Specific embodiment
As shown in Figure 1, multifunction integrated valve includes main valve body 12, throttling passage switching valve is successively arranged inside main valve body 12
Body 5, overflow valve body 6 and overflow valve spring retainer 10, the interior throttling passage that is equipped with of throttling passage switching valve 5 switch spool 3, overflow
It flows and is equipped with relief valve spool 6 in valve body 7, be equipped with overflow valve spring 11 in overflow valve spring retainer 10.It is equipped with outside main valve body 12
Throttle valve body 13, is successively arranged throttle valve spring seat 16, throttle valve spring 15 and throttle valve core 14 in the valve body 13 that throttles,
15 sets of throttle valve spring on the boss of throttle valve spring seat 16 and throttle valve core 14.Throttling passage switches spool 3, overflow valve
Spool 6 and 11 three of overflow valve spring are coaxial, and it is axial that throttle valve core 14 is axially parallel to relief valve spool 6.On main valve body 12
There are P mouth 19 and T mouth 20, there is two accesses, respectively throttling route 17, relief line 18 between P mouth 19 and T mouth 20.Overflow valve
It is equipped with top cover 9, heading 8 and stopper, top cover 9 between spring 11 and relief valve spool 6 to be connected on overflow valve spring 11, blocks
Stop member is fixed on relief valve spool 6, and heading 8 is between stopper and top cover 9.5 bottom surface of throttling passage switching valve has recessed
Slot is equipped with ratio magnet 1 and armature lifter 2, armature lifter 2 is for pushing throttling for cooperating convex solenoid valve in solenoid valve
Channel switches spool 3.
When the power-off of proportion electro-magnet 1 does not work, armature lifter 2 is retracted to the left, and it is logical in throttling that throttling passage switches spool 3
Road switching valve core spring 4 is retracted to the left under acting on, and throttling route 17 is connected to, and oil liquid flows to T mouthfuls through throttling path line 17 from P mouth 19
20.Pressure is generated by the throttling action of throttle valve at this time, choke pressure size depends on the restriction coefficient and oil liquid of throttle valve
Uninterrupted.
When proportion electro-magnet 1 powers off, electromagnetic force zero, overflow valve is maximum oil pressure relief, it is used as and is equivalent to peace at this time
Full valve.When external disturbance is excessive causes choke pressure excessive, part oil liquid guarantees system non-overloading by overflow valve overflow.
When proportion electro-magnet 1 works on power, armature lifter 2 stretches out to the right, and throttling passage switching spool 3 is pushed to transport to the right
Dynamic, throttling route 17 is closed, and 1 electromagnetic force of proportion electro-magnet switches spool 3 by throttling passage and acts on overflow valve valve to the right
The oil liquid pressure of core 6, P mouth 19 also acts on to the right on relief valve spool 6, overflow valve spring 11 by top cover 9 and heading 8 to
A left side acts on relief valve spool 6.When electromagnetic force and oil liquid pressure are greater than overflow valve spring 11 to the resultant force of relief valve spool 6
Active force when, relief line 18 is opened, and oil liquid flows to T mouth 20 by overflow route 18.Oil liquid oil pressure relief size and electricity
Magnetic force size is inversely proportional, and electromagnetic force is bigger, and oil liquid oil pressure relief is smaller.That is, oil pressure relief size can pass through ratio electricity
1 signal magnitude of magnet is controlled, and damper can change according to vehicle driving-cycle actively adjusts damping force size.
As shown in Fig. 2, can build active suspension system using the multifunction integrated valve, which includes hydraulic cylinder and pressure
Power fuel tank is connected with check valve 3, multifunction integrated valve, is made of pump, motor and check valve 1 between hydraulic cylinder and pressure oil tank
Executing agency, the valve arrangement that is made of high-speed switch valve 1 and high-speed switch valve 2.Wherein the piston inside hydraulic cylinder is with single
To valve 2.Multifunction integrated valve P mouth 19 is connected to hydraulic cylinder, and T mouth 20 is connected to pressure oil tank.
The system its can work in Three models according to vehicle Real-road Driving Cycle: Passive Mode, half aggressive mode and complete
Aggressive mode.
Under Passive Mode, solenoid valve, high-speed switch valve, motor and pump on multifunction integrated valve are in power-off and do not work
State, actuator generate damping force simply by the throttling action of the throttle valve on multifunction integrated valve, and the size of damping force takes
Certainly in the restriction characteristic of vibration velocity size and throttle valve, the direction of damping force is opposite with direction of vibration.
Under half aggressive mode, solenoid valve and high-speed switch valve on multifunction integrated valve work on power, multifunction integrated valve
On throttle valve shielded, motor and hydraulic pump power-off be not involved in work.Actuator is by solenoid valve control oil pressure relief, i.e., main
The size of dynamic control damping force, passes through the load of high-speed switch valve active control damping force and off-load.
Under full aggressive mode, throttle valve is in by masked state, other than solenoid valve and high-speed switch valve work on power, electricity
Machine and pump also work on power, and constant oil liquid flow is inputted to hydraulic cylinder rod chamber.Damping force size passes through solenoid valve control, resistance
Buddhist nun's power direction is by Speed On-off Valve, due to the constant flow rate that hydraulic pump provides, make system to the control of damping force more
It is smooth and smooth, so as to so that effectiveness in vibration suppression more preferably.
Technical principle of the utility model has been described above with reference to specific embodiments, these descriptions are intended merely to explain this reality
With novel technical principle, and it cannot be construed to the limitation to scope of protection of the utility model in any way.It is explained based on this,
Those skilled in the art do not need to pay for creative labor other specific embodiment parties that can associate the utility model
Formula all will fall within the protection scope of the utility model.
