A ROAD VEHICLE SUSPENSION UNIT AND A METHOD OF CONSTRUCTING A ROAD VEHICLE SUSPENSION UNIT AND FITTING THE ROAD VEHICLE SUSPENSION UNIT TO A ROAD VEHICLE

摘要

With reference to the accompanying drawing the present invention provides a suspension unit for a road vehicle which is pre-assembled prior to attachment to a road vehicle structure. The suspension unit which comprises: a wheel hub (10); a first mount (20) attachable to the road vehicle structure; a second mount (21) attachable to the road vehicle structure at a position spaced below the first mount (20); an upper suspension arm arrangement (18) connecting the wheel hub (10) to the first mount (20); and a lower suspension arm arrangement (19) connecting the wheel hub (10) to the second mount (21). The upper (18) and lower (19) suspension arm arrangements are pivotally attached to both the wheel hub (10) and the first (20) and second (21) mounts whereby when the suspension unit is attached to the road vehicle structure then the wheel hub (10) can pivot about the first (20) and second (21) mounts to move vertically relatively to the road vehicle structure. In the method of the invention one or more of the suspension units are assembled at a first location and then the assembled suspension unit(s) is/are are transported to either a second location and fixed to vehicle structure there or transported to a plurality of different locations and fixed to plurality of differently configured road vehicle structures.
