Description
Technical field
The present invention relates to a kind of rolling stock draw gear, relate in particular to a kind of six bar draw geares of railway locomotive.
Background technology
Six bar draw geares are widely used in China's east wind and Shaoshan series passenger and freight locomotive, all adopt this device as principal mode locomotive DF4, DF8, DF11, SS3, the SS9 of present railway transportation.It is a kind of six-bar mechanism, and the rear end of left and right draw bar links to each other with car body, the hinged left and right connecting lever of the front end of left and right draw bar difference, and the other end of left and right connecting lever is hinged with the two ends that are connected cross bar respectively; Simultaneously, the corner of left and right connecting lever links to each other with bogie truck by the connecting lever pin.The draw bar of six-bar mechanism is positioned at the bogie truck both sides, helps the layout of middle other structure of bogie truck, and is widely used in three axle truck.But this device respectively connect the joint and rod member all adopts hard parts, make car body and bogie truck in the vertical for being rigidly connected.When locomotive startup, braking and longitudinal impulse in service and vibration, the junction of six bar draw geares and bogie truck and car body, each rod member of draw gear all bear bigger longitudinal impact load, it has reduced the safety of draw gear and the service life of associated components, influence the stationarity of locomotive longitudinal traction, and influence the wheel rail adhesion state of drive wheel to a certain extent.
Summary of the invention
Purpose of the present invention just provides a kind of elastic vibration reduction towing mechanism of track vehicle, this draw gear can be alleviated the longitudinal impact of locomotive effectively, improve the safety and the longitudinal traction stationarity of locomotive operation, and improve the service life of draw gear and junction thereof.Can on the basis of the rigidity six bar draw geares that have locomotive now, transform easily, save cost.
The present invention realizes its goal of the invention, the technical scheme that is adopted is: a kind of elastic vibration reduction towing mechanism of track vehicle, comprise a left side that links to each other with car body, right draw bar, with a left side, right draw bar is a pivotally attached left side respectively, the arm of turning right, a left side, the turn right corner of arm links to each other with bogie truck by the connecting lever pin, its constructional feature is: a left side, the arm of turning right is linked to each other by elastic connector, specifically constituting of elastic connector: the left part of left connecting rod is hinged with the arm of turning left, the right part of left side connecting rod is with the spring guide of band spring cavity outward, the right-hand member of spring guide links to each other with right connecting rod, and the right-hand member of right connecting rod is hinged with the arm of turning right; The right part of left side connecting rod is respectively equipped with left and right positive stop lug boss corresponding to the spring cavity end positions of spring guide, and there is the boss mobile cavity that cooperates with left and right positive stop lug boss spring guide inboard; The inboard of the left and right positive stop lug boss of left side connecting rod also is provided with sliding block; Spring cavity position in the sliding block is provided with the recoil spring of pretension.
Working process of the present invention and principle are:
When longitudinal impact or vibration take place in locomotive in startup, braking and operational process, produce longitudinally between left and right sides draw bar and the left and right sides connecting lever and impact, the transverse arm that left and right sides connecting lever is linked to each other with draw bar rotates simultaneously forward or backward, vertical arm of its left and right sides connecting lever then outwards or inwardly rotates simultaneously, thus outwards stretching or the inwardly elastic connector of crimp connection left and right sides connecting lever.
Elastic connector is pulled outwardly when stretching, left side connecting rod and spring guide be outwards motion under the effect of connecting lever, correspondingly the spring guide drives left sliding block and moves right, left side connecting rod and right limit boss drive right sliding block to left movement, the recoil spring that horizontally slips between block is compressed, thereby longitudinal impact is alleviated.
When elastic connector is extruded inward, left side connecting rod and spring guide be inwardly motion under the effect of connecting lever, correspondingly the spring guide drives right sliding block to left movement, left side connecting rod and left limit boss drive left sliding block and move right, the recoil spring that horizontally slips between block is compressed, thereby longitudinal impact is alleviated.
As seen, no matter be longitudinal impact forward or backward, all alleviated in the compressed mode of recoil spring by elastic connector of the present invention.
Compared with prior art, the invention has the beneficial effects as follows:
The longitudinal impact that car body is subjected to is alleviated in longitudinal impact and vibration when one, utilizing elastic connector effectively to absorb locomotive operation greatly, plays the effect of longitudinal damping, improves the safety and the longitudinal traction stationarity of locomotive operation; And the impact of draw gear self and junction thereof is also retarded, and improve service life.Two, utilize ingenious design-calculated elastic connector will be forward or longitudinal impact backward or vibration all absorb in the compressed mode of recoil spring, rather than adopt the compression of spring mode to absorb a kind of impact, and absorb oppositely directed impact in the elongation mode, thereby can make spring be in the pretension state at reset mode, predetermincd tension can be regulated, each parts that had both guaranteed whole elastic connector are connected firmly, closely, long service life, guarantee again tractive force effectively, reliable delivery.Three, change the horizontal pipe link in the existing six bar draw geares into elastic connector of the present invention, can realize the transformation of existing locomotive, simple to operate, cost is low, helps the utilization and extention of apparatus of the present invention.
Above-mentioned recoil spring is an annual spring, be made of the inner and outer rings spring, the radius of outer ring spring is greater than inner ring, and the inside in outer ring spring cross section is inside diminishing taper, the outside in inner ring cross section is outside diminishing taper, and inner and outer rings spring from coil to coil is in contact with one another chimeric.
When recoil spring is subjected to force compresses, make and respectively encircle mutual extrusion, outer shroud dilates, interior ring compression, and make spring when producing axial deformation, also produce radial deformation, and part kinetic energy is transformed into elastic potential energy, play the effect of impacting that relaxes, each inside and outside cup spring falls because of the mutual extrusion friction becomes the part impact energy into thermal dissipation between the inclined-plane that is in contact with one another in deformation in compression simultaneously; In the reseting procedure after external force is removed, produce friction between each cup spring again, change the part of stored energy into frictional heat energy again and dissipate.Evidence, the recoil spring that inner and outer ring spring of the present invention constitutes can reach 60%～70% by the used up energy of friction in loading and uninstall process.As seen the spring of this structure can more obviously reduce the shock and vibration between car body and the bogie truck, and rolling stock is operated steadily.
The right limit boss of above-mentioned left connecting rod is positioned at the right part of left connecting rod, and is connected on the left connecting rod by screw.
Above-mentioned spring guide is made of left and right two parts, and left and right two parts are with bolted connection.
Elastic connector installation and maintenance of the present invention like this are convenient easily.
The present invention is described in further detail below in conjunction with accompanying drawing and concrete embodiment.
