Definitions

  • the present invention relates to a clutch system according to the preamble of claim 1.
  • Coupling systems for interchangeably coupling an attachment to a working machine are known from the prior art, with the respective coupling system having a main coupling part for connection to the working machine and a secondary coupling part for connection to the attachment.
  • an attachment in the form of an excavator shovel can be mechanically coupled to a work machine in the form of an excavator boom.
  • this arrangement of the hydraulic couplings is relatively susceptible to damage, despite any protective plates that may be present, since the hydraulic couplings can usually hardly be seen by the user of the working machine.
  • the respective attachment can be connected to the secondary coupling part in a manner known per se, for example by means of a screw connection.
  • the main coupling part according to the invention can be mechanically coupled to known secondary coupling parts without hydraulic couplings—and thus also to attachments attached to such secondary coupling parts, such as excavator shovels.
  • transverse, longitudinal and normal directions are defined by the main coupling part with its longitudinal axis parallel to the longitudinal direction.
  • these directions could also be referred to as "transverse direction of the main coupling part", “longitudinal direction of the main coupling part” and "normal direction of the main coupling part”.
  • the latter extends parallel to the transverse direction.
  • the contact surface also extends parallel to the transverse direction in order to enable the fastening element, in particular the second fastening bolt, to rest stably on the contact surface.
  • the movement of the locking slide does not have to be exactly parallel to the longitudinal direction, theoretically not even a linear movement is necessary. Only the main directional component of the movement of the locking slide must be parallel to the longitudinal direction, ie if one or more directional components parallel to the transverse direction and/or normal direction is/are present, these must/must be smaller than the main directional component.
  • the movement of the hydraulic coupling unit does not have to be exactly parallel to the longitudinal direction, theoretically not even a linear movement is necessary. Only the main directional component of the movement of the hydraulic clutch unit has to be parallel to the longitudinal direction, i.e. if one or more directional components parallel to the transverse direction and/or normal direction are also present, these must be smaller than the main directional component in terms of absolute value.
  • a first drive means preferably a pneumatic or electric or hydraulic cylinder
  • a second drive means preferably another pneumatic or electric or hydraulic cylinder
  • the two drive means in particular the hydraulic cylinder and the additional hydraulic cylinder, are also one behind the other as seen in the normal direction arranged to enable a particularly space-saving solution.
  • a control for the movement of the locking slide and the hydraulic clutch unit of the main clutch part is provided, which is set up to move the hydraulic clutch unit of the main clutch part from the uncoupling position into the coupling position only when the locking slide is in the locking position, and to move the locking slide from the locking position to the release position only when the hydraulic coupling unit of the main coupling part is in the uncoupling position.
  • a hydraulic coupling is also carried out only if there is a perfect mechanical coupling between the main coupling part and the secondary coupling part, which in turn can prevent damage to the hydraulic couplings.
  • the hydraulic couplings of the main coupling part have a well-defined position with a perfect mechanical coupling, so that a secure connection with any hydraulic couplings that may be present on the side of the secondary coupling part can be guaranteed.
  • the base body can have, for example, two opposing plate-shaped sections, in each of which one of the groove-shaped guide surfaces of the guide for the locking slide is arranged.
  • the main clutch part comprises a base body which has a guide for the hydraulic clutch unit of the main clutch part , wherein the hydraulic coupling unit of the main coupling part is accommodated at least in sections in opposing groove-shaped guide surfaces of the guide.
  • the base body can have, for example, two opposing plate-shaped sections, in each of which one of the groove-shaped guide surfaces of the guide for the hydraulic clutch unit is arranged.
  • the first direction, the second direction, and the third direction are defined by the slave clutch portion with its longitudinal axis parallel to the second direction.
  • these directions could also be referred to as “first direction or lateral direction of the sub coupling part", “second direction or longitudinal direction of the sub coupling part” and “third direction or normal direction of the sub coupling part”.
  • the arrangement of the hydraulic coupling unit of the secondary coupling part allows the hydraulic connection or coupling to the main coupling part or to its at least one hydraulic coupling, with the positioning of the hydraulic couplings on the hydraulic coupling units being coordinated accordingly.
  • a coupling of the hydraulic couplings of the main coupling part and the secondary coupling part is thus made possible when the main coupling part and the secondary coupling part are mechanically coupled and the hydraulic coupling unit of the main coupling part is in the coupling position.
  • the longitudinal direction of the main coupling part is parallel to or coincides with the second direction of the sub coupling part.
