Definitions

  • the invention relates to a push device for railway cars.
  • a buffer for railroad cars which has a buffer tappet with a buffer plate has on the front.
  • a spring is provided in the buffer tappet and the buffer tappet itself is slidably inserted in a buffer sleeve.
  • the buffer sleeve is opposite one end flange lying on the buffer plate.
  • the end flange has holes in it Screws can be used to attach the buffer to the buffer carrier.
  • Out A Polish patent application PL 114281 discloses a buffer in which the Buffer sleeve has an attachment lying opposite the buffer plate, which consists of two Parts exist and is welded to the buffer sleeve.
  • the buffer tappet points to his free end a projection, such that the two parts of the attachment and the Projection a limiting means for the stroke movement of the buffer tappet relative to the Form the buffer sleeve.
  • a slidingly inserted inside the buffer tappet the buffer plate opposite shock sleeve and a shock plate provided, the Shock sleeve has a projection on its front side, which on the abutment surface of the Buffer plunger abuts, as well as the shock sleeve on its back on the in the buffer axis lying push plate.
  • a locking seat must be formed in the shock sleeve, such that, with a buffer plunger fully inserted into the buffer sleeve, the Locking seat is located opposite a locking projection of the buffer, and thus the buffer can also be kept operational, which in turn for correct operation of an automatic clutch is necessary.
  • the projection of the shock sleeve can be conveniently designed in the form of a flange either detachable to the push sleeve, e.g. by a threaded connection, or non-detachable, e.g. is attached by a welded joint.
  • the projection can also be in the form of a Shock sleeve firmly attached floor are formed, e.g. by a Shrink connection.
  • the push sleeve and the flange can also be in the form of a similar body are formed, e.g. as a single forging or casting.
  • the embodiment shown in Fig. 1 has a buffer tappet 1, which is on the front has a buffer plate 2.
  • the buffer tappet 1 is sliding inside a buffer sleeve 3 appropriate.
  • the buffer sleeve 3 is on the opposite side to the buffer plate 2 an end flange 4 ended.
  • the end flange 4 is with four screws 5 to a base plate attached.
  • a buffer spring 7 is used, which is from the front on the Buffer plate 2 supports and leans on the rear of the shock sleeve 8.
  • the shock sleeve 8 has on Front part on a projection 9.
  • the projection 9 is in the form of a flange 10 formed and fastened to the shock sleeve 8 by means of a welded connection.
  • the lead 9 can also, as shown in Figure 3, as a floor 11, which is by a Shrink connection is attached to the shock sleeve, are formed. Furthermore the projection 9, as shown in FIG. 2, can also take the form of a threaded flange 12 formed and attached to a threaded part 13 of the shock sleeve 8. Such a Projection can also be formed in another way, e.g. if the shock sleeve 8 is made out in the form of a single forging or casting, but what on the attached figures is not shown.
  • the projection 9 of the shock sleeve 8 is supported in the peripheral position of the buffer plunger 1 on the Butt surface 14 of this buffer tappet 1.
  • the butt surface 14 is by means of a nut 15 formed, which is attached to the buffer plate 1 opposite the buffer plate 2.
  • the part of the nut 15 aligned in the direction of the buffer plate 2 and the incision 16 on the inner side of the buffer sleeve 3 form a limiting means for the Longitudinal stroke movement of the buffer plunger 1, which is directed against the buffer carrier opposite the buffer sleeve 3.
  • a slot wedge 17 On the outer side of the buffer tappet 1 there is a slot wedge 17 provided, the part protruding from the buffer tappet in a groove 18, the is made longitudinally on the inner side of the buffer sleeve, is slidably attached.
  • the Groove wedge 17 and the groove 18 form a lock for the rotational movement of the Buffer tappet 2 opposite the buffer sleeve 3.
  • the cleat 20 has a locking projection 24 which together with the locking seat 25 located in the buffer tappet wall for locking the Buffer serves outside of its operating state.
  • the cleat 20 can along the End wall 21 of the carriage frame 22 can be moved.
  • the displacement of the cleat 20 is by means of a handle 26 connected to the cleat and a locking device 27 possible.
  • the locking device 27 is either by means of a weld seam or, as in FIG 2 shown, fastened to the push plate 20 by means of a screw connection.
  • the arm of the Latching device 27, shown in FIG. 1 and FIG. 6, has one in the form of a cuboid formed end piece 30.
  • the end piece 30 can be along a longitudinal opening 31, which in the base plate 6 is formed, and it can be the on position and off position of the buffer in the cutouts 32 and 33 are firmly fixed.
  • the locking device 27 from FIG. 2 has a differently designed end piece 34 equipped, which is shown in Figures 2, 4 and 5, and which has a bore 35.
  • the bore 35 can be a ratchet 36, which is in the form of a bolt or a screw is trained to record.
  • the locking mechanism 36 in the form as shown in FIG. is adjacent to the locking projection 37 or 38, on the buffer side of the base plate 6 used.
  • the locking projections are at the end points of a longitudinal opening 39 which in the Base plate 6 is formed, attached.
  • the locking mechanism 36 additionally in the bore 35 or 40, which in the locking projections 41 and 42 at the end points of the longitudinal opening 39 is introduced.
  • the abutment plate 20 In the operating state of the buffer, i.e. in the position of the buffer that is needed when the railway carriages are equipped with a screw coupling, the abutment plate 20 is applied the end wall 21 of the carriage frame 22 on (on position) and covers the End wall opening 23.
  • the abutment sleeve 8 abuts the abutment plate 20, the other side on the part of the buffer spring 7 located in the buffer plunger 1.
  • the Pressure load from the buffer plate 2 to the carriage frame 22 can be done in this way be transmitted.
  • the on position of the push plate 20 is with the end piece 30 or 34 set, the end piece 30 with the cleat 20 by the locking device 27th connected is.
  • the end piece 30 is then located on the one fixed via the cutout 32 Attitude.
  • this position is with the help of Latch projection 37 set such that in addition to this latch projection, the ratchet 36 is used.
  • that is End piece 34 determined with the help of the ratchet 36 such that the ratchet 36 both in the end piece 34 as well as in the bore 40 located in the locking projection 41 is used.
  • the opening should first 23 in the end wall 21 of the carriage frame 22 are cleared from the push plate 20.
  • the end piece 30 is left free, i.e. from section 32 pulled out.
  • a differently designed end piece 34 can be left free that the locking mechanism 36 is either pulled up via the locking projection 37 or from the bore 40 located in the locking projection 41 is pulled out.
  • the push plate 20 in the direction shown in FIG. 1 by an arrow moved to the position (off position) in which the end piece 30 or 34 is in the end position on the longitudinal opening 31 or 39.
  • the buffer plunger 1 pushed so far into the buffer sleeve 3 until the buffer plate 2 on the front part of the Buffer sleeve 3 bears (off position of the buffer).
  • the push plate 20 becomes the Buffer plunger 1 inserted.
  • the locking projection 24 of the buffer then penetrates into the Wall of the buffer plunger 1 made a lock seat 25.
  • the end piece 30 locked in the cutout 33 of the longitudinal opening 31.
  • the differently designed end piece 34 is determined with the help of the ratchet 36 located in the end piece such that the Lock 36 used next to the locking projection 38 on the buffer side of the base plate 6 becomes.
  • the end piece 34 is by means of the locking mechanism 36 so determined that the locking mechanism in both the end piece and in the Bolt projection 41 located hole 40 is used.
