Definitions

  • the invention concerns a bogie arrangement for railway vehicles, which said bogie arrangement comprises at least two bogies provided with wheels, said bogies consisting of two pivotable bogie frame parts that are linked together and said bogies being coupled to each other mechanically and to the railway vehicle by means of the suspension.
  • the bogie constructions that are used at present under railway vehicles have, almost without exception, such a construction that the bogie frame is rigid and suspended on the frame of the railway vehicle, such as a locomotive, wagon, coach, or equivalent, by means of a two-stage suspension.
  • a rigid bogie frame involves several drawbacks, of which one significant drawback is manifested in particular when running in curves.
  • the wheel sets in the bogie cannot be steered in the curve radially, but the wheels of a wheel set are so to say wedged against the rail, with resulting intensive wear of the wheels and the rails. Owing to such a wedging effect, part of the tractive effort of the locomotive is "lost" in the resistance in the curves.
  • two-stage suspension means that the wheel sets of the bogie are first suspended by means of axle suspension on an inter­mediate frame or cage, which is again suspended by means of a bogie suspension on the frame of the railway vehicle.
  • a significant drawback related to this is the complicated construction, for such a bogie construction includes a very high number of components. This is why the con­struction is quite expensive.
  • a second difficulty in such a construction is, likewise owing to the complicated construction, how to arrange the coupling of the springs.
  • German Patents 3,213,804, 3,221,755, and 3,235,692 and the EP Patent 0,165,752 suggest different bogie constructions, in which the bogie frame is divided in two parts and linked at the middle so that the wheel sets should be able to be steered substantially radially in curves. All of these bogie constructions, however, involve several drawbacks, for which reason the bogie constructions in accordance with the said patents have not become commonly used in railway rolling stock.
  • the construction in accordance with the German Patent 3,213,804 includes a separate bogie bolster, which is suspended on the frame of the vehicle.
  • the wheel sets are suspended individually on the said bogie bolster.
  • the con­struction in accordance with the said patent is provided with two-stage suspension.
  • the said construc­tion is highly unfavourable in the respect that, owing to the geometry of the construction, the dynamic reaction forces are transmitted substantially directly to the frame of the upper structure, i.e. of the wagon, coach, locomotive,or equivalent.
  • the construction is also quite unstable.
  • the German Patent 3,221,755 the system of articulated joints in the bogie has been accomplished by using a highly complicated cage in the bogie. The cost of manufacture of such a bogie is very high.
  • the object of the present invention is to solve the problems described above and to provide a substantial improvement over the existing bogie construc­tions and to provide radial steering of the wheel sets in the bogie and to reduce the number of structural com­ponents, i.e. to omit the traditional bogie cage.
  • the bogie arrangement in accord­ance with the invention is mainly characterized in that the first part and the second part of the bogie frame of each bogie are coupled to each other so that they can pivot both relative the longitudinal axis of the bogie and relative the vertical centre axis of the bogie, and that the bogie is suspended by means of a single-stage suspension directly on the frame of the railway vehicle, each bogie included in the bogie arrangement being con­nected to the other bogie or bogies in the arrangement by means of positive steering so that the axles of the wheel sets in each bogie are arranged to be steered in curves substantially radially irrespective of the curve radius.
  • the linkage between the wheel sets carries out the duties of a con­ventional bogie cage, i.e. the turning of the wheels in curves.
  • the conventional bogie suspension i.e. the suspension between the bogie cage and the vehicle frame, is substituted for by making the springs communicate with each other at each side.
  • the bogie suspension has permitted "pitching" of the bogie relative the frame, which property is needed, e.g., when passing over the top of a hill and, in a corresponding way, in a valley.
  • the bogie has obtained the same property.
  • the communication between the springs and the linkage between the parts of the bogie frame so that they are pivotable relative the longitudinal centre axis jointly permit adaptation of the wheels in the wheel sets in accordance with the bankings in curves.
