Motor caravan chassis construction - has narrow subframe with power unit flanged to inclined members of wide frame with vertical step where flanged

摘要

The chassis (1) is intended for a motorised caravan and comprises longitudinal (5,11,13) and transverse (6,12) bars with the power unit (7) arranged at a narrower end of the chassis. It comprises two sub-frames (2,3) of different widths with a screw connection between them. The shorter frame (2), which carries the power unit, has longitudinal members (5) with outwardly inclined flanges (4) to which correspondingly inclined longitudinal members (13) of the longer and wider frame (3) are secured by screw bolts. At this point, the members (5,13) have a vertical step (10) in their upper surface whilst their lower surfaces are in one plane.
