Abstract
The problem of initial instability of rear-wheel braking on cars is presented in this paper. The analysis of the braking transient process was performed, with computer simulation of the two different cases of wheel suspension: an existing one and a new proposed concept. Presented below is the behaviour of the rear wheels during braking, where the force of the wheel pressing the ground surface appears as a key parameter. The conclusion is that the existing concept, with backward oriented oscillating suspension arm, has a natural imperfection as regards a quality of adhesion of the wheel with the ground surface. The new proposed concept of the wheel suspension is given. The result of analysis shows that the natural stability of braking could be improved with the new concept, independently of existence of ABS (anti-lock braking system) on the car.
