Definitions

  • the present invention relates to a central buffer coupling for track-guided vehicles according to the preamble of claim 1.
  • the invention particularly relates to a central buffer coupling for rail-guided vehicles, preferably an automatic central buffer coupling for rail vehicles, wherein the central buffer coupling has a coupling head for mechanical coupling with a complementary mating coupling head.
  • the coupling head has a flat, vertically extending end face. On a first end face half a front end of the projecting centering projection is provided. On the second end face half, a funnel extending into the interior of the coupling head is provided symmetrically with respect to the centering projection.
  • the coupling head has a decentralized, preferably below the coupling head, the front surface superior gripper for axial pre-centering when coupling a same counter-coupling head.
  • FIG. 1 Such a central buffer coupling is already known in principle from rail vehicle technology.
  • the coupling head 101 has an end face 102, wherein on a first end face half - in the embodiment shown in Fig. 1a on the right end face half - a front surface 102 projecting forward centering projection 103 and on the second end face half - in the in Fig. 1a embodiment shown on the left end face half - symmetrical to the centering projection 103, a funnel 104 is provided, which extends into the interior of the coupling head 101.
  • the gripper 105 is arranged with respect to the coupling head 101 such that it covers an area below the funnel 104 in front of the end face 102 of the coupling head 101. This area covered by the gripper 105 defines the gripping area of the coupling head 101.
  • the gripper 105 serves for the axial precentering of the coupling head 101 when coupling a mating coupling head of the same design to the coupling head 101 (in FIG Fig. 1 not shown).
  • the in Fig. 1 illustrated coupling head 101 of the known from the prior art center buffer coupling 100 as a centering projection 103 a semi-spherical ball stud, which engages when coupling a coupler head 101 of the same counter-coupling head formed as a corresponding recess funnel of the counter-coupling head.
  • This is facilitated by the semi-spherical configuration of the front end portion of the centering projection 103.
  • the semi-spherical end region of the centering projection 103 merges in the direction of the end face 102 into a quasi-cylindrical region.
  • the lateral surface of the cylindrical portion is used in the coupling process as a guide surface which cooperates with the hopper of the mating coupling head and aligns the mating coupling head substantially axially to the coupling head 101.
  • the gripping area defined by the gripper 105 of the coupling head 101 thus indicates which offset, deviating from the exact axial alignment, of two central buffer couplings to be coupled for proper coupling must not be exceeded.
  • FIGS. 2a and 2b such a scenario is shown.
  • Fig. 2a two coupling heads 101, 101 'of a central buffer coupling, for example of the "Fischer" type, in which although a coarse centering of the coupling heads 101, 101' has already taken place with the aid of the respective grippers 105, 105 ', so that the respective centering projections of the two together coupling coupling heads 101, 101 'are at least partially retracted into the respective funnels.
  • FIGS. 2a and 2b illustrated coupling heads jammed each other, since the with the grippers 105, 105 'caused pre-centering could not align the end faces 102, 102' of the coupling heads 101, 101 'exactly parallel to each other.
  • FIGS. 2a and 2b jammed occurs, about 3 mm before the end faces 102, 102 'of the coupling heads 101, 101' could touch.
  • the present invention seeks to further develop a central buffer coupling of the type mentioned in that in a simple to implement but effective way jamming of two coupling heads to be joined together during the coupling process can be prevented.
  • this object is achieved according to the invention, on the one hand that in a central buffer coupling of the type mentioned the gripper is attached to one half of the coupling head to the coupling head, and on the other hand that the coupling head further comprises a guide pin on the other half of the coupling head, wherein the guide pin is formed is to form a guide when coupling the counter-coupling head with the gripper of the counter-coupling head to provide an axial fine adjustment of the coupling head.
  • the coupling heads to be coupled are aligned exactly axially to each other in the coupling process, so that jamming or tilting of the centering of the coupling head in the hopper of the mating coupling head is practically no longer possible.
  • the guide pin of the coupling head allows a further approach of the coupling heads to be coupled only when the counter-coupling head with respect is aligned exactly axially on the coupling head.
  • the guide pin is arranged on the coupling head such that it falls into the gripping region of the gripper fastened to the counter-coupling head when coupling the counter-coupling head. Since - as already stated - the interaction between the guide pin of the coupling head on the one hand and the gripper of the counter-coupling head on the other hand serves for fine adjustment of the axial alignment of the coupling heads to be coupled, it is preferred if the guide pin only then falls into the gripping region of the counter-coupling head attached gripper, when the two faces of the coupling heads to be coupled (coupling head and counter-coupling head) have already approached to a few millimeters.
