Description
Technical field
The utility model belongs to rail vehicle truck technical field.
Background technique
In rail vehicle, suspension arrangement of the single stage suspension between axle box and bogie transmits mutual vertical, transverse direction
And longitudinal force.The vertical stiffness of single stage suspension is mainly used for decaying vibration as caused by the vertical irregularity of track and impacts,
Vertical and horizontal rigidity is used for the positioning of axle box, influences the hauling ability, linear running stability and curve negotiating of vehicle,
The matching of parameter is directly related to the runnability of rail vehicle.The design requirement of single stage suspension structure, in a limited space
It realizes the Proper Match of vertical and horizontal stiffness parameters, while guaranteeing suitable vertical natural bow, to ensure that it is excellent that bogie has
Good dynamic performance.
At present modern vehicle frequently with single stage suspension positioning method, mainly include pivoted arm, single pull rod type, V-arrangement lamination
Rubber spring type and drawplate type etc..
Pivoted arm single stage suspension is mainly made of tumbler axle-box, rubber arthrosis and overhead coil spring；Overhead spring provides one
It is vertical stiffness, vertical and horizontal rigidity is provided by the rubber arthrosis in pivoted arm joint；The major defect of the suspended structure: framework side
Beam and structure of axle box are complicated, and unsprung mass is larger, and the natural bow of overhead spring is smaller.
Single pull rod type single stage suspension is mainly made of the pull rod of axle box, coil spring and both ends installation rubber arthrosis；One system hangs down
It is provided to lateral stiffness by spring, longitudinal rigidity is provided by rubber arthrosis；The major defect of the suspended structure: the cross of spring
It is coupled to vertical stiffness, it is difficult to while realizing best design objective, it is typically used in and needs smaller one vehicle for being natural bow.
V-arrangement laminated rubber spring formula single stage suspension is made of two groups of V-arrangement laminated rubber springs, two groups of spring inverted V-shaped arrangements
In axle box two sides, provide axle box longitudinally, laterally and vertical stiffness；The major defect of the suspended structure: due to laminated rubber bullet
Spring is respectively coupled to elastic parameter, it is difficult to realize the accurate matching of the three-dimensional elastic parameter of a system, in addition the aging and creep of rubber
It is also undesirable.
There are three types of types for drawplate type single stage suspension at present: standard Ming Dengshi [I type], S-shaped Ming Dengshi [II type] and IS formula [III
Type], it is all made of double pulling plate positioning axle boxes.The suspension of I type, respectively installs a pulling plate in axle box two sides, bolt is used at pulling plate both ends respectively
It is rigidly fixed on axle box and truck side sill, two groups of coil springs are arranged in axle box two sides；The suspension of II type installs two in axle box side
Root pulling plate, pulling plate both ends are respectively bolted on axle box and truck side sill, and single group coil spring overhead is on axle box；III type is outstanding
Extension is the modified to I type, in the connecting pin of pulling plate and framework, accesses rubber element, to improve the stress of pulling plate, other
Structure is identical as I type.The locating stiffness in length and breadth of I type and II profile shaft case is provided by the rigidity in length and breadth of pulling plate；The installation of III profile shaft case
The locating stiffness in length and breadth at end is mainly provided by rubber arthrosis rigidity.The major defect of Ming Dengshi suspension: pulling plate need to occupy biggish
The pulling plate of longitudinal space, I type and II type need to meet the stiffness parameters in length and breadth of single stage suspension simultaneously, and need to consider the stability of pulling plate
And intensity, design difficulty are larger.
