Abstract
An all- butted structure for the connection joint of a side beam and a cross beam in a bogie framework is characterized in that a side beam and a cross beam are in all-butted connection through a connecting seat; the connecting end of the side beam and the inner standing plate of the side beam form a plate-plate butted joint structure; and the connecting end of the cross beam and the cross beam form a pipe-pipe butted joint structure. The novel side beam and cross beam connection joint ensures that the side beam and the cross beam of the framework are in all-butted connection, at the same time, the connecting seat is utilized to lead a connection welding seam to split a cross section with higher stress and an area with large shape alteration, from the welding structure theory, the most ideal joint structure is realized, specifically, the welding joint has the smallest stress concentration, smallest filling amount for welding, and smallest welding residual stress and deformation. In addition, the shape of the structure is continuous and attractive; and the carrying capacity and the fatigue resistance are strong. The all- butted structure makes a breakthrough in the traditional technology that the side beam and the cross beam both adopting finished products are combined into the framework, and has the advantages exceeding the angle connection structure or angle connection and butt connection combined structure in the prior art; and the all-butted structure is superior to the overlapped structure overwhelmingly.
Description
Technical field
The utility model relates to the full docking structure of a kind of framework side crossbeam jointing.
Background technology
Framework side crossbeam jointing structure can't realize full docking structure connection because of design philosophy limitation and assembly welding technique restriction, and side crossbeam interface majority is designed to corner connection structure or corner connection and docks co-ordinative construction; Individual other also has bridging arrangement.Thus, particularly the welded seam area stress concentration factor is bigger in side crossbeam joint, has reduced the fatigue life of framework, affects the load-carrying capacity and the running velocity of bogie truck.
The utility model content
Technical problem to be solved in the utility model provides a kind of full docking structure of truck frame side crossbeam jointing of welded seam area stress concentration minimum, with this fatigue life of improving framework, makes the bogie truck operation more safe and reliable.
For solving the problems of the technologies described above, the utility model provides a kind of truck frame side crossbeam jointing full docking structure, it is characterized in that: curb girder realizes that by Connection Block full butt joint is connected with crossbeam, its curb girder coupling end and curb girder inner vertical plate form plate-plate abutment joint structure, and its crossbeam coupling end and crossbeam form pipe-pipe abutment joint structure.
The curb girder that the utility model is new makes truck side sill and crossbeam realize that full butt joint is connected with the crossbeam jointing, simultaneously, utilize Connection Block to make attachment weld avoid higher cross section and the big zone of alteration of form of stress, this is optimal joint design theoretically from welded structure, that is: welded joint place stress concentration minimum, welding loading minimum, welding residual stress and distortion are minimum; Construction profile is continuous, attractive in appearance; Load-carrying capacity and anti-fatigue ability are strong.The utility model has been broken through curb girder and crossbeam and has been behind the finished product traditional handicraft of synthetic framework again, and its advantage far is more than the corner connection structure of existing structure or corner connection and docks co-ordinative construction, is superior to bridging arrangement more greatly.
Description of drawings
Accompanying drawing is the full docking structure scheme drawing of side crossbeam jointing.
The specific embodiment
With reference to accompanying drawing, curb girder realizes that by Connection Block 2 full butt joint is connected with crossbeam 1, and its curb girder coupling end and curb girder inner vertical plate 5 and guide pillar 3 form plate-plate abutment joint structure, its crossbeam coupling end and crossbeam form pipe-pipe abutment joint structure, the 4th, upper cover plate, the 6th, lower cover, the 7th, curb girder is strengthened dividing plate.
Assembly welding technique: Connection Block and crossbeam pipe assembly welding---crossbeam composition assembly welding---Connection Block and curb girder groove inner vertical plate and guide pillar assembly welding---curb girder is strengthened dividing plate and upper cover plate assembly welding---framework integral assembly welding.
