Abstract
A kind of single stage suspension composition of arrangement three-dimensional decoupling type in the same direction, is characterised by altogether：Including 3 springs, vertical placement, longitudinal arrangement, center is helical steel springs, for undertaking vertical load, there is provided vertical stiffness；Two rubber springs are located at helical steel springs both sides, and are centrosymmetric arrangement with helical steel springs, and one of rubber spring is used for the longitudinal register effect for undertaking axle box, there is provided longitudinal rigidity；Another rubber spring is used for the located lateral effect for undertaking axle box, there is provided lateral stiffness.The present invention realizes the separation of single stage suspension vertical stiffness, Longitudinal stiffness and transverse stiffness, decouples three-way rigidity；Second, greatly reducing the diameter dimension of single spring, so as to reduce occupancy of the spring to bogie horizontal space, the space arrangement of bogie built in axle box is advantageous to.
Description
Technical field
The invention belongs to technical field of rail traffic, more particularly, to a kind of single stage suspension structure group for bogie
Into.
Background technology
Bogie is generally made up of, wherein single stage suspension forms as carrying, vibration damping and running mechanism two suspension
Positioned at wheel pair between framework, major function is carrying, vibration damping and positioning action, is the critical component of bogie.Existing steering
Frame single stage suspension composition has two kinds of primary structure forms：First, rubber spring；Second, helical steel springs.Wherein rubber spring uses
In subway, light rail vehicle, suitable for low speed, small axle weight bogie, rubber spring is characterized in addition to vertical carrying, can be with
Play a part of axle-box locating, that is, certain longitudinal register and located lateral rigidity are provided, its shortcoming is that rubber spring has late
Stagnant characteristic, dynamic vertical stiffness excursion is larger, and vertical stiffness, Longitudinal stiffness and transverse stiffness influence each other, mutually
Association, it is impossible to decouple；Steel spring is used for subway, intercity, EMU vehicle, is weighed suitable for big axle, typotron, its
Feature is that steel spring only provides vertical stiffness, and vertical stiffness is held essentially constant under different loads operating mode and bearing capacity is strong,
Its shortcoming is that steel spring can not provide longitudinal register rigidity and located lateral rigidity, and axle-box locating need to use pivoted arm axle-box locating
Or rod-pulling type positioning, make the complicated and space-consuming of axle-box locating larger.Above two single stage suspension mode is in order to meet
The requirement of vertical carrying, the diameter of single spring is larger, takes the horizontal space of bogie.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of single stage suspension composition of new construction, to overcome an existing system
Suspension composition is in terms of stiffness coupling, space structure complexity the defects of.
In order to solve the above technical problems, the present invention provides one kind arrangement three-dimensional decoupling type single stage suspension composition in the same direction, it is special altogether
Sign is：Including 3 springs, vertical placement, longitudinal arrangement, center is helical steel springs, for undertaking vertical load, is carried
For vertical stiffness；Two rubber springs are located at helical steel springs both sides, and are centrosymmetric arrangement with helical steel springs, wherein one
Individual rubber spring is used for the longitudinal register effect for undertaking axle box, there is provided longitudinal rigidity；Another rubber spring is used to undertake axle box
Located lateral effect, there is provided lateral stiffness.
The present invention undertakes vertical load by the helical steel springs of center, there is provided vertical stiffness.Both sides rubber spring
In one undertake axle box longitudinal register effect, there is provided longitudinal rigidity；The transverse direction that another rubber spring mainly undertakes axle box is determined
Position effect, there is provided lateral stiffness.The separation of single stage suspension vertical stiffness, Longitudinal stiffness and transverse stiffness is realized, makes three-dimensional firm
Degree decoupling；Second, greatly reduce the diameter dimension of single spring, so as to reduce occupancy of the spring to bogie horizontal space, ten
Divide the space arrangement for being advantageous to bogie built in axle box.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Reference picture 1, the specific embodiment of the invention include vertical carrying helical steel springs 1, longitudinal register rubber spring 2,
3,3 springs of located lateral rubber spring are placed vertically, longitudinal arrangement, and center is helical steel springs, vertical for undertaking
Load, there is provided vertical stiffness；Two rubber springs are located at helical steel springs both sides, and are centrosymmetric cloth with helical steel springs
Put, one of rubber spring 2 is used for the longitudinal register effect for undertaking axle box, there is provided longitudinal rigidity；Another rubber spring 3 is used
Acted in the located lateral for undertaking axle box, there is provided lateral stiffness.The innovation that single stage suspension composition is arranged in the same direction using 3 springs
Structure design, realize two major functions：First, realize point of single stage suspension vertical stiffness, Longitudinal stiffness and transverse stiffness
From decoupling three-way rigidity；Second, the diameter dimension of single spring is greatly reduced, it is laterally empty to bogie so as to reduce spring
Between occupancy, be advantageous to bogie built in axle box space arrangement.
Claims (1)
