DE439212C - Automatic coupling for rail vehicles with coupling hooks that can be rotated horizontally in each half of the coupling and are under spring action - Google Patents

Description

The invention relates to such automatic couplings for rail vehicles, which can be rotated horizontally in each coupling half and are under spring action Coupling hooks work, which are locked in the coupling position by the latches raised by the hooks when coupling. The invention aims at the known automatic clutches of this type with simple construction and operation a reliable effect in that when coupling the coupling hook as a pawl or catch trained latches with their ratchet teeth behind special approaches of the coupling hook ^ so not only serve to lock the coupling hook, but also an auxiliary coupling at the same time represent.

The subject of the invention is on the

ao drawing illustrates in one embodiment, namely in

Fig. Ι through a horizontal and in
Fig. 2 through a vertical longitudinal section, while

s5 Fig. 3 a front end view of a Represents coupling half.

The housing 1 and 1 'of the two coupling halves are attached by an arm 11 to a bolt 9 on which arms 11 'are attached with counterweights 10. The bolt 9 is rotatable in pieces 16, which in turn are attached to the buffer beam Bolt 13 can be displaced between counter springs 14, 15 are arranged. The sliding bodies 16 are drilled out so far that the bolt 9 in the horizontal not only a shift, but also a pivoting movement can perform. As a result of this suspension, the coupling halves can automatically move adjust to their coupling position and also give way to the side when driving through curves.

In housings 1 and 1 'of the two coupling halves the two coupling hooks 2, 2 'are rotatably mounted on bolts 20, 20'. The facing surfaces of the Hook heads 22 and 22 'are bevelled in a wedge shape at 23 and 23'. The hook levers are up under the action of springs 5, 5 'attached to the housings, which strive to move the hook lever inwards into the effective Engage or clutch position to rotate, this inward movement by stops 17, 17 'is limited.

On the housing halves 1, 1 'are also at 21, 21 'lever-like or bolt-like latches 4, 4' rotatably mounted, which due to their own weight or under spring action have the endeavor, those in Fig. 2 in full lines to assume the horizontal bolt position shown, whereby it is disengaged Place the trolley on stops 24, 24 '. In the coupled position, each trap lies between the head of the hook lever 2 'or 2 of the other coupling half and the adjacent one Wall of the housing 1, 1 'so that they lock these levers in the coupled position and especially in curves, a disengagement

prevent the coupling hook from being pressed in any other way. In order to enable the lateral outward movement of the hook levers 2, 2 'during coupling, each hook head is provided on the side opposite the wedge surface 23, 23' with a catch 18, 18 'which, when pushed together, the latches by means of their wedge-shaped head ends 25, 2 Lift ζ ' into the upper ίο position shown in dashed lines in Fig. 2, so that the hook levers 2, 2' can move outwards laterally without hindrance.

Around the traps 4, 4 'when uncoupling also lift into the upper unlocking position shown in dashed lines in Fig. 2 to be able to, a shaft 19, 19 'is rotatable in each housing half 4, at the end a by weight 6 or 6 'loaded lever 26, 26' is attached, which endeavors to the associated Turn the shaft into the position shown in Fig. 2. There is one on every wave Lifting cam 3, 3 'attached, which upon rotation of the lever. 26 or 26 'by 180 ° in the indicated arrow direction the associated trap 4 or 4 'in the ineffective Position raises.

The shafts 19, 19 'also carry lifting cams 27, 27', the -mit. respective swing cams 28, 28 'of the hook lever 2 cooperate in such a way that after a rotation of the levers 26, 26' 270 ⁰ out of its normal position by the lifting cams 27, 28 and 27 ', 28' the associated hook lever 2, 2 'are rotated outwards into their uncoupled position, shown in dashed lines in Fig. 1. After rotation through 270 ⁰ to lie on the shafts 19, ig ^r to the levers 26, 26 'concurrently fixed arms 29, 29' on the lugs 18, ^ΐ8 Λ of the clutch lever and thereby prevent further rotation of the shafts 19, 19 ' beyond 270 ⁰ . The mode of operation is as follows: When the car is uncoupled, the hook levers 2, 2 ^r rest under the action of the springs 5, 5 'on the stops 17, ij ^r and the latches 4, 4' on the stops 24, 24 '. When the carriages are pushed together, the beveled ends of the locking levers 4, 4 'meet the upper wedge surfaces of the lugs 18, 18', and the sliding surfaces 23, 23 'run on one another. As a result, the latches 4, 4 'are raised into the dashed unlocking position shown in Fig. 2, right., And the hook ends 22, 22' of the levers 2, 2 'are raised to the outer position shown in broken lines in Fig. 1 against the springs 5 5 'rotated until the coupling halves are pushed so far against each other that the hooks 22, 22' snap under the action of the springs 5, 5 'in the position shown in the drawing and cause the coupling. The locking levers 4, 4 'also fall behind the lifting surfaces 18, 18' into the space between the hooks 22, 22 'and the adjacent housing walls, whereby the coupling levers 2, 2' are secured in the coupling position.

For the purpose of uncoupling the car, the shafts 19, 19 'are rotated through 270 ° into the position shown in Fig. 2, right, dash-dotted line. After completion of a 180 ° rotation of the locking lever 4, 4 'is raised by the lifting cams 3, 3' in the from Fig. 2, right, apparent unlocking position and in this case be at a further rotation of the shafts 19, 19 '90 ^0, so up to 270 °, the lifting cams 27, 28 or 27 ', 28' move the coupling levers 2, 2 'into the uncoupling position shown in dashed lines in Fig. ι against the springs 5, 5.' rotated, whereupon the carriages can be pushed apart. The arms 29, 29 'of the shafts 19, 19' remain on the lugs 18, 18 'until they are pushed apart. After they have been pushed apart, the weight levers 26, 26 'automatically _{fall back into their vertical position v} (Fig. 2) so that the parts resume their normal position and are ready for the next coupling process.
