Abstract:

A draft force sensor is provided for a coupling member coupled between a towing vehicle and a towed earth engaging implement, such as a scraper. The draft force sensor includes first and second bores extending through the coupling member. Each bore has a horizontal axis which extends perpendicular to a main fore-and-aft axis of the coupling member. The second bore is positioned above the first bore and spaced apart from the first bore. Each of the bores is surrounded by an outer cylindrical wall. Four electrical strain gauges are spaced apart and placed on the wall of each of the bores. A center line bisects an axis line which extends between the axes of the first and second bores. The axis of each bore is spaced apart from the center line by a distance which is less than a diameter of the bores. The strain gauges are connected electrically in a circuit which generates a draft force signal in response to draft forces applied to the coupling member.

Abstract:

A compact, planar, multi-directional vibration attenuator seat support permits attenuating movement of an attached seat in any direction within a horizontal plane in response to vibration and other motions. The seat support includes a thin, generally planar seat supporting frame having opposite sides which mount the opposite ends of a first plurality of rods slidably received within a first plurality of bearings coupled to the opposite ends of an intermediate frame so that the seat supporting frame is movable along a first axis relative to the intermediate frame. The intermediate frame which is substantially completely contained within the plane of the seat supporting frame has opposite sides mounting the opposite ends of a second plurality of rods slidably received within a second plurality of bearings which mount the entire seat support and which permit movement of the intermediate frame along a second axis perpendicular to the first axis. Shock absorbers damp movement of the seat supporting frame relative to the intermediate frame and movement of the intermediate frame relative to the second plurality of bearings, while opposed pairs of springs hold the seat supporting and intermediate frames in nominal center positions.
