Definitions

  • the above-identified prior art discloses novel intermodal vehicles for use in forming a train of highway trailers including leading and trailing trailers which are interconnected to each other and supported by the intermodal vehicles.
  • the design of the intermodal vehicle of this invention, as well as the prior art referred to above, is intended for use with highway trailers of all configurations, including trailers especially designed to haul so-called "ISO" shipping containers.
  • Each of the highway trailers includes leading and trailing coupler socket assemblies at each end, each of the socket assemblies being apertured for receiving a coupling pin.
  • the intermodal vehicle is characterized by two rail wheel assemblies, lower frame means in which the rail wheel assemblies are supported, and upper lifting frame means supported on the lower frame means by spring means.
  • the spring means are air springs which are so arranged that when air is removed from the air springs, the upper lifting frame means will descend toward the lower frame means, and when air is introduced into the air springs, the upper lifting frame means will rise, at the same time raising any highway trailers which may be resting upon the load carrying surfaces.
  • the upper lifting frame means includes leading and trailing upwardly presented load carrying structures, each of the load carrying structures having an upper trailer support surface for engaging the bottom of the trailers.
  • each of the load carrying structures also carries a coupler tongue which is adapted to be received in the coupler socket assemblies, each tongue being provided with an aperture.
  • a vertically oriented coupling pin is carried by each of the load carrying structures, which coupling pin is vertically moveable from a position below the trailer support surface to a position where it passes through the apertured socket assemblies for securing a tongue within the apertured socket assembly.
  • WO 94/21503 discloses that the upper frame means may be in two sections, each independently moveable, whereas the above-identified U.S. patent discloses only a single upper frame. Whether or not a split upper frame is used, it is still essential that each tongue be supported for limited pivotal, rolling and pitching movement. It is also a feature of the above-referenced designs that the lower frame means are steerable with respect to the upper frame means.
  • the load carrying structures are shiftable transversely, that is to say, from side to side perpendicular to the longitudinal centerline of the intermodal vehicle to facilitate the alignment of the trailer as it is connected to the intermodal vehicle. Additional features are disclosed in the foregoing patent and published application.
  • each of the air springs was provided with an internal guide surmounted by a shear spring.
  • This form of design is difficult to assemble and maintain, and therefore it is proposed to use new air spring assemblies which overcome the inherent disadvantages of the prior art air springs.
  • Each of the new air spring assemblies includes a pair of external struts.
  • each of the air spring assemblies consists of a single two-convolution air spring and a single one-convolution air spring which is mounted on top of the two-convolution air spring.
  • a mounting plate is disposed above the two-convolution spring and below the one-convolution spring, the mounting plate being guided by the pair of external struts.
  • steering dampers are provided (at 96 in FIG. 3 of WO 94/21503) to restrain horizontal movement of the upper frame means relative to the lower frame means.
  • a new form of steering damper is provided.
  • Each of the steering dampers in this design is connected with the top of an associated single convolution air spring, each damper being mounted for vertical movement so that it can move vertically with the top of the associated single convolution air spring.
  • each of the coupler pins is raised by an air cylinder.
  • a latch is provided under each coupler pin when raised to prevent the coupler pin from accidentally lowering.
  • the latch is mechanically released by an activating rod. When the activating rod is moved to that position where the latch is released, it will also engage an enabling valve which will permit air to be supplied to the coupler pin cylinder for withdrawing the coupler pin, that is to say for moving the coupler pin down to a disengaged position, and which valve will also cause the primary latch to be released.
  • each of the load carrying structures is transversely actuated by air actuator units, and these structures are locked in their centered position when the upper frame means is raised by the air spring assemblies by a gravity-operated center lock.
  • outboard supports which are manually adjustable for height by means of an internal gear box with a jack screw so that they can be raised or lowered to contact the under side of the trailer at the front or the rear.
  • the novel intermodal rail vehicle of this invention is indicated generally at 10. It is designed to be used with other intermodal rail vehicles of the same design to form a train of highway trailers.
  • two highway trailers are illustrated, one being a leading highway trailer which is indicated generally at 12, and the other being a trailing highway trailer which is indicated generally at 14.
