Definitions

  • GUIDE SYSTEM FOR VEHICLE CARRIAGES BACKGROUND OF INVENTION The present invention relates to tracking guide systems for railed vehicles, carriages, bogies and the like, and in particular to a switching or turnout system therefor.
  • switches have been made by employing a shifting, swinging or rotating rail portion or by providing a portion of the rail with a flexible section which may be bent to one side or the other of the track.
  • Switches have also been built without movable parts and the undercarriage or bogie itself provided with movable devices for selecting the turnout or branch spur track.
  • Such switching mechanisms are activated in advance of the bogies reaching the turnout section so that the vehicle may be easily led into the proper direction.
  • Switch systems wherein it is necessary to move rail sections or whole track portions have a great disadvantage. Succeeding bogies, vehicles or trains of carswhich are required to proceed in different directions must be widely spaced from one another, relative to their speed, to allow the turnout sufficient time to switch. It is therefore, not possible to provide closely following, high speed, single vehicles which must be switched into different directions. The forces required to move the mass of the switch, in very small time intervals would be too great and extremely difficult to properly regulate or govern.
  • German publication DAS No. 1,294,405 there is shown a system in which the running and guide rails are combined and which is provided with two pair of tracking guides, to direct the vehicle into the proper direction.
  • this system not only does the heavy combined vehicle rail have to be movably switched but since the undercarriage runs on tandemly arranged wheels, the possibility exists that the front wheels turn differently than the rear wheels. Should this occur then a catastrophy would be the inevitable result.
  • the switching of the heavy running and guide rails require a great deal of force, otherwise rather long switching times have to be dealt with. The latter factor prevents the use of closely following high speed cars.
  • the carriages have a plurality of wheels or rollers mounted on fixed axes, the rollers engaging the sides of the rail under normal travel conditions.
  • the system includes means for selecting the desired branch section turnout located in the vicinity of the branch section, whichmeans acts on the carriage independently of the rollers and the other masses of the vehicle.
  • the selector means comprises a single member mounted on the carriage shiftable transversely to the longitudinal axis of the carriage, between fixed stop abutments. The member is adapted to engage cooperating means mounted on the rail, in the branching section which causes it to abut the stop member resulting in a lateral movement of the carriage independently of any other force acting on it.
  • the rail means may be a fixed groove or pivotal tongue means adapted to engage and shift the carriage selector means.
  • the rail means acts as a cam while the carriage selector acts as a cam follower, both being cooperatively movable with respect to each other.
  • a system is further provided wherein the switching in the branch sections is accomplished with the minimum of force vectors applied to the carriage. This is accomplished by locating the force vectors, reducing the force vectors to two groups acting in transverse directional planes. At least one group having three vectors in the plane two of which act in one direction while the other one acts in an opposite direction. According to the present invention, one of the vector groups acts in a vertical plane and the other in a substantially horizontal plane. The force of the vectors is not critical, but their numbers are.

