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 sound ratio of rigidity controlling device that is used for rail vehicle and automobile carrying liqs damping rubber joint specifically; This device changes the effect of rubber arthrosis assembly dynamic stiffness through at rubber arthrosis assembly set inside liquid container and adjustable passage to play.
Background technique
Rubber arthrosis is a kind of rubber absorber that is widely used in rail vehicle and automobile, in some cases, requires the quiet rigidity of rubber absorber little; Dynamic stiffness is big, and promptly the sound ratio of rigidity is big, and the pivoted arm node that uses with rail vehicle truck is example; When bogie moves in the straight line highway section,, require the pivoted arm node that big location dynamic stiffness can be provided in order to guarantee operation stability; And through bend the time,, require rubber arthrosis that little static stiffness is arranged again in order to guarantee the passing ability of bogie; But because the inherent characteristic of rubber material itself; The sound ratio of rigidity that rubber arthrosis can provide does not reach requirement, often need make system architecture become complicated by other component to reach usage requirement.
It is a kind of rubber absorber that is applied to rail vehicle and automobile that carrying liqs damping rubber joint is formed; Have the big characteristics of sound ratio of rigidity, but present product is after entrucking, its each item performance 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 under some specific situation, 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 the utility model is can not change under specific circumstances to existing carrying liqs damping rubber joint the deficiency of its dynamic rate, proposes a kind of adjustable carrying liqs damping rubber joint sound ratio of rigidity controlling device of sound stiffness variation that can make carrying liqs damping rubber joint.
The technology implementation scheme that purpose proposed according to model utility is: a kind of rubber arthrosis at set inside liquid container and adjustable passage comprises the rubber arthrosis overcoat, mandrel, elastic caoutchouc; Elastic caoutchouc is enclosed within on the mandrel; Its characteristics are: outside rubber arthrosis, be with a metal-coating, rubber arthrosis press-fits in metal-coating; Outside rubber arthrosis, put with the axis and be provided with plural independent liquid container for the symmetry axis symmetrical position; Each independent liquid container is interconnected through the throttling passage that is arranged on the mandrel; The throttling passage adjusting axle is located at the mandrel inside of rubber arthrosis; And the adjusting axle two ends are pressed with spring respectively, and spring at one end is circumscribed with an adjustable stops; Adjustable stops slides in the guide pad, and can be under external force along moving axially in the hole of guide pad; Guide pad is fixed in the tapped hole of the throttling passage end on the mandrel through screw thread.Seal with anti-leak through O-ring seals between the each several part.
The advantage of the utility model is: through 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
To combine accompanying drawing and embodiment that the utility model is done further to describe below.
Can find out that through accompanying drawing 1 the utility model relates to a kind of rubber arthrosis assembly at set inside liquid container and adjustable passage, comprises rubber arthrosis overcoat 36, mandrel 37, elastic caoutchouc 38; Elastic caoutchouc 38 is enclosed within on the mandrel 37; Its characteristics are: outside rubber arthrosis overcoat 38, be with a metal-coating 39, rubber arthrosis press-fits in metal-coating 39; On rubber arthrosis overcoat 36 with the axis for the symmetry axis symmetrical position is provided with plural independent liquid container 40, each independent liquid container 40 is interconnected through the throttling passage 41 that is arranged on the mandrel; Adjusting axle 42 is located at mandrel 37 inside of rubber arthrosis, and adjusting axle 42 two ends are pressed with spring 43 respectively, and spring at one end is circumscribed with an adjustable stops 44; Adjustable stops 44 slides in the guide pad 45, and can be under external force along moving axially in the hole of guide pad; Guide pad 45 is fixed in the tapped hole of throttling passage 41 ends on the mandrel through screw thread.Seal with anti-leak through O-ring seals between the each several part.
Accompanying drawing 2 is the side sectional view of accompanying drawing 1.
Accompanying drawing 3 is the concrete structure of rubber arthrosis, mainly comprises rubber arthrosis overcoat 36, mandrel 37, elastic caoutchouc 38; Elastic caoutchouc 38 is enclosed within on the mandrel 37; Two ends on the surface of rubber arthrosis overcoat 36 have 2 circular grooves 46 that are used to adorn O-ring seals; For the symmetry axis symmetrical position is provided with several liquid container 47, on mandrel 37, through perforate liquid container 47 is communicated with mandrel endoporus 48 with the axis, mandrel endoporus 48 is an axial step shape blind hole; There is screw thread 49 mandrel endoporus 48 ends, are used to assemble the guide pad of adjustable dog.Opening the liquid container position, having an annular sulculus 50, under the cooperation of metal-coating, forming an annular damp channel along the rubber arthrosis outer surface.
Accompanying drawing 4 is the concrete structure of embodiment's four adjusting axles, axle be shaped as little step-like in two broad in the middle, have O shape seal groove 51 in part broad in the middle, and be provided with oil groove 52.
Working principle:The rubber arthrosis assembly in the course of the work, overcoat and mandrel are done radially relative movement, the resisting medium in the liquid container of a side flows to the liquid container of the side that stretches by compression; In needs dynamic antivibration power, when promptly dynamic rate was big, mandrel endoporus 48 staggered with mistake oil groove 52; Resisting medium can't pass through from here, and its flow path can only be for through annular sulculus 50, and resisting medium produces dynamic antivibration power when flowing through annular sulculus 50; Do not needing dynamic antivibration power, i.e. dynamic rate hour, the throttling passage adjusting axle is under the effect of external force; Axially move; Make mandrel endoporus 48 and cross the oil groove 52 formation passage that aligns because mandrel endoporus 48 is enough big with the sectional area of crossing oil groove 52, resisting medium thus passage through not producing damping force.After external force disappeared, under the effect of spring, the dynamic adjustments axle was got back to initial position again, closed once more through mandrel endoporus 48 and the passage of crossing oil groove 52, realized the automatic adjusting of dynamic antivibration power thus.
