end 42 by clamp 44, FIG. 2, the coupling 16 having sufficient flexibility to permit the cooler to be swung radially outwardly about about a vertical axis of rotation at the right end of the cooler.
A downwardly extending cooler outlet opening or pipe 45 is connected communicatively by outlet cooler line 18 to an upright pipe portion 46 of a T connection 48 which is connected to exhaust line 20 and leakage line 22, the T connection 48 being secured in position about the pipes 45, 46 by conventional clamps 51, 5'2, FIG. 2.
The oil cooler it) is mounted for pivotal movement outwardly about a center of rotation comprising a vertical axis at the right frame end 28 of the cooler by hinged connections 54 of the pin type connecting the right frame end 28 of the cooler and the radiator housing 12 and secured thereto as by welding or bolting. The hinged connections 54 permit the cooler to be swung pivotally =31 outwardly from the radiator as illustrated in FIG. 2 through an arc of about 90 providing accessibility to the front surface of the engine radiator for cleaning purposes.
Locking or holding means 36 provided for maintaining the cooler in the operating position illustrated in FIG. 1 comprises a pair of friction fasteners 56, FIG. 6, each having a plurality of prongs or fingers 58 extending generally horizontally inwardly from the plate-like side portion 34 and cantilevered from the side portion 26 toward the radiator and radiator housing and adapted to be received frictionally in radiator frame openings 60 in line with the prongs. The frame openings 60 have serrated or notched inner surfaces 62 which are adapted to catch laterally or radially protruding portions 64 of the prongs 58. The prongs 58 are adapted to be compressed radially inwardly within the openings 60 between the serrated surfaces 62 toward a fastener center line 66 between the prongs 58 of each friction fastener so as to frictionally hug the inner serrated surfaces of the openings and thus to maintain the cooler in operating position generally parallel to the radiator. When it is desired to clean the front surface of the radiator or the space between the oil cooler and the radiator, it is a simple matter to pull the pronged friction fasteners from their openings by merely grasping the cooler and pulling outwardly, the prongs at this time being compressed radially inwardly to permit the cooler to swing out.
Having now described the invention its operation should be clear. Since modifications of the details of the structure as illustrated in the various figures are contemplated, the invention should be limited only by the scope of the appended claims.
