Abstract
The utility model relates to a spring plank for a railway wagon bogie truck, and the spring plank is characterized in that the spring plank is composed of a spring plank body, a baffle plate, a reinforcing plate and a liner plate; the spring plank body is of a groove-shaped structure; the outer ends of two large holes of two ends of the spring plank body are provided with compensating groove structures; the reinforcing plate is of a circular arc structure. The spring plank adopts a high strength weathering steel plate to be integrally pressed into a groove-shaped structure, and the liner plate, the baffle plate and the reinforcing plate which are used for positioning the bogie truck and limiting the lateral movement of a swing bolster are assembled and welded on the spring plank. The spring plank is a major component of a shake table swing mechanism, linking two side frames together to ensure the synchronous lateral swing of the two side frames. Meanwhile, the spring plank improves the diamond resistant rigidity of the bogie truck, thereby improving the critical speed of the bogie truck.
Description
Technical field
The utility model relates to a kind of novel railway roller bearing adapter stabilizer bar spring plank, belongs to the railway vehicle parts.
Background technology
Traditional three-major-items formula roller bearing adapter stabilizer bar is little owing to diamond resistant rigidity, poor performance, so running velocity is not high.Swing type bogie has adopted the shaketable pendulum-type mechanism that is similar to passenger car bogie, make bogie truck laterally have the two stage stiffness characteristic, increased the lateral flexibility of vehicle greatly, improved the transversal dynamic performance of vehicle, reduce the abrasion between wheel track, improved the riding quality of vehicle.But because supporting plate is rested the head on poor performance aspect the cross motion being used to locate bogie truck spring and restriction, the bogie side frame teeter have to asynchronous, diamond resistant rigidity is little, performance out of reach requirement sometimes.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, provides a kind of diamond resistant rigidity height, rail freight functional, that running velocity is high, its teeter of assurance side frames is carried out synchronously to turn round the frame spring plank.The technical solution of the utility model is: a kind of railway freight car bogie spring plank is made up of spring plank body, baffle plate, gusset and backing plate, and its spring plank body is a bathtub construction, adopts the laser beam cutting blanking, the single cavity die once-forming; Outer end at the two ends of spring plank body macropore is provided with the relief groove structure.Gusset adopts arc-shaped structure, and the end height is identical with fillet weld size, and behind the spring plank body assembly welding grinding process is carried out in end and weld seam, reaches gusset and spring plank body rounding off.This spring bracket plate body is that bathtub construction is to be formed by high-strength weathering steel slab integral die mould, and thereon assembly welding backing plate, baffle plate, gusset etc.; Its backing plate is used to locate the bogie truck spring, and baffle plate and gusset are used to limit the bolster cross motion, play safety catch.Outer end at the two ends of spring plank body macropore is provided with the relief groove structure, to reduce the stress concentration of baffle group postwelding, prevents that the spring plank body from use cracking.Gusset has adopted arc-shaped structure, the end height is identical with fillet weld size, with behind the spring plank body assembly welding grinding process is carried out in end and weld seam, reach gusset and spring plank body rounding off and eliminate the purpose of toe of weld defective, reduce the stress concentration behind the gusset assembly welding, prevent that the spring plank body from use cracking.
In sum, this spring plank becomes bathtub construction by high-strength weathering steel slab integral die mould, and thereon assembly welding backing plate, baffle plate, gusset etc., be used to locate bogie truck spring and restriction bolster cross motion.Spring plank is the important component part of shaketable pendulum-type mechanism, and it links together two bogie side frames to guarantee that its teeter carries out synchronously, and spring plank has also improved the diamond resistant rigidity of bogie truck simultaneously, thereby has improved the bogie truck critical speed.

The specific embodiment
Referring to above-mentioned accompanying drawing, the railway freight car bogie spring plank is characterized in that described spring plank is made up of spring plank body 1, baffle plate 2, gusset 3 and backing plate 4; Its spring plank body 1 becomes bathtub construction for high strength anti carbon steel sheet single cavity die, and it is to adopt laser beam cutting blanking, single cavity die once-forming; The outer end of the two ends macropore of spring plank body 1 is provided with relief groove structure 5, and gusset 3 is an arc-shaped structure.This spring plank is a bathtub construction, form by high-strength weathering steel slab integral die mould, and thereon assembly welding backing plate 4, baffle plate 2, gusset 3 etc.Outer end at the two ends of spring plank body 1 macropore is provided with relief groove structure 5, to reduce the stress concentration of baffle group postwelding, improves the strength at repeated alternation at this position.Gusset 3 has adopted arc-shaped structure, the end height is identical with fillet weld size, with behind the spring plank body assembly welding grinding process is carried out in end and weld seam, reach gusset 3 and spring plank body 1 rounding off and eliminate the purpose of toe of weld defective, reduce the stress concentration behind gusset 3 assembly weldings, improve the strength at repeated alternation at this position.Spring plank body 1 adopts laser beam cutting blanking, single cavity die once-forming.The spring plank assembly welding adopts the robot automated welding, and postwelding carries out whole temper, to eliminate welding stress.
