Abstract
The utility model relates to a passenger train locomotive top structure belongs to the passenger train production field. Article six, erect the both ends and long roof beam no. 1 and two welding on the long roof beam of roof beam no. 1, middle cross beam no. 1, middle cross beam no. 2 welds with perpendicular roof beam no. 2 respectively, middle cross beam no. 1 and middle cross beam have welded vertical strengthening rib between two, it has horizontal strengthening rib to erect to weld between roof beam no. 2 and the preceding window skeleton, mouthful skeleton of fleing welds with horizontal strengthening rib and vertical strengthening rib, preceding window skeleton and middle cross beam weld the car light skeleton between one, preceding window skeleton and middle cross beam weld the car light skeleton between two, middle cross beam no. 1 is through strengthening rib and the welding of long roof beam, middle cross beam no. 2 is through strengthening rib and two welding on the long roof beam. The utility model has the advantages of: novel structure regards as solitary module to weld at the locomotive top, links up closely between the skeleton, and the shaping is effectual. It is more novel to design, adopts the streamlined design scheme, and the outward appearance is smooth, and aerodynamic drag is little, and application effect is good in the operating condition.
Description
Technical field
The utility model belongs to bus coating field, refers in particular to a kind of roof module.
Background technology
At present, the production in passenger car crown portion, often adopt Conventional wisdom to weld the position of headstock top longitudinal beam sector tube and some crossbeams, form an overall headstock skeleton, in production, operating personal is more concentrated, and production efficiency is low, be not suitable with the requirement of new type passenger car high-speed cruising, poor quality controls, and profile transitions is bad, unsightly.
Along with the development of Bus & Coach Industry, passenger vehicle running velocity is greatly improved, and has had higher requirement to the production technology of headstock, and the Main Load suffered by headstock is bending, torsion, lateral loading and longitudinal loading.Wherein flexural load mainly results from the quality of headstock, mobile unit; Torque load results from the asymmetric supporting that road roughness causes vehicle body, with the moment of torsion of static maximum possible, can namely simulate the ultimate limit state of a wheelie; Lateral loading mainly results from centrifugal effect when turning to; Longitudinal loading results from force of inertia effect when acceleration, braking.Need aborning to calculate in detail the distribution of stress situation of headstock skeleton under actual condition, horizontal curvature operating mode, limit twisting conditions, break turn operating mode, emergency braking operating mode are carried out to simulation calculation to analyze body structure strength and stiffness, and designed corresponding headstock skeleton.
Summary of the invention
The utility model provides a kind of coach roof structure, low to solve traditional passenger car skull frame production efficiency, is not suitable with the requirement of new type passenger car high-speed cruising, and poor quality controls, and profile transitions is bad, inaesthetic problem.
The technical solution of the utility model is: the two ends of six vertical beams one are welded with long beam one and long beam two, the two ends of vertical beam two are welded with long beam one and long beam two, vertical beam one is parallel with vertical beam two, center member one, center member two welds with vertical beam two respectively, waling has been welded between center member one with center member two, cross reinforcing is welded with between vertical beam two and transparent part for front sight skeleton, escaping exit skeleton welds with cross reinforcing and waling, car light skeleton is welded with between transparent part for front sight skeleton and center member one, car light skeleton is welded with between transparent part for front sight skeleton and center member two, center member one is welded with long beam one by reinforced rib, center member two is welded with long beam two by reinforced rib, long beam one, long beam two, vertical beam one, region between vertical beam two is covering one district, vertical beam two, center member one, center member two, transparent part for front sight skeleton, region between escaping exit skeleton is covering two district, long beam one, region between center member one and reinforced rib is covering three district, long beam two, region between center member two and reinforced rib is covering three district, transparent part for front sight skeleton front end is covering four district, position in the middle of transparent part for front sight skeleton is transparent part for front sight district, position in the middle of escaping exit skeleton is escape window district.
The utility model has the advantage of: novel structure, headstock top is welded as independent module, be connected closely between skeleton, good forming effect.It is more novel to design, and adopts airflow design scheme, and outward appearance is smooth, and air resistance is little, and in actual condition, effect is good.
Accompanying drawing explanation