  • the highway trailers 12 and 14 form no part of the present invention and are of the type shown in WO 94/21503 in FIGS. 10 - 13 and 16.
  • each of the highway trailers is provided with a main frame 16, a forward landing gear 18, highway wheel assemblies including wheels 20.
  • each highway trailer is provided with leading and trailing substantially identical coupling socket assemblies 22 and 24, respectively.
  • Each socket assembly may receive a coupler tongue.
  • each socket assembly is further provided with apertures (not shown) to facilitate securing the coupler tongue within the socket assembly via a coupler pin carried by the intermodal rail vehicle.
  • each of the intermodal rail vehicles of this invention include leading and trailing rail axle/wheel assemblies, 26, 28, respectively, which are in turn supported by leading and trailing lower frame means indicated generally at 30, 32, respectively.
  • leading and trailing lower frame means indicated generally at 30, 32, respectively.
  • the term leading and trailing is used for convenience only.
  • the wheels to the left may be considered the leading wheels.
  • Each of the lower frame means include a pair of longitudinal side frames 34 which are parallel to rails 35 (FIGS. 4C-4E) and transverse frames 36 (FIG. 3).
  • a reaction link 38 interconnects adjacent transverse frames.
  • the axle/wheel assemblies are in turn supported in the side frames by bearings within bearing supports 40. While the lower frames 30, 32 are structurally different from that shown in WO 94/21503, they are essentially the functional equivalents thereof.
  • the upper lifting frame means includes a pair of longitudinally extending beams 44, and transversely extending leading, trailing and intermediate beams 45.1, 45.2, and 45.3, respectively.
  • the upper lifting frame further includes laterally outwardly extending spring mounting plates 46, there being two plates associated with each wheel of each axle wheel assembly.
  • one of the upper beams 44 has welded thereto four upper spring mounting plates, two of them being positioned before wheels and two being positioned after wheels as best shown in FIG. 3.
  • each of the side frames of each of the lower frame means 30, 32 also carries lower spring mounting plates 48 before and after an associated wheel, the spring mounting plates 48 carried by the side frames 34 of the lower frame means being in vertical alignment with the spring mounting plates 46 carried by the upper frame beams 44.
  • Each of the spring mounting plates has two ears 48.1 and 48.2 (FIG. 7A) which are disposed 180 degrees apart from each other, the function of which will be discussed later. It should be noted that in this invention, as contrasted with the invention shown in WO 94/21503, there are two air spring assemblies for each rail wheel or a total of eight air spring assemblies for each intermodal vehicle as opposed to four in WO 94/21503.
  • each spring assembly which is indicated generally at 50, has a lifting capacity of approximately 16,200 lbs. at 100 psi, all of the spring assemblies have a lifting capacity of approximately 129,600 lbs. at 100 psi.
  • a spring assembly is mounted at each corner of each of the generally rectangular lower frames 30, 32.
  • each of the spring assemblies consists of a single two-convolution spring 52 and may further include a single one-convolution spring 54 (FIG. 6).
  • the two springs 52 and 54 of each spring assembly are secured on top of each other, with the one-convolution spring being disposed above the two-convolution spring.
  • a mounting plate 56 is disposed between the two springs 52, 54.
  • the mounting plate 56 is provided with two ears similar to the ears 48.1 and 48.2 on the lower mounting plate, which ears are disposed 180 degrees apart from each other.
  • Each ear receives the upper end 58 of a telescoping strut, the lower end 60 of the telescoping strut being secured to the ears on the lower spring mounting plate.
  • the upper strut 58 telescopes within the lower strut 60 and, therefore, the struts 58, 60 vertically guide the upper mounting plate.
  • the one-convolution spring 54 there is no such guide for the one-convolution spring 54, and therefore it may move from side to side in a horizontal plane.
  • Steering means are provided for steering each of the lower frames 30, 32 with respect to the upper frame.
  • the steering means are of the same type shown in WO 94/21503, and will not be described further.
  • WO 94/21503 discloses the use of steering dampers (96 in WO 94/21503).
  • novel steering dampers are provided.
