The working principle of hydraulic transmission gearbox hydraulic system is as follows:
Oil pump provides power oil for hydraulic system.Main pressure regulator valve 211 control system pressure, pressure setting is 0.9 ~ 1.1MPa, and unnecessary hydraulic oil enters lubricating oil path flow through torque-converters 14, cooler 141 after main pressure regulator valve 211 overflow after.Torque-converters oil circuit 0.3 ~ 0.6MPa pressure is controlled by relief valve 212.
As shown in Figure 5, the hydraulic oil that oil pump 20 supplies clutch oil circuit flows through inching valve 213 after damping hole 218 throttling, gives trimmer valve 214 topping up simultaneously; When supercharging pressure (diagram A point pressure) reaches setting pressure, recuperation valve 216 just changes by the normally closed function of diagram energy of often starting shooting into.The hydraulic oil that oil pump 20 supplies clutch oil circuit simultaneously also can flow through through damping hole 217 filler opening (illustrating A point) that the fluid flowed out with inching valve 213 after recuperation valve 216 collaborates to shift valve 215.When current shift valve 215 is in meta, the filler opening of forward gear clutch 151 piston, retrogressing shelves clutch 131 piston is all connected with oil return circuit, and clutch is all in releasing state, and gearbox is neutral state.When shift valve 215 is in the position of left side function, A point oil circuit with retreat that shelves clutch plungers is connected, forward gear clutch piston and oil return circuit connect, retrogressing shelves clutch is in engagement, forward gear clutch is in releasing state, and gearbox is for retreating shelves engagements.When shift valve 215 is in the position of right side function, A point oil circuit and forward gear clutch piston are connected, retreat shelves clutch plunger and oil return circuit is connected.Forward gear clutch is in engagement, retrogressing shelves clutch is in releasing state, and gearbox is forward gears engagement.
The innovation of this hydraulic system is: when shift valve 215 is in the moment of commutation position, the hydraulic oil of A point is when shift valve 215 flows to forward gears (or retreating shelves) clutch and promotes clutch plunger motion, and the pressure of A point oil circuit can be down to below the commutation setup pressure value of recuperation valve 216 instantaneously.Therefore recuperation valve 216 just can return back to normally off in the spool function of this moment, thus has just cut off damping hole 217 supplements fuel feeding compensation oil circuit to A point oil circuit.Just the hydraulic shock of clutch engagement process can be alleviated, to improve the stationarity of forklift-walking starting stage by the damping increasing damping hole 218.Once (when A point pressure rises to more than setting value) recuperation valve 216 just automatically switches into normally open after vehicle gentle start, compensate oil circuit (damping hole 217 oil circuit) and just often open repairing.The internal leakage increase caused because of sealing wear to make up clutch oil circuit makes clutch pressure reduce the various harmful effects brought.
In the present embodiment, oil pump is crescent gear pump, and by motor by pump impeller Direct driver, oil pump provides pressure oil to system, after fluid after fluid torque converter work enters the radiator on vehicle, then enter the movement parts such as gearbox lubrication friction plate, bearing and gear.
