Definitions
- the present invention relates to a device for guiding and supporting a railway vehicle, consisting of a bogie with independent wheels comprising a cross member secured to a body of the vehicle so as to be perpendicular to the vertical plane containing the longitudinal axis of the vehicle in the vicinity of one end of this body thus ⁇ ue two side members provided with at least one wheel and, in the longitudinal direction, on articulation means carried by the cross member on either side of the above-mentioned vertical plane, so as to allow the wheels carried by the side rails to follow the curvatures and to cross the unevenness of the track.
- European patent n ° 0 060 000 describes a lifting and guiding device for a railway vehicle, fitted with at least four wheels mounted on a support intended to be secured to the body of a vehicle, in the vicinity of a end of this case.
- This device consists of a cross member held perpendicular to the vertical plane containing the longitudinal axis of the vehicle and two longitudinal members arranged, in the service position, in the longitudinal direction of the body, on either side of the above vertical plane. .
- These beams are connected to each other by means of a rod mounted on ball joints. They are articulated to the common crosspiece by pivots capable of taking a certain inclination in a substantially vertical plane.
- These pivots are connected to each other by ball joints and a lifter secured to the cross member by a pivot perpendicular to the plane formed by the cross member and the longitudinal axis of the vehicle.
- the longitudinal members pivot relative to the cross member around substantially vertical pivots and form the opposite sides of a deformable parallelogram, while the cross member remains perpendicular to the longitudinal axis of the vehicle body.
- the rigidity of the beams prevents the wheels carried by the same beam, and leaning on the same line of rail, to orient themselves simultaneously tangentially to said rail.
- the present invention aims to remedy this drawback. It relates to a device for guiding and supporting a railway vehicle, consisting of a bogie with independent wheels capable of pivoting about a vertical axis and of moving independently in a vertical plane on each of the rail lines.
- the bogie includes a cross member secured to a body of the vehicle so as to be perpendicular to the vertical plane containing the longitudinal axis of the vehicle in the vicinity of one end of this body, thus ⁇ ue two side members provided with at least one wheel and, in the longitudinal direction, on articulation means carried by the cross member on either side of the aforesaid vertical plane, so as to allow the wheels carried by the side members to follow the curvatures and to cross the unevenness of the track.
- This device is essentially characterized in that the longitudinal members comprise an articulation and each consist of a longitudinal structural element articulated to the cross member and extended by a directional arm articulated to the longitudinal structural element around a substantially vertical pivot and provided at a free end with a guide wheel.
- each spar has an appendage extending inwardly of the bogie in a transverse direction substantially perpendicular to that of the arm and having articulations on les ⁇ uelles is fixed a spacer.
- Each directional arm advantageously carries in the vicinity of its free end an appendage extending towards the inside of the bogie in a transverse direction, on the rod is fixed a rod integral with the above-mentioned spacer.
- the distance between the fixing points of the spacer to the spar is advantageously determined as a function of the wheelbase, the track width and the position of the articulations of the structural members to the cross member and of the directional arm relative to the structural element.
- the ratio of the distance between the plane of the guide wheel and the articulation means ⁇ ui secures the rod to the appendage of the directional arm and that between said plane of the guide wheel and the articulation means ⁇ ui secures the rod to the spacer, is chosen in such a way that the plane of the guide wheel is substantially tangent to the line of the rail so as to favorably influence the bogie inscription in the curve.
- the rods are connected to the appendages of the arms by means of ball joints and to the spacer by means of pivots.
- An advantage of the invention lies in the fact that a pair of wheels of the device according to the invention leaning on the same line of rail, can be oriented simultaneously tangentially to the curvature of the track
- the self-centering characteristics of the guidance and lift device are not reduced because the directional arms and the longitudinal members are maintained in vertical planes strictly parallel between them two by two.
- the speeds of rotation of each of the wheels, driving or not, are independent.
- FIG. 1 is a plan view of a preferred embodiment of the device according to the invention, on a straight path;
- FIG. 1 is a side elevational view of the device illustrated in Figure 1;
- Figure 3 is a plan view similar to that of Figure 1 showing the device according to the invention being part of a curve of a railway track;
- FIG. 4 is a detailed side elevation view of the articulation of the directional arm to the support beam in the side members.
- the same reference signs designate the identi ⁇ ues or similar elements.
- the guidance and lift device is a bogie with independent wheels intended to carry a body or a part of body 2 of the above railway vehicle.
- the floor is shown in phantom in Figures 1 and 2 above, in the vicinity of one end of this box 2.
- This device 1 comprises a cross member 3 arranged perpen icularly in the vertical plane containing the longitudinal axis XX 'of the box 2 and two longitudinal members 4 which, in the service position of the device, extend in the longitudinal direction of the body 2, on either side of the vertical plane containing the longitudinal axis XX ′.
- Each beam 4 is made up of two parts hinged together. The first of these parts is a longitudinal frame element 5 carrying a wheel 6, possibly driving.
- This longitudinal frame element 5 is extended by a directional arm 7 articulated to the longitudinal frame element 5 around a pivot 8 substantially vertical.
- the directional arm 7 also carries at least one wheel 9. Each spar therefore carries a pair of wheels 6, 9 intended to follow the same line of rail, shown diagrammatically by lines 10.
- the longitudinal frame element 5 preferably carries wheels 6 - of large diameter which constitute carrying wheels possibly motorized. These wheels 6 are mounted on the outside in the vicinity of one end of the beam 4.
- the directional arms 7 will preferably carry small diameter wheels which are guide wheels 9. These guide wheels 9 are mounted in a fork 11 provided at the free end of the directional arms 7.
