Abstract

A machine (1) for stabilization of a track (2) has a machine frame (5), mobile on the track by means of on-track undercarriages, on which a stabilizing unit (4) is arranged which has vertical adjustment drives (6) as well as a vibration exciter (7). The stabilizing unit is designed to be displaceable relative to the machine frame (5) in a longitudinal direction (23) of the machine by means of a longitudinal displacement drive (24).

First claim

The invention claimed is:

1. A machine for stabilization of a track comprising:
a machine frame mobile on the track by means of
a plurality of on-track undercarriages coupled to the machine frame;
a stabilizing unit comprising a plurality of vertical adjustment drives and a vibration exciter;
wherein the stabilizing unit is designed to be displaceable relative to the machine frame in a longitudinal direction of the machine by means of a longitudinal displacement;
wherein, between the machine frame and the stabilizing unit, a thrust drive is provided which is articulatedly connected at a first end to a thrust lever and by a second end to the stabilizing unit, wherein the thrust lever has a lower end—with regard to the vertical—which is articulatedly connected to the stabilizing unit while a thrust roller provided for application to the machine frame is arranged at an upper end.

2. A machine for stabilization of a track comprising:
a machine frame mobile on the track by means of
a plurality of on-track undercarriages coupled to the machine frame; and
a stabilizing unit comprising a plurality of vertical adjustment drives and a vibration exciter;
wherein the stabilizing unit is designed to be displaceable relative to the machine frame in a longitudinal direction of the machine by means of a longitudinal displacement
wherein a compensating lever is provided which is connected by a first linkage to the machine frame and by a second linkage to the stabilizing unit, and wherein the longitudinal displacement drive is connected between the two linkages to the compensating lever.

3. The machine according to claim 1 , wherein a speedometer connected to the stabilizing unit or the machine frame is provided which is designed to roll on a rail of the track.

4. The machine according to claim 1 , wherein flanged rollers, designed to roll on the track, of the stabilizing unit are connected in each case to a separate, independently actuatable hydraulic drive.

5. The machine according to claim 2 , wherein a speedometer connected to the stabilizing unit or the machine frame is provided which is designed to roll on a rail of the track.

6. The machine according to claim 2 , wherein flanged rollers, designed to roll on the track, of the stabilizing unit are connected in each case to a separate, independently actuatable hydraulic drive.
