A fifth wheel hitch assembly for mounting to a towing vehicle and receiving a kingpin of a trailer incorporating a comfort assembly is provided. The fifth wheel hitch assembly may comprise a kingpin receiving assembly attached to a mounting rail via a comfort assembly. The comfort assembly may include one or more pivot bushing assemblies, as well as vertically adjustable, anti-rattle attachment systems. These attachment systems may include a cam assembly and/or a T-pin assembly.

A fifth wheel configured to reversibly couple a trailer to a tractor including a coupling plate configured to receive a journal element of the trailer and a bearing block configured to pivotably bear the coupling plate about a pivot axis, in particular about a horizontally extending pivot axis, at least one distance sensor being provided which determines a distance with respect to a reference surface, the at least one distance sensor and/or the reference surface being arranged as part of the bearing block or on the bearing block.

A security lock system for a fifth wheel hitch is system that restricts access to the connection between a fifth wheel hitch and a truck bed. The system includes a receiver lock, a fifth wheel hitch, a first sleeve, a second sleeve, a lock engagement channel, and a key. The receiver lock shields a securing mechanism of the fifth wheel hitch. The receiver lock connects with a base frame of the fifth wheel hitch through the lock engagement channel. The first sleeve and the second sleeve uphold the receiver lock against the lock engagement channel. A retractable locking bolt and a locking assembly are connected to each other with the key. The retractable locking bolt and the locking assembly remain stationary as the retractable locking bolt includes a first tubular body and a first stopper, and the locking assembly includes a second tubular body and a second stopper.

A coupling plate for a fifth wheel coupling, wherein the coupling plate on a top side includes a planar bearing surface and at a rear end it includes two entrance horns bordering on an entrance opening, the entrance opening extends in a longitudinal axis (x) of the coupling plate and ends in a kingpin bearing region, and the coupling plate is configured with a respective receiving structure for a bearing block on its bottom side, on either side of the kingpin bearing region and spaced apart from each other on a transverse axis (y). The problem which the invention proposes to solve is to provide a standardized coupling plate, having a minimal natural weight, given a slight loading, and whose strength can be adapted for higher anticipated loads. The problem is solved according to the invention in that at least one connection means for the releasable mounting of at least one stiffening element is formed on the coupling plate beneath the planar bearing surface.

The present disclosure relates generally to a fifth wheel hitch and, more particularly, to a fifth wheel hitch having a latching system that is viewable to a user. In another instance, the present disclosure relates to a fifth wheel hitch having a latching system that permits a user to restrict movement of the fifth wheel hitch in at least two different planes of motion.

A shock absorbing pin box system includes a first sidewall, a second sidewall, an upper wall, a lower wall, and a kingpin. The first sidewall defines at least a first plurality of apertures arranged in first column, and the second sidewall defines at least a second plurality of apertures arranged in a second column. A plurality of tubes extend from each of the first plurality of apertures and the second plurality of apertures. A plurality of flexible and resilient tubular bushings are received in a corresponding one of the plurality of tubes. A plurality of bolts are received within corresponding ones of the pluralities of apertures of the pin box and the plurality of tubes.

A truck towing system is described. The truck towing system provides for a first truck to tow a second truck in a back to front relationship, i.e., the front portion of the second truck (the towed truck) is connected or attached to a rear portion of the first truck (the towing truck). The truck towing system includes an upper member to connect with a first truck. A middle member joins the upper member and a lower member in a fixed engagement. The lower member supports a front portion of a second truck. A beam member is engaged to the lower member. The beam member connects to a rear portion of the second truck.

An adjustable trailer hitch and king pin assembly that may be moved longitudinally to adjust the position and weight distribution of a trailer relative to a truck. The disclosed assembly may allow a trailer to be utilized with various different sized and configured trucks while maximizing the cargo carrying capability and efficiency thereof. In one example, an adjustable trailer hitch is provided having a slidable king pin assembly that may be adjusted forwards or backwards to move the king pin to the desired location relative to the truck and trailer. In another example, a removable king pin may be provided that may be removed and moved to a different location according to the weight and desired weight distribution of a truck and trailer combination.

A fifth wheel hitch is shown and described. The fifth wheel hitch may include a base frame configured to be secured to a load bed of a towing vehicle, a trolley operatively engaged with the base frame, the trolley adapted to move along the base frame between first and second positions, and a cam member attached with the base frame, the cam member having a cam path. The fifth wheel hitch may also include a cam follower coupled with the trolley, the cam follower operatively engaged with the cam path, and a fifth wheel head pivotally coupled with the trolley, where the trolley is moved between the first and second positions in response to pivoting of the fifth wheel head.
