Upper flange is formed in one structure, the intensity of upper flange and transition riser junction can be improved, the modular of leading web, median ventral plate and trailing web connects, on the one hand stress can be made to offset, prevent poly-power at a, cracking or bending occur, on the other hand, it is easy to local and increases web intensity, increase web material utilization rate；It is provided with the middle lower wing plate of extension, can further improve the intensity of cervical region, it addition, middle lower wing plate and rear lower wing plate can be integrally formed.
Further, the contact portion between each parts all connects fixing by the way of welding, and welding makes overall structure more firm.
Further, being provided with a front reinforcing plate being parallel to leading web between described upper flange and front lower wing plate, front reinforcing plate is distributed in the top of middle lower wing plate and front lower wing plate junction, can be effectively improved the compressive strength at a.
Further, the longitudinal cross-section of described front reinforcing plate is right-angled trapezium, and the stiffening effect making front reinforcing plate is more preferable.
Further, it is provided with a middle reinforcing plate being parallel to median ventral plate between described front lower wing plate and middle lower wing plate, can further improve the compressive strength at a.
Straight frame semitrailer described in the utility model, its straight frame semitrailer is provided with above-mentioned modular straight frame semitrailer longeron, can suitably reduce vertical depth of beam H1 above traction pin plate, increases stability and the safety of car load.
This utility model is compared with prior art had the beneficial effect that
Modular straight frame semitrailer longeron described in the utility model, when reducing vertical depth of beam H1 above traction pin plate, it is possible to meet the intensity (at a) at cervical region variable cross-section, effectively increase the utilization rate of web material；Straight frame semitrailer described in the utility model, effectively reduces vertical depth of beam H1 above traction pin plate, adds stability and the safety of car load.
