Effect of Tractive Force on Directional Stability and Controllability of Vehicles 690527

Theoretical calculation and experiments are made to make clear the transient response of a front wheel drive vehicle to change in tractive force. If the tractive force acting on the front wheel is reduced suddenly from a large stationary value, the turning radius decreases rapidly, and the stability and controllability of the vehicle decreases.
The following means are effective to improve stability and controllability: establish relations ∂C1/∂D1 > 0 and ∂T/∂D1 < 0; make the value of C1 + C2 as large as possible; maintain a relation C1 < C2; and increase rigidities of shafts and links of steering system, where C1, C2, T, and D1 are the cornering coefficient of the front wheel, that of the rear wheel, the aligning torque of the front wheel, and the tractive force at the front wheel, respectively.
