Description
Technical field
The present invention relates to rolling stock structure design field, be applied to be specially a kind of torsion rod type self guide mechanism of radial steering frame on the rolling stock bogie truck.
Background technology
Along with Heavy-Haul Railway, high speed development, wheel-rail wear and safety problem are more outstanding, and the requirement that improves the rolling stock curving performance is particularly urgent.Yet conventional rolling stock bogie truck improves its lateral stability and improves curving performance is conflicting always, adopts radial steering can solve this problem well.Radial steering can reduce wheeling edge wearing and transverse force when guaranteeing locomotive linear running stability, reduce specific consumption of fuel, satisfy the requirement of curving performance and lateral stability two aspects simultaneously, speed when improving train by curve is improved the adhesive performance of rolling stock on curve.Self guide mechanism is a gordian technique of radial steering, effect by self guide mechanism can reduce the right angle of attack of wheel, thereby make wheel-rail lateral force each take turns between reasonably distributed, make front and back wheel in by curve, having the radial position ability that is tending towards curve, thus the stability when improving rolling stock greatly by curve.
In recent years, various countries competitively carry out the radially research of bogie truck, have obtained certain effect, have begun to enter practical stage, and this respect development ratio country faster mainly contains the U.S., Germany, Switzerland, South Africa etc.Current, the wheel of the most of rolling stock that travels on China's circuit is bordering on being connected of rigidity to still adopting in the vertical with framework, and promptly front and back wheel is parallel to remaining in the operational process.When rolling stock when the curve track, wheel is to the position of keeping parallelism still in framework, make wheel to and track between the angle of attack bigger, produce bigger horizontal force between wheel track, thereby wheel-rail wear is serious, rolling stock adhesive performance on curve descends.Solve this contradiction, adopting the radial steering technology is a desirable approach.It not only has steering capability preferably on curve, and on straight line, owing to there is the hydraulic damper that is installed on the pivoted arm to provide bigger wheel to locating stiffness, makes bogie truck that the good anti-stability of crawling be arranged again.
The self guide mechanism bogie truck is the guiding mechanism that utilizes front and back wheel right, the motion of shaking the head that front and back wheel is right is coupled together, utilize vertical creep power of left and right wheels poor, front-wheel is right to by the curve hour wheel trend that is tending towards radial position oppositely being sent to trailing wheel, make front and back wheel to by curve the time, all being tending towards the curve radial position, reduce the wheel track horizontal force to reach, reduce to take turns purpose the angle of attack and wheel-rail wear.
Chinese patent CN200720129909.2 discloses a kind of passenger car bogie radial guide means, and its composition comprises: two pilot bars, mount pad, guiding damper, guiding damper seat.
Chinese patent CN03148641.X discloses a kind of radial steering device, and its structure is as follows: preceding steering beam links together by the connecting rod left and right axle box that front-wheel is right, and back steering beam links together by the connecting rod left and right axle box that trailing wheel is right.Two steering beams link together by big connecting rod again, thus realize front and rear wheel to interlock.
U.S. Pat 4679506 discloses locomotive (the Railway truck with improved steering linkage of a kind of improved steering swivel system, detachable suspension and traction motor braking, detachablesuspension and traction motor mounted brake), its structure is: the right side shaft case of front-wheel links together by pull bar and the trailing wheel axle box to the same side, realizes interlock.
Yet there is not central torsion bar structure in above-mentioned three kinds of guide piece structures, still can not limit effectively front and back wheel to vertical relative displacement, be easy to generate front and back wheel between the motion of shaking the head relatively, cause train guiding mechanism when high-speed cruising to produce fierce vibration.
Summary of the invention
Can produce the defective of fierce vibration at existing locomotive guiding mechanism when the high-speed cruising, the present invention aims to provide a kind of torsion rod type self guide mechanism of radial steering frame, it can suppress effectively front and back wheel between vertical relative displacement, simultaneously when front and back wheel between when motion of shaking the head relatively arranged, keep front and back wheel to being tending towards the radial position of curve as far as possible simultaneously, make rolling stock on straight line and curve, all have good running stability.
The technical solution adopted in the present invention: a kind of torsion rod type self guide mechanism of radial steering frame that is used for rolling stock, comprise the pilot bar that is arranged in the framework both sides, an end of every pilot bar links to each other with an axle box respectively; Its constructional feature is, this mechanism also comprises the central torsion bar that is installed in the framework center, and the pivoted arm that is arranged in the framework both sides and connects with central torsion bar two ends respectively, and the two ends of pivoted arm are hinged with the pilot bar symmetry respectively.
Described pivoted arm one end links to each other with an end of hydraulic damper, and the other end of this hydraulic damper is fixed on the framework, the motion of shaking the head of vertical high-frequency vibration that the front and back wheel that can decay is right and high frequency.
Be equipped with being threaded of its length of scalable in the middle of the described every pilot bar, be used to regulate its length, make the pilot bar length unanimity about framework.
All be equipped with flexible joint between described central torsion bar and framework, pilot bar and pivoted arm, pilot bar and axle box, pivoted arm and the hydraulic damper.Flexible joint between wherein central torsion bar and the framework is the torsion bar ball pivot, and this torsion bar ball pivot is by ring inner sleeve, ring-shaped jacket and place ring inner sleeve and ring-shaped jacket between rubber ring form.The employing flexible joint connects, and inter-agency have big radial rigidity and a little torsional stiffness, big radial rigidity for wheel to big longitudinal rigidity is provided, make rolling stock on straight line, have good running stability; Little torsional stiffness makes wheel to being free to rotate with pilot bar, central torsion bar.
The angle of rotation of described two pivoted arms is identical, can keep front and back wheel to being tending towards the radial position of curve as far as possible simultaneously.
According to embodiments of the invention, the pilot bar of framework both sides couples together by central torsion bar and pivoted arm, wherein central torsion bar is connected by the spline press-fit with pivoted arm, and be fixed together by nut, but actv. restriction front and back wheel to vertical relative displacement, guiding mechanism produces fierce vibration when having avoided the train high-speed cruising.
Beneficial effect of the present invention: have the ability that is tending towards radial position when 1, the invention enables front and back wheel by curve, and the motion of shaking the head of the right vertical high-frequency vibration of the front and back wheel that can decay and high frequency.
But 2, the present invention's actv. restriction front and back wheel to vertical relative displacement, guiding mechanism produces fierce vibration when having avoided the train high-speed cruising, keeps front and back wheel to being tending towards the radial position of curve as far as possible simultaneously simultaneously.
