Definitions

  • the invention relates to a coupling in particular for a rail vehicle with a coupling head according to the preamble of claim 1.
  • the respective coupling head is formed from a two-part or multi-part housing. It is provided with a coupling member and the other coupling head with a corresponding recess. This coupling member is intended to engage in the recess of the other coupling head when coupling. It is assigned to this a securing member for securing the coupled coupling member.
  • a locking mechanism is designed as a lever arrangement in the housing, in which a locking element is provided which has a bolt rotatable about a vertical axis, which can be rotated between an initial and an active position and is in operative connection with the unlocking lever via an intermediate lever.
  • This unlocking lever is intended for direct or indirect securing of the securing member in the locked position and for unlocking the locking mechanism, the intermediate lever and the unlocking lever being pivotably mounted. A reduction in the locking force is also provided, which enables manual unlocking.
  • Another coupling head according to the Swiss patent application No. 00805/19 is provided with a housing which has on the front side an abutment surface for a flat support with an abutment surface of a coupling head to be coupled and on the rear side a connection flange for attachment with a tie rod or the like.
  • a coupling and locking mechanism is integrated in the housing.
  • the housing is essentially made as a one-piece pot shape, in which the abutment surface is formed on the front wall or this connection flange is formed on the rear wall. Due to its design with this compact housing, the coupling head is optimally designed to absorb the very high tensile and compressive forces that occur during the coupling process and with the coupled rail vehicles in operation, especially when accelerating or braking.
  • the invention is based on the object of improving a coupling with a coupling head of the type mentioned at the outset in such a way that its integrated locking and unlocking mechanism is designed to be simpler while functioning reliably.
  • This unlocking member assigned to the locking or unlocking mechanism can be connected to the main air line and / or the main container air line, and the compressed air causes this locking or unlocking mechanism to be unlocked and thus the coupling to be uncoupled.
  • This unlocking element which is operatively connected to the bolt of the coupling and locking mechanism in the housing, enables coupling to be effected automatically or the coupling head to be decoupled and, consequently, two coupled rail vehicles to be released by a control means at the push of a button if necessary.
  • this unlocking member can be moved into a first position during coupling by means of the bolt pivotable from the other coupling head, while it can be adjusted to a second position by an actuatable drive movement, in which it unlocks and consequently uncouples the bolt.
  • FIGS. 1 to 3 show a coupling head 10, which is particularly useful in rail vehicles, such as preferably in freight cars, but also in Passenger cars and locomotives is used, but in principle it could also be used to couple other cars.
  • This coupling head 10 is provided with a housing 20 which, on the front side, has an abutment surface 12 for a flat support with an abutment surface of another coupling head to be coupled for the coupling of two rail vehicles or the like.
  • a connection flange 11 At the rear of the housing 20 there is a connection flange 11, by means of which it is fastened with a pull rod or the like of a coupling device which can be fastened in an articulated manner to a vehicle body.
  • a guide vane 15 is preferably arranged for centering the coupling heads 10 to be connected at an angle to the coupling direction A.
  • it corresponds to a guide vane of the coupling head to be coupled, which is designed identically to the coupling head 10 shown, but is attached to the coupling device of the vehicle to be coupled, pivoted horizontally through 180 °.
  • a locking and unlocking mechanism 40 is integrated, which comprises a lever system with interacting pivotable levers, which is explained in more detail below.
  • This pivotable bolt 45 is mounted in the interior of the housing 20 so as to be pivotable about a vertical axis 45A to the bottom wall 23 from an initial to an operative position and vice versa.
  • This bolt 45 has a wing part 46 protruding towards the abutment surface 12 with a contact surface 46 'and opposite a wing part 46 ′′.
  • the outer wing part 46 comes with a front surface (29') of the Housing part (29) of the other coupling head in contact and a rotation of the bolt 45 is caused.
  • this bolt 45 is operatively connected to a roller 41 of a roller lever 41 pivotable about an axis 41A, in which this roller 41 'is in contact with a guide track 47', 47 "of a protruding nose 47 of the bolt 45 by a spring force of a spring
  • the bolt 45 is pivoted clockwise about the axis 45A by the other coupling head and the roller 41 'slides along its guide path 47', 47 "of the nose 47.
  • the bolt 45 with its recess 48 is on a corresponding support surface of the other coupling head , it is in the coupled position and this roller 41 'rests on the guide track 47 ".
  • roller lever 41 interacts with a cam lever, not shown in detail, of the locking and unlocking mechanism 40 in a manner known per se, in which this cam lever can be pivoted about an axis into a position engaging behind the roller lever 41 and thus locking it so that the latter and likewise the latch 45 cannot unintentionally release from the coupling position.
  • an unlocking member 50 which is arranged in the housing 20 and can be actuated and is articulated to the locking and unlocking mechanism 40, is arranged on the rear side of the bottom wall 23 of the housing 20 and runs parallel to the latter and as a pneumatic piston / cylinder unit with a piston rod 51 which is articulated on a steering lever 52 pivotable about an axis of rotation 53.
