    摘要: A system and method of achieving ride control for a work vehicle that replaces a traditional accumulator with a ride control valve, a directional control valve and a fluid pressure source. The fluid pressure source may be a variable displacement hydraulic pump. The ride control valve is set to a first relief pressure that allows fluid to flow from the head end of a hydraulic cylinder when the loading on the cylinder, i.e., the pressure in the head end is equal to or greater than the first relief pressure. A work tool of the vehicle falls from a first position to a second position when fluid flows from the head end. The ride control valve is then reset to a second relief pressure, higher than the first relief pressure and sufficient to move the work tool toward the first position. Afterwards, the directional control valve is opened long enough to allow fluid from the fluid pressure source to enter the head end and move the work tool back to approximately the first position. The ride control valve may be dynamically adjusted.

    摘要: A boom position detecting device that detects a boom angle on a work vehicle for a boom that rotates about a pivot. The device includes a boom angle follower and positional sensor. The boom angle follower includes a spring and a follower arm arranged such that the spring biases the follower arm against a surface of the boom and keeps the follower arm in contact with the boom throughout a rotational movement of the boom about the pivot. The positional sensor is physically connected to the boom angle follower and detects at least one boom angle.