  • the present invention is embodied in a railed vehicle carriage or bogie comprising a truck body 1 on which support wheels 3 and 4, side guide wheels 6-9 and central pressure wheels 11 are journaled.
  • the carriage rides in a substantially enclosed hollow rail 13.
  • the rail 13 has a continuous slot 14 in one of its faces through which a connecting hanger or fastening means 15 extends by which the vehicle cab container or car itself may be secured, from which only a portion, comprising the central pole 17, is shown.
  • other linking elements, springs and supports for the vehicle are provided.
  • the carriage is provided with a tracking disk 19, which is freely journaled about a transverse axle above and between the support wheels 3 and 4.
  • the tracking disk 19 is freely slidable along its axle between a pair of opposed abutment stop members 20 and 21 which are resiliently urged toward the hub of the disk 19 by springs 22.
  • the freely rotatable disk is preferred; however, a slidable wedge, cam or the like could be used instead.
  • the elements 3,4, 6 to 9 and 11 are preferrably freely rotating rollers of known conventional structure.
  • the hollow rail 13 has a rectangular cross section.
  • the inner surfaces 24, straddling the slot 14 form the running rails for the supporting wheels 3 and 4 which are commonly journalled about a transverse axis in the center of the truck body I.
  • the hanger 15 extends downwardly between the wheels 3 and 4.
  • the guide wheels 6 to 9 are each mounted about vertical axle shafts and are arranged in pairs to the front and rear of the supporting rollers.
  • the pressure wheels II are mounted on horizontal axle shafts arranged substantially in the plane of the axle shafts on which the guide roller pairs 6 and 7 and 8 and 9, respectively are mounted.
  • the wheels 11 engage the upper inner surface of the rail 13 at the front and back of the carriage and act to maintain the supporting wheels 3 and 4 firmly in contact with the rails.
  • This provides a closed rail system, in which the carriage and/or the wheels may not be derailed. It is possible, to provide a monorail system with the wheel arrangement substantially shown without a rail having a box-like profile.
  • the upper portion of the hollow rail is provided with a current conductor track for energizing the motor. etc., and for conducting leads for information signalling, etc.
  • the carriage is provided with current contacts, antennae and the like.
  • the tracking disk 19 Normally, when the carriage is outside of a switching or turnout zone the tracking disk 19 does not function. However, just before entering the switching zone, the disk 19 engages within a slotted guide track 30, 31 positioned along the center line of the upper inner face of the rail, and the tracking disk 19 thus becomes centered preparatory to be forced to one side or the other.
  • the centered tracking disk 19 is diverted to the left or right by a pivotal tongue 26, so that it rides against the outer edge of the guide track 30, 31, while in joining or combining switch seen in FIG. 4 the disk 19 is directed by a stationary curved deflector portion 28 onto the outer edge of the track 30, 31.
  • the tracking disk 19 is shifted on its journal axle until it hits one of the abutment stop members 20 or 21.
  • the abutment stops 20 and 21 cooperate with the auxiliary track 30, 31 to take over the guide functioning of the wheels 6 to 9 and move the carriage in the desired direction.
  • the tracking disk 19 On entering the combining switch (FIG. 4) the tracking disk 19 is caused, by the auxiliary track 30,31 to be immediately shifted to its extreme lateral position, even before the carriage enters the switching zone proper.
  • the disk 19 therefore takes over the side guiding function from the rollers which so engage the widened sides of the rail and only later is guided back to its middle position, the convergence of the side walls.
  • a conical trap 35 is placed immediately after the combining switch (i.e., the frog-like guide track 30,31) to insure that the disk 19 is returned to its mid-position.
  • the magnetically oper ated tongue 26 shifts the disk 19 positively to one side or the other unit it hits either of the abutment stop members 20 or 21.
  • the disk 19 takes over the guide function and steers the carriage into the proper branch. Since the cross section of the rail enlarges in the direction of travel the guide wheels 6 to 9 do not exercise their normal functions.
  • the tracking disk 19 engages within a reverse steering slot member 33 which causes the disk to again take a middle position.
  • the conical trap 35 seen in FIG. 4 may be substituted for the angular slot member 33, if desired.
  • the disk 19 is preferably formed with a bevelled. peripheral edge and the portions of the carriage lying before it are removed or built so as to be open. Similarly the portions lying before the blade tongue 26 are open and free, and the blade itself is pointed. In this manner the disk can not jam or get stuck in the tongue or in the directional slots. The principle of a pointed or knife edge is followed.
  • the aforedescribed tracking and guide system is highly suitable for use with hollow rail-overhead trolleys and in particular for overhead fixed guide rail conveyor systems.
  • the vehicles, cabs, etc., employed in such systems exert only a relatively small force on the rail chassis itself which makes the appplication of this system suitable.
  • the overhead system is shown, it will be obvious that with only minor modification of the position of the supporting wheels, the system may be adapted to a ground level or below ground level system, and the rail provided with a slit on its upper face through which the hanger for the vehicle body extends.
  • FIGS. 6 9 indicate the various cross sections of the rail 13 as its branches converge as in FIG. 4 or diverge as in FIG. 5.
  • the sectional lines are the same in both, FIG. 4 and FIG. 5, except for the fact that they must be viewed in opposite directions, depending on the direction of travel indicated by the arrows.
  • FIG. 6 shows the normal cross section just prior to or just after the switching zone.
  • FIG. 7 shows the initial widening or final convergence of the hollow rail 13, the slit 14, and the auxiliary track 30,31.
  • FIG. 8 shows the splitting of the auxiliary track into two portions or initial convergence.

  • FIG. 10 shows a tracking disk 40 of the type shown in the main embodiment which may be shifted sideways (dotted lines) as seen by the double arrow.
  • FIG. 11 there is shown a tracking disk 42 mounted on a transverse axle joumalled at each end in bearing mounted on a a Y-shaped yoke, the stem of which pivotally is mounted on a longitudinally disposed axle 43.
  • the yoke swings about the pivot axle 43 in the arc shown by the double arrow permitting the disk 42 to swing as indicated by the dotted lines.

