Carcass for large capacity vehicles, and especially omnibuses, has large volume hollow profiles with not-completely symmetrical cross section forming pillars and longitudinal and transverse beams of main frame

摘要

The carcass comprises a main frame(1) forming its vertical and horizontal corners, and auxiliary and reinforcing elements(18-21) fitted into it. At least the pillars(6,7) and longitudinal(2-5) or transverse(15,16) spars forming the horizontal and vertical corners of the main frame are formed by large volume hollow profiles with a not-completely symmetrical cross section. The longitudinal beams(34) and also the cross members(35) of the ladder frame forming the underframe(33) are formed by profiled material sections having cross section which is open on one side.
