Description
Technical field
The present invention relates to rail vehicle truck technical field, more particularly, to a kind of radial direction of major-minor framework elastic hinge joint
Bogie.
Background technology
Traditional bogie uses H-type framework, and rigid beam, it is the distortion that vertical flexibility overcomes circuit to only rely on one,
The ability that bogie adapts to circuit distortion is poor.
Find that Chinese invention patent CN101565049B, it discloses a kind of steerings of frame of hinged frame linear electric motor through retrieval
Frame, two T-shaped frames are hinged respectively by rubber nodal point and curb girder；Another Chinese invention patent CN102975734A, it discloses
A kind of permanent magnet direct-drive compliance steer frame with central sill flexibility plank frame.
The flexible frame of both forms, crossbeam can not carry, and can not realize that the frame of motor hangs and be turned to so as to improve
The desin speed of frame improves dynamic performance during bogie high-speed cruising.
Conventional bogie wheel should not set locating stiffness too small to take into account stability, thus limit wheel pair on curve
By the ability that creep torque is oriented to, there are the angles of attack when leading to wheel to passing through curve, generate wheel-rail wear and curve " uttering long and high-pitched sounds ".Addition
Bogie after forced guiding mechanism, curving performance are improved, but because guiding mechanism is complicated and there is abrasion, therefore not
Properties when bogie passes through curve can be significantly improved.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of major-minor framework elasticity
Hinged radial steering.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of radial steering of major-minor framework elastic hinge joint, main truss and pair including connecting and forming steering frame body
Framework, elastic hinge joint component is equipped on the secondary framework, and the main truss passes through elastic hinge joint component and connects with secondary framework
It connects；
Installation wheel pair on main truss, the supported at three point that the relatively secondary framework of main truss forms " taking turns p- elastic hinge joint component " are determined
Position.
The elastic hinge joint component includes two rubber arthrosis being located on bogie pivot center axis, respectively the first rubber
Glue joint and the second rubber arthrosis, first rubber arthrosis and the second rubber arthrosis are to move closer to the side of bogie pivot center
Formula is distributed.Using rubber arthrosis as elastic hinge joint device, using the low characteristic of rubber arthrosis torsion stiffness, major and minor structure is realized
Frame is decoupled around X-axis, realizes the flexibility of framework.Rubber arthrosis has certain lateral, vertical, longitudinal rigidity simultaneously, ensures framework
Relative Displacement ability between whole carrying, driving power and major and minor framework.
First rubber arthrosis is rubber pin nested structure, and second rubber arthrosis is rubber metal pad laminated construction.
Rubber pin nested structure, has larger lateral stiffness, and rubber metal pad laminated construction has smaller lateral stiffness, the group of the two
Conjunction can be applicable in when bogie passes through curve, the lateral deflection between major and minor framework.
Radial direction actuator is additionally provided between the main truss and secondary framework, one end of the radial direction actuator connects main structure
Frame, other end auxiliary connection framework；
During work, radial direction actuator pushes main truss and secondary framework, makes to generate opposite revolution between main truss and secondary framework
Angle, and then with driving wheel to being in radial position.
The main truss is in herringbone, and head is connect by elastic hinge joint component with secondary framework；
The secondary framework is in the square frame-shaped with fish belly type structure.
The tail portion of the main truss is equipped with crossbeam, and tail portion is divided into middle boxes and tail frame, in the centre
The centrepin drawing pull bar device that setting is connect with car body in frame, the setting wheel pair in tail frame.
Anti-side rolling torsion rod, respectively main truss anti-side rolling torsion rod and secondary framework are equipped on the main truss and secondary framework
Anti-side rolling torsion rod.
Compared with prior art, the present invention has the following advantages：
(1) bogie is used is made up of the major and minor framework that elastic hinge joint component connects, and the relatively secondary framework of main truss is adopted
The form positioned with supported at three point, so that bogie has preferable flexibility function, so as to adapt to the ability of circuit distortion
It is very strong.
(2) the radial direction actuator of active radial direction function is installed, radial direction actuator pushes major and minor when crossing curve on bogie
Framework makes major and minor framework generate opposite angle of revolution, and band driving wheel to being in radial position, improves bogie curve to major and minor framework again
Handling capacity.
(3) entire bogie structure is simple and reliable, component can modularized production, there is replaceability, convenient for manufacturing and tieing up
Shield, reduces production cost.