  • FIG. 13 depicts a variant employing two tracking disks 47 and 48 adapted to selectively engage the guide track 53, by raising and lowering the disk in the direction of the arrows as required.
  • any one of the aforedescribed systems permits the immediate succession of vehicles, one behind the other, at high speeds. Switching two adjacent vehicles in opposite directions is simple because the mass and also the translatory distance travelled by the switching member, namely the tongue 26 or the tracking disk 19 is small. It is thus possible to arrange two or more switches in tandem following each other. Since the switch comprises only one rail mechanism for each vehicle, the possibility of derailment or having the vehicle become stuck in a switch is virtually impossible, even if the switch mechanism is momentarily in the wrong position. Since the switch actuation needs to overcome only small forces and is generally applied to fixed members, it can be simply and economically built to have a strong and long life.

  • a guide rail or auxiliary track 62 is provided which is adapted to engage the tracking disk 63 holding the carriage on the rail, while its interior is accessible through the openings 60, 61.
  • the carriage may be removed, simply by making the guide rail 62 removable, or swingable to release the tracking disk 63 and permit the carriage to be bodily removed in the lateral direction.

  • the supporting forces are created by external conditions when the vehicle body is pressed against the respective support elements and therefore, their sign or direction does not change during travel of the vehicle. Consequently, their optimal number and arrangement should be determined ahead of time.
  • the present invention has a further object, the provision of a method for obtaining an optimal arrangement of guide and supporting elements (i.e., the minimal number required to do the most effective job).
  • the following method is based upon a quasistatistical concept in which the vehicle carriage or body is at least partly captive, restricted or encased in a movable body in a rail system.
  • the known six components of movement namely, the shifting or translatory vectors, and the rotational vectors about the conventional X-, Y- and Z-axes are divided, according to direction or sign into 12 half-components, which are easily displayed in a graphic matrix as seen in the drawings.

  • An example, as in FIG. 19, employs a hollow rail 13 such as seen in FIGS. 1-3 which is provided with a Y-shaped tubular beam branching switch mechanism.
  • the rail system comprises a structurally closed interlocking roller arrangement in which the carriage rides.
  • the tracking disk 19, immediately before the respective switching zone, passes a small electromagnetically operated switch tongue with which it engages and steers it to either the right or left side of the guide line or track. Outside of its operation in the switching zone the tracking disk has no function.
  • each of the two sides or half portions of the body with the assistance of a single commong guide element must again be driven in an interconnected fashion and only movable in the longitudinal X-direction.
  • the use of a single guide element results in the desired security of switching, in this manner.
  • FIG. 19 there is shown a rail and carriage system such as that of FIGS. 1-10 in various phases, steps or positions during its travel in which:
  • Two of the rollers 6 and 7 of the side guide rollers 6-9 define the movement in the i Ydirection.
  • the other two side rollers 8 and 9 prevent the rotation about the Z-axis .Z, :Z).
  • FIG. 20 The illustration of the action of the system of FIG. 19, both in the supporting force diagram SK and the connecting or frictional force matrix I'IK are seen in FIG. 20, in which the vehicle body is diagrammatically indicated undergoing passage through a branching switch, from a situation of travel along the axis.
  • the vehicle passes through three stages or phases A, B and C, in which in the SK diagram the number of forces are shown while in the I-IK diagram the restriction on the half-components are shown, basically derived from the drive forces placed on the carriage by the vehicle to which it is attached.
  • Phase A is the intermediate result in considering the singular guide system in a normal guide rail section. In connection with this portion of the system, eight and not just six SK must be reckoned with. (a b c A, See FIG. 20), since in addition to the support rollers and pressure rollers seen in FIG. 20a, the effect of the guide rollers must be accounted for, see FIGS. 20b and 0. Following Phase A, the effect of the tracking disk 19, when entering the switching zone is added (20s) resultmg in;
  • Phase B in which the sum of all the forces acting on the body are shown.

