Definitions

  • the invention relates to a locking mechanism for a clutch arrangement according to the preamble of claim 1 and a clutch arrangement for Rail vehicles according to the preamble of claim 19.
  • DE 554 398 describes an automatic double clutch, especially for railway vehicles, known.
  • This double clutch is provided with a coupling member, the one longitudinally adjustable spindle with a thickened head having.
  • the other coupling member consists of two spring-loaded shell-shaped parts, which are secured in the closed position by a sleeve become.
  • the sleeve is in this way mounted on a spring in the longitudinal direction Spindle arranged that it can be moved against the action of a spring.
  • two pressure bolts are provided which, when the coupling is released, go over the front one Protrude at the end of the head. This for moving the sleeve when engaging provided pressure bolts are connected to a brake piston, which in a brake cylinder filled with liquid is received.
  • Double clutch For decoupling the Double clutch on each side two lever arrangements, by means of which one Gear and a rack to move the sleeve against the spring force can.
  • a disadvantage of such a double clutch is that it is complex is constructed and expensive to manufacture that it takes up a relatively large amount of space that a great deal of force has to be applied to decouple it.
  • the locking force reduced so far by means of the lever arrangement that the clutch arrangement can be unlocked manually even with high tensile loads.
  • the fact that the Latch of one coupling device from the other coupling device from the rest to the locking position and with the unlocking release lever unsecured is also movable back again, the two coupling devices one Coupling arrangement fully automatically coupled and after releasing the release lever also be uncoupled again.
  • Preferred embodiments of the locking mechanism are in the dependent Claims 2 to 18 circumscribed.
  • Claim 19 also claims a coupling arrangement for rail vehicles, whose two coupling devices, each with one of the preceding Claims trained locking mechanism are provided.
  • Preferred embodiments of the clutch arrangement are in the dependent Claims 20 to 29 circumscribed.
  • Fig. 1 shows the locking mechanism arranged on the coupling head 5 of a coupling device 1 in a partially sectioned illustration.
  • the locking mechanism 1 serves to secure two coupled coupling devices and essentially consists of a security body in Form of a bolt 2, an intermediate lever 3 and an unlocking lever 4. These three elements 2, 3, 4 together form a lever arrangement. Both the Latch 2 as well as the intermediate lever 3 and the unlocking lever 4 can be pivoted stored.
  • the axis of rotation of the bolt 2 is that with the reference numeral 20 of the intermediate lever 3 with the reference numeral 30 and that of the unlocking lever 4 provided with the reference numeral 40.
  • the intermediate lever 3 is a Spring 27 in a counterclockwise direction and the unlocking lever 4 via a spring 46 loaded clockwise.
  • the latch 2 has an actuating nose 21 and a locking projection on the front 22, while in the back a substantially concave Form recess 24 is embedded. This recess 24 goes in the area 25 facing the intermediate lever 3 from the concave in over a convex shape.
  • the latch 2 also has a further recess 26 on, which serves to lock the bolt 2 in the rest position.
  • the intermediate lever 3 has a roller 31, an extension 33 and one of one Projection 36 limited recess 35.
  • the extension 33 is on one side provided with a convex end face 34.
  • the unlocking lever 4 with a first cam 41 and one provided second cam 44.
  • the first cam 41 has a concave recess 42, which is in the form of the convex end face 34 of the intermediate lever 3 corresponds.
  • the second cam 44 has a tapered end face 45, which for cooperation with the recess 35 or the projection 36 of the intermediate lever 3 is determined.
  • the coupling head 5 itself has an oblique coupling surface on the coupling side 51, into which a recess 52 and a recess 53 is embedded.
  • oblique is to be understood to mean that the coupling surface 51 in the Effective state of the coupling device an angle ⁇ with the longitudinal central axis 6 of the rail vehicle to which the coupling device is attached is.
  • the coupling surface 51 closes an angle ⁇ of approx. 67.5 ° with the longitudinal central axis 6 of the rail vehicle when the coupling device is in the engaged state. Because of the size of this angle ⁇ can take into account the respective requirements and environmental conditions be worn.
  • the coupling surface 51 is on one side of one V-shaped coupling member 54 and on the opposite side of a corresponding recess 56 is limited.
  • FIG. 2 From Fig. 2 is a coupling device 7 in a side view and from the Fig. 3 can be seen in a plan view, in particular from the representation of FIG. 2 the V-shaped design of the coupling member 54 emerges.
  • a clutch assembly consists of two such coupling devices 7, which around Are rotated 180 ° about a vertical axis. Because the principal Operation of coupling arrangements for rail vehicles is known is, only the essential in connection with the invention Parts received.
  • the coupling head 5 of the coupling device 7 is via a damping device 8 is supported on a support arm 9.
  • the support arm 9 is via a bearing 11 attached to the rail vehicle (not shown).
  • the bearing 11 of the support arm 9 is provided with a hinge plate 17, in each of which there is a recess on both sides 18, 19 is embedded.
  • two spring-loaded, provided with rollers 13, 15 Levers 12, 14 are provided, their rollers 13, 15 in the recesses 18, 19th engage and support arm 9 in the rest position in a predetermined position hold.
  • the two recesses 18, 19 are asymmetrical in the hinge plate 17th recessed so that the support arm 5 in the rest position by about 2.5 ° compared to the Longitudinal central axis 15 of the rail vehicle is deflected.
  • the support arm 9 is in further provided with a hinge 10, by means of which, if necessary, folded and can be fixed to a locking arm 16.
  • Fig. 4 shows the initial state of the two for the coupling process in Direction of arrow P1, P2 coupling heads 5, 5a to be moved towards each other.
  • the locking mechanism 1 is due to the bias of the two springs 27, 46 in the rest position, so that the locking projection 22 in the recess 53 the coupling surface 51 is received and not via the coupling surface 51 protrudes.
  • the two coupling heads 5, 5a meet, as shown in FIG. 5, they move along the coupling surfaces 51, 51a until the Coupling members 54, 54a in the recess 56, 56a of the other coupling head 5, 5a engage and the respective latch 2, 2a on the actuating nose Twist 21, 21a clockwise against the spring force (Fig. 6).
  • the tensile force from the coupling member 54 is on the wall 57a of the respective recess.
  • the latch 2a only has to be a Take up the transverse component of the pending traction, its size, in addition to the absolute magnitude of the tensile force, due to the coefficient of friction between the side surfaces the coupling elements and the wall surfaces of the and the angle of the Side surfaces or the wall surfaces opposite the longitudinal central axis of the rail vehicle is determined.
  • the coupling arrangement has a high level of operational safety on.
  • the release of the latch 2, 2a is thereby enables or favors that the recess 24, 24a in the bolt 2, 2a in the area of a roller 31, 31a of the intermediate lever 3, 3a facing concave into a convex shape or a straight line.
