Description
Technical field
The utility model relates to a kind of hydraudynamic drive box assembly, specifically a kind of hydraulic transmission gear box solenoid electric valve composition.
Background technique
Solenoid valve belongs to the element of control loop break-make, and when the coil is energized, electromagnetic coil produces electromagnetic force, valve open, and during power-off, coil electromagnetism power disappears, valve closing.
Solenoid valve is two-position three-way valve, and when energized, P mouth is communicated with A mouth, and when power is off, A and T mouth is communicated with.Existing solenoid valve is generally provided with sealing at end face hydraulic fluid port and valve inner, and during high temperature media, sealing was easily lost efficacy, and high temperature makes spool and valve rod expand, if spool and valve body gap less, easily there is the phenomenon that solenoid valve is stuck.
Existing transmission case is all that air-operated solenoid valve controls, and namely utilizes pressurized air as medium to control main control valve action, and then controls gearshift, the commutation of locomotive.Compare with hydraulic control system, pneumatic control system action is steady not, and reliably, bearing capacity is low, and running precision is low, affects comparatively large, and have larger exhaust noise by load variations.
Model utility content
The utility model is steady not, reliable for pneumatic control system action set forth above, bearing capacity is low, the problems such as exhaust noise is large, and a kind of hydraulic transmission gear box solenoid electric valve composition of research and design.The technological means that the utility model adopts is as follows:
A kind of hydraulic transmission gear box solenoid electric valve composition, comprise electromagnetism valve bonnet, solenoid valve I, solenoid valve II, solenoid valve III, solenoid valve IV and electromagnetism valve plate, the sealing of electromagnetism valve bonnet is fixed on electromagnetism valve plate, four described solenoid valves are positioned at electromagnetism valve bonnet and are fixed on electromagnetism valve plate, described electromagnetism valve plate is provided with oil duct I, oil duct II, oil duct III, oil duct IV and oil duct V, described oil duct V is connected with the filler opening of four solenoid valves respectively by oil groove, described solenoid valve I, solenoid valve II, the working hole of solenoid valve III and solenoid valve IV respectively with oil duct I, oil duct II, oil duct III is communicated with random order with oil duct IV.
Further, the downside of described electromagnetism valve bonnet is provided with fuel outlet, is provided with screw thread in described fuel outlet, and is fixed with the plug screw and bonded washer that match with it.
Further, described solenoid valve I, solenoid valve II, solenoid valve III and solenoid valve IV are normal close type two-bit triplet formula guiding valve.
Further, described solenoid valve I and solenoid valve II common valve block I, described solenoid valve III and solenoid valve IV common valve block II, described electromagnetism valve plate is provided with spill port.
Further, described valve block I is located at the top of valve block II, and described spill port is located at the top of valve block II.
Further, described valve block I and valve block II are equipped with radiation hole.
Compared with the prior art, a kind of hydraulic transmission gear box solenoid electric valve composition described in the utility model has the following advantages:
1, compact structure, system solenoid valve used is guiding valve, requires less, thus Electrical heads small volume to electromagnetic force, and two solenoid valves share valve blocks, save space;
2, good thermal diffusivity, two solenoid valves controlling torque-converters and coupler oil-feed share a valve block, be positioned at the bottom of composition, the position of spill port is higher than the top of valve block, these two valves are often immersed in oil, the heat produced when the fluid of flowing can take away the work of valve block, and radiation hole is left in the position that valve block is installing coil, the electromagnetism valve bonnet of aluminum, these measures can ensure the thermal diffusivity that system is good;
3, due to the spool of solenoid valve and the Oil sealing length of valve body shorter, so work time certainly exist in let out, the oil of leakage directly can enter fuel tank through spill port, valve itself is sealing not, avoid oil temperature too high, the problem that sealing was easily lost efficacy, improve the working life of valve simultaneously;
4, the spool of solenoid valve and the gap of valve body exceed the gap of general valve, can adapt to the expansion of spool that transmission case causes because oil temperature is higher and valve rod, avoid the phenomenon occurring that valve is stuck.