  • the axial alignment between the coupling heads to be coupled is the more accurate, the later falls during the coupling process, the guide pin of the coupling head in the gripping region of the counter-coupling head.
  • the guide pin of the coupling head should only fall into the gripping region of the counter-coupling head gripper when between the end faces of the coupling head and the counter-coupling head is only a few millimeters distance, in this way jamming of the centering in the corresponding funnel effectively to be able to prevent.
  • the gripper of the coupling head is attached to the coupling head and designed so that it covers an area below the funnel in front of the end face of the coupling head.
  • the gripper of the coupling head is attached to the coupling head and designed so that it covers an area below the funnel in front of the end face of the coupling head.
  • the solution according to the invention is further distinguished by the fact that conventional coupling heads of the " Fischer" type can be retrofitted with an axial fine adjustment in an easy-to-implement and, in particular, cost-effective manner, without the need for complicated conversion measures on the coupling head. It is only necessary to attach the guide pin to the coupling head so that it falls into the gripping area of the gripper of the mating coupling head, as soon as the distance between the end faces of the coupling heads to be coupled is only a few millimeters. Accordingly, it is advantageous if the guide pin is connected, for example via a screw detachably connected to the coupling head.
  • Fig. 3 shows in a perspective oblique view from below the coupling head 1 of a central buffer coupling according to an embodiment of the present invention during the coupling process with a coupler head 1 identically designed counter-coupling head 1 ', wherein the counter-coupling head 1' with respect to Coupling head 1 is not exactly aligned axially.
  • Fig. 3 a state shown in which the two to be coupled coupling heads 1, 1 'are already roughly aligned with each other.
  • the gripper 5 is attached to an edge region of the coupling head 1.
  • the gripper 5 has a typical for central buffer couplings of the "Fischer" configuration and covers before the end face 2 of the coupling head 1 a portion below a provided on the left end face half of the end face 2 hopper 4 from.
  • the counter-coupling head 1 ' is identical to the coupling head 1 executed. Accordingly, in the accompanying drawings, the components of the counter-coupling head 1 'are provided with corresponding reference numerals. On an explicit description of the structure and operation of the mating coupling head 1 'is omitted here. Rather, reference is made to the corresponding statements to the coupling head 1.
  • a guide pin 7 is provided which on the gripper 5 opposite side - at the in Fig. 3 illustrated embodiment on the right side - the coupling head 1 is fixed.
  • the attachment of the guide pin 7 on the coupling head 1 can be done for example via a screw 8. This is particularly advantageous if a conventional coupling head of a "Fischer" type central buffer coupling is to be retrofitted with a fine adjustment, as proposed herein.
  • the guide pin 7 is formed and attached to the coupling head 1, that this in the gripping region of belonging to the mating coupling head 1 'gripper 5' falls as soon as the respective end faces 2, 2 'of the coupling head 1 and the mating coupling head 1' have approached to a few millimeters.
  • the guide pin 7 falls into the gripping area of the gripper 5 'belonging to the mating coupling head 1', the axial fine alignment takes place between the coupling heads 1 and 1 'to be coupled, as a result effectively preventing any jamming or tilting of the respective centering projection entering the associated hopper can be.
  • the gripper 5 used in the embodiment according to the invention and the structural and functional point of view correspond to the gripper 105 which is used in the gripper 105 in FIG Fig. 1 shown and known from the prior art middle buffer coupling type "Fischer" is used.
  • the gripper 5 has a guide surface 8, with which forms the guide for fine adjustment of the coupling head 1 when coupling the counter-coupling head 1 'of the guide pin of the identical to the coupling head mating coupling head.
  • the guide surface 9 extends downwards against a horizontal and inclined against the plane of the end face 2, in order to guarantee a large gripping area in side and height, which also allows coupling in curves, or at crests.
  • Fig. 4 is a view of the coupling head 1 of a central buffer coupling according to an embodiment of the invention, in a plan view in the direction of the coupling plane.
  • Fig. 4 a state shown in which the Coupling head 1 to the coupling head 1 'couples a counter-coupling, although the coupling head 1 and the counter-coupling 1' are not exactly aligned axially to each other.
  • Fig. 5 shows a state after the counter-coupling head 1 'has been axially aligned relative to the coupling head 1 by means of the guide pin 7.
  • the two coupling heads (coupling head 1 and mating coupling head 1 ') are aligned exactly axially to one another, so that the respective centering projection can completely retract into the appropriate funnel without the risk of jamming or jamming.
