Definitions
- a railway vehicle truck has a frame comprising a pair of transversely spaced, longitudinally extending transoms and a transversely extending transom pivoted at its ends to the midpoint of at least one of the side frames.
- the side frame is connected to the transom by a longitudinally extending anchor link spaced transversely of the truck from the pivotal connection.
- a transverse load supporting bolster overlies the transom and may be spring supported on the side frames, or may be swivelly supported on the truck frame and mount springs at its ends for direct support of a car body.
- the transom is pivotally connected to both side frames, and in another embodiment the transom is rigid with one side frame and pivotally connected to the other.
- the invention relates to railway rolling stock and consists particularly in a railway vehicle truck having a positively trammed multipiece frame.
- Prior Art trucks of the type having separate relatively movable side frames connected by a transverse transom pivotally secured at its ends to each of the side frames have generally relied on an elongated pivot member and bearing for retaining the side frames in tram, i.e., in right-angle relation, with the transom and in parallelism with each other. Examples of this construction are shown in R. L. Lich US. Pat. No. 2,913,998.
- the invention provides a simple lightweight truck of the separate relatively movable side frame type having positive tramming means.
- Positive tramming is provided by connecting at least one of the transom ends to the middle of one of "he side frames by a spherical pivot and connecting the side frame to the transom by a longitudinal anchor or radius rod spaced transversely of the truck from the spherical pivot.
- FIG. 1 is a plan view of a truck embodying the invention, partially sectionalized along line 11 of FIG. 3.
- FIG. 2 is a side elevational view of the truck illustrated in FIG. 1.
- FIG. 3 is a transverse vertical sectional view of the truck illustrated in FIGS. 1 and 2, taken along line 3-3 of FIG. 1.
- FIG. 4 is a plan view of a modified form of the truck illustrated in FIGS. 1-3.
- FIG. 5 is a side elevational view of the truck illustrated in FIG. 4.
- FIG. 6 is a transverse vertical sectional view of the truck illustrated in FIGS. 4 and 5, taken along line 66 of FIG. 4.
- the truck includes gauged pairs of flanged railway wheels 1 mounted on the ends of longitudinally spaced axles 3. Inboard of wheels 1, axles 3 are rotatably received within journal boxes 5 and longitudinally extending side frames 7 are clamped at their ends to journal boxes 5, an elastomeric grommet or ring 9 being interposed between the side frame and journal box interfaces.
- each side frame is formed with a cylindrical aperture 11 in which is positioned an elastomerically brushed spherical pivot comprising an outer ball socket annulus 13, a ball 15, an elastomeric bushing 17 interposed between annulus 13 and ball 15 to permit universal movements of the ball with respect to the annulus through shear in bushing 17 and thereby eliminate me tal-to-metal friction and consequent wear.
- Annulus 13 is tightly seated in aperture 11, against an annular shoulder 18, and ball 15 is secured by means of bolt 19 to the end of a cylindrical projection 20 on the end of box section transom 21 which thereby ties side frames 7 to each other and permits their relative pivotal movement about the common transverse axes of ball 15.
- This arrangement also permits relative pivotal movements of transom 29 about the longitudinal axes of the side frames to accommodate differences in height between the opposide track tails without requiring tipping of the side frames about their longitudinal axes.
- each of side frames 7 is formed with an inboard transversely extending plate-like bracket 23 preferably at or near the same level as the common transverse axis of balls 15 and an anchor link 25, which may be of the type disclosed in Vernon Greene Reissue US. Pat. No. 2l,987, is pivotally connected at its one end to bracket 23 and at its other end to the remote side wall 27 (on the left side) or 29 (on the right side) of transom 21, the adjacent side wall 29 (on the left side) or 27 (on the right side of the truck) of transom 21 being apertured at 31 to permit the passage therethrough of anchor link 25.
- a flat horizontal elastomeric sandwich comprising an elastomeric pad 35 bounded on the top and bottom by metal plates is seated on top of each side frame intermediate the axles and in alignment with the support of the side frame on the axles, and is held against longitudinal and transverse movement thereon by upstanding ribs 37 and 39 on the top of each side frame.
- An upwardly facing spring seat 41 formed with corresponding depending ribs 43 and 45 is seated on each sandwich and mounts an upstanding coil spring 47.
