Abstract

Improved semi-trailers (1) for rail or road travel have a detachable road bogie (2) and a detachable rail bogie (4). They can therefore travel on rails with the rail bogie (4) alone and by road with the road bogie (2) alone, with all the ensuing advantages as regards construction, operation and organization. Other improvements concern means for mounting the rail bogie (4), means (5, 6) for coupling the semi-trailers, and in particular adapter bogies (C-A) for mounting on the ends of a semi-trailer or a series of semi-trailers to permit their incorporation into a normal railway convoy, in which coupling between vehicles is effected by hooks and buffers. The improvements also permit substantial simplification of the hydraulic circuits of each semi-trailer which are limited mainly to the circuits needed to raise or lower the rear end of the road bogie (2).

Description

"Perfected Trailers can travel on rail and road."

This invention relates to trailers that can travel on rails as rail cars or road as road vehicles, in which the transformation of rail semi-trailer truck trailer or vice versa can be performed without the use of crane, lifting platform or other similar systems.

The idea of ​​having trailers that can run either on rails or on the road is not new; the state of the art includes several types of road vehicles / - rails already in circulation, as well as numerous patents and applications which we cite the most relevant below: 1) European Patent Application 84308107.6 of N. Trailer Train Limited on a transport system consisting of semi-trailers in which the road bogie is irremovable, with wheels can be lifted out of the plane of the rails when the semi-trailer rests on a rail bogie: to provide a semitrailer train, each semi-trailer can be connected to the preceding by laying it on the rail bogie.

2) US Patent n. 4342265 on a trailer in which the road wheels and railway wheels are both removable: rail road wheels are lifted while qur road is raised railway wheels.

3) European Patent A pplication n. 84306544.2 "Intermodal transport" for a container that can be transported on rail and road.

4) International Application No PCTUS. 81/01162 28 / 08.1981 for a convertible vehicle road / rail and wheel support system. 5) USA Patent No. 4448132 for a convertible vehicle road / rail bogies with road and rail bogies can rise alternately to allow either walking on road or walking on rails. 6) French Patent n. 743,409 on a car platform that can travel on both road and rail. 7) USA Patent No. 4416571 "transport system on both road and rail", which consists of an elongated container which can be transported either on rails, or on the road.

8) European Patent n. 0143614 regarding a transport system with semitrailer road / rail wherein the rail bogie is removable while the road bogie is irremovable, but it can be raised during the movement on rails.

9) Patent US 2,263,578, 2,513,552, 2,564,311, 2,709,069, 2,879,719, 2,889,715, etc ... From the state of the art mentioned above, appears in no case the existence of semi-trailers road / rail with which it be possible to travel on the road with only the road bogie or rail with only the rail bogie. Indeed, all the vehicle described in the Patent, to perform the service road / rail, is based on a removable rail bogie or on an irremovable road bogie that is permanently connected to the vehicle so that, only when the above mentioned vehicles traveling on the road, we can reduce their tare weight of the unused bogie, ie the rail bogie: when the vehicle is traveling on rails, road bogie is not introduced, but simply raised above the plane of the rails and locked in this position. These Patents do not clear the existence of a single bogie adapter, indifferently applied either to the rear end is at the front end of a road vehicle / rails, to permit introduction into a convoy normal rail vehicles. Vehicle that runs on both road and rail are mostly semi-trailers for road use are placed with the front end on the socket of a tractor and, during the movement on rails, are connected by rear end, through a coupling device applied to its front end with the rear end of the semitrailer which precedes it. The prior art also includes numerous solutions to the coupling problem between the vehicles, the problem of the application of the rail bogie, the uprising of the road bogie, automation needed to perform the lifting of the vehicles plan etc ....

The impossibiliter detach the road bogie when the vehicle travels on rails, is ultimately the cause of the four major disadvantages listed below:

A) greater Tare rail semitrailer, because it is increased by the weight of the road bogie (about 5 tons); this prevents the use of semi-trailers that road exceed 35 tons gross weight, if we want to limit the burden on each of the two axles of the rail truck to 20 tons, in accordance with regulations in certain countries.

B) The need to provide semi-trailers of all these means for lifting on the plane of the rails and block and ensure in this position the wheels of the road bogie, when the semi-trailer travels on rails.

C) Inability to use the road bogie when the semitrailer travel on rails, to absorb quickly the cost, ie reduce both the number of bogies Railway stations, railway as the number of road bogies relative to the number of chassis semitrailers. In other words, failure to separately use the following components of each trailer: a) chassis generally closed; b) rail bogie; c) the road bogie. D) higher costs of the semitrailer road / rail: the assumed cost of road bogie and the lifting and blocking devices necessary for the running rail, is about 1/3 of the cost of the full trailer. In addition, the absence of a single bogie adapter indifferently applied to the posterior or anterior end of the semi-trailer to allow insertion into a normal rail train leads among other higher costs of operation and maintenance.

