For automatically neutralizing the energization of a speed reducer adapted to brake an axle of a heavy vehicle, when the deceleration of this latter exceeds a predetermined threshold, the movements are used of a mass, such as a drop of mercury, adapted to ascend under the effect of its inertia a ramp inclined with respect to the axis of the vehicle by an angle A whose tangent is equal to (m/M) tg alpha , M being the total mass of the vehicle, m the mass applied to the braked axle and tg alpha the coefficient of adhesion between the wheels of this axle and the ground. |
