A four-wheel drive vehicle has a front solid drive axle suspension and a rear solid drive axle suspension. The vehicle has a CG height of 20.5 in, a wheelbase of 108.5 in, and tires of 15 in radius. Also, 60% of this vehicle's total drive force is developed on the front axle, and 55% of this vehicle's brake force is developed on the front axle. i) Determine ratios of e/d¡ and e./d; that will provide 100% anti-dive during braking. ii) Given your answers to Part i) find a ratio of K/Kr that will result in a zero pitch rate during driving (i.e. positive acceleration).

Figure 1 shows a railroad wagon axle and forces acting over it. There are two disc brakes on the wagon axle. Since the wagon wheels are not driven wheels, the load bearing element to which the wheels are connected is called axles. The axle is supported at both ends with bearing A and bearing B and the the weight of the wagon (G) is evenly distributed on both bearings (as G/2). During braking, two disc brakes on the axle are applied Ff force and Ft friction forces are formed on the wheels. Therefore the axle is forced to bend in the vertical direction with the effect of wagon weight (G) and wheel reaction forces (Rt), and in horizontal direction with the effect of braking (Ff) and wheel friction (Ft) forces. At the same time, the axle is forced under torsion because of Ff and Ft forces.
