.The `fixing vof the frame toY the housing is con- "venently yeffected `by resting one -side of 'the :frame-on nger-like projections on the housing,

`the other fsidefbeing mounted indirectly on lugs in the f :housing f with packing pieces :interposed 'Thiswiadmits of fthe bottom-shel1 rbeing tted ffinfplacein a very simplemannereven when the axle yj ournal r isi provided with `a'fi--xedi l end4 flange vor shroud. --The'ngerl-ike lugs on thehousing are preferably arranged at a level differingyf'romn that of the lugs by the thickness of the packing piece, which thickness is at least equal to the depth of the axle journal end shroud. Thus, by tilting the bottom shell and the frame, both of these members can be introduced past the said end shroud and the frame hung on the finger-like lugs in the housing. The bottom shell and the frame are then brought up to the horizontal, whereupon the packing piece is inserted between the frame and the lugs on the housing and there secured, as, for instance, by connecting it to a part of the frame. Conversely, it is possible to disassemble in an equally simple manner.

There may also be provided, in the housing, ribs, which receive the bottom shell between them and so secure it against axial displacement. 'I'he frame is then flxedly attached `to the lugs on the housing which carry it so that when the bearing is assembled there is no possibility of any axial displacement at all. In order to ensure that, in the case of axle bearings which are stressed to an unusually high degree, shocks which reach the bottom shell shall be transmitted directly, in the direction of impact, to the housing of the bearing, the frame may be provided with an attachment in the form of a lubricant reservoir, by means of which attachment it is supported in midposition relatively to the housing, preferably against longitudinal ribs thereon. In this case it is advantageous to lock the frame against axial displacement by attaching the aforesaid extension to the housing more particularly to a transverse rib on the same.

In bottom shells whereof the middle part lies between the frame members locking against axial displacement is preferably effected by means of ribs provided in the housing, against which ribs the bowed arms of the frame bear on both sides, so as to lock the said frame and the bottom shell axially. The bottom shell then preferably extends into the space between the ribs on the housing. This makes it possible to augment the working of the bottom shell in the capacity of a lubricant catching member, it being immaterial whether the bottom shell picks up oil delivered solely for this purpose to a point above such bottom shell or whether said bottom shell merely carries off from the surface of the axle journal such lubricant as has not been used up in lubricating said journal by means of the upper liner shell and is flowing back to the lubricant reservoir.

In the accompanying drawings which illustrate practical embodiments of the idea according to the invention:

Figs. l and 2 are longitudinal and transverse sections through an axle bearing, showing one constructional embodiment of the same wherein the middle part of the bottom shell rests in a hollow on the frame. More particularly the left hand half of Fig. 2 is a section taken on line A-A of Fig. 1 and the right-hand half a section on line B-B thereof, while Fig. 1 is a longitudinal section on line C-C of Fig. 2.

Figs. 3 and 4 show an arrangement of the bottom shell wherein this latter is arranged wholly between the axle journal and the frame. More particularly, Fig. 3 is a vertical longitudinal section through the bearing on line D-D of Fig. 4, while Fig. 4, as regards its left-hand half is a vertical transverse section through the axle bearing, taken on line E-E of Fig. 3, while its right-hand half is a vertical section on line F-F of Fig. 3 with the bottom shell shown in end elevation.

Referring firstly to Figs. 1 and 2, the numeral l denotes the axle journal and 2 the end iiange or' shroud of said journal, which is mounted between a top shell 3 and a bottom shell 4. According to the invention this bottom shell, which preferably has an insert 5 of bearing metal, is suspended in; a frame, which is connected directly to the housing 6. This frame consists of two transverse arms 'I and 8 united, to form the frame, by means of two longitudinal bearers 9 and I0. Between the bottom shell 4 and the longitudinal bearers 9 and IIJ the devices for automatically adjusting the bottom shell consisting, in the embodiment shown in Figs. 1 and 2 of short, powerful spiral springs II, seated at one end in spring boxes I2 in the bearers 9 and I0 and, at the other end, in spring boxes I3 in the bottom shell. It is a further feature of the invention that the direct xing of the frame "I, 8, 9, I0 to the housing is effected by the frame arms 'I and 8 resting at one end directly on finger-like projections I4 on the housing while at the other end they are supported indirectly on lugs I6 on the housing, through the intermediary of packing pieces I5. As is shown particularly in Fig. l the bow-shaped arms of the frame are so disposed as to be separated only by a predetermined shock absorbing path Il' from the surface of the axle journal. Shocks occurring as between the axle journal and the housing of the axle bearing are, therefore rst imparted,V

