An adjustable bracket assembly for a weight distribution system is shown and described herein. The adjustable bracket assembly may include a plurality of bracket members including at least a first bracket member, a second bracket member, a third bracket member, and a fourth bracket member arranged to be adjustable relative to one another and be selectively attached to a frame of a towed vehicle. The plurality of bracket members may be coupled to a plurality of fasteners to allow the plurality of bracket members to be adjusted relative to one another and to provide clamp forces relative to the frame of the towed vehicle. An attachment assembly may be coupled to the first bracket member and be configured to be attached to a spring arm of a weight distributing system that may be coupled to a towing vehicle.

A weight distributing hitch assembly for towing a trailer behind a towing vehicle is disclosed having spring arms pivotally mounted to a hitch head so that the distal ends of the spring arms may be rotated downward relative to a spring arm support mounted on a side of the trailer for loading the spring arm on the spring arm support. The spring arms are preferably rotated using an actuator connected between the hitch head and at least one of the spring arms for applying a downward rotational force on the spring arm relative to said spring arm support.

A hitch system comprising a hitch shaft with a forward end configured to rigidly attach to a tow vehicle and a rearward end extending rearwardly toward a trailer frame; a head unit pivotally attached to the rearward end of the hitch shaft at a first pivot point having an upper portion and a lower portion, comprising a hitch ball on the upper portion of the head unit positioned out of vertical alignment with the first pivot point creating a second pivot point between the hitch ball and a trailer attached thereto; and a slot on the lower portion of the head unit, the slot having portions in vertical alignment with the first pivot point and the second pivot point; a first moment arm with a distal end configured for slidable attachment to a first bracket on the trailer frame and a forked proximal end comprising a first tine pivotally connected to the lower portion of the head unit; and a second tine having a knob in a sliding connection with the slot; and a second moment arm with a distal end configured for slidable attachment to a second bracket on the trailer frame and a proximal end pivotally attached to the head unit; wherein the first moment arm is at a first angle relative to the member of trailer and the second moment arm is at a second angle relative to the trailer; wherein the first angle is greater than the second angle; and whereby the effective pivot point of the system is moved forward to reduce sway is disclosed.

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.

A weight distribution system used with a hitch on a vehicle and a trailer, the weight distribution system comprising a moment bar with a forward end attached to the hitch so as to pivot about a generally vertical axis, the moment bar extending rearwardly along a center longitudinal plane of the trailer toward a rearward portion, the moment bar configured to exert a forward moment on the vehicle in response to an upward force on the rearward portion; a bracket attached to a trailer frame element, wherein the bracket is above the first rearward portion and further from the center longitudinal plane of the trailer than the rearward portion; and a tension member combined with a tension mechanism so as to increase and decrease a tensile force between the bracket and the rearward portion, to thereby increase and decrease the upward force on the rearward portion whereby sway of the trailer is reduced by biasing the system back to the centerline when the vehicle and trailer are out of alignment is disclosed.

A weight distribution hitch system comprising a vehicle attachment member comprising a forward end configured to rigidly attach to a vehicle, and a rearward end extending rearwardly toward a trailer, the rearward end comprising an upper portion comprising a trailer attachment member configured to pivotally attach to a coupler of the trailer, and a lower portion configured to receive a moment bar; a moment bar comprising a moment bar forward end attached to the lower portion of the rearward end of the vehicle attachment member so as to prevent rotation about a horizontal axis, and a moment bar rearward end; a tension member comprising a top end configured to be supported by a frame member of the trailer, and a bottom end configured to support the rearward end of the moment bar, and a spring, configured to bias the moment bar rearward end toward the frame member of the trailer; and wherein, when the tension member is in tension, it imposes an upward force on the moment bar rearward end, which, in turn, imposes a forward moment on the vehicle is disclosed.

A weight distribution hitch system comprising a vehicle attachment member comprising a forward end configured to rigidly attach to a vehicle, and a rearward end extending rearwardly toward a trailer, the rearward end comprising an upper portion comprising a trailer attachment member configured to pivotally attach to a coupler of the trailer, and a lower portion configured to receive a moment bar; a moment bar comprising a moment bar forward end attached to the lower portion of the rearward end of the vehicle attachment member so as to prevent rotation about a horizontal axis, and a moment bar rearward end; a tension member comprising a top end configured to be supported by a frame member of the trailer, and a bottom end configured to support the rearward end of the moment bar, and a spring, configured to bias the moment bar rearward end toward the frame member of the trailer; and wherein, when the tension member is in tension, it imposes an upward force on the moment bar rearward end, which, in turn, imposes a forward moment on the vehicle is disclosed.