  • the operation of the tracking disk 19 shifts the carriage in the vicinity of the enlarged portion of the rail to the desired branch direction, for example, as seen in FIG. 19 to the right side. This results in the removal of the two coincident forces (20)) and the vehicle proceeds to;
  • Phase C in the switching zone. In this zone the carriage engages only one-half of the rail sides (i.e., the one toward which it is being branched) and thus reacts only to six of the eight SK vectors possible (B f C).
  • the arrangement of force vectors SK and the restrictions HK matrix is clearly shown.
  • the optimal guide system in the X-direction is illustrated.
  • a SK triple force is the triangular array of three parallel arranged forces when two are exerted in a direction opposite to one of the forces. Such triples are seen in FIG. 21, g and h and have only five HK force value, each.
  • the optimum minimal six SK forces can be obtained with only a minimum of Hk (g h c).
  • Hk g h c
  • the quadruple (a) is sufficient wherein only the support rollers 3 and 4 and downwardly forcing pressures 11 are used.
  • Phase A For side guidance outside of the switching zone only three of the four vertically directed forces necessary to move the vehicle to Phase A, although the four seen in FIG. a are used in order to provide symmetrical operation.
  • Phase C the stronger overlapping and redundant forces seen in Phase B come into play for only a very short time.
  • the carriage can move either to the left or right engaging only the corresponding side wall of the hollow beam rail. For this reason the guide Phase A appears symmetrical to either side of its long axis, and may be thought of as two halves.
  • the tracking disk 19 which comes into function only within the switching zone, and whose working direction effects the selection of the right or left branch, the vehicle may be switched as desired, while being driven in the X-direction only, (Phase C). While for the movement into Phase A all of the functioning guide elements are preferably cylindrical rollers, in the switch zone the disk 19 which functions as an additional switchable element, is basically nothing more than a single selecting element in the form of a rotatable crown, rim, ring or cam. As soon as the vehicle passes the switching zone the hollow rail assumes its normal cross section and the additional function of the disk 19 can be dispensed with and the guide made to follow the normal pattern of Phase A.
  • the described optimum solution rests on the fact that during passage through the rail branch sections, the forces acting to turn out the carriage are reduced to an irreducible minimum, independent of the driving or other forces.
  • the forces are grouped into two groups of vectors acting in planes perpendicular to each other (substantially vertical and horizontal planes) and in each group the vectors are either arranged in triple or quadruple fashion. At least one being in triple.
  • the number of supporting forces and therey also of the supporting elements, in Phase C corresponds to the theoretical minimum, and that in Phases A and B only so many overlapping or redundant elements and forces are provided which would insure the desired shoving and shifting of the vehicle laterally or transversely on passing through the branching mechanism, in either direction.
  • FIGS. 22 and 23 show the application of the supporting force system to the entire vehicle, such as a taxicab. As in the prior example, this example can be illustrated with the help of a half-component diagram and matrix.
  • FIG. 22 shows a taxicab or mini-bus body 50 having two wheels 52.
  • the body is provided with seats, etc., and may be self-propelled.
  • the wheels 52 carry the load of the vehicle.
  • the body is connected to a guide rail system, such as that described in FIGS. 1-3.
  • FIG. 23 the forces exerted on this system are analyzed and are set forth in the given matrices. It will be seen by this example that the forces act on the vehicle as well as on the railed carriage. In the given direction of travel of the vehicle, frictional forces prevail (undulating, up and down; sideways, shifting in the X and Y positive and negative directions,) while in the positive Z- direction, exclusively, the force of gravity exists. This latter force is seen by the dots in the appropriate field.
  • a very important advantage of the present invention is the provision of a secure quiet and soft guidance system, without latter sway or movement when passing through the switch mechanism, even at full speed. Further advantage comes about by permitting very short switching times, of about one-tenth of a second. It is also to provide branching switches between two succeeding vehicle units travelling at speeds as high as 60 kilometer per hour. Even if the switch should misswitch, during passage of the vehicle, the rail carriage is neither derailed or stopped. Combining or merging switches do not need movable parts and therefore no actuation is necessary. The vehicle may follow even closer and at higher speeds. The theoretical optimum criteria discussed above otherwise fits in with such merging switches.
  • the present invention may be employed in various rail systems.
  • the cabin may be resiliently but not steerably connected to the rail carriage. It follows the rail system in a tow or drag line and forms together with its pivot pin a three pointed support.

  • the optimum solution that is the number of the supporting forces and therefore, the supporting elements not only for the rail carriage but also for the entire vehicle should not be greater than is necessary under the given conditions, subject to the aforedescribed method of resolution.
  • the present invention has the following advantages,
  • the moveable elements on the carriage and on the switch are small and simple. They only make small movements and are therefore, easily and swiftly positioned, in fractions of seconds. It is not necessary to insist on several movable rollers, tongues, etc., or steerable support rollers. Even at full speed and small succeeding distances, switching vehicle is possible.
  • the actuation of the track selection means can be either on the switch or on the vehicle. It may be mechanical, hydraulic, pneumatic or electrical, etc. Stop and lock means may be employed to lock the switch mechanism, such as the tongue, to insure switching in only one direction.
  • the carriage is driven in each driving position in interlocked manner and enclosed in the rail. It is therefore, especially suitable for single pole trolley guide rail and power systems, on which upward forces are exerted.
