Description
Technical field
The invention belongs to rail vehicle truck technical field of structures, particularly relate to independently rotated take turns to bogie structure
Technical field.
Background technology
The tradition coaxial fast pulley of rail truck is good to curve orientation, straight line centering strong, but exists and crawl, critical velocity
Low.Independently rotating wheel crawls owing to not existing, and its critical velocity is high, and can realize low-floor.Because there is not longitudinal direction
Creep moment, independently rotating wheel can not reset from trend orbit centre, when being encouraged by track irregularity, independently rotated car
The wheel track side that can recline travels and produces wheel rim contact, thus causes wheeling edge wearing serious, even causes derailing security incident.Turn
Guiding, to frame, the difficult problem that problem is puzzlement independent wheel bogie development, various countries are the guiding solving independent wheel bogie
Sex chromosome mosaicism defines diversified developmental pattern.Wherein, lateral independent wheel bogie and Longitudinal data independent wheel turn
Being widely used with the advantage that the guiding mechanism of its simple in construction is relatively low with cost to frame, Longitudinal data needs to join
Put motor as power, be only suitable for motor-car, lateral independent wheel bogie Directing Mechanism of V-notchf Withjn and conventional rigid wheelset guiding machine
Manage identical.
In terms of main line railway, the bullet train NGT of future generation of German Aerospace Center DLR exploitation, by only with single shaft
Vertical swivel wheel bogie, it is expected to realize the conception of double-layer high-speed train, will greatly improve the utilization economy of bullet train.Right
In high-speed line, sweep is big, and the guiding problem of independent wheel bogie does not highlight, automatic to orbit centre on straight line
The ability resetted is only important.Existing lateral independent wheel synchronizes left and right wheels by set of gears drive mechanism
Rotating speed, this is a kind of close coupling mechanism, in addition to reducing floor level, performance and ordinary wheel to being as good as, this external gear mechanism
Adding one is that the weight under spring exacerbates wheel track intermolecular forces, is unfavorable for running at high speed.
Summary of the invention
It is an object of the invention to provide a kind of rail vehicle independently rotated take turns to bogie structure, it can efficiently solve
The problem that when using gear drive, lateral independent wheel bogie exists.
It is an object of the invention to be achieved through the following technical solutions, a kind of rail vehicle is independently rotated take turns to turn to
Shelf structure, right including framework and wheel, the two ends diameter of axle of wheel shaft and the internal ring interference fit of rolling bearing, the outer shroud of rolling bearing with
Wheel hub is fixed, and is axially arranged with secondary tread outside wheel hub, and the two ends spindle nose of wheel shaft is provided with spindle nose cover；Two side girders of framework are bow word
Shape structure, lateral arrangement；The two ends of front beam are fixed at the longeron bow font first stroke of a Chinese character, and the two ends of rear cross beam are received with longeron bow font
At Bi fixing, the front end of the anterior breach down of longeron is provided with level to elastic restraint front part, and the top of longeron breach down sets
Vertical spring constraint front part, the rear end of longeron breach down is had to be provided with friction pair front support seat；Level is structure before elastic restraint
The free end of part and the free end of vertical spring constraint front part respectively with the level of spindle nose cover to and vertical to fixing；After longeron
The setting of the vertical spring constraint rear part in portion is identical with longeron front portion structure, and level is after elastic restraint rear part and friction pair
The setting supporting seat is contrary with longeron front portion structure；The two ends of countershaft are provided with bearing block, and the inner side of bearing block is provided with pressure wheel, executes
Pinch roller is with secondary tread external diameter is tangent arranges composition friction pair；It is equipped with level in friction pair front support seat and friction pair rear support seat
To elastic component, level arranges bearing block to the end of elastic component with countershaft end and fixes.
The diameter of described secondary tread is less than the diameter of wheel hub.
Described elastic component is spring member or hydraulic component.
Compared with existing lateral independent wheel technology, the invention has the beneficial effects as follows: lateral is with friction pair generation
For gear pair improve take turns to critical velocity, the secondary tread of wheel hub side can with brake disc share, be effectively reduced under spring
Quality thus reduce the dynamic deformation from motion between wheel track, provide a kind of novel steering frame for double-layer high-speed train.
