Problems solved by technology

Here too, when preloaded into the stop on the vehicle side, there is a gap between the hinge shaft and the housing, which causes shocks and drags in the train during travel
The stabilizing hinge is weakened in terms of its stabilizing effect due to the spherical bearing on the hinge axis

Embodiment Construction

[0029] exist figure 1 In , the traction buffer device of flange structure is shown in a half-section top view with a connecting arm for the intermediate buffer coupling of rail vehicles. The traction buffer device 100 is screwed to the undercarriage 1 of the rail vehicle via a screw connection part 24 . The connecting arm with the connecting head 2 is articulated on the hinge shaft 4 via the hinge gap spring damper 7 .

[0030] exist figure 2 , the traction buffer is shown in side sectional view. The hinge 3 is supported by the end surface against the pressing plate 8, and the pressing plate transmits the pressing force to the reversible energy consumption system composed of the shock absorber 13 and the unloading spring 14 when the pressing plate is pressed, wherein, through the inner cover plate 15 towards The inner housing 16 provides support. The inner housing 16 is pressed against the deformation element 23 via the stop 17 , the deformation element is then supported ...

Abstract

The invention relates to a pulling and pushing device (100) which comprises a coupling arm (2) for a central buffer coupling of rail vehicles, is flangedly-mounted on the chassis (1) of the rail vehicle and elastically maintains the coupling arm (2) with the coupling head thereof by means of a hinge (3), preferably a stabilisation hinge, hingeable on a hinge pin (4). The inventive device withstands pressure forces in a pressure direction (56) when the hinge spring clearance (7) is exceeded without play by means of a pressure plate (8) and a pressure-sided energy absorption system (9) which isplaced downstream and is prestressed on the chassis (1) by means of an external housing (10). The aim of said invention is to design a pulling and pushing flanged-mountable device which comprises a high-energy absorption system providing an optimal protection in the event of a crash with a non-linear characteristic curve of a spring system for damping longitudinal vibrations during a drive and mounting in a free-play manner the coupling arm used for reducing shocks and slack actions during travelling. For this purpose, the pressure-sided multilayer energy absorption system (9) and a pull-sited energy absorption system (11) are serially connected inside the housing (10).

Description

technical field [0001] The invention relates to a traction buffer device with a connecting arm, which is used for the intermediate buffer coupling of a rail vehicle. The traction buffer device is fixed on the chassis of the rail vehicle with a flange, and is hinged on a hinge shaft The hinge, especially the stable hinge, elastically supports the connecting arm with the connecting head, and, in the pressing direction, makes the pressing force pass through a pressing plate and a connection without play after exceeding the hinge gap spring damper The prestressed, pressure-side energy dissipation system is supported on the chassis via an outer housing and, in the traction direction, the traction force is passed through the traction stop without play via the hinge shaft and a traction-side energy dissipation system and the outer shell are supported on the chassis. Background technique [0002] Such a device is known, for example, from EP 1 225 114 B1. [0003] According to DE 1...
