Description

[0001] The invention relates to a device, an energy carrier coupling, a coupling and a working machine according to the preambles of the independent patent claims.

[0002] Different devices for coupling a first energy coupling part of a work machine and a second energy coupling part of an attachment are known from the prior art.

[0003] For example, devices are known in which the first power coupling part and the second power coupling part dock only after the rotary movement of the work machine for picking up the attachment has been completed. This is then achieved with a wedge that presses the first power coupling part against the second power coupling part, thus establishing a connection. The disadvantage of such devices, however, is that the coupling process takes a long time and the wedge requires a lot of space. Furthermore, the wedge causes very high mechanical stress on the components during operation, since a very large angle is usually required to keep the size of the wedge as small as possible.

[0004] Furthermore, devices for coupling a first power coupling part of a work machine and a second power coupling part of an attachment are known from the prior art, wherein the first power coupling part and the second power coupling part are mounted in rubber. A disadvantage of such devices, however, is that these conventional devices can only compensate for a small angular offset between the first power coupling part and the second power coupling part and are therefore only suitable for large quick couplers. Furthermore, due to the resulting stresses, the rubber must be replaced frequently, as the rubber wears out, in particular the strength of the rubber changes, and may tear after several coupling processes. Furthermore, environmental influences, such as sunlight and / or contamination, also have a negative effect on the durability, in particular the strength, of the rubber.

[0005] The object of the invention is to overcome the disadvantages of the prior art. In particular, the object of the invention is to provide a device, an energy carrier coupling, a coupling and a work machine comprising the device, with which docking of the couplings, in particular the coupling of a first energy coupling part and a second energy coupling part, is possible without damage and / or with little damage and / or quickly. The object of the invention is, among other things, to provide a device, an energy carrier coupling, a coupling and a work machine comprising the device, which is robust and / or low-maintenance and / or low-wear, in particular can be operated cost-effectively, and has a long service life, in particular compared to conventional rubber couplings.
