Abstract
The utility model discloses a force protection device used under the high-low temperature environment. A cylinder is mounted at one end of a rocker; the other end of the rocker is connected to a fulcrum; a piston in the cylinder is connected to an actuating end; the cylinder is also connected to an energy accumulator; and a compressed air inlet of the cylinder is connected to a pressure-relief valve. The force protection device can endure temperature in large range, and the protection force does not change with the displacement.
Description
Technical field
The utility model relates to a kind of auto parts and components, is specifically related to a kind of protection unit of trying hard to keep.
Background technology
At present, automobile requires under different climatic conditions, to reach life-span of promise with parts, and is therefore antenatal with formal batch in freeze design usually, needs through harsh humid test and endurancing.To use efp to be example on the automobile, about 2,000,000 times endurancing is carried out in a very important endurancing (-40 ℃～85 ℃ usually) exactly under high and low temperature environment.Pedal applied force in process of the test is controlled at tolerance zone at needs, in case surpass, will damage product, can't judge because the life-span deficiency still is the artificial serious consequence of damaging causing, and can cause the delay of car load listing, causes heavy losses.Therefore, when the design endurance test bed, need solve this problem at the integrated extra protection unit of trying hard to keep.
How to design a kind of structure, the power above when product is done thermocycling, guaranteeing to apply is no more than the value of qualification.
There are three kinds of schemes present stage, and the problem of existence is distinguished as follows:
1. use spring structure.Existing problems: protection need be regulated inconvenience through pretightning force; In addition, protection is along with the increase of displacement can increase, and is not linear.
2. use air spring.Existing problems: temperature resistant grade can't meet the demands.
3. use the force transducer FEEDBACK CONTROL.Existing problems: in the life-span short (less than 2,000,000 times), need often to change.
The utility model content
The utility model technical matters to be solved provides a kind of protection unit of trying hard to keep that under high and low temperature environment, uses, and it can bear bigger temperature range, and protection does not change with change in displacement.
In order to solve above technical matters, the utility model provides a kind of protection unit of trying hard to keep that under high and low temperature environment, uses, and has cylinder to be installed in rocking bar one end, and the rocking bar other end is connected to fulcrum; There is piston to be connected to actuating station in the cylinder; Cylinder also is connected to accumulator; Place, cylinder compressed air inlet inserts reduction valve.
The beneficial effect of the utility model is: can bear bigger temperature range, protection does not change with change in displacement.
The ratio of its volume of said accumulator and cylinder internal volume was greater than 10: 1.
The seal of said cylinder is silicon rubber or teflon seal ring.
Said reduction valve is an adjustable pressure-reducing valve.
Cylinder is connected to accumulator and reduction valve through gas piping.
Said piston is connected to gas pedal actuating station.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Fig. 1 is the synoptic diagram of the said structure of the utility model embodiment.
Embodiment
The described protection unit of trying hard to keep that under high and low temperature environment, uses of the utility model has cylinder 6 to be installed in rocking bar 2 one ends, and rocking bar 2 other ends are connected to fulcrum 1; There is piston 11 to be connected to actuating station 4 in the cylinder 6; Cylinder 6 also is connected to accumulator 7; 10 places, cylinder 6 compressed air inlets insert reduction valve 8.Rocking bar 2 is motor-driven by other, and cylinder 6 theres connect actuating station, constitute the protection unit of trying hard to keep.
The ratio of said accumulator 7 its volumes and cylinder 6 internal volumes was greater than 10: 1.
The seal of said cylinder 6 is silicon rubber or teflon seal ring 5.
Said reduction valve 8 is an adjustable pressure-reducing valve.
Cylinder 6 is connected to accumulator 7 and reduction valve 8 through gas piping 9.
Said cylinder 6 inner carriers 11 are connected to gas pedal 3 actuating stations 4.
During installation, cylinder 6 is assembled on the rocking bar 2, actuating station 4 is installed on piston 11 simultaneously;
Cylinder 6 usefulness heatproof joints are connected with gas piping 9;
10 places insert accurate reduction valve 8, control system pressure in the compressed air inlet;
In pipeline and the United Nations General Assembly's volume accumulator 7, the ratio of its volume and cylinder internal volume was greater than 10: 1;
2 swings of piston 11 drive rocker, compression pedal 3 makes an experiment, and the power that end effector is applied on the pedal 3 can be greater than preset value, and preset value is regulated through regulating system air pressure.
The utility model is selected duplex cylinder 6 for use, and cylinder 6 is taken apart.The seal of cylinder 6 is the sealing ring 5 of silicon rubber or teflon.Bigger accumulator 7 is installed in gas piping 9 in addition, is guaranteed cylinder 6 in motion process, bigger variation does not take place in air pressure, keeps constant relatively protection.At last, cylinder 6 connecting lines and joint are selected the strong-willed pipe of heatproof for use.
Preferably, the said device of the utility model can be used for the long duration test of pedal 3, and other high low-temperature working structure of protecting of need trying hard to keep down is also applicable.
The said device of the utility model can bear bigger temperature range, and protection does not change with change in displacement.
The utility model is not limited to the embodiment that preceding text are discussed.More than the description of embodiment is intended in order to describe and explain the technical scheme that the utility model relates to.Conspicuous conversion or the alternative protection domain that also should be considered to fall into the utility model based on the utility model enlightenment.Above embodiment is used for disclosing the best implementation method of the utility model, so that those of ordinary skill in the art can use numerous embodiments of the utility model and the purpose that multiple alternative reaches the utility model.