  • These steering dampers which are indicated generally at 62, are best shown in FIGS. 6, 7 and 8.
  • Each steering damper consists of annular rubber members 64 which are bonded onto an inner sleeve 66 and an outer sleeve 68, respectively, a plurality of annular rubber members being stacked together.
  • the inner sleeve 66 is secured to a mounting bar 70 of circular cross section, the mounting bar in turn being provided with an internal bore 70.1, circular in cross section, and a threaded bore 70.2 at the other end.
  • a mounting stud 72 extends through the bore 70.1.
  • a steel cylinder 74 is carried by one end of the mounting stud 72, the steel cylinder being secured in place in any desired manner.
  • a spacer assembly 76 is disposed between the cylinder 74 and the mounting bar 70, the spacers of the spacer assembly being provided with suitable bores to receive stud 72.
  • a collar 78 is welded to the downturned side 46.1 of the spring mounting plates 46 as best shown in FIG. 8.
  • a mounting cylinder 80 which has an internal diameter just slightly larger than the external diameter of the collar 78 and outer sleeve 68 is used to trap the outer sleeve in an assembled position.
  • the mounting cylinder is provided with an inner annular member 82 which can bear against one end of the outer sleeve 68.
  • the other end of the outer sleeve 68 is forced into engagement with the collar 78 and is held in place by bolts 84.
  • the steel cylinder 74 is received within a mounting guide 86.
  • the cylinder 74 will travel vertically within the mounting guide 86.
  • considerable restoring force will be applied by the damper.
  • the upper lifting frame means 42 is provided with leading and trailing upwardly presented substantially identical load carrying structures indicated generally by the reference numeral 100.
  • Each upwardly presented load carrying structure includes a generally rectangular trailer support plate 102 (FIG. 4A) having an upper trailer support surface 102.1.
  • the support plate is supported upon the upper frame means for rocking, rotational, and side-to-side movement.
  • a pair of transversely spaced apart half-moon side plates or rockers 104 are welded or otherwise rigidly secured to the bottom of the plate 102.
  • rockers are in turn supported for rocking movement by rocker supports 106 (FIGS. 16, 17 and 23), the rockers 104 being maintained in contact with the rocker supports 106 by inner and outer guide plates 108.
  • the rocker supports 106 are in turn interconnected with an intermediate plate 110 which has a downwardly extending ring 112 secured thereto, the ring 112 being positioned about an inner ring 114 which is a portion of a coupler base weldment indicated generally at 115 and best shown in FIG. 14.
  • the ring 114 is welded to a trailer support base plate 116.
  • each of the trailer support base plates 116 is mounted for transverse movement on cross frame members 118, 120, 122 of the upper lifting frame; frame member 120 being provided with a transverse slot (no number) which receives a guide assembly indicated generally at 124 (FIG. 4A). While plate 116 rides directly on cross frame member 118, the weldment 115 includes transverse support bars 117.1 and 117.2 which ride upon the cross frame members 120, 122, respectively. In order to facilitate controlled side-to-side movement, a force transmitting frame weldment indicated generally at 126 in FIG. 23 is mounted below the trailer support base plate 116.
  • the weldment consists of L-shaped side plates 126.1 and 126.2 which are fastened to the bottom of plate 116, and a transverse brace 126.3. Disposed between the frame assembly 126 and the upper frame beams 44 are first and second air actuators 128.1 and 128.2. As can best be appreciated from an inspection of FIG. 23, when the first actuator 128.1 is charged with compressed air, it will expand and move the coupler base weldment 115 sidewards through the force applied to force transmitting frame assembly 126. The second actuator 128.2, when charged with air (and when air is discharged from the first actuator 128.1), will move the coupler base weldment the opposite way. This sideward movement of the coupler base weldment assists in positioning the trailer on top of the load carrying structures 100.
  • a coupling centering lock assembly indicated generally at 130 (FIGS. 4A, 4B and 24) is provided.
  • This centering lock assembly cooperates with a transverse member 131 carried by right and left longitudinally extending members 132.1 and 132.2 of the lower frame.
