Definitions
- the invention relates to a rail vehicle with a grinding car and a two-axle generator car articulated to it according to the preamble of the claims. It is used in particular to move a scraper which can be used universally on common rail networks.
- Standard components especially undercarriages, have the disadvantage that they do not always offer enough space for system-important assemblies of the special machines and thus impair their performance.
- the shortcomings indicated are intended to be remedied by the invention.
- a rail vehicle for a rail grinding machine is to be created, the coupling mechanism of which enables the actual power module to function exactly, even in the case of narrow radii, without impairments.
- the above object is achieved by the characterizing features of the first claim.
- the invention enables a separation of the tensile and compressive forces existing between the generator car, the grinding car and the steering forces.
- a rod is advantageously mounted in a guide piece in such a way that it can incline with and / or in the guide piece in two mutually perpendicular directions and can move parallel to its longitudinal direction.
- the guide piece is located at the free end of a drawbar at least approximately half the length of the rod between the cars. This is particularly the case when the wheel axles of the grinding carriage and the generator carriage, which are adjacent to the coupling, are each pivotably arranged about an at least approximately vertical axis and the drawbar provided with the guide piece is assigned to both wheel axles. Then both guide pieces can not be arranged exactly half the distance of the rod for reasons of space.
- the drawbar is advantageously designed to be trapezoidal for reasons of stability and is articulated with its longer parallel side to the wheel axle or its bearing body, which can be pivoted about the at least approximately vertical axis, and provided with the guide piece on its shorter parallel side, in the middle thereof.
- the guide piece which is preferably provided with a guide opening, is attached to the drawbar in such a way that it can be pivoted about an axis which lies in a pivot plane of the drawbar which is directed at right angles to the pivotable wheel axis, and that the guide opening parallel to the pivot axis of the guide piece is significantly larger than the dimension of the rod in that direction.
- the rod has enough space to change its inclination in this direction.
- guide bodies can be provided, at least on the inner surfaces of the guide opening lying parallel to the pivot axis of the drawbar, which preferably consist of a softer material than the rod to be guided and can be attached in a rolling manner.
- Another option one of ⁇ wangsl äften "free sliding of the bar to ensure imported Fuhrungsstuck, the articulating guide piece at the corresponding drawbar end.
- the invention in the present case is also directed to the coupling of a grinding car to a generator car, it should nevertheless encompass all cases of special rail vehicles in which two cars are coupled to one another and have to be driven in a defined manner primarily over narrow radii.
- Fig. 1 shows a special rail vehicle according to the invention in view
- Fig. 2 shows the top view of the invention
- a special rail vehicle 10 consists of a grinding carriage 11 and a generator carriage 12, both of which are connected to one another with the aid of coupling means 13.
- the special rail vehicle 10 is intended for the maintenance of rail surfaces; with it, the longitudinal and transverse profile of rails 26 with a required surface roughness may be restored.
- the grinding carriage 11 has a chassis frame 14 on which wheel axles 16 and 17 for wheel pairs 18, 19 are mounted at a distance 1] from one another and on which a bridge-like, bending and torsion-resistant support frame 20 for grinding modules 21 assigned to each rail of a track 26, 22, 23 and 47, 48, 49 is attached.
- a bridge-like, bending and torsion-resistant support frame 20 for grinding modules 21 assigned to each rail of a track 26, 22, 23 and 47, 48, 49 is attached.
- stops 31 are provided for the wheel axle 17 to define a minimally movable rail radius.
- a simple steering axis 24 with a pair of wheels 25 can be pivoted in the vertical direction (pitch), which, for example, via swivel arms 27 and fluid (hydraulic or pneumatic) cylinders, not shown pressed onto the rails 26 or is lifted from these.
- pitch the vertical direction
- lockable differentials 30 are provided for each axis 16, for movement compensation.
- the wheel axles 16, 17 are pivotally mounted about vertical axes D, B.
- the wheel axles 16, 17 are each equipped with a ball joint ring 33, 34 which enables a direct yaw movement of the wheel axles mentioned.
