ABSTRACT:
In vehicle retarding equipment having an eddy-current retarder with four windings, a battery, four control contactors, a five position actuating member and a multiple contactor for under-energizing the retarder by connecting the windings thereof in series, two by two this latter contactor is automatically controlled by opening an appropriate contact, when the real braking torque is reduced to a third of its nominal value at cold, this control being slaved either to the temperature of the rotor armature of the retarder, through a thermocontact mounted in a pocket formed in a pole-shoe of the stator opposite said armature, or to the shifting of the gear box to a low gear position, or to the time during which the actuating member is in its position corresponding to maximum energization.