with a certain amount of damping, to the bottom shell 4 and then, after the shock absorbing path il has been traversed, directly to the frame members 'I and 8 and by way of the parts I4 and I5, to the housing 6. The arrangement of these parts, as well as their appropriate formation makes it possible for the forces to be transmitted in this way without entailing the disadvantages which apply to the arrangement heretofore proposed. In order that the frame l, 8, 9, I Il may also be secured in the axial direction, ribs I8 and I 9 are provided in the housing and the bowed arms I and 8 of the frame bear against these ribs on both sides so as to lock the frame and the bottom shell axially. If the packing piece I5 be fastened to the bowed arm 1, as, for instance by a split pin ZIP, which affords a particularly accessible type of fixing, said packing piece will also be properly located. The bottom shell 4 preferably has pan-shaped outriggers or side wings 2I which extend into the space 22 between the ribs I8 and I9 of the housing and serve to augment the lubricant catching effect which takes place especially in the vicinity of the edges 23 of the axle box.

The new method of fixing the bottom shell makes it extremely simple to disassemble and reassemble the whole bearing. For instance, if the packing piece I5 be removed, after drawing the split pin 29, the frame and the bottom shell can be shifted axially and this releases the connection between the frame arms 'I and 8 and the finger-like projections I4 of the housing. The frame and the bottom shell can thus be brought into an inclined position and drawn, past the axle journal shroud, out of the housing of the axle bearing. As may be supposed, assembly is carried out very simply, in the reverse order.

In the constructional example illustrated in Figs. 3 and 4 the numeral I again designates the axle journal and 2 the xed shroud of the same while 3 and 4 denote the top and bottom shells in which it is carried, the bottom shell preferably including a white metal lining 5. The frame which carries the bottom shell again consists of lOl are particularly simple.

`two transverse bowsf'l ands tiedtogether tov'make lbottom'shell.

receive the frame 1-I Il and then the frame itself isi'itted in. Naturally, the same operations are carried out in reversed order when taking out the two parts. the frame I-III are arranged the springs I I used for purposes of automatic adjustment, The botl'tom shell itself is slotted at '34and in the slots are received ybars 24 which are pressed into engagement by means of the adjusting springs II and are provided with U-shaped positioning stirrups 25. If, for instance the parts have to be taken out, the locked screws 26, which fix the frame 'I-I to the lugs I5 on the housing, on which it rests, are rst released; then, by pulling down the stirrups 25, the springs II are sufciently compressed to permit the frame 'I-IIJ to be drawn out through the recesses 22 in the housing. The bottom shell then falls of its own accord into the position in which it also can be withdrawn, past the shroud of the axle journal by a simple axial movement. When assembling, the bottom shell' 4 is first introduced by way of the frecesses 22 in the housing and then the frame A"1 -Ill. with the springs II compressed', is pushed When the springs II expand the bars 24, under their influence, enter the slot-like recesses 23 in the bottom shell 4 and in this way the said bottom shell positions itself automatically.

Shocks set up as between the axle journal I and the housing 6 are imparted first to the bottom shell 4. Owing to the fact that this latter is arranged wholly between the axle journal I and the frame 'I-I and is separated from the frame solely by a predetermined and permissible shock absorbing path, the shocks, after a certain amount of damping while traversing the shock labsorbing path, are transferred to the fixed frame, through which they are carried directly to the housing' 6, or part I 6 thereof. In order that the shocks may be taken up in the actualdirection of impact, the frame 'I-Ill can, as shown in dot and dash lines in Fig. 4, beprovided with an attachment '2l in the form of a lubricant reservoir, or sump, by means of which attachment it is supported from the housing; to this end it is preferably guided, after the fashion of a slide, in corresponding recesses 28 in the longitudinal ribs 29 of the housing. In this case fixing in the axial direction is effected, not through the agency of the flangelike extension 30 ofthe frame 'I-ID and the screw 26, but with fixing means 3| which conneet the attachment 21 to a transverse rib or other fixed part of the housing 6 of the axle bearing. Since the parts II, 34, 24 and 25 are not adapted for transmitting axial thrusts from the bottom shell to the frame, ribs'or ridges 32, 3'3 are preferably provided in the housing and the bottom shell 4, more particularly, the pan-shaped outriggers 2| thereof, take in between these ribs. The pan-shaped outriggers preferably, collect the lubricant which for this purpose or in order to lubricate the axle journal, is delivered from the top shell, according to its position, on top of the Between the bottom shell 4 and In this way the outriggers provide for primary or secondary lubrication of fthe axle 1 journal.
