Title
(EN) METHOD AND APPARATUS FOR DETECTING AN IMPROPERLY ADJUSTED SLACK ADJUSTER FOR BRAKES
(FR) PROCEDE ET APPAREIL DE DETECTION D'UN DISPOSITIF DE RATTRAPAGE DE JEU DE FREINS MAL REGLES
Abstract
(EN) Actuators move the brake linings of the brakes of a vehicle into contact with the respective friction surfaces, resulting in a temperature increase in the brake linings. Temperature sensors are embedded in the brake linings of each brake assembly on each axle of the vehicle. The temperature of each brake lining is measured and compared with the temperature of the brake lining of its brake pair on the same axle. If the ratio of the two brake lining temperatures achieves a predetermined limit, a slack adjuster is deemed out of adjustment and a warning signal is sent to the vehicle operator.
(FR) Lorsque les cylindres de freins mettent les garnitures de freins en contact avec leurs surfaces de frottement respectives, ces dernières subissent un échauffement. Des capteurs de température sont placés dans les garnitures de chacun des freins d'un essieu du véhicule, et la température de chacune desdites garnitures est mesurée et comparée à celle de l'autre garniture du même essieu. Si le différentiel de température des deux garnitures atteint une limite prédéterminée, cela est censé indiquer que le dispositif de rattrapage de jeu a dépassé sa limite de réglage, et un signal d'alarme est envoyé au conducteur du véhicule.