- articulation means 12 carrying the cross member 3 so as to be able, on the one hand, to pivot in the direction of the arrows Y ( Figure 1), and on the other hand, to tilt in the direction arrows Z ( Figure 2).
- These articulation means can be pivots 13 carried by lateral bosses not shown. These pivots 13 are capable of taking a certain inclination in a substantially vertical plane around axes 14 parallel to the longitudinal axis of the cross-member 3, so that the longitudinal members 4, that is to say the longitudinal frame elements 5 and the directional arms 7 can tilt in the direction of the arrows Z.
- Each longitudinal structural element 5 has a first appendage 15 which extends towards the inside of the bogie, in a transverse direction substantially perpendicular to that of a part of the spar 4 joining the pivot 13 to the pivot 8. According to the invention, these appendages 15 are used for fixing by means of an articulation 16 of a spacer 17 connecting the longitudinal members 4 to one another.
- Each directional arm 7 carries in the vicinity of its free end a second appendage 18 which extends towards the inside of the bogie in one direction perpendicular to the arm 7.
- this second appendage 18 is articulated using a ball joint 20, a rod 19 secured to the spacer 17 using a ball joint 21.
- the rods 19 and the spacer 17 form articulated quadrilaterals, which secure the directional arms 7 to the side members 4.
- the guide wheels 9 separate the directional arms 7 to the left or the right in order to follow the curvatures of the rail 10 while being oriented tangentially to said rail 10. These deviations of the directional arms 7 cause a movement for pivoting the longitudinal frame elements 5 relative to the cross-member 3 around the substantially vertical pivots 13.
- pivots 13 can moreover incline in a substantially vertical plane around axes 14 parallel to the longitudinal axis of the cross-member 3, so that the longitudinal structural elements 5 and the directional arms 7 can themselves 'tilt in the direction of the arrows Z and ensure permanent contact between the wheels 6, 9 and the track, regardless of the level variations of the rail lines 10, as described in European Patent No. c 0 060 000.
- the spacer 17 takes a horizontal position, when the rails 10 are at the same level. This spacer 17 is substantially parallel to cross member 12 in the rectilinear paths and then extends perpendicularly to the two longitudinal members 4.
- the longitudinal members 4 constitute levers which can both pivot and tilt relative to the cross member 3 under the action of the directional arms 7.
- the pivots 13 around which the longitudinal members 4 can pivot are articulated on the one hand around axes 14 integral with the cross-member 3 by ball joints with a lifter 22.
- This lifter 22 which has a vertical pivot 0 23 secured to the cross member 3, maintains the axes of the pivots 13 of the side members 4 in substantially vertical planes while allowing them to tilt in these planes.
- the crosspiece 3 is provided with a lateral boss 23 yes serves as a fulcrum for means for connecting the cross-member 3 to. floor of the body 2.
- These means comprise, in a known manner, a coil spring 24, one end of which bears on the lateral boss 23 and the opposite end of which bears on the floor of the body 2.
- a rod 25 provided with the one of its ends of a first ball joint 26 secured to the cross member .3 and at its opposite end of a second ball joint 27, secured to a tab 28 fixed to the floor of the body 2, keeps the cross member substantially perpendicular to the longitudinal axis of the body, while allowing lateral movement in the direction of the arrows W of the cross member 3 relative to the body 2. This lateral movement is limited. Stop pieces carried by the cross member 3 and by the body 2 limit the lateral displacement of the cross member and limit the compression of the coil springs 24.
- Each large diameter wheel 6 can be individually connected to a one-piece motor-reducer assembly 29 secured to the longitudinal frame element 5, the wheel being wedged on the output shaft 30 of this assembly.
- the guidance and lift device which is the subject of the present invention can be provided with auxiliary equipment, such as motors, disc brakes, brakes with magnetic pad on rails, anti-derailment stop, etc.
- a directional arm 7 and a longitudinal frame element 5 secured to one another by the articulated quadrilateral allows the device according to the invention to attack very sharp turns. tight since it allows the wheels to orient themselves tangentially to the curvature of the track. This avoids the sliding of the beads 31 against the rail 10.
- the adjustment of the length of the rods 19 and the choice of their point of attachment to the appendages 18 of the directional arms 7 and on the spacer 17 makes it possible to preset a perfect parallelism of the wheels guide 9 or compensate for wear by a certain degree of pinching.
- This device ensures self-centering of the vehicle thanks to a frustoconical shape of the tires 34 of the wheels 6, 9.
- This device also makes it possible to further preserve the numerous advantages already mentioned in European patent n ° 0 060 000. It is of low weight. Its reduced size makes it possible to reduce the height of the vehicle floor, relative to the track, thereby improving the accessibility of said vehicle and reducing the size.
- FIG. 4 A longitudinal section view of the pivot 8 is shown in FIG. 4.
- the pivot 8 rests on two tapered roller bearings 35, the housings 36 of which are mounted on the longitudinal frame elements
- the device kinematically deforms without showing any stresses or restoring efforts.
- the distribution of the loads between the wheels 6, 9 is practically independent of the external elements such as the cant, the track unevenness and the body movements of the vehicle. Dynamic stability is also improved and the risk of derailment is 12
- the beams 4 may have a shape different from that shown in Figures 1, 3 and 4 and be for example rectilinear.
- the wheels 6, 9 are then mounted on the same side of the beam 4.
- the side members 4 can be articulated to the cross member 3 by a ball joint not shown carried by said cross member 3.
- the side members 4 must then be held in place by a ball joint 32 fixed to the lifter 22, which is integral with the cross member 3 by a substantially vertical pivot 23 in the operating position of the device or by a third ball joint.
