Description
Technical field
The present invention relates to the pivoted arm nodes that rail vehicle one is positioning device, more particularly, to a kind of variation rigidity pivoted arm node
And one be positioning device.
Background technique
Existing railway vehicle bogie primary positioning uses swing arm type positioning structure, and pivoted arm node is to determine rigidity, i.e., just
Angle value cannot change.But when actual vehicle is run, high stability needs high longitudinal rigidity, and good curving performance needs
Low longitudinal rigidity develops a kind of novel pivoted arm node to solve this contradiction, realizes that pivoted arm connection stiffness value can
Become, is required with adapting to straight path and the different of curve circuit, improve dynamics of vehicle performance.
Summary of the invention
The object of the present invention is to provide the pivoted arm nodes that a kind of rigidity value can be changed, to improve rail vehicle high stability and song
Line passage capacity, adapts to straight path and the different of curve circuit require.
To achieve the above object, the present invention provides a kind of variation rigidity pivoted arm node, it is characterised in that: including housing, main spring,
Auxiliary spring, mandrel, mandrel surface wind oil liquid pipeline, and main spring vulcanizes integral, the gold of main spring by rubber and metalwork two parts
Belong to part part to be press fit together with mandrel, the both ends of main spring are pressed with auxiliary spring, and auxiliary spring is also corresponding with main spring by rubber
Glue and the vulcanization of metalwork two parts are integral, and main spring and auxiliary spring periphery are pressed with housing, using mandrel as symmetry axis, in housing and
Two oil pockets are set between main spring, two oil pockets are communicated with the two-port of corresponding oil liquid pipeline respectively.
The main spring metalwork inner periphery is provided with semicircle helicla flute, mandrel excircle and main spring metalwork inner periphery upper half
Circle helicla flute is corresponding to be also provided with semicircle helicla flute, and oil liquid pipeline is placed in the helical cavity that two semicircle helicla flute engagements are constituted.
The oil pocket left cross sectional is the variation of big-small-big-small sequence from top to bottom, right side oil pocket cross section on to
Change the size to adapt to the damping force of different line requirements for small-big-small-big sequence down.
One kind one is positioning device, including pivoted arm node, it is characterised in that: pivoted arm node is described in above-mentioned any one
Pivoted arm node.
Oil liquid pipeline is arranged in the present invention between mandrel and main spring, and oil pocket, oil pocket and oil are equipped between main spring and housing
Liquid pipe road communicates, and in the process of running, in spring stress deformation, compression chamber, oil liquid flows vehicle in the duct, generates resistance
Buddhist nun's power, achievees the purpose that variation rigidity, and one containing the pivoted arm node is that positioning device can preferably adapt to straight path and song
The different of line route require, and improve dynamics of vehicle performance.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the longitudinal sectional view of Fig. 1；
It is positioning device schematic diagram that Fig. 3, which is using of the invention one,.
Specific embodiment
- Fig. 2 referring to Fig.1, the specific embodiment of the invention include housing 1, main spring, auxiliary spring, mandrel 6, and main spring is by rubber 2
Integral with the vulcanization of 7 two parts of metalwork, main spring metalwork inner periphery is provided with semicircle helicla flute, and the both ends of main spring are pressed with auxiliary
Spring, auxiliary spring are also corresponding with main spring integral by rubber 3 and the vulcanization of 8 two parts of metalwork, mandrel excircle and main spring
Metalwork inner periphery upper semi-circle helicla flute is corresponding to be also provided with semicircle helicla flute, and the metalwork part of main spring and mandrel are fitted in one
It rises, two semicircle helicla flute engagements constitute helical cavity, and oil liquid pipeline 4 is placed in helical cavity, and main spring and auxiliary spring periphery are pressed with
Housing sets two oil pockets 5 using mandrel as symmetry axis between housing and main spring, two oil pockets respectively with corresponding oil liquid pipeline
Two-port communicate.Oil pocket is had nothing in common with each other in different location size shape, left side oil pocket cross section be from top to bottom it is big-small-big-
Small sequence variation, right side oil pocket cross section is small-big-small-big sequence variation from top to bottom, to adapt to the resistance of different line requirements
The size of Buddhist nun's power.
Referring to Fig. 3, pivoted arm node 9 of the present invention is mounted on railway vehicle bogie primary location structure, with pivoted arm 10, one
Be steel spring 11, one it is that damper 12 collectively forms system positioning, system positioning is made to adapt to straight path and curve circuit not
With requirement, dynamics of vehicle performance is improved.
Working principle: when vehicle is run on straight path in high frequency, variation rigidity pivoted arm node bears biggish vertical
Xiang Li generates compressive deformation under the action of longitudinal force positioned at longitudinal oil pocket, to oppress the liquid in oil pocket, makes in oil pocket
Liquid from a chamber along another chamber of oil liquid pipeline flow-direction, liquid flows in the duct, just generates damping force, then
Dynamic stiffness is generated, which is that fluid damping generates being superimposed for rigidity and the rubber stiffness of main spring rubber part；When vehicle exists
When operation is in low frequency on curve circuit, variation rigidity pivoted arm node bears lesser longitudinal force, and the compressive deformation that oil pocket is subject to is very
Small, oil liquid flowing velocity is very slow, the dynamic stiffness that oil liquid damping generates very little compared with main spring rubber part rigidity, entire to become
The rigidity of rigidity pivoted arm node is approximately equal to the rigidity of main spring rubber part, i.e. Static stiffness.For different line conditions, become rigid
Degree pivoted arm node can provide the longitudinal rigidity value for adapting to corresponding line, to meet rail vehicle high-speed cruising stability and curve
The dynamics demand of passage capacity.