The main purpose of this invention is to eliminate the disadvantages caused by the application to semitrailers road / rail of an irremovable road bogie.

Another important object is to provide a single type of adapter bogie applied indifferently to either of the two ends of a train of one or more semi-trailers for road / rail to enable the rapid formation of convoys mixed trained normal rail vehicles and bimodal road / rail vehicles.

Another important goal is to improve the functionality of bimodal semi-trailers road / rail by providing the means which enable quick installation as well as the rail bogie bogie adapters.

Another important goal is to provide means making it safer and faster between the hitch trailers to form a railroad train.

For such purposes, the invention solves the following problems: The first problem is solved by applying the semi-trailer with a removable road bogie that is provided with an independent frame which comprises elastic suspensions pneumatic type or in any case fluid dynamics, which can be connected for operation to the pneumatic system of the vehicle, to allow, with the lifting and lowering of the semitrailer, the application of the rail bogie: the bogie has means which allow in the mounting and dismounting of semi-trailer, which is provided for this operation. A second problem is solved with the design of a bogie adapter bivalent, that is, can be applied indif ently previously or subsequently semi-trailer, using both coupling means r e e cipro that between the semi -trailers that the means that allow mounting the rail bogie. A third problem is solved by this invention; This is the problem with the provision of an automatic coupling device applicable to both trailers that bivalent adapter bogie; this device, with larger tolerances positionneles enables coupling by a lowering movement of the front part of the semi-trailer, without using either elastic bumpers, or draw hooks.

The fourth problem solved by this invention relates to the removal of the rail bogies or the bogie bivalent adapter, with a device that restricts the vertical displacement of the rear end of the semitrailer, i.e. a device which prevents further movement about. 100mm. necessary to jump, with the integral coupling pin of the semitrailer, the center plate of the rail bogie and of the adapter bogie.

As illustrated in fig .. 1 and 1a, the main feature of the semitrailer 1 is removable road bogie 2 arranged in the region 1a of the plane 1b, with fluidodynamic independent suspensions, which can be connected to the pneumatic circuit of the semi- trailer.

The bogie can be hung on the trailer or hook the trailer as well laterally and posteriorly, with adequate resources; in the embodiment illustrated in these figures, the bogie assembly is laterally conducted with T-profile, 2a, mounted transversely to the bogie, threaded through the splines 1 1, defo rm ei nt i that ob t enu esdansunb Ti ndu 1 are fixed to the frame 1b of the semitrailer by 1c beams.

Maneuvering introduction of the bogie, road 2 can be performed using various means, such as a floor P P 1 provided with rollers or a spur F also sliding fig.1.

To facilitate insertion of the road bogie in the floor P, fig.1, can be connected with an extension cord, the circuit of the pneumatic suspension of the road bogie to the circuit of the trailer brakes, to lift the transverse T-2a , the height needed to introduce them into the flutes T-section, 1a 1, placed below the plane of the semitrailer.

With the spur F, fluid dynamic mechanical type, the operation of introducing the road bogie can be identically carried out by directly acting on the suspensions of the spur F.

The road bogie can be also applied by the rear part of the semitrailer by moving it in the longitudinal direction after having placed the end of the semi-trailer on the cylinders 9, fig.1. In FIG. 2 are illustrated the operations for the plate change road / rail through the use of an F spur or floor P.

In the first manner, during the phase a, the end of the load plane 1b of the semi-trailer is lifted using the air suspension of the wheels of the road bogie 2b 2, fig. 7, to insert the pin 3 integral with the semi-trailer in the groove 4c of the interface 4 of the rail bogie. In phase b, after the coupling of the rail bogie CF, the road bogie is removed with the spur sliding F, actuated by fluidodynamic means, whereas the semitrailer is placed previously on its legs 8, thereby allowing the tractor fig. 1, to detach from the 7 previously applied coupling pin to the plane of the semitrailer.

In the second way, step c 1 of FIG. 2, the semi-trailer is moved so that the road bogie be fitted on the sliding floor P, placed on the rails, and then the rail bogie is moved and applied: suspensions of road bogie need only make small vertical displacements adaptation, since thanks to the floor P, the rear end of the semitrailer is automatically set to the required height to insert the pin 3 in the groove 4c of the interface of the rail bogie.

In step c 2, removing the road bogie with the plane P to which it is superposed in step c 1: the semi-trailer rests on the lugs 8 so that its front end is raised to suffisemment enable the coupling to another semi-trailer.

