Abstract

Η λειτουργία της συσκευής για την μεταφορά των μη κανονικών ορίων πίεσης του εσωτερικού των ελαστικών τροχών στο θάλαμο οδήγησης γίνεται με την βοήθεια δύο μονωμένων μεταλλικών ταινιών (2, 3) ή τεσσάρων μεταλλικών ταινιών (58, 56, 57, 59) ή (50, 52, 51, 53) που είναι ειδικά τοποθετημένες είτε σε κενό διάστημα μέσα στο τύμπανο πέδησης είτε εξωτερικά αυτού και παίζουν το ρόλο είτε ενός πυκνωτή είτε δύο πυκνωτών σε ένα ηλεκτρονικό κύκλωμα (10, 1, 35, 3, 2, 7, 5, 9, 14, 40, 41, 42, 19, 20, 10, 105, 106, 107) και ενός αισθητήρα πίεσης (1) που αποτελεί ένα είδος διακόπτη ενεργοποίησης των παραπάνω κυκλωμάτων. Οι μεταλλικές ταινίες (2) ή (56, 57) ή (50, 51), βρίσκονται στην περιστρεφόμενη ρόδα και οι άλλες ταινίες (3) ή (58, 59) ή (52, 53) στο ακίνητο τμήμα της ρόδας ή του πλαισίου, πολύ κοντά και σε παράλληλη θέση με τις πρώτες ταινίες (2) ή (56, 57) ή (50, 51), ώστε να αποτελέσουν πυκνωτή. Το ηλεκτρονικό κύκλωμα παράγει εναλλασσόμενη τάση η οποία εφαρμόζεται στους οπλισμούς των πυκνωτών (2, 3) ή (56, 58) και (57, 59) ή (50, 52) και (51, 53) όταν ο αισθητήρας πίεσης (1) κλείσει κύκλωμα σε περίπτωση μη κανονικών πιέσεων. Το κύκλωμα διαρρέεται από εναλλασσόμενο ρεύμα που ενεργοποιεί την ένδειξη (5) ή και (11). Στην περίπτωση του κυκλώματος με τους δύο πυκνωτές (56, 58) και (57,59) ή (50, 52) και (51, 53) ο αισθητήρας πίεσης (1) παρεμβάλλεται μεταξύ των οπλισμών (56, 57) ή (50, 51) και το εναλλασσόμενο ρεύμα δεν διέρχεται μέσω του ρουλεμάν και παρακάμπτεται έτσι το πρόβλημα της ηλεκτρικής αντίστασης που μεταβάλλεται λόγω λίπανσης των σφαιριδίων του ρουλεμάν. Η ζεύξη μεταξύ κινητού και ακινήτου μέρους του τροχού για την μετάδοση της πληροφορίας, κανονικής ή μη πίεσης στους τροχούς, μπορεί να επιτευχθεί και με χρήση επαγωγικής ζεύξης αντί χωρητικής, οπότε και αντικαθιστώνται οι μεταλλικές ταινίες (2, 3) ή (56, 58, 57, 59) ή (50, 51, 52, 53) με πηνία. Επίσης η μετάδοση της πληροφορίας μπορεί να γίνει με ζεύξη εκφόρτισης, όταν αντικατασταθούν οι μεταλλικές ταινίες (2, 3) με σύστημα ακίδας (111) και μεταλλικού δακτυλίου (112). ω
