Abstract
Abstract A mechanism for use on a tractor-trailer rig for automatically connecting and disconnecting the tractor-trailer service lines and the kingpin of a trailer to and from the fifth wheel of a tractor, and specifically the invention incorporates a system based on mutually attracting magnetic plates for automatically connecting and disconnecting the auxiliary service line connections, and incorporated therewith is a rotatable plate member serving to hold one of the magnetic plate members and also serving as a rotatable base for such magnetic plate member so that it can be aligned with the other magnetic plate member whenever the tractor and trailer are not aligned properly; and further included in this invention is an automatic system for raising and lowering the dolly wheels on the trailer as an integral part of the operation of the system.
