Abstract
The utility model discloses a connection structure for a sub-frame of a steering frame. The connection structure comprises a sub-frame and a bearing saddle; the sub-frame and the bearing saddle are connected and fixed through pull rivets; the sub-frame comprises an arm part and an end part; the end part comprises two connection holes which are used for riveting the bearing saddle; and the diameter of the connecting holes is 1-1.5 mm larger than that of the pull rivets. As the combined connection structure for the sub-frame of the steering frame is adopted in the utility model, the dead weight of the assembled rear wheels on radial devices can be greatly reduced, the weight under the steering frame spring is reduced, the dynamic action force of a wheel rack can be effectively reduced, and the dynamic performance of vehicle can be improved; the sub-frame and the bearing saddle are connected by the pull rivets, thus, the sub-frame only bears longitudinal and horizontal loads, the stress state of the sub-frame is improved, and the fatigue life of the sub-frame can be effectively prolonged; as the sub-frame is connected with the bearing saddle by pull rivets, when the bearing saddle is worn to the limit, only the bearing saddle is required to be assembled and replaced, thus, the manufacturing and overhaul usability of the sub-frame is improved, and the manufacturing and maintenance cost of the sub-frame is reduced.
Description
Technical field
The utility model belongs to the railway transportation device and manufactures and designs the field, and especially the bogie truck of railway truck manufactures and designs the field, particularly the secondary framework connection structure of bogie truck.
Background technology
Bogie truck is a structure common on the railway truck; For railway goods train bogie; The anti-shearing rigidity of bogie truck is to influence steadily fixed important parameter of bogie truck linear running, and the big young pathbreaker of anti-shearing rigidity directly influences the snakelike unstability critical speed of vehicle, vehicle smoothness and Derailment Safety; Bending stiffness is the important parameter that influences the bogie truck curving performance, and the big young pathbreaker of bending stiffness directly influences wheel wear speed, wheel track power size.
The secondary framework radial steering of existing railway truck mainly comprise wheel to, bogie side frame, bolster, wheel to radially device, brake equipment.Secondary framework radial steering core technology wheel mainly is made up of secondary framework, pipe link and round pin mechanism radially, and two secondary frameworks fall within the bogie truck two-wheeled respectively to last, and two secondary frameworks are connected through round pin with two pipe links, and formation is taken turns mechanism radially.Existing secondary framework is made up of saddle, arm, and saddle and arm adopt casting integrated structure.In the utilization process, load vertical, vertical and horizontal that secondary framework bears have enough strength and stiffness for guaranteeing secondary framework, and the saddle of secondary framework carries the position need have bigger wall thickness and sectional area.
Summary of the invention
The utility model discloses the secondary framework connection structure of a kind of bogie truck according to the deficiency of prior art.The problem that the utility model will solve provides the secondary framework connection structure of a kind of compound type.
The utility model is realized through following technical scheme:
The secondary framework connection structure of bogie truck comprises secondary framework and adapter, it is characterized in that: said secondary framework is connected fixing with adapter through pulling rivet.
Further said secondary framework comprises arm and end, and said end comprises that two are used connecting bore with the riveted joint of said adapter.
The diameter dimension of said connecting bore is greater than the diameter dimension 1mm～1.5mm of pulling rivet.
The secondary framework of above-mentioned bogie truck is when combinations produce; Can at first cast the secondary framework structure that comprises arm and end; And carry out connecting bore fine limit work and secondary framework fine limit work, be connected the fixed orifice coupling on connecting bore and the adapter, process secondary framework and adapter after; Connect fixingly through pulling rivet, the diameter of connecting bore, comprise that connection fixed orifice diameter on the adapter is greater than the diameter 1mm～1.5mm of pulling rivet.
The utility model helpfulness: the utility model adopts the secondary framework connection structure of combination truck, and partition processing can realize that working accuracy is more expensive lower, and quality with product helps enhancing productivity; Secondary framework and adapter adopt the split casting structure, have reduced the assembling trailing wheel significantly to the radially deadweight of device, have alleviated the bogie truck unsprung weight, can effectively reduce the wheel track action firmly, improve the dynamic performance of vehicle; Adopt pulling rivet to connect between secondary framework and adapter, secondary framework only bears the load of vertical and horizontal, has improved the force-bearing situation of secondary framework, can effectively prolong the fatigue life of secondary framework; Adopt pulling rivet to connect between secondary framework and adapter, adapter wears and tears in limited time, only need decompose the replacing adapter, can improve manufacturing, the maintenance manufacturability of secondary framework, reduces manufacturing, maintenance cost.

The specific embodiment
Through the specific embodiment and accompanying drawing the utility model is further specified below.Embodiment is used to explain the utility model, limits the utility model never in any form.
In conjunction with Fig. 1 to Fig. 4.
As shown in the figure, the secondary framework connection structure of bogie truck comprises secondary framework 42 and adapter 41, and secondary framework 42 is connected fixing with adapter 41 through pulling rivet 11.
The diameter of connecting bore 61 is greater than the diameter 1mm～1.5mm of pulling rivet 11.
Fig. 1 is pipe link 12 connections of two secondary frameworks 42 through two intersections, and the junction is positioned at secondary framework 42 arms 51, connects to adopt round pin 13.Fig. 2 and Fig. 3 are secondary framework 42 structures of the utility model, constitute by the end 52 at arm 51 and two ends since with secondary framework saddle partition casting; The foundry engieering difficulty reduces greatly; The casting accuracy rate significantly improves, and has improved quality and the precision of monolithic wheel to radially installing, and has reduced productive costs; End 52 comprise two with 41 riveted joints of said adapter with secondary framework connecting bore 61.The secondary framework 42 of Fig. 4 is connected fixed sturcture with adapter 41; The utility model adopts pulling rivet 11 fixing, and fixed sturcture is firmly stable, wears and tears convenient the fractionation in limited time at adapter 41; Positioning boss 73 has played positioning action well on the adapter 41, and convenience also helps improving structure precision.
The secondary framework of the utility model bogie truck is when combinations produce; Can at first cast the secondary framework structure that comprises arm 51 and end 52; And carry out connecting bore 61 fine limit works and secondary framework 42 fine limit works, be connected the fixed orifice coupling on connecting bore 61 and the adapter 41, process secondary framework 42 and adapter 41 after; Connect fixingly through pulling rivet 11, the diameter of connecting bore 61, comprise that connection fixed orifice diameter on the adapter is greater than the diameter 1mm～1.5mm of pulling rivet 11.