  • the hydraulic couplings of the secondary coupling part it is not mandatory for the hydraulic couplings of the secondary coupling part to be oriented parallel to the second direction, since ultimately the movement of the hydraulic coupling unit of the main coupling part is decisive, which in turn does not need to be exactly parallel to the longitudinal direction of the main coupling part. Accordingly, it is in a preferred Embodiment of the clutch system according to the invention provided that the second direction and a longitudinal axis of the at least one hydraulic clutch of the secondary clutch part enclose an angle of at most 10 °, preferably at most 5 °.
  • the angle specifications are to be understood as absolute values, ie the exact alignment, in particular whether upwards or downwards, of the second direction and the longitudinal axis of the at least one hydraulic clutch of the secondary clutch part relative to one another is not important.
  • At least one guide pin is provided which protrudes from the hydraulic clutch unit of the secondary clutch part parallel to the longitudinal axis of the at least one hydraulic clutch of the secondary clutch part and points in the second direction.
  • the guide pin can, for example, be inserted into a corresponding recess in the hydraulic coupling unit of the main coupling part when the hydraulic coupling unit of the main coupling part moves from the decoupling position into the coupling position. This achieves a precise alignment of the two hydraulic coupling units and thus the associated hydraulic couplings during this movement, so that the hydraulic couplings are reliably coupled.
  • a preferred embodiment of the clutch system according to the invention provides for the hydraulic coupling unit of the secondary coupling part to be elastic is mounted, preferably by means of at least one damping plate made of rubber or plastic.
  • the hydraulic coupling unit of the secondary coupling part is mounted, preferably by means of at least one damping plate made of rubber or plastic.
  • the latter can be supported, for example, by the at least one guide pin mentioned above.
  • the hydraulic clutch unit of the secondary clutch part can comprise several, preferably five, hydraulic clutches. These hydraulic couplings do not have to be arranged linearly next to one another in the hydraulic coupling unit of the secondary coupling part, but can also be arranged partially parallel to the third direction, offset from one another—corresponding to the positions of the hydraulic couplings of the main coupling part.
  • the hydraulic clutch unit of the secondary clutch part has at least one hydraulic line connection, the at least one hydraulic line connection being in fluid communication with the at least one hydraulic clutch of the secondary clutch part and pointing to the reference plane.
  • At least one hydraulic line connection can be connected to at least one hydraulic line connection in order to at least one to supply the hydraulic drive of the attachment with hydraulic oil.
  • the orientation of the at least one hydraulic line port is substantially normal to the orientation of the associated hydraulic coupling.
  • the hydraulic oil is correspondingly diverted in the hydraulic clutch unit of the secondary clutch part by approx. 90° - typically in the direction of the hydraulic drive to be supplied. Since compact dimensions of the hydraulic coupling unit of the secondary coupling part are typically provided, the resulting geometry—with a relatively narrow radius—can be a hindrance for the path to be covered by the hydraulic oil, with very high flow rates of the hydraulic oil.
  • the hydraulic clutch unit of the secondary clutch part has at least one hydraulic high-flow line connection, the at least one hydraulic high-flow line connection being in fluid communication with the at least one hydraulic clutch of the secondary clutch part and points substantially in the second direction.
  • the at least one high-flow hydraulic line connection can be provided as an alternative or in addition.
  • the orientation of the at least one high-flow hydraulic line connection is essentially analogous to the orientation of the corresponding hydraulic coupling of the secondary coupling part.
  • a longitudinal axis of the high-flow hydraulic line connection can also enclose the same angle with the second direction as the longitudinal axis of the corresponding hydraulic clutch. Due to this orientation, there is no deflection of the hydraulic oil between the corresponding hydraulic coupling and the hydraulic high-flow line connection within the Hydraulic coupling unit of the sub-coupling part, which allows very high flow rates. Any necessary diversions can be made generously - with separate lines with large radii - outside of the hydraulic clutch unit.
  • the at least one hydraulic clutch of the main clutch part can be fluidically coupled to the at least one hydraulic clutch of the secondary clutch part by moving the hydraulic clutch unit of the main clutch part into the coupling position when the main clutch part and the secondary clutch part are mechanically coupled.
  • the uncoupling is correspondingly achieved by moving or transferring the hydraulic coupling unit of the main coupling part into the uncoupling position.
  • FIG. 1 shows in an axonometric view obliquely from above a main coupling part 1 for a coupling system for interchangeably coupling an attachment to a working machine.
  • 2 shows the main coupling part 1 in an axonometric view obliquely from below.
