System for lubricating a closing mechanism, a closing bar and closing hook
The invention relates to a system for lubricating a closing mechanism on a saddle coupling comprising a closing mechanism which is arranged on the lower side of a coupling plate and which comprises at least one closing hook and/or closing bar, provided with a coating, and a fat reservoir which is connected to the closure hook by means of a lubricating line. The invention also relates to a coating of individual components of the system, i.e. the closing hook and the closing bar, in addition to the use of a coating. The invention is characterized in that the coating of the closing hook and/or the closing bar is embodied as a sliding coating.
1. A system for lubricating a closing mechanism on a fifth wheel comprising: the closing mechanism arranged on a bottom side of a coupling plate, the closing mechanism having at least one closing hook provided with a permanent coating, and a grease reservoir having only one lubricating line exiting the grease reservoir, wherein the lubricating line is solely connected to the closing hook such that grease is distributable from the lubricating line directly onto a contact surface of the closing hook which contacts a kingpin when the kingpin is present, wherein the coating of the closing hook is configured as a sliding coating and the grease reservoir is a grease cartridge, with the grease cartridge arranged on the fifth wheel.
2. The system per claim 1 , wherein the grease cartridge is coordinated with the fifth wheel.
3. The system per claim 2 , wherein the grease cartridge is arranged underneath the coupling plate and has a drive unit that comprises an electromechanical drive or a chemical drive, wherein the drive unit is connected to a variable control mechanism that interacts with a valve control mechanism, or a flow restriction valve arranged in the lubricating line, wherein the variable control mechanism communicates with a control unit, or with a pressure sensor arranged on the coupling plate.
4. The system per claim 1 , wherein the grease cartridge is arranged underneath the coupling plate.
5. The system per claim 1 , wherein the grease cartridge has a drive unit.
6. The system per claim 5 , wherein the drive unit comprises an electromechanical drive.
7. The system per claim 5 , wherein the drive unit comprises a chemical drive.
8. The system per claim 5 , wherein the drive unit is connected to a variable control mechanism.
9. The system per claim 8 , wherein the variable control mechanism interacts with a valve control mechanism.
10. The system per claim 9 , wherein the valve control mechanism comprises a flow restriction valve arranged in the lubricating line.
11. The system per claim 8 , wherein the variable control mechanism communicates with a vehicle control unit.
12. The system per claim 8 , wherein the variable control mechanism communicates with a coupling control unit.
13. The system per claim 8 , wherein the variable control mechanism communicates with a pressure sensor arranged on the coupling plate.
14. The system per claim 1 , wherein at least one outer surface of the closing hook is provided with the coating, wherein the coating is in the form of the sliding coating.
15. The system per claim 14 , wherein the sliding coating consists of a multilayer system.
16. The system per claim 15 , wherein the multilayer system is composed of at least a first layer, which comprises an iron alloy with nickel and molybdenum fractions, and a second layer of PTFE, applied to the first layer.
17. The system per claim 14 , wherein the sliding coating has a layer thickness of 50 to 150 μm.
18. The system per claim 17 , wherein the sliding coating has a layer thickness of 70 to 130 μm.
19. The system per claim 1 , including a closing bar for use in the fifth wheel, wherein at least one outer surface of the closing bar is provided with the coating, wherein the coating is in the form of the sliding coating.
20. A system for lubricating a closing mechanism on a fifth wheel comprising: the closing mechanism arranged on a bottom side of a coupling plate, the closing mechanism having at least one closing hook provided with a permanent coating, and a grease reservoir having only one lubricating line exiting the grease reservoir, wherein the lubricating line is solely connected to the closing hook, wherein the coating of the closing hook is configured as a sliding coating, wherein the grease reservoir is a grease cartridge, with the grease cartridge arranged on the fifth wheel, and wherein the closing hook comprises a lubricating channel expiring on a contact surface which contacts a kingpin when the kingpin is present.
21. A system for lubricating a closing mechanism on a fifth wheel comprising: the closing mechanism arranged on a bottom side of a coupling plate, the closing mechanism having at least one closing hook provided with a permanent coating, and a grease reservoir having only one lubricating line exiting the grease reservoir, wherein the lubricating line is solely connected to the closing hook, wherein the coating of the closing hook is configured as a sliding coating, wherein the grease reservoir is a grease cartridge, with the grease cartridge arranged on the fifth wheel, and wherein the closing hook comprises a lubricating channel running in a radial direction and expiring on a contact surface which contacts a kingpin when the kingpin is present.
22. A system for lubricating a closing mechanism on a fifth wheel comprising: the closing mechanism arranged on a bottom side of a coupling plate, the closing mechanism having at least one closing hook provided with a permanent coating, and a grease reservoir having only one lubricating line exiting the grease reservoir wherein the lubricating line is solely connected to the closing hook, wherein the coating of the closing hook is configured as a sliding coating and the grease reservoir is a grease cartridge, with the grease cartridge arranged on the fifth wheel, and wherein the closing hook comprises a lubricating channel running in a radial direction on one side of the closing hook opposite a closing opening.
