`
`If all legs are at different positions, and the operatorraises the left side, the system will
`movethe right legs at the same speed in opposite directions to get them to the same
`displacement(in test case, front right lowered andrearright raised), while at the same
`time continuesto raise the left legs at different speeds so that they are at the same
`displacementby the time the right legs have reached the same displacement. Summary —
`system is always driving legs so that both right legs are at the same displacement, and
`both left legs are at the same displacement, regardless of what the operator commands.
`Are there othertest cases that prove this out?
`
`4-fold Full-Floating Axles —
`This feature is accomplishedstrictly based on the hydraulic plumbing of the system. This
`occurs naturally and does not require any valve commands. Whenoneleg cylinder
`moves due to an obstacle, the cylinders adjacent to it will move in the opposite direction,
`and the cylinder opposite it will move in the same direction. The right rear andleft front
`cylinders are always moving in the samedirection, and the right front andleft rear
`cylinders are always moving in the same direction. Over a given period oftime,all four
`cylinders are moving the same displacement (2 moving up x mm, and 2 moving down x
`mm). Since this does not require valve commandsto accomplish, the floating will occur
`in travel mode.
`It should also occur during milling when no commandsare being given
`(which isn’t very often).
`It does not matter if PTS is on oroff, because it only occurs
`when there is no flow from the valves.
`Reference data file GradeControl_1 (approx 300-500 sec). Thelater part of the data run
`showsthe machine being roaded over uneventerrain and the leg cylinder movement
`without valve command. See plot ‘Grade_Control_1 displ’ to see cylinder displacement
`values overseveral seconds (showshowall displacements are equal).
`Advantages — this system will function whether the valves or grade control are
`functioning or not.
`It does not rely on controls or reliability of components (other than
`hoses).
`
`
`
`Questions?
`Howdoes this interact with PTS?
`Doesit come into play during milling or only travel?
`It does not appear there is any control of the valves during travel if the grade controls are
`not on — is this correct?
