Description
Technical field
The present invention relates to rail vehicle truck technical field, especially relate to a kind of major-minor framework elastic hinge joint
Radial steering.
Background technology
Traditional bogie uses H type framework, rigid beam, only rely on one be vertical flexibility overcome circuit
Distortion, the ability that bogie adapts to circuit distortion is poor.
Find through retrieval, Chinese invention patent CN101565049B, it discloses a kind of frame of hinged frame linear electric motor
Bogie, two T-shaped frameworks are hinged with curb girder by rubber nodal point respectively；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, its crossbeam all cannot carry, it is impossible to the frame realizing motor is outstanding thus improves
The desin speed of bogie, improves dynamic performance during bogie high-speed cruising.
Conventional bogie is taken turns as taking into account stability, should not arrange too small to locating stiffness, thus limit on curve
Wheel, to the ability guided by creep moment, causing wheel to there is the angle of attack during by curve, producing wheel-rail wear and curve
" utter long and high-pitched sounds ".Adding the bogie after forced guiding mechanism, its curving performance is improved, but because of guiding mechanism
Complicated and existence is worn and torn, and thus fails to significantly improve bogie by properties during curve.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and a kind of major-minor framework bullet is provided

Structure.Rubber pin nested structure, has bigger lateral stiffness, rubber metal pad laminated construction, has less lateral stiffness,
Combination of the two can be suitable for when bogie is by curve, the lateral deflection between major and minor framework.
Being additionally provided with radially actuator between described main truss and secondary framework, one end of this radial direction actuator connects main structure
Frame, other end auxiliary connection framework；
During work, radially actuator promotes main truss and secondary framework, makes to produce between main truss with secondary framework relative returning
Corner, and then driven wheel is to being in radial position.
Described main truss is herringbone, and its head is connected with secondary framework by elastic hinge joint assembly；
Described secondary framework is in the square frame-shaped with fish belly type structure.
The afterbody of described main truss is provided with crossbeam, and portion is divided into middle boxes and tail frame, in described
Between the centrepin drawing pull bar device being connected with car body is set in frame, arrange in tail frame take turns right.
It is equipped with anti-side rolling torsion rod, respectively main truss anti-side rolling torsion rod and secondary structure on described main truss and secondary framework
Frame anti-side rolling torsion rod.
Compared with prior art, the invention have the advantages that
(1) bogie uses the major and minor framework connected by elastic hinge joint assembly to form, and main truss is the most secondary
Framework uses the form of supported at three point location, so makes bogie have preferable flexibility function, thus adapts to line
It is very capable that road distorts.
(2) being provided with the radial direction actuator of the most radially function on bogie, when crossing curve, radially actuator promotes
Major and minor framework, make major and minor framework produce relative angle of revolution, major and minor framework driven wheel again to being in radial position,
Improve bogie curve negotiation ability.
(3) whole bogie structure is simple and reliable, parts can modularized production, there is replaceability, it is simple to system
Make and safeguard, reducing production cost.