- a transverse bolster 49 of inverted channel cross section is supported on top of springs 47 and is formed with depending rims 51 surrounding the tops of springs 47 and holding them against transverse or longitudinal movement with respect to bolster 49.
- each side frame is formed with an upstanding and transversely outwardly extending bracket 51, to which is pivotally connected one end of a longitudinally extending bolster anchor link 53, which may also be of the type disclosed in the previously mentioned Vernon Green Reissue US. Pat. No. 21,987.
- Bolster 49 is formed at its ends with depending brackets 55, to which are pivotally secured the opposite ends of anchor links 53, so that bolster 49 is free to move vertically on coil spring 47 and transversely through shear in pads 35, but is restrained against movement longitudinally with respect to side frames 7 by anchor links 53.
- transom 21 For limiting transverse movements of bolster 49 relative to side frames 7 and transom 21, the center portion of transom 21 is formed with a pair of transversely spaced vertical walls 57 extending longitudinally of the truck and bolster 49 is formed with a pair of depending brackets 59, the lower ends of which extend into the end portions of transom 21 and are spaced respectively transversely outwardly from transom walls 57.
- Elastomeric bumpers 61 are mounted on the inboard faces of brackets 59 in spaced relation to walls 57 so as to engage walls 57 during transverse movements of the bolster and thereby resiliently limit such movements.
- top surface bolster 49 On its top surface bolster 49 is formed at its center with a load supporting swivel central bearing element 63, on which is seated a mating body central bearing element 65, mounted on the vehicle body bolster B.
- Normally vertically spaced stop elements 67 and 69 are provided on top of truck bolster 49 and on the bottom of body bolster B to limit tipping of the body on the truck in the event of the application of excessive lateral forces to the body.
- motor and gear box support brackets 71 and 73 may also be formed respectively on side frame 7 and on upstanding bracket 51 thereof, and traction motors M and gear boxes G may be resiliently supported on them in known manners.
- FIGS. 4-6 differs from that of FIGS. 1-3 in that one of the side frames 7 (at the top of FIG. 4 and on the right side of FIG. 6) is formed with an integral transom 21 extending rigidly from the central region of side frame 7 toward the other side frame 7, and connected to the latter by a pivotal connection 13, 15, 17 and by a longitudinal link 25, as described in connection with the embodiment of FIGS. 1-3.
- transom 21 This rigid connection of transom 21 to side frame 7 stabilizes transom 21 against substantial tipping about the transverse axis of the truck and thereby makes it possible to support traction motors and drive equipment from transom 21'.
- motor support brackets 61 are formed on each side of transom 21 and may each have a horizontal shelf 63 supporting a depending vertical anchor link for supporting a motor bracket B extending from the adjacent motor toward transom 21' and underlying shelf 63.
- a railway vehicle truck comprising a pair of spaced axles, a gauged pair of wheels mounted on the ends of each said axle, longitudinally extending transversely spaced side frames supported at their ends on opposite end portions of said axles, a transverse transom extending the full distance between said side frames, means preventing relative vertical and lateral movement and relative angular movement in the horizontal plane between said transom and both said side frames, said preventing means including a pivotal connection between one of said side frames and said transom intermediate said axles and in substantial longitudinal alignment with the supports of said one side frame on said axles, permitting pivotal movement of said one side frame about a transverse axis with respect to said transom, and longitudinally extending link means spaced inwardly transversely of the truck from said pivotal connection and being pivotally connected at its one end to said one side frame and at its other end to said transom.
- a railway vehicle truck according to claim 3 wherein said transom has side walls spaced apart longitudinally of the truck and extending generally transversely of the truck, said link means passing through an aperture in one of said side walls and being pivotally connected to said other side wall.
- a railway vehicle truck according to claim 3 including an inboard bracket on a side frame adjacent said one side wall of said transom, said link means being pivotally connected to one of said brackets.
- a railway vehicle truck according to claim 1 wherein said pivotal connecting means is constructed to permit pivotal movements of said transom about the longitudinal axes of the side frame to which it is pivotally connected.
- said pivotal connecting means comprises a ball and socket, said socket being mounted on the associated side frame and said ball being secured to an end of said transom.
- a railway vehicle truck including upright spring devices seated on said side frames intermediate their ends, a transverse bolster carried on said spring devices, means holding said bolster against movement longitudinally of the truck with respect to said side frames while accommodating other movements of said bolster permitted by said upright springs.
