Mobile machine for the treatment of a track, especially track compaction and / or straightening tamping machine

The invention relates to a mobile machine for treating a track, in particular track compaction and / or straightening tamping machine, with a by means of a on the chassis frame of the machine z-B. pivotable mounted carrier height-adjustable and on the bed top attachable bed compactor, its Compressor body is connected to a vibration exciter.

The aim of the invention is to make the chassis frame of such a machine against the vibration exciter of the compressor generated vibrations effectively and in a structurally simple manner without any special effort

009842/1103

Shield individual parts and thereby the performance of the compressor, which has so far been a considerable proportion was transferred to the carrier vehicle and thus lost went to increase.

It should also be avoided that the vibration exciter of the compressor is not operated at full power can work, so as not to prevent the components used to suspend the compressor fc endangering the machine and shortening its service life.

These objects of the invention are achieved according to the most essential feature of the invention in that between the compressor body equipped with the vibration exciter on the one hand and the one on the chassis frame the machine mounted carrier of this compressor body on the other hand at least one device for elastic absorption or damping of the vibrations is arranged

This device for damping the vibration

'gen can be made relatively small and robust, since it is only a relatively small one Area needs to extend. With a suitable design of the vibration damper it is also well ensured that the compressor body is able to adapt well to the respective course of the bed surface and is full of them The top of the bedding touches down, thus acting on the bedding at full capacity.

According to a particularly advantageous embodiment

life, ..

The device extends in the form of the subject matter of the invention for vibration damping with their individual parts over a surface that is preferably to the plane of the particular In the lateral bedding area, the underside of the compactor body to be placed on the ballast bed is parallel or runs at an acute angle. On top achieved this flat arrangement of the vibration damper you not only have an advantageous even distribution of the compression forces over a larger area of the bedding, but it is also guaranteed that the Compressor-Interseite nevertheless perfectly the course adjusts to the top of the bedding, with compensation of unevenness of the ballast bed top side within a relatively large area.

Various things are within the scope of the invention constructive solutions can be implemented. Particularly beneficial is to the device for vibration damping one even flat, made of elastic material, such as rubber od. Like. Existing vibration damper, z-B to enclose a plate made of elastic material, fm such plate-shaped vibration damper can be between two preferably also plate-shaped holders be stored, of which one with the carrier of the Compressor body, the other with the condenser body itself is connected.

Numerous other features of the invention who explained below with reference to the drawings for the sake of better understanding. These drawings show

in detail in FIG. 1 a track straightening, leveling and tamping machine in a longitudinal view, in FIG. 2 the suspension of a compressor body is shown axonometrically, FIG. 3 shows a partial front view Another embodiment of a compressor and its suspension on the machine and FIG. 4 relates to an embodiment variant of the vibration damper as a detail from Fig. 3 "

The chassis frame 1 according to FIG

^ the bogies 2 stationary track alignment leveling tamping machine

machine can be moved on rails 3 of the track. These rails 3 rest on cross sleepers 4-

The part of the chassis frame 1 of the machine that protrudes over the area of the track 3 »4 to be leveled carries a * t Track lifting device 5 Standard design. In this pre-

cantilevered part of the chassis frame 1 are also the height-adjustable track tamping tools 6 housed, which are arranged in two groups intended for tamping under two adjacent cross sleepers 4 of the track as a so-called twin tamping tool assembly.

Located between the two bogies 2

track straightening tools 7, which are laterally adjustable by means of hydraulic drives, not shown, to to move the track sideways into a target position

To compress the ballast bed 8 are

except the dipping into the ballast bed and the individual ties 4 under pot end tamping tools 6 also provided surface compressor, specifically designed surface compressor elongated in the track longitudinal direction 9 2 \ xr compaction of lying in front of the sleeper heads lateral Bettungsbereiches. these are located approximately at the rear of the track straightening tools in order to compact the ballast on the side of the track from which the track is locally moved to get into its target position, the device for placing this height-adjustable ballast compactor 9 on the ballast bed top in Fig. 1 generally denoted by Io,

To compress the so-called threshold compartments, d-h- the top of the bedding between two each other adjacent cross sleepers 4, so-called sleeper compartment compressors 11 are provided, which are supported by pivotable supports 13 and by means of piston-cylinder drives 12 are height adjustable,

Compressor for compacting the lateral bedding areas in front of the sleeper heads optionally also in the area of the track lifting tools 5 are ordered and are indicated by dashed lines in FIG and marked with 9 *.

The Fig.2 shows on a larger scale the on hanging one of the surface compactors shown in Fig.l 9, 9 'or 11 on a pivotally mounted

Carrier 14, of which only the outer end is visible. This The end of the carrier 14 is displaceable in a holding part 15 mounted with fasteners, ζ B-screws 15 'is attached to a plate-shaped holder 16. The holding part 15 is displaceable along the carrier 14, so that the distance of the compressor body from the joint of the carrier 14 can be chosen arbitrarily

Between the plate-shaped holders 16 and

^ 21, the latter formed by the web of a U-profile is the vibration damper, which according to the embodiment of Figure 2 from a plate includes elastic material. This plate 17 made of rubber od. The like. Extends with full cross-section over a essentially closed area and is in an Ab stood from the two holders 16 and 21 assigned to it arranged, of which one (161 with the carrier 14 of the compressor body 21-23, the other is connected to this compressor body itself. In detail there is the compressor body from the base plate 22, which is firmly connected to the holder 21, and from the upper part 23, with the base plate 22, a housing for the Eccentric shaft 24 forms.

As can be clearly seen from Fig. 2, are the places where the vibration damper made of elastic material, namely the plate 17, is connected to one (16) of the two holders 16, 21 or the carrier 14, separately and in the plane of the

The places where the plate-shaped vibration damper 17 with one or the other holder

16 and 21, respectively, are parallel to each other in a direction transverse to the longitudinal direction of the compressor body 21-23 extending rows arranged, the rows of such connection points at which the plate 17 with the one Holder 16 is connected, with rows at which it is connected to the other holder 21, in mutually alternating sequence and spaced from each other across the Surface of the plate 17 are arranged distributed.

'■. Each holder 16 or 21 is at the connection points by spacer strips 18 with convexly rounded contact surfaces each facing the plate 17 in the Maintained distance from the plate 17. To connect the Plate-shaped vibration damper 17, each with one of the two holders 16 or 21, are used for connecting bolts arranged in rows, e.g. screw bolts 2o, which the spacer strips IS of the holder and the plate of the vibration damper made of elastic material
