Definitions

  • the invention relates to a four-axle bogie for low-floor wagons, with two H-shaped frames each carrying two sets of wheels, which are connected in an articulated manner to a main beam forming a crossbeam and receiving the rotary bearing of the bogie.
  • the AT-A-305 360 shows a four-axle bogie with two H-shaped frames for two axles each and a main beam with which the H-frames are articulated.
  • the main frame or main beam is H-shaped and, with the ends of its legs, articulates around the crossbars of the H-frame.
  • the aim of the invention is to achieve a uniform distribution of the axle loads even on poor track and thus good running properties; Furthermore, the bogie according to the invention with a mechanical or hydraulic compensation device should also be suitable for extreme ramp journeys and for ferry operation.
  • the carriage structure is mounted on the crossbar by means of a plunger rigidly attached to it, in that the ends of the longitudinal beams of the H-shaped frames facing the crossbar are each directly or about a horizontal axis with the interposition of a two-armed lever are pivotally articulated on the crossbeam and that the vehicle body is supported on each side member by means of a suspension spring.
  • axles of the two biaxial bogie parts are each braked by a common, balanced braking system, which ensures uniform application of the braking force.
  • the articulation of the two-axle bogie parts on the crossbeams each in a separate mounting enables the two bogie parts to change their position without force even when the track is in the most unfavorable position, especially when driving on extreme ramps and especially when entering from a straight line into the slope, thereby preventing vertical Forces are transmitted from one bogie part to the other bogie part.
  • a rotation of the crossbar is made possible by the plunger, which is designed to be pivotable on all sides in the known manner in the manner of a ball joint. This arrangement avoids additional axle pressure changes that can arise from the mutual change in position of the two bogie parts. This is an essential technical effect compared to DE-A-1 605 094, in which the bogie part is supported by a common bolt.
  • the design of the bogie according to the invention further ensures that the driving properties of the bogie are not impaired even with different braking forces in both bogie parts and any unevenness in the track.
  • the abutments of the suspension springs located one behind the other in the direction of travel are e.g. connected as a pull or push rod compensation device.
  • the design of the compensating device as a pull rod has the advantage that it does not have to be dimensioned as strongly as a push rod, as a result of which material and weight can be saved.
  • the abutments could also be designed in a known manner as pistons of hydraulic cylinders which are connected by an equalizing line.
  • DE-G-439 045 shows a base frame for railway carriages, in which one end of each two axles of a pair of axles connected by their other ends to a longitudinal compensation lever are connected to one another by parts in such a way that an additional load on the egg NEN spring is evenly distributed on both springs.
  • AT-A-325 663 discloses a device for balancing the axle pressures on a chassis of a rail vehicle with two alternately pressurized pneumatic or hydraulic pressure elements for transmitting a substantially downward balancing force to the front or rear end of the chassis, the two pressure elements are each connected via a pressure line.
  • DE-A-2 317 562 shows a rail bogie with four wheel sets, two of which are supported on both sides of the vehicle by axle springs connected to one another by longitudinal compensation levers on the chassis frame, the longitudinal compensation levers on the vehicle frame being vertically movable and compensated by a hydraulic system on one vehicle side .
  • the main cross member of the bogie is designated 1 and consists of a box-like support member or cross bar 2, which is provided in the middle with a recess 3 for receiving a storage, not shown, for the plunger rigidly attached to the car body.
  • This plunger bearing essentially consists of a sleeve into which the plunger fits axially displaceably, a spherical thickening which sits on the sleeve and a holder which receives this spherical thickening and is fastened in the recess 3.
  • This storage can be in an oil bath and is therefore maintenance-free.
  • the main beam 1 can therefore axially, i.e.. vertical, move, twist and tilt in any direction.
  • two extensions 4 rigidly connected to or extending from this are provided at each end of the box-like support part 2, on which the H-shaped frames 5 on the main Cross member 1 facing ends of their longitudinal parts 8 are pivoted about horizontal axes 6.
  • These frames 5 consist of a cross member 7 designed as a box girder and the longitudinal parts 8, which are each provided with two recesses 9 for receiving the axle journals 10 of the wheel sets 11 - not shown.
