Fifth wheel plate with a sliding plate having a top surface and a bottom surface. The sliding plate is detachably secured to the fifth wheel plate by at least one screw connection, the screw connection including a fastening means having a screw head and a threaded shank. The fifth wheel plate screw connection includes a form-fit element which bears against the bottom surface of the sliding plate and which has a form-fit means. The form-fit means cooperates with the sliding plate and forms a form-fit connection acting in the direction of a horizontal plane.

A fifth wheel includes a top plate having a throat that is adapted to receive a kingpin of a trailer. A pair of locking jaws are pivotally connected to the top plate and pivotal between a closed configuration where the pair of locking jaws block passage of a kingpin out of the throat and the locking jaws are held primarily in compression and an open configuration where a kingpin may pass into and out of the throat. Each of the pair of locking jaws has an engagement surface adapted to engage a kingpin positioned in the throat when the pair of locking jaws are in the closed configuration. A locking member is movably attached to the top plate and a mechanism urges the locking member into engagement with the pair of locking jaws when the pair of locking jaws are in the closed configuration.

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.

Systems for towing a trailer by a towing vehicle and a method for controlling such a system are disclosed. The systems and method are configured to maintain a constant towing load on the towing vehicle as well as optimizing other performance criteria such as fuel efficiency. The system comprises a closed loop controller, a towing arm assembly, a load measuring device, an electric hub motor, brakes, a motor controller and a brake controller disposed on the trailer. In another embodiment, two separate systems are installed, one on each side of the trailer. A load force feeds into a PID controller programmed with preset proportional, differential and integral parameters. The PID controller generates a command signal to either modulate the brakes or motor up or down depending on the sign of the command signal. A process output updates the system which continuously adjusts based on driving conditions.

The fifth wheel hitch lube plate of the present invention comprises a perforated support member having a plurality of perforations and a lubricious material molded around the perforated support member such that the lubricious material covers both the top and bottom surfaces of the perforated support member and extends through the perforations formed in the perforated support member. Preferably, the support member is a perforated metal plate and the lubricious material is nylon, graphite, or an ultra-high molecular weight (UHMW) polyethylene material. The problems associated with utilizing nylon (or similar materials) and bonding it to a support plate are overcome by forming the plurality of apertures in the support plate so that a mechanical cohesive bond is formed between the upper and lower surfaces of the support plate, thereby substantially increasing the lube plate strength, and shear strength, while decreasing the likelihood that the lube plate may buckle.
