- the mutual Andschreib vom 5 formed by the fact that on the coupling part 1, a pressure plate 12th is provided, which to corresponding counter-bearing surfaces 13 on the coupling part 2 in Plant can be brought.
- the inclination of the pressure plate 12 corresponds in the coupled state about the inclination of the Gegenandschreib modelling 13, so that upon actuation of the wedge connection a Mutual Verspannen between wedge connection and Andschreibdon is given, the additionally also has the effect that due to the inclination of the pressing surfaces 5 of the cross bar 8 is pressed into the hooks 9.
- a hydraulic piston-cylinder unit 15 is provided, which is arranged so that for insertion of the wedge bar 10 at the corresponding counter wedge surfaces 11, the hydraulic piston-cylinder unit in the sense of shortening the same is pressurized. This has the advantage that for opening a higher pressure can be used as for insertion of the wedge connection, with what possible Deadlocks can be prevented, or these jamming easier solved can be.
- Keilanlauf requirements 11 and the Jacobsburgsch requirements 13 is to be attached to the working tool coupling part 2 by Clutch plates 14,14 'formed, which with respect to the longitudinal center plane of the Working tool are arranged symmetrically.
- These coupling plates 14,14 ' stand parallel to each other and are attached to a support plate 18. Cross connections to Connection of the plates with each other are not provided.
- the two support plates 16th provided on the one hand, the eyelets 6,7 and on the other hand, the cross bar 8 for hanging of the coupling part 1 in the hook 9 of the coupling part 2, wherein the cross bar. 8 the two support plates 16 connects to each other and these on the outside on both sides surmounted. Furthermore, the two support plates 16, which are also parallel to each other run and symmetrical to the longitudinal center plane of the working tool and also the Knickebene the excavator boom are still arranged by the pressure plate 12th connected with each other.
- a connecting web 17th provided, which is attached via a central tab 20 on the cross bar 8 and of which on the side facing away from the tab 12 two mounting tabs 21 projecting are mounted, between which the hydraulic piston-cylinder unit 15th is pivotally mounted.
- the connecting tab 20 as well as the two Mounting tabs 21 are each cranked to the eyelets 6,7 out, causing the Longitudinal axis of the hydraulic piston-cylinder unit 15 approximately in the direction of movement of the Keilstabes 10 comes to rest.
- the wedge bar 10 is in the support plates 16 via Slots 23 out, and dominates the support plates on both sides of the outside.
- the Wedge surfaces on the wedge bar 10 are both at the between the support plates 16th located, these adjacent areas as well as on the support plates 16 outside provided for outstanding areas.
- the hydraulic piston-cylinder unit 15 engages on the wedge bar 10 in the middle, wherein the wedge rod 10 by a guide plate 22 in the axial Direction is led.
- the connection is made possible by any Wedge movements, e.g. Pivoting about its longitudinal axis, no moments on the hydraulic piston-cylinder unit are transmitted.
- the wedge bar 10 is formed as continuous, wherein it is in the region of Attachment of the hydraulic piston-cylinder unit fully, so circular held, on both sides of the articulation of the hydraulic piston-cylinder unit to a wedge surface flattened.
- this coupling part is also in relation to the vertical longitudinal center plane of the working tool formed symmetrically, i. that on each coupling plate a hook 9 to the opposite hook 9 'for the Hook connection 3 and corresponding counter-facing surfaces 11 'for the Wedge 4 and 13 'are provided for the system of the pressure plate 12.
- a bucket on the one hand for the deep operation with the Opening downwards or for high operation with the opening upwards, with and can be attached to the same coupling tool.
- clutch plates 19 are provided, which are formed and arranged congruently with the coupling plates 14, wherein the Distance between the plates 14 and 19 is dimensioned so that the support plates 16 of the Clutch parts 1 can intervene therebetween. It then engages the support plate 14 respectively in the located on the outer sides of the support plate 16 areas of the transverse bar 8, the Keilstabes 10 and the support plate 12, wherein the plates 19 at the on the inside of the Support plate 16 located areas of the transverse bar 8, the wedge bar 10 and the support plate 12 attack.
- FIG. 11 and 12 is for easy attachment provided, i. that the coupling part 2 with respect to the longitudinal center plane of the Work tool is not symmetrical, so that the relevant work tool only can be attached in a certain direction. Accordingly, each Clutch plate 14 of the coupling part 2 only a hook portion 9 and a Wedge contact surface 11 and contact surface 13 for the pressure plate 12 on.
- the additional Hook coupling plates 19 ' are provided only in the hook area but not in the Area of the wedge connection or pressure plate.
- the working tool differently directed, so twisted by 180 °, be coupled to the excavator boom, then it is done Coupling via the hooks 9 ', the wedge abutment surfaces 11' and the abutment surface 13 ', the hooks 9, the wedge abutment surfaces 11 and the abutment surface 13 without Function are.