  • this pneumatic piston / cylinder unit is designed with a pressure chamber 57 which can be controlled by a valve 60 as control means, a branch line 59 leading from the main air line 61 to the valve 60 and, in its open state, into this chamber 57 .
  • this unlocking member 50 in the coupling head 10 can be connected to the main air line 61, and the compressed air therein enables this locking or unlocking mechanism 40 to be unlocked and thus the coupling to be uncoupled.
  • the unlocking member 50 is moved during coupling by the bolt 45 pivotable from the other coupling head and the lever linkage 43, 44 in a first position in which this pressure chamber 57 approximately is closed, but when uncoupling the valve 60 is opened and thus the compressed air is passed from the main air line 61 into the pressure chamber 57 of the unlocking device 50, so that by moving the piston rod 51 into a second position, the cam lever is unlocked from the roller lever 41 and consequently the bolt 45 is pivoted into the uncoupled position.
  • the unlocking member 50 can be adjusted in this one direction by a control means by means of a manually or externally operated switch or the like.
  • the cylinder 50 ' is articulated on an axis 56 and opposite the piston rod 51 is rotatably connected to the piston via the steering lever 52 with the axis of rotation 53, the latter protruding vertically through the housing 20 and on the front of the housing 20 it is by a cam 54 and a transmission rod 55 articulated on this with an axis 42, which in turn cooperates with the cam lever.
  • the outside of the cam 54 is curved in such a way that a rocker arm 69 of a valve 59, which presses against it, is pivoted by a certain angle in order to actuate the valve 59.
  • the closing valve 30 or a valve for coupling or uncoupling an electrical coupling as part of the coupling can be actuated.
  • This main air line 61 in the coupling head 10 contains a closing valve 30 and a connecting means 65 in a manner known per se.
  • This connecting means 65 comprises a plunger 66 adjustable in its axis, a sleeve 67 guiding this and a compression spring 68.
  • This plunger 66 can project, valve-controlled, to the abutment surface 12 of the coupling head 10 and into an opening of a main air line a coupled coupling head, not shown, can be inserted so that a tight connection of the main air line 61 between the heads is made possible.
  • the closing valve 30 in the main air line 61 comprises a stationary guide sleeve 31, a closing piston 35 guided by this with a cavity 36 and a compression spring 32 arranged therein.
  • the closing piston 35 In the closed state, the closing piston 35 is with its upper end 35 'on an annular surface of 90 ° angled main air line 61 sealingly.
  • This closing piston 35 is arranged displaceably at the bottom in a cylinder chamber 34 which is connected to a valve via a branch line not shown in detail.
  • the plunger 41 is also pushed forward when this valve is opened.
  • the housing 20 is advantageously produced as a one-piece pot shape, in which the abutment surface 12 is formed on the front wall 21 and at least one guide vane 15 is formed on the side of this and this connecting flange 11 is formed on the rear wall 22.
  • This essentially one-piece pot-shaped housing 20 is cast and it is preferably made of steel or nodular cast iron with a predetermined minimum value of its tensile or compressive strength. In principle, however, the housing could be welded together from different parts in the sense of a one-piece pot shape.
  • the underside is an opening formed by its encasing wall provided, in which this unlocking member 50 and this pivotable steering lever 52 are included.
  • At least one continuous angled line wall 25 with openings 27, 28 is formed along its lower bottom wall 23, which is guided from the front wall 21 with the abutment surface 12 to the rear wall 22 or at most to the side wall 24 of the housing 20 and which serves to lead through a main air line with an existing operating pressure for the brakes and preferably a main container line for the compressed air supply to the rail vehicles.
  • This angled line wall 25 serves as a reinforcement of the housing 20.
  • the planes formed by the abutment surface 12 at the front wall 21 and the planes formed by the rear wall 22 with the connecting flange 11 extend in a V-shape and the side walls 24, 26 connecting them preferably extend inward from the rear wall against the front wall in order to thereby to achieve maximum strength of the housing.
  • the housing 20 which essentially consists of a one-piece pot shape, is assigned an extending housing part 29 to the pot to form a recess 14 on the side of the abutment surface 12, the height of which is slightly smaller than that of the housing 20.
  • This extending housing part 29 protrudes from the front wall 21 in the same plane and it is connected to the side wall 24 of the housing.

  • the invention is sufficiently demonstrated with the above exemplary embodiment and the variants mentioned. However, it could also be implemented through further alternatives.
  • the unlocking member 50 could be arranged directly next to the cam lever and instead of a pneumatic piston / cylinder unit, a rotary motor or some other drive could also be used.
  • the piston / cylinder unit could also be fed from the main container air line HBL.
  • the housing could also consist of several parts and, like the lever system with the lever linkage and the various levers, it could be configured differently.