  • the frame of the bogie 10 consists of two parts so that it comprises a first part 11 and a second part 12 of the bogie frame, which said parts are interconnected by means of articu­lated joints.
  • the parts 11 and 12 of the bogie frame are preferably cast pieces, and these parts 11 and 12 of the bogie frame act as frames for the wheel sets of the bogie 10 so that the first part 11 of the bogie frame includes the first wheel set, provided with the first wheels 13 mounted on the first axle 15, and correspond­ingly the second part 12 of the bogie frame includes the second wheel set, which is provided with the second wheels 14 mounted on the second axle 16.
  • the parts 11 and 12 of the bogie frame are connected to each other fully “torsionally loosely” by means of an articulated joint 21 so that the parts 11 and 12 of the bogie frame can pivot relative each other around the longitudinal and horizontal centre axis of the bogie 10 as well as turn relative each other around a vertical centre axis of the bogie.
  • the joint 21 is a joint turnable in all directions, such as a ball joint, rubber joint, or equivalent, whereby the parts 11 and 12 of the bogie frame can also turn in all directions relative each other.
  • the fastening lugs 22 and 23 are preferably formed as parts cast integrally with the bogie frame parts 11 and 12.
  • the bogie frame parts 11 and 12 are interconnected in the way described above "torsionally loosely", it has been additionally necessary to inter­connect the bogie frame parts 11 and 12 by means of a stabilizer rod system 25, which prevents bending-down or bending-up of the bogie frame parts 11 and 12 relative the articulated joint 21.
  • the bogie frame parts 11 and 12 are firstly provided with fastening lugs 26 and 27, which are fitted on the centre line of the bogie 10.
  • the stabilizer rod system 25 itself comprises a horizontal rod 28, which is fitted inside a sleeve 29, whereat the said rod 28 and sleeve 29 are supported at their ends on the fasten­ing lugs 26 and 27.
  • the rod 28 receives tensile strains, and it prevents turning of the bogie frame parts 11 and 12 in relation to the horizontal transverse axis around the articulated joint 21 so that the said joint 21 rises during this turning movement.
  • the sleeve 29 is fitted so as to receive compression strains, whereby it again prevents turning of the bogie frame parts 11 and 12 around the articulated joint 21 in the opposite direction.
  • the rod 28 and the sleeve 29 are supported at their ends on the fastening lugs 26 and 27 by the intermediate of elastic pieces 30, whereby the fastening between the stabilizer rod system 25 and the bogie frame parts 11 and 12 is not fully rigid.
  • the stabilizer rod system 25 may be arranged relatively resilient, because strains derived from traction forces or braking forces are not transmitted to it. This is due to the fact that the bogie 10 has been formed symmetric relative the articulated joint 21, whereby, owing to this symmetry and the dimensioning of the bogie, the strains derived on the bogie frame parts 11 and 12 from traction forces and braking forces sub­stantially neutralize each other. Another important reason for the resilience of the stabilizer rod system 25 is that, owing to said resilience, any strains and loads caused by impacts are not transferred from one part of the bogie frame to the other.
  • the bogie frame parts 11 and 12 can turn relative each other around the articulated joint 21 fully freely, in stead of a ball joint or rubber joint, it is also possible to use some other sort of a fully freely turnable joint which pro­duces the same effect.
  • the bogie 10 in accordance with the invention a single-stage suspension is used.
  • the bogie 10 is suspended directly on the frame of the rail vehicle without a conventional intermediate frame arrangement.
  • the first part 11 of the bogie frame is provided with the first springs 17, and correspond­ingly the second part 12 of the bogie frame is provided with the second springs 18, which are, thus, directly connected to the frame of the rail vehicle.
  • the springs 17 and 18 are fitted directly above the wheel-set axles 15 and 16, respectively, whereby it has been possible to reduce the bending strains derived from the suspension on the bogie frame parts 11 and 12 substantially, whereby a reduced quantity of material has been adequate in the manufacture of the bogie frame parts 11,12.
