Description
Technical field
The utility model relates to the property regulation device of the rubber absorber of a kind of rail vehicle and automobile, is a kind of springrate ratio controlling device for rail vehicle and automobile belt liquid damping rubber arthrosis specifically; This device changes the effect of rubber arthrosis assembly dynamic stiffness by in rubber arthrosis assembly inside liquid container and adjustable passage being set to play.
Background technique
Rubber arthrosis is a kind of rubber absorber that is widely used in rail vehicle and automobile, in some cases, require the quiet rigidity of rubber absorber little, dynamic stiffness is large, be that springrate ratio is large, the pivoted arm node of using take rail vehicle truck is as example, when bogie moves in the straight line highway section, in order to guarantee operation stability, require the pivoted arm node that large location dynamic stiffness can be provided, and by bend the time, in order to guarantee the passing ability of bogie, require again rubber arthrosis that little static stiffness is arranged, but because the inherent characteristic of rubber material itself, the springrate ratio that rubber arthrosis can provide does not reach requirement, often need to be by other component to reach usage requirement, so that the system architecture complicated.
It is a kind of rubber absorber that is applied to rail vehicle and automobile that carrying liqs damping rubber joint forms, have the large characteristics of springrate ratio, but present product is after entrucking, its properties is fixing, dynamic stiffness is to change along with the variation of running environment in running, and in actual moving process, by situation under require rubber arthrosis to form in some specific situations, will to reduce its dynamic rate, this point is not accomplished in existing carrying liqs damping rubber joint.
Therefore in order to satisfy the needs of rail vehicle and automobilism, being necessary to develop a kind of sound rigidity can regulate as required, to reach the carrying liqs damping rubber joint of rail vehicle and automobile usage requirement.
The model utility content
The purpose of this utility model is can not change under specific circumstances for existing carrying liqs damping rubber joint the deficiency of its dynamic rate, proposes a kind of adjustable carrying liqs damping rubber joint springrate ratio controlling device of sound stiffness variation that can make carrying liqs damping rubber joint.
The implementer's case that proposes according to the purpose of model utility is: a kind of rubber arthrosis that liquid container and adjustable passage are set in inside comprises the rubber arthrosis overcoat, mandrel, elastic caoutchouc; Elastic caoutchouc is enclosed within on the mandrel; Its characteristics are: at the rubber arthrosis overcoat one metal-coating is arranged, rubber arthrosis press-fits in metal-coating; Outside rubber arthrosis, put take axis as the symmetry axis symmetrical position is provided with plural independent liquid container, each independent liquid container is interconnected by the throttling passage that is arranged on the mandrel, the throttling passage adjusting axle is located at the mandrel inside of rubber arthrosis, and is fixed by Cock screw; Seal with anti-leak by O-ring seals between the each several part.
The utility model has the advantage of: by the liquid damping device that can regulate is set in rubber arthrosis, the inside rigidity of rubber arthrosis is adjusted, realized that the rubber arthrosis dynamic stiffness is adjustable, can satisfy the service condition of vehicle fully, and simple in structure, easy to adjust, realize easily.

Embodiment
The utility model will be further described below in conjunction with accompanying drawing and embodiment.
Can find out that by accompanying drawing the utility model relates to a kind of rubber arthrosis that liquid container and adjustable passage are set in inside, comprises rubber arthrosis overcoat 1, mandrel 2, elastic caoutchouc 3; Elastic caoutchouc 3 is enclosed within on the mandrel 2; Its characteristics are: at rubber arthrosis overcoat 1 overcoat one metal-coating 4 is arranged, rubber arthrosis press-fits in metal-coating; On rubber arthrosis overcoat 1 take axis as the symmetry axis symmetrical position is provided with plural independent liquid container 5, each independent liquid container 5 is interconnected by the throttling passage 6 that is arranged on the mandrel, throttling passage adjusting axle 7 is located at mandrel 2 inside of rubber arthrosis, and fixing by Cock screw 8; Seal with anti-leak by O-ring seals 9 between the each several part.The concrete structure of metal-coating 4 is simple cylindricality tubular, and section press-fits rubber arthrosis within it.
Accompanying drawing 2 is the concrete structure of rubber arthrosis, mainly comprises rubber arthrosis overcoat 1, mandrel 2, elastic caoutchouc 3, has 2 circular grooves 10 that are used for the dress O-ring seals at the two ends on the surface of rubber arthrosis overcoat 1; On rubber arthrosis overcoat 1, be provided with two with last independent liquid container 5 take axis as the symmetry axis symmetrical position, being provided with throttling passage 6 at mandrel 2 is communicated with independent liquid container 5 each other, throttling passage 6 communicates with mandrel endoporus 11 simultaneously, mandrel endoporus 11 is axial step shape blind hole, hole step 12 is positioned at mandrel endoporus 11 and throttling passage 6 intersections, mandrel endoporus 11 port part have screw thread 14, be used for assembling throttling passage adjusting axle 7,14 places radially have set screw hole 15 at screw thread, are used for installing Cock screw 8.
Accompanying drawing 3 is the concrete structure of throttling passage adjusting axle 7, being shaped as of adjusting axle 7 is step-like, the each several part diameter is identical with corresponding mandrel endoporus 11, its pillow block rank 16 cooperate with the hole step 12 of mandrel endoporus 11, form throttling passage, circular groove 17 is used for the dress O-ring seals, and outside thread 19 cooperates with the internal thread 14 of endoporus.
Accompanying drawing 4 throttling passages form principle, the ring-shaped throttling passage is by the internal surface 20 at hole step 12 places of mandrel endoporus 11, the outer surface 22 at 16 places, pillow block rank of hole end surface 21 and adjusting axle 7, axial end 23 cooperates the annular pass 53 that forms rectangular cross-sections, and the size in this throttling passage cross section is along with adjusting axle 7 axial move left and right and changing in the hole.
Working principle:The rubber arthrosis assembly in the course of the work, overcoat and mandrel are done radially relative movement, see shown in the accompanying drawing 1, resisting medium in the liquid container of a side flows to the liquid container of the side that stretches by compression, its flow path is that independent liquid container 5 flows into lower independent liquid container 24 through throttling passage 6, when resisting medium is flowed through the upper part of throttling passage 6 and lower part 18, because the hole is enough large, do not produce effective damping force, damping force mainly produces when flowing through throttling passage 25, and the large I of damping force is regulated by the size of adjusting joint circulation road 25.For the product that makes same model is fit to different operating modes, the large I of throttling passage 25 under the screw-thread fit effect, axially moves adjusting axle 7, thereby obtains the throttling passage sectional area of required damping force by swivel circulation road adjusting axle 7.