  • the lock assembly includes a downwardly extending plate 134 which is rigidly secured to the transverse support bar 117.2 by a fastener.
  • the lock assembly further includes a lock plate 136 which is slidably supported on the downwardly extending plate 134.
  • the lock plate is provided with a pair of laterally spaced apart vertically extending apertures 136.1, 136.2, each of which slidably receive a spacer 138.
  • One side of the spacer is positioned against the plate 134 and the other side is positioned against a surface 136.3 (FIG. 4B) of the lock-plate 136, the parts being held together by fasteners 142.
  • the lower end of the lock plate 136 will cooperate with cams 146 carried by beams 44.
  • the operation of the lock mechanism can best be appreciated from FIG. 24.
  • the coupler base weldment 115 (FIG. 14) further includes a coupler tongue housing, indicated generally at 148, to be supported by the trailer support base plate 116 adjacent centerline 33 (FIG. 4A).
  • the housing serves to support the apertured coupler tongue weldment 150 (FIGS. 10 - 12).
  • the weldment includes a main tongue 152 which is provided with an aperture 152.1, doubler plates 154 (FIGS. 11 and 12) which are welded to the top and bottom sides of the main tongue, and pulling lugs or ears 156 which are also welded.
  • the coupler tongue weldment has a generally T-shaped appearance when viewed from the top.
  • the coupler tongue housing 148 includes a vertically extending plate 158.
  • Spaced apart side plates 160.1, 160.2 are welded to the plate 158 and are spaced apart a distance sufficient to receive the portion of the coupler tongue weldment having the ears 156 as can best be seen from FIG. 9.
  • coupler tongue guides 162.1 and 162.2 At the inside ends of the side plates 160.1 and 160.2 are coupler tongue guides 162.1 and 162.2. It can be seen from FIG. 9 that the guides 162 restrain the movement of the ears 156 away from the centerline 33. The movement of the tongue towards the transverse centerline 33 is restrained by a guide block 164 (FIG. 10) which is mounted on wall 158 between the side walls 160.1 and 160.2.
  • the tongue weldment is assembled within the C-shaped housing (formed by the vertical plate 158 and spaced apart side plates 160.1, 160.2) by merely dropping the eared portion of the tongue weldment 150 within the C-shaped housing and then by closing the upper end of the C-shaped housing by a cover plate 166 which is secured in place by suitable bolts.
  • a portion of the weldment 150 is supported at all times by a coupler tongue support 168 (FIGS. 4B and 10) in the form of a spring-biased pin, which can telescope within a vertical housing 170.
  • a coupler tongue support 168 (FIGS. 4B and 10) in the form of a spring-biased pin, which can telescope within a vertical housing 170.
  • another portion of the weldment 150 may be supported by a bar 172 carried on the trailer support plate 102. It can be seen from an inspection of the various figures which show the coupler tongue weldment that the coupler tongue weldment is supported for limited pivotal, rolling, and pitching movement.
  • a U-shaped yoke assembly 174 is provided.
  • the yoke assembly includes side members 174.1 and 174.2 (FIG. 13), provided with inturned ends 174.11 and 174.22, respectively, and bight section 174.3.
  • the side members and bight section are welded to the side plates 160 and vertical plate 158.
  • the bight section is provided with an enlarged portion 174.31, which is a channel shaped member welded to the bight portion.
  • the leading and trailing bight portions 174.3 are interconnected to each other by a continuous draw link or shackle assembly indicated generally at 176.
  • the shackle assembly includes an upper member 178 and a lower member 180.
  • a downwardly extending transverse support member 182 is welded to the bottom side of the lower member 180 and is received within a pair of brackets 184, the brackets in turn being secured to the top of transverse beam 45.3.
  • the support member 182 is secured within the brackets 184 by a conventional fastener, not shown.
  • the upper and lower members 178, 180 are also secured together by a fastener 186.
  • each of the members 178 and 180 are generally C-shaped in cross section.
  • One or the other may be provided with an intermediate spacer 188 which is disposed between adjacent enlarged portions 174.31.
