Title (EN) DETECTOR OF THE INFLATION PRESSURE OF THE TYRES OF A VEHICLE
(FR) CONTROLEUR DE LA PRESSION DES PNEUS D'UN VEHICULE
Abstract:
(EN) A detector (10) of the inflation pressure of the tyres of a vehicle is attached to the circumference of the rim (14) of a wheel and presents a resonant circuit the coupling coil (18) of which interacts with a fixed receiving coil (39). In order to increase the minimum air gap between the rotating coupling coil and the fixed receiving coil, the coupling coil (18), which turns with the rim (14) of the wheel, is arranged on the middle branch (22) of a disk-shaped ferrite core (23). The shape of the ferrite core (23) improves the magnetic coupling with the fixed receiving coil.
(FR) Un contrôleur (10) de la pression des pneus d'un véhicule peut être fixé à la circonférence de la jante (14) d'une roue et présente un circuit résonant dont la bobine de liaison (18) coopère avc une bobine fixe de réception (39). Afin d'augmenter l'écart minimum d'air entre la bobine rotative de liaison et la bobine fixe de réception, la bobine de liaison (18), qui tourne avec la jante (14) de la roue, est agencée sur la branche moyenne (22) d'un noyau de ferrite (23) en forme de disque. La forme du noyau de ferrite (23) permet d'améliorer la liaison magnétique avec la bobine fixe de réception.
