As shown in Figure 4 and Figure 5, the bogie truck that provides of embodiment comprise wheel to 1, single stage suspension system 2, framework 3, two be central mounting system 4, bolster 5.Its each several part annexation is same as the prior art, has the truck center plate that matches with lorry body on the bolster 5, and by two is the middle part that central mounting system 4 is installed in framework 3, framework 3 is installed in wheel on 1 by single stage suspension system 2, wheel can match with track to 1, and supporting in orbit.Wherein, two is that longitudinal towing mechanism 6 in the central mounting system 4 is different with the prior art longitudinal towing mechanism.
As shown in Figure 6 and Figure 7, described longitudinal towing mechanism 6 comprises drawing pull bar 60 and two draw- bar seats 61,62, links to each other by ball pivot assembly 63 respectively between draw- bar seat 61,62 and the drawing pull bar 60.For the convenience of describing, draw-bar seat 61 is called first draw-bar seat, draw-bar seat 62 is called second draw-bar seat; First draw-bar seat 61 is fixing with bolster 5, and second draw-bar seat 62 is fixing with framework 3.
With reference to figure 4 and Fig. 5, in this example, have lower cover 51, the first draw-bar seats 61 tops on the bolster 5 and have the dull and stereotyped 61-1 that matches with lower cover 51 lower planes again, dull and stereotyped 61-1 and lower cover 51 are fixing by welding.It will be understood by those skilled in the art that first draw-bar seat 61 and the fixing of bolster 5 can also adopt other modes to realize, such as: dull and stereotyped 61-1 and lower cover 51 can be connected and fixed by fastener.In this example, have the crossbeam 31 of lateral arrangement on the framework 3, framework 3 outsides are stretched out at crossbeam 31 two ends; Second draw-bar seat, 62 tops have pull bar frame 62-1, and pull bar frame 62-1 endoporus matches with crossbeam 31 outer peripheral faces, when mounted, pull bar frame 62-1 are enclosed within on the crossbeam 31, and are in the mode of boxing that pull bar frame 62-1 and crossbeam 31 is fixing again.It will be understood by those skilled in the art that and to adopt other modes that second pull bar 62 and framework 3 are fixed.
Annexation between longitudinal towing mechanism 6 and bolster 5 and the framework 3 has below been described respectively, below to the structure of the ball pivot assembly 63 of longitudinal towing mechanism 6, and between ball pivot assembly 63 and first draw-bar seat 61, second draw-bar seat 62 and the drawing pull bar 60 specifically annexation be described.
As Fig. 8, ball pivot assembly 63 comprises ball pivot axle 63-1, ball pivot cover 63-2 and hinged middle cover 63-3.The centre of ball pivot axle 63-1 and ball pivot cover 63-2 has sphere curved surface respectively.In this example, the sphere curved surface of ball pivot axle 63-1 middle part is outer convex surface, and the sphere curved surface of ball pivot cover 63-2 is an inner sunken face, and ball pivot axle 63-1 and ball pivot overlap 63-2 by the outer convex surface that cooperatively interacts with inner sunken face is hinged cooperates.In order to make ball pivot assembly 63 have bigger elastic deformation amount, in this example, also be provided with the hinged middle cover 63-3 that makes with elastomeric material outside between convex surface and the inner sunken face, cover 63-3 can produce corresponding elastic deformation in hinged, thereby can buffering ball hinge 63-1 and ball pivot cover 63-2 between impact, guarantee the stability of tractive force transmission between bolster 5 and the framework 3.
The ball pivot cover 63-2 outside is a cylindroid, has a mounting hole respectively at drawing pull bar 60 two ends; Be interference fit between described cylindroid and the mounting hole, this interference fit is fixed ball pivot cover 63-2 and drawing pull bar 60 ends.Adopt the mode of interference fit that drawing pull bar 60 is fixed with ball pivot cover 63-2, can facilitate for the installation of longitudinal towing mechanism 6 on the one hand; Can increase the maintainability performance of longitudinal towing mechanism 6 on the other hand, after ball pivot assembly 63 damages, can easily ball pivot assembly 63 be changed.It will be understood by those skilled in the art that the ball pivot cover 63-2 and the fixed form of drawing pull bar 60 can also adopt other concrete structures, such as: also can ball pivot be overlapped 63-2 and drawing pull bar 60 is fixed by the mode of welding; Fixed sturcture can be identical between drawing pull bar 60 two ends and the ball pivot cover 63-2, also can be different.
