Transducer device for electrically operated brakes
TLDR
An electro-mechanical pressure responsive control system and apparatus for controlling the current supplied to the actuating coils of electric brakes of a towed vehicle is described in this paper, which includes a transducer having a flexible bellows with a powdered magnetic material received therein which, when compressed by foreshortening of the bellows due to operation of the brake system of a towing vehicle, decreases in electrical resistance and thereby supplies greater current to the brakes of the towed vehicle, and vice versa.Abstract:
An electro-mechanical pressure responsive control system and apparatus for controlling the current supplied to the actuating coils of electric brakes of a towed vehicle. The control includes a transducer having a flexible bellows with a powdered magnetic material received therein which, when compressed by foreshortening of the bellows due to operation of the brake system of a towing vehicle, decreases in electrical resistance and thereby supplies greater current to the brakes of the towed vehicle, and vice versa. A magnetic field prevents the powdered material from becoming permanently compacted by repeated cycling of the bellows.read more
