HANDLING CHARACTERISTICS OF FOUR-WHEEL DRIVE VEHICLES

When applying the four wheel drive concept to road vehicles it is important to distribute the drive force efficiently to the front and rear axles in order to obtain optimum traction and driving safety. The paper presents the results of theoretical analysis, in the course of which the acceleration capability during cornering has been investigated. Any mathematically definable spiral can be used to define the curve. In the following examples, a track with a clothoid path has been chosen, further, the paper investigates vehicle during steady state cornering, power-off reaction, and braking responses in a turn, for the cases of a tail-heavy and a nose-heavy vehicle, with various drive configurations and under different road conditions.
