Abstract

The invention concerns a lubricating system for a fifth-wheel traction coupling of a towing vehicle, comprising a coupling plate, the upper side of which has at least one grease discharge aperture which is connected to a lubricating device via a supply line fixed to the coupling plate. The invention addresses the problem of developing a lubricating system for towing vehicles which permits automatic lubrication irrespective of whether a central lubricating system is provided. The invention solves the problem using a lubricating system in which the lubricating device is associated with the fifth-wheel traction coupling and is arranged directly on the fifth-wheel traction coupling or in the vicinity of the fifth-wheel traction coupling.

Claims

1. A lubrication system for a fifth wheel traction coupling for a semi-trailer traction engine, including a coupling plate, whose upper side has at least one grease discharge aperture, connected by a supply line to a lubrication device mounted stationary to the coupling plate, wherein the lubrication device is associated with the fifth wheel traction coupling and directly installed to the fifth wheel traction coupling or installed in proximity to the fifth wheel traction coupling and contains a lubrication grease container as well as a feed pump.

2. A lubrication system according to claim 1, wherein the lubrication device is installed underneath the coupling plate.

4. A lubrication system according to claim 1, wherein the feed pump is controlled and operated by electronics.

5. A lubrication system according to claim 4, wherein the electronics communicate with an external control device.

6. A lubrication system according to claim 5, wherein the external control device is installed to the fifth wheel traction coupling.

7. A lubrication system according to claim 4, wherein the electronics and the control device communicate wirelessly with one another.

8. A lubrication system according to claim 1, wherein the lubrication device has a distributor.

9. A lubrication system according to claim 8, wherein the grease container, the feed pump and the distributor are integrated in one structural unit.

10. A lubrication system according to claim 1, wherein the lubrication device has a design, which is at least partly adapted to the contour of the fifth wheel traction coupling.

11. A lubrication system according to claim 1, wherein the lubrication device is manufactured as a plastic and/or metal component.

12. A lubrication system for fifth wheel traction couplings with a coated locking hook according to claim 1, wherein the coated locking hook is connected to the lubrication device by a supply line.