As Fig. 8, in the axial direction, ball pivot axle 63-1 stretches out fixed flat planar 63-11 respectively to two ends, and first draw-bar seat 61 stretches out two fixed flat planar 61-2 downwards; Fixed flat planar 63-11 and fixed flat planar 61-2 are parallel to each other, and fixing by bolt 7, and first draw-bar seat 61 is fixed together with ball pivot axle 63-1.In this example, the ball pivot axle 63-1 two ends and first draw-bar seat 61 are fixing, can increase the ability of longitudinal towing mechanism 6 transfer function power.In this example, also adopt same structure to be fixed together between the ball pivot axle 63-1 and second draw-bar seat 62.
With first draw-bar seat 61 and second draw-bar seat 62 with ball pivot axle 63-1 fixing after, the relative position of two draw-bar seats has just been determined.According to the description of background parts, in the time of on first draw-bar seat 61 and second draw-bar seat 62 being separately fixed at bolster 5 and framework 3, its relative position might not just in time make bolster 5 be in suitable position.The installation of longitudinal towing mechanism 6 can also be provided with adjusting pad 66 between fixed flat planar 63-11 and 61-2 for convenience; Adjusting pad 66 thickness differences, the relative position of first draw-bar seat 61 and second draw-bar seat 62 also can change thereupon, therefore can make by the adjusting pad 66 of selecting different-thickness between first draw-bar seat 61 and second draw-bar seat 62 apart from the relative position between adapted framework 3 and the bolster 5, bolster 5 is kept in place, and then make the installation process of longitudinal towing mechanism 6 simpler; Simultaneously, this also helps the reliability that guarantees that bogie truck travels.Compare with the longitudinal towing mechanism that prior art provides, in this example, hinged in the elastic deformation that produces of cover 63-3 can not influence matching relationship between bolt 7 and two fixed flat planar 61-2, the 63-11, thereby can not cause that bolt 7 becomes flexible; In addition, in this example, do not have screw thread on the drawing pull bar 60, thereby can alleviate the stress concentration on the drawing pull bar 60 yet; In addition, drawing pull bar 60 can be made by casting or the mode of forging, thereby can increase longitudinal towing mechanism 6 reliability of structures, reduces its manufacturing cost.
Have in the rolling stock driving process of above-mentioned bogie truck, bolster 5 passes to drawing pull bar 60 with longitudinal traction power by ball pivot assembly 63 by first draw-bar seat 61, drawing pull bar 60 passes to second draw-bar seat, 62, the second draw-bar seats 62 with longitudinal traction power by ball pivot assembly 63 again and tractive force is passed to framework 3 again; Framework 3 passes to wheel to 1 by single stage suspension system 2 with tractive force.Because in a longitudinal direction, ball pivot assembly 63 has bigger rigidity, thereby has the function of transmitting big longitudinal traction power; Be subjected to horizontal force at bolster 5, and when transmitting horizontal forces by ball pivot assembly 63, in a lateral direction, drawing pull bar 60 can be with respect to first pull bar 61 or/and second pull bar 62 rotate a certain angle, thereby can reduce the shear deformation that longitudinal towing mechanism 6 produces in a lateral direction, make the additional lateral ratio of rigidity of bogie truck less.In the present embodiment, because the additional lateral rigidity of bogie truck is less, when transmitting transverse force, the recruitment of the lateral stiffness of bogie truck only is 10%, therefore, longitudinal towing mechanism provided by the invention can reduce the influence to the bogie truck lateral stiffness, guarantees the stability of rolling stock, and then can provide technical support for the raising of rolling stock speed.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
