Abstract:
A centering mechanism for a tunnel of an articulated vehicle includes a pair of control members connected to opposite ends of a transversely extending arm. The members extend to transverse links that connect spaced portions of the adjacent vehicle bodies and act as a torque transmitting linkage through a cross-over link pivoted on one of the vehicle bodies. The members are connected at the midpoints of the transverse links so that they are displaced one-half the relative displacement of the vehicle bodies as they negotiate vertical curves and thereby maintain the tunnel centered.
Abstract:
A truck-train system uses a railway dolly or bogie to support the front end of one truck-trailer and the rear end of another truck-trailer. A pair of truck-trailer support members are pivotally connected to the railway dolly. They are provided with a fixed incline ramp to raise and guide the truck-trailer onto the respective support member. The railway dolly is provided with a standard railway compressed air braking system with an air hose retrieving device to store the air hose. The railway dolly is also provided with standard railway couplers at each end. These couplers are adapted to retract or vertically rotate to a position below the surface of the incline planes.
Abstract:
A dual-mode semi-trailer having over-the-road or highway running gear with rubber tired wheels in which a demountable flanged rail wheel bogie is employed, the body being supported upon the highway running gear during over-the-road travel by air-spring elements and being supported upon the rail wheel bogie during travel over railroad tracks, structure being provided to selectively raise and lower the highway running gear for selective use in the railroad mode or highway mode of travel, structure also being provided to attach or detach the rail wheel bogie from the body for operation in the rail or highway mode of travel, the semi-trailers bodies being couplable end-to-end to form a train of multiple semi-trailers in the railroad mode of travel. The highway running gear may be of the single axle or tandem axle type, in each case each axle carrying sets of tires of conventional size allowing loads as high as legally permitted to be carried over the road in the highway mode of travel, the highway running gear being slidably mounted to the vehicle body allowing adjustable foreaft positioning to further enhance permissable highway load capacity due to improved weight distribution, the rail wheel bogie being preferably of the dual-axle type.
Abstract:
A railway car comprises a center sill with a crossbearer, webs and end bolsters extending across thereof. A light side stiffener interconnects the projecting ends of said webs and spans between the bolster and the crossbearer. A shear plate covers a trapezoidal end frame extending from the bolster. The frame includes inclined braces buttressing a pair of cantilevered brackets projecting toward and horizontally overlapping similar brackets of the adjacent car.
Abstract:
A container carrying rail-highway vehicle in the form of a semitrailer chassis including an elongated center sill box extending longitudinally of the vehicle, a front box-type transverse sill attached to a forward portion of the center sill and a rear box-type transverse sill attached to a rearward portion of the center sill member. Two side beams are further provided and are attached at each end thereof to the front sill and rear sill, respectively, on either side of the center sill. The side beams are disposed from a generally higher position in the front of the vehicle to a lower level at the rear of the vehicle and are further attached to the center sill by a plurality of transverse outrigger members which extend between the center sill and each of the side beams. The vehicle is further provided with at least a pair of retractable highway wheels on a rearward lower surface of the trailer, a coupling device for coupling the trailer to a next adjacent trailer and a coupling device for coupling the trailer to a separable rail bogie on a rear undersurface of the vehicle. The center sill of the semitrailer body has a gooseneck, fish belly configuration which in combination with the side beams provides high bending stability in the gooseneck area of the center sill so that high compression and tension loads can be taken through the center sill.
Abstract:
Novel highway trailers can be mounted on railtruck assemblies to form a train of highway trailers, the railtruck assemblies including a conventional railtruck which supports a novel intermodal adaptor. The novel highway trailers include a forwardly extending tongue and coupling structure at the rear to which may be secured the tongue of a following trailer and the intermodal adaptor of a railtruck assembly. The intermodal adaptor is mounted on the center plate bowl of the bolster of the railtruck. The adaptor includes locating structure adapted to be received within the coupling structure of a leading highway trailer, which locating structure permits the leading highway trailer and intermodal adaptor to become aligned with each other upon relative movement. The intermodal adaptor further includes securing structure capable of maintaining the locating structure within the coupling structure of the highway trailer in a completely mounted position, a coupler pin, and a shifting structure capable of moving the coupler pin from a lower position to a raised position where it couples the forward end of a tongue of a following trailer to the rear of the leading trailer and the intermodal adaptor.
Abstract:
A device for reducing the lateral movements of a railway vehicle caused by irregularities in the rail. The railway vehicle contains at least one wheel which is mounted for limited rotation around a generally vertical axis. A separate power-operated control means for performing limited rotation receives signals from a sensing means so that the wheel is turned around the generally vertical axis in such a direction that the effect of the irregularities are reduced.
Abstract:
A system and method for transporting an airfoil, which has a root end, a tip end, and a midsection, over a railroad utilizing a first railcar coupled to a second railcar. The system includes a bracket fixed to the root end of the airfoil and connected to the first railcar, and, the bracket is oriented to align the tip end of the airfoil toward the second railcar. A sliding support is connected to the first railcar at a position between the bracket and the second railcar. The sliding support is adapted to engage the midsection of the airfoil and support the airfoil while enabling the airfoil to move laterally. A lateral guide structure is connected to the second railcar, and aligned to engage the airfoil to limit its lateral movement.
