Description
Technical field
The present invention relates to a kind of hydraulic brake pressure servo valve, the brake load device of especially a kind of pressure servo valve.
Background technology
Currently, being fixed vessel as its vessel of brake disc device that pressure servo valve load uses, spring rate is general
Also it immobilizes, such device has as a drawback that：
1）It, can only be by replacing entire brake since vessel is fixed when needing to meet the load of different pressures servo valve
Disk device realizes, needs to redesign, processing part, causes development cost high, the process-cycle is long.
2）When needing to change spring rate, the spring of multiple sub- vessels need to be replaced simultaneously, is not easy to operate, workload
Greatly.
Invention content
The present invention is to provide for a kind of volume and the adjustable simulation vessel of rigidity, more in former brake disc device for replacing
A fixed vessel is solved due to different brake disc devices needed for different model pressure servo valve, and device vessel is again non-adjustable, replaces
The problems such as spring is inconvenient, the demand to solve different loads needed for different model pressure servo valve or different spring rates are asked
Topic.
To achieve the above object, the technical scheme is that：A kind of volume and the adjustable simulation vessel of rigidity, including cylinder
Cylinder, piston, spring, spring base, the cylinder barrel is interior equipped with piston, spring base, and spring base is connect by spring with piston, and spring
Seat is by cylinder pin connection cylinder barrel, and straight pin can be moved along the straight pin keyway on cylinder barrel, stretches out the spring base of cylinder barrel end cap
Upper threaded connection adjusting nut and locking nut, and unilateral thrust axis is housed between the step end face of adjusting nut and cylinder barrel end cap
It holds, the volume size of simulation vessel is adjusted by rotating adjusting nut.
The cylinder barrel end cap is equipped with the visual scale for showing vessel size.
The visual scale is fixedly connected by rear sight base with cylinder barrel end cap.
The beneficial effects of the invention are as follows：
1）Due to adjustable volume, when needing to simulate different size of load, can be adjusted by manual rotation's adjusting nut
Whole volume size, and volume size is visual by scale, no longer needs to redesign or process part, reduces development cost and add
The work period.
2）Due to adjustable volume device only one spring, only replaces a spring and change spring rate, reduce work
It measures, reduce operation difficulty.
3）Under the function of adjustable volume, due to the effect of straight pin, it is ensured that spring base does not occur to turn in adjustment process
It is dynamic, it only moves along a straight line, reduces the degree of wear of part, improve the service life of product.
The adjustable simulation vessel technology of volume/rigidity is applied in pressure servo valve brakes load device, it can be big generous
Just the research of the demand and its performance test of different model pressure servo valve.
The present invention uses in the pressure valve multi-function test stand equipment that Shanghai Hengtuo Hydraulic Pressure Control Technology Co., Ltd. develops
The adjustable simulation vessel technology of volume/rigidity, the load device for simulating airplane brake system achieve good effect
Fruit, the replacement workload brought due to reducing needed for the different types of pressure servo valve different brake gears.
Description of the drawings
Fig. 1 is the volume and the adjustable simulation holding cavity structure sectional view of rigidity of invention；
Fig. 2 is the vertical view of Fig. 1.
Specific implementation mode
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Such as Fig. 1, shown in 2, a kind of volume and the adjustable simulation vessel of rigidity, by cylinder barrel 1, piston 2, spring 3, spring base 4,
The compositions such as straight pin 5, adjusting nut 6, single thrust bearing 7.
Spring base 4 is connect by spring 3 with piston 2, is mounted in cylinder barrel 1, and spring base 4 then passes through cylinder with cylinder barrel 1
Pin 5 connects；1 rightmost side of cylinder barrel is equipped with adjusting nut 6, and 6 right end of adjusting nut is tightened by locking nut 8, while
The outside of adjusting nut 6 is equipped with single thrust bearing 7, and the axial movement of adjusting nut 6 is limited by unilateral bearing 7.Cylinder
It is machined with straight pin keyway on cylinder 1, limits the movement of 4 direction of rotation of spring base, therefore, under the constraint of straight pin 5, spring
Seat 4 is only capable of moving along a straight line in an axial direction relative to adjusting nut 6.The position of spring base 4 changes as a result, corresponding to hold
Product size is changed, and the volume size before and after adjustment can be read by 9 scale of visual scale.Volume and rigidity are adjustable
Simulation vessel technology is to change its volume size by adjusting the position of spring base 4.
When manual rotation's adjusting nut 6：On the one hand, spring base 4 is attached with adjusting nut 6 by screw thread, due to
The outside of adjusting nut 6 is equipped with single direction thrust ball bearing 7, under the constraint of single direction thrust ball bearing 7, adjusting nut 6 be only capable of into
Row rotary motion, at this point, being equivalent to spring base 4 can be moved relative to adjusting nut 6；On the other hand, spring base 4 and cylinder barrel
1 is attached by straight pin 5, and straight pin keyway is machined on cylinder barrel 1, limits the movement of 4 direction of rotation of spring base, because
This, under the constraint of straight pin 5, spring base 4 is only capable of moving along a straight line in an axial direction relative to adjusting nut 6.Spring base as a result,
4 position changes, and corresponding volume size is changed, and the volume size before and after adjustment can be read by scale label
Go out.
In addition, conventional brake load device is generally multiple vessels, each vessel is all made of the consistent spring of rigidity, because
This need to replace the spring of each vessel simultaneously when needing replacing spring rate, and present apparatus only one simulates vessel, accordingly
Ground will replace the spring that spring rate only needs to change the vessel, easy to operate, also greatly reduce workload.
