The output flow of thepump is proportional tothe pilot pressure.A separate pilot oilcircuit is necessary. From this, the controlpressure is reduced tothe desired set value bymeans of a suitablepressure control valve(with P-T line) andthrottle in P-line 0.8 Ø(0.03 in).

To work in bothdirections, a solenoidvalve is needed to switchthe pilot flow from A toB (pos. 30 in modelcoding, option “K”).The DP-control can beused for stepless flowcontrol with standardrequirements fordynamic and precision.

No feedback signal isneeded, an opticalindicator recommended (pos. 24 in modelcoding, option “V”).A pilot oil filter can bemounted in-line betweenpump and control (pos.42 in model coding,option “V” or “E”).Pressure limiter orpower limiter overridenot available (for suchand other options pleaserefer to PVW-Series).

The SP control operatesa hydrostatic drive andworks without throttlelosses within electricallyadjustable limits. This isdone by controllingdelivery flow withelectrical swashplateangle feedback(electrical closed-loopcontrol).

All control values arerecorded as an electricalsignal and lead back tothe control card. Theproportional valve andservo piston transformthe output signal of thecontrol card to thedesired setting.This results in a veryprecise and dynamiccontrol.

Application Data -FluidRecommendations

Case Flushing Requirements

A check valve must notbe used in the drainpipe. The drain pipe mustinterminate below the oillevel in the reservoir.For all other conditionswith low pressure <20bar (<300psi) and lowflow (<10% of Qmax)case flushing is required.For operation withspecial fluids HFB andHFC, case flushing isrecommended.

Flushing Flow

Flushing flow via thepump case should be>1% of maximum pumpflow. Maximum flushingflow depends on casepressure.

Notes:• All listed ratings are

based on the use of agood quality fluid.

• Alternative fluids havea reduced tolerance forcontamination overpetroleum-base fluids.Good filtration istherefore critical.

• The pumps will provideexceptional life whenused with a goodquality clean fluid atthe pump ratingsspecified for that fluid.

Fluids

Pumps in the catalog areprimarily designed tooperate withconventional petroleum-based hydraulic oil.Alternative fluids andrestrictions:• Fluid maintenance is

critical to the durabilityof all hydrauliccomponents, andparticularly so withhydraulic pumps. Thisbecomes even more ofa factor whenalternative fluids areused. All types ofalternative fluidsrequire extensivemaintenance in orderto maintain properlevels of watercontent, acidity,viscosity andcontamination.

Fluid Cleanliness

These pumps are ratedfor anti-wear petroleumfluids with acontamination level of18/15/13 per ISO 4406.Operation in fluids withhigher contaminationlevels than this is notrecommended and mayreduce the life of thepump components.Fluids other thanpetroleum, severe

service cycles, ortemperature extremesare cause for adjustmentof these codes. Pleasecontact your Eatonrepresentative for specialduty cyclerecommendations.Eaton pumps, as well asany variabledisplacement pistonpumps, will operate withapparent satisfaction influids up to the ratingspecified here.Experience has shown,however, that pump andhydraulic system life isnot optimized with highfluid contaminationlevels (high ISOcleanliness codes).Proper fluid condition isessential for long andsatisfactory life ofhydraulic componentsand systems. Hydraulicfluid must have thecorrect balance ofcleanliness, materials,and additives forprotection against wearof inclusion of air. Essential information onthe correct methods fortreating hydraulic fluid isincluded in Eatonpublication 561- "VickersGuide to SystemicContamination Control"-

available from your localEaton distributor.In this publication,filtration and cleanlinesslevels for extending thelife of axial piston pumpsand other systemcomponents are listed.Included is an excellentdiscussion of theselection of productsneeded to control fluidcondition.

Ordering Procedure

When ordering pleasespecify full modeldesignation of itemsrequired; see "ModelCodes" section of thiscatalog.Note the following:• Designation of variable

The schematic enclosedshows a typical heavy dutyhydrostatic transmission. Thepump and motor are themain components. The filter,reservoir, heat exchanger andoil lines make up the rest ofthe system.

The function of thesecomponents is describedbelow:

The Pump

The pump generates theflow of high pressure oil. Thetypical transmission employsa variable displacementpump. The variabledisplacement feature allows

the amount of oil pumped tobe varied. And the amount ofoil pumped controls themotor‘s output speed. Forexample, when the pump‘sdisplacement is zero, no oilis pumped and thetransmission‘s output shaftis at rest. Conversely,maximum displacementproduces maximum speed.The direction of highpressure flow can also bereversed; doing so reversesthe direction the output shaftrotates. An external energysource, called the primemover (usally an electricalmotor), turns the input shaftof the pump.

The Motor

The motor uses the highpressure oil flow from thepump to producetransmission output. Thehigh pressure oil comes tothe motor through one of thehigh pressure lines. lt entersthe motor, turns the outputshaft, then returns to thepump. The pump and motorin the drawing are connectedin a closed-loop circuit.

Important:

Remember, the pumpgenerates flow, and the loadon the motor‘s output shaftcauses resistance to thatflow. That resistance to flowis what creates the highpressure. Therefore, the oilflowing in the lines thatconnect the pump and motoris called ”high pressureflow.”

The pump and motor in thedrawing are contained inseparate housings. Thisconfiguration providesmaximum flexibility in designand transmission installation.

Description of ClosedLoop Transmission withElectric MotorDisplacement Control


ApplicationInformation(cont.)