  • the spacer may be a separate piece. It can be appreciated from an inspection of FIGS. 4 and 4A, that if a pulling force is exerted on the leading coupler tongue 150, that this same pulling force will be transmitted to the trailing coupler tongue 150 by the continuous draw link 176. Likewise, if a compressive force is exerted on the coupler tongue, as may happen during braking, the same compressive force will be transmitted through the link 176 to the trailing tongue 150. Thus, a continuous drawbar 150, 176 is provided.
  • the aperture 152.1 in the tongue will overlie a corresponding aperture 190.1 (FIG. 4B) formed within a vertically extending sleeve 190 which receives a coupling pin 192.
  • the sleeve 190 is suitably welded or otherwise rigidly secured to the plate 102 with its upper surface 190.2 lying in the same plane as surface 102.1.
  • the coupling pin 192 is adapted to be moved from an initial at rest position shown in FIG.
  • a leading trailer 12 (FIG. 1) is to be assembled onto the intermodal rail vehicle 10
  • it will be moved to the right as viewed in FIG. 1, causing the trailing socket assembly 24 of the highway trailer to ride up upon a loading ramp 196 and then onto the surface 102.1 of the support plate 102.
  • This movement will be continued until the leading edge of the socket assembly 24 abuts against the bar 172.
  • a primary latch mechanism indicated generally at 200 (FIG. 25) will engage a portion of the socket assembly and hold it on the support plate 102 until such time as the pin 192 can secure the socket assembly to the intermodal rail vehicle.
  • the primary latch assembly consists of a latch weldment 202.1 - 202.4 rotatably mounted on a transversely extending pin 204 carried by a pair of depending ears 206 (FIG. 18) secured to plate 208.
  • the plate 208 is in turn rigidly secured in any conventional manner to the trailer support plate 102.
  • the latch has a hook portion 202.1 which is adapted to engage the side of a lug (not shown) carried by the coupler socket assembly 22.
  • the hook portion 202.1 is carried by two spaced apart arms 202.11 and 202.12 which are welded at the end remote from the hook to a sleeve 202.4.
  • the arms 202.11 and 202.12 are braced by gussets, only gusset 202.13 being shown.
  • the hook portion 202.1 is normally biased to its upper position by springs 210 which are disposed between bosses 208.1 on the plate 208 and bosses 202.21 carried by a first lever 202.2 of the latch.
  • the latch also includes a second lever 202.3 which is adapted to be engaged by an air bag 212 supported by a saddle assembly 214, the saddle assembly being in turn mounted upon the intermediate plate 110.
  • the springs 210 will force the hook portion upwardly with a loud click.
  • the air bag is inflated which will cause the lever 202.3, as viewed in FIG. 22, to move in a counterclockwise direction, lowering the hook portion 202.1.
  • the first and second lever portions 202.2 and 202.3 are formed from a single piece of angle iron which is welded to a sleeve portion 202.4 of the latch.
  • the coupler lock assembly includes a lock pin 222 which is adapted to pass through an aperture 190.1 in the sleeve 190 (FIG. 16).
  • the lock pin 222 is carried by a support plate 224 and is normally biased by a spring 226 to the centerline of the coupler pin.
  • a flag 230.1 will be moved from its "safe" position (see FIG. 19) to another position where it will indicate that rail transport of the highway vehicle may be unsafe.
  • a coupler pin cylinder enabling valve indicated generally at 236, will be engaged, which will permit the operation of the air cylinder assembly 194 to permit retraction of the coupler pin 192, and which will also introduce air into the air bag 212, to cause the primary latch 202.1 to moved to its released position shown in dotted lines in FIG. 22.
  • outboard supports 240 are provided. These supports are mounted upon the upper frame and may be manually adjusted for height via an internal gear box with a jack screw.
  • intermodal rail vehicle of this invention should be apparent from the above to those having ordinary skill in the art.
  • intermodal rail vehicles are bi-directional, and as the trailers designed for use with the rail vehicles of this invention are provided with virtually identical leading and trailing coupler socket assemblies, it is very easy to make up a train of highway trailers. In addition, such a train has improved stability over those previously known due to the unique design features of this intermodal rail vehicle.
  • the intermodal rail vehicles can be fabricated without undue expense.