  • a pot-like, open top recess 12 is provided at the transition point between the transverse part 7 and each longitudinal part 8, the central plane of which is transverse to the direction of travel preferably coinciding with the longitudinal central plane of the transverse part 7;
  • the springs to be described, including supports, are located in these recesses. Due to their shape and their dimensions, the H-shaped frames 5 have a certain degree of torsion, which is deliberately used in the inventive bogie.
  • each bogie in order to cushion the car structure 14, which is only indicated.
  • These are designed as helical springs and can preferably have a non-linear or progressive overall characteristic curve in the usual manner by arranging two helical springs with different characteristics and different lengths, one inside the other or one behind the other, if necessary by interposing a blocker pot.
  • the top of each spring 15 is provided with a support plate 16 which carries the underside of the carriage structure 14 via a sliding coating 17 attached to it.
  • a double-armed lever 4 ' is provided at least at one end of the main cross member 1, which is articulated to the support part 2 or on the latter about a longitudinal axis 2 located in the longitudinal center plane of the main cross member 1 'is pivotally mounted.
  • the longitudinal parts 8 of the transverse parts 7 are pivotally mounted via silent blocks.
  • the springs 15 are each provided on their underside with a support plate or an abutment 19 which in turn rests on the free end of a support lever 20.
  • the end of this support lever is forked and embraced the bolt 18.
  • the ends of the support levers 20 have curved tops 21 so that they can roll on the underside of the support plate 19 during their pivoting movements without any friction.
  • the support levers 20 are each attached to a short shaft 22, which is rotatably mounted in the two walls of the pot-like recess 12.
  • the shafts attached to both sides of each H-shaped frame 5 have a common horizontal axis 22 ', which runs in a central vertical plane of the carrier 7, which preferably has the same distance from the axes of the two wheel sets 11 of the H-shaped frame 5 (cf. especially Figure 4 left).
  • One end of each shaft 22 is extended beyond the outer wall of the longitudinal part 8 and carries a compensating lever 23 there.
  • the two compensating levers 23 located on the same bogie side are inclined towards one another in the drawing and are coupled to one another by a compensating device. However, they can also preferably be arranged perpendicularly and parallel to one another.
  • this compensating device consists of a pull rod 24, which is connected at its ends to the compensating lever 23 in an articulated manner via bolts 25.
  • a vibration damper can be placed between the tie rods 24 or one of the two compensating levers 23 and the side wall of the bogie;
  • these vibration dampers lying essentially horizontally, are each articulated between the tie rods 24 and the ends of the main cross member 1.
  • the suspension springs 15 are not arranged as shown in FIGS. 4 and 5, between the lever 23 and the outer one, but as shown in FIG. 6, the adjacent inner wheel set 11, the levers 23 being able to diverge upwards. This construction reduces the distance between the pivot pin and the slide plate, which reduces the restoring force in the slide plate support.
  • FIG. 8 shows that position of the bogie in which the first axis of the bogie has increased by the amount a 3 and its last axis has just reached the start A of ramp B. It can be clearly seen that, because the left H-frame is also raised, the compensating levers 23 have pivoted a little further clockwise. However, it can also be seen that the lengths of the springs 15 'and 15 "have remained the same. The inclination of the support part 2 with respect to the horizontal when the ramp B is approached (cf.
  • Each compensating lever is connected to the rod of a piston via a link, which is preferably subjected to pressure, which can move in a substantially horizontal cylinder attached to the H-shaped support.
  • the cylinders are closed at one end and filled with a liquid (hydraulic oil and the like).
  • the two cylinders on each side of the bogie are connected by a pressure-resistant line.
  • the support plate 19 is also the possibility of designing the support plate 19 as a piston of a cylinder and of connecting both pairs of cylinders lying at right angles to the direction of travel with an oil pressure line, the mechanical compensation device being dispensed with.
  • a throttling point for example in the form of a valve, can be provided in the pressure line connecting the two cylinders in order to dampen vibrations which can occur on poor tracks.