The Charge Pump

The charge pump generatesa low pressure oil flow thathas three functions. First, itsupplies a continuous flow ofoil through the pump andmotor cases. This ”caseflow” keeps the transmissioncool. In the drawing, thecase flow goes from themotor to the pump, then tothe heat exchanger and backto the reservoir. Second, thecharge pump keeps the highpressure lines filled. Thisensures that thetransmission remains primedeven after extended periodsof running in neutral. Finally,charge pump flow providesback pressure in the highpressure lines when thetransmission is in forward orreverse. The charge pumpcontains a relief valve thathelps maintain the pressureof the low pressure oil flow.

The charge pump bolts ontothe pump and its input shaftconnects with the input shaftof the pump. The chargepump inlet receives oil fromthe reservoir.

The Valve Block

The valve block contains atwo-sided high pressurerelief valves, a shuttle valveand a charge pressure reliefvalve.The high pressure relief valveprotects the transmissionfrom pressures that are toohigh. The shuttle valve andcharge pressure relief valvedirect excess charge pumpflow into the pumps case.This case flow cools thepump. The valve block boltsdirectly to the pump.

The Heat Exchanger,Reservoir, Filter, and OilLines

The heat exchanger,reservoir, filter and oil linesare all necessary for heavyduty transmission operation.The heat exchanger connectsbetween the case flow outletand the reservoir. lt cools theoil before it enters thereservoir. The heat exchangermust be fitted with a by-passvalve that opens when casedrain pressure gets too high.The by-pass valve isespecially important duringcold starts when the oil isthick. The reservoir supplies asteady flow of oil to thecharge pump inlet. lt alsoprovides room for the oil toexpand as it gets hot and forentrapped air to escape. Thefilter is installed between thecharge pump outlet and thevalve block. lt removescontaminants from the oil.

The oil lines provide passageways for the oil flowingamong the transmissioncomponents. They must bestrong enough to withstandthe pressures generated andmay be rigid or flexible.

Description of Operation

A hydrostatic transmission isa dynamic system thatoperates through a widerange of conditions.Nevertheless, this wideoperating range canconveniently be divided intothree basic modes: neutral,forward and reverse.

The schematics and theiraccompanying explanationswill help you visualize what‘sgoing on inside thetransmission during each ofthe operating modes.

Important: As you study thefollowing flow descriptions,remember that in all modesof operation, the input shaftof the pump is being turnedby an external power source.

Neutral

The hydrostatic transmissionis in neutral when thevariable pump‘sdisplacement is zero. Withzero displacement, no highpressure oil is pumped to themotor and its output shaft isstopped.

Putting the control signal inthe neutral position centersthe swashplate. With theswashplate centered thepistons don‘t reciprocate asthe cylinder barrel is rotatedand no high pressure oil ispumped.

The charge pump, which isconnected to the input shaft,pumps oil in all modes oftransmission operation. Inneutral, it takes cooled,filtered oil from the reservoirand fills the system. Chargepump flow passes throughthe check valves in thepump’s end cover and fills thepump pistons, the highpressure lines and themotor‘s pistons. This oil flowis intended to make up forinternal leakage and keep thecircuit primed.

After the high pressurecircuit has been primed, thecharge pump pressure opensthe charge pressure reliefvalve located in the chargepump. This directs the chargepump flow through the pumpcase and back to thereservoir. This oil flowflushes and cools the pump.

The forward mode and thereverse mode are similar, sothey will be grouped andcalled the forward! reversemode.


ApplicationInformation(cont.)

Forward/Reverse

The hydrostatic transmissionis in the forward/reversemode when flow in the highpressure circuit causes themotor shaft to rotate.

Flow in the high pressurecircuit is created by tiltingthe pump‘s variableswashplate from its center orneutral, position. With theswashplate tilted, the pistonsreciprocate as the cylinderbarrel rotates and flow isgenerated.

The swashplate may be tiltedto either side of center.Tilting it one way generatesflow that makes thetransmission go forward.And tilting it the other wayreverses flow and the motorshaft rotates in the oppositedirection.

Besides controlling direction,the swashplate angle alsocontrols output speed.Swashplate angle affectsspeed by changing thepump‘s displacement. The

largest swashplate angleproduces the largestdisplacement and the fastestmotor speed.

The Electrical MotorDisplacement Control circuitvaries the swashplate angleby turning a spindle directlyfixed to the servo piston.According to the direction ofrotation of the control motor,the spindle turns and theswashplate is tilt until themotor is switched off (formore detailed explanationsrefer to separate descriptionof the Electrical MotorDisplacement Control).

Charge pump flow that is notused by the control circuitpasses through the endcover check valve into thebw pressure side of the loop.There it provides backpressure to the motorpistons.

The spring centered shuttlevalve, located in the pump‘svalve block, moves to connectthe low pressure side of theloop to the charge pressure

relief valve. When backpressure gets high enoughthe charge pressure reliefvalve, in the valve block,opens and charge pump flowenters the the pump case.

Case flow flushes the pumpcases and helps keep thetransmission cool. Thecharge pressure relief valvetypically has a lower settingthan the charge pressurerelief valve in the chargepump. This is so case flowwill begin at the motor, go tothe pump, and return to thereservoir.

The charge pressure reliefvalve in the charge pumpopens when thetransmission is in neutral andthe shuttle valve is centered.

The 2-side high pressurerelief valve opens to connectthe high pressure side of theloop to the low pressure sideif the motor stalls and thepressure gets too high. Thisvalve works in forward and inreverse direction.

Last remark

All valves, relief valves andswitches, are adjusted at thetest bench accordingcustomers specification andneeds and must not bemisplaced without specialknowlegde of the hydraulicsystem!
