摘要： The invention relates to an energy supply system for a mobile resistance welding machine for flash-butt welding of track rails, comprising a combustion engine (1) coupled to a generator (2) as well as a charging device (5) for charging an energy store (7), wherein the energy store (7) is a buffer element of an intermediate circuit (13) to which a welding inverter (14) is connected. In this, the energy supply system comprises an island grid to which the generator (2) is connected and which is coupled to the intermediate circuit (13) by a controlled power converter (16).

摘要： A method for stabilizing a track having sleepers supported on a track ballast and rails secured to the sleepers, includes using a stabilizing unit which is connected to a machine frame that can be moved on the rails and has a vibration exciter and rollers that can roll on the rails. The vibration exciter generates in particular horizontal vibrations which run transversely to the track longitudinal direction. The course of a force exerted onto the track by the stabilizing unit is recorded over a vibration path during a vibration cycle by sensors. At least one parameter is derived from the course by an evaluation device and is used to evaluate the stabilizing procedure and/or the quality of the track ballast. A device for implementing the method is also provided.

摘要： For tamping a track, tamping tines are squeezed towards one another in pairs by a squeezing cylinder. A vibration is superimposed on a linear lift motion of a squeezing piston movable in the squeezing cylinder. The vibration is generated by a vibration piston which is arranged in the squeezing cylinder and which is movable independently of the squeezing piston.

摘要： A method for the correction of vertical position error of a track by a track tamping machine and a dynamic track stabilizer. Starting from a registered actual position, an over-lift value is prescribed for a treated track location with which the track is lifted into a preliminary over-lift track position and tamped. The track is subsequently lowered by dynamic stabilization into a resulting final track position. In this, a smoothed actual position course is formed from a course of the actual track position, wherein an over-lift value is prescribed for the treated track location in dependence of the course of the actual track position with regard to the smoothed actual position course. In this way, only short-wave track faults are treated with an over-lift value.

摘要： The invention relates to a tamping unit (1) for tamping sleepers (2) of a track (3), having a tool carrier (6) mounted on an assembly frame (12) for vertical adjustment by means of a drive (10), having pairs of two oppositely positioned tamping tools (5) which are squeezable towards one another about a respective pivot axis (4) as well as designed to be set in vibrations by a vibration drive (8). In this, it is provided that a vibration drive (11) is associated with the drive (10), the vibration drive setting the tamping tools in a vibration which is effective vertically.

摘要： A rail vehicle having a vehicle frame supported on on-track undercarriages and a hydraulic drive system powered by a motor. The drive system comprises a hydrodynamic drive associated with a first on-track undercarriage as well as a hydrostatic drive associated with a second on-track undercarriage. With the latter is associated a drive pump connected to a drive motor. The motor is designed for a higher power output than is necessary for the operation of the hydrodynamic drive. A pump distribution gear is switched between the motor and the hydrodynamic drive, via which the drive pump of the hydrostatic drive can be connected. This takes place in dependence on a friction value μ between the rail and wheel.

摘要： A transport vehicle includes a container for receiving bulk material which is disposed on a vehicle frame and is pivoted, together with a bottom conveyor belt and a third conveyor belt, relative to the vehicle frame about a pivot axis extending in a longitudinal direction of the vehicle in order to maintain a horizontal conveying plane, relative to a transverse direction of the vehicle, for the bottom conveyor belt and the third conveyor belt, independently of a transverse inclination of the track. Thus, a problem-free bulk material transport is possible even in the event of a transverse inclination of the track. A method of loading and unloading a transport vehicle which is mobile on a track is also provided.

摘要： A method for renewal of a track includes picking up a plurality of old track panels using a crane jib projecting over the track from a train end of a work train and depositing the old track panels on the work train, thus creating a renewal gap delimited by a gap beginning and a gap end. New ballast is introduced with the aid of the crane jib into the gap end of the renewal gap. Subsequently, a new track panel pre-deposited on the work train is placed by the crane jib on the graded ballast of the gap end. A work train for renewal of a track is also provided.

摘要： A tamping unit includes tamping tines and a squeezing drive for squeezing the tamping tines. A vibration exciter has an outer cylinder and an inner cylinder. The inner cylinder is disposed coaxially to a cylinder axis and is mounted for displacement in an axial direction along sliding or gliding surfaces in the outer cylinder. A ring-shaped recess is provided between the two sliding or gliding surfaces which are spaced from one another in the axial direction. A spacer ring, which subdivides the ring-shaped recess into two fluid channels, is connected selectively to the inner or outer cylinder. The fluid channels are spaced from one another relative to the axial direction. The two fluid channels can be hydraulically actuated alternatingly by feed lines for vibration excitation.

摘要： In a method for renewing a track (2) and cleaning a ballast bed (3), the old track (2) is lifted off the ballast bed in sections as a track panel (15), transported forward in a working direction (4) and deposited on track panel wagons (8). The exposed ballast bed (3), forming a renewal gap (17), is cleaned by a cleaning machine (11), spoil (32) accruing in the process is transported forward underneath the track panels (15) deposited on the track panel wagons (8), and stored in hopper cars (10). New rails (29), pre-deposited underneath new sleepers (27) positioned on sleeper wagons (14), are pulled forward into the renewal gap (17) by the cleaning machine (11) and deposited on the cleaned ballast bed (3). The new sleepers (27) are laid down on the cleaned ballast bed and connected to the new rails (29) lifted off the ballast bed (3).