Step d shows two semitrailers after mutual coupling: the coupling is obtained by lowering the front end of one of the two semi-trailers so that the cavity όa its coupling device overlays the sphere 5 mounted on the rear end of the other semi-trailer. The coupling between the semi-trailers on rails is performed with the device illustrated in fig. 3 e 4. This device consists of two spherical surface body, a hollow 6 mounted at the front end of each semitrailer in correspondence with the longitudinal plane of symmetry and the other spherical 5 obtained in a block of molten steel, placed at the rear end of each trailer. The sphere 5 is mounted on a slide 10 sliding in a guide 11, reactionnée by an elastic means 8 rubber.

A pin 13 through the lever 14 ensures the mutual connection of the sphere 5 in the groove 6a so as to allow relative rotation about an axis normal to the plane of iron to allow the entry in bends even with a minimum radius of 90 or 75 mm. An important feature of the device lies in the movement coupling which is carried out by applying, by a movement from top to bottom, the cavity 6a on the sphere 5. The outer surface of the sphere is expanded to +/- 105 °, from the vertical, on the longitudinal plane and approximately +/- 80 ° to the transverse plane of the vehicle. The use of this spherical body 5 is justified by the need to allow simultaneous rotations around two axes Orthogonal them, with the resulting clamping force of the coupling inclined relative to the vertical, a maximum of +/- 80 ° in the longitudinal plane (vertical force of 20 tons and horizontal force of 100 ÷ 120 tons), and +/- 20 ° in the transverse plane (vertical force of 20 tons and 10 tons of horizontal force to balance the centrifugal force in the rotating). The device which permits the mounting of the rail bogie CF to the rear end 17 of the trailer, consists of a box girder 4, fig. 5, 6, 7, and 9, also known as interface in this specification, which forms a groove 4c bounded by triangular plates 4a inclined downward: a coupling pin R 2, coupled to the step bearing R 1 of the bogie through the pivot R 3 provided with a die at the end, is secured to the lower surface of the interface. Blocking the interface 4 to the end of the trailer is carried out, after a pin 3 integral with the beam 17 of the transversa semitrailer is inserted into the groove 4c, Fig. 7, with a hook 4d held in the closed position by a latch 4b, and with two prongs 18 which are threaded into two tubular cavities 18a in the box beam 17; the lock is formed by a rod, provided with a handle 4 and remains in the release position the hook 4d 4f when the notch is inserted into the lateral edge of the interface. The interface can be pivoted around the pivot axis A 3 of the step bearing of the bogie, 180 °, Fig. 6, to permit coupling the bogie to the trailer, at both ends, with a rod threaded through the tube 19 which is integral therewith. To this end, we remove the interface studs 27 inserted into the holes 4h, which, because of the presence of the stops 27a, in only agree rotations of +/- 5 ° around the pivot axis R 3 center plate. The rotation of the interface is facilitated by an annular plate 23 integral with the bogie CF, on which it is placed thanks to rollers 24 so that its plane remains horizontal even during rotation, see Fig. 8. The plates 22, fig. 9, anti-friction material, intended to reduce friction which occurs during the coupling interface with the semi-trailer; the sliding of the prongs 18 in the tubular cavities 18a is facilitated by the presence of plates 18b anti-friction metal. Blocking the interface of the rail bogie to the semi-trailer, Fig. 9 is also provided, in an emergency, by two pins 25; each slide pin in one of two holes 4g of the crosspiece 17 of the semi-trailer and is inserted through the corresponding hole 4g1, with vertical axis, in the interface 4. The studs are manipulated by the levers 25a so as to unlock by along the interface 4 of the cross member 17, fig. 9, during maneuvers uncoupling of the rail bogie and bogie adapters. The AC adapter bogie illustrated in FIG. 10: FIG. 11 illustrates two options for which it is intended to allow the application to both the front end than the rear end of the semitrailer. It consists of a rail bogie CF like the bogie according to the improvements in question, wherein the interface 4 connected to the step bearing R is substituted with a 4CA interface functionally equal, but secured to one side of an AC box body 1 provided at one end of stoppers CA 1 / R and of the coupling device for traditional bogies and the other side, two CA 2 crosspieces, forming a frame, provided with auxiliary means for the locking with the frame 1b of the semi- trailer.

