Chapter 18 Driving Axle Final drive effects on ground clearance and floor height The size of drive axle intermediate part– H influences not only the body floor height but also the minimum ground clearance h0 . To avoid too small ground clearance and too high floor, the height of drive axle should be reduced, that is, minimize the number of driving gear teeth with required ratio and satisfied gear strength. The size of drive axle is mainly determined by the size of driven bevel gear of final drive
