Definitions
- the invention relates to a pulling device for rail vehicles, essentially consisting of a support plate that can be connected on the vehicle side, a spring unit and a pulling element for connecting the spring unit to a coupling arm of a pulling hook or an automatic pulling coupling.
- the pulling member is designed on one side as a fork-shaped pulling rod.
- This pull rod which engages via a pull plate and a central nut at the rear end of the spring unit, penetrates a hole arranged approximately centrally in the support plate fastened on the vehicle side.
- a dome arm of a pull hook is attached by means of a bolt.
- DE-PS 34 23 808 also includes a pulling device for rail vehicles in the prior art, in which the pulling element and the pulling hook are a one-piece component form, which surrounds the support plate and the spring unit frame-like. This component is horizontally pivotably mounted in a receptacle arranged behind the spring unit and guided on the support plate in the pivoting direction.
- the traction device with the one-piece component described above is complex in terms of manufacture.
- the pulling device must be removed from the vehicle and disassembled to replace this component (especially if the pulling hook is worn).
- the invention has for its object to design a traction device of the generic type using simple and robust means so that an uncomplicated, inexpensive manufacture and largely wear-free use can be achieved over a long period of time; in this case, it may be possible to carry out a necessary replacement of a pull hook or a comparable component of an automatic pull coupling with the pull device connected unchanged on the vehicle.
- the tension member is formed from two spaced-apart tabs, which are united by a rear connecting bolt cooperating with the spring unit and by a front connecting bolt which also receives the coupling arm, both tabs being mounted in the support plate so as to be longitudinally displaceable and is led.
- FIG. 1 and 2 show a pulling device according to the invention in a longitudinal view and in the associated top view.
- 3 and 5a each contain different design options for the area of the traction device on the left in the drawing plane of FIG. 1.
- 5b and 5c are supplementary views to FIG. 5a, in the direction of the arrow X or the arrow Y there.
- Fig. 6a, 6b and Figures 7 to 9a relate to alternative embodiments of the right in the drawing plane of Figure 1 area of the traction device.
- Fig. 9b is the top view of Fig. 9a.
- the pulling device has a support plate 8 which can be connected in a conventional manner (not shown here) to its laterally spaced flanges 8a on supports of the vehicle undercarriage and is supported in the pulling direction by corresponding lateral stops of the vehicle. Furthermore, the pulling device contains a spring unit 7, which in the present exemplary embodiment has a spring housing which is formed from two telescopically interacting housing pots 7a and 7b, and a friction spring which is shielded in this spring housing.
- the pulling device also includes a pulling element 1, which serves to connect the spring unit 7 to a coupling arm 6 of a pulling hook or an automatic pulling coupling. 1 are provided with a view to guiding the coupling arm 6 spacers 6a made of plastic, which can however be omitted for the coupling arm 6 in the presence of a vehicle-side guide - generally on the head carrier.
- the tension member 1 is formed from two brackets 2 and 3 arranged at a vertical distance from one another. Both the upper bracket 2 and the lower bracket 3 are mounted and guided in a longitudinally displaceable manner in the correspondingly recessed support plate 8. Both tabs 2 and 3 have pressure stops 2b and 3b, which cooperate with the front surface of the support plate 8 and thus determine the biasing force of the spring unit 7.
- tension member 1 Further components of the tension member 1 are a rear connecting bolt 4, which interacts with the spring unit 7, and a front connecting bolt 5. These bolts 4 and 5, which are only shown in their respective line of action in FIG. 1, are in respective bores 2a and 3a of the upper plate 2 and the lower tab 3 used and held to unite the tabs 2 and 3 relative to them.
- the front connecting bolt 5 also serves to receive the coupling arm 6. From the overall structure, the tension member 1 is similar to the principle of one
- the connecting bolt 5 is inserted into the bores 3a and 2a from below until it abuts a stop plate 10 which is fastened to the upper bracket 2 by means of a weld seam 10a (alternatively by screws). 3 secures a connected to the lower tab 3 by screws 11a Holding plate 11 the connecting bolt 5 in the assembled position. According to FIG. 4, this takes place on the one hand via a securing ring 9 which engages in a bolt groove located outside the lower tab 3, and on the other hand via a fastening screw 13 which is attached to the
- Stop plate 10 of the upper tab 2 is attached and cooperates with the connecting bolt 5.
- the two tabs 2 and 3 can be fixed in position with respect to one another with the aid of webs 14 (see FIG. 3).
- An auxiliary thread 5a facilitates the removal of the
- Holding plate 11 (Fig. 3) or the locking ring 9 (Fig. 4) possible removal of the connecting bolt 5 downwards.
- the holder of the connecting bolt 5 shown in FIGS. 5a to 5c relative to the brackets 2 and 3 also contains the aforementioned fixing function, but without webs 14.
- the connecting bolt 5 and the upper bracket 2 are designed as follows in the manner of a bayonet connection :
- the connecting bolt 5 has groove-shaped sections 5b, which extend between two lateral flats 5c.
- the upper tab 2 is provided with two welded-on retaining plates 2d, through which the bore 2a is locally reduced.
- the transverse spacing of the holding plates 2d is slightly larger than the width of the connecting bolt 5 remaining between the flats 5c, so that it can pass through the holding plates 2d in a position rotated by 90 ° with respect to FIG. 5b. In the position according to FIG.
- a fork-shaped holding plate 11 is fastened to the lower tab 3 by screws 11a. This holding plate 11 engages through its fork arms 11b in lateral incisions 5d of the connecting bolt 5, which is thereby fixed in the vertical direction and in the U direction. An expansion of the connecting bolt 5 is after removing the fork-shaped holding plate 11 and turning the connecting bolt 5 by 90 ° easily possible.
- the rear connecting pin 4 can also be held in relation to the two tabs 2 and 3 by the components described in connection with the front connecting pin 5 and which can be combined with one another - securing ring 9, screw-on plate 10, holding plate 11 - as shown in FIGS. 6a to 9b can be seen.
- the configuration as a bayonet connection explained with reference to FIGS. 5a to 5c and the use of the fork-shaped holding plate 11 can also be carried out with respect to the connecting bolt 4.
- the connecting bolt 4 each has a cylindrical cross section. In the sense of good force introduction, this bolt interacts with the spring unit 7 with the interposition of an adapter 12 which has a trough-shaped curve which is adapted to the bolt diameter.
- two web-like pressure pieces 12a serve as adapters 12, which are each welded to the bottom of the outer housing pot 7a of the spring unit 7 and encompass the connecting bolt 4 in a semicircular shape.
- the pressure pieces 12a and the bottom of the housing pot 7a can also be in one piece, production by flame cutting and subsequent bending of the pressure pieces 12a with respect to the housing base being offered by 90 °.
- the connecting bolt 4 shown in FIG. 8 has a semicircular cross section, the flat surface 4a of which rests against the bottom of the outer housing pot 7a of the spring unit 7.
- the connecting bolt 4 is square, a rectangular cross section also being possible.
- the square connecting pin 4 also transmits the tensile forces that occur directly via its flat surface 4a to the outer housing pot 7a of the spring unit 7.
- retaining rings 9 can also be used. engage the grooves contained only in the corner area of the connecting bolt 4 (see Fig. 9b).
