Problems solved by technology

[0012] However, there is a problem with turnouts and crossings, in which each inner track branch (Schienenstrang) is broken in the region of the frog, so that the protruding rims of the outer rail wheels can be passed and adjusted in the turnout

Embodiment Construction

[0089] To describe the problem involved according to the invention, figure 1 The case of a rail vehicle frame passing through a switch is shown schematically, with three axles A extending in each case. The left side of the figure is a schematic top view, and the right side of the figure shows a front view of each axis A respectively corresponding to the axes A shown in the left top view. The extended shafts A are formed in two parts by two shaft elements AE which are relatively movable in the longitudinal direction of each shaft A. The stretch SM (Spreizmittel) engages the two shaft elements AE, and like the middle of the described shaft A shown especially in the figures, the two shaft elements AE press against each other in a way that the rim of the wheel R SK( ) is pressed against the rail edge (Fahrkanten) FK of the rail S, so that the axle A and the frame connected to it are aligned in a fixed orientation of the rail S without lateral play. refer to in figure 1 Axis A...

Abstract

By means of the invention there is provided a frame for rail vehicles comprising at least four rail wheels (1a, 1b) arranged thereon on at least two axles (2, 3) each having a variable track ) and a stretching device that stretches the rail wheels (1a, 1b) of each axle (2, 3) in the direction of variable track width; it also includes The modified and improved guides of the variable track, as guide plates not disclosed in the prior art and used here, also work reliably in the region of damaged rails and small bending radii. In the rail vehicle according to the invention, at least two axles (2, 3) variable in their respective wheelbases are connected by connecting means (8a, 8b) in such a way that such axles (2, 3) Has a minimum track that can also be used to preset other axes (2, 3).

Description

technical field [0001] The invention relates to a vehicle frame for a rail vehicle comprising at least four rail wheels on at least two axles each having a variable wheelbase arranged thereon and a stretching device for each The rail wheels on an axle extend in the direction of the enlarged track. Background technique [0002] A rail vehicle and its frame have a fixed wheelbase, which is used to transport people or goods, and for this purpose runs as a means of transport on a track on which rails are laid, the wheelbase being adjusted to the gauge of the railroad track. Typically, the track width of the vehicle, i.e. the distance of the rail wheels along the axle, is chosen such that there is some side clearance from the preset gauge on the track so that the rail vehicle can ride on the track "Swimming". This especially has to take account of balances and errors caused by slight changes in distance on the track relative to the rails, which may always be the case. [0003]...
