Specific embodiment
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
As shown in Figures 1 to 5, a kind of rail vehicle set trailer bogie frame, for the trailer bogie in rail vehicle, by the auxiliary crossbeam 4 of two curb girders, 2, main beam 3 of 1, two end carriages and two by being welded to connect integral formula frame structure.Framework 7 adopts integral solder structure, it is possible to the raising integrally-built strength and stiffness of framework, and can improve the connective stability of equipment, and can effectively simplify the attachment structure between each beam and meet lightweight requirements.
As shown in figures 1 and 3, two curb girders 1 are box structure, top board, base plate and two side plates are spliced by welding manner, and top board, base plate and two side plates all adopt steel plate.Curb girder 1 totally takes the shape of the letter U middle to recessed structure, so can reduce the main beam 3 height relative to rail level, it is also possible to for the space that the fixing offer of bolster is enough.In the box structure of curb girder 1, be welded with multiple reinforcement gusset (not shown), adopt box-shaped and in set the structure strengthening gusset and substantially increase framework overall construction intensity and rigidity.
As depicted in figs. 1 and 2, two auxiliary crossbeams 4 are symmetricly set on the both sides of main beam 3, the two ends of auxiliary crossbeam 4 are welded and fixed on the inner side side plate being connected to two curb girders 1, two auxiliary crossbeams 4 adopt seamless steel pipe, not only bulk strength does not reduce, and decreasing a lot of weld seam, processability of product structure is greatly enhanced.
The two ends of main beam 3 are respectively welded the middle part of the inner side side plate of the curb girder 1 being fixed on both sides, adopt the U-shaped docking that intersects, to ensure the intensity of docking site.Main beam 3 is box structure, and to improve the strength and stiffness of whole framework 8, main beam 3 center has an opening 5.Main beam 3 by have opening top board, there is the base plate of opening, outside side plate, opening inner side side plate are spliced by welding manner, top board, base plate, outside side plate, opening inner side side plate all adopt steel plate, are welded with multiple reinforcement gusset (not shown) in the box structure of main beam 3.Adopt box-shaped and in set the structure strengthening gusset and can improve structural strength and the rigidity of main beam 3, and the appearance of high-stress area can be avoided, make the overall anti-fatigue performance of framework be greatly improved.As shown in Figure 4, in order to improve the strength and stiffness of main beam 3 further, the lower surface of main beam 3 is plane, and the upper surface of main beam 3 is middle to recessed U-shaped structure, and main beam 3 adopts recessed U-shaped structure can also provide enough installing space for bolster 7.
The top of towing pin is fixed on bolster, towing pin inserts in the opening 5 in the middle of main beam 3, the shape of opening 5 can be circular or square, in the present embodiment, and opening 5 generally circular in shape, the size of opening 5 and the size of towing pin match, making towing pin just will not produce bigger rocking in opening 5, in vehicle operation, main beam 3 contacts with towing pin, utilize main beam 3 to transmit the force to towing pin, then passed to bolster and car body by towing pin.In order to avoid in vehicle operation, towing pin produces to wear and tear owing to directly contacting with main beam 3, the medial wall of the middle opening 5 of main beam 3 is provided with for the abrasion backing plate 6 with towing pin break-in, abrasion backing plate 6 may select steel plate or nylon sheet according to the material of towing pin, abrasion backing plate 6 is fixed on main beam 3 by glue, or is fixed on main beam 3 by securing members such as screws.
As depicted in figs. 1 and 2, two end carriages 2 are connected to the both ends of two curb girders 1, and the two ends of end carriage 2 are weldingly fixed on the inner side side plate of both sides curb girder 1, end carriage 2 the strength and stiffness that can improve whole framework are set.Two end carriages 2 adopt seamless steel pipe, and not only bulk strength does not reduce, and decrease a lot of weld seam, and processability of product structure is greatly enhanced.
As shown in Figures 1 to 5, this framework is connected with car body by bolster, to recessed position in the middle of two curb girders 1, is separately provided for installing the secondary spring seat 9 of fixing secondary spring.
As it is shown in figure 5, in the present embodiment, be welded with the checking cylinder mounting seat 14 for installing fixing checking cylinder 13 at the two ends of the end carriage 1 of side, this framework 7 be installed with two checking cylinders 13 altogether, be arranged on one end of framework 7.Checking cylinder is fixed on the end, two ends of end carriage 2, and checking cylinder 13 is bolted in checking cylinder mounting seat 14, arranges checking cylinder 13 in end and can make full use of space under car, it is ensured that car body is not interferenceed with bogie after sinking.
As shown in Figure 5, on crossbeam 4 and end carriage 2, corresponding being welded with brakes flap seat 16, each crossbeam 4 and end carriage 2 are respectively arranged with two braking flap seats 16, braking flap seat 16 connects suspension rod, brake unit 15 below suspension rod support framework 7, it is achieved the hanging of brake unit 15, this kind of suspending way simple in construction, horizontal allowance is relatively big, and adaptability is higher.
As shown in Figure 5, each end carriage 2 is welded with two braking connecting lever seats 18, braking connecting lever seat 18 supports the braking connecting lever 17 corresponding to both ends checking cylinder 13 for fixing, the corresponding brake lever seat 11 that is welded with on auxiliary crossbeam 4, brake lever seat 11 is for the fixing brake lever 10 supporting and being connected with braking connecting lever 17.The piston of checking cylinder 13 is hinged with braking connecting lever 17, piston is moved along the framework horizontal direction longitudinal direction converting connecting rod to that moves, braking connecting lever 17 is hinged with brake lever 10, and brake lever 10 is connected with brake unit 15, and then passes through checking cylinder 13 and realize brake unit 15 and brake.
Also being welded with a pulley base 12 on end carriage 2 at one end, hand braking steel wire rope is walked around the assembly pulley on pulley base and is connected on the piston of checking cylinder 13, thus the personnel that realize complete hand braking onboard.
Said structure makes the overall structure of framework 7 be optimized, reduce and avoid the appearance of high-stress area, the overall anti-fatigue performance making framework is greatly improved, the stress level making integral frame controls in the scope that intensity allows, and is entirely capable of meeting the service requirement of domestic various different rail conditions and speed per hour 160 kilometers.
As it has been described above, plan content given in conjunction with the accompanying drawings and embodiments, it is possible to derive similar technical scheme.In every case it is the content without departing from technical solution of the present invention, according to any simple modification, equivalent variations and modification that above example is made by the technical spirit of the present invention, all still falls within the scope of technical solution of the present invention.