- the wheel axle 17 is pivoted, i.e. H. it can perform pendulum movements in the direction of travel and against the direction of travel.
- the steering of the axles 16, 17 is necessary because, owing to the structurally required large wheel spacing lj (approx. 4500 mm) in arcs with a radius of less than approx. 40 m, a secant cut of the wheel spacing with respect to the circular arc of the rails 26 would become too large.
- the arrangement of the ball joint ring 33, 34 enables considerable savings in installation space (more than twice), which can then be used for other purposes, e.g. B. for the installation of the grinding modules 21, 22, 23 and 47, 48, 49.
- the generator carriage 12 has a horizontal truss square frame 35, on which wheel axles 36, 37 are not pivotably mounted at a distance I 2 with wheel pairs 38, 39.
- the distance between the wheels of each wheel pair 38, 39 can be changed to adapt to the track width.
- Lockable differentials 40 are used to compensate for the different rotations of the wheels 38 and 39, in particular when the generator carriage 12 is cornering.
- At least one generator, preferably two generators 54, is located in the generator carriage 12, and the grinding modules 21, 22, 23 and 47, 48 , 49 their possibly existing additional units and the driver's cab 29 are supplied with electrical energy. Grinding modules can also be provided on the generator carriage 12.
- the wheel axles 36, 37 can also be arranged pivotably about vertical axes A, C arranged at right angles to them.
- the coupling means 13 between the grinding carriage 11 and the generator carriage 12 consist, as can be seen in FIGS. 2 and 4, of a pull and push rod 15 articulated on both carriages 11 and 12 and a trapezoidal drawbar 28, which with its longer parallel side 41 is even pivotally mounted on bearing bodies 42 about an axis YY parallel to the wheel axis 36 and has a bearing 44 for a guide piece 45 in the center on its shorter parallel side 43.
- the guide piece 45 can be pivoted about an axis XX by means of bearing pins 46 screwed into the bearing 44, said axis being directed parallel to the pivoting plane of the drawbar and at right angles to the drawbar 28.
- the guide piece 45 there is a guide opening 50, the extent of which parallel to the axis XX is significantly greater than the corresponding dimension of the rod 15 and the guide bodies 52, which are made of plastic and are concealed in FIG. 4, on their opposite boundary surfaces 51 directed parallel to the axis XX have, which are fastened by means of screws 53 to the side walls of the guide piece 45.
- the synchronous drive of the wheel pairs 18, 19, 38, 39 of both carriages 11, 12 are served by electric motors El, E2, which act on the differentials 30 and 40 and on the wheel axles 16, 17, 36, 37 via gears Gl, G2 which the wheel pairs 18, 19, 38, 39 are rotationally rigidly connected.
- the grinding modules 21, 22, 23, 47, 48, 49, the electric motors Gl, G2 and steering axle 24 can be operated from a driver's cab 29. 4 shows the steering kinematics of the wheel axle 17 schematically. As in part in the previous description, the two rail tracks are reduced to one rail track 26 for the sake of simplicity.
- the pull and push rod 15 ends at points E and F. Due to the length of the trapezoidal rods 28 ', 28 ", an optimal steering angle can be generated over the distance bj, through which an imaginary extension of the wheel axis 17 is the center point M of the circle of curvature Contains rail 26 with the radius R.
- the required steering angle ⁇ ⁇ which comes closest to the angle ⁇ j *, can be set over the lengths of the distances bj, ⁇ i stands for shorter and ⁇ 2 for longer trapezoidal rods.
- the axis 17 and possibly also the axis 16 or the wheel pairs 18, 19 attached to them can be mounted in an oscillating manner to compensate for unevenness in the rail and / or rail superelevation. A permanent frictional connection of the four wheels on the rail 26 can thereby be ensured.
- the chassis frame 14 is protected against great tension.
- the wheel pairs 38, 39 of the generator carriage 12 can be pivoted with their axes 36, 37, particularly when I2 is made approximately as large as lj.
- a suspension in particular an air or rubber suspension, can be provided so that bumps on the road can be better compensated for at transport speeds (10-30 km / h).
