4 Description In this document you will find the formulas for calculations of some dimensions e.g.: Top of frame to ground at centre line of front axle at chassis weight Top of frame to ground at centre line of front axle at max axle weight Top of cab roof to ground at chassis weight. The formulas for the calculations are divided in a front and a rear part and by configuration and suspension. The tables are valid for P-, G- and R-series and are presented on the same page as the formulas for the calculations of the chassis dimensions. The height calculation is a preliminary attempt to foresee the height. There are many factors that affect the height. The tolerance in the calculation is approximately +/-25 mm if the appropriate weights are used. When applicable the BEP-codes according to standard ISO :2006 are given in addition with the Scania names. If nothing else is stated mm and kg should be used as units in the calculations. 4

5 Definitions A (L011) Axle distance AT (L015) Theoretical axle distance. Distance between front and rear load distribution centres. E (H042.2) Distance between upper edge of frame and upper edge of tyre at 2 nd front axle (8x2, 8x4 and 8x2*6). At parallel max. compression. F Distance between upper edge of frame and upper edge of tyre at 2 nd front axle (8x2, 8x4 and 8x2*6). At parallel max. axle load. H Distance between rear tyre inner edges KA KB M NA NB (W003.1) Max. distance between front wheel outer bolts (W003.n) Max. distance between rear wheel outer edges on double mounted tyres.
