发舱上边梁总成及具有该发舱上边梁总成的发舱总成
摘要：
本实用新型属于发动机领域，具体公开了一种发舱上边梁总成及具有该发舱上边梁总成的发舱总成，发舱上边梁总成包括上边梁外封板和上边梁内封板，所述上边梁外封板和所述上边梁内封板焊接在一起形成腔体；其中：所述上边梁外封板为横切面大致为“几”型的一体成型结构。本实用新型的上边梁外封板为横切面大致为“几”型的一体成型结构，减少了发舱上边梁总成的分件的个数，减少了模具开发成本，降低了焊接匹配的复杂程度，同时提高了上边梁总成的前段的碰撞吸能性和上边梁总成的后段的支撑性能。
摘要（英）：

The utility model belongs to the engine field specifically discloses a that sends out cabin roof side rail assembly and have this cabin roof side rail assembly sends out cabin assembly, and send out acabin roof side rail assembly and include roof side rail outer seal plate and roof side rail inner sealing plate, roof side rail outer seal plate with roof side rail inner sealing plate welding together formation cavity, wherein: roof side rail outer seal plate is the cross section roughly for the integrated into one piece structure of " nearly " type. The utility model discloses a roof side railouter seal plate is the cross section roughly for the integrated into one piece structure of " nearly " type, has reduced the number of the branch spare of a cabin roof side rail assembly, has reduced mould development cost, has reduced the complexity that the welding is matchd, has improved the support performance of the back end of collision energy absorption property and the roof side rail assembly of the anterior segment of roof side rail assembly simultaneously.
