Abstract: A load measuring hitch assembly is described. The assembly can include a body portion operable to facilitate coupling the load measuring hitch assembly to a tow vehicle. Additionally, the assembly can include a hitch ball coupled to the body portion. The hitch ball can include a ball operable to facilitate coupling the load measuring hitch assembly to a trailer. The hitch ball can also include a lower portion coupled to the body portion in a fixed relationship. The hitch ball can further include an instrument portion free to deflect due to at least one of a vertical or a horizontal force acting on the ball. In addition, the hitch ball can include one or more force sensors operably coupled to the instrument portion to measure a force on the instrument portion in at least one measurement axis, thereby facilitating determining a magnitude of the at least one of the vertical or the horizontal force acting on the ball.

Abstract: Load measuring hitch assemblies are disclosed and described. In one embodiment, the assembly can include a body portion operable to facilitate coupling the load measuring hitch assembly to a tow vehicle. The assembly can also include at least one load cell operable to measure force in at least one measurement axis. Additionally, the assembly can include a ball portion having a ball operable to facilitate coupling the load measuring hitch assembly to a trailer. The ball portion and the body portion can be coupled to one another via the at least one load cell and a pin slot joint. The pin slot joint can provide relative motion between the ball portion and the body portion in a rotational degree of freedom about a first axis and a translational degree of freedom along a second axis. The first and second axes can be orthogonal to one another.

Abstract: A weight measuring hitch ball assembly is described. The assembly can include a hitch ball having a ball and a lower portion. The assembly can also include a body portion defining a hitch ball opening that slidably receives the lower portion of the hitch ball. The assembly can further include a load measurement device operably associated with the body portion and the hitch ball to determine a magnitude of a force acting on the hitch ball. Additionally, the assembly can include a retention coupling operable with the hitch ball and the body portion to secure the hitch ball to the body portion. The retention coupling can have a retention protrusion and a retention wall defining at least a portion of a retention opening operable to receive at least a portion of the retention protrusion therein. With the retention protrusion extending into the retention opening, the retention wall can provide a mechanical barrier to the retention protrusion that prevents removal of the hitch ball from the hitch ball opening.

Abstract: A hitch ball assembly for a trailer hitch. The hitch ball assembly includes a clam-shaped body having a plurality of hinged segments operable between an open position and a closed position. Each of the plurality of hinged segments includes a concave inner surface that collectively form a ball shaped-cavity configured to enclose a smaller-diameter hitch ball. Each of the hinged segments further includes an outer surface that collectively form a larger-diameter hitch ball configured to engage a trailer tongue when the hinged segments are operated to the closed position.

Abstract: A spring bar coupling device is described for coupling a spring bar of a weight distributing trailer hitch to a trailer frame. The spring bar coupling device can include a spring bar support operable to interface with and support a spring bar of a weight distributing trailer hitch. The spring bar support can have a vertical support arm having a first coupler opening, and a lower spring bar stop extending from the vertical support arm to provide a lower interface for the spring bar. The spring bar coupling device can also include a channel bracket having at least two opposing walls defining a vertically oriented channel operable to receive the vertical support arm, and a second coupler opening in at least one of the two walls. The first and second coupler openings can be configured to be aligned with one another at a first coupling location when the vertical support arm is located at least partially within the vertically oriented channel.

Abstract: A weight distributing trailer hitch and associated method are described. The weight distributing trailer hitch can include a hitch portion for interfacing with a hitch receiver associated with a vehicle. The weight distributing trailer hitch can also include a ball portion to facilitate coupling with a tongue of a trailer. In one embodiment, the weight distributing trailer hitch can further include a spring bar vertically pivotal relative to the hitch portion, and an adjustment mechanism actuatable to selectively adjust a tilt angle of the spring bar relative to the hitch portion to vary preload on the spring bar and adjustably distribute weight of the trailer relative to the vehicle. In another embodiment, the weight distributing trailer hitch can further include a spring bar for distributing weight of the trailer relative to the vehicle, and a load measurement device to determine a magnitude of a downward force on the hitch ball.
