Description
Technical field
The present invention relates to the hydrovalve technical field, be specifically related to a kind of hydraulic pressure installation that the fan liquid_viscosity regulator is controlled.
Background technique
In special vehicle uses, more than 80 ℃, do not allow engine misses when water temperature, prevent motor after stopping working, due to the situation of violent temperature shock generation engine scuffing.At present; it is that Normally closed type PWM direct proportaion reduction valve is controlled separately manipulation (PWM is pulsewidth modulation) that the fan liquid_viscosity regulator of controlling water temperature is controlled what adopt; it is the hydraulic pressure installation that prior art has only adopted a direct proportaion valve; the outage of direct proportaion valve is the state of shutting when automatically controlled inefficacy; sealed the fluid passage that leads to liquid_viscosity regulator mechanism; cause and to handle control, cause that under high temperature, fan can't rotate, thereby can't realize its cooling and purpose of shutting down rapidly.Run into this urgency vehicle and can only take the nature cooling method, the stand-by period is very long, and excessive fuel consumption is time-consuming, and the most important is the special occasions in special vehicle work, and wait just means is destroyed.
Summary of the invention
The invention provides a kind of hydraulic pressure installation that the fan liquid_viscosity regulator is controlled; solved when automatically controlled lost efficacy can't the drive fan rotation problem; when guaranteeing vehicle startup, the fluid of the sticking clutch of fan liquid is supplied with; and utilize the main pressure that reduction valve will be higher to be kept to the suitable manipulation oil pressure that fan liquid glues Clutch Control; realize controlling the continuation operation of fan, the target call that when satisfying automatically controlled the inefficacy, vehicle is in time shut down.
Technological scheme of the present invention is that a kind of hydraulic pressure installation that the fan liquid_viscosity regulator is controlled comprises inverse proportion valve, reduction valve and valve body; Reduction valve and inverse proportion valve respectively with valve body on valve opening fixed installation, reduction valve and inverse proportion valve on oil circuit for being connected in series, the oil outlet that is reduction valve is communicated with the filler opening of inverse proportion valve, the filler opening of reduction valve is communicated with main pressure fixing valve oil outlet in the system of vehicle transmission hydraulic system, the oil outlet of inverse proportion valve is communicated with the oil cylinder of the sticking clutch operation of fan liquid, and the drain tap of reduction valve all is communicated with the with no pressure opening oil tank with the drain tap of inverse proportion valve.
The invention has the beneficial effects as follows 1) the present invention arranges the reliability of the oil cylinder piston of the sticking clutch of reduction valve protection liquid, and when preventing automatically controlled inefficacys, the excessive possibility that causes the blade damage of the instantaneous rotation acceleration of moment fan of engine start; 2) after employing hydraulic pressure installation of the present invention, liquid glues the clutch fan control, especially when automatically controlled inefficacy, can guarantee the continuation rotation of fan, with parking checking trouble shooting fast, also can guarantee simultaneously automatically controlled control function when effective, than prior-art devices ensure on engine performance good.

Embodiment
As shown in Figure 2, the hydraulic pressure installation that the fan liquid_viscosity regulator is controlled of the present invention comprises inverse proportion valve 4, reduction valve 5 and valve body 6.The relation of inverse proportion valve 4 electric currents and oil pressure is, when electric current is increasing, and a kind of valve that corresponding oil pressure can be more and more less.Valve body 6 is carriers of reduction valve 5, inverse proportion valve 4 and embedded sensor 7, reduction valve 5, inverse proportion valve 4 and embedded sensor 7 are in the same place by valve body 6 integrated combinations, be that reduction valve 5 and inverse proportion valve 4 are installed by the valve opening separately of processing on valve body 6 respectively, whole integrated valve group is fixed by 6 bolts and transmission case body.For being connected in series, namely the oil outlet 10 of reduction valve 5 is communicated with the filler opening 14 of inverse proportion valve 4 on oil circuit for reduction valve 5 and inverse proportion valve 4, and the filler opening 9 of reduction valve 5 is communicated with main pressure fixing valve oil outlet in the system of vehicle transmission hydraulic system.The oil outlet 15 of inverse proportion valve 4 is communicated with the oil cylinder of the sticking clutch operation of fan liquid, and the drain tap 8 of reduction valve 5 all is communicated with the with no pressure opening oil tank with the drain tap 13 of inverse proportion valve 4.The oil pressure one tunnel of embedded sensor test is the entrance oil pressure of inverse proportion valve 4, and namely the outlet oil pressure of reduction valve 5 is the oil pressure of hydraulic fluid port 12, and another road is the outlet oil pressure of inverse proportion valve 4, i.e. the oil pressure of hydraulic fluid port 16.Embedded sensor 7 is fixedly connected with valve body 6 by 4 bolts.Embedded sensor 7 carries out Real-Time Monitoring and the collection of two-way pressure, provides convenience for fixing a breakdown or provides the feedback oil pressure for the control of fan speed-regulating valve.
Working procedure of the present invention is, hydraulic oil in the system of vehicle transmission hydraulic system enters from the filler opening 9 of reduction valve 5, this road binders presses the manipulation oil pressure that needs with respect to liquid_viscosity regulator mechanism slightly high, but adjust to suitable oil pressure by reduction valve 5, it is the manipulation low pressure oil pressure that liquid_viscosity regulator mechanism needs, this low-pressure hydraulic oil enters the filler opening 14 of inverse proportion valve 4 afterwards, can realize like this oil circuit series relationship of reduction valve 5 and inverse proportion valve 4 in hydraulic schematic diagram.Fluid is supplied with the oil cylinder of the sticking clutch operations of fan liquid through oil outlet 15 outputs after the filler opening 14 of inverse proportion valve 4 is by automatically controlled control to inverse proportion valve.When automatically controlled inefficacy, inverse proportion valve 4 is off-position, and the inverse proportion valve spool is standard-sized sheet, and fluid directly reduces by reduction valve and namely enters liquid_viscosity regulator mechanism after main pressure.
Except above-mentioned said composition structural type, the Placement that other can also be arranged, so long as comprised these two of reduction valve and inverse proportion valves must parts and reduction valve and inverse proportion valve (reduction valve is front for series relationship on oil circuit, inverse proportion valve is rear) and any structural type of composition, no matter and the pressure occasion of using, temperature occasion are how, and be all relevant with this patent summary of the invention.For example: valve body can not be integrative-structure, can reduction valve and inverse proportion valve be exactly separately an integral body, oil circuit therebetween realizes by forms such as oil pipes, the collection of pressure can be to realize by the sensor of general sensor or other arbitrary forms.The material of valve body can be any one, but considers the requirement of loss of weight, can adopt for example aluminum metal of the slightly light material of material.