  • the springs 17 and 18 are advantageously gas-hydraulic springs, and they communicate with each other in the way shown in Fig. 2, so that the springs 17 and 18 on the bogie frame parts 11 and 12 at each side of the bogie 10 are connected to each other, e.g., by means of hydraulic pipe systems 31 and 32 and necessary throttles 35 or equivalent.
  • the hydraulic fluid in the springs 17 and 18 flows along the said pipe systems 31 and 32 from one spring into the other so that, at each side of the bogie 10, part of the spring force or load is arranged to be passed from the spring 17 or 18 with higher load to the spring 18 or 17 with lower load.
  • springs of some other type whereat their inter­connection is, however, taken care of in a corresponding way.
  • the bogies are coupled and fixed so that, when running in curves, the wheel sets of each bogie 10,10a are steered so that the wheel set axles 15,16,15a,16a are steered in curves fully radially.
  • the steering of the wheel sets is arranged so that, in the bogie arrange­ment, two subsequent bogies 10,10a are interconnected by means of a connecting rod 40, as is shown in the figures in the drawing.
  • the connecting rod 40 is linked with each bogie 10,10a by means of an articulated joint 41,41a, which connects the connecting rod 40 to the first part 11,11a of the bogie frame of each bogie 10,10a so that the articulated joint 41,41a between the connecting rod 40 and the first part 11,11a of the bogie frame is placed at the side of the connecting rod 40 in relation to the corresponding wheel-set axle 15,15a.
  • the connec­ting rod 40 is, however, extended beyond the said artic­ulated joint 41,41a to the other side of the wheel-set axle 15,15a, including an extension 42,42a of the con­necting rod, which said extension 42,42a is linked by means of an articulated joint 44,44a with support rods 45,45a, which are, at their opposite end, linked with the second part 12,12a of the bogie frame by means of an articulated joint 46,46a.
  • the connecting rod 40 pivots relative the articulated joint 41 between the connecting rod and the first part 11 of the bogie frame so that the extension 42 of the connecting rod 40 and the articulated joint 44 placed at its end turn towards the outside curve and, by the intermediate of the support rods 45, turn the second part 12 of the bogie frame, which is connected to the first part 11 of the bogie frame by the intermediate of the articulated joint 21, relative the first part 11 of the bogie frame so that, with a correct dimensioning of the articulated joints and the rods, the axles 15 and 16 of the wheel sets in the bogie 10 become positioned fully correctly, i.e. fully radially in a curve.
  • the axles 15a and 16a of the wheel sets in the bogie 10a turn in a corresponding way, because they are connected to the connecting rod 40 exactly in the same way as the bogie 10 placed at the opposite end of the rod 40.
  • the transfer of tractive force and braking forces between the rail vehicle and the bogies 10 and 10a is arranged, e.g., so that the connecting rod 40 is provided with a support member 43, from which the said forces are transferred to the frame of the rail vehicle by means of a separate linkage.
  • the bogie arrangement in accordance with the in­vention and the bogies included in the bogie arrangement are characterized by the following specific features. Firstly, single-stage suspension of the bogies 10,10a, i.e. the circumstance that the bogies 10,10a are sus­pended directly on the frame of the rail vehicle without an intermediate frame and a secondary suspension. Secondly, the parts 11 and 12 of the bogie frame are interconnected fully “torsionally loosely", whereat this interconnection of the parts of the bogie frame together with the suspension connection described above permit the wheel sets in the bogies 10,10a to be steered fully freely in the way required by the curve radius and, e.g., by the curve bankings.
  • the bogies 10,10a are interconnected by a connecting rod 40 so that the wheel sets in the bogies are arranged to be positioned in curves fully radially under positive control.
  • the radial control operates in the way described above also when rigid axles are used, but the advantages of the invention are manifested most clearly when the wheels in each wheel set are arranged so as to revolve independent­ly from each other.
