Abstract
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.
