摘要： A weight distributing hitch assembly for towing a trailer behind a towing vehicle includes a ball mount head, a pair of spring bars, a pair of adjustable length cam arms for supporting projecting ends of the spring bars, a pair of lift units carried on the trailer and a pair of lift chains extending between the cam arms and the lift units. The projecting ends of the spring bars include a cam follower and the distal ends of the cam arms include cooperating cams that function to provide trailer sway control.

摘要： A bracket, apparatus and method are provided for adapting a simple draw bar and hitch ball arrangement to allow connection to a sway control device. The bracket includes an aperture for receiving the threaded stem of the hitch ball, a notch for receiving and engaging the draw bar and a second aperture for receiving a sway control device connector such as a sway control ball. The bracket allows connection to any number of sway control devices available in the industry so that a simple draw bar and hitch ball may be converted for sway control capability.

摘要： A side strut (5) for a lower steering arm of a tractor has a single-action hydraulic cylinder and a setting unit with a hollow cylinder (17) and an adjustable setting element 20. The setting element (20) includes a threaded bore (30) which receives a threaded rod (32). The hydraulic cylinder has a first attaching element (6) to connect to a tractor. The threaded rod (32) has a second attaching element (7) to connect a lower steering arm. In the fully moved-out position of the hydraulic cylinder, the setting element (20) is rotatable by an actuating lever (33). Thus, the threaded rod (32) moves in and out. To prevent any rotation, a first holding element (36) is provided. The actuating lever (33) engages the holding element in a rest position. A second holding element (37) is provided to ensure, in those cases where the hydraulic cylinder is in a position other than the fully moved-out position, that the actuating lever (33) is held to prohibit a rotational movement of the setting element (20) relative to the hollow cylinder. The rotational movement would effect a change in the length setting.

摘要： An apparatus for reducing the sway of a trailer includes a first portion that is attached to a towing vehicle at any of several locations including an end portion of a receiver hitch, a bumper, a frame or body member, or by the use of a modified type of a drawbar having an offset member. A second portion is attached to a trailer at any of several locations including to a ball coupler by the use of an adapter plate, a modified ball coupler bracket, or directly to a tongue of the trailer. Intermediate the first and second portion at least one damper is disposed, preferably a hydraulic damper of the type that is generally used to form an automobile steering damper. The damper preferably includes spherical type bearings at each end thereof to allow for limited articulation about a point. A geometric arrangement (i.e., an angle) for the damper is provided whereby a sufficient dampening force is experienced the moment the trailer begins to deviate from normal. Alternative embodiments are described that increase the number of the hydraulic dampers that are utilized or affect the resistance they provide.