To facilitate the introduction below the plane of the semitrailer, CA crosspieces 2 have the ends CA 2 / E inclined downward, fig.10: CA 2 fins / A are also shaped to form a mouthpiece , to facilitate insertion of the pin 3 of the semi-trailer in the groove 4c, fig. 7, now their surface flush with the upper flange of the double T beams, CA 2. When the bogie adapter is not applied to the semi-trailer, Fig. 10, the interface and connected 4CA frames CA 1 and CA 2 are maintained in a horizontal position by a device 29, by means of a hook 29a which is engaged with the pin 28 secured to the rail bogie. This device 29 is also equipped with forks 29c which result in additional locking of the frame 2 CA with the frame 1b of the semitrailer, Fig. 10, 13, 14, when the bogie adapter is coupled to the semi-trailer: the maneuvers of the device 29 are performed with a small steering wheel 29d, supported by a 29th raven, which actuates gears placed in a box 29b.

For the coupling, Fig. 11, with the rear end of the semitrailer, the bogie adapter is applied in the same way as for the coupling with the rail bogie CF, using the same coupling means. the pin 3 integral with the interface 1b of the semitrailer and the other locking means of the AC frame 2 constituted by the hook 29c.

Adapter for coupling the bogie to the anterior part of the semitrailer coupling sphere 5CA is used similar to that used for coupling the semi-trailers each other; this sphere is pushed into the cavity 6a of the coupling device 6 of the semi-trailer: the additional locking means of the adapter bogie, fig.14 are the same hooks 29c which are engaged with the lower flanges of the double T-profile members the frame 1b of the semitrailer, which, in correspondence with the front end have a lower height.

So that the front end of the semitrailer of the frame can be supported on the frame 2 of the AC adapter bogie, fig. 11, the frame CA 2 is provided with means such as cubic or parallelepiped-shaped body 30, Fig. 12, 13 and 14, which are connected by hinges to the frame 30c. CA 2 and are rotatable so as to form a bearing plane with a height, i.e. equal to the height set by the 5CA coupling sphere to allow the locking of the adapter bogie frame CA2 with the frame 1b of the semitrailer in the area where the latter frame is at a lower height.

If 4CA interface adapter bogie is in a position such that it is impossible to apply it to the corresponding end of the semi-trailer, it is sufficient to rotate by 180 ° around the pivot interface 3 of the R crapaudine to permit application with the means provided for this: with the application of the adapter bogie, bumpers CA 1 / R, fig. 10 and 11 allow the coupling of the trailer with a conventional bogie.

The semi-vertical plates 30a, fig. 10, 12 and 14, are intended to center the front end of the semitrailer on the adapter bogie during the coupling procedure between the sphere 5CA and the hollow sphere 6a of the device 6 mounted at the front end of the semi- trailer: the judgment CA 3 also comes into play, preventing unnecessary longitudinal displacements.

In Fig. 15 and 16 is illustrated the operation of the anti-interlocking bar AI by the lever 33; this lever rotates about the pivot 33a, and is secured to a plate 33c; this plate has a shape such that, by pivoting when it is not engaged with the rod 34 operated by the lever 34 repowered by the spring 34b, it causes, with the small rod 33 and the link 33d, the rotation of the safety coupling 15 around the pivot 33f so that by superimposing the hollow sphere 6a to the sphere 5, the pins 15a of the safety coupling 15 mentioned above are inserted, fig.5, in holes 16 of the large plate forming the plane, providing additional coupling between the semi-trailers.

The pneumatic system that allows the lifting of the front part of the semitrailer through SP suspensions of road bogie be applied to the rail bogie CF or alternatively the bogie adapter, Fig. 17 comprises a limit switch 31 actuated by the anti-nesting AI bar when it is pivoted upwardly to allow traffic on the railway; the end of stroke, acting on the valves 36, defuses the level of valve 35 and causes lifting of the semitrailer, by inflation of the cylinders SP suspensions of road bogie: the air is provided by one of the tanks for this, and the maximum height is determined by the limit valve 32.

In the diagram in Fig. 18 are illustrated the devices that cause the intervention of the braking system of the semi-trailers for lowering the pressure of the air: this may be due to breakage of the pipe 21 of the pneumatic system, fig. 5 and 18, if the knife 21 which es't APLIQUE it and which is integral with the portion 6 of the coupling device is opposed to the pivot 15 integral with the element 5 of the coupling device in case celui- will suffer the damage.

Braking can also be caused by an operation of the fourth handle which acts on the latch 4b, see fig. 18.

The possibility of removing the road bogie thus revolutionizing the means of production and use of semi-trailers road / rail.

Indeed the chassis of the semitrailer, the rail bogie and road bogie, form three separable and interchangeable components, which can be constructed and used separately: this reduces the number of road or railway bogies relative to the number of closed frame or not of each trailer, since the use of both bogies can be done separately, but the use of the first excludes the use of the second. The use of semi-trailers of this invention allows a drastic reduction in the cost of vehicles for road / rail, with all the benefits that result.
