ABSTRACT:
A rail car axle (1) carries on one of its ends a hydraulic pump (10) for energizing auxiliary devices. This pump has several pistons (11) driven by a wobble plate (12) carried on the end of a shaft (13). The car axle (1) is supported by bearings (2) placed inside a housing (3) and held in place by a cover (3a) attached to the axle end by bolts (4). The axle (1) is fastened to its undercarriage by an adaptor piece (48) attached to the housing (3). The body (16) of pump (10) is made of two parts, the first one comprising the bores (15) receiving the pistons (11) with the check valves (17) and the outlet (18), while the second part comprises the inlet (19) which opens into the chamber (20) inside which revolves the wobble plate (12). According to this invention, the second part of the pump body (16) comprises a central element (40) having a central bore containing the bearings (21) for the wobble plate shaft (13). Shaft (13) is splined and engages a splined sleeve (41) integral with a flange (29) held by a spring (42) against the cover (3a) of the axle bearings (2), so as to be driven by the bolts (4). This second part of the pump body (16) further comprises a skirt (43) around the central element (40). This skirt carries lugs (44) for firmly fastening the pump body (16) to the adaptor piece (48) which connects the axle (1) with its undercarriage. The lugs (44) are fastened to the adaptor piece (48) by bolts (47) passing through spacer sleeves (45).
