Specific embodiment
The present invention will be described in detail below with reference to the accompanying drawings: shown in Fig. 1-4, electro-hydraulic guide of the present invention adds ratio
The multi gear position reversing control system of example control, a kind of electrohydraulic control system of achievable multi gear position pavement construction machinery flexible shifting, it
Including electro-hydraulic gear control module 1, Prop-pressure control module 2,3 three parts of oil circuit distribution module composition, it is characterised in that institute
It states oil circuit and distributes 3 pieces of mould settings in bottom, be equipped with electro-hydraulic gear control module 1 and Prop-pressure control module 2 above, it is described
The left side of ratio pressure module 2 is arranged in electro-hydraulic gear control module 1, is equipped with gap between the two.
As shown in Figs. 1-3: the oil circuit distribution module 3 is the partition group by oil transportation plate and its upper and lower surface with gasket
At six oil circuits of total oil inlet, gear and the direction clutch and gear-box that are provided with control system on the oil transportation plate connect
Mouth A, B, C, D, E, F, wherein D, E, F are gear-box direction clutch interface, and A, B, C are gear clutch interface, and by interior
Oil circuit is respectively connected to 2 module of electro-hydraulic gear control module 1 and Prop-pressure control.
The Prop-pressure control module 2 is installed by electro-hydraulic proportional reducing valve 12,13,14 and proportioning valve as shown in Figure 1:
Valve body, sealing element composition, proportioning valve installation valve body and 12,13,14 arranged parallel of proportioning valve in the oil transportation direction plate D, E, F from
The top of clutch interface, and by interior oil communication, the proportioning valve is the decompression of a kind of plug-in, electrical-liquid control
Valve, when proportion electro-magnet electric current is zero, proportioning valve oil circuit is in close state.12,13,14 pairs of proportioning valve enter D, E, the side F
Secondary pressure adjusting is carried out to the working oil of clutch, meets the pressure versus time accelerated curve of oil liquid and is wanted without crash change of speed
It asks.
As shown in Figure 2: the electro-hydraulic gear control module is by reversing solenoid valve M1, M2, M3, M4, check valve 8,9, throttling
Valve 10,11, main pressure valve, pressure-control valve and two reversing slide valves 4,5,6,7 form, the reversing solenoid valve (M1, M2, M3,
M4 reversing slide valve (5,7,4,6)) are controlled respectively, the front end of two reversing slide valves is arranged in the pressure-control valve, passes through list
To valve (8,9), throttle valve (10) and reversing slide valve connection, described reversing solenoid valve M1, M2, M3, M4 are by receiving shift telecommunications
Number realize the switching of gear.
Working principle of the present invention is: after oil liquid is delivered to the P entrance of control system by working barrel, respectively enter M1, M2,
