The invention relates to a trailer coupling for a motor vehicle (11), in particular a passenger car, comprising a retainer (20), which is arranged on or can be fastened to the motor vehicle (11), and a retainer part (30), which can be detachably fastened to the retainer (20) and which has a retainer insertion projection (33) for inserting into a retainer insertion receptacle (24) of the retainer (20), wherein the retainer part (30) has an integrated locking device (70) having at least one locking body (71) and has an actuation body (73), which is supported in the retainer part (30) so as to be movable in order to actuate the at least one locking body (71) into a locking position (R), wherein the at least one locking body (71) interlockingly engages in a locking receptacle (72) on the retainer (20) in the locking position (R) and is moved out of the locking receptacle (72) in a detaching position (L), the retainer insertion projection (33) of the retainer part (30) therefore being interlockingly locked in the retainer insertion receptacle (24) of the retainer (20) in the locking position (R) of the at least one locking body (71) and being removable from the retainer insertion receptacle (24) of the retainer (20) in the detaching position (L), wherein the retainer part (30) is provided for forming a coupling arm (15), which has a coupling part (60) having a coupling element (65), in particular having a coupling ball, for coupling a load carrier (200) or a trailer, or is provided for directly coupling a load carrier (200). According to the invention, the retainer part (30) has a receiving sleeve (40) having a tubular coupling insertion receptacle (41) for inserting a coupling insertion projection (66; 266) of the coupling part (60) or of the load carrier (200).

An coupling apparatus for towing is provided which in some embodiments may be a ball hitch coupler configured to accept a ball hitch which is attached to a towing vehicle. The apparatus may include one or more projections that may be flat-topped with rounded corners and separated by valleys having a tapered profile. This configuration reduces and transfers stress away from the connection point of a mounting section, such as a removable tube which is then attached the towed vehicle. The apparatus may be sized and shaped so as to accept a multitude of different styled and shaped mounting sections. The projections sit atop a flange that may be configured to reduce the compression load on the apparatus. The apparatus may utilize a clamping force style fastener to be used to attach the mounting section to the apparatus, providing for maximum versatility of said apparatus.

An electric scooter hitch assembly is configured to be quickly attached to and removed from an electric scooter. The hitch assembly provides a mechanism for selectively securing a carry-on or other towable item to a variety of electric scooters. The hitch assembly is compact and easily transportable thereby making it an ideal solution for a rider to temporarily adapt an electric scooter, including rental electric scooters, to transport towable items such as trailers, luggage, carts, or other suitable items.

A multiple hitch assembly and method of use thereof including a hitch platform having a channel member and multiple hitch member having a block base. A dampening member may be affixed such that coupling of the multiple hitch member by locked engagement of received through holes of the block base and paired side holes disposed in flanges of the channel member compresses the dampening member upon the recessed column of the hitch platform to absorb and thus attenuate the load and associated torque imparted by movement and rub between the hitch platform and multiple hitch member to thereby reduce associated rattle noise, and vibration.

A king pin adaptor is provided for allowing a king pin, intended to connect to a fifth wheel hitch, to be attachable to a ball hitch assembly. A hitch assembly is provided having a plurality of vertical and longitudinal positions for securing a ball member to allow for greater flexibility in attaching to various towed structures. The king pin adaptor and hitch assembly may be used alone or together as components of a towing system for towing a trailer with a king pin or ball mount.

In an embodiment a towing pipe connection structure includes a vehicle body rear member including an aluminum material, a towing pipe at least partially including an aluminum material and a connection bracket including a bumper back beam plate in contact with a back panel of a vehicle body and including an insertion hole into which the towing pipe is inserted, an engage plate having an engage hole to which the towing pipe is connected and a connection plate connecting the bumper back beam plate and the engage plate, wherein the connection bracket is connected to a rear member of the vehicle body, and wherein the connection bracket includes an aluminum material.

A gooseneck ball extender is designed to mate with a center socket and receivers mounted to a towing vehicle and provide a gooseneck ball that is offset from the center socket. The extender has a cylindrical shaft with captured balls that can be moved between a retracted position and an extended position through a spring-loaded locking shaft that moves between an unlocked and locked position. The locking shaft is biased towards the locked position where the captured balls are extended. The extender has an outrigger portion that has puck locks. The puck locks are rotatable between a locked position and an unlocked position. As attached to the towing vehicle, the outrigger portion provides additional support to the gooseneck ball.
