Description

AT 392 618 B

The invention relates to a buffer screed which can be swiveled out and removed on one of the end faces of a low-floor railway wagon and can be locked in the swiveled-in position by means of pin-hole connecting elements or the like with the side cheeks of the wagon

From EP-PS 0 019 098 a buffer screed is known which is mounted on both sides of the car by means of a vertical axis lying outside the car floor, both removable and optionally pivotable about one of the axes on the vehicle undercarriage. Due to the relatively high weight of the buffer screed and the elasticity of the side bolsters of the car, when opening the axle will initially tilt obliquely inwards, perpendicular when aligning with the side bolsters, and ultimately, when fully open, tilt obliquely outwards. When closing, the axis tilts in reverse order and the buffer screed must be lifted with force at the end of the closing process so that the axis is vertical and the buffer screed can be locked.

From FR-PS 2 026 167 and DD-PS 74 566 it is known to pivotally connect the buffer beams of a low-floor wagons to the wagon floor via swivel arms. However, these buffer beams are moved in the vertical direction in order to adapt the buffer elements of one wagon to the height of the buffer elements of the other wagon, so that, for. B. low-floor wagons with wagons of conventional type and a locomotive can be coupled.

The object of the invention is to provide a buffer board for a railway low-floor car, in which the side walls of the car are not burdened by the weight of the buffer board, so that the opening and closing process can be carried out with minimal effort, with a separation of the support elements from the Fasteners should take place.

This object is achieved according to the invention in a buffer screed of the type mentioned at the outset in that the buffer screed is pivotally connected to the car floor via at least one known pivot arm as a supporting element and the pin-bore connecting elements are preferably fixed on the buffer screed or on the side walls of the Wagens are arranged.

Further features and details of the invention are explained below with reference to the figures. FIG. 1 shows a first exemplary embodiment of a buffer board according to the invention in elevation, FIG. 2 shows the buffer board according to FIG. 1 in plan view, FIG. 3 shows a second exemplary embodiment of a buffer board according to FIG Invention in elevation, Fig. 4 the buffer board according to Fig. 3 in plan view, Fig. 5 a third embodiment of a buffer board according to the invention, Fig. 6 the buffer board according to Fig. 5 in plan view, Fig. 7 a fourth embodiment of a buffer board according to the Invention, and Fig. 8, the buffer board according to Fig. 7 in plan.

In the first embodiment according to FIGS. 1 and 2, (1) denotes the floor of the car and (2) the side walls of a low-floor car. The buffer beam (3) is mounted on one end of a swivel arm (4) so as to be pivotable about a vertical axis, which is also pivotably mounted on a support arm (5) at the other end about a vertical axis. The support arm (5) is angled at its lower end and sits in the horizontal direction as a cross-section z. B. rectangular profile part (6), which is arranged in a box (7) with the same inner profile in the horizontal direction, which is fixed transversely to the longitudinal direction of the car on the car floor (1). The displacement of the profile part (6) in the box (7) is preferably carried out by a spindle (8) with a nut (9) attached, which is attached to the end of the box (7). The spindle is rotatably mounted at the opposite end of the profile part (6) and can be rotated with a removable crank (10).

1 and 2 (as well as in the other figures), the buffer plank (3) is shown in the open state with dash-dotted lines. From both figures it can be seen that the buffer plank has two horizontally aligned pins (11) at the lateral ends, which are intended to be received in bores (12) in the side cheeks (2) and are used for uniform load transfer of the tensile and compressive forces. To open the buffer plank (3), turn it by turning the crank (10) to the left (in Fig. 1) until the locating bolts (11) have completely emerged from the holes (12), whereupon the buffer plank (3) is doggy is pivoted into the open division. To close the buffer plank (3), it is swiveled back and moved to the right by turning the crank (10) until the pins (11) have completely entered the bores (12).

By separating the support elements from the connecting elements, the weight of the buffer screed (3) is taken up in the open state by the stable carriage floor (1) and, on the other hand, the pins (11) and bores (12) provide a positive connection between the buffer screed ( 3) and the side cheeks (2)

By completely unscrewing the spindle (8) from the nut (9), the profile part (6) can be pulled out of the box (6) and the buffer board (3) can thus be removed from the carriage. Since the spindle (8) is arranged in the box (6), its thread is protected against icing. In the open state, the buffer screed (3) does not stand in the way of the motor vehicles as it can be pivoted through 270 ° from the closed state.

In the second exemplary embodiment according to FIGS. 3 and 4, a first pivot arm (4 ') is pivotally mounted at one end on the carriage floor (1) about a vertical axis. A second pivot arm (13) carries the buffer beam (3) and follows it at an angle continues below where it is pivotally mounted in the first swivel arm (4 ') about a vertical axis -2-

Claims (8)

AT 392 618 B Above this axis, a spindle (15) is pivotally mounted about a vertical axis, which is seated in a nut (14) which is rotatable on the buffer beam (3) and can be pivoted about a vertical axis. The spindle (15) is by a removable crank (16) can be turned. The pins (11) and the bores (12), as in the first embodiment according to FIGS. 1 and 2, are aligned horizontally. By turning the crank (16), the buffer plank (3) can be adjusted transversely to the longitudinal axis of the carriage, around the pins (11) with the holes (12) to lock or unlock. In the third exemplary embodiment according to FIGS. 5 and 6, a preferably cranked swivel arm (4 ') is mounted on the end of the carriage (1) so that it can swivel about a vertical axis. The other end of the swivel arm (4 ") is connected to the buffer screed (3) so that it can pivot about a vertical axis via a mechanical or hydraulic lifting device (17). By actuating the lifting device (17), the buffer screed (3) can be raised and lowered in order to lock or unlock the vertically aligned pins (11 ') with the vertically aligned bores (12'). In the fourth embodiment according to FIGS. 7 and 8, like the second embodiment according to FIGS. 3 and 4, two swivel arms (4 ') and (13) and, like in the third embodiment according to FIGS. 5 and 6, a lifting device (17) below the buffer screed ( 3) is provided, the pin-bore connecting elements (11 ') and (12') being aligned perpendicularly as in the third exemplary embodiment. The removal of the buffer screed (3) from the car takes place in the three examples according to FIGS. 3 to 8 in that either the bearing of the swivel arm (4 ’), (4 ″) attached to the car floor (1) is removed, e.g. B. is unscrewed, or that the journal is lifted out of this bearing.
